UTC-only wording is a routine simplification. + +For M-2/I-1, app ID 15368 binds a check producer, not a workflow body or trusted source revision. +Workflow/tool changes and the actual run therefore remain subjects of maintainer review. +The existing policy permits administrator bypass, requires zero approvals and disables code-owner review. +Duplicate check names can introduce ambiguity and block merging; the supplied report's particular instant-success duplicate bypass was not reproduced or established. +See [GitHub protection semantics](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches). + +For M-3, enforcement scope and review dismissal/bypass actors carry policy and must not be discarded as harmless metadata. +The [protection endpoint](https://docs.github.com/en/rest/branches/branch-protection#get-branch-protection) and [branch-summary endpoint](https://docs.github.com/en/rest/branches/branches#get-a-branch) have different response shapes. +The dated [actual protection fixture](../../../tools/fixtures/README.md) pins one observed body; it does not promise every future shape is supported or substitute for GraphQL/ruleset reads. +Unknown unrepresentable policy remains refused before writes. +The full read-only live policy check passed separately; a fixture is not live-drift attestation. + +For L-8, both exact compiler classes remain necessary because Cargo's parallel all-target build can expose the normal binary or test harness first; an E0152-only assertion already caused a real hosted flake. +The clean same-command control rejects an already-broken baseline before mutation without weakening the diagnostic/exit-101 requirement. +This is a controlled regression assertion under trusted tools, not a proof against nondeterministic external failure or a hostile compiler. + +For I-2/I-3, removing installed binaries narrows one cache overwrite route; it does not make registry/git/target caches integrity-attested. +[GitHub cache scope](https://docs.github.com/en/actions/reference/workflows-and-actions/dependency-caching) prevents ordinary PR merge-ref caches from restoring into the base or sibling PRs, while the same PR's reruns can restore them. +Per-ref cancellation does not bound distinct PRs; organization approval/capacity settings were not verified or changed. + +## Historical artifact reconciliation + +The ADR-0040 approval follow-up correctly uses the dedicated `conduct-approval-review` template. +That skill mandates no separate storage folder; inclusion in the code-review index does not change the artifact's declared type. +The index now makes that distinction explicit without relocation or invented process requirements. + +T-033's R1 numbered headings contain all five roles; an [additive role map](../reviews/code-reviews/2026-10-12-t033-qemu-tooling.md#supplied-review-role-heading-reconciliation-2026-10-12) makes them directly discoverable without rewriting the original review. +The T-030 security index previously summarized the cumulative final range, not an incorrect R1 claim; it now names R1 and R2 separately. +`MP-1` in later review artifacts and `MP-33` in some earlier artifacts denote the same unnumbered security-master-plan allocation-exhaustion requirement after the 32 standard items, not different or missing checks. +The latest A R2 checklist uses `MP-1`; historical labels and their 33 dispositions remain preserved. + +Historical local/hosted performance reports retain their original source identity, metadata and raw measurements. +New metadata minimization does not retroactively certify or redact every auxiliary artifact, arbitrary successful tool output or older report. +The [first hosted snapshot](perf-baseline-2026-10-12-t035-hosted-check.md) keeps its internal `ci-nightly` title because its bytes were copied from the downloaded report. +The [follow-up hosted snapshot](perf-baseline-2026-10-12-t035-pr48-followup-hosted-check.md) follows the same convention and records the changed harness at clean full `50ab72bf2c15a4d34be25a1491a357313e50390a`. +Its SHA-256 is `24c143abb0151de1eb3fb38ff3d74f3e060effd2a6c492cc8389bebca565ae85`; this is the report-file digest, not a locally recomputed artifact-archive digest. +All 20 raw samples independently reproduce p10/p50/p90 `5,232,672 / 5,473,392 / 7,277,776 ns`; no calibrated or cross-host regression verdict follows. + +## Additional PR feedback and first-round corrections (2026-10-12) + +[PR feedback PR48-CR-01](https://github.com/HodeTech/Tyrne/pull/48#discussion_r4245197038), independently corroborated by both fresh B reviewers, identified an inherited Low overclaim in the generated p99 methodology. +The original reports say p99 becomes statistically informative at `n >= 100`; that sentence is superseded by this correction and is not an endorsed reliability guarantee. +Under nearest rank, `ceil(0.99 * 100) = 99`, the second-highest sample; below 100 the selected rank is the maximum. +From 100 onward the selected rank is below the final rank, but tied values can still equal the maximum. +Crossing that rank boundary alone establishes no statistical reliability; interpret tail estimates with sample count and measurement context. +The generator now states those facts without changing calculations, raw measurements or validity thresholds. +Captured report bytes/digests remain intact, including their historical interpretive sentence; the recorded 20-sample p10/p50/p90 values remain correct. + +B Round 1 also found Low R1-INT-01: this reconciliation had attributed literal `MP-1` to the master plan, whose allocation-exhaustion requirement is unnumbered. +The paragraph above now attributes the labels to the actual review artifacts and the common requirement to the master plan. +These were coordinator-recorded corrections after the first independent round;

Runtime fix belongs to T-034. | +| PF-02 | Medium | The track requires release tests for a bare-metal BSP with no host-test target; baseline prose conflates debug/release totals. | Distinguish bare-metal compilation from host tests; correct debug 366 versus release 356 in ADR-0040 and the current banner. | +| PF-03 | Medium | Named polish is inconsistently described as gating, and optional T-036/T-056 benefits are unconditional. | Reconcile the index and ADR benefits with rule 3; T-036 is explicitly included in this requested sequence without changing the whole phase's optional-task rule. T-074's own exit-gating contract is preserved. | +| PF-04 | Medium | The scope checkpoint permits reversing Option A through a revision note. | Require a superseding ADR for outcome reversal, preserving clarification/allowed-deferral riders. | +| PF-05 | Medium | T-035 offers PR-gated performance without a matching threshold contract; a standard edit is offered as an alternative to ADR governance. | Propose weekly/on-demand informational reporting and existing-protection JSON in ADR-0040; standards follow Acceptance. Synchronise T-035's criteria with those choices. | +| PF-06 | Medium | T-036's mandatory native commands conflict with its check-plus-Miri option, and merge policy may be decided only in task history. | Propose required native check/clippy/test plus Miri on Ubuntu ARM in ADR-0040; routine setup remains in task history. | +| PF-07 | Medium | T-037 says build scripts cannot see custom target cfgs. | Correct the distinction between Cargo's `CARGO_CFG_*` environment and host compilation of the build script; retain inline architecture-and-OS gates as the recommendation. | +| PF-08 | Medium | Conditional unsafe/security review obligations are incomplete; T-037 defers its audit synchronisation to another task. | Require distinct security review/trailers where applicable and a T-037 target-narrowing amendment to UNSAFE-2026-0033; T-038 retains the clobber amendment. | +| PF-09 | Medium | Scratch-branch probes, dependency-`Done` sequencing and pre-merge `main` evidence conflict with the requested single-branch/end-only PR workflow. | Propose isolated-copy/runner probes and the narrowly scoped stacked-execution convention; keep tasks `In Review` and distinguish local, hosted, PR and post-merge evidence. | +| PF-10 | Medium | ADR-0040/T-075 can count a recorded "yes" as completing a task whose chosen path still requires implementation. | Clarify exit-accounted permitted deferral versus chosen implementation criteria and maintainer-only `Done`. | +| PF-11 | Low | CI's permissions comment says it never uploads artifacts, which T-034 invalidates. | Add its correction to T-034's documentation criterion; keep least-privilege permissions. | +| PF-12 | Low | ADR-0040 infers categorical soundness from passing baseline checks despite acknowledging T-038's asm clobber UB. | Qualify the claim as observed boot/test behaviour; explicitly preserve the known defects and their existing task ownership. | +| PF-13 | Low | T-030's final non-release perf-bench build follows a release image overwrite without explicitly restoring the debug image. | Require a fresh matching debug userland image before perf build/lint and accurately describe the BSP's existence/change checks.

This was a baseline trace inspection; T-034 still owns executable marker enforcement and negative probes. +- `tools/smoke.sh --int --timeout 5`: PASS after restoring the 117-byte debug image; greeting, task exit/completion and no panic/fault, boot-to-end 8,298,992 ns.

Neither single-run timing is a performance-regression verdict. + +These checks establish existing evidence and correct the count claims; they do not substitute for the implementation's negative tests, hosted results, artifacts or live protection read-back.

A probe harness that correctly detects failure can pass; it must not be reported as a red production workflow. + +## Documentation + +The reviewed policy packet is ADR-0040, the Track B.2-1 sequence in the task index, T-030…T-037 and the narrowly related T-075 exit-accounting clarification. A separate ADR number is unnecessary because the governing ADR is still `Proposed`. After Acceptance, implementation updates the affected guides/standards alongside each step and performs a final cross-document reconciliation before the PR. + +Release kernel clippy and release EL0 smoke are included now. The first correction draft incorrectly claimed that hello requires a successful console call: source re-review confirmed it ignores that result and always exits. T-034 can therefore require the greeting in debug, forbid it in release, and require exit/completion with no panic/fault in both. T-065 later re-keys those expectations to its explicit feature; T-067 retains adversarial-image coverage. No source behaviour change is needed for release smoke. + +## Integration + +Read-only GitHub inspection on 2026-10-11 found a public `HodeTech/Tyrne` repository, default branch `main`, no repository rulesets and classic `main` protection with these required GitHub Actions display names: + +- `fmt + clippy + host tests (nightly)` +- `aarch64-unknown-none kernel build (nightly)` +- `host crates on stable` +- `miri (Stacked Borrows)` + +Strict up-to-date checks, linear history and conversation resolution are enabled; force pushes and deletion are disabled.

Prior A security R1/R2 are context, not a new B security verdict. The independent paired ordinary integration review is `/tmp/tyrne-pr48-docs-r1-integration.md`. +- **Requested model/effort provenance:** parent confirms `gpt-6.1-sol`, high effort, `fork_turns=none`. This is orchestration metadata, not an independent runtime model-identity attestation. +- **Scope:** all 12 changed files, 138 additions and 26 deletions; 11 Markdown documents and comment-only `ci.yml`. This full provisional report was written before waiting for the independent peer; final cross-read disposition is appended afterward. + +## Correctness + +**One B-introduced Low source-attribution finding, R1-INT-01, was discovered by the independent integration reviewer and independently confirmed during the full peer cross-read.** One inherited generated-documentation claim was independently confirmed during this round and is recorded as Low PR48-CR-01 under Documentation. No runtime or policy defect is established by either. + +- **Commands and gate descriptions:** both coverage examples now exclude BSP, `tyrne-user` and `tyrne-userland-hello`, matching `ci.yml:455`. Miri examples use repository-selected pinned nightly rather than rolling `+nightly`. The six-line ARM block now matches check → clippy → isolated rejection probe → native tests → Miri setup → Miri tests. Its four gates are check/clippy/test/Miri; the probe and setup are correctly additional operations. Both userland crates remain included, only BSP excluded. The fast-lane failure table now includes all four existing fixture families. +- **Observed timing and caches:** the ~1–2 minute Miri statement is explicitly observed, with the older 10–15 minute budget retained as history. Parent-acquired exact-B summaries independently parsed here show Miri jobs of 92 and 85 seconds. Every workflow cache key contains OS/architecture, toolchain identity (literal stable for that lane) and lockfile hash; restore prefixes omit the hash while retaining OS/architecture/toolchain. All paths omit cargo-bin. This accurately narrows one installed-executable surface without describing registry/git/target artifacts as integrity-attested. +- **Actual setup:** workflows install/cache directly per job. No shared composite action exists in the tree. Correcting the infrastructure description documents current implementation; it does not adopt a new architectural or process policy. +- **Current policy and trust:** guide/header correctly qualify branch protection by the actors it governs, preserve `enforce_admins: false`, count 0 and disabled code-owner review, and distinguish Actions producer app 15368 from workflow/source integrity. Required display names match all six canonical JSON entries. The GraphQL review-enabled boolean and REST approval count remain separately captured properties. Neither this review nor B demonstrates the supplied duplicate-name bypass. GitHub documents duplicate-name ambiguity and possible merge blocking, rather than the supplied report's specific instant-success bypass. [GitHub protection semantics](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches). +- **Capacity and external controls:** per-workflow/ref concurrency and smoke/ARM 10/15-minute bounds match the YAML. They do not bound distinct PRs. Fork approval, organization capacity and billing settings are explicitly unverified external administration, without a fictional repository-enforced limit. +- **REST schema boundaries:** the guide/reconciliation link the actual complete protection response fixture and distinguish it from branch-summary responses. The fixture equality and unknown-extension tests preserve conservative refusal; dismissal/bypass actors and enforcement scope carry policy. They must not be discarded as URL metadata. Production adapter and policy are unchanged. The reference's actor restrictions corroborate that distinction. [GitHub protected-branch API](https://docs.github.com/en/rest/branches/branch-protection). +- **Smoke and historical counts:** T-034 now names the actual `Undefined Instruction` matcher in both production smoke and fixture tuples; it retains that exact SVC counting is outside the gate. Its opening four-check reference is explicitly historical, while current protection has six checks. No stronger guest-safety claim is introduced. +- **Review/evidence mapping:** T-033's original source-bound report is retained as an exact prefix, with an additive mapping to the five canonical roles. T-030's index accurately names R1 `8437158..364b746` and R2 `8437158..5cd9ee8`; its prior cumulative compression was not an incorrect original R1 range. The ADR-0040 approval artifact is explicitly an approval review using its dedicated template; the approval skill mandates no separate storage folder. MP-1/MP-33 refer to the same allocation-exhaustion item, without another checklist item or original-disposition rewrite. The new sentence incorrectly attributes literal MP-1 to the master plan; R1-INT-01 records the source-precision correction. + +The cache paragraph is consistent with GitHub's ordinary PR merge-ref scope: the same PR's reruns may restore that cache, while base/sibling PR runs cannot. This is documented service scope, not a live cache inventory or poisoning experiment. [GitHub dependency caching reference](https://docs.github.com/en/actions/reference/workflows-and-actions/dependency-caching). + +## Style + +**Findings: none.** Actionlint 1.7.12 on both explicit workflows and immutable-range whitespace validation pass. Changed live prose restores normal word/number spaces without altering exact tokens, SHAs, job names or historic evidence. Comments now align consistently with their surrounding YAML. Repository text is English; UTC-only schedule wording is a routine simplification. The supplied allegation that the official country name itself violated English-only policy is refuted by the English-language UN announcement, and B does not encode that allegation as truth. [UN English-language announcement](https://turkiye.un.org/en/184798-turkeys-name-changed-t%C3%BCrkiye). + +No diagram, new public Rust item, unsafe contract, dependency, naming refactor or lint exception is introduced.

The new reconciliation's Historical artifact section currently preserves/links that snapshot without a dated p99 qualification. +- **Source/provenance:** root reported a new read-only CodeRabbit Minor thread on exact 683 and requested independent assessment. This reviewer did not retrieve that thread or run its embedded suggested command. The finding follows direct immutable source/snapshot inspection and integer-rank arithmetic; it is inherited PR48 generated prose, not a regression introduced by B. +- **Evidence:** nearest rank is `ceil(0.99*n)`. Direct integer evaluation gives rank 20 at n=20, 99 at n=99, and 99 at n=100. At 100 the selected order statistic is merely second-highest rather than maximum. That rank transition supplies no confidence bound, precision target, independence/stationarity assumption or tail-estimator reliability result. The unconditional claim of becoming statistically informative at 100 samples is unsupported. The current 20-sample p99/max equality and reported raw p10/p50/p90 values are correct. +- **Impact:** readers may treat an arbitrary count as sufficient assurance of tail reliability. Performance is informational with no calibrated merge threshold, so this is a narrow Low prose-quality defect, not a statistics algorithm defect or merge-safety finding. +- **Action:** revise future generated methodology to state the exact rank fact and that no universal sample count establishes p99 reliability. Preserve the existing captured baselines byte-for-byte and add an explicit dated reconciliation caveat for the inherited sentence. Keep percentile calculation, measurement thresholds and Accepted ADR unchanged. Verify generator wording with the seven scoped performance fixtures/ShellCheck and fresh cumulative Round 2. +- **Status:** open at immutable 5816c93. Root's planned correction is not certified by this report. One shared finding, not an additional duplicate count if the peer corroborates it. + +### R1-INT-01 — Low, nonblocking: literal checklist label attributed to the master plan + +- **Location:** `docs/analysis/reports/2026-10-12-pr-48-supplied-review-reconciliation.md:74` at immutable 5816c93. +- **Discovery/provenance:** the independent integration reviewer discovered this after its initial provisional report; this reviewer independently verified it during full peer cross-read, after writing the complete independent provisional code report. +- **Evidence:** the new sentence attributes `MP-1` literally to the security master plan. That file's kernel-mode discipline list at line 68 contains an unnumbered typed-allocation-exhaustion requirement, and a direct search finds neither `MP-1` nor `MP-33`. Later A R2/T-030 R2 artifacts use MP-1; earlier artifacts use MP-33 for that same extra item after the 32 standard checks. +- **Impact:** imprecise source attribution in the new reconciliation. The actual requirement, equivalence and total of 33 dispositions are correct; no missing review coverage or governance defect follows. +- **Action:** attribute MP-1 and MP-33 to later/earlier review artifacts respectively and identify the unnumbered master-plan requirement as their common source. Preserve all original review text. +- **Status:** open at immutable 5816c93; coordinator's future correction requires fresh cumulative review. One peer-discovered finding corroborated here, not a second independent count. + +No further actionable documentation defect was established. The PR body's older-source validation counts and “final tip” paragraphs remain dated historical intent/evidence; neither the B document nor this verdict treats those as exact-B source proof.

Read actual read-only `gh pr view 48` description as older source intent, complete supplied Turkish attachment, and all four complete canonical A code/security R1/R2 reports. The dedicated approval skill and relevant original approval/T-030 headings were checked to assess the reconciliation's template/range claims; no approval-promotion review was performed. All 12 B changed files and the complete new reconciliation were inspected. + +Risk classification is ordinary: correcting descriptions of existing assurance/security boundaries does not modify those boundaries.

No runtime symbol/caller, dependency graph, toolchain/action pin, permission, unsafe contract or binary changes.

The paired ordinary integration review is `/tmp/tyrne-pr48-docs-r2-integration.md`. +- **Requested model/effort provenance:** `gpt-6.1-sol`, high effort, `fork_turns=none`, as supplied by the coordinator. This records requested orchestration configuration, not an independently attested runtime identity or maintainer signature. +- **Scope:** all 15 changed files: 13 Markdown files, comment-only `ci.yml`, and seven changed report-generator echo lines. Both implementation commits and both R1 findings are reviewed cumulatively. This complete provisional report was written before waiting for the paired review; full cross-read reconciliation follows separately. + +## Correctness + +**New actionable findings: none. Both R1 Low findings are resolved at the exact reviewed source.** + +- **PR48-CR-01 — resolved:** `tools/perf-harness.sh:569–574` now states that nearest-rank p99 at N = 100 selects rank 99, the second-highest sorted observation; from N = 100 onward the selected rank is below N, while ties can still equal the maximum. It expressly says this rank transition establishes no statistical reliability. Direct integer ranks at N = 1/20/99/100/101/1000 are 1/20/99/99/100/990. Four independent synthetic generated reports exercise distinct N = 20/99/100 and tied N = 100; reported p99 and emitted wording agree. This corrects interpretation only. Every other harness byte, including aggregation, sample-validity thresholds, watchdog, source attribution, metadata and overwrite refusal, is identical to base. +- **Historical p99 qualification:** the reconciliation's dated Additional PR feedback section names the inherited unsupported sentence, supersedes its reliability implication, explains rank and ties, and explicitly preserves captured report bytes/digests. The historical 20-sample bands remain correct. It neither retrospectively changes a reviewer verdict nor claims original authors reviewed future source. +- **R1-INT-01 — resolved:** the current reconciliation attributes MP-1 to later review artifacts and MP-33 to earlier artifacts. The security master plan's kernel-mode list contains the common unnumbered typed allocation-exhaustion requirement, not either literal label. Direct source checks find the later label in A R2/T-030 R2 and the earlier label in A R1. The total remains 32 standard items plus one extra; no missing coverage or new governance rule is inferred. +- **Coverage/Miri/ARM:** both coverage examples exclude BSP and both userland crates, matching the actual workflow. Plain repository-local Cargo selects the pinned nightly; explicit stable remains confined to the stable lane. ARM order is check, all-target clippy, isolated rejection probe, native tests, Miri setup, Miri tests. The four gates are check/clippy/test/Miri, with setup/probe as supporting operations. Both userland crates remain included; only BSP is excluded. Fast-lane prose now names all four existing fixture families. +- **Timing/setup/cache:** the Miri estimate is an observed small-suite duration, with the historical budget qualified. Independently parsed service summaries show 92/85 seconds at 5816 and 68/76 seconds at 646. Actual setup is duplicated per job, with no composite action present. Exact cache keys include OS, architecture, toolchain identity and lockfile hash; restore prefixes retain the first three, omitting the hash. Stable is a rolling channel identity, not an immutable compiler version. All cache paths omit cargo-bin while registry/git/target remain trusted build inputs. +- **Protection and workflow trust:** six canonical exact contexts remain app-bound to 15368 with strict checking. Admin enforcement false, zero approval count and disabled code-owner review remain explicit. Producer binding is accurately distinguished from workflow/body/revision attestation. GraphQL review enablement and REST count are independently represented properties. The supplied particular duplicate-job instant-success bypass is not demonstrated; GitHub documents ambiguous duplicate names and possible merge blocking. No policy tightening, ruleset or new acceptance decision is smuggled into prose. [GitHub protection semantics](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches). +- **Capacity:** per-workflow/ref cancellation and actual smoke/ARM 10/15-minute bounds agree with YAML. Distinct PRs remain outside that cancellation bound. Organization approval/capacity/billing controls are correctly external and unverified here. +- **REST boundaries:** the captured complete protection response and equality/unknown-extension tests support the described observed shape. The unchanged normalizer still refuses unknown enforcement/actor fields instead of dropping them as metadata. Review dismissal/bypass fields carry policy; branch-summary name/protection_url are not evidence of the protection endpoint's schema. The dated fixture is not permanent live-drift attestation. [GitHub protection API](https://docs.github.com/en/rest/branches/branch-protection), [branch API](https://docs.github.com/en/rest/branches/branches). +- **Smoke/history:** T-034 now names the actual Undefined Instruction matcher, matching production and both-profile fixtures; exact SVC counting and adversarial EL0 remain separate. Its opening four-check count is distinguished from the current six-check policy. UTC cadence matches the performance cron. T-033 gains an additive canonical-role map, T-030's index names the actual R1/R2 ranges separately, and the ADR-0040 approval report remains correctly identified as an approval artifact using its dedicated template. + +Blocking correctness findings: **none**. Existing HIGH T-038 x2 clobber remains open and excluded, not reclassified or cleared. + +## Style + +**Findings: none.** ShellCheck 0.11.0, actionlint 1.7.12 against both explicitly named workflows and immutable-range whitespace validation pass. New live prose uses English and ordinary spaces without modifying exact contexts, source SHAs or historical evidence. YAML indentation changes affect comments only. Generated output uses existing Bash echo style and quoting; no executable control structure changes. + +UTC-only wording is a routine simplification. The supplied constitutional English-language allegation is correctly refuted by the UN's own English announcement using the official country name; the reconciliation does not encode that allegation as a violation. [UN English-language announcement](https://turkiye.un.org/en/184798-turkeys-name-changed-t%C3%BCrkiye). + +No diagram, Rust naming change, unsafe annotation, new dependency, formatter exception or speculative refactor request applies. + +## Test coverage + +Tests were read before their relevant implementations: the complete seven-method performance suite, actual report output, protection capture/equality/refusal tests, ARM clean-before-mutation flow and smoke token/source.

R1-INT-01 is corrected without rewriting old MP labels. Both complete R1 artifacts accurately preserve their findings as open at 5816 and record the coordinator's later correction, not reviewer approval of future bytes. + +The T-033 role map matches its actual sections 3–7; section 1 is verdict, section 2 read/procedure disclosure and section 8 full checklist. The later WFI/spinning correction remains intact. T-030's security report names R1 `8437158..364b746` and R2 `8437158..5cd9ee8`, agreeing with the clarified index. The approval skill's dedicated template matches the ADR-0040 approval artifact and mandates no separate storage folder. Reading that skill to validate artifact identity does not invoke a new promotion review or its unrelated full gate workflow. + +The GitHub cache reference supports ordinary PR merge-ref isolation from base/sibling PRs and same-PR rerun reuse; source inspection establishes actual key/path choices.

Plain `cargo miri test` selects the pinned repository toolchain, while explicit stable remains distinguished. ARM order matches the workflow: check, all-target clippy, private rejection probe, native test, Miri setup, Miri test. Calling check/clippy/test/Miri the four gates is accurate despite the two supporting commands. The fixture failure list now includes all four suites actually run in the fast lane. + +All exact cache keys include OS/architecture/toolchain identity and lockfile hash; restore prefixes retain OS/architecture/toolchain while omitting that hash. Stable uses the `stable` channel identity, not an exact immutable compiler version. Every actual cache path list omits cargo-bin. The source repeats setup in each job and contains no composite action. UTC cadence agrees with `17 3 * * 1`. Observed Miri timing is explicitly an observation, not a guarantee: coordinator-acquired exact-head PR/push summaries show 92 and 85 seconds respectively. + +The 17-item author reconciliation distinguishes corrections from refuted overclaims. It does not certify itself as an independent review. M-1 is correctly refuted as a language violation: the [UN's English announcement](https://turkiye.un.org/en/184798-turkeys-name-changed-t%C3%BCrkiye) uses the official country name; UTC simplification requires no constitutional repair. M-3's actor/enforcement fields carry policy; the source's exact-schema validation and fixture tests continue refusing them. The fixture covers a dated observed endpoint body, not every REST response or permanent live equality. Review enablement and approval count are separately represented; count zero remains explicit. The statement about the prior live check is historical evidence from the A reports, not a live operation performed by this reviewer. + +**New finding PR48-CR-01 — Low, nonblocking, independently corroborated from a coordinator-supplied CodeRabbit lead:** the inherited generated methodology at `tools/perf-harness.sh:565–570`, reproduced in `docs/analysis/reports/perf-baseline-2026-10-12-t035-pr48-followup-hosted-check.md:45–50`, says p99 becomes statistically informative at `n >= 100`. At n=100 the formula only selects sorted index 99, the second-highest observation; at n=20 and n=99 it selects the maximum. Crossing that index boundary provides no general sampling reliability guarantee. This is a prose overclaim, not evidence that the nearest-rank calculation or the recorded 20-sample p10/p50/p90 is wrong. + +Reproduction: inspect the two generator echo lines at 569–570 and the historical report's corresponding statement; evaluate `ceil(0.99 * n)` for 20, 99 and 100. A search finds the same inherited wording in earlier historical baselines. Correct future generated prose to explain only the rank behavior and caution that tail estimates require substantially more samples and context. Add an explicit dated caveat to the current reconciliation identifying the historical overclaim, while retaining all snapshot bytes/digests. No percentile algorithm, sample-validity threshold, regression policy or ADR change is needed. The generator is unchanged by the present B delta, but the parent explicitly requested disposition as part of B's evidence reconciliation. **Open at immutable 5816c934**; a planned correction is not certified here. + +No new Blocker, High or Medium finding was established. + +## Style + +**Clean for the changed prose/comments.** The conventional commit `docs(ci): reconcile PR48 review claims and current guidance` has valid ADR-0013/0040 references. Actionlint on both explicitly named workflows and immutable-range whitespace checking pass. New text uses ordinary English prose and correct spacing. The old tokens `binding15368`, `count0`, `remains0`, `Monday03`, `Steps1`, `Step8`, `run381`, and `CI381` no longer occur in the four live guide/standard/phase/task-index files targeted by the sweep. Dated task histories and source-bound reports intentionally retain their historical text; broad editorial rewriting would weaken provenance.

[PR CI 38213061361](https://github.com/HodeTech/Tyrne/actions/runs/38213061361) and [push CI 38213057506](https://github.com/HodeTech/Tyrne/actions/runs/38213057506) are service-summary evidence fetched by the coordinator, not this reviewer's independent retrieval or runtime execution. No B-head performance run is claimed. The retained 50ab snapshot remains evidence for its original source only; its file digest is not authentication of the service archive. + +## Documentation + +**Historical reconciliation is substantively sound, with the Low p99 caveat and one label-attribution correction below.** The T-033 mapping matches actual R1 sections 3–7 and distinguishes verdict/procedure/checklist sections 1/2/8. It adds discoverability without replacing the original source-bound verdict or the later WFI/spin correction. The ADR-0040 approval follow-up actually uses the dedicated approval skill's verdict/audit/findings/AC/gates/process shape; the skill mandates no separate storage folder. Index clarification is sufficient; inventing a retroactive code-review format requirement would be wrong. + +The T-030 security report itself names R1 `8437158..364b746` and R2 `8437158..5cd9ee8`; the previous index's cumulative summary was not a false R1 range. New explicit ranges are clearer. A R1's MP-33 and A R2's MP-1 both label the additional allocation-exhaustion check after 32 standard items; old reports are not rewritten. The security master plan contains the extra requirement, and the reports supply their labels. + +**R1-INT-01 — Low, nonblocking: label attributed to the wrong source.** New reconciliation `docs/analysis/reports/2026-10-12-pr-48-supplied-review-reconciliation.md:74` says “`MP-1` in the security master plan.” The actual master plan has an unnumbered allocation-exhaustion bullet at line 68 and contains no `MP-1` label; that label occurs in later review artifacts, including A R2 and T-030 R2. Reproduce with `rg -n MP-1 docs/analysis/reviews/security-reviews/master-plan.md` (no match) and read its kernel-mode list. The equivalence to historical MP-33 and total of 33 dispositions are correct. Change current prose to attribute MP-1 to later review artifacts and identify both labels as referring to the same unnumbered master-plan addition. Preserve original reports. This is source-attribution precision, not a missing review item or new governance rule. Open at immutable 5816c934. + +The fault token in current T-034 notes now matches `tools/smoke.sh` and the BSP standard's `Undefined Instruction`. Its four-check opening snapshot is distinguished from current six-check policy. T-035's new row and current/phase/task-index links identify B as implemented but awaiting both fresh rounds. The historical internal `ci-nightly` title remains appropriate for an exact-byte downloaded snapshot; filename context does not silently rewrite generated evidence. Metadata minimization applies to new ordinary report fields, with arbitrary tool output, auxiliary artifacts and old captures explicitly excluded from any universal sanitization claim. + +## Integration + +The six exact contexts/app binding 15368, strict checking, admin enforcement false, zero approval count and disabled code-owner requirement match committed JSON. No policy or production adapter bytes change. B correctly separates producer-app identity from workflow content/revision integrity. [GitHub's protected-branch reference](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches) supports the admin exception, source-app selection and duplicate-job ambiguity; the supplied specific instant-success duplicate-name bypass was neither reproduced nor established here. The adapter's duplicate evidence refusal must not be confused with GitHub's merge behavior. No new CODEOWNERS, environment, ruleset or acceptance decision is made. + +The [official cache reference](https://docs.github.com/en/actions/reference/workflows-and-actions/dependency-caching) supports PR merge-ref isolation from base/sibling PR caches and reuse by the same PR's reruns. Source inspection separately establishes the actual path/key/prefix choices. Existing registry/git/target build inputs remain a trust boundary. Per-ref cancellation and 10/15-minute smoke/ARM limits are real, but they do not cap separate PRs; organization approval or billing settings are neither claimed nor verified. + +The official [protection endpoint](https://docs.github.com/en/rest/branches/branch-protection#get-branch-protection) and [branch endpoint](https://docs.github.com/en/rest/branches/branches#get-a-branch) document different shapes.

This is an agent verdict, not maintainer sign-off. +- **Date:** 2026-10-12, Europe/Istanbul. +- **Risk class:** Ordinary documentation, workflow comments and generated report prose. The substantive A assurance changes have distinct historical code/security reviews; this B delta changes no runtime, policy or administrative behavior. +- **Security-review cross-reference:** N/A for a new B security pass. Complete prior A security [R1](../security-reviews/2026-10-12-pr48-tools-followup-r1.md) and [R2](../security-reviews/2026-10-12-pr48-tools-followup-r2.md) are scoped historical context, not reused B approval. +- **Requested model/effort:** `gpt-6-astra`, high effort, fresh `fork_turns=none` was supplied as orchestration configuration metadata; it is not independently attested runtime model identity. +- **Scope:** all 15 changed files, 454 insertions and 28 deletions: 13 Markdown files, full-line YAML comments and five replacement shell echo lines. This complete provisional report is written before waiting for the independent peer; final cross-read follows separately. + +## Correctness + +**Zero new findings. Both B Round 1 Low findings are resolved at immutable 646ba33.** The entire cumulative scope was inspected afresh, including the original B corrections and the R1 publication/correction commit. + +- **PR48-CR-01 resolved:** `tools/perf-harness.sh:569–573` now states the nearest-rank fact: at 100 samples the selected rank is 99; from 100 onward it is below the final rank, while ties may still equal the maximum. It explicitly denies statistical reliability from that transition alone and asks readers to use sample count and measurement context. Integer nearest-rank reasoning supports these statements. The changed shell region replaces two literal `echo` lines with five; all other harness bytes, including calculation, valid-sample threshold, watchdogs, output tables and overwrite refusal, remain identical. This corrects an interpretation claim, not a numeric estimator or performance policy. The dated reconciliation caveat explicitly supersedes the inherited historical sentence while preserving all captured report bytes. The exact-source hosted 646 report visibly contains the corrected paragraph. +- **R1-INT-01 resolved:** reconciliation line 74 now attributes MP-1 to later review artifacts and MP-33 to some earlier artifacts. The security master plan's kernel-discipline list has an unnumbered typed-allocation-exhaustion requirement; its source contains neither literal label. Full A R1/R2 reports and relevant T-030 passages establish their shared meaning after the 32 standard items, for 33 total dispositions. No historical checklist or verdict is rewritten. +- **Guide commands and gate counts:** both coverage examples exclude BSP and both userland crates, matching the real workflow. Plain repository-local Cargo selects `nightly-2026-01-15`; explicit `+stable` remains distinct. ARM order is check, clippy, private arch-only rejection probe, native test, Miri setup, Miri test. Four gates correctly means check/clippy/test/Miri, with two supporting operations. Only BSP is excluded from the ARM commands. The fast-lane table now names all four fixture families actually invoked. +- **Timing, cache and setup claims:** Miri's 1–2 minute duration is explicitly observed, not guaranteed; parent-acquired exact 646 summaries show 68/76 seconds and earlier 5816 summaries show 92/85 seconds. All exact cache keys include OS, architecture, toolchain identity and lockfile hash; restore prefixes omit that hash while retaining OS/architecture/toolchain. The stable lane's identity is the rolling stable channel, not an immutable compiler. Actual path lists omit cargo-bin, while registry/git/target remain trusted build inputs. Each workflow repeats installation/cache setup directly; no shared composite action is present. Monday 03:17 UTC matches the cron expression. +- **Policy and boundary truth:** six required display names, app ID 15368, strict checking, admin enforcement false, approval count 0 and code-owner review false match committed policy. The guide distinguishes producer identity from workflow/source integrity, and GraphQL review enablement from REST approving count. The supplied instant-success duplicate-name bypass is not established. Duplicate names can produce ambiguity; no hosted bypass experiment is claimed. No new CODEOWNERS, environment, ruleset, approval or admin-enforcement policy is adopted. +- **Capacity and response shapes:** per-workflow/ref cancellation does not cap separate PRs. Smoke/ARM have 10/15-minute bounds; organization billing/approval/capacity controls are expressly unverified. The captured REST response is dated observed-shape coverage, not permanent live equality or universal compatibility. Normalizer tests preserve the complete policy and refuse unknown enforcement/actor and branch-summary extensions. Source inspection confirms narrow metadata stripping, strict fields, independent GraphQL/ruleset reads and non-atomic reread/PATCH/readback. B does not change these paths or claim atomicity. +- **Smoke and history:** T-034 uses the actual `Undefined Instruction` token matching source and fixtures, without claiming exhaustive CPU-fault or exact SVC coverage. Its original four-check count is marked as an opening snapshot against current six-check policy. T-033's five-role map matches original numbered headings and is strictly additive. T-030's index names both actual review ranges. The ADR-0040 artifact remains an approval review using its dedicated template; indexing it here does not invent a different review type. + +## Style + +**Clean.** New prose is English with normal word/number spacing and stable exact tokens. UTC-only wording is an ordinary simplification; the UN's English-language use of the official country name refutes the supplied language-violation allegation. Workflow comments describe present behavior without changing YAML execution. ShellCheck 0.11.0, actionlint 1.7.12 on both explicit workflow paths and immutable-range whitespace validation pass. + +Both cumulative commits use Conventional Commits, explain the scope and cite existing ADR-0013/0040. R1 review trailers point to real artifacts and do not pretend to approve subsequent bytes. There is no Rust style, unsafe annotation, diagram or dependency addition needing separate treatment.

Production kernel, HAL, BSP, userland, unsafe regions, ADRs and live policy are unchanged by this delta. +- **Security-review cross-reference:** `/tmp/tyrne-pr48-tools-r1-security.md`, fresh distinct round-1 pass; publication under the canonical security-review folder belongs to the coordinating author. +- **Scope:** follow-up A only: captured REST protection fixture and conservative boundary tests; exact-command clean ARM baseline before the six-cfg negative; empty-diagnostic refusal; actual Undefined Instruction smoke token; optional performance metadata fallbacks and minimization of override paths/hostname; five cargo-bin cache-path removals. Remaining supplied-report documentation work is follow-up B and is neither approved nor required prematurely here. + +## Correctness + +- **ARM baseline attribution — pass.** `tools/test-ci-gates.sh` defines one `ARM_COMMAND` array: `cargo clippy --workspace --exclude tyrne-bsp-qemu-virt --all-targets -- -D warnings`. The same array executes on the unmodified private copy and after exactly six hello cfg gates are changed from `all(target_arch = "aarch64", target_os = "none")` to arch-only. The build script and syscall shim are copied unchanged. Any clean-baseline failure stops before mutation. The negative must return compiler exit 101 and contain an exact complete line for duplicate `panic_impl` or unsupported unwinding without std. Empty diagnostics, unrelated/near-match lines, successful commands and tool-failure exits are refused. This makes the second diagnostic attributable to the intentional source change given the successful same-command control; it does not establish a universal classifier for every Rust failure. +- **ARM isolation — pass.** Host verification precedes cargo; temporary tracked-source copies use NUL-safe filenames, a private target and cleanup traps. Fixtures verify originals remain byte-identical, source paths with spaces work, calls occur clean then mutated, malformed anchors cause no cargo invocation, and refusal paths clean up. Independent actual Apple ARM execution passed with the negative returning 101/E0152. +- **Protection fixture — pass.** No production normalizer or write path changes. The complete captured protection-endpoint response normalizes to the entire committed definition, including six app-bound checks and non-status policy. A new independent read-only GET at API version `2022-11-28` exactly matched the parsed fixture. Branch-summary `name`/`protection_url`, enforcement scope, and review dismissal/bypass actor extensions remain unrepresentable and refused. This fixture does not authorize ignoring new policy fields. +- **Smoke fault token — pass.** `tools/smoke.sh:151` now matches QEMU's actual `Undefined Instruction` class. Both debug and release synthetic cases retain all required markers while injecting each of six fault classes, so success cannot hide the fault. The production profile requirements and intentional SVC handling are unchanged. +- **Performance metadata — pass.** `tools/perf-harness.sh` keeps completed measurements when `uname`, QEMU version, `rustc -V`, or active-toolchain discovery fails, recording `(unknown)` and suppressing failed-command output. The active rustup toolchain identifier is retained while its override explanation is removed; `uname -srm` excludes the hostname. Valid/failed sample accounting, percentile calculation, watchdog behavior and overwrite refusal remain intact. This is minimization of these normal metadata fields, not a claim to sanitize arbitrary successful tool output or all diagnostic artifacts. +- **Cache paths — pass with one Low wording finding.** Five `~/.cargo/bin` cache entries are removed while registry/git/target caches, architecture keys and installation steps remain. Exact-head hosted runs completed successfully. The remaining coverage comment still contrasts itself with sibling jobs; see R1-SEC-01 below. + +**Blocking correctness findings:** none. + +## Style + +ShellCheck 0.11.0 over all `tools/*.sh`, actionlint 1.7.12, and immutable-range `git diff --check` passed. Naming, quoting, Bash arrays, explicit Python exceptions and focused fixture helpers are consistent with the surrounding tooling. No Rust style/unsafe exception is introduced.

It passes at the reviewed head. The initial mistyped unittest class selector produced a loader error and was discarded; it is not counted as regression evidence. +- The 20-case new smoke suite rejects the old script at `debug-fault-5`: expected fault exit 1, observed exit 0. At the reviewed head both debug and release Undefined Instruction cases pass. Synthetic evidence is explicitly distinguished from actual guest execution. +- An isolated metadata control used the new fixture helper and a uname stub accepting both argument layouts, to avoid confounding metadata fallback with the separate `-a` to `-srm` change. For each of rustc/rustup/QEMU and exit 1/127, head bytes retained three valid samples, emitted one report with unknown metadata and no failure-output canary; old bytes exited 1/127 and emitted no report. The original whole new test also rejects old bytes, but its strict new uname stub can fail first with 64; the isolated control supplies the causal fallback evidence. +- No before/after failure is expected for the new REST fixture: the implementation deliberately stays unchanged, and the new coverage pins an observed shape without weakening conservative refusal. + +### Hosted exact-head integration evidence + +Read-only `gh run view` independently confirmed completed `success` and exact head `50ab72bf2c15a4d34be25a1491a357313e50390a` for all three runs: + +| Run | Event and result | +|---|---| +| [38210439123](https://github.com/HodeTech/Tyrne/actions/runs/38210439123) | PR CI; all seven jobs success, including ARM, QEMU, Miri, nightly/stable host, kernel and informational coverage | +| [38210436230](https://github.com/HodeTech/Tyrne/actions/runs/38210436230) | Development push CI; all seven jobs success | +| [38210436174](https://github.com/HodeTech/Tyrne/actions/runs/38210436174) | Development push performance validation; report job success | + +Downloaded artifacts were fetched by the coordinating author; this reviewer independently inspected the extracted report, production smoke outputs and parsed probe results.

Production debug/release outputs reach userspace exit and all-tasks completion with the expected profile console contract and no configured fault class. The new Undefined Instruction cases are present. This reviewer did not independently download/recompute the service archive digest or rebuild those three hosted mutant kernels. + +The downloaded performance report identifies clean full source, pinned compiler/toolchain, QEMU 8.2.2, 20 valid/0 failed samples, and a 100-second full harness run. This reviewer recomputed nearest-rank p10/p50/p90 from its 20 raw samples: `5,232,672 / 5,473,392 / 7,277,776 ns` (`5.233 / 5.473 / 7.278 ms`). Report SHA-256 independently matches `24c143abb0151de1eb3fb38ff3d74f3e060effd2a6c492cc8389bebca565ae85`. The report retains the toolchain identifier and omits the usual override path and hostname. These are informational QEMU measurements, not a calibrated performance gate or hardware benchmark. + +**Missing tests that block this delta:** none. A real Undefined Instruction mutant guest is not claimed; the actual token matcher is exercised directly by controlled trace fixtures and positive actual guest integration remains covered. First merged-main and default-branch-only dispatch evidence remains pending maintainer merge. + +## Documentation + +The fixture README states endpoint/API-version provenance and conservative representability boundaries. The ARM guide explains the identical-command clean baseline and bounded negative acceptance. T-034/T-035/T-036 append the new evidence while retaining `In Review`; no agent Done promotion or ADR revision occurs. + +**R1-SEC-01 — Low, nonblocking, independently corroborated:** `.github/workflows/ci.yml:438` still says cargo-bin is omitted here “unlike the sibling jobs.” This delta removed cargo-bin from those sibling caches, so that contrast is stale. Update the comment to describe the current all-job behavior. Root has assigned this to the A round-1 correction before round 2. At immutable `50ab72b` it is still open; this review does not certify the future correction. It is one shared finding, not an additional independent defect count. + +The supplied report's remaining prose, examples, historical token references and claim corrections are explicitly allocated to follow-up B. Their absence from A is not a new A blocker, and this review does not clear them. The post-fix token sweep found the old fault token in pre-existing task prose and the newly stale sibling-cache comment; the two have distinct scope dispositions. ADR-0040's implementation policy and the `Refs: ADR-0040` trailer govern this change. No new public Rust item or unsafe contract requires rustdoc or an audit amendment. + +## Integration + +Prerequisites were read directly, with bounded output and recovery of initial truncations: AGENTS, complete CLAUDE and current roadmap, all 39 existing numbered ADR files in numerical order (0034 is reserved and absent), and all 15 files under standards including the index. The `perform-code-review` and `conduct-review` skills and complete code-review master plan/template were read. The supplied attachment and read-only PR body establish intent; test changes were read before implementation.

No unresolved code/security verdict conflict or additional blocker was found. Both reports keep R1-SEC-01 open at exact 50ab and require fresh verification of the forthcoming correction.

This publication commit replaces the stale sibling-cache contrast with the current explicit-install/all-cache-bin-omission comment.

Fixtures verify clean→mutated order, failure stopping before mutation, wrong statuses, success, unrelated/near-match diagnostics, host/anchor/copy/CLI refusal, original-byte preservation and cleanup. This establishes the intended controlled regression assertion under trusted tools, not general compiler-output authenticity or exclusion of every possible external coincident failure. +- **Smoke fault detection:** `tools/smoke.sh:151` and `tools/test-smoke-gates.py:21` now use the producer's actual `Undefined Instruction` token, consistent with the BSP standard. Both profile fixtures retain the success markers while adding the fault; both reject it. Existing marker and release-greeting contracts are preserved. This is a specific matcher correction, not exhaustive CPU-fault detection or an adversarial-EL0/runtime-safety proof. +- **Performance reporting:** `tools/perf-harness.sh:251–264` treats failed uname/QEMU-version/rustc/rustup discovery as unknown metadata, discarding failed partial stdout and suppressing stderr. Normal rustup override explanation is removed while the toolchain identifier remains; `uname -srm` omits hostname. Failed measurements still fail the existing threshold; optional metadata does not turn them into success. Sample accounting, watchdog/statistics, source-state attribution and append-only report refusal remain intact. Minimization applies to normal metadata fields, not arbitrary successful output from hostile/custom tools or every auxiliary artifact. +- **Protection response coverage:** `tools/test-branch-protection.py:105–125` normalizes the complete captured protection-endpoint fixture to the entire committed policy and separately refuses summary/enforcement/review-actor extensions. Production adapter and policy definition are byte-unchanged. The dated fixture is observed-shape coverage, not future live-policy equality, permission to drop policy-bearing fields, or administrative write authority. +- **Cache changes:** five cargo-bin cache paths are removed while explicit installations, registry/git/target paths, architecture keys, action pins and token permissions remain. The coverage comment now accurately states all CI caches omit cargo-bin. Existing generated build-cache trust is not eliminated by this change. + +## Style + +**Findings: none.** ShellCheck 0.11.0, actionlint 1.7.12 against both explicit workflow files, and immutable-range whitespace checking pass. Quoting, Bash arrays, focused fixture helpers and explicit exception checks fit existing tooling. The corrected YAML comment's indentation has no semantic effect and is understandable; it is not a substantive style defect. No Rust style or unsafe exception is introduced. + +## Test coverage + +### Independent exact-source execution + +Extracted `git archive 683965b5aa2f5da2e11429aa42803bb3a5fa6f60` into a private temporary tree.

This is an informational QEMU band; no calibrated regression or hardware-performance verdict. Service artifact-archive digest was not independently recomputed. Perf harness, performance workflow, smoke and ARM probe bytes are identical between 50ab and 683965b; this supports relevance of earlier scoped behavioral evidence but does not relabel it as a 683965b performance run.

This code review does not substitute for that pass or certify kernel/assembly soundness. +- **Procedure:** `perform-code-review`, `conduct-review`, complete code-review master plan; all five roles completed sequentially. `propose-standard-change` read to audit governance. Task intent and actual release-only tests were read before the executable diff; guard/probe helpers and Cargo configuration before workflow callers and downstream documentation. Parent explicitly requested a read-only temporary report: canonical publication, review index, task history and any commit/trailer reconciliation remain parent-owned. + +### Correctness + +**No actionable finding.** The new gate closes the specific vanishing-test hazard without changing the syscall mechanism. + +The existing ABI release test asserts that number 5 decodes to `None`. The dispatcher release test supplies a valid console capability but expects `BadSyscallNumber` and an empty console capture. Both compile only with `not(debug_assertions)`. They establish the intended release contract at two layers; neither merely checks a source string or restates the guard parser. + +`check-release-tests.sh` selects only the kernel library target and both named filters. It requires each fully qualified test's exact successful line and the `2 passed; 0 failed;` summary. Thus zero selected tests, one missing test, an ignored test, a test with an incorrect module-qualified name, additional passing tests, or failure summaries cannot satisfy the gate. Cargo and `tee` run inside a `set -euo pipefail` pipeline, so a command failure cannot be hidden by the output parser. The unpredictable temporary log is removed by EXIT cleanup. The real run succeeded with exactly two tests; controlled Cargo exit 42 propagated even when stdout contained both successful names and a perfect two-pass summary. + +`test-ci-gates.sh --release` reuses the existing tracked-current-worktree snapshot and rejection contract. The profile insertion occurs only in the private copied manifest. The probe runs the canonical script, requiring both a nonzero guard status and its specific failure diagnostic. Cargo compilation/tool failures without that diagnostic are not accepted as profile-regression proof. The copied toolchain/configuration selects the repository's pin; its sibling private Cargo target prevents shared cached artifacts from certifying the mutation. Independent controlled inspection verified exactly one `debug-assertions = true` insertion under the release table, the exact Cargo argument vector, private cwd/target, no `.git` or untracked `hello.bin`, and removal of the private root afterward. The actual isolated profile-flip probe passed by observing guard exit 1. + +Both aliases preserve target and package selection and add only `--release`. The production fast lane runs full release host tests before the named guard and negative probe. None uses `continue-on-error` or unconditional success. The kernel job performs existing debug work first, builds release userland before release kernel build/clippy, then restores debug userland immediately before the final debug perf-bench build and lint. The perf Cargo features appear before the clippy `--` separator. No flags are appended after the existing alias's rustc delimiter. + +The shared image boundary is explicitly handled. `build-userland.sh` writes one profile-dependent `hello.bin`; BSP `build.rs` checks existence and watches changes but cannot establish the image's profile. The workflow restores the correct image at the precise boundary. Hosted logs independently inspected here show 117-byte debug → 69-byte release → restored 117-byte debug, followed directly by successful dev-profile perf build/lint. This is compile coverage, not release guest execution. + +The only Rust delta splits three imports under `#[cfg(debug_assertions)]`: `CONSOLE_WRITE_CHUNK`, `MappingFlags`, and `FakeUserMem`. Reference and enclosing-test cfg inspection matches those gates. Shared fixtures and imports needed by the release test stay unconditional. No test assertion or production function changes. The independently compiled release kernel library confirms the scoped imports remain sufficient in that profile. + +### Style + +**Clean.** Independent default-severity ShellCheck 0.11.0 over `tools/*.sh`, full actionlint 1.7.12, Bash syntax checks, and range whitespace checks pass. The real and controlled scripts execute under macOS `/bin/bash` 3.2.57. Paths containing spaces and glob metacharacters were used in controlled checks. Script modes are executable; existing snapshot copying preserves modes. No new lint suppression, warning relaxation or unnecessary dependency appears. + +All three range commits use Conventional Commits, English messages and valid `Refs: ADR-0040` trailers. Implementation also references ADR-0031 and ADR-0039. The existing Accepted ADR precedes the standards commit. No new unsafe audit record is required by an import-only test delta. Separate security review publication/trailer handling remains parent-owned. + +### Test coverage + +Independent checks performed in this fresh review: + +| Check | Observed result | +|---|---| +| Real `tools/check-release-tests.sh`, separate temporary Cargo target | Exit 0; both exact tests pass, 2 passed / 0 failed / 247 filtered | +| Real `/bin/bash tools/test-ci-gates.sh --release` | Harness exit 0; intentional profile change rejected by guard exit 1 and expected diagnostic | +| Controlled valid two-test output | Exit 0, temporary log removed | +| Controlled zero-test / vanished output | Exit 1, cleanup verified | +| Controlled missing ABI test | Exit 1, cleanup verified | +| Controlled missing dispatcher test | Exit 1, cleanup verified | +| Controlled incorrect fully qualified name | Exit 1, cleanup verified | +| Controlled ignored test | Exit 1, cleanup verified | +| Controlled failed summary | Exit 1, cleanup verified | +| Controlled three-pass summary | Exit 1, cleanup verified | +| Controlled Cargo exit 42 with perfect successful test output | Exit 42 propagated, cleanup verified | +| Controlled private profile-flip snapshot and exact command inspection | Correct manifest mutation, cwd, target and argv; no `.git`/`hello.bin`; complete private-root cleanup | +| ShellCheck over every tooling script | 0.11.0; exit 0 at default severity | +| Full actionlint | 1.7.12; exit 0 | +| Changed scripts `/bin/bash -n` | Exit 0 | +| `git diff --check 8437158..364b746` | Exit 0 | +| Changed Markdown relative file targets | 257 references resolve; code examples excluded; not an exhaustive historical-anchor claim | +| Final branch/worktree check | `development`, clean, HEAD `364b74626d54fffd5a73d6bec833877308eb5285` | + +Controlled probe source is `/tmp/tyrne-r1-code-probes.py`. The first isolation assertion compared macOS `/var` and `/private/var` path spellings literally and failed in this review fixture; resolving both paths corrected the fixture. The corrected run completed every assertion above. This was not a repository defect or an accepted failed verification. + +Root separately supplies local fmt, host clippy, 366 debug and 356 release host passes, debug/release kernel build/clippy, userland clippy, perf build/lint, 59 QEMU argument fixtures, 366 Miri passes with no UB failure and existing warnings, seven additional controlled guard outcomes, and restored debug image hash `05816ccb9be5caea862dbe3e0fc45fc2068ff06cd049f2dda3459492d0ef7d88`. Those are attributed implementation results, not all independently repeated here. The new guard's real private-target compilation and targeted adversarial checks address the highest-risk changed contract directly. No new production behavior or unsafe invariant needs an additional Rust test in this delta. + +### Documentation + +**No actionable finding.** The task criteria and review history distinguish the opening baseline, isolated reproducer, local implementation, and first hosted green. The 356 release count correctly excludes two ignored HAL doctests and differs from 366 debug passes. Local warm 1.49 s and hosted 13 s are labeled separately as build/test wall time, not guest-performance measurements. + +The CI job/local-command tables, workflow header and three downstream standards now name release host coverage, the explicit named-test assertion, profile-flip rejection, release kernel build/clippy, and debug perf build/lint after image restoration. The QEMU guide documents both release aliases and the need to restore debug userland afterward. The task and guide explain why Cargo zero-test success is insufficient. T-034 retains ownership of release EL0 runtime enforcement; no current compilation or agent result is presented as hosted guest coverage. + +This implements Accepted ADR-0040 and ADR-0039's explicit matching-image pipeline. Standards are minimally updated after the motivating ADR; no Accepted decision is reversed, no new architecture choice is introduced, and P1–P12 need no amendment. The downstream testing/release summaries are updated along with infrastructure, avoiding the discrepancy found during T-031. All three live current-focus pointers, task and task index agree on T-030 `In Review`, implementation gates passed, fresh review rounds pending. Historical dated banners remain history. No premature Done or final-PR/merged-main claim occurs. + +### Integration + +The existing required job display names, triggers, least-privilege permissions, action SHAs, workspace default-members and Rust pin remain unchanged. The added checks are within already required jobs. The host command omits the bare-metal BSP as intended through `default-members`; the BSP has separate target-aware compilation/linting. The copied release probe reads the same pin and canonical guard. Positive commands run before their expected-failure probes; a deliberately rejected mutation counts as a successful harness, not a failed production workflow. + +Direct inspection of parent-downloaded `/tmp/tyrne-b21-step4/hosted-run.json` associates [run 38179424325](https://github.com/HodeTech/Tyrne/actions/runs/38179424325) with exact executable/standards head `c716ae3d312b1a6213ec35346a87940a79af3465` and success in all five jobs.

Read the complete prior preflight and T-031 review artifacts; full T-030 task, approved eight-step sequence/index context, actual release tests and adjacent fixtures/cfg references, both new/extended scripts, complete executable range diff, Cargo configuration/manifests, userland image helper, BSP build script, full workflow and CI guide, changed QEMU guide/standards/status/task portions, all three commit descriptions, and relevant parent-fetched hosted metadata/log evidence. + +No claim to reread the entire unchanged syscall dispatcher, userland/assembly implementation, unrelated task backlog, or every historic anchor. No shared image or kernel ELF write, alternate-profile shared build, independent Miri/stable/full-host-suite rerun, guest smoke, SMP/hardware test, performance study, signal/kill stress test, repo edit, branch mutation, commit or GitHub mutation. Normal and guard-error cleanup were exercised; hostile termination cleanup is not claimed. Known T-038 asm debt remains outside this review and cannot be disproved by lint/test success. + +### Verdict + +**Approve T-030 at `364b746` for this fresh Round 1 code review; no actionable findings.** All five axes and the standard checklist are complete. Real guard/profile-flip checks, adversarial parser/error/isolation verification, and the attributed hosted results support the scoped implementation. Separate security review, the second fresh round and final maintainer PR remain required. This verdict does not promote Done, authorize a merge, certify kernel soundness, or claim release guest coverage. + +## Round 2 code review + +- **Change:** approved Track B.2-1 step 4, T-030 on `development`, `8437158..5cd9ee8a01ac523e48146e2224284b871e3619ab`. Implementation `b8ad56f`, downstream standards `c716ae3`, hosted evidence `364b746`, Round 1 records `5cd9ee8`; 18 files, 410 additions / 33 deletions including review records. +- **Reviewer:** fresh independent delegated agent `/root/b21_step4_round2_code`, acting on behalf of @cemililik. Parent requests `gpt-6.1-sol`, high reasoning, `fork_turns=none`; these are requested orchestration settings, not an independently attested runtime model identity. +- **Date:** 2026-10-12, Europe/Istanbul; hosted timestamps cited below are UTC on 2026-10-11. +- **Risk class:** security-sensitive context: CI enforcement of the release syscall surface and test-only imports in a syscall module. Production syscall logic, authority, assembly, unsafe bodies and safety arguments are unchanged. +- **Security-review cross-reference:** existing distinct [Round 1 security review](../security-reviews/2026-10-12-t030-release-gates.md) covers the same executable delta. A distinct fresh Round 2 security pass is commissioned separately by the parent and must be reconciled before the step's two-round lifecycle is complete. This report is the code pass only. +- **Procedure:** `perform-code-review`, `conduct-review`, full code-review standard/master plan; five roles executed sequentially. `propose-standard-change` also read to audit standards governance. Task and actual release tests read first, then Cargo/profile prerequisites and guard/probe implementations, workflow callers, downstream documentation and review records. Parent owns canonical publication, review index, task history and any commit/trailer updates; no repository or GitHub mutation was performed here. + +### Correctness + +**No actionable finding.** The implementation fulfills the narrow release-verification contract without modifying the production mechanism it protects. + +The existing ABI test asserts `SyscallNumber::decode(5) == None` under `not(debug_assertions)`. The dispatcher test grants a valid `DebugConsole` capability with `CONSOLE_WRITE`, calls the ordinary dispatcher and requires both the precise `BadSyscallNumber` status and empty console output. This is meaningful despite its empty user window: an accidentally exposed console handler would return a different address error, rather than the required number rejection. Both tests disappear when release debug assertions are enabled; merely running Cargo with their filters cannot establish their presence. + +`tools/check-release-tests.sh` selects the kernel library and the two named filters, requires the exact fully qualified successful test line for each, and requires a `2 passed; 0 failed;` summary. Independent real execution in a private tracked snapshot observed both passes and 247 filtered tests. After the isolated release profile flip, the exact raw Cargo command returned exit 0 with zero tests and 259 filtered tests, while the canonical guard returned exit 1 with its specific missing-test diagnostic. This directly reproduces the hazard and verifies its correction. + +The evidence parser has the intended scope. Zero matches, either required name missing, a wrong module-qualified name, a required test ignored, a failing summary or a third passing matching test cannot satisfy it. Two required passes plus an additional ignored matching test do satisfy it; the contract proves two passes, rather than banning every possible third match. The script relies on the pinned toolchain's ordinary libtest text format; formatting drift fails closed. The guard is regression detection within a trusted source/compiler environment, not authentication against fabricated compiler/test output. + +`set -euo pipefail` keeps a failing Cargo command or `tee` from becoming a green guard. A controlled Cargo stub that emitted a perfect successful transcript and then exited 42 caused the guard to exit 42. The unique `mktemp` log is quoted throughout and removed on normal success and tested error paths. Invalid script arguments return 2 before log creation. Controlled runs used Bash 3.2 and paths with spaces, and verified the exact Cargo argument vector and temporary-log cleanup. + +The extended `test-ci-gates.sh --release` inserts `debug-assertions = true` only beneath `[profile.release]` in its private tracked-current-worktree copy. Its preexisting copy loop uses NUL-delimited tracked filenames and preserves executable modes. The copied pin/configuration and fresh private Cargo target prevent certification by the checkout's old release executable. The `run_negative` helper requires both nonzero status and the guard's fixed diagnostic: an unrelated compiler failure alone cannot pass it. Independent execution of the actual repository harness succeeded by observing guard exit 1, and its private directory was absent afterward. The source manifest remained unchanged. + +The release build/run aliases preserve the debug aliases' target/package selections and add `--release`. Full host release tests are a separate blocking step before the narrow guard and negative probe. The existing `default-members` restrict that host command to kernel, HAL and test-HAL, while the bare-metal BSP has its own target-aware build/lint steps. + +The kernel job's profile transitions are correct and explicit: existing debug image/build/lint; matching release userland, release kernel build and release clippy; restored debug userland immediately before debug `perf-bench` build and clippy. Cargo's feature/target/package flags remain before the clippy `--` delimiter. No new gate has `continue-on-error` or unconditional success handling. `build-userland.sh` writes one profile-dependent `hello.bin`; BSP `build.rs` checks presence and watches changes but does not verify the profile. Therefore the restore step is load-bearing. Source order and inspected hosted logs agree on 117-byte debug → 69-byte release → restored 117-byte debug before final dev-profile perf work. These are compilation/lint claims, not guest execution claims. + +The entire Rust delta scopes three test imports with `cfg(debug_assertions)`: `CONSOLE_WRITE_CHUNK`, `MappingFlags`, `FakeUserMem`. Their test references are in existing debug-only tests; common release fixtures and imports remain available. Independent real release and debug test compilation passed. No production function, test assertion, syscall number, capability, unsafe operation or audit reasoning changes. + +### Style + +**Clean.** Independent default-severity ShellCheck 0.11.0 over all `tools/*.sh`, actionlint 1.7.12 over the workflow, `/bin/bash -n` on both changed scripts and range whitespace checks all pass. No lint relaxation, suppression, new dependency or refactor unrelated to T-030 appears. The guard is executable; snapshot copying preserves executable permissions. Comments, diagnostics, documentation and four commit messages are English. + +All four commits have intelligible Conventional Commit subjects and valid ADR references. The implementation names ADR-0040/0031/0039; the standards commit follows the already Accepted governing ADR. Round 1's follow-up records both code/security references and explicitly does not fabricate a retroactive trailer on the initial implementation. An import-only test edit creates no unsafe audit obligation. The final maintainer PR and this round's publication/trailer reconciliation remain parent-owned. + +### Test coverage + +**Adequate for the declared delta; no missing blocking test.** The highest-risk changed behavior was independently executed, including the real regression and actual negative harness. Broad unchanged checks are attributed below rather than represented as freshly repeated. + +Independent commands and fixtures in this round: + +| Check | Result | +|---|---| +| Real guard in private tracked snapshot / private Cargo target | Exit 0; both exact release tests pass; 2 passed / 0 failed / 247 filtered | +| Exact raw narrow Cargo command after private release profile flip | Exit 0; 0 passed / 0 failed / 259 filtered; original hazard reproduced | +| Real guard after that same flip | Exit 1; zero tests and required guard diagnostic | +| Real debug ABI contract after restoring private manifest | Exit 0; debug console-number test passes; 1 passed / 258 filtered | +| Actual repository `tools/test-ci-gates.sh --release`, private temporary root | Harness exit 0; deliberate regression rejected at guard exit 1; private probe tree cleaned | +| Controlled valid two-pass evidence | Exit 0 | +| Controlled zero tests | Exit 1 | +| Controlled missing ABI test | Exit 1 | +| Controlled missing dispatcher test | Exit 1 | +| Controlled wrong fully qualified ABI name | Exit 1 | +| Controlled required test ignored | Exit 1 | +| Controlled third passing matching test | Exit 1 | +| Controlled required two passes plus extra ignored match | Exit 0; intentional acceptance | +| Controlled failure summary | Exit 1 | +| Controlled Cargo exit 42 after valid successful transcript | Exit 42; pipeline failure preserved | +| Unexpected guard argument | Exit 2; usage diagnostic | +| Exact Cargo argument vector / temporary gate-log cleanup | Asserted for every controlled Cargo case; cleanup passed | +| ShellCheck 0.11.0, actionlint 1.7.12, Bash syntax, range whitespace | All exit 0 | +| Changed Markdown relative links and heading anchors | 295 relative references, including 26 heading fragments; all resolve | +| Read-only GitHub run metadata for exact reviewed HEAD | All five jobs successful; release/probe/kernel/perf steps successful | +| Branch / worktree / reviewed HEAD | `development`, clean, `5cd9ee8a01ac523e48146e2224284b871e3619ab` | + +Independent test driver: `/tmp/tyrne-b21-t030-r2-code-checks.py`; complete captured results: `/tmp/tyrne-b21-t030-round2-code-checks.json`. Python `tempfile.TemporaryDirectory` owns the snapshot, its Cargo target, fixture binaries and temporary logs; cleanup completed. No shared `hello.bin` or kernel ELF was built or overwritten. The actual harness's own implementation was run unchanged and its cleanup observed. + +One review-fixture correction was necessary: the first documentation-link scanner treated the literal inline-code example `](...)` in a task criterion as a real link. Excluding inline code and fenced examples corrected the scanner; the corrected full scan passed. This was a reviewer fixture false positive, not a repository defect or an accepted failed check. + +Coordinator/task-recorded local evidence separately reports full fmt, host/debug/release/perf/userland clippy, debug/release/perf builds, 366 debug and 356 release host passes, 366 Miri passes with no UB failure and existing warnings, 59 stubbed QEMU argument fixtures, matching image restoration and debug-image SHA-256 `05816ccb9be5caea862dbe3e0fc45fc2068ff06cd049f2dda3459492d0ef7d88`. This reviewer did not rerun that entire suite. This round's independent real tests and controlled failure matrix directly test the changed enforcement contract; no new production behavior or unsafe invariant warrants a duplicate guest smoke here. T-034 retains hosted release EL0 runtime enforcement. + +### Documentation + +**No actionable finding.** The task, CI guide's job/local command tables, workflow header and infrastructure/testing/release standards describe the implemented release host tests, exact named execution assertion, isolated profile-flip rejection, release kernel build/clippy and restored-debug perf build/lint. The QEMU guide provides the two release aliases with a matching-userland prerequisite and an explicit restoration instruction before returning to debug. The new command is documented at the script header and in the guide. + +The task's recorded totals are correctly 249 kernel + 46 HAL + 58 test-HAL + 3 doctests = 356 release passes, with two ignored HAL doctests excluded. Debug has 366 passing tests. The first hosted release step spans 13 seconds, distinct from the 1.49-second warm local run and from guest performance. Historical task rows retain their point-in-time pending states; the final row and active current-focus/index pointers agree on T-030 `In Review`, first round passed and second round pending. No final-PR, merged-main, Done or hosted release-runtime claim is made. + +Governance is consistent: Accepted ADR-0040 authorizes the CI execution policy; ADR-0030/0031 govern the debug console; ADR-0039 governs the explicit source-built matching-image pipeline. Standards changes are minimal and downstream summaries were updated, with existing references to ADR-0040. No architectural reversal, new policy choice, principle amendment or new ADR is needed. Round 1's parser wording now correctly distinguishes a third passing match from an extra ignored match, independently verified here. Both prior review artifacts preserve T-038's exclusion and honest evidence provenance. + +The corrected link scan covers every changed Markdown file's ordinary inline relative links outside code, including heading targets, and reports no broken link. It is not a whole-repository Markdown parser or an external URL availability audit. + +### Integration + +**Clean within T-030.** No workspace member/default-member, toolchain, lockfile, dependency, third-party action SHA, cache key, workflow trigger, required job display name or permission changes. New checks are ordinary blocking steps in the existing required jobs. Host tests and bare-metal compilation remain target-correct. The negative probe reads the current tracked source and the same canonical guard rather than a historical checkout, and does not commit a broken regression or create an alternate branch. + +Hosted evidence has two explicitly different provenances: + +1. **Independently fetched exact-HEAD metadata.** `gh run view 38180378759 --json headSha,conclusion,status,url,jobs` returned completed/success at exact `5cd9ee8a01ac523e48146e2224284b871e3619ab`, with all five job conclusions successful.

It removes a parser warning without changing QEMU's diagnostic mode. +- Quoted inner prefix expansions in `perf-harness.sh` now treat the repository root literally, including glob characters. An independent Bash 3.2 expression check confirmed this behavior. +- The sole new function-scoped ShellCheck directive suppresses the measured indirect trap callback false positive under the codes used by 0.9.0 and 0.11.0. The three actual trap registrations were inspected. No file-wide suppression was added. +- `test-ci-gates.sh` validates its mode before creating a copy; uses an unpredictable temporary directory; copies current tracked file contents using NUL-delimited paths; preserves script modes; changes only the copy; sets a distinct Cargo target directory; and removes the copy on normal/error exit. Neither negative mode calls the userland image writer. Its tracked copy includes the toolchain and Cargo configuration, so the bare `cargo` invocation selects the same pinned nightly as CI's explicit toolchain prefix. +- Expected failure requires both a nonzero exit and the intended lint diagnostic.

The ephemeral smoke log was `/var/folders/d2/k7c1fj3976g7_qq7113f66p00000gn/T/tyrne-smoke.86664.log`. This is runtime regression evidence, not a timing-performance conclusion. + +The two negative harness modes test actual lint enforcement rather than only source shape. Their additional sensitivity checks cover the dangerous false-green paths. No additional implementation-mirroring test is required for the quoting-only script corrections. + +Hosted evidence is separate from the independent local results above. The superseded [run at `1cb3526`](https://github.com/HodeTech/Tyrne/actions/runs/38177838556) is explicitly a failed workflow: the orchestrator reports hosted ShellCheck 0.9.0 rejected the indirect trap callback as SC2317, while the userland job and its negative probe passed. The task history honestly records that result; `0acf0cd` adds that measured code to the same reasoned suppression. Local 0.11.0 success is not evidence that the superseded hosted run was green. + +The orchestrator subsequently supplied [successful retry 38178035728](https://github.com/HodeTech/Tyrne/actions/runs/38178035728), on full reviewed head `0acf0cdaaf2b8502465d813fa82e0c347a2f70b0`, reporting all five jobs successful. This reviewer did not independently fetch GitHub run metadata. I did directly inspect the root-fetched logs: `/tmp/tyrne-b21-step3/hosted-fastlane.log` records ShellCheck 0.9.0 (line 174), the isolated shell probe rejecting SC2086 with exit 1 (line 184), and all 59 argument cases passing (line 618); `/tmp/tyrne-b21-step3/hosted-kernel.log` records the positive bare-metal userland clippy completion followed by the isolated userland probe rejecting `clippy::clone_on_copy` with exit 101 (line 214). Thus the new gates and both intended hosted failure modes have direct supplied-log support on the corrected head. The metadata success claim remains clearly attributed to the orchestrator. + +### Documentation + +The task, task index and `current.md` consistently retain T-031 as `In Review`; hosted/review requirements are pending in the reviewed snapshot, rather than falsely marked complete. The CI guide and infrastructure standard describe the new package/target command, ShellCheck default severity and version output, both isolated probe modes and the meaning of a passing expected-failure harness. ADR-0040 supplies the governing decision and precedes the standard edit. + +**R1-CODE-01 — Low, non-blocking: reconcile the downstream CI-gate summaries.** `docs/standards/testing.md:105` still states that `host-clippy` plus `kernel-clippy` together cover the workspace, the exact false coverage premise corrected in `infrastructure.md` by this task. Its gate list also omits ShellCheck and the new probes. `docs/standards/release.md:61` still enumerates clippy as those two aliases and omits the new tooling gates. A contributor following these summaries cannot identify the full newly enforced local checks. Update these narrow summaries to the target-aware userland clippy plus ShellCheck/probe gates, or make them defer explicitly to the canonical required-gates list. This is the direct downstream reconciliation required by `propose-standard-change` step 7, not a request to sweep unrelated old standards drift. T-052's five enumerated claims do not own this specific coverage sentence. + +A path-only check found 241 real relative Markdown path references across the changed documents resolving. The literal illustrative `](...)` in the task's checklist was excluded as prose/code rather than a link. This check does not claim automated validation of every historical anchor; new/changed anchors and referenced sections were inspected in context. + +### Integration + +No required-job name, trigger, permission, action pin, dependency, crate membership, lint policy level or shared-image profile changes. Existing required jobs gain explicit fail-closed gates, and the negative commands run only after their positive commands succeed. The isolated target directory prevents cached lint artifacts from hiding the injected userland regression. The script copies working tracked contents, not historical Git blobs, which is appropriate both locally and in clean hosted checkouts. + +The failed first hosted run is a genuine compatibility observation, not a new runtime issue or a reason to weaken ShellCheck globally. Both measured diagnostic codes are scoped to the one indirectly invoked function. First merged-main / PR / final branch-protection evidence remains outside this development-step review. + +### Checklist + +| Standard item | Disposition | +|---|---| +| Correctness and error paths | Pass; real/synthetic negative outcomes independently exercised | +| Capability semantics | N/A; no kernel/user capability boundary changes | +| Fault containment | No changed kernel fault path; real default smoke retains expected trace | +| Unsafe discipline | N/A; no Rust/assembly/unsafe text changes | +| Error handling | Harness rejects zero and unrelated failure; usage exits 2; exit cleanup inspected and observed | +| Tests | Positive, intended-negative, false-green, unrelated-error, CLI, existing fixtures and real smoke covered | +| Documentation | One Low direct downstream standards finding, R1-CODE-01 | +| Architectural principles P1–P12 | No conflict; no runtime TCB expansion, proprietary blob, dependency or policy reversal | +| Dependencies | None added; dependency workflow N/A | +| Naming/style/portability | Pass; Bash 3.2 execution, complete ShellCheck/actionlint | +| Commit format and ADR references | Pass for all three reviewed commits | +| Lifecycle/branch | `development`; tasks remain `In Review`; no Done promotion or merge authorization inferred | +| Paired source security review | Conditional source/unsafe trigger N/A; independent companion review may be linked by parent | + +### Read coverage and limits + +Read the complete `AGENTS.md`, `CLAUDE.md`, and `current.md`; all 39 extant numbered ADRs in numerical order (0001–0033, 0035–0040; 0034 remains an intentionally absent reservation); every standard under `docs/standards/`; applicable review skills and full code-review master plan; skill index and standard-change procedure. Long reads were bounded and truncated portions recovered. Read the prior Track B.2-1 preflight review, T-031, the full Phase B.2 task index, T-052 to verify downstream ownership, all nine changed files in full, both regression harnesses tests-first, the userland build script, Cargo workspace/userland manifests, toolchain and target configuration, and hello's build script. Baseline/current diff and all three commit messages were inspected. + +No Rust/assembly source was changed or fully re-audited. T-038's known HIGH clobber issue remains explicitly outside this task and this approval; passing clippy/smoke does not disprove it. Miri was not rerun for this tooling-only change. No release/perf profile build, alternate-profile shared-image write, real SMP boot, performance regression study, signal-interruption stress test, GitHub mutation, branch creation/switch, repo edit or commit was performed by this reviewer. Normal and harness-error cleanup was observed; hostile process termination is not claimed tested. + +### Verdict + +**Approve T-031 at `0acf0cd` for this fresh Round 1 code review, with one Low non-blocking documentation finding, R1-CODE-01.** All five axes are covered; no executable-code blocker remains. Independent local checks and the root-supplied successful hosted retry support the implementation. The downstream wording should be reconciled before the final integrated PR. Round 2, parent publication/evidence reconciliation and final maintainer PR review remain required. This verdict does not promote T-031 to Done, authorize a merge or certify kernel soundness. + +## Round 1 CI and integration review + +- **Change:** T-031, approved Track B.2-1 step 3 on `development`, `05f1736..0acf0cdaaf2b8502465d813fa82e0c347a2f70b0` (implementation `82d1c42`, documentation `1cb3526`, hosted compatibility fix `0acf0cd`). +- **Reviewer:** independent fresh delegated reviewer `b21_step3_round1_ci`; requested configuration reported by the orchestrator: `gpt-6.1-sol`, high reasoning. The runtime model cannot be independently introspected in this session. +- **Date:** 2026-10-12, Europe/Istanbul; hosted logs use UTC on 2026-10-11. +- **Risk class:** Ordinary. The diff changes CI wiring, shell scripts and documentation, with no Rust, assembly, production `unsafe`, dependency, authority or syscall contract change. The new lint coverage of existing unsafe code does not itself change that code. A distinct security implementation review is not required for this range. +- **Security-review cross-reference:** n/a for this ordinary change. Existing unsafe/asm debts retain their owning tasks; passing clippy does not establish asm soundness. +- **Authority and limits:** read-only repository review; temporary isolated probes and this `/tmp` report only. No repository edits, commits, branch changes, GitHub mutations or external messages. Root owns artifact/index integration and subsequent fixes. + +### Correctness + +No blocking implementation finding. + +`tools/test-ci-gates.sh:19-33` establishes a disposable tracked-worktree snapshot using `git ls-files -z`, NUL-delimited Bash reads, quoted paths and `cp -p`; it does not check out a historical commit, copy `.git`, copy untracked build output, or reuse the shared Cargo target. The userland mutation is appended only under the temporary tree. The shell mutation creates a new script only there. `CARGO_TARGET_DIR` is set to a sibling temporary target before invoking Cargo, and the EXIT trap removes the common temporary root. + +The rejection contract at `:35-50` requires both a nonzero command exit and the selected diagnostic. An unexpected success is rejected even if output contains the diagnostic, and an unrelated tool failure is rejected rather than treated as proof. The actual probe invocations use the target-aware userland package selection and `-D warnings`, and the same default-severity `shellcheck tools/*.sh` glob as the production gate. The hosted explicit `cargo +"$NIGHTLY_PIN"` selection and the probe's unprefixed Cargo resolve to the same pin through `rust-toolchain.toml`; no different target or lint severity is substituted. + +Independent controlled probes verified six paths, three per mode: success-with-diagnostic rejected, unrelated nonzero failure rejected, matching nonzero failure accepted. Each verified the full current tracked manifest's bytes and file modes (allowing only the intentional userland suffix), the injected source, the command arguments, absence of `.git` and `hello.bin`, independent Cargo target and cleanup after the outcome. The outer temporary path contained spaces and glob characters. Source hashes and modes remained unchanged after all probes. Four usage/help/invalid-arity cases also passed. + +The `smoke.sh` comma quoting preserves the exact `int,unimp` argument. The three changed `${path#"${REPO_ROOT}"/}` expressions treat repository-root glob characters literally. Bash 3.2 tests covered spaces, glob metacharacters and punctuation; all removed exactly the intended prefix. The cleanup function suppression does not alter trap execution. + +### Style + +No new actionable style finding. Independent `shellcheck tools/*.sh` with Homebrew ShellCheck 0.11.0, full `actionlint`, Bash 3.2 syntax checks and `git diff --check` pass. Changes are narrow and repository text is English. Existing action SHAs, workflow permission scope and required-check display names remain unchanged. The extra nightly-variable quotes fix measured actionlint/ShellCheck issues without changing the selected toolchain. + +The only new ShellCheck directive is immediately attached to `cleanup_in_flight`, with the explicit trap reason and measured compatibility codes `SC2317,SC2329`; it is not a file-wide disable. Independently removing only this directive from a temporary copy produces SC2329 under 0.11.0. The function is demonstrably reached through the adjacent EXIT, INT and TERM traps. Hosted 0.9.0's SC2317 behavior is supported by the first-run evidence supplied by root and the recorded task history, not falsely claimed as a locally reproduced 0.9.0 run. + +All three reviewed commits use Conventional Commits and `Refs: ADR-0040`. No `Audit:` or `Security-Review:` trailer is newly required by this ordinary range. + +### Test coverage + +Independent results on the reviewed implementation: + +| Check | Result and meaning | +|---|---| +| ShellCheck 0.11.0 at default severity over `tools/*.sh` | Exit 0; all scripts, including both harnesses, lint clean. | +| Full actionlint | Exit 0, including embedded shell analysis. | +| `/bin/bash -n` for changed scripts | Exit 0 under macOS Bash 3.2.57. | +| Exact bare-metal userland clippy command | Exit 0 with a separate temporary `CARGO_TARGET_DIR`; no shared image build. | +| Real `--shell` negative probe | Harness exit 0 after actual ShellCheck exit 1 and SC2086. | +| Real `--userland` negative probe | Harness exit 0 after actual clippy exit 101 and `clippy::clone_on_copy`. | +| Six controlled harness outcome cases | All pass; zero and unrelated failures fail closed, expected diagnostic plus nonzero succeeds. | +| Snapshot/content/mode/target/cleanup checks | All pass in both modes and all three outcomes. | +| Four CLI contract cases | No arguments, help, invalid option, extra argument return expected statuses. | +| Existing QEMU argument suite | 59 cases pass with stubbed QEMU; no SMP runtime claim. | +| Additional smoke `--int` argv inspection | One literal `int,unimp` value and intact spaced ELF path under Bash 3.2. | +| Three literal-prefix quoting cases | Exact intended prefix removal under Bash 3.2. | +| Suppression-removal countercheck | Only trap callback SC2329 reproduced under local 0.11.0. | +| Changed Markdown relative file targets | 241 resolve, excluding inline-code link-syntax examples. Anchors are not included in this independent filesystem check. | + +The generic failure-path probes use controlled stub tools to test the harness contract, and are distinct from the real tool negative runs above. The reported success is the harness accepting an intended rejection, not a red production workflow. + +Root provided local positive verification of fmt, host/kernel clippy, 366 passing host tests with two ignored HAL doctests, the userland image build and real single-core debug smoke. Another reviewer owns the independent real default smoke/build pass; this reviewer deliberately did not overwrite `userland/hello/hello.bin`, rebuild the shared kernel image or rerun shared Miri. The changed script token's behavior is additionally checked here by actual argv inspection. No new production Rust behavior requires new Rust unit tests. + +Hosted evidence is separated below. No additional missing test category was found for this range. + +### Documentation + +The updated CI guide correctly names the new production gates, their corresponding expected-failure probes and the distinction between a rejected injected regression and a workflow failure. The infrastructure standard removes its inaccurate two-alias workspace-coverage claim, gives the separate bare-metal userland command, documents default-severity ShellCheck and scoped suppression discipline, and links Accepted ADR-0040. + +ADR-0040 was already Accepted before the standard implementation commit; its phase scope, task execution/evidence policy and reference to `propose-standard-change` motivate this change. No Accepted ADR body is rewritten and no materially different policy is selected. The optional alias was reasonably omitted and that routine choice is recorded in task history. + +T-031 and its task-index row are `In Review`. `current.md` keeps final maintainer PR review outstanding and preserves T-033/T-037 as `In Review` after their implementation gates and review rounds. The task history distinguishes the opening baseline, local implementation, failed first hosted run and retry pending at the reviewed commit. The hosted-negative/green criteria remain unchecked until evidence is incorporated. Conditional Miri/audit/security criteria are explicitly explained as N/A in history rather than evidence of work that did not occur. The later hosted retry result needs root's normal evidence update; this review does not promote a task to `Done`. + +**Corroborated Low finding — shared ID R1-CODE-01, not a second independent finding:** after root relayed the peer result, direct inspection confirmed `docs/standards/testing.md:105` still says the host/kernel aliases together cover the workspace; `docs/standards/release.md:61` enumerates only those clippy aliases and omits the new shell/userland lint coverage. The former is factually stale, and the latter is an incomplete summary of the newly enforced gates. Update these downstream summaries to agree with infrastructure, retain appropriate ADR references, and search for remaining copies of the old two-alias claim. Root has accepted this documentation fix before round 2. No additional reviewer-originated finding was found. Unrelated pre-existing standard/document drift remains with its existing task owners. + +### Integration + +The new production ShellCheck step prints its installed version and runs before the shell negative probe in `lint-and-host-test`. A genuine positive-gate failure prevents later steps. The kernel job builds userland before kernel build/clippy, then runs bare-metal userland clippy and its isolated negative probe. The pinned nightly, required clippy component and `aarch64-unknown-none` target are already installed. The negative userland snapshot recompiles its injected source against an independent target; stale shared artifacts cannot certify it. + +No new job, check display name, secret, package dependency, installation action or widened token permission is introduced. ShellCheck is deliberately the preinstalled runner tool anticipated by the task; version drift is observable in logs, and both actual local 0.11.0 and hosted 0.9.0 are evidenced. Required branch-protection checks retain their names, so existing merge enforcement continues to cover these added steps without a protection migration. + +**Hosted evidence supplied by root:** [first run 38177838556 at `1cb3526`](https://github.com/HodeTech/Tyrne/actions/runs/38177838556) failed in the fast lane because ShellCheck 0.9.0 calls the indirect callback SC2317 rather than local 0.11.0's SC2329. Userland lint and its probe succeeded there. `0acf0cd` adds only that measured code to the existing function-scoped directive and records the result. This failed run is not treated as a pass. + +**Hosted retry:** root reports [run 38178035728 at exact head `0acf0cdaaf2b8502465d813fa82e0c347a2f70b0`](https://github.com/HodeTech/Tyrne/actions/runs/38178035728) completed successfully in all five jobs. This reviewer independently read the supplied downloaded `hosted-fastlane.log` and `hosted-kernel.log`: the former shows ShellCheck version 0.9.0, its positive command followed by SC2086 rejection at exit 1; the latter shows positive target-aware userland clippy followed by `clippy::clone_on_copy` rejection at exit 101. Full run status and exact-head association were retrieved by root, not independently queried by this reviewer. This is hosted `development` evidence; it establishes neither a final PR merge nor a first merged `main` run. + +### Explicit checklist disposition + +| Required review item | Disposition | +|---|---| +| Change intent/description | Read task context, acceptance criteria, review history and all commit descriptions before implementation diff. | +| Tests before implementation | Read new expected-failure harness and existing QEMU fixtures first, then full nine-file diff and affected command/trap context. | +| Correctness/error handling | Clean; command status and diagnostics both required; tested unexpected success and wrong-failure rejection. | +| Capability semantics/trust boundary | N/A to production authority: no capability or kernel/user boundary mechanism changes. Temporary host filesystem scope reviewed. | +| Fault containment | Production fault path unchanged; no new userspace-to-kernel path. Existing smoke fault parsing not broadened. | +| Unsafe discipline | No Rust/asm/unsafe diff; no audit amendment or separate security implementation pass required here. | +| Error APIs/unwrap/hot paths | N/A to Rust API changes; shell error propagation reviewed and exercised. | +| Tests | Real positive/negative lint commands plus isolated harness/error/cleanup and Bash portability checks pass. | +| Documentation | One corroborated Low downstream-summary issue, root's planned fix; no other actionable gap. | +| Architectural principles P1–P12 | No runtime architecture expansion, ambient kernel authority, dependency, blob or binary artifact addition; pinned Rust workflow preserved. | +| Dependencies | No Cargo/action dependency addition or pin bump; preinstalled ShellCheck use is the planned tool. | +| Naming/style | Clean; default ShellCheck and actionlint pass, only function-scoped reasoned false-positive directive added. | +| Commit format/ADR trail | All reviewed commits conventional, ADR-0040 trailers valid; standard follows Accepted motivating ADR. | +| Security review gate | Ordinary range, so no distinct security review required for this scope. | +| Run/build/smoke | Independent isolated lint/probe checks here; shared real build/smoke delegated to root/peer, evidence attribution explicit. | +| Artifact/index/commit side effects | Root integrates this temporary report into the canonical artifact; this read-only reviewer does not edit index or commit. | + +### Mandatory read coverage + +Read in full before the substantive review: repository `AGENTS.md`, canonical `CLAUDE.md`, and `docs/roadmap/current.md`, including historical banners; all existing numbered ADR files in numerical order, **0001–0033 and 0035–0040** (0034 has no file and is an explicitly reserved slot); ADR index and template; all standard files: `README.md`, `architectural-principles.md`, `bsp-boot-checklist.md`, `code-review.md`, `code-style.md`, `commit-style.md`, `documentation-style.md`, `error-handling.md`, `infrastructure.md`, `localization.md`, `logging-and-observability.md`, `release.md`, `security-review.md`, `testing.md`, `unsafe-policy.md`. + +Also read in full `.agents/skills/README.md`, `perform-code-review/SKILL.md`, `conduct-review/SKILL.md`, `propose-standard-change/SKILL.md`, the code-review master plan and the preceding Track B.2-1 preflight review. The review skills were applied; `propose-standard-change` was read to audit the standard-change procedure, not to edit standards. Read the full T-031 task, both relevant test harnesses, complete nine-file range diff, full CI workflow, CI guide, build-userland helper, Cargo configuration and toolchain pin. Read focused task-index approval/sequence/index portions and the Phase B.2 Track B.2-1 scope/criteria; no claim to reread the whole unrelated 46-task corpus or whole Phase B.2 backlog. Relevant perf trap and report-generation context and full smoke helper were inspected. Bounded reads recovered any tool-truncated mandatory or diff sections; no unresolved truncation is counted as full coverage. + +### Verdict + +**Approve — implementation and integration are ready, with one corroborated Low documentation correction to carry into the next round.** + +No blocking finding and no additional reviewer-originated actionable finding. R1-CODE-01 remains the shared downstream-documentation item, not a duplicate counted twice. Hosted retry evidence closes the local-versus-hosted compatibility uncertainty for the reviewed code. Root should record that evidence and apply the accepted Low correction before the second fresh round. This is round-1 source/CI approval, not approval to skip round 2, merge a final PR, promote T-031 to `Done`, or claim post-merge/default-branch evidence. + +## First-round reconciliation + +| Finding | Root verification | Resolution | +|---|---|---| +| R1-CODE-01 (Low; corroborated by integration) | The testing summary still claimed two aliases covered the workspace; release omitted the newly enforced gates. | Both summaries now name userland lint, ShellCheck and isolated rejection probes; both reference Accepted ADR-0040. Downstream search found no remaining two-alias workspace-coverage claim. An intentionally future changelog reference is plain code rather than an unresolved link. | + +All relative paths in touched Markdown resolve. This correction changes documentation only; implementation checks are the reviewed local and hosted checks above. Second fresh round pending. + +## Round 2 code review + +- **Date:** 2026-10-12, Europe/Istanbul. +- **Change:** T-031, Track B.2-1 step 3; `development`; `05f1736..e79e10a5dbe2ea9cd69d714e7f4338372066e788`. Implementation `82d1c42`, initial documentation `1cb3526`, hosted compatibility correction `0acf0cd`, first-round reconciliation `e79e10a`. +- **Reviewer:** fresh independent delegated agent `b21_step3_round2_code`, Codex, acting on behalf of @cemililik. The orchestrator explicitly requested `gpt-6.1-sol` with high reasoning and `fork_turns: none`, under the user-authorized model choice. This is requested configuration provenance; no independently exposed runtime model identifier is available, so no claim about a verified runtime model name is made. This is a new agent pass, not a continuation of either first-round reviewer. +- **Risk class:** Ordinary CI, shell tooling and documentation. No production Rust, assembly, unsafe invariant, syscall, capability, scheduler, MMU or boot implementation changes. Linting an existing unsafe source file does not change that source's safety argument. +- **Security-review cross-reference:** N/A for this scoped delta. Existing HIGH T-038 remains excluded and unresolved by this verdict. +- **Procedure:** `perform-code-review`, `conduct-review`, full code-review master plan; five roles executed sequentially. `propose-standard-change` read to audit standard governance. Parent instructions limit publication to this `/tmp` artifact; no repository edits, index updates, commits, branch changes, GitHub mutations or external messages were performed. + +### Correctness + +**No executable-code blocker found.** The stated task contract was read before implementation; the new rejection harness and existing QEMU fixtures were read first, followed by helper behavior, workflow callers, modified script contexts and documentation. There are no new Rust types or implementation dependency chains to order. + +- `tools/test-ci-gates.sh` validates mode/arity before creating temporary state. It copies current tracked file contents using NUL-delimited `git ls-files`, quotes filesystem operands and preserves script permissions. The random temporary root contains both the copied tree and a separate Cargo target directory. It excludes `.git`, untracked build caches and the shared untracked `hello.bin`. +- The appended clone-on-Copy function and unquoted shell variable exist only in that disposable snapshot. Neither negative mode invokes `build-userland.sh` or writes the shared image. EXIT cleanup covers normal completion and explicit harness errors. +- `run_negative` requires nonzero exit **and** the chosen diagnostic. A zero exit printing the expected diagnostic is rejected. An unrelated failure is rejected. Real intended failures are accepted by the harness. This avoids conflating a successful rejection probe with a red production gate. +- The shell production gate prints its installed version and runs the full `tools/*.sh` glob at default severity. Its positive gate precedes its negative probe. The bare-metal userland command selects both packages, the exact aarch64 target and `-D warnings`; it runs after the default debug userland image build, adjacent to kernel clippy, followed by its isolated probe. No `continue-on-error` is added to these required checks. +- CI's `cargo +"$NIGHTLY_PIN"` prefix remains a single correct toolchain argument. The harness's bare Cargo selects that same pin through the copied `rust-toolchain.toml` and configuration. +- `smoke.sh` passes the same two arguments, `-d` and literal `int,unimp`. The change removes the comma-parsing lint without changing QEMU behavior. The three modified perf report prefix expansions quote the inner repository-root value, avoiding pattern interpretation of literal glob metacharacters. +- The suppression is function-scoped to the demonstrated indirect trap callback, naming measured 0.9/0.11 diagnostic codes and its EXIT/INT/TERM reason. All three trap registrations still call the function. No broad severity reduction or file-wide suppression is introduced. + +### Style + +**Clean.** All tooling scripts pass default-severity ShellCheck 0.11.0 and system Bash 3.2.57 syntax checks. Full actionlint 1.7.12 passes with its shell analysis enabled. `git diff --check` passes. Repository text is English and modified shell follows existing conventions. + +All four range commits use Conventional Commits and `Refs: ADR-0040`; the reconciliation commit links the first review artifact.

The task index retains `In Review`; no Done promotion is asserted. + +**R2-CODE-01 — Low, non-blocking: reconcile the remaining live current-status row.** At reviewed HEAD, `docs/roadmap/current.md:85` says `T-031 (local implementation gates passed; hosted evidence and two fresh rounds pending)`. Its current opening banner at line 5 and T-031's last two history rows record successful hosted retry and approved first fresh round. This is a present-tense live row, unlike the dated historical banners, so it sends contradictory instructions about work still outstanding. Update this narrow T-031 clause to the actual hosted/review state when publishing round 2; synchronize the adjacent line-84 active-task summary and opening pointer as appropriate, preserving the historical B6 suffix. Root independently confirmed the source contradiction and accepted the correction. This finding does not question hosted execution or create a runtime risk. + +No other actionable documentation issue found within the changed contract. Unrelated old CI/coverage/stable prose remains outside this task's direct downstream reconciliation scope. + +### Integration + +**No implementation blocker.** Required job names, triggers, token permissions, action pins, workspace membership and toolchain stay unchanged. Existing required jobs gain the lint gates rather than introducing unregistered status-check names. The job installs the required clippy component and aarch64 target. New probes are executable and included in the positive shell glob. The negative userland target cannot accidentally reuse the positive build cache to hide the injected regression. + +**Hosted evidence is separate from these independent local checks.** Root reports [corrected implementation retry 38178035728 at `0acf0cd`](https://github.com/HodeTech/Tyrne/actions/runs/38178035728) successful in all five jobs, and [documentation reconciliation run 38178552332 at `e79e10a`](https://github.com/HodeTech/Tyrne/actions/runs/38178552332) also green. No executable source changed after `0acf0cd`. This reviewer did not independently query hosted run metadata. I directly read supplied downloaded logs: `hosted-fastlane.log` records ShellCheck 0.9.0 at line 174, SC2086 rejection with exit 1 at line 184, and 59 cases at line 618; `hosted-kernel.log` shows positive userland clippy completion followed by clone-on-Copy rejection with exit 101 at line 214. Those logs support the actual gate behavior; exact run/head association and complete job status remain parent-supplied metadata. + +The first [run at `1cb3526`](https://github.com/HodeTech/Tyrne/actions/runs/38177838556) remains honestly recorded as failed: hosted ShellCheck 0.9.0 reported the indirect trap function as SC2317. The narrow `0acf0cd` correction supplements local 0.11.0's SC2329 suppression. This is compatibility evidence, not a claim that the failed workflow passed. No merged-main, final-PR, branch-protection mutation or default-branch registration evidence is inferred from development runs. + +### Explicit reviewer checklist + +| Standard item | Disposition | +|---|---| +| Stated intent and tests-first procedure | Pass; tests read before workflow/script implementation; helper/caller flow traced | +| Correctness and failure paths | Pass; real expected failures and independently controlled false-green/wrong-failure cases | +| Capability semantics | N/A; no runtime capability or authority contract changes | +| Fault containment | Runtime fault mechanism unchanged; real default debug smoke fault-clean | +| Unsafe discipline | N/A; no Rust/asm/unsafe diff or changed safety argument | +| Error handling | Nonzero status and diagnostic required; usage statuses and EXIT cleanup exercised | +| Tests | Real lint/build/smoke, host tests, six controlled outcomes, CLI, 59 fixtures, Bash 3.2 and cleanup pass | +| Documentation | R1 Low fixed; one new Low R2-CODE-01 current-status contradiction | +| Architectural principles P1–P12 | No conflict; no runtime TCB expansion, ambient authority, dependency, proprietary blob or decision reversal | +| Dependency policy | N/A; no added Cargo/action dependency or pin bump | +| Naming/style | Pass; complete ShellCheck, actionlint, Bash syntax and whitespace checks | +| Commit messages and ADR trail | Pass; four conventional commits with ADR-0040 references | +| Conditional paired security review | N/A for this ordinary delta; known T-038 remains explicitly excluded | +| Branch/lifecycle | `development`, clean; T-031 remains `In Review`; final maintainer authority preserved | +| Artifact/index publication | Parent-owned by instruction; this complete independent report saved only under `/tmp` | + +### Read coverage and limits + +Read repository AGENTS and canonical CLAUDE in full; all of `current.md`, including historical banners; all 39 extant numbered ADRs in numerical order (0001–0033, 0035–0040; 0034 has no file); all 15 files in `docs/standards/` including the index; skill index; full `perform-code-review`, `conduct-review` and `propose-standard-change` skills; full code-review master plan and prior T-031 first-round artifact. Long mandatory reads were split and truncated substantive portions recovered through bounded reads. + +Read both regression harnesses in full before implementation, full workflow and CI guide, complete task, changed standards and range commit messages, changed script diff/context (including all trap registrations and modified prefix expressions), build-userland helper, workspace/userland manifests, target/Cargo configuration, toolchain and hello build script, and the Track B.2-1 sequence/criteria and modified task/review index rows. All range changes were inspected; no claim is made to reread the entire unrelated 46-task backlog, the entire 600-line perf harness beyond changed/adjacent context, or every unchanged Rust file. + +No production Rust/assembly was changed or fully re-audited. Passing clippy and smoke cannot disprove the explicitly excluded T-038 unsafe asm debt. Miri, stable and coverage were not independently rerun for this tooling-only range; their full hosted success is parent-supplied. No release/perf build or alternate-profile `hello.bin` write, real SMP boot, hardware test, performance study, kill/signal-interruption stress test, repository edit, branch switch, commit or external mutation was performed. Normal and harness-error cleanup was exercised; hostile termination cleanup is not claimed. Automated validation of every historical Markdown anchor is not claimed. + +### Verdict + +**Approve T-031 at `e79e10a` for this fresh Round 2 code review, with one Low non-blocking documentation finding, R2-CODE-01.** All five axes were completed and no executable-code blocker remains. R1-CODE-01 is fixed. Independent local lint, real negative probes, harness sensitivity/cleanup, 366 host tests, 59 argument cases and default debug smoke all pass. Root should reconcile the live status clause while publishing this round. This approval neither promotes the task to Done nor authorizes a merge or certifies kernel soundness. + +## Round 2 CI and integration review + +- **Change:** T-031, approved Track B.2-1 step 3, `development`, `05f1736..e79e10a5dbe2ea9cd69d714e7f4338372066e788`. Four commits: implementation `82d1c42`, standards/history `1cb3526`, hosted compatibility correction `0acf0cd`, first-round reconciliation `e79e10a`. Thirteen changed files; 387 additions / 50 deletions, including the first-round review artifact. +- **Reviewer:** fresh independent delegated reviewer `b21_step3_round2_ci`, Codex, on behalf of @cemililik. The parent reports requested configuration `gpt-6.1-sol` / high; this is orchestration provenance. The exact runtime model identifier is not independently exposed to this reviewer. +- **Date:** 2026-10-12, Europe/Istanbul. Hosted log timestamps are UTC on 2026-10-11. +- **Risk class:** Ordinary CI, developer tooling and documentation. No Rust, assembly, production unsafe reasoning, capability contract, kernel boot implementation, dependency or syscall changes. +- **Security-review cross-reference:** N/A to the conditional source/unsafe-change gate. Existing T-038 remains outside this range; lint success does not certify assembly correctness. +- **Procedure and authority:** `perform-code-review`, `conduct-review`, complete code-review master plan; all five roles considered sequentially. Tests were read before implementation; scripts and command configuration before workflow callers and downstream documentation. Read-only repository review; this temporary report is handed to the parent for canonical artifact/index integration. No repo edit, commit, branch change, GitHub mutation or external message. + +### Correctness + +No executable-code blocker found. + +The positive bare-metal clippy step names both packages, explicitly selects `aarch64-unknown-none`, and denies warnings. The kernel job installs the required clippy component and target, builds the debug userland image before kernel build/clippy, then runs the userland lint step and its negative probe. No recursive Cargo operation or image writer is added to the probe. + +The positive ShellCheck step prints the installed version and checks `tools/*.sh` at default severity before the shell negative probe. Neither positive gate uses `continue-on-error`, an unconditional success suffix or a permissive conditional. A genuine positive failure prevents subsequent steps in that job. The informational coverage exception remains confined to its existing job. + +`test-ci-gates.sh` validates its mode before allocating, makes an unpredictable temporary root, copies current tracked contents with NUL-delimited paths and preserved script modes, and mutates only that copy. It exports a sibling private Cargo target directory. Neither mode invokes `build-userland.sh`; the shared `.bin` is not copied from the untracked worktree. The EXIT trap removes the common root on normal completion and shell errors. + +Expected failure requires both nonzero status and the intended diagnostic. Independent controlled tools proved that zero status containing the expected diagnostic still fails the harness, and an unrelated exit 42 also fails it. Matching nonzero status plus diagnostic succeeds. Both modes were exercised, with assertions on private cwd/target and absence of `.git`, shared target and `hello.bin`. Separate injected `cp` and `mkdir` failures propagated exit 42 in both modes and left no probe directory. Tracked source hashes and modes remained unchanged. + +Pin quoting keeps each selected toolchain a single argument; `cargo +"$NIGHTLY_PIN"` selects the same pin as the disposable tree's `rust-toolchain.toml`. The comma token remains one literal `int,unimp` argument. The three quoted inner prefix expressions now treat the repository root literally. No Rust or assembly behavior changes. + +### Style + +No actionable style issue. Full actionlint and default-severity ShellCheck 0.11.0 pass. The changed scripts parse under system Bash. The sole new lint suppression is immediately attached to the indirect cleanup callback, names only the measured SC2317/SC2329 compatibility codes, and gives the EXIT/INT/TERM trap reason. The adjacent trap registrations corroborate that explanation; there is no file-wide disable. + +All four reviewed commits use conventional messages and valid `Refs: ADR-0040` trailers. English repository prose and existing shell conventions are preserved. No action pin, permission scope, required-check display name, crate dependency or toolchain version changes. + +### Test coverage + +Independent checks in this fresh round: + +| Check | Result | +|---|---| +| `shellcheck --version`; `shellcheck tools/*.sh` | 0.11.0; positive command exit 0 at default severity | +| Full `actionlint` | Exit 0, including embedded shell analysis | +| Real `/bin/bash tools/test-ci-gates.sh --shell` | Harness exit 0; actual ShellCheck exit 1 with SC2086 | +| Real `/bin/bash tools/test-ci-gates.sh --userland` | Harness exit 0; actual clippy exit 101 with `clippy::clone_on_copy` | +| Exact positive bare-metal userland clippy | Exit 0 using a fresh temporary `CARGO_TARGET_DIR`; target removed afterward | +| Both modes, controlled `cp` failure | Exit 42 propagated; probe root removed | +| Both modes, controlled `mkdir` failure | Exit 42 propagated; probe root removed | +| Both modes, command success containing expected diagnostic | Harness exit 1; false green rejected | +| Both modes, unrelated nonzero command | Harness exit 1; wrong failure rejected | +| Both modes, matching nonzero command/diagnostic | Harness exit 0; expected rejection accepted | +| Controlled command isolation assertions | Private tree and Cargo target; no `.git`, shared target or `hello.bin`; cleanup after every outcome | +| Before/after tracked byte and mode digest | Identical | +| Changed shell files, `/bin/bash -n` | Exit 0 | +| `git diff --check 05f1736..e79e10a` | Exit 0 | +| Changed Markdown relative file references | 266 resolve; not a claim about every historical anchor | +| Final branch/worktree check | `development`; clean | + +Controlled command substitutes exercise the harness's own failure contract, separately from the two real lint-negative runs. A passing negative harness means a disposable regression was rejected; it is not a red production gate. The initial controlled-probe invocation yielded without its completion handle being retained, so its result was not counted; the bounded captured invocation above supplies the stated assertions. + +The prior complete artifact records independently passing 59 QEMU argument cases and actual default debug smoke, plus fmt, host/kernel clippy and 366 host tests with two ignored HAL doctests. The parent also supplied those implementation results. This reviewer did not repeat already-passing shared build/runtime checks without a new concern, write shared images, run another profile, or rerun Miri. The narrow quoting change does not add a runtime code path requiring new Rust tests. + +### Documentation + +R1-CODE-01 is resolved in the reviewed tip: testing and release summaries now include bare-metal userland clippy, ShellCheck and isolated rejection probes. Both retain a reference to Accepted ADR-0040 and defer to the exact target-aware required-gate commands. The intentionally future changelog path is plain code. A downstream search finds the old two-alias whole-workspace coverage wording only in the explicitly historical first-round finding record, not an active standard claim. + +The CI guide describes both added production gates, their disposable probes, default severity, recorded tool versions and the distinction between intended lint rejection and workflow failure. Accepted ADR-0040 precedes the standard edits; this implements its existing policy rather than rewriting an Accepted decision or selecting a new one. No architectural-principle update is warranted. + +**R2-CODE-01 — Low, non-blocking; corroborated shared finding, not a duplicate.** `docs/roadmap/current.md:85` says T-031's hosted evidence and two fresh rounds remain pending, while its live lead at line 5 correctly records hosted success and first-round approval. The line 84 live task prefix also mentions only local implementation gates. These live pointers should agree after the Round 2 reconciliation, while preserving their historical B6 suffixes. The parent reports that the independent code reviewer found the same line-85 discrepancy and verified the line-84 prefix. This CI reviewer directly confirmed both against line 5, T-031 history and supplied hosted logs. This is status-document reconciliation, not a CI implementation blocker. After this finding was reported, the parent states that all three live pointers were corrected in an uncommitted current.md status edit, preserving B6 history. This reviewer did not repeat the inspection after that parent-owned fix; the finding above describes the committed reviewed tip. + +Task, task index and current focus retain `In Review`. No local or agent result is used to promote Done or to claim a final PR merge/default-branch run. + +### Integration + +Existing required jobs gain the checks without changing their names, triggers, least-privilege token permissions or action SHAs. Existing branch-protection names therefore continue to encompass the added steps. The static workflow is fail-closed at positive-gate failure. The independent probe target prevents shared cached Rust artifacts from certifying the injected source. + +Hosted evidence remains distinct from local verification. The parent supplies metadata that the first run at `1cb3526`, [38177838556](https://github.com/HodeTech/Tyrne/actions/runs/38177838556), failed because hosted ShellCheck 0.9.0 reports the indirect callback as SC2317. The failed run is retained explicitly in task/review history. `0acf0cd` adds only that observed code to the existing function-scoped suppression. The workflow is not weakened globally. + +The parent reports all five jobs successful at corrected implementation `0acf0cd`, [38178035728](https://github.com/HodeTech/Tyrne/actions/runs/38178035728), and documentation reconciliation `e79e10a`, [38178552332](https://github.com/HodeTech/Tyrne/actions/runs/38178552332). Exact-head association and whole-run success are parent-fetched metadata, not independently queried here. This reviewer directly inspected parent-downloaded fast-lane/kernel logs: ShellCheck 0.9.0, positive shell lint followed by SC2086 rejection at exit 1, positive target-aware userland clippy followed by `clippy::clone_on_copy` rejection at exit 101. No executable change follows `0acf0cd` in this range. These are hosted `development` results, not final PR, first merged-main or default-branch registration evidence. + +### Explicit checklist disposition + +| Standard item | Disposition | +|---|---| +| Intent before implementation | Task story, contract and history read; range and exclusions explicit | +| Tests first, topological diff | Both harnesses before scripts/configuration/workflow callers/documentation | +| Correctness | Pass; explicit package/target selection and positive-before-negative order | +| Capability semantics | N/A; no production authority or kernel/user contract change | +| Fault containment | Production fault paths unchanged; prior real debug smoke evidence retained | +| Unsafe discipline | N/A; no Rust/assembly/unsafe diff, audit amendment or security trailer required | +| Error handling | Pass; command and setup errors propagate; false green/wrong failure rejected; cleanup observed | +| Tests | Real positive/negative lints and independent setup/outcome/isolation probes pass | +| Documentation | R1 fixed; one shared Low live-status inconsistency, R2-CODE-01 | +| Architectural principles P1–P12 | No conflict, runtime TCB expansion, binary blob or speculative API | +| Dependencies | None added; add-dependency workflow N/A | +| Naming/style/portability | Pass; ShellCheck/actionlint and system Bash syntax | +| Commit messages/ADR references | All four conventional; ADR-0040 exists and was Accepted before standards | +| Security review gate | Ordinary scoped delta; separate implementation security review N/A | +| Run/build/runtime scope | Isolated lint here; prior root/peer shared build/debug smoke explicitly attributed | +| Lifecycle and artifact publication | Development/In Review preserved; parent publishes artifact/index and fixes status pointers | + +### Read coverage and limits + +Read AGENTS.md, full CLAUDE.md and full current focus, including historical banners; all 39 existing numbered ADRs in numerical order (0001–0033 and 0035–0040; no 0034 file); every file under `docs/standards/`; skill index, `perform-code-review`, `conduct-review`, complete code-review master plan and standard-change procedure.

Existing workspace lint inheritance, warning enforcement and kernel denies are preserved. HAL receives no exception. The ten new exception groups were inspected together with their entire attached function bodies, including multiline attributes and feature selection: + +| Functions | Lints allowed | Classification and evidence | +|---|---|---| +| `main::kernel_main_high` | expect, panic | One-shot trusted boot: static PMM/linker alignment, initially empty arenas/tables, loader/object setup and scheduler population before start | +| `perf_bench::run` | expect, panic | One-shot measurement setup: trusted static image, fixed capacities, task/cap construction and publish-before-start order | +| `main::idle_entry` | expect | Trusted scheduler invariant: yielding after start requires a current task; no init classification is falsely applied to its loop | +| `main::task_a`, `main::task_b` | expect, panic | Trusted one-round kernel demo with static capability tables and fixed rendezvous protocol; unchanged runtime behavior | +| `perf_bench::driver_yield` | expect | Trusted post-start current-task invariant | +| `perf_bench::driver_send`, `perf_bench::partner_recv` | expect | Statically provisioned narrow SEND/RECV capabilities and fixed benchmark ping-pong protocol | +| `exceptions::irq_entry` | panic | Existing unhandled-IRQ fatal abort after EOI; spurious/timer branches retain ordinary return | +| `exceptions::panic_entry` | panic | Existing deliberate fatal unhandled-exception policy; no added unwrap/expect allowance | + +Every new allowance has `reason = ...` and is attached to a function. None is crate/module-wide. `syscall.rs` and MMU have none. The exceptions preserve the ADR/error-handling policy rather than introducing a new exception policy. The guide and task explicitly avoid claiming that three Clippy lints forbid assertions or establish a panic-free kernel. Existing non-SVC EL0 fatal behavior is unchanged and outside this scoped approval. + +`QemuVirtMmu::unmap` still validates VA alignment, calls the same walker with the same root, VA, flags, null provider and literal `true`, then returns the descriptor-derived frame and `MapperFlush`. Only the unused third argument changes from constructing/unwrapping an aligned zero frame to copying `as_.root`. `PhysFrame` is a copyable aligned-address wrapper; passing it does not create another ownership token or dereference the frame. In `walk_and_install_leaf`, the `unmap` branch reads the L3 descriptor, checks validity, masks the output PA, clears the descriptor and returns that PA's typed frame. Every use of parameter `pa` occurs solely in the `else` map branch. Intermediate walking propagates `unmap` and neither allocates nor consumes the provider when true. The replacement therefore changes no descriptor, allocation, pointer computation, returned frame, error, or caller flush obligation. + +**Reviewed the changed unsafe call and adjacent SAFETY reasoning in `bsp-qemu-virt/src/mmu.rs:306–334`; agree with the unchanged-root/unused-PA argument for literal `unmap = true`.** This code approval is scoped to that changed argument/reasoning, not a certification of every historical walker or SMP claim. The appended UNSAFE-2026-0025 amendment explicitly preserves that limitation and accurately states that the normal smoke does not exercise BSP unmap. The distinct security reviewer has separately approved that changed argument/reasoning, as recorded in the paired report. + +The probe uses `black_box(None::).unwrap()` in non-test crate-root code outside allowed functions. `black_box` prevents the test from relying on an obviously constant None diagnostic; the required diagnostic is `clippy::unwrap_used`. `run_negative` requires nonzero command status and that specific diagnostic; command success or unrelated failure alone cannot pass. Exact aliases retain their target/package selection. The BSP builds its debug image before linting only inside the tracked-current-worktree copy. Each invocation replaces `CARGO_TARGET_DIR` with a private sibling directory, avoiding shared caches and image writes. The existing NUL-delimited copy loop and quoted paths preserve tracked names/modes. EXIT cleanup handles the tested normal/error exits. + +### Style + +**Clean.** Independent default-severity ShellCheck on the changed script and Bash syntax checks pass, as does range whitespace validation. The implementation uses existing Rust attribute forms and explicit scoped reasons; no broad suppression, dependency, toolchain, target flag or unrelated refactor appears. English prose and conventional commit subjects are maintained. All three range commits include `Refs: ADR-0040`; implementation and audit reconciliation include `Audit: UNSAFE-2026-0025`. The security trailer correctly awaits actual separate approval and parent-owned recording rather than being fabricated in advance. + +### Test coverage + +**Adequate for this enforcement change; no missing blocking test.** The new persistent probes exercise real compiler behavior, and the independent controls establish that they detect removal of the new enforcement. No new public API or Error variant requires another contract test. The MMU substitution is behavior-preserving; existing `cap_unmap_returns_unmapped_frame` asserts returned PA and both flushes, and loader rollback tests assert committed leaf-frame reclamation. Those run over a fake MMU, so they are complementary evidence rather than execution of this hardware walker. + +Independent verification in this review: + +| Check | Observed result | +|---|---| +| Actual `/bin/bash tools/test-ci-gates.sh --hal` in private tracked snapshot | Harness exit 0; real Clippy exit 101, `clippy::unwrap_used` | +| Actual `--bsp` in private tracked snapshot | Harness exit 0; private 117-byte debug image built, real Clippy exit 101 with intended lint | +| Remove only HAL unwrap deny in private snapshot, rerun exact harness | Harness exit 1; Cargo succeeds and script rejects the unexpected-green regression | +| Remove only BSP unwrap deny in private snapshot, rerun exact harness | Harness exit 1 with same unexpected-green diagnostic | +| Private probe-directory cleanup | Checked after all four cases; outer snapshot/targets also removed by `TemporaryDirectory` | +| Original HAL/BSP sources and existing hello image | SHA-256 unchanged before/after; outer copied tree never gained hello.bin | +| Changed script ShellCheck / `/bin/bash -n` / range whitespace | All exit 0 | +| Unsafe-log history preservation | Removing exactly the one new T-032 amendment yields byte-identical baseline log | +| Changed Markdown relative file destinations | 418 references resolve; heading anchors not checked | +| Reviewed tip and working tree | Exact `4f2c38c6a8fdf221e00a0f0cb461303ed0b74b55`, clean | + +Captured independent real-case results: `/tmp/tyrne-b21-r1-code-verification.json`.

No failed check is counted as evidence and no repository fix was indicated. + +Parent-supplied implementation evidence separately covers fmt, ShellCheck 0.11.0/actionlint, clean host/default/release/perf clippy and corresponding builds, 366 host and 366 Miri passes with existing warnings/two ignored HAL doctests, debug QEMU greeting/exit/completion/two expected SVCs/no faults, unchanged 117-byte SHA `05816ccb9be5caea862dbe3e0fc45fc2068ff06cd049f2dda3459492d0ef7d88`, eleven controlled isolation/error/CLI cases and 59 QEMU argument fixtures. Those broad checks were not all repeated here. The review's real Cargo compilations and deny-removal controls directly cover the changed contract; a duplicate broad suite or guest smoke would add little for this behavior-preserving lint delta. + +### Documentation + +**No actionable finding.** The CI guide documents both exact probe commands, their isolated images/targets and the meaning of expected rejection. T-032 classifies every exception group and distinguishes the original baseline, local gates, hosted evidence and pending distinct review. Task, index and all three live current-focus pointers agree on In Review on development; no Done, merge or final-PR approval is inferred. + +UNSAFE-2026-0025 gains one dated amendment identifying actual implementation SHA `c3f32c8`, operation, unchanged invariants, rejected unnecessary allowance and explicit runtime-verification limit. Independent byte comparison confirms all original entries and prior amendments remain intact. Existing historical SMP-forward claims are expressly excluded and retained under T-069 ownership. The audit's pending-security sentence is honest at the reviewed tip and requires append-only completion recording after approval. No standard or Accepted ADR body is rewritten; this implements existing error-handling discipline under Accepted ADR-0040, and T-052 retains standards-reality wording ownership. There is no new architectural or policy decision requiring a new ADR. + +### Integration + +**Clean for the delta.** Both new probe steps run after the corresponding positive lint in existing required jobs, without `continue-on-error`. Workflow job names, action pins, permissions, triggers and workspace membership are unchanged. The copied toolchain file selects the same nightly outside the original checkout's directory override. Debug/release/perf coverage is retained; BSP probe image construction occurs only in its own copy and cannot disturb the production debug → release → restored debug sequence. + +Direct inspection of parent-downloaded `/tmp/tyrne-b21-step5/hosted-run.json` identifies completed success at exact executable/audit tip `b6572cc65857b99f3ac3661b99cea809a7b12e88` with all five jobs successful: [hosted run 38181326486](https://github.com/HodeTech/Tyrne/actions/runs/38181326486). Inspected supplied fast-lane line 202 records intended HAL rejection at exit 101; kernel lines 213–214 record the private 117-byte image and intended BSP rejection. Kernel lines 173/244/276 corroborate production image sizes 117 → 69 → restored 117; metadata records release and perf compilation/lint steps successful. Fast-lane summaries corroborate 366 debug and 356 release passes with the two ignored doctests excluded. The reviewer inspected these supplied files but did not independently fetch GitHub logs. + +Parent additionally reports all five jobs green at exact docs-only reviewed tip `4f2c38c` in [run 38181458269](https://github.com/HodeTech/Tyrne/actions/runs/38181458269). This is coordinator-fetched metadata attribution, not a separate API fetch by this reviewer. There is no executable delta between the first detailed hosted evidence and reviewed tip. These are development results; post-merge main, final PR review and hosted guest smoke are not inferred.

Read relevant complete preflight and T-030/T-037 code records, T-032 task/approved sequence, actual probe, full executable diff and attached exception functions, MMU root/value/walker contracts, build helper/BSP build script/Cargo configuration and affected workflow ordering, changed guide/status/audit material, commits and supplied hosted metadata/log excerpts, then the full completed paired Round 1 security report. Existing cap-unmap and rollback test contracts were inspected as complementary evidence after the primary probe-first review. + +This is a focused code review, not a whole-repository unsafe re-audit or security pass. No shared image/kernel ELF write, repository/GitHub edit, branch mutation, commit, independent broad host/Miri/stable suite, guest QEMU run, hardware/SMP test, performance measurement, signal/kill cleanup stress test or full historical-anchor audit was performed. Existing HIGH T-038 remains excluded and unaffected; host tests/Miri/lint success cannot certify its assembly soundness.

No syscall or assembly implementation change. +- **Security-review cross-reference:** distinct [security artifact](../security-reviews/2026-10-12-t032-panic-family-denies.md). Full completed Round 1 code and security reports were read; their explicit approval of changed UNSAFE-2026-0025 reasoning is now truthfully recorded append-only. The completed independent Round 2 security report was read in full at `/tmp/tyrne-b21-t032-round2-security.md`: **Approve**, no actionable finding, explicit changed 0025 approval and verified actual Round 1 recording. Parent owns its canonical publication and completed-pair recording. +- **Procedure:** `perform-code-review`, `conduct-review`, all five master-plan axes, complete code-review checklist and P1–P12. `justify-unsafe` was consulted for changed reasoning. Task/acceptance criteria and actual negative-probe harness were read before implementation, followed by configuration/types, full affected walker, callers/attached exception function bodies, workflow and evidence documents. Parent owns canonical publication/index/trailer/history; this reviewer writes only temporary verification evidence and this report. + +### Correctness + +**No actionable finding.** Each of HAL and BSP gains the three intended crate-root denies, with no weakening of existing kernel/workspace lint enforcement. HAL has no exception; syscall and MMU paths have no panic-family allowance. No runtime panic, public API, error variant, capability operation or fault-policy change is added. + +The ten exception groups were inspected as multiline attributes and with their full attached function bodies: + +| Functions | Allowed lints | Classification | +|---|---|---| +| `main::kernel_main_high` | expect, panic | One-shot trusted boot: static image/configuration, fixed-capacity objects, table/arena initialization and scheduler population before start | +| `perf_bench::run` | expect, panic | One-shot trusted measurement setup: static image, object/cap creation and publish-before-start order | +| `main::idle_entry` | expect | Trusted post-start scheduler invariant, accurately described as such rather than initialization | +| `main::task_a`, `main::task_b` | expect, panic | Existing trusted one-round kernel IPC demo with fixed capabilities and rendezvous protocol | +| `perf_bench::driver_yield` | expect | Trusted post-start current-task invariant | +| `perf_bench::driver_send`, `perf_bench::partner_recv` | expect | Statically provisioned SEND/RECV caps and fixed benchmark protocol | +| `exceptions::irq_entry` | panic | Existing fatal unhandled-IRQ branch after EOI; timer/spurious return paths preserved | +| `exceptions::panic_entry` | panic | Existing fatal unhandled-exception policy | + +Every group is function-scoped and has a concrete `reason`. None permits unwrap. No new crate/module exemption appears. Reasons neither label live syscall input as boot nor promise task-fault containment that the existing BSP does not implement. Non-SVC fatal behavior remains unchanged; no future-phase assignment or expanded policy approval is inferred. Assertions are outside these three Clippy lints, as the guide explicitly explains. The change enforces three source-level lints, not absence of all panic mechanisms. + +`QemuVirtMmu::unmap` still performs the VA alignment check and invokes `walk_and_install_leaf` with the identical root, VA, flags, null provider and literal `true`. The third argument changes from an infallible aligned-zero frame construction/unwrap to a copy of the existing typed root. `PhysFrame` is a Copy aligned-address wrapper, not an ownership token. No new reference, pointer dereference, allocation or authority arises from copying it. + +I traced the complete helper, including all intermediate success/error branches. Each intermediate call receives the unchanged `unmap` selector, returns typed missing/block errors without allocating when true, and never sees `pa`. The true L3 arm reads the current leaf, extracts its masked PA, clears the slot and returns the descriptor-derived frame. The parameter `pa` occurs only in the false/map arm's descriptor encoding and return. Consequently the substituted value cannot affect descriptor accesses, errors, returned frame, allocation, ordering or caller flush obligations on this literal-true call. The kernel `cap_unmap` caller retains authorization/arena resolution before mutation and discharges the returned flush token before returning the frame. + +**Reviewed `unsafe` in `bsp-qemu-virt/src/mmu.rs:307–333`, including the changed call/comment at :319–328; agree with and explicitly approve the changed SAFETY reasoning under UNSAFE-2026-0025.** Reusing an already-valid typed value for a genuinely ignored argument removes an unnecessary panic-family expression without an MMU allowance or broader unsafe scope. Existing valid-root, exclusively owned table lifetime, direct-map and index-bound obligations remain load-bearing. This approves the delta, not every historical table-walker or SMP claim. + +The probe adds `black_box(None::).unwrap()` in non-test crate-root code outside allowances and requires nonzero exit plus the exact `clippy::unwrap_used` diagnostic. It rejects success or unrelated failure alone. Actual host/kernel aliases select the intended packages/targets and retain `-D warnings`. The BSP builds source-derived userland inside its copied tree before probing, preventing missing-image failure from serving as lint evidence. The existing NUL-delimited copy loop preserves tracked filenames and modes; a fresh private target prevents stale compiler results; EXIT cleanup covers observed normal/error exits. No shared image/kernel output is written. + +### Style + +**Clean.** Independent Bash syntax checking, default-severity ShellCheck and range whitespace validation pass. Rust attributes follow existing conventions with explicit reasons. No toolchain/target flag/dependency change, unrelated refactor, broad suppression or style churn appears. Changed prose and conventional commit subjects are English. All four commits carry valid `Refs: ADR-0040`; implementation/audit reconciliation/actual review recording carry `Audit: UNSAFE-2026-0025` where applicable. The final recording commit names the real distinct reviewer and existing artifact in `Security-Review:`; it does not retroactively claim the implementation had an approval that was then pending. + +### Test coverage + +**Adequate for the scoped enforcement change; no missing blocking test.** The persistent tests exercise the exact real Clippy commands, rather than a synthetic string search or alternate flags. Existing fake-MMU `cap_unmap_returns_unmapped_frame` checks returned PA and both TLB invalidations, while rollback tests cover kernel-level leaf reclamation. Those contracts are complementary evidence, not execution of this BSP walker. No public API/Error variant was added. Static ignored-parameter equivalence supports the only runtime expression substitution; the ordinary smoke does not exercise BSP unmap. + +Fresh independent checks in this round used the pinned nightly, `/bin/bash`, Python `TemporaryDirectory` roots with spaces and private target/source trees: + +| Check | Observed result | +|---|---| +| Real `tools/test-ci-gates.sh --hal` | Harness 0; actual host Clippy 101 with `clippy::unwrap_used`; private probe root removed | +| Real `tools/test-ci-gates.sh --bsp` | Harness 0; private 117-byte image built; actual kernel Clippy 101 with intended unwrap lint; private probe root removed | +| HAL root expect probe in tracked private snapshot | Exact `cargo host-clippy` 101 with `clippy::expect_used` | +| BSP separate panic helper called by panic-allowed `task_a` | Exact `cargo kernel-clippy` 101 with `clippy::panic`; caller allowance does not propagate to callee | +| Perf separate expect helper called by expect-allowed `driver_yield` | Exact feature-aware perf Clippy 101 with `clippy::expect_used`; caller allowance does not propagate to callee | +| Additional BSP panic helper called by idle | Exact kernel Clippy 101 with `clippy::panic` | +| Audit historical-byte comparison | Removing only both T-032 additions (2,571 bytes) restores `8591ceb` log exactly | +| Shared source/image and cleanup | HAL/BSP root SHA-256 and existing hello SHA unchanged; outer snapshots/targets removed | +| Script syntax, ShellCheck, range whitespace | All exit 0 | + +Logs and machine-readable results: `/tmp/tyrne-b21-t032-round2-code-checks/`. The same-lint panic-callee control specifically uses `task_a`, whose caller permits panic; the extra idle-callee case alone would not establish this same-lint property. No failed fixture is counted as a passing check. The shared debug image remains SHA-256 `05816ccb9be5caea862dbe3e0fc45fc2068ff06cd049f2dda3459492d0ef7d88`. + +Full Round 1 reports separately record fresh real unwrap probes, deny-removal controls and expect/panic rejection in both crates. These were read as prior independent evidence, not represented as this reviewer's executions. Parent-supplied implementation checks cover fmt/actionlint, host/default/release/perf builds and Clippy, 366 host and 366 Miri passes with existing warnings/two ignored HAL doctests, real debug greeting/exit/completion/two SVCs/no fault class, eleven controlled probe/CLI cases and 59 QEMU argument cases. This round did not repeat those broad suites or guest smoke without a source concern. + +### Documentation + +**No actionable finding.** The guide matches the two exact commands, private BSP image construction and meaning of expected rejection. Task history enumerates all ten classifications, differentiates baseline/local/hosted/review evidence, and correctly retains In Review. The index/current focus and review history preserve second-round/final maintainer PR pending state, with no Done or merge claim. + +The actual implementation SHA in the dated 0025 amendment resolves to `c3f32c8`; the amendment states the operation, unchanged invariants, rejected allowance and runtime/SMP limits. The appended actual Round 1 recording matches the full source reports: both explicitly approve the changed argument reasoning and the distinct security report has a scoped Approve verdict. The historically pending sentence remains intact and is completed by a subsequent truthful record. Independent comparison proves original entries and every earlier amendment are byte-preserved. The retained historical SMP-forward claim is expressly excluded, with T-069 owning that work. No standard or Accepted ADR body is rewritten. Existing error-handling policy under ADR-0040 supplies the decision; T-052 retains standards/reality wording ownership. + +### Integration + +**Clean for the delta.** New CI steps follow the corresponding positive lints in existing jobs without `continue-on-error`. Required job names, action pins, permissions, triggers, workspace membership, lockfile and toolchain are unchanged. Copied toolchain/config select the same nightly/aliases outside the checkout override. Private BSP image/targets cannot disturb the production debug → release → restored debug sequence. No executable source changes occur after `c3f32c8` in the reviewed range. + +I inspected parent-downloaded `/tmp/tyrne-b21-step5/hosted-run.json`, `hosted-fastlane.log` and `hosted-kernel.log`.

Read coverage and procedure + +Read `AGENTS.md` and `CLAUDE.md` in full before reviewing implementation, followed by `docs/roadmap/current.md`, all 39 numbered ADRs in numerical order (`0001`–`0040`, excluding reserved/unwritten `0034`), and all 15 files under `docs/standards/`.

Read T-033's intent and acceptance criteria, then the complete new test harness **before** the implementation. Reviewed the complete runner scripts, Cargo configuration, all changed Markdown documents and the workflow's affected job/context. Inspected the entire range's diff and both commit messages. + +Supporting source reads included `tools/build-userland.sh`, `bsp-qemu-virt/build.rs`, and the locations of the documented runtime markers. + +No tracked files, commits or branches were changed during the review. Negative experiments used disposable temporary copies. This report was subsequently saved at the root reviewer's explicit request. + +### 3. Correctness + +**Clean.** + +Both runners implement the documented precedence: the last `--smp N`, then `QEMU_SMP`, then `1`. Validation occurs after parsing, allowing a valid explicit flag to override an invalid or empty environment value. Invalid final values fail before QEMU or default builds run. + +Missing `--smp` and `--timeout` operands produce usage diagnostics and exit `2`, without accessing an unset `$2`. Both scripts preserve an explicit ELF containing spaces as one argument. The smoke script now rejects additional positional ELF arguments consistently. + +The regex validates decimal text directly rather than performing shell arithmetic, avoiding arithmetic interpretation or overflow during validation. Very large positive decimal text is forwarded unchanged; this proves argument handling, not QEMU acceptance of that core count. + +Independent boundary probes covered whitespace, newline, leading zero, plus sign, repeated valid/invalid flags, empty environment override, help with an invalid environment, missing operands and repeated timeout options. + +### 4.

Syntax and diff checks passed. A separate test run placed a `/bin/bash` symlink first on `PATH`, forcing the harness and both runners' `#!/usr/bin/env bash` invocations onto Bash 3.2; all 59 cases passed. + +The new harness has executable mode `100755`. New repository prose and commit messages are English. Both commits follow the existing Conventional Commits convention and contain `Refs: ADR-0040`. + +### 5.

Integration and existing findings + +**Clean for this range.** + +The permanent argument suite is in the existing required fast lane, needs no real guest or kernel build, and adds no framework or dependency.

This review makes no kernel soundness or SMP-support claim. +- **Verdict:** **Approve within this review’s scope. No actionable new finding.** + +### Correctness + +The parser changes implement the agreed contract: + +- Both helpers pass the selected core count as one quoted QEMU argument. +- Precedence is the last `--smp N`, then `QEMU_SMP`, then `1`. +- An empty environment value is rejected; a valid flag overrides an invalid environment default. +- Missing final values, invalid counts/budgets, unknown long flags and extra ELF arguments return 2 with usage. +- Invalid input is rejected before building or launching QEMU. +- Explicit ELF paths containing spaces survive argument forwarding. +- Default and release profile paths remain correct. + +Mixed-error behavior is consistent with the implementation: argument-loop errors precede final value validation; SMP validation precedes timeout validation. For example, `--smp 0 --unknown` reports the unknown flag, while `--smp 0 --timeout bad ` reports the SMP error. Help exits immediately when encountered; using `--help` as a consumed SMP value produces the numeric-validation error. These behaviors introduce no contradiction with the agreed task contract. + +Independent isolated probes also confirmed that default smoke builds userland before the kernel, passes `--release` to both builds when selected, and skips both builds for an explicit ELF. All build commands in those probes were stubs; the shared source tree and `hello.bin` were untouched. + +### Style + +The changes follow the existing Bash style and retain Bash 3.2 compatibility. `bash -n` passes for both helpers and the new regression harness. + +ShellCheck returns 1 solely for the existing `smoke.sh` comma-token warning: + +```text +tools/smoke.sh:43 — SC2054 — INT_FLAGS=(-d int,unimp) +``` + +Neither the new harness nor `run-qemu.sh` produces a finding. This is the explicitly accepted immediate T-031 carry-forward, not a new defect. + +`actionlint -shellcheck=''` returns 0. Existing workflow `NIGHTLY_PIN` quoting findings remain assigned to T-031; disabling ShellCheck integration here establishes workflow/schema validity only. + +Both commits use the expected subject format and contain `Refs: ADR-0040`. `git diff --check 3a7c264..d5c13a0` passes. + +### Test coverage + +Independent executions: + +| Check | Result | +|---|---| +| `tools/test-qemu-tooling.sh` | PASS, 59 cases | +| Same harness with a restricted base-utility `PATH`, without real Cargo/QEMU | PASS, 59 cases | +| Additional disposable-copy CLI/profile/platform probes | PASS, 31 cases | +| `bash -n tools/run-qemu.sh tools/smoke.sh tools/test-qemu-tooling.sh` | Exit 0 | +| `shellcheck tools/run-qemu.sh tools/smoke.sh tools/test-qemu-tooling.sh` | Only existing SC2054; exit 1 | +| `actionlint -shellcheck=''` | Exit 0 | +| Changed Markdown relative links and anchors | 240 targets, including 24 anchors, resolve | + +The additional 31 probes used temporary copies of the two helpers, empty ELF fixtures, logging Cargo/userland/QEMU stubs, and a restricted `PATH` selecting the Perl fallback.

It does not assert every QEMU operand, actual watchdog duration, guest faults or real SMP operation. Its explicit-ELF cases also do not cover default build ordering/profile selection; the independent probes covered those paths without a real build. These are scope limits, not acceptance failures. Runtime strengthening and negative guest probes remain T-034 work. + +I did not run real builds, write the shared userland image, or independently repeat Cargo’s runner-echo command because that command may build. The Cargo alias/static-runner source agrees with the documented override; the task’s recorded runner-echo evidence belongs to the implementer. + +The parent additionally supplied successful hosted CI for `d5c13a0`, including the new 59-case step: [CI run 38176428435](https://github.com/HodeTech/Tyrne/actions/runs/38176428435). This is supplied hosted evidence, not an independently inspected run in this pass. + +### Documentation + +The revised QEMU guide gives a coherent path from checkout to debug boot: + +- It requires the userland build before the BSP embeds `hello.bin`. +- It specifies matching profiles and rebuilding debug userland after release. +- It distinguishes the interactive helper from smoke’s build-and-run behavior. +- It explains completion followed by WFI and the QEMU exit controls. +- It describes debug greeting, task exit and completion, with the release greeting difference. +- It documents shell-helper precedence and Cargo’s explicit runner override. +- It keeps Cargo’s static runner at one core and clearly states that larger core counts are unsupported by today’s kernel. + +The documented prerequisites match `rust-toolchain.toml`, `tools/build-userland.sh` and the Cargo aliases. The guide accurately limits the existing smoke gate to completion/fault checks and assigns stronger EL0 marker enforcement to T-034. + +Task status, task index, current active task and guide refresh state remain **In Review**. The new text does not promote T-033 or T-037 to Done or imply that the required fresh rounds/final maintainer PR review have already completed. + +All 240 actual relative Markdown links in the six changed Markdown files resolve, including 24 anchors. Inline and fenced code examples were excluded; a first naïve scan identified the literal `` `](...)` `` example as a link, which was corrected in the checker. + +### Integration + +The new test step runs in the existing fast lane and requires no real QEMU, Rust compilation or new package/framework. Its dependencies are Bash, ordinary filesystem/text utilities and either `timeout` or Perl. The native 59-case run exercised GNU `timeout`; the isolated 31-case run exercised Perl. A restricted base-utility `PATH` also ran the committed harness successfully without real Cargo/QEMU availability. + +No action pins, permissions, cache keys, branch protection or external dependency declarations change. The new regression is blocking through the existing job rather than a separate required-status name. + +The full existing smoke gate still has the preflight-recorded EL0-evidence limitation. This diff neither introduces that limitation nor claims to close it; T-034 owns the stronger runtime gate. + +#### Code-review checklist + +| Checklist item | Assessment | +|---|---| +| Correctness and boundary conditions | Pass; parser, precedence, errors, quoting and profiles checked | +| Capability semantics | Not affected | +| Fault containment | Usage errors stop before launch/build; guest mechanisms unchanged | +| Unsafe discipline | No `unsafe` or assembly change | +| Error handling | Pass; required usage failures return 2 without shell-internals errors | +| Tests | Pass; committed harness and independent probes, limits recorded | +| Documentation | Pass; guide, CI mapping, links and lifecycle checked | +| Architectural principles | Consistent; no SMP/runtime support claim | +| Dependencies | No new external dependency or framework | +| Naming/style | Pass, with explicitly deferred baseline SC2054 | +| Commit messages | Pass; both commits include ADR-0040 references | + +#### Read coverage and execution boundaries + +Read the canonical `AGENTS.md` and `CLAUDE.md`, complete `current.md`, all 39 existing numbered ADRs (`0001–0033`, `0035–0040`; `0034` has no file), all standards including their index, skills index, `perform-code-review`, `conduct-review`, the code-review master plan, T-033 and the Track B.2-1 preflight review.

Read the preceding Track B.2-1 preflight and full round-1 reports as context without treating their verdicts as this review's evidence. Reviewed every changed file and hunk in the 13-file range, including the new review record, all three commit messages, both complete runners, Cargo configuration and the affected fast CI lane. Supporting reads covered the complete userland builder, BSP build script, toolchain pin and source locations for the documented runtime markers and target gates. + +The five review roles below were performed sequentially in this independent pass. No repository source/document edit, commit, branch operation or external message occurred. Disposable copies and stubs were created outside the repository. The only real build was the authorized default debug smoke path; no alternate-profile userland image or multi-core guest was built/run. The requested report was saved in `/tmp`; repository publication/index reconciliation belongs to the root reviewer. + +### Correctness + +**Clean.** Both runners implement the stated last-flag/environment/default precedence and validate the final value before build or QEMU side effects. The `${QEMU_SMP-1}` expansion distinguishes an unset environment default from an invalid empty value; an explicit valid flag can override either invalid environment text or an earlier invalid flag. Positive decimal validation does not evaluate untrusted text as shell arithmetic. + +The new operand guards prevent an unset `$2` read. Missing operands, invalid counts/budgets, unknown long flags and extra ELF arguments produce usage errors with exit 2. The interactive runner's conversion to a consuming `while` loop advances every successful non-exit branch. Quoted array/argument forwarding preserves an explicit ELF containing spaces and passes the selected SMP value as exactly one operand. The default remains `-smp 1` in both helpers and Cargo's static runner. + +Independent boundary probes covered leading zeroes, signs, surrounding whitespace, embedded newline/tab, comma-separated text, shell-metacharacter text, invalid final repetition, valid overrides, help precedence, missing values and a positive integer larger than a machine word. The large value is forwarded literally, not promised to be accepted by QEMU. Isolated default-profile checks verified userland-before-kernel build ordering, matching release flags and the selected debug/release ELF paths without changing the shared userland image. + +### Style and portability + +**Clean for introduced code.** On macOS, `/bin/bash` reports **3.2.57**. Syntax checking passed for both runners and the new test script. Independent runner probes used `/bin/bash` directly, and their QEMU stubs confirmed Bash 3.2 execution. A restricted `PATH` with a `bash` symlink to `/bin/bash` also forced the permanent harness and its child scripts onto Bash 3.2; all 59 cases passed. + +`git diff --check 3a7c264..eede01c` passed. The permanent harness has executable mode `100755`. New prose and all three commit messages are English.

T-034 owns stronger debug/release marker enforcement and negative guest probes. This pass did not repeat unrelated broad Rust suites or Miri, and does not independently certify the prior round's mutation-test results. + +### Documentation + +**Clean.** The guide's commands and explanations agree with the builders, Cargo aliases and runtime markers: matching-profile userland precedes the kernel build; interactive helpers run existing ELFs; smoke builds when no explicit ELF is supplied; completion is followed by WFI; release console rejection does not prevent exit/completion. The shell and Cargo override workflows are explicit, and the Cargo echo override was independently exercised. + +The core-count section documents last-flag/environment/default precedence, empty-value rejection and valid explicit overrides. It clearly labels N > 1 as unsupported preparation for Phase C, with no secondary-core park guard or bring-up claim.

The final regex validates decimal text without shell arithmetic and rejects zero, signs, leading zeroes, whitespace and non-digits. Very large decimal text is passed unchanged; QEMU's acceptance of that count is not established by these checks. + +The argument loops consume each argument or exit. Missing `--smp` operands, and the missing `smoke.sh --timeout` operand, return 2 with a flag-specific diagnostic and usage, without an unset `$2` access. Final invalid values stop before default builds or QEMU launch. Both helpers reject extra ELF arguments, and quoted explicit paths containing spaces remain one QEMU operand. Help exits immediately when encountered as a flag; when consumed as a numeric operand it is rejected. Repeated timeout operands use the last value, consistent with the existing parsing pattern. + +Independent copied-runner probes confirm that the default debug and release ELF paths remain correct. Default smoke builds userland before the kernel, forwards `--release` to both builds when selected, and skips both builds for an explicit ELF. The interactive helper only runs an existing ELF. These probes used empty ELF fixtures and logging build/QEMU stubs; no shared `hello.bin` was written. + +### Style + +**Clean for introduced code.** The changes follow the surrounding Bash conventions, retain Bash 3.2 compatibility and add no unrelated refactoring. `/bin/bash` is 3.2.57 on this host. Syntax checks pass for both helpers and the regression script. The permanent 59-case suite also passes with a `/bin/bash` symlink first on `PATH`, forcing the harness and its env-shebang children onto Bash 3.2, when invoked from outside the checkout. + +The harness is tracked executable (`100755`). New repository prose and all three commit messages are English. All three subjects follow Conventional Commits and include `Refs: ADR-0040`. `git diff --check 3a7c264..eede01c` passes. + +Local ShellCheck exits 1 solely for the unchanged `smoke.sh` SC2054 expression `INT_FLAGS=(-d int,unimp)`. Full actionlint exits 1 with 16 existing SC2086 reports on workflow `NIGHTLY_PIN` expansions. The two-line workflow delta adds only the new test step; those expansions predate T-033. `actionlint -shellcheck=''` exits 0 and establishes workflow/schema validity only. These are the explicitly recorded, immediately following T-031 carry-forwards, not introduced findings and not a claim of clean full lint. + +### Test coverage + +**Adequate for T-033.** Read the complete new regression harness before the helper implementations. It checks observable exit status, diagnostic content, no QEMU launch on usage errors, the selected SMP operand, and preservation of an explicit ELF containing spaces.

Smoke-specific probes covered repeated timeout validity, a flag consumed as timeout, bare timeout, and an actual Perl fallback selected through a restricted utility `PATH` with no `timeout`, real Cargo or real QEMU exposed. Logging assertions established build order, profile forwarding and the absence of build/launch side effects for usage failures. + +Limits are explicit: the permanent suite uses explicit ELF fixtures and does not itself cover default build order, profiles, real watchdog duration, guest faults or EL0 execution. This round independently covered the build/profile contracts through copies and selected the real Perl path, but did not measure watchdog duration. Runtime marker strengthening and negative guest traces remain T-034. No real build, real QEMU, alternate-profile image or multi-core guest was run by this reviewer; the parent assigned real default smoke to the other independent reviewer. The source/default-path probes do not substitute for that runtime evidence. + +### Documentation + +**One Low, non-blocking finding.** + +**R2-INT-01 — The refreshed guide inaccurately describes the post-completion loop as WFI.** `docs/guides/run-under-qemu.md:73` newly says “The completed kernel idles in WFI”. In the current default demo, `task_a` prints completion at `bsp-qemu-virt/src/main.rs:723`, prints timing, then immediately enters `loop { core::hint::spin_loop(); }` at lines 742–744 without yielding or exiting. The source explicitly documents at lines 533–537 that the WFI idle fallback is structurally unreachable in the demo path. The old guide described a spin loop; this refresh introduces the inaccurate WFI claim. Existing smoke/perf WFI comments predate this range and are not additional introduced findings. The practical instructions to exit QEMU and use a watchdog remain correct, so this is Low and non-blocking. **Requested correction:** say the kernel continues running/spins after completion and does not exit QEMU itself; change no guest behavior. + +The guide otherwise supplies a coherent checkout-to-debug-boot sequence: matching-profile userland first, then kernel, then interactive boot. The prerequisites agree with the pinned toolchain, `tools/build-userland.sh`, the BSP's existence/change checks and Cargo aliases. QEMU's exit controls and the need for a bounded noninteractive run are correctly described; the WFI mechanism needs the narrow wording correction above. The current EL0 greeting, task-exit and completion markers replace the obsolete first-kernel-greeting workflow. Release greeting absence is explained, together with rebuilding debug userland before returning to debug. + +The core-count section documents last-flag/environment/default precedence and invalid-value behavior. Both help headers explain the new option and precedence. The guide and helper headers explicitly say that counts above one are unsupported by today's kernel; the static Cargo runner remains `-smp 1`. The Cargo environment override is shown with both the shell helper and `echo`, and source inspection confirms that Cargo supplies the ELF path to that runner. I did not repeat `cargo kernel-run` because it may build; its recorded implementation/round-1 execution is separate supplied evidence. + +The guide accurately describes the current smoke gate as completion/fault checks and links T-034 for stronger debug/release EL0 enforcement. It does not claim the new stub CI step boots a guest. T-033, its task index, current focus, guide refresh and review index remain `In Review`/round-2-pending at this snapshot. No agent review is represented as maintainer permission to merge or mark Done. The round-1 artifact and hosted result are historical evidence, and the second-round evidence is intentionally not preclaimed. + +Checked actual relative Markdown destinations in all eight changed Markdown files, excluding inline and fenced code examples: **255 targets, including 24 anchors, resolve; zero failures**. External web destinations were not fetched in this local review. + +### Integration + +**Clean for this range.** The dependency-free, executable harness runs in the existing required fast job, with no `continue-on-error`, conditional skip, additional framework, new action or permissions change. It needs Bash, normal text/filesystem utilities and either timeout or Perl. The required job's status name remains unchanged, so the new check inherits that existing gate rather than requiring a new branch-protection name. The workflow uses checkout-root execution, matching the harness's own repository-root resolution. + +Cargo's static single-core runner, build aliases, action pins, caches, permissions and guest implementation remain unchanged. `tools/perf-harness.sh` continues to receive the environment default through `run-qemu.sh`; no new perf flag is required by T-033. The documented release/default build sequencing agrees with the unchanged userland embedding pipeline. The explicit-ELF smoke contract remains build-free. + +Hosted CI is **supplied evidence, not independently fetched in this pass**: the task history and parent report [CI run 38176428435 at `d5c13a0`](https://github.com/HodeTech/Tyrne/actions/runs/38176428435) successful, including PASS59 in the new fast-lane step. `eede01c` adds review/lifecycle documentation rather than an additional executable change. I did not independently rerun Rust fmt/clippy/host-test/Miri gates; the range changes no Rust and those results remain author/hosted evidence. + +### Full code-review checklist + +| Item | Assessment | +|---|---| +| Correctness | Pass; parser, precedence, validation, forwarding, defaults and build order checked | +| Capability semantics | Unaffected; no guest authority boundary change | +| Fault containment | Usage errors precede build/launch; guest fault mechanisms unchanged | +| `unsafe` discipline | N/A; no `unsafe` or audit-log change | +| Error handling | Pass; required usage errors return 2 without shell internals | +| Tests | Pass for scoped tooling; permanent suite, independent probes and baseline regression reproduced; runtime limits stated | +| Documentation | Minor; R2-INT-01 corrects the new WFI wording; help, CI mapping, local links/anchors and lifecycle otherwise pass | +| Architectural principles | P1–P7 unaffected; P8 follows Accepted ADR-0040; P9 English; P10 no new diagram; P11 pins/dependencies unchanged; P12 completes the scoped tooling contract without claiming SMP support | +| Dependencies | None added; no add-dependency procedure triggered | +| Naming/style/portability | Pass for introduced code; Bash 3.2; baseline lint carry-forwards explicitly identified | +| Commit messages | Pass; all three conventional subjects and ADR-0040 references | +| CI/caller integration | Pass; existing required fast-lane job; static Cargo runner unchanged | +| Security review | Separate security artifact not required for this ordinary scoped delta | +| Artifact/index publication | Parent owns repository append/index/history updates; this reviewer was explicitly restricted to a temporary report | + +### Read coverage and boundaries + +Read AGENTS/CLAUDE and complete current focus; all 39 existing numbered ADRs in numerical order (`0001–0033`, `0035–0040`; `0034` is reserved/unwritten), all 15 standards including their index, the skills index, both applicable review skills, full code-review master plan, preflight review and complete T-033 round-1 artifact.

The implementation source is unchanged by that follow-up. +- **Reviewer:** Codex independent CODE reviewer, agent `b21_step6_round1_code`, performing all five code-review roles separately from the SECURITY reviewer. +- **Risk class:** Security-sensitive verification infrastructure: this establishes a merge gate for boot/EL0/syscall behavior, although it changes no production Rust, assembly, capability implementation or unsafe region. +- **Security-review cross-reference:** `/tmp/tyrne-b21-t034-round1-security.md`, independent agent `b21_step6_round1_security`, **Changes requested**. This CODE reviewer read the completed report in full (all 189 lines) before issuing the final verdict. Its SEC-T034-R1-01 is the same independently reproduced HIGH pipeline defect; its eight axes/33 items/P1–P12 establish no other new actionable security finding. + +### Correctness + +#### CODE-T034-R1-01 — HIGH — CI discards the production smoke failure through `tee` + +**Locations:** `.github/workflows/ci.yml:237` and `.github/workflows/ci.yml:243` (the debug and release production smoke `run` pipelines). + +Both steps run `tools/smoke.sh ... 2>&1 | tee ...` without a step `shell: bash`, a job/workflow `defaults.run.shell`, or `set -o pipefail`. On Linux the unspecified Actions shell invokes `bash -e {0}`; explicitly selecting Bash invokes `bash --noprofile --norc -eo pipefail {0}`. GitHub documents this distinction in its [workflow syntax reference](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax#jobsjob_idstepsshell). The child smoke script's own `set -euo pipefail` does not set options in the enclosing workflow shell. + +**Impact:** A missing required marker, forbidden release greeting, panic/fault trace, or another smoke-script failure can print `FAIL` and exit nonzero while `tee` successfully saves the log and makes the production step succeed. The subsequent negative harness invokes the smoke script directly via `subprocess.run`, so its 23 passing cases do not prove that the production workflow propagates failures. A green hosted run of the clean kernel does not establish that a bad production guest blocks merging. This violates the core T-034 merge-gate acceptance criterion. + +**Independent proof:** A disposable QEMU stub emitted only `tyrne: all tasks complete`; the actual unmodified `tools/smoke.sh --int --timeout 1 ` printed both missing greeting and missing task-exit diagnostics. Wrapped in the production-equivalent pipeline, `bash -e` returned **0**. The identical pipeline under `bash --noprofile --norc -eo pipefail` returned **1**. Evidence: `/tmp/tyrne-b21-t034-round1-code-pipeline.json`. The SECURITY reviewer first raised the candidate; this CODE reviewer independently reproduced it with the actual smoke entry point and checked the official shell contract. + +**Required correction:** Enable `pipefail` for both production pipelines, preferably through job-scoped `defaults.run.shell: bash` or explicit `shell: bash` on both steps. Add a focused regression that exercises a deliberately rejected smoke trace through the workflow's effective shell and `tee`, asserts a nonzero enclosing result and the intended smoke diagnostic, and retains the diagnostic artifact. Testing only direct smoke subprocess exit codes misses this integration defect. + +#### Other correctness checks + +The smoke implementation itself uses exact whole-line fixed-string checks for debug greeting/task exit/completion, requires task exit/completion in release, and forbids the greeting anywhere in release output. Explicit ELF paths skip rebuilding; profile expectations are explicitly selected by `--release`, not guessed from the pathname. The existing six panic/fault patterns remain active. Two expected SVC exceptions are not treated as faults; exact SVC counts and adversarial images are explicitly separate task scope. + +The three actual mutations have distinct intended effects. EL0 omission bypasses only scheduler publication while retaining kernel completion; completion omission alters only that marker; release-greeting injection occurs at kernel completion to challenge the forbidden-output contract without changing syscall behavior. Anchor-count checks fail closed on source drift. Exact observed marker shapes plus absence of unrelated faults prevent accepting an accidental boot failure as successful mutation evidence. + +No additional actionable correctness finding was verified. Existing HIGH T-038 assembly clobber debt is unchanged, excluded from this change, and neither cleared nor downgraded by these smoke results. + +### Style + +No actionable style finding. The small shell entry point delegates to a Python stdlib harness; local functions keep case/build/evidence handling together without adding a crate or host package dependency. Repository prose, comments and diagnostics are English. SHA-pinned actions have version comments; the existing pinned Rust toolchain is retained. Formatting, clippy and ShellCheck are covered by supplied implementation/hosted evidence and were not gratuitously rerun by this reviewer. + +### Test coverage + +#### Independently executed + +- `tools/test-smoke-gates.sh --real --artifact-dir /tmp/tyrne-b21-t034-round1-code-probes`: **23/23 passed**, comprising 20 labeled synthetic trace cases and three actual privately built QEMU kernel variants. Its JSON identifies documentation tip `41d96824d791167dc1f22beb8a9d13cb8f3c879d`, `completed: true`, and all cases passed. Actual traces independently checked for marker shapes: omission `false/false/true`, missing completion `true/true/false`, release greeting `true/true/true`, with no listed panic/fault pattern. +- Two production smokes using private copies of the already-built debug/release ELFs, private trace directories and `--int --timeout 2`: **both passed**. This reviewer did not rebuild the clean shared production ELFs. Results and traces: `/tmp/tyrne-b21-t034-round1-code-production/`. +- Eight additional private fixture cases passed: positive explicit debug/release ELFs; prefixed greeting; suffixed exit; suffixed completion; embedded release greeting; release-shaped trace under debug expectations; debug-shaped trace under release expectations. A private failing Cargo stub confirmed that explicit-ELF invocations did not rebuild. Evidence: `/tmp/tyrne-b21-t034-round1-code-edges.json`. +- A disposable harness/script copy with the positive gate intentionally forced to fail returned **1**, preserved the raw trace and partial `results.json`, recorded the first case as failed, and retained `completed: false`. This challenged harness failure diagnostics and evidence preservation, without changing repository source. +- The actual smoke/`tee` enclosing-shell rejection experiment reproduced CODE-T034-R1-01, above. +- Hashes of the shared debug/release kernel ELFs and `userland/hello/hello.bin` were unchanged across the private harness run. Before hashes: `/tmp/tyrne-b21-t034-round1-code-shared-before.json`; final comparison passed. Repository tracked tree remained clean on `development`. + +#### Inspected supplied and hosted evidence + +The pre-fix private baseline `/tmp/tyrne-b21-step6-el0-omission-baseline.json` records old smoke exit 0 despite absent greeting/task-exit and present completion. This is author-supplied historical evidence, not a pre-fix rerun by this reviewer. Combined with independently executed current omission rejection, it supports the intended regression fix at the standalone smoke layer. + +Downloaded hosted artifact evidence under `/tmp/tyrne-b21-step6/hosted-artifact/` was retrieved by the parent and read locally by this reviewer. Both complete production raw traces show the intended profile markers, no listed panic/fault pattern, and actual EL0 SVC execution. Probe JSON binds the clean source `64500055f24dd72283582ec339dee8318de96a86`, the smoke SHA-256, all 23 labeled passing cases and `completed: true`; actual probe raw traces have the intended marker shapes. Metadata identifies run `38183035717`, attempt 1, QEMU 8.2.2, pinned rustc 1.94.0-nightly, x86_64 Linux, and 96 seconds from evidence initialization to completion. The parent separately reports 101 seconds for the full job and all six jobs green. [Hosted run](https://github.com/HodeTech/Tyrne/actions/runs/38183035717). + +The artifact service's reported digest is not represented here as an independently recomputed downloaded archive checksum. This review establishes consistency of the extracted evidence with the reviewed source identity, not cryptographic attestation of the host or runner. + +Implementation evidence supplied by the parent includes fmt, host/kernel clippy, 366 host tests, actionlint, default ShellCheck, 59 existing argv cases and four final CLI cases. This reviewer did not independently rerun those broader checks. No production Rust behavior changed, and the focused guest/harness/shell experiments address the changed behavior directly. + +#### Missing regression + +CODE-T034-R1-01 requires a test of the **enclosing CI shell pipeline**. The current direct harness is otherwise meaningful, but its successful expected-failure cases do not protect that caller boundary. This is part of the single blocking finding, not a separately counted defect. + +### Documentation + +The task, current-focus and task-index status correctly remain **In Review**. Documentation explains matching profile images, `--int`, explicit release ELF expectations, synthetic versus actual probes, new artifact-directory refusal, retained partial evidence, Python/Rust/LLVM/QEMU prerequisites, 14-day artifact retention and the absence of exact SVC-count claims. Hosted evidence is identified separately from the historical Mac 4.7 ms emulated boot anecdote and from local execution. + +ADR-0040 governs this already-approved work; its accepted policy permits the reviewed development sequence and defers final maintainer promotion/PR to the proper stage. No new architectural decision or production Rust API requires a new ADR/rustdoc/safety entry. Commit messages reference ADR-0040. New review/security trailers and canonical report/index publication are parent-owned follow-up work; this read-only subagent does not fabricate completed trailers. + +The docs' intended fail-the-PR guarantee is not implemented correctly until CODE-T034-R1-01 is fixed. Live required-check registration and final-PR green evidence remain deliberately pending; they are not incorrectly counted as missing implementation already claimed complete. No separate documentation defect is raised for that temporal state. + +### Integration + +#### Workflow, harness and artifact boundaries + +The job builds matching userland immediately before each production kernel profile, uses single-core QEMU with `--int`, records QEMU/Rust/source/run identity, has a 10-minute job bound and uses always-run wall-time/upload steps. Workflow token permissions remain `contents: read`; checkout disables persisted credentials. Artifacts retain separate production raw/output logs, probe raw/output/build logs and provenance, including available early-failure evidence. No new project dependency, secret input or privileged GitHub write is introduced. + +The harness copies tracked source into a disposable tree, uses a private Cargo target directory and produces its embedded user image in that tree. It clears `QEMU_SMP` for its controlled single-core cases, uses a unique per-case trace directory, refuses existing artifact paths and requires exactly one raw trace. Python subprocess invocation uses argv arrays, not shell interpolation. Temporary source/target/image copies are removed by the temporary-directory context even on raised errors; requested artifacts survive independently. + +The critical integration failure is that the workflow's `tee` caller loses the smoke script's result. Fixing the standalone gate and proving direct negative subprocesses was insufficient to establish merge enforcement. + +#### Full code-review standard checklist + +| Item | Result and evidence | +|---|---| +| Correctness | **Fail:** verified HIGH CODE-T034-R1-01. Standalone marker/profile logic passes focused checks. | +| Capability semantics | No production capability operation or trust-boundary authorization changes.

Supplied checks and hosted evidence were inspected with provenance distinguished from independent execution. The cohesive change is 366 insertions/46 deletions across 12 files including task/guide/evidence updates; no unrelated runtime refactor is included. The preflight review was read for earlier smoke/profile findings. No completed review of this implementation round is overwritten.

Initial oversized read outputs were followed by bounded rereads of affected portions.

No repository edit, commit, branch switch or GitHub mutation was performed. Experiments used disposable source/target/image copies and private trace/artifact directories. Hosted evidence was downloaded by the parent; no assertion of independently retrieving live policy or final PR state is made. Passing single-core QEMU does not establish SMP, hardware correctness, exact SVC-count enforcement, adversarial-userland fault containment, exit-code-zero proof or resolution of deferred T-038 debt. + +### Verdict + +**Request changes.** + +Blocking finding: **CODE-T034-R1-01 (HIGH)** — propagate both production smoke pipeline failures and add a regression for the effective workflow shell plus `tee`. The standalone gate/harness behavior and positive hosted guest proof are useful and verified, but do not repair the merge-enforcement failure. + +The completed paired security report was read in full before this verdict; it also requests changes for the same HIGH defect.

Read T-034 before implementation and the test harness before its consumers; examined complete smoke/build/runner scripts, Python harness and wrappers, pipeline probe, changed workflow and surrounding environment/permission/build configuration, changed guides/standards/task/status documentation and commit messages. Read both full canonical Round 1 code and distinct security reports, preserving their historical Requests changes verdicts. + +The review range is a specific stacked development step governed by Accepted ADR-0040, not the final PR or a whole-kernel re-audit. The documentation follow-up changes six documentation/index files only; executable source is unchanged from `97a6c83`. No repository edits, commits, branch switches or GitHub writes were performed. Own mutations, build targets and generated guest images were confined to disposable private directories. Parent owns canonical publication, indexes/history, truthful trailers, later live policy apply/read-back and final PR. + +Own executions are distinguished below from coordinator-supplied downloaded hosted evidence and prior reviewers' work. The initial hosted run proves clean guest/direct-probe behavior at `6450005`; it does not prove the formerly broken production workflow propagated failed smoke. The corrected hosted run is inspected supplied evidence, not a hosted run independently launched or downloaded by this reviewer. + +### Correctness + +**Clean for the scoped delta.** `tools/smoke.sh:137` now requires exact complete debug greeting/exit/completion lines; release requires exit/completion and rejects any greeting occurrence. Both reject the existing six panic/CPU-fault patterns. Explicit ELF input deliberately skips builds; `--release` selects release expectations. QEMU's expected watchdog termination is not mistaken for a verdict: trace content decides success. No exact SVC count, zero task-exit code, exhaustive fault classification or assembly soundness is inferred. + +**Round 1 HIGH disposition — fixed.** `CODE-T034-R1-01` / `SEC-T034-R1-01` was real: successful `tee` masked smoke exit 1 under unspecified hosted `bash -e`. `.github/workflows/ci.yml:193` now sets job-scoped `defaults.run.shell: bash`; guard and both production steps inherit it, with no step override or continue-on-error. GitHub's [workflow syntax reference](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax#jobsjob_iddefaultsrunshell) documents explicit Bash with pipefail and the different unspecified-shell command. Corrected hosted logs independently inspected here show `/usr/bin/bash --noprofile --norc -e -o pipefail {0}` for all three relevant steps. + +`tools/probe-smoke-pipeline.sh` invokes the actual smoke entry point using a clearly labeled synthetic completion-only QEMU trace. It neither fabricates the rejection diagnostic nor catches/replaces smoke status. Its own pipefail does not repair the caller; job shell inheritance does. The enclosing guard at workflow line 236 rejects a successful log pipeline, then requires the actual missing-userspace-exit diagnostic, excluding an unrelated command failure as sufficient evidence. + +**Own sensitivity control:** extracted the exact workflow guard and ran it unchanged under the two shell modes, with separate private evidence/scratch directories. Broken `bash -e` makes the guard exit 1 because the smoke rejection was masked; explicit Bash with `-eo pipefail` makes the guard exit 0 because the intended rejection propagates and its diagnostic is present. Both retain real missing-greeting/exit output and leave probe scratch empty. Evidence: `/tmp/tyrne-b21-t034-round2-code-pipeline.json`. Removing pipefail therefore fails the permanent guard. The paired security reviewer separately tested unrelated missing-tool failure and found the guard rejects it; that is corroborating supplied security execution, not this reviewer's own run. + +**Harness semantics — correct.** The 20 fixtures exercise both positive profiles, every required-marker omission, each of six panic/fault patterns in both profiles and forbidden release greeting. Three real variants mutate a copied tracked tree at unique anchors, rebuild matching userland/kernel profiles into a private target, and require exit 1, intended diagnostic, intended exact marker shape and no unrelated fault. A compiler failure or unrelated boot failure cannot count as a successful negative. `QEMU_SMP` is removed for harness runs; the caller probe explicitly chooses one CPU. No SMP support is claimed. + +No new actionable correctness finding. The historical Round 1 HIGH is resolved for this corrected range, without rewriting its original verdict. + +### Style + +**Clean.** Short shell entry points retain quoting and argv handling; the Python implementation uses standard library subprocess argv lists, no shell evaluation, finite fixture/variant data and local helper functions. Names and comments distinguish synthetic fixtures, actual private kernels and production guests. Comments explain why trace status, profile ordering and inherited caller shell matter. New diagnostics and changed repository prose are English. No new Rust formatting, clippy policy, public Rust API or unsafe annotation applies. No preference-only style finding is raised. + +The existing checkout/cache pins remain intact; the newly added artifact pin is a full immutable SHA. Independently querying the official actions/upload-artifact repository with `git ls-remote ... refs/tags/v7.0.2` returned `cf430e030ddbb5b0abf93d22962f4752f3646cd9`, matching the workflow. This verifies tag/pin correspondence, not a full audit of bundled JavaScript. + +### Test coverage + +**Adequate for the declared gate and fix.** Own fresh focused execution of `tools/test-smoke-gates.sh --real --artifact-dir /tmp/tyrne-b21-t034-round2-code-probes` completed successfully: **23/23** cases, `completed:true`, exact clean source `97a6c836e6180b2e61f1242560977ee21995258d`, smoke SHA-256 `a48aada8f9b1b1173f9be73c3a2715b9bf3932246bc7457bcc1296f65abddba8`. Local environment: Python 3.9.6 and QEMU 11.1.1. The command builds and boots the three actual variants privately; it does not rebuild the checkout's shared userland image or targets. + +Checked all raw fixture/probe traces and output diagnostics against recorded JSON independently of its pass summary. Actual variants show: + +| Private variant | Greeting / exit / completion | Smoke exit and diagnostic | Unrelated listed fault | +|---|---|---|---| +| Omit EL0 publication | absent / absent / present | 1; missing userspace-exit marker | None | +| Omit completion | present / present / absent | 1; missing completion marker | None | +| Release greeting | present / present / present | 1; forbidden release greeting | None | + +Fault patterns remain synthetic trace injection; these are not actual CPU-fault kernels. The actual release-greeting variant injects public serial text at the completion site to test the consumer, not an adversarial syscall image or changed release syscall implementation. + +**Own refusal and partial-failure controls:** invoking the harness with the existing completed evidence directory exits 2 and preserves every file's SHA-256. In a disposable script copy, forcing the actual smoke gate to reject its first positive fixture makes the harness exit 1, saves the failed case with all three markers present, retains raw/output evidence and `completed:false`, and cleans scratch. This excludes a harness that reports overall success merely because something failed. Evidence: `/tmp/tyrne-b21-t034-round2-code-integrity.json` and `/tmp/tyrne-b21-t034-round2-code-failed-probe-v2/`. The experiment uses read-only Git metadata with a private work tree and optional Git locks disabled; its dirty flag is intentionally true. No repository source is mutated. + +The shared debug hello.bin is still 117 bytes with SHA-256 `05816ccb9be5caea862dbe3e0fc45fc2068ff06cd049f2dda3459492d0ef7d88`, matching supplied earlier baseline. This reviewer did not take its own before snapshot for the actual harness, so does not represent that comparison as an independent before/after proof; isolation was inspected, and the paired security reviewer independently captured and compared shared image and debug/release ELF hashes before/after its own run. + +**Supplied corrected hosted proof, independently inspected:** [run 38183696397](https://github.com/HodeTech/Tyrne/actions/runs/38183696397) metadata binds source `97a6c83` and records all six jobs success, including the inherited guard, both production guest steps, direct probes and artifact upload. Downloaded `/tmp/tyrne-b21-step6/corrected-hosted-artifact/` has correct raw debug/release marker shapes, no listed fault, actual missing-EL0 guard output, completed clean-source 23-case probe JSON with matching smoke hash and actual raw probe shapes/diagnostics. The full hosted log records the corrected effective shell for guard and both production pipelines. + +The production raw trace SHA-256 values computed here are debug `b5810d4ed20e5e011a80efb4bd53cde47d61f1030f23087117304c3270c2f788` and release `b1e8a492601e120c13dd7a0f658b4745e7be7797ab87a9a5b1cbe672037c6912`. A complete extracted-file hash manifest is `/tmp/tyrne-b21-t034-round2-code-artifact-hashes.json` (53 own harness files; 62 corrected hosted evidence files). This is content integrity evidence, not artifact service authentication. + +Hosted metadata records QEMU 8.2.2 (Debian 1:8.2.2+ds-0ubuntu1.18), pinned rustc 1.94.0-nightly, x86_64 Linux, attempt 1 and initialized evidence interval 100 s. Job timestamps independently yield 108 s full job duration. Parent reports artifact ID 11719065723, size 24,093 bytes and service digest `616c7c4828650dcefc8ab3c7d3d5990f999e8f6df3d0c908665a37c12d355da0`; those archive/service values were supplied, not independently recomputed from the original archive. + +No missing test blocks this scoped change. Exact SVC counting, hostile EL0 images, genuine CPU-fault injection, SMP/hardware behavior and existing assembly defects are outside the declared contract. No deliberately broken hosted source commit or red production workflow was created. Local broken-shell sensitivity plus the hosted inherited guard and effective shell establish failure propagation. Prior broad suites and corrected hosted job conclusions are supplied evidence; this pass did not rerun broad host tests, Miri or unrelated lint suites without a concern. + +### Documentation + +**Clean.** Task, guides and standards now state matching debug/release builds, exact required/forbidden markers, explicit-ELF profile selection, watchdog trace verdict, Python prerequisites, 20 synthetic versus three real cases, isolated mutations, artifact refusal/provenance and 14-day retention. Pipeline-fix documentation explains inherited Bash and the regression guard. No architecture, public Rust API, unsafe safety section or audit entry needs an update for this host-only delta; ADR-0040 governs the process/runtime-assurance choice. + +Evidence-only `9092581` records corrected hosted proof without overwriting historical Round 1 Requests changes, and leaves fresh-round/live-policy/final-PR work pending. A focused post-fix sweep of changed live guide/standard/workflow files found none of the obsolete no-QEMU-job, four-real-gates or pending-hosted-release wording. Task/current/index remain In Review. The workflow header describes the intended merge-gate arrangement; the task's unchecked live-registration item and roadmap explicitly identify that setting as pending, so this review does not certify it as already installed. + +Commit subjects are conventional and `Refs: ADR-0040` identifies the accepted authority. The fix commit records historical code/security Requests changes truthfully. Review publication and final trailers belong to the coordinator; no nonexistent final PR number or Done claim is introduced. The complete scoped delta is cohesive assurance, tests, evidence and documentation, with no unrelated production refactor; the final stacked PR remains subject to its own description/size and maintainer review. + +### Integration + +**Clean for the approved development step.** New `qemu-smoke` has exact display name `QEMU debug + release smoke (nightly)`, Ubuntu runner, ten-minute job limit, pinned checkout/cache/upload actions, unchanged `contents: read`, no new secret and no persisted checkout credentials. Matching debug image/kernel are built and booted before matching release image/kernel. Cache namespace is separate from other jobs. Probe builds use tracked-source copies and private target/image paths; no ignored shared image or target is copied into the private source. + +Evidence initialization through GITHUB_ENV precedes relevant failure paths; production raw logs and combined tee output have dedicated profile paths, avoiding overwrite. Always-run wall-time/upload steps retain evidence available on ordinary failure and fail on missing files. Job cancellation, runner loss and hard timeout may prevent cleanup or upload; neither source nor this review promises otherwise. The outer job bound covers subprocess build hangs; the standalone harness does not have a separate Cargo wall-time limit. + +No Cargo dependency, Rust lockfile/toolchain, kernel-linked code, ABI, capability grant, HAL boundary or production scheduler change. Python is stdlib-only; QEMU and the artifact action are host execution dependencies. Rolling Ubuntu/QEMU packages are version-recorded, not claimed bit-for-bit pinned. Diagnostic artifacts select the dedicated evidence directory, not home/environment/credential stores. No live protection or admin operation occurs in CI. + +`git diff --check 07449f1..9092581` passes and tracked worktree is clean at review completion. Existing HIGH T-038 remains excluded, unchanged and undowngraded; successful guests are not an approval of the input-only x2 asm contract. No new unsafe approval is applicable. The full distinct security report's eight-axis verdict and limitations agree with this review; no unreconciled blocker remains. + +### Full code-review checklist + +| Item | Outcome and justification | +|---|---| +| Correctness | **OK:** profile markers/faults and actual pipeline rejection verified; R1 HIGH fixed. | +| Capability semantics | **N/A to runtime delta:** no capability check, grant, transfer or syscall implementation changes; token permissions stay read-only. | +| Fault containment | **OK for delta:** host gate rejects listed faults and missing behavior; no runtime fault handling changed. | +| Unsafe discipline | **N/A:** no shipped unsafe, assembly or safety-argument modification; T-038 HIGH is retained, not certified. | +| Error handling | **OK:** build/subprocess/probe failure cannot qualify as overall success; partial evidence survives; pipefail preserves production rejection.

Canonical check ordering does not erase a binding or alter semantics. Duplicate JSON keys are rejected rather than taking the last value. +- `live` examines repository/inherited rulesets, the applied classic rule and full REST protection. Unsupported GraphQL actor/deployment policies are rejected by exact supported-baseline comparison. Unknown REST policy is not silently omitted. Known URL/context metadata is the only normalized response metadata. +- `apply` has explicit local invocation, CI-environment refusal, expected full-baseline equality, additive-only context preservation including strict/app bindings, full lowercase SHA proof, exactly one completed successful app-bound remote check per addition, a second full read immediately before the narrow status-checks PATCH and a full post-write read-back.

The narrow update path and source-app identity requirement agree with the API contract. + +## Integration + +### R1-CODE-01 — Medium, blocking: inherited ARM negative probe accepts only one legitimate diagnostic + +- **Location:** `tools/test-ci-gates.sh:61–74`, especially line 74, as present at immutable e873995. This file is inherited from T-036 and is **outside the 15-file T-035 diff**. +- **Observed evidence:** `/tmp/tyrne-b21-step7/registration-tip-failure.log`, hosted run **38186028266**, source **69ac515**. The isolated hello arch-only mutation invokes exact workspace clippy `--all-targets`, and Cargo reports `error: unwinding panics are not supported without std`, then `could not compile tyrne-userland-hello (bin "hello")`. The rejection harness nevertheless fails because it requires only `error[E0152]: found duplicate lang item panic_impl`. +- **Why it is a defect:** The mutation makes both the normal hello binary and its test variant ill-formed on the ARM host. Parallel target compilation can expose the normal no_std/unwind failure before the duplicate panic_impl test failure. The negative assertion therefore turns a legitimate rejection of the intended regression into an intermittent red **required** check. Earlier and exact-tip green runs demonstrate intermittence, not safety of the single-diagnostic assumption. +- **Required correction:** Keep the exact mandatory workspace gate and isolated mutation. Deterministically prove the intended regression, or narrowly recognize both legitimate diagnostic classes with target/source context and controls that reject unrelated errors and unexpected success. Preserve the historical failed run and distinguish a failed command inside an expected-failure probe from an actual red workflow. Re-run local/hosted controls and both fresh round-2 reviewers on the entire correction/cross-step delta. +- **Status:** Parent independently found and verified this issue before receiving this report and is correcting it. This review independently read the failure evidence and source. It is not a new T-035 security vulnerability or reason to downgrade/exclude the existing separate HIGH T-038 asm issue. + +No new Cargo/Python package dependency, API rename, syscall/kernel behavior, binary blob or CI administrative credential is introduced. New offline fixtures are included in the existing required fast lane. The performance job remains deliberately outside required checks. Actual policy application is confined to a local narrow endpoint; real T-035 application was a no-op because the six reviewed checks were registered in preceding steps. + +### Full code-review checklist + +| Standard item | Disposition | +|---|---| +| Correctness | T-035 clean; inherited required-check flake R1-CODE-01 blocks integrated readiness | +| Capability semantics | No OS capability change.

There is **no additional confirmed finding in the new T-035 code**. The exact-tip hosted performance artifact and seven green CI jobs are verified; they do not erase the separately observed flaky required check. Parent must apply the localized correction, record hosted evidence and submit the full corrected delta to the two fresh round-2 reviewers.

The independent security pass approves only the scoped T-035 security delta at the same exact e873995 SHA, with no new actionable security finding; it explicitly corroborates and retains the inherited T-036 integration hold. Its eight axes, 33 checklist dispositions, P1–P12, 72 additional explicit normal/optimized adversarial controls, secret-failure/timeout controls and hosted artifact analysis were read and assessed. The security result agrees with this code review: no new T-035 defect, non-atomic admin races honestly limited, existing HIGH T-038 unchanged/excluded/undowngraded, and correction plus fresh round 2 still required. The security approval is not an overall integration or maintainer approval. + +## Round2 — code + +# Code review 2026-10-12 — T-035 Step 8 and late T-036 correction, fresh Round 2 + +- **Change:** full immutable combined delta `69ac515393f8f20ff0a11587a309182388bcde51..7deb16eae6274d48391c6c6525515a4e8bbdd66f`, `development`; 23 files, 1643 insertions, 54 deletions.

Immutable `git archive 7deb16e` under `/tmp/tyrne-b21-round2-code-private`. Only local fake services/temp files were mutated.

Truncated prerequisite output was recovered in bounded reads. Read both complete canonical T-035 Round 1 reports, T-035/T-036 tasks and the late T-036 reconciliation before reviewing. Description and tests preceded implementation; then definition/schema/normalization, transport/reconciliation, shell/harness and workflow callers were traced in dependency order. All five roles, the entire standard checklist and P1–P12 are disposed below. + +## Correctness + +**No new confirmed actionable finding in the full combined delta.** The inherited Medium R1-CODE-01 is corrected by the reviewed change and independently verified. + +### Administrative definition and tool + +- `.github/branch-protection/main.json` preserves the six existing exact context/app pairs (all app15368), strict checking, nine REST toggles, review settings/count, null restrictions, GraphQL-only applied-rule review/deployment/restriction/actor baseline and empty rulesets. It equals the parent-captured `/tmp/tyrne-b21-step8/live-export.json` byte-semantically after JSON parsing. +- `tools/branch-protection.py:57–146` validates exact required fields and types, duplicate object keys/contexts, positive explicit app IDs and supported representation. Unknown fields, bool/int confusion and unsupported actor/deployment/restriction extensions fail closed. Sorting contexts preserves bindings. Known response URL/duplicated contexts metadata is normalized without dropping unknown policy. +- `tools/branch-protection.py:154–176` fixes hostname, repository, branch and API endpoints. `gh` receives argv, explicit methods, timeout and stdin JSON; there is no shell interpolation or token in argv. The GraphQL POST is a constant read-only query. Errors do not echo `gh` stderr or captured timeout stderr. +- `tools/branch-protection.py:179–225` preserves every old context/app pair and all non-status/strict policy. Additions require full lowercase SHA and exactly one completed successful check at that SHA from the explicit app. Truncated/duplicate evidence is refused. Complete REST/GraphQL/ruleset comparison occurs before proof, immediately before the narrow status-check PATCH and after a write. Matching desired policy performs two full reads and zero writes. +- Explicit `apply` refuses CI markers even when their values are `false`. Production guards use exceptions, not optimization-sensitive assertions. No CI job obtains administration credentials or runs live reconciliation. +- The operation has no atomic compare-and-swap. Concurrent administration after the final read can still race; the guide accurately records the limitation, requires coordination and avoids automatic rollback. No atomicity guarantee is inferred from the successful controls. + +### Performance reporting + +- `.github/workflows/performance.yml` implements Monday03:17UTC, dispatch and development pushes limited to the workflow/harness paths, with no PR trigger. It is separate and informational, has contents-read permissions, nonpersistent checkout credentials, immutable action pins, architecture-separated performance cache and ten-minute outer timeout. +- Matching debug userland precedes debug kernel build. Explicit Bash preserves a fatal harness status through `tee`; one fixed-form report path is required before copying. Always-run wall metadata and artifact upload preserve available diagnostics with 14-day retention. Runner loss/cancellation can still prevent delivery; this is not guaranteed archival. +- `tools/perf-harness.sh` changes only source/tool provenance: full SHA, tracked worktree state, active compiler/toolchain in summary/report. Missing Git status becomes unknown rather than clean. Existing sampling/watchdog/statistics/failure-threshold/append-only behavior remains unchanged. +- A partial set meeting the existing ceil(n/2) threshold is reported with explicit valid/failed counts; it is not a performance-regression threshold. Exact workflow controls demonstrated 20/20 and 19/20 report success, zero-sample failure with retained output and rejection of an unexpected report path. + +### R1-CODE-01 resolution + +`tools/test-ci-gates.sh:52–74` now requires the ARM command to return compiler exit101 and a full-line match to either observed class: duplicate `panic_impl` or unsupported no_std unwinding. It prints the class actually matched. The exact workspace all-targets clippy command, all six hello cfg mutations, unchanged build script/shim, private Cargo target and host/anchor guards are preserved. + +The two failure classes arise from the same isolated cfg regression, with Cargo able to report normal binary or test-target failure first. An unrelated exit101, a near-match diagnostic, wrong status even with a recognized diagnostic, or command success is rejected. Recognition is deliberately narrow rather than any nonzero-exit acceptance. + +Independent proof: + +1. Nine permanent offline methods pass normally and under Python `-O`, including both classes and refusal/isolation/cleanup contracts. +2. A private control replaces only the copied shell with immutable base69ac515 bytes: the unwind fixture fails the old single-class assertion and passes corrected7deb bytes. +3. An actual native Apple ARM run of immutable7deb shell/source, with only immutable Git file enumeration supplied privately and actual installed rustc/Cargo, returns harness0 after compiler101/E0152. Temporary source was not changed and scratch was empty afterward. +4. Corrected hosted [run38187736985 / ARMjob114613632255](https://github.com/HodeTech/Tyrne/actions/runs/38187736985/job/114613632255) at7deb actually returns the **other** exact class, `error: unwinding panics are not supported without std`, and the assertion passes. This directly covers the previously observed hosted failure class. Positive workspace clippy precedes the private mutation; native tests and Miri follow and pass. + +## Style + +Clean. English source/comments/docs and conventional commits with ADR-0040 references. Ordinary Python stdlib and portable Bash; no new package dependency, Rust/unsafe or diagram. Independently executed actionlint on both immutable workflows and ShellCheck over all immutable shell scripts pass; repository immutable-range `git diff --check` passes. + +This is a large authorized Step8, predominantly the two ADR-0040 interfaces, fixtures, retained reports and review history.

Every prewrite rejection asserts zero fake mutations; postwrite divergence asserts one write and no rollback. Private scripts use unittest assertions and explicit exceptions and remain meaningful under `-O`. + +No missing blocking test was identified for this delta. No changed guest runtime warrants repeating every kernel test locally; the new host interfaces have direct synthetic/negative tests, the actual ARM command was repeated, and corrected exact-source hosted CI/runtime artifacts were inspected independently.

Downloaded report/log/metadata/tool versions agree on clean source, pinned Rust, QEMU8.2.2/Linuxx86_64,20requested/20valid/0failed, harness101s/evidence139s.

Recomputed raw nearest-rank p10/p50/p90 =8,408,784/9,120,416/12,621,792ns; mean/stddev also agree. +- Retained `perf-baseline-2026-10-12-t035-hosted-check.md` is exactly equal to downloaded report bytes. The harness and performance workflow are byte-identical at e873995 and7deb; no extra performance trigger is expected for the correction's untouched performance paths. This is source-bound e873995 measurement evidence of unchanged performance code, not a claim that performance ran at7deb. +- The committed local report is correctly labeled dirty tracked base69ac515, QEMU11.1.1/Apple ARM,20valid/0failed,harness100s.

This reviewer did not invoke live export/apply or certify a live mutation. Mutating behavior was exercised exclusively against local fakes. +- Artifact service IDs/digests remain attributed service metadata.

Public commands/statuses, app binding, complete supported policy/refusal, full readback, no-op, administrative race, schedule default-branch/best-effort/inactivity semantics, re-enable/dispatch/download and retention are documented. Coverage's old post-T011/neutral-result claims are corrected without inventing an enforcing floor. + +Both full canonical Round1 reports preserve their source-bound verdicts and integration finding. Late T036 reconciliation records the failed hosted run and correction instead of rewriting prior green evidence. Current/task text saying corrected hosted proof/R2 pending was accurate at7deb commit time; parent will reconcile completed evidence after this fresh round. No finding is raised for that honest immutable snapshot. + +Manual dispatch/default-branch scheduling and first merged-main proof are correctly deferred until maintainer merge.

Bounded follow-up reads recovered truncated output. ADR-0040 is Accepted and authorizes the eight-step Track B.2-1 sequence; step 7 is within that authorization. No repository edit, commit, branch operation or live settings write was performed by this reviewer. The requested temporary report is supplied to the coordinating agent for canonical filing/indexing. + +## Correctness + +- **Clean; no correctness blocker.** `.github/workflows/ci.yml:275–320` runs on `ubuntu-24.04-arm`, has a 15-minute timeout and explicit Bash, installs pinned nightly clippy and Miri, selects the same nightly by override, and verifies both actual `uname -m == aarch64` and `rustc` host `aarch64-unknown-linux-gnu`. No target override turns these into cross-compiles. Native compilation, linking/execution, and interpretation are separate mandatory steps; neither the probe nor Miri replaces positive native tests. +- **Exact four commands verified:** + + ```sh + cargo +"$NIGHTLY_PIN" check --workspace --exclude tyrne-bsp-qemu-virt + cargo +"$NIGHTLY_PIN" clippy --workspace --exclude tyrne-bsp-qemu-virt --all-targets -- -D warnings + cargo +"$NIGHTLY_PIN" test --workspace --exclude tyrne-bsp-qemu-virt + cargo +"$NIGHTLY_PIN" miri test --workspace --exclude tyrne-bsp-qemu-virt + ``` + + The pinned toolchain is `nightly-2026-01-15`; `cargo +"$NIGHTLY_PIN" miri setup` precedes interpretation. Only the bare-metal BSP is excluded. Both host-gated userland crates remain members of these workspace commands, unlike the existing default-members aliases. +- **Native versus guest boundary verified.** `.cargo/config.toml` has target-scoped bare-metal configuration, not a default bare-metal target. The six hello cfg predicates require both aarch64 and `target_os = "none"`; hello's build script applies `hello.ld` only to that bare-metal combination. Native ARM therefore builds the host stub and host-side crate contracts. This catches the original architecture-only cfg mistake, while proving no EL0 SVC, MMIO, bare-metal linker, device or multi-core behavior. Existing cross-build and QEMU jobs remain responsible for their own boundaries. +- **Probe semantics verified.** `tools/test-ci-gates.sh:21–80` refuses a non-aarch64 Rust host before creating a temporary copy; exactly six expected hello predicates must be present. It changes those predicates only in the copied main.rs, leaving the copied build script/syscall shim untouched. It invokes the exact native workspace clippy command with `--all-targets -- -D warnings`, requiring nonzero status and the specific ``error[E0152]: found duplicate lang item `panic_impl` `` diagnostic. Unexpected success and unrelated failure both fail the harness. A successful probe asserts compiler rejection; it is not a production compiler failure or a reproduced production Miri failure. +- **Isolation verified.** `mktemp -d`, quoted paths, NUL-delimited tracked paths, preserved script modes, private `CARGO_TARGET_DIR`, and EXIT cleanup confine modifications/build outputs to the temporary tree. The implementation copies the current tracked worktree, deliberately not an arbitrary historical commit. Review controls used an immutable archive with private git enumeration, so the reviewed source remained exact. No shared userland image was built or replaced. Comparing all 393 regular archived files against `git archive bf20ec9` after controls and the real probe found zero changed bytes; the real-probe temporary parent was empty afterward. + +## Style + +- **Clean.** The new job follows existing SHA-pinned checkout/cache and explicit toolchain conventions. Names describe the native host scope; shell quoting, argument validation, failure propagation and narrowly justified ShellCheck suppression are appropriate. No new Rust public API, `unsafe`, error enum or audit-log entry is introduced. +- Independently ran `actionlint .github/workflows/ci.yml`, `shellcheck tools/*.sh`, and `bash -n tools/test-ci-gates.sh` on the archived reviewed SHA: all passed. `git diff --check 9c5191c bf20ec9` passed. No style preference is promoted into a finding. +- The implementation commit is English, scoped to one logical CI change, and carries the valid `Refs: ADR-0040` trailer. + +## Test coverage + +**Present and meaningful:** + +| Evidence | Result | What it establishes | +|---|---|---| +| Hosted real Linux ARM job [114605118899](https://github.com/HodeTech/Tyrne/actions/runs/38184932784/job/114605118899), source bf20ec9 | All four positive commands and regression probe passed | Actual native Linux ARM execution, not emulation or a stub | +| Hosted native tests | 46 HAL + 259 kernel + 58 test-HAL + 3 doctests = 366 passed; two HAL doctests ignored | Host suite ran; userland host harnesses also built and ran with zero tests | +| Hosted Miri setup and tests | aarch64-unknown-linux-gnu sysroot prepared; same 366 passed, two ignored | Pinned native-target Miri execution; no UB diagnostic in exercised paths | +| Hosted negative probe | Actual clippy exited 101 with E0152 duplicate panic_impl; harness returned success | Deliberate copied cfg regression is rejected by the intended command | +| Independent real Apple Silicon probe | Real pinned rustc/Cargo; actual rejection 101/E0152; harness success | Reviewer independently reproduced compiler rejection using private source and Cargo home/target | +| Six independent controlled cases | All expected statuses, no source mutation, cleanup passed | Harness sensitivity, architecture guard, anchor guard and quoting/isolation | +| Independent syntax/lint checks | actionlint, ShellCheck, Bash syntax and diff whitespace passed | Workflow/shell validity at immutable source | + +The hosted log at `/tmp/tyrne-b21-step7/hosted-arm.log` was inspected directly: checkout fetch/log identifies full SHA `bf20ec9739db635183b1b930f4da9f2c2b6813bf` (lines 93–106), installed rustc is `1.94.0-nightly (86a49fd71 2026-01-14)`, the real machine and Rust host are verified (lines 140–148), and positive/native/Miri results and expected rejection are present. Parent-fetched API timing records the full ARM job as 101 seconds, with Miri setup 17 seconds and interpretation 54 seconds; API times have second granularity. The full seven-job run subsequently completed successfully according to the coordinating agent; this reviewer independently inspected the ARM job log, not all other job logs. + +Independent control evidence is `/tmp/tyrne-t036-r1-code/independent-controls.json`, with fixtures/script under the same private directory. Cases were: expected duplicate-panic rejection on reported Darwin ARM; expected rejection on reported Linux ARM; unrelated compiler failure; unexpectedly green compiler; x86 host refusal; and a drifted sixth-predicate anchor. All six controlled cases use **stub rustc/Cargo** (the refusal/anchor guards prevent Cargo from being called), including the nominal Linux case: they prove harness behavior only. They are not presented as real ARM compiler evidence. Commands/PWD/private target were recorded and paths contained spaces. The separate real Apple Silicon probe used actual tools with only git tracked-file enumeration supplied for the archive. The coordinating agent's ten-case fixture set additionally covers CLI help/argument errors; it is supplemental, not the basis of the real compilation claim. + +**Missing:** no additional in-scope test is required for this CI-only change. Final-PR ARM green and first post-merge main-run evidence necessarily remain pending. Two ignored HAL doctests and existing Miri optimization/provenance warnings predate this diff; successful Miri proves the exercised host tests, not universal memory safety or hardware behavior. T-038's known x2-clobber work is separate scope and is not reopened here. + +## Documentation + +**One Low, non-blocking finding:** + +- **CODE-T036-R1-01 — Qualify pending live ARM required-check registration.** At immutable source `bf20ec9`, `docs/standards/testing.md:111` adds the ARM gate beneath line 102's heading **“Enforced in CI today (block merge)”**, without qualification. At that same SHA, the workflow header, CI guide, infrastructure standard and T-036 acceptance criteria explicitly say live registration follows hosted green and both fresh review rounds. A workflow job exists and fails correctly, but that does not itself make its display name a branch-protection requirement. A reader relying on the testing standard could infer that this gate already prevents merging. Add the same workflow-enabled/live-registration-pending qualification to this bullet, or place it in a clearly pending-registration subsection. Validation: inspect the resulting prose against the five currently registered checks, and retain pending status until live read-back exists. The coordinating agent independently confirmed this wording issue and is preparing the fix; that subsequent fix is outside this immutable review. + +Other documentation is appropriate: job table, exact native commands, Miri setup, host versus guest meaning, rejected-regression meaning, runner/timeout, all-cache architecture isolation, exact display name and pending live registration are recorded. T-036, index and current.md correctly retain `In Review`; they do not claim the final PR or post-merge run exists. Hosted timing was honestly pending when the implementation was committed and can now be appended using the actual source-bound run. ADR-0040 contains the governing decisions before the standards update; no unapproved policy change is being smuggled through a guide. + +The pre-existing coverage neutral/post-T-011 wording correction is expressly reserved for the immediately next T-035 step and is not a new T-036 finding. Existing unrelated doctrine cleanup is likewise not expanded into this change. + +## Integration + +- **Clean; no integration blocker.** Existing x86 host/stable/Miri/coverage, cross-kernel and QEMU smoke jobs retain their behavior; changes to their caches add architecture identity. Every exact key **and** every restore prefix includes both `runner.os` and `runner.arch`; no broad fallback can restore a different architecture: + + | Job/cache namespace | Exact key line | Restore prefix line | Remaining identity | + |---|---:|---:|---| + | lint host / cargo | 99 | 101 | nightly pin; lock hash in exact key | + | kernel / cargo-aarch64 | 156 | 158 | nightly pin; lock hash | + | guest / qemu-smoke | 234 | 236 | nightly pin; lock hash | + | native ARM / arm64-host | 304 | 306 | nightly pin; lock hash | + | host stable / cargo-stable | 354 | 356 | stable namespace; lock hash | + | Miri / miri | 393 | 395 | nightly pin; lock hash | + | coverage / llvmcov | 444 | 446 | nightly pin; lock hash | + + Restore prefixes deliberately permit an older lockfile cache within the same OS/architecture/job/toolchain namespace. Stable remains a rolling toolchain namespace as before; this does not undermine architecture isolation. Native ARM targets are also separated by the arm64-host job namespace. +- Runner availability was checked against the primary [GitHub hosted-runner reference](https://docs.github.com/en/actions/reference/runners/github-hosted-runners): `ubuntu-24.04-arm` is a standard public-repository ARM64 runner. The successful source-bound hosted job independently resolves the practical runner/Miri support question for this repository and pin. No paid or self-hosted runner assumption is introduced. +- **CI security boundaries:** global `contents: read` is unchanged; checkout uses a full action SHA and `persist-credentials: false`; cache action is full-SHA pinned. The new job adds no secrets, writable token scopes, `pull_request_target`, untrusted interpolation into shell source, publishing step, privileged service or self-hosted runner. Pull requests execute repository code only within the existing disposable hosted-runner model. Cache contents are build inputs/performance state, not a claimed trust or authenticity boundary. Job failure is not advisory and no `continue-on-error` weakens the ARM commands/probe. Explicit Bash preserves host verification pipeline failures. Live branch protection is deliberately a later, separately read-back action. +- No new dependency, lockfile, binary blob, public API, production behavior or unsafe audit obligation is introduced. T-037's accepted target-gating fix is a real prerequisite already present in the baseline; this change adds independent detection rather than altering it. + +**Architectural-principles pass:** + +| Principle | Review result | +|---|---| +| P1 no ambient authority | No runtime authority change; CI token remains read-only. | +| P2 smallest TCB | No shipped kernel/TCB growth; tooling stays in CI. | +| P3 userspace drivers/services | No subsystem relocation or device code added. | +| P4 boundary checks | No runtime trust entry changes; CI host/probe boundary checks fail closed. | +| P5 Rust-only kernel | No kernel-language or assembly change; shell/Python are build tooling. | +| P6 HAL separation | BSP excluded from host commands; hardware execution remains separate. | +| P7 no proprietary blobs | No blob or shipped binary addition; existing open toolchain/runner use only. | +| P8 ADRs | Accepted ADR-0040 governs runner, commands, trigger and mandatory Miri. | +| P9 repository English | Changed source/docs/commit are English. | +| P10 Mermaid diagrams | No diagram added. | +| P11 reproducibility | Exact nightly/action pins retained, lock identity retained, all cache fallback boundaries isolate architecture. | +| P12 complete scope | CI implementation complete to step-7 scope; review/live/final-PR/post-merge obligations remain explicit rather than prematurely Done. | + +## Verdict + +**Approve** + +All five role passes are complete. There are **zero Critical, High or Medium findings; one Low documentation finding**, CODE-T036-R1-01, is non-blocking under the master-plan approval semantics. No functional blocker was found. This recommendation applies only to immutable implementation `bf20ec9739db635183b1b930f4da9f2c2b6813bf` and does not approve unreviewed follow-up changes. + +The requested fresh second round must review the actual post-fix SHA independently. Live ARM required-check registration/read-back, final maintainer PR review/green and first merged-main run remain distinct pending obligations. Keep the task `In Review` until the authorized process reaches those stages; this code review is not a Done-promotion or live-settings authorization artifact. + +## Round 1 — independent integration + +# Code review 2026-10-12 — T-036 Step 7 Round 1, independent CI integration/test/documentation + +- **Change:** immutable `9c5191cfb8ced7e99e1afe459bb02852fde1a14b..bf20ec9739db635183b1b930f4da9f2c2b6813bf` on `development`; subject `ci: require native ARM64 workspace checks and Miri`. +- **Reviewer:** Codex independent reviewer `/root/b21_step7_round1_integration`; all five master-plan roles executed sequentially. This is a reviewer handoff, not a maintainer approval or a Done promotion. +- **Risk class:** Ordinary. This diff changes CI, a private rejection-test harness and documentation; no shipped Rust, assembly, capability, IPC, syscall, memory, scheduler, boot mechanism or unsafe boundary changes. +- **Security-review cross-reference:** n/a for this diff; CI supply-chain, permissions, credential handling and shell failure propagation were reviewed below. +- **Scope:** nine changed files, 133 insertions / 39 deletions. Source decisions and findings are anchored to `bf20ec9`, including while the parent prepares later documentation/evidence changes. No repository edits, branches, commits or live setting writes were performed by this reviewer. +- **Process inputs:** AGENTS.md, CLAUDE.md, current roadmap focus, numbered ADR corpus through Accepted ADR-0040, repository standards, `perform-code-review` and `conduct-review` skills, and full code-review master plan. Parent's explicit temporary-artifact-only scope defers canonical artifact/index/commit integration to the parent. + +## Correctness + +No blocking finding. + +- The new `arm64-host-check` job in `.github/workflows/ci.yml:274-319` uses explicit `ubuntu-24.04-arm`, pinned `NIGHTLY_PIN`, a 15-minute timeout and explicit Bash. Before checks it verifies both `uname -m = aarch64` and Rust `host: aarch64-unknown-linux-gnu`. This is a native host job, not a bare-metal cross-compilation substitute. GitHub's current official runner table identifies this image as Linux ARM64 with four CPUs; it is a standard public-repository runner. [GitHub-hosted runners reference](https://docs.github.com/en/actions/reference/runners/github-hosted-runners). +- All four required commands use `--workspace --exclude tyrne-bsp-qemu-virt` and no `--target`. Check, clippy with `--all-targets -- -D warnings`, native test, and Miri therefore include both `tyrne-user` and `tyrne-userland-hello`. The default-members-only aliases would omit those crates; the implementation correctly avoids them for this gate. The config has no global build target redirecting these commands to bare metal. +- Miri is installed for the pinned nightly and `cargo miri setup` precedes interpretation. Native linking/testing and Miri remain distinct checks. No global `RUSTFLAGS` or weakened diagnostics are introduced. +- `tools/test-ci-gates.sh --arm-host` checks the actual Rust host is `aarch64-*` before copying. It copies tracked source into a private `mktemp` tree, exports a private Cargo target directory, changes exactly six compound hello cfg predicates to arch-only, and leaves the wrapper/build scripts alone. A count different from six fails before cargo runs. Production sources and the existing shared target/image are not mutated. +- `run_negative` captures a nonzero command status explicitly, rejects an unexpectedly successful command, and also requires the exact fixed duplicate-`panic_impl` E0152 diagnostic. An unrelated compiler failure is refused. The intended clippy failure exits 101 while the successful rejection harness exits 0; those are different outcomes. The harness does not claim that this compile failure is a new Miri UB reproduction. +- Quoted paths, NUL-delimited tracked-file copying, `set -euo pipefail`, and EXIT cleanup preserve operation under system Bash 3.2 and paths containing spaces. Source-anchor drift and non-ARM hosts fail closed. A shell failure is not converted to a passing ARM gate. + +## Style + +Clean; no style finding. + +- Actionlint and ShellCheck both pass independently on the immutable archive. Existing pinned actions and shell conventions are reused. The narrowly scoped ShellCheck suppression protects a literal Rust diagnostic containing backticks. +- English repository text, a `ci:` commit subject and `Refs: ADR-0040` comply with the relevant conventions. No new Rust public API, error variant or unsafe region requires rustdoc, `# Errors`, `# Safety` or an audit entry. +- `git diff --check 9c5191c bf20ec9` passed. No cosmetic redesign is requested. + +## Test coverage + +The implemented gate has adequate positive and adversarial evidence. No missing blocking test was identified. + +**Independent real local execution.** Exact `bf20ec9` was exported with `git archive` into a private path containing a space; Cargo outputs were redirected to a private target directory. Host was Apple Silicon (`aarch64-apple-darwin`), pinned Rust `1.94.0-nightly (86a49fd71 2026-01-14)`.

Both userland crates appear in the runs even though their host test count is zero. Miri reports no UB; existing optimization/provenance warnings are not a new defect or a proof of complete soundness. Local setup reused the already-built Miri sysroot, so its short setup time is not evidence of a cold hosted setup. The actual local arch-only mutation produced E0152 and clippy exit 101; the harness returned 0. + +Local raw evidence: `/var/folders/d2/k7c1fj3976g7_qq7113f66p00000gn/T/tyrne-t036-integration-4xqks6sx/`, `command-0.log` through `command-7.log` and `results.json`. These are reviewer-local logs, not committed CI artifacts. + +**Independent mocked failure-path controls.** Using private copies of the same archive and stubbed `rustc`/`cargo`, ten cases passed under `/bin/bash`: intended rejection for Apple and Linux ARM hosts; unexpected green compiler refusal; unrelated compiler-error refusal; x86 refusal without cargo; five-anchor drift refusal without cargo; missing, surplus and unknown argument rejection; help success. The cargo stub additionally checked exact clippy argv, a private Cargo target, and complete cfg mutation. Cleanup and original private source preservation were checked. These validate harness branches and isolation; they are explicitly mocked, not native compiler or Linux execution evidence. Results are in `independent-mocked-controls.json` alongside the logs. Parent's ten-case fixture results at `/tmp/tyrne-b21-step7/fixture-results.json` provide corroborating evidence. + +**Hosted evidence received during this review.** I independently inspected the parent's ANSI-stripped `/tmp/tyrne-b21-step7/hosted-arm.log` for job `114605118899` in run `38184932784`. It records Linux `aarch64` / Rust `aarch64-unknown-linux-gnu`, all four workspace gates, both userland members, 366 passing tests plus two ignored doctests for native and Miri, and the expected E0152 clippy exit 101 / harness 0. Miri really builds the Linux ARM sysroot (about 17 seconds in the log). Parent-reported GitHub API timestamps give a 101-second complete job, native check/clippy/test approximately 1/1/4 seconds, rejection probe 7 seconds, setup 17 seconds and interpretation 54 seconds; API seconds are coarse, not benchmarks. [Hosted ARM job](https://github.com/HodeTech/Tyrne/actions/runs/38184932784/job/114605118899). + +The parent subsequently reported all seven jobs in the complete run green. I did not independently fetch the complete run API or rerun QEMU: hosted ARM conclusions above are based on the inspected job log; the complete-run result is parent-supplied evidence. The QEMU machinery is unchanged except architecture cache segregation and prior T-034 pipefail correction is retained. + +## Documentation + +**LOW — T036-R1-INTEGRATION-01: premature merge-blocking claim.** At immutable `bf20ec9`, `docs/standards/testing.md:111` places the new ARM gate under `Enforced in CI today (block merge)` at line 102. The task, guide, current focus and infrastructure standard correctly distinguish implemented CI from pending live required-check registration. A green development run alone does not make the check a live branch-protection requirement. A contributor can therefore read a stronger enforcement guarantee than currently exists. + +**Requested correction:** qualify this ARM bullet explicitly as implemented with live required-check registration pending, and remove that qualifier only once the live policy has been applied and verified. This is a minor documentation finding; the workflow's actual test behavior is correct. Parent independently confirmed the finding and is preparing the correction. This report does not treat an unreviewed later working-tree edit as part of `bf20ec9`. + +Other documentation passes: + +- Task, task index and current focus consistently place T-036 `In Review` as approved step 7 on `development`. T-037 and the preceding selected tasks may have completed both rounds while remaining In Review under Accepted ADR-0040's stacked-sequence exception. Nothing authorizes agent Done promotion. +- Guide and task describe the runner, native-versus-Miri distinction, exact commands, only-BSP exclusion, architecture cache isolation, private negative experiment, host requirement and historical E0152 failure accurately. +- At the commit boundary the source accurately records hosted timing/green evidence as pending. Hosted success arrived during review and can now be added as separately dated evidence. Required-check registration, both completed fresh review rounds, final maintainer PR review and first-main/post-merge evidence remain separate gates; no local or development result substitutes for them. +- Release requirements are prospective policy, not a claim that registration has already happened. No architecture document or new ADR is needed beyond the Accepted ADR-0040 implementation policy. +- Unchanged coverage-neutral/post-T-011 prose belongs to explicitly next T-035. Known T-038 syscall clobber work is outside this diff and is not cleared by the host/Miri results. + +## Integration + +No integration blocker. + +**CI/security review.** Workflow permissions remain `contents: read`; all seven checkouts use the existing SHA-pinned action and `persist-credentials: false`. No administrative token, secret-bearing permission, `pull_request_target`, live policy mutation or new third-party action is added. The job uses GitHub's explicit Bash shell, whose normal runner invocation enables errexit and pipefail, and the negative harness handles its sole intended failure explicitly. No `continue-on-error` weakens ARM results. The 15-minute limit bounds an accidental hang; observed hosted runtime fits with substantial headroom. + +**Every cache key and fallback:** inspected all seven `actions/cache` uses, not only the new job. The cargo host, cargo-aarch64/kernel, qemu-smoke, arm64-host, stable, miri and llvmcov namespaces each include `${{ runner.os }}-${{ runner.arch }}` in both the exact key and every restore prefix. There are 14 key/prefix lines with architecture segregation. Linux x86 and Linux ARM therefore cannot restore one another's target cache through a broad fallback. Dedicated job namespaces remain distinct. Toolchain pin/lock portions remain in the existing key structure. The negative probe never uses the shared target cache. + +**Dependencies and downstream behavior:** no Cargo manifest/lockfile or shipped Rust changes; no new dependency needing add-dependency procedure. Host and cross-target jobs retain their responsibilities. Both userland members stay in the ARM workspace checks while only the inherently bare-metal BSP is excluded. Existing smoke, release, stable, coverage and x86 Miri jobs remain present. No symbol or ABI changes exist. + +**Architectural principles P1–P12:** + +| Principle | Disposition and evidence | +|---|---| +| P1 No ambient authority | Pass: no shipped privilege path changes; CI token remains read-only. | +| P2 Smallest defensible TCB | Pass: no kernel/TCB growth; bounded host-side gate only. | +| P3 Userspace placement/fault containment | Unchanged: no driver/service placement or fault boundary change. | +| P4 Capability checks | Unchanged: no syscall, IPC or cross-task entry point changes. | +| P5 Rust-only kernel | Pass: shipped Rust/assembly unchanged; Bash/Python are host test orchestration. | +| P6 HAL separation | Unchanged: no CPU detail enters kernel code; host architecture check stays in CI. | +| P7 No proprietary blobs | Pass: none added, linked, embedded or required. | +| P8 ADR governance | Pass: required ARM/Miri policy, sequencing and registration timing follow Accepted ADR-0040; commit references it. | +| P9 English repository | Pass: changed artifacts and commit are English. | +| P10 Mermaid diagrams | N/a: no diagrams added or changed. | +| P11 Reproducibility | Pass within scope: pinned nightly/actions retained; architecture-segregated exact and fallback caches; no lock/dependency change. | +| P12 Complete declared scope | Pass for implementation review: all required commands and rejection gate exist; external registration/review/merge evidence remains explicitly pending, not silently certified. | + +**Standard checklist:** correctness/pass; capability semantics/unchanged; fault containment/unchanged; unsafe annotations/audit/no unsafe change; error handling/pass through fail-closed controls; tests/pass with real and mocked evidence clearly separated; documentation/one Low above; architecture/P1–P12 covered; dependencies/no additions; style/pass; commit format/pass. Canonical review artifact/index insertion is the parent's integration step under the explicit no-repository-writes review assignment. + +## Verdict + +**Approve** — one Low, non-blocking documentation correction (`T036-R1-INTEGRATION-01`); zero blocking runtime, harness, cache or CI-security findings. + +This verdict concerns only the immutable Step 7 implementation. Correct the enforcement wording before the next review round, preserve the hosted evidence boundary, and complete the separately required second fresh round/live registration/final maintainer review/post-merge evidence. It does not promote T-036 to Done, approve a live-policy write, certify a first main run, or resolve T-038. + +## Coordinator verification and correction + +CODE-T036-R1-01 and T036-R1-INTEGRATION-01 describe the same Low finding.

The pin agrees with `rust-toolchain.toml`: `nightly-2026-01-15`. Miri setup precedes interpretation. + +The exact four mandatory commands are present and non-advisory: + +```sh +cargo +"$NIGHTLY_PIN" check --workspace --exclude tyrne-bsp-qemu-virt +cargo +"$NIGHTLY_PIN" clippy --workspace --exclude tyrne-bsp-qemu-virt --all-targets -- -D warnings +cargo +"$NIGHTLY_PIN" test --workspace --exclude tyrne-bsp-qemu-virt +cargo +"$NIGHTLY_PIN" miri test --workspace --exclude tyrne-bsp-qemu-virt +``` + +Only the BSP is excluded. Explicit `--workspace` includes both userland members despite the workspace default-members excluding them. There is no default bare-metal target or global RUSTFLAGS; bare-metal codegen settings remain target-scoped. Native compile/link/test and Miri interpretation are distinct mandatory evidence. Hello's six predicates and its build script keep bare-metal entry/panic/linker behavior gated on both architecture and OS; native ARM exercises the host configuration, not EL0 SVC/MMIO or real hardware. + +`tools/test-ci-gates.sh:21` refuses a non-aarch64 Rust host before copying, then uses NUL-delimited tracked-file enumeration, quoted paths, `cp -p`, private mktemp source/target paths and EXIT cleanup. Its `--arm-host` arm requires exactly six expected hello predicates; it modifies only the copied `userland/hello/src/main.rs`, leaving the copied build script and syscall shim intact. It runs exactly `cargo clippy --workspace --exclude tyrne-bsp-qemu-virt --all-targets -- -D warnings`. Nonzero status alone is insufficient: the precise E0152 duplicate `panic_impl` diagnostic must also occur. Unexpected green and unrelated compiler failure reject the probe. The probe's zero status means deliberate compiler rejection was correctly asserted, not a new production Miri failure. + +Independent actual Apple ARM positive clippy and real negative compilation passed at the reviewed tip. Independent stub controls additionally verified all intended branches, unchanged private source and complete cleanup; evidence is detailed below. No shared Cargo target or userland image was modified. + +## Style + +**Clean; no finding.** Workflow conventions, full-SHA checkout/cache actions, explicit toolchain selection, readable job names and shell quoting are consistent with the existing pipeline. The literal-diagnostic ShellCheck suppression is narrow and justified. No new Rust API, error type, dependency or unsafe annotation obligation is introduced. + +Independently executed `actionlint .github/workflows/ci.yml`, `shellcheck tools/test-ci-gates.sh`, `bash -n tools/test-ci-gates.sh` on the immutable private archive and `git diff --check 9c5191c 5c95cd3`: all exit 0. The implementation and review-follow-up commits use English Conventional Commits and valid ADR references; the follow-up has the canonical Code-Review trailer. Canonical Round 2 artifact/index integration is the coordinator's remaining mechanical task, consistent with this no-repository-writes assignment. + +## Test coverage + +**Adequate for this ordinary CI-only scope; no missing in-scope test.** The independent controls concentrate on the changed gate and its failure modes rather than gratuitously repeating unchanged broad gates. + +### Newly executed real controls + +Exact `5c95cd3` was exported with `git archive` to a private path containing spaces. CARGO_HOME, positive Cargo targets and temporary probe parents were private.

No kernel image was built by these controls. Newly executed local tests/Miri are not claimed here: their full-suite evidence is independently inspected hosted evidence and the separately preserved Round 1 local results. + +### Newly executed controlled failure paths + +Six independent cases ran under system `/bin/bash` with stub rustc/Cargo, each in its own private source tree with spaces. Apple ARM and Linux ARM expected rejection returned 0; unexpected compiler success returned 1; unrelated compiler error returned 1; x86 Rust host returned 1 without calling Cargo; a five-predicate anchor drift returned 1 without calling Cargo. Each case verified original private-source preservation and empty temporary parent after exit. Cargo-called cases asserted exact argv, private target path, complete six-predicate mutation, and unchanged copied hello build script/syscall shim. + +These nominal Apple/Linux controlled cases prove harness behavior only. They are explicitly **stubs**, not independent real Linux/native/Miri executions. The separate actual Apple compiler execution above supplies real rejection evidence. + +Private raw evidence is at `/var/folders/d2/k7c1fj3976g7_qq7113f66p00000gn/T/tyrne-t036-r2-code-3xr0e127`: `real-results.json`, `host.log`, `positive-clippy.log`, `real-negative.log`, `controlled-results.json` and each case's output/command record. This is reviewer-local evidence, not a committed artifact or a hosted rerun. + +### Independently inspected hosted evidence + +The coordinator-fetched `/tmp/tyrne-b21-step7/hosted-run.json` records a completed successful run with **all seven jobs successful**, including the informational coverage job. `/tmp/tyrne-b21-step7/hosted-arm.log` directly binds checkout to full source SHA `bf20ec9739db635183b1b930f4da9f2c2b6813bf` at lines 92–106. This is the actual hosted source, not the later documentation-only reviewed tip. Independently checked `git diff bf20ec9 5c95cd3` shows no CI/tooling/runtime configuration change between those SHAs, so the hosted implementation evidence remains applicable while the Round 2 prose correction is assessed directly. + +The ARM log records real `aarch64` and `aarch64-unknown-linux-gnu` verification, pinned toolchain installation, all four exact workspace commands, E0152/exit101 negative rejection, actual Linux ARM Miri sysroot preparation, native/Miri execution of both userland host harnesses, and native/Miri totals of 46 HAL + 259 kernel + 58 test-HAL + 3 doctests = **366 passed**, with **two ignored HAL doctests**. No UB diagnostic is reported. API timestamps independently calculate ARM job **101 seconds**, Miri setup **17 seconds** and interpretation **54 seconds**; second-resolution times are diagnostic wall times, not performance benchmarks. Hosted link: https://github.com/HodeTech/Tyrne/actions/runs/38184932784/job/114605118899. + +I inspected these fetched JSON/log files; I did not fetch a new hosted run, execute Linux ARM locally or rerun QEMU. Other six jobs' success is verified in the run JSON, not by independently inspecting each job log. Existing Miri optimization/provenance warnings, ignored doctests and host/guest scope limitations remain accurately bounded. This does not certify universal memory soundness or the known separate T-038 x2-clobber issue. + +## Documentation + +**Clean; no new finding. Round 1 Low fixed.** The complete canonical Round 1 report preserves both original immutable-source reports and their evidence boundaries. At reviewed tip `5c95cd3`, `docs/standards/testing.md:111` now explicitly states that the workflow is enabled while live required-check registration awaits hosted green and both fresh review rounds. This qualifies the parent enforced-gates heading and resolves CODE-T036-R1-01 / T036-R1-INTEGRATION-01. The task, guide, infrastructure standard, workflow header and current/index pointers agree on pending live registration and remain `In Review`, not Done. + +The task correctly checks development-hosted success, records source-bound timings, and leaves final PR green, first merged-main verification and live ARM registration unchecked. The guide identifies exact display name, commands, host boundary, six-predicate copied regression and positive/native/Miri distinctions. The release standard describes prospective required release gates. ADR-0040 supplies Accepted authority for the policy before these standards edits. + +Changed Markdown local-link checking, excluding inline-code examples, found **275 targets and zero missing paths**. Existing coverage-neutral / post-T-011 wording is an explicitly reserved T-035 correction immediately next, not a new T-036 finding. Known T-038 HIGH remains separate and is neither cleared nor reopened by this CI review. Historical roadmap banners and Round 1 reports retain point-in-time statements with reconciliation/current status provided explicitly. + +## Integration + +**Clean; no finding.** All seven cache exact keys and restore prefixes were checked individually: cargo host (lines 99/101), cargo-aarch64 (156/158), qemu-smoke (234/236), arm64-host (304/306), stable (354/356), Miri (393/395), llvmcov (444/446). All **14** include `${{ runner.os }}-${{ runner.arch }}`; no broad fallback crosses Linux x86/ARM. Distinct job namespaces remain separated. Lock hashes occur in exact keys; restore prefixes intentionally permit earlier lockfile caches within the same OS/architecture/job/toolchain namespace. The stable namespace remains rolling as before. The private rejection probe never uses the workflow shared target cache. + +CI security remains within the existing disposable hosted-runner model: global `contents: read`; full-SHA checkout with `persist-credentials: false`; full-SHA cache; no new secrets, writable token scopes, publishing, pull_request_target, untrusted expression injection or self-hosted/privileged service. No `continue-on-error` weakens any ARM command/probe. Explicit Bash preserves pipe failures in host verification; the negative harness isolates its single intended failure with explicit status/diagnostic checking. The new job runs on normal push and PR triggers. Existing x86 host/stable/Miri, kernel, QEMU and informational coverage jobs retain their behavior apart from architecture cache segregation. Cache state is not claimed as an authenticity boundary. + +No new Cargo dependency/lockfile change, binary blob, ABI/public API change, shipped TCB growth or audit-log obligation exists. T-037's correct target gating already exists in the baseline; this job adds independent detection. This review does not change live protection. Repository evidence and coordinator context identify the five already registered checks; independent live API read-back is not claimed by this reviewer. ARM registration should follow both fresh rounds and preserve the existing checks/source-app binding, then receive its own read-back evidence. + +| Principle | Disposition | +|---|---| +| P1 No ambient authority | Pass: no runtime privilege change; read-only CI token. | +| P2 Smallest TCB | Pass: no shipped kernel/TCB growth. | +| P3 Userspace drivers/services | Unchanged: no subsystem placement/fault-boundary change. | +| P4 Boundary capability checks | Unchanged at runtime; CI host/probe boundaries fail closed. | +| P5 Rust kernel | Pass: shipped Rust/assembly unchanged; shell/Python are tooling. | +| P6 HAL separation | Pass: only BSP excluded from host checks; host tests do not claim device execution. | +| P7 No proprietary blobs | Pass: none added or required. | +| P8 ADR governance | Pass: Accepted ADR-0040 authorizes policy and staged review/registration. | +| P9 English repository | Pass: changed source/docs/commits are English. | +| P10 Mermaid diagrams | Not applicable: no diagram added. | +| P11 Reproducibility | Pass: pin/actions retained; all exact/fallback architecture boundaries preserved. | +| P12 Complete scope | Pass for implementation review: commands/probe/docs complete; live/final PR/main evidence remains pending rather than certified. | + +Standard code-review checklist: correctness/pass; capability semantics/unchanged; fault containment/unchanged; unsafe/no change or new audit requirement; error handling/pass through independent fail-closed controls; test coverage/pass with actual/stub/inspected evidence separated; documentation/pass with Round 1 Low verified fixed; architectural principles/all twelve covered; dependencies/no additions; naming/style/pass; commit format/pass. The ordinary risk classification follows the actual change, not the sensitivity of unchanged baseline code copied by a negative experiment. + +## Verdict + +**Approve — zero new findings at Critical, High, Medium or Low severity.** All five roles and the complete applicable checklist were reassessed independently at immutable `5c95cd3ab2bd97847ef3951b16c59d47563588e3`; the Round 1 Low is corrected. No in-scope blocker was found. + +This recommendation is for the reviewed tip only. It is not a Done-promotion, maintainer final approval, live administrative-action approval or first-main certification. Complete canonical Round 2 integration, the separately sequenced live ARM registration/read-back, final maintainer PR green/review and first merged-main evidence as required; T-036 remains In Review. + +## Round 2 — fresh independent integration + +# Code review 2026-10-12 — T-036 Step 7 Round 2, independent integration/test/documentation + +- **Change:** `development`, baseline `9c5191cfb8ced7e99e1afe459bb02852fde1a14b` → immutable reviewed tip `5c95cd3ab2bd97847ef3951b16c59d47563588e3`. The implementation and hosted source is `bf20ec9739db635183b1b930f4da9f2c2b6813bf`; the second commit records first-round reports, the wording correction and source-bound hosted evidence. Eleven files changed overall, 363 insertions / 40 deletions. Workflow and probe bytes at the reviewed tip are identical to bf20ec9. +- **Reviewer:** fresh independent Codex delegated reviewer `/root/b21_step7_round2_integration`, acting on behalf of @cemililik. All five master-plan roles performed sequentially. This is a review recommendation, not maintainer approval, a Done promotion or live policy read-back. +- **Risk class:** Ordinary CI/tooling/docs-only change. No shipped Rust, assembly, capability, IPC, syscall, memory, scheduler, boot, public API, manifest, lockfile or production unsafe modification. Separate security artifact is not required; CI trust boundaries were reviewed below. +- **Security-review cross-reference:** n/a for this ordinary change. Existing T-038 HIGH syscall-register clobber work is explicitly outside this verdict. +- **Process:** Read AGENTS.md, full CLAUDE.md, current roadmap, every existing numbered ADR in numerical order through 0040 (0034 intentionally reserved), all fifteen standards, perform-code-review and conduct-review skills, complete code-review master plan, full canonical first-round report `docs/analysis/reviews/code-reviews/2026-10-12-t036-native-arm-ci.md`, task, workflow, probe and relevant Cargo/userland configuration. Bounded follow-up reads recovered truncated corpus output. Accepted ADR-0040 governs this step and its stacked-sequence review exception. No repository write, branch, commit or live settings operation was performed. Requested temporary-only scope leaves canonical filing/index integration to the coordinator. + +## Correctness + +**Clean; no new finding.** + +The native job uses `ubuntu-24.04-arm`, a 15-minute timeout, explicit Bash, and the pinned `nightly-2026-01-15`. It installs clippy and Miri and sets that exact override before the probe's unqualified Cargo call. Before commands, both `uname -m = aarch64` and `rustc` host `aarch64-unknown-linux-gnu` must pass. There is no `--target`, global Cargo build target or host Rustflags redirecting this gate into cross-compilation. The actual hosted log confirms those host checks ran successfully rather than merely existing as YAML text. + +The four mandatory commands are exact: + +```sh +cargo +"$NIGHTLY_PIN" check --workspace --exclude tyrne-bsp-qemu-virt +cargo +"$NIGHTLY_PIN" clippy --workspace --exclude tyrne-bsp-qemu-virt --all-targets -- -D warnings +cargo +"$NIGHTLY_PIN" test --workspace --exclude tyrne-bsp-qemu-virt +cargo +"$NIGHTLY_PIN" miri test --workspace --exclude tyrne-bsp-qemu-virt +``` + +`cargo +"$NIGHTLY_PIN" miri setup` precedes interpretation. Only the BSP is excluded. Both `tyrne-user` and `tyrne-userland-hello` remain workspace members despite their absence from default-members, and both host harnesses occur in the hosted native and Miri logs. Positive native compilation/linking/execution and Miri are separate checks. Host results cannot certify bare-metal entry/SVC/MMIO or QEMU behavior. + +The probe checks the Rust host before creating its temporary tree. It copies NUL-delimited tracked paths with preserved file modes, requires exactly six compound hello cfg predicates, replaces those six only in the private main.rs and keeps build.rs and the syscall shim unchanged. Its private Cargo target stays beside the private tree; EXIT cleanup removes both. It then executes the exact workspace all-targets clippy command. Nonzero status plus the fixed E0152 duplicate-panic_impl diagnostic is required. Unexpected compiler success and unrelated compiler failure both fail the harness. Compiler exit 101 and successful harness exit 0 are correctly distinguished; no production Miri failure is claimed by this deliberate compile rejection. + +The T-037 compound target gating is already in the baseline and remains unchanged. Native hosts therefore receive the ordinary std hello stub and avoid the bare-metal linker script. The negative mutation isolates the original architecture-only predicate hazard without broadening into build-script or wrapper mutations. + +## Style + +**Clean.** Independently ran actionlint, ShellCheck for the changed script, Bash syntax checking and `git diff --check 9c5191c 5c95cd3`: all passed. New YAML follows existing SHA-pinned actions and toolchain conventions. The literal-diagnostic ShellCheck suppression is narrow and justified. Shell paths and variables are quoted; argument and failure handling are explicit. No Rust public item, unsafe block, error type or audit entry was added. + +Both commits are English and use Conventional Commit form, with relevant ADR trailers. The follow-up documentation commit links its canonical review. No stylistic preference is promoted to a finding. + +## Test coverage + +**Adequate; no missing blocking test.** Fresh work focused on the unchanged harness and infrastructure failures, rather than repeating the already evidenced entire host/Miri/QEMU suite for a documentation follow-up. + +### Fresh independent actual execution + +Exported exact tip with `git archive` to `/tmp/tyrne-t036-r2-integration/frozen source`, containing 394 regular files. Only git tracked-file enumeration was supplied privately for the archive; actual rustc/Cargo were used, with private Cargo home and temporary target/tree. Actual host was `aarch64-apple-darwin`; installed compiler reported `rustc 1.94.0-nightly (86a49fd71 2026-01-14)`. Running `/bin/bash tools/test-ci-gates.sh --arm-host` produced the expected clippy exit 101 / E0152 diagnostic and harness exit 0. All archived regular-file hashes were unchanged afterward and the private temporary parent was empty. No shared userland image was produced or replaced. + +Fresh logs and controls: `/tmp/tyrne-t036-r2-integration/real-negative.log`, `run-controls.py`, `results.json`, and per-case `output.log` files. The real-negative log intentionally contains the harness's recorded rejection summary; the harness captures the underlying compiler stream in its disposable tree and removes it on cleanup. Actual tool identity was independently checked before the run. No Linux execution is inferred from this local run. + +### Fresh controlled failure paths + +Nine private cases use stub rustc/Cargo and are explicitly harness controls, not compiler or Linux evidence: + +| Controlled case | Harness exit | Cargo called | Result | +|---|---:|---|---| +| Intended E0152 rejection | 0 | Yes | Accepts the intended assertion | +| Unexpectedly green command | 1 | Yes | Refuses false green | +| Unrelated compiler error | 1 | Yes | Refuses unrelated failure | +| x86 Rust host | 1 | No | Refuses wrong host | +| Five instead of six cfg anchors | 1 | No | Refuses source drift | +| rustc tool failure | 42 | No | Propagates infrastructure failure | +| Missing Rust host field | 1 | No | Refuses incomplete identification | +| Python mutation failure | 43 | No | Fails before Cargo | +| File-copy failure | 43 | No | Fails before mutation/Cargo | + +Every case preserved its original source hashes and left its temporary parent empty. Cargo-capable controls asserted exact argv, all-six mutation, unchanged build.rs and syscall shim, executable script preservation and a private Cargo target. Paths contain spaces. The fixture uses absolute interpreter paths so injected Python failure reaches the mutation invocation rather than breaking the tool stubs. Its `/tmp` versus `/private/tmp` comparisons use resolved paths; an initial fixture assertion was corrected for that macOS alias before the complete passing run. Those fixture corrections did not change repository source. + +### Independently inspected existing hosted evidence + +I independently read the provided `/tmp/tyrne-b21-step7/hosted-run.json` and relevant `/tmp/tyrne-b21-step7/hosted-arm.log` evidence. I did not launch or fetch a new hosted run and did not execute Linux locally. + +JSON reports completed success for all seven jobs in run 38184932784: ARM, coverage, QEMU, kernel, x86 Miri, stable and lint/host tests. ARM job 114605118899 spans 101 seconds by API timestamps; check/clippy/negative/native tests/setup/Miri are 1/1/7/4/17/54 seconds. These second-granularity figures are execution records, not benchmarks. + +The ARM log binds the checkout to full source bf20ec9 at lines 92–106 and records installed pinned compiler, actual aarch64 machine and Linux Rust host at 127–148. Exact commands occur at 170–205 and 639–692. The rejection summary at 203 records exit101/E0152. Native and Miri each pass 46 HAL + 259 kernel + 58 test-HAL + 3 doctests = 366 tests, with two ignored HAL doctests. Both userland host harnesses build/run with zero tests. Miri paths are `target/miri/aarch64-unknown-linux-gnu`; setup and interpretation are separate successful steps. Existing Miri optimization/provenance warnings do not report UB, and successful interpretation proves the exercised paths only. [Hosted ARM job](https://github.com/HodeTech/Tyrne/actions/runs/38184932784/job/114605118899). + +The canonical first-round report separately records prior actual Apple Silicon positive check/clippy/test/Miri execution and its raw logs. That is inspected prior evidence, not a fresh positive-suite execution by this reviewer. The byte-identical workflow/probe between hosted source and reviewed tip makes that hosted evidence applicable to the implementation; it does not constitute a hosted run of the follow-up documentation SHA. + +## Documentation + +**The duplicate Round 1 Low is fixed; no new finding.** At `docs/standards/testing.md:111`, the ARM bullet still appears beneath the enforced-gates heading but now explicitly states that the workflow is enabled and live required-check registration awaits hosted green and both fresh rounds. Together with the guide, infrastructure's separate pending ARM display name, task unchecked live criterion and current pointers, this removes the premature claim that the new workflow itself already blocks merge. The hosted prerequisite has now been satisfied; live registration and the two-round process remain separately recorded rather than inferred. + +The reviewed follow-up records source-bound hosted success and measured timing honestly. Task/current/index remain `In Review`; task final-PR green, first merged-main run and live registration are unchecked. The canonical first-round reports preserve immutable bf20ec9 findings and add a reconciliation/correction rather than silently rewriting what those reviewers saw. Both first-round reports were read in full. + +Guide commands, only-BSP exclusion, native-versus-guest boundary, mandatory Miri, private arch-only experiment, intended display name and registration sequence match source. Relative file targets in all changed Markdown were checked independently: 275 resolve, with the documentation's literal `](...)` example excluded. This file-existence check does not validate every heading fragment or external link. No changed heading introduces a newly broken fragment in the examined links. + +The pre-existing coverage-neutral/post-T-011 prose is expressly reserved for immediately next T-035 under the accepted sequence. It is not a new T-036 finding. The host evidence neither resolves nor downgrades T-038's separate HIGH clobber issue. + +## Integration + +**Clean; no integration blocker.** All seven jobs remain. Existing x86/stable/Miri/coverage/cross-build/QEMU command behavior is retained; the only changes in their implementations are architecture-separated cache identities. Native ARM is additional coverage, not a substitute for those jobs. + +All seven actions/cache blocks and all 14 exact-key/restore-prefix lines were independently checked: + +| Namespace | Exact key | Restore prefix | +|---|---:|---:| +| cargo host | 99 | 101 | +| cargo-aarch64 kernel | 156 | 158 | +| qemu-smoke | 234 | 236 | +| arm64-host | 304 | 306 | +| cargo-stable | 354 | 356 | +| miri | 393 | 395 | +| llvmcov | 444 | 446 | + +Every exact key and every fallback starts with `${{ runner.os }}-${{ runner.arch }}-`, followed by a distinct job namespace. Pinned namespaces retain nightly identity; stable retains its prior rolling-stable namespace. Exact keys retain lock hashes; restore prefixes deliberately allow an older lock cache within the same OS/architecture/job/toolchain namespace. No broad fallback can restore x86 build state onto ARM. The negative probe bypasses that shared target via its private target tree. + +CI security: unchanged top-level `contents: read`, fully SHA-pinned checkout/cache actions, and all checkouts retain `persist-credentials: false`. No secrets, new action dependency, admin token, privileged service, self-hosted runner, writable token scope, pull_request_target trigger, publishing or live-policy mutation is introduced. Shell source does not interpolate untrusted PR content. Explicit Bash preserves pipeline failure; ARM has no continue-on-error and no condition skipping a required positive step. Expected compiler failure is narrowly handled and authenticated by diagnostic rather than treated as arbitrary success. Bounded timeout limits a hang. Cache state remains a performance/build input, not an authenticity claim. + +### Architectural principles P1–P12 + +| Principle | Assessment | +|---|---| +| P1 No ambient authority | Pass: runtime unchanged; CI token remains read-only. | +| P2 Smallest defensible TCB | Pass: no shipped TCB growth; bounded host tooling only. | +| P3 Userspace drivers/services | Unchanged: no placement or fault-boundary move. | +| P4 Checks at boundaries | Pass within scope: host/source-anchor/failure controls fail closed; no runtime boundary changed. | +| P5 Rust-only kernel | Pass: no kernel-language change; Bash/Python remain host tooling. | +| P6 HAL separation | Pass: only inherently bare-metal BSP excluded; hardware behavior remains separate evidence. | +| P7 No proprietary blobs | Pass: none added, embedded or required by this delta. | +| P8 ADR governance | Pass: Accepted ADR-0040 precedes runner/command/Miri/registration policy and standards changes. | +| P9 English repository | Pass: changed artifacts and commits are English. | +| P10 Mermaid diagrams | N/a: no diagram changes. | +| P11 Reproducibility | Pass within scope: exact nightly/action pins retained, lock identities retained, every fallback separates architecture. | +| P12 Complete declared scope | Pass for implementation review: positive/negative gates implemented; live registration/review/final PR/post-merge remain explicit process obligations. | + +### Full standard checklist + +- Correctness: pass, native target and probe assertions verified. +- Capability semantics: unchanged; no authority/handle/right behavior touched. +- Fault containment: runtime unchanged; probe isolation and cleanup verified. +- Unsafe: no production Rust/unsafe change; no SAFETY/audit/security-approval obligation created. +- Error handling: pass; tool, copy, mutation, unrelated compiler and false-green controls fail closed. +- Tests: pass; actual local negative, fresh controlled cases, syntax/lint checks and inspected source-bound hosted positives clearly distinguished. +- Documentation: pass; Round 1 Low corrected, pending obligations retained, file targets resolve. +- Architecture: all P1–P12 assessed above; no new decision beyond Accepted ADR-0040. +- Dependencies: no manifest/lock/dependency/blob additions. +- Style: pass; actionlint, ShellCheck, Bash syntax and whitespace clean. +- Commit format: pass; English Conventional Commits and ADR/review trailers. +- Review artifact/index: coordinator integration deferred by explicit temporary-report-only assignment. + +## Verdict + +**Approve.

It expressly excludes the existing T-038 x2 defect. +- **Cycle state:** round 1 recorded; the second fresh code/security round remains pending. This artifact is not a Done-promotion, merge-readiness, or maintainer-approval verdict. + +## Correctness + +**Clean for the reviewed implementation.** The reviewer first read T-037's opening baseline, acceptance criteria, review history, the prior [preflight](2026-10-11-phase-b2-track1-preflight.md), and the [ADR-0040 approval follow-up](2026-10-11-adr-0040-approval-follow-up.md). The implementation was then read in dependency order: userspace types/constants/wrappers, hello's target build selection, and the hello caller/entry/panic/host paths. Complete changed source files, manifests, Cargo target flags/aliases, linker script, build pipeline, and affected CI command definitions were inspected. + +All 13 userland Rust cfg gates require `all(target_arch = "aarch64", target_os = "none")`; the three host stub gates use its exact negation. On ARM desktop hosts, hello therefore selects ordinary `std` and `main`, while `tyrne-user` remains `no_std` with its pre-existing safe host stubs. The build script reads Cargo's **target** architecture and OS environment, rather than the build-script binary's host cfg. Its linker decision agrees with the source gates and the BSP's established predicate. + +The diff changes no syscall number, capability word, public signature, SVC instruction, assembly operand, return/error branch, panic behavior on the bare-metal target, or entry/link section. Debug image bytes are independently preserved. The known input-only x2 defect is unchanged and remains [T-038](../../tasks/phase-b2/T-038-console-write-x2-clobber.md)'s owner; passing tests and an unchanged image do not certify its soundness. + +## Style + +**Clean.** Rustfmt and workspace clippy with warnings denied pass. The inline predicate requires no custom cfg registration, dependency, or new build configuration. Comments explain why ARM host architecture is insufficient and cross-reference the other two userland gates and the BSP gate. No preference-only refactor is requested. + +## Test coverage + +**Clean for this step's declared scope.** The existing workspace compilation/test commands exercise the broken ARM host selection directly. An isolated before/after test-harness compilation reproduced the pre-fix duplicate panic handler and demonstrated that the current hello source compiles with the same native compiler/dependency arguments. The build-script matrix independently checks both axes and missing variables. Bare-metal build/hash and QEMU trace checks cover the retained target path. + +Commands executed independently on Apple Silicon, host `aarch64-apple-darwin`, pinned `nightly-2026-01-15` (`rustc 1.94.0-nightly`, commit `86a49fd71`, LLVM 21.1.8): + +| Command / check | Result | +|-----------------|--------| +| `cargo check --workspace --exclude tyrne-bsp-qemu-virt` | PASS | +| `cargo clippy --workspace --exclude tyrne-bsp-qemu-virt --all-targets -- -D warnings` | PASS | +| `cargo test --workspace --exclude tyrne-bsp-qemu-virt --quiet` | PASS: 46 HAL + 259 kernel + 58 test-HAL + 3 doctests = **366**; two pre-existing HAL doctests ignored | +| `cargo fmt --all -- --check` | PASS | +| `tools/build-userland.sh` | PASS; debug image **117 bytes** | +| `shasum -a 256 userland/hello/hello.bin` and `wc -c userland/hello/hello.bin` | **117 bytes**, SHA-256 `05816ccb9be5caea862dbe3e0fc45fc2068ff06cd049f2dda3459492d0ef7d88` | +| `cargo kernel-build` | PASS | +| `cargo kernel-clippy` | PASS | +| `tools/smoke.sh --int --timeout 5` | PASS; trace manually checked for greeting, userspace exit, completion, exactly two SVCs, and no panic/fault | +| Compiled `userland/hello/build.rs` matrix | PASS: linker argument present only for aarch64/none; absent for aarch64/macos, aarch64/linux, x86_64/linux, x86_64/none, and both target variables missing.

This is not whole-PR completion, Done promotion or merge authorization. + +## Scope and prerequisites + +Security relevance is evidence integrity, failure classification, local administrative-policy validation, diagnostic confidentiality and CI supply-chain exposure. The 14-file delta adds a captured REST policy fixture/two tests, a clean ARM clippy baseline and empty-diagnostic guard/two fixture methods, the actual instruction-fault token, optional performance metadata fallbacks/privacy minimization/one fixture method, five cache-path deletions, one guide paragraph and three append-only task-history rows. All 14 changed files were inspected; tests were read before their implementations. + +Read AGENTS guidance, full CLAUDE/current roadmap, all actual numbered ADR files in numerical order (0001–0033, 0035–0040; no 0034 file), all 15 files under standards including the index, both relevant skills, the complete security master plan/security model/unsafe audit log, the complete previous T-035 security review, and the supplied PR48 report. Large-output truncations were recovered with smaller bounded reads. The report's claims are assessed independently rather than adopted as instructions. ADR-0040's accepted consolidation policy is unchanged. + +The complete range has no Rust, assembly, Cargo manifest/lock, ADR, unsafe-log, production protection-adapter or protection-definition change. Existing runtime trust boundaries and T-038 are not newly re-audited or cleared by these host-tool results. All eight Track B.2-1 tasks remain In Review. Follow-up B's remaining documentation/reconciliation work, second fresh review round, final maintainer review, first merged-main runs and default-branch performance dispatch remain pending. + +## 1. Capability correctness + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S01 — Every privileged operation requires authority | Can this patch let an unprivileged caller change main protection? | **OK for host boundary; N/A to new runtime operations.** The adapter and six-check definition are byte-unchanged. Only explicit local apply uses existing GitHub administration authority; fixtures make no live calls and workflows gain no permission. | +| S02 — Narrowest sufficient authority | Can the new fixture redirect the administrative target or widen policy writes? | **OK.** Fixture data is read offline and normalized against the fixed HodeTech/Tyrne main definition; production fixed endpoints and narrow status-check PATCH remain unchanged. No admin credential enters CI. | +| S03 — Authority checks before effects | Can an unknown captured-response extension reach a write? | **OK.** Exact schema/type checks remain in production. Twenty additional mutated captured-response cases refused before any fake write, even for null/false/empty-looking extensions. The actual fixture must equal the entire canonical normalized policy. | +| S04 — Move-only transfer | Can this change duplicate a transferred runtime capability? | **N/A.** No capability representation, IPC transfer or ownership operation changes. | +| S05 — Explicit duplication authority | Can new tooling mint duplicate capability rights? | **N/A.** No duplication operation or rights bit changes; host processes retain their existing operator authority. | +| S06 — Atomic revocation | Can a caller observe partial runtime revocation? | **N/A.** No revocation path changes. The pre-existing administrative read/PATCH/readback sequence remains non-atomic and is not misrepresented as a capability revocation transaction. | + +The adapter remains a guardrail for trusted local maintenance, not a sandbox for a compromised administrator or host. CI refusal cannot prevent an administrator from using GitHub directly. The existing zero approving-review count and disabled admin enforcement are preserved exactly; no silent policy tightening or weakening was performed. + +## 2. Trust boundaries + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S07 — Validate userspace inputs before kernel use | Can malformed input cross a newly weakened parser? | **N/A to kernel; OK for host analogue.** No syscall parser changes. The captured protection endpoint response is validated with the existing exact schema; unsupported fields are still rejected. | +| S08 — User pointers need validated mappings | Can a supplied address become a privileged dereference? | **N/A.** No user pointer, address-space map, copy-user path or kernel dereference changes. Host GitHub transport still uses argv/stdin JSON, not shell interpolation. | +| S09 — Bound user lengths against mapped regions | Can a length overrun a mapped buffer or incomplete evidence masquerade as complete? | **N/A to memory; OK for retained host evidence contract.** No buffer consumer changes. Existing check evidence length/total/100-entry ceiling tests pass; partial performance samples remain explicitly counted. | +| S10 — Typed message parsing | Can policy-bearing fields or unrelated compiler errors be accepted as harmless metadata? | **OK.** New policy tests reject enforcement and actor fields instead of stripping them. ARM accepts only exit 101 plus one exact full diagnostic line after an identical clean command succeeds. Empty expected diagnostic and tested near matches fail. | +| S11 — IPC grants no excess authority | Can a sender transfer rights it does not hold? | **N/A.** IPC, capability tables and rights transfer are unchanged. Offline policy normalization does not create authority. | + +**REST fixture and fail-closed policy.** `tools/fixtures/main-protection-2026-10-12.json` is a complete observed body for the protection endpoint, including URL metadata and context ordering. Independently parsed and compared it with the parent-supplied read-only capture: equal. Normalization with the separately versioned GraphQL rule equals the entire canonical definition, including all six app-bound checks and non-status fields. Capture acquisition is the parent's action; the committed fixture is a dated sample, not live drift attestation. Neither the adapter nor policy changed. + +The supplied report's M-3 broad metadata-dropping suggestion is not justified: dismissal/bypass actors and enforcement scope are policy. Branch-summary `name`/`protection_url` cannot establish that those keys belong to the protection endpoint. The new tests intentionally refuse them. An unexpected future endpoint shape can stop maintenance until reviewed adaptation; availability loss is preferable to silent policy loss. This fixture does not claim to model every supported GitHub response or replace the GraphQL/ruleset reads. No live administrative mutation was run to discover behavior. + +**ARM attribution.** `tools/test-ci-gates.sh:83–110` defines the exact clippy command once, checks all six original cfg anchors, runs it on an unmodified private copy/private target, refuses any clean-baseline failure, then replaces exactly those six predicates and runs the same command. Build script and syscall shim are preserved. Exit 101 plus either exact E0152 duplicate-panic line or exact no_std unwind line remains required; unrelated errors, tool statuses, successful command exits and empty diagnostics fail. The baseline closes the specific false-attribution route where an already-broken source emitted a recognized class before mutation. It does not formally prove causal isolation from nondeterministic external failures or a hostile compiler; a diagnostic coinciding with a new unrelated failure could still exist. This is a controlled regression assertion under trusted tools, not compiler-output attestation. + +**Smoke boundary.** Both real smoke and synthetic faults now use `Undefined Instruction`, the producer spelling documented in the BSP boot checklist. Independent synthetic traces in both profiles contain the completion markers plus that fault and correctly fail, so success markers cannot hide it. Hosted artifacts contain those cases. This is not a proof of exhaustive CPU exception detection, exact SVC counts or adversarial EL0 behavior; those remain outside this delta. + +## 3. Memory safety + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S12 — New unsafe satisfies policy | Can new unsafe escape SAFETY/audit review? | **N/A.** No production Rust/assembly or unsafe body/contract changes. Shell/Python host tools do not create a new unsafe audit entry. | +| S13 — Safety invariants at every caller | Can these passing gates wrongly certify an existing unsafe contract? | **Flagged — existing excluded HIGH T-038.** The input-only x2 syscall-shim mismatch is unchanged and not endorsed. No new unsafe caller broadens its contract; this scoped approval leaves the HIGH open. | +| S14 — No uninitialized memory exposed | Can new partially filled memory reach a task or log? | **N/A to runtime.** No kernel buffer initialization changes; failed optional metadata is replaced with explicit unknown rather than retained partial command output. | +| S15 — No use-after-free | Can changed ownership or cleanup destroy live source? | **N/A to pointers; OK for host isolation.** Probe copies use a fresh temporary directory/private Cargo target and quoted cleanup. Fixtures verify four original files' hashes and empty scratch after success/refusal/copy failure. | +| S16 — No aliasing violations | Can a borrow now cross a context switch or race? | **N/A.** Rust references, context switches, locks and memory ownership are unchanged. Private experiment copies do not share production build outputs. | + +Read the complete audit log for reconciliation and checked the exact diff for absence of unsafe/SAFETY/audit changes. This is an applicability check, not a fresh sign-off of every historical audit argument. Known old claims are interpreted with their amendments and T-038 exclusion; a clean host compiler/Miri run cannot clear architecture assembly defects. + +## 4. Kernel-mode discipline + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S17 — No ISR allocations | Can interrupt delivery allocate through a new report path? | **N/A.** Reporting and probes run on the host; no ISR path changes. | +| S18 — No unbounded kernel loops | Can an input newly stall the guest kernel? | **N/A.** Kernel loops are unchanged. The existing finite measurement count, per-guest watchdog and hosted job timeouts remain; optional metadata fallbacks add no retry loop. | +| S19 — Minimize critical sections | Can clippy/API waits hold a kernel lock? | **N/A.** No scheduler state, IRQ masking or critical-section changes. | +| S20 — No hot-path kernel panic | Can the intentional panic-handler regression enter shipped code? | **N/A to changed runtime; OK for tooling separation.** The regression exists only in the disposable hello copy, with unchanged shipped predicates. A baseline failure aborts before mutation. | +| MP-33 — Typed allocation-exhaustion error, not panic | Can resource exhaustion now panic the kernel? | **N/A.** No kernel allocation path, arena quota or exhaustion error changes. Host disk/memory exhaustion is not treated as evidence of a passing compiler rejection. | + +The extra clean clippy run costs bounded CI time; native actual execution and hosted ARM success demonstrate feasibility at this source. Successful synthetic metadata does not mean a missing QEMU can run a guest: fallback only handles metadata collection, while missing measurements still fail the existing threshold. No timing-regression threshold or required performance check is introduced. + +## 5. Cryptography + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S21 — Reviewed primitives, no homemade crypto | Can a new algorithm forge evidence or rights? | **N/A.** No cryptographic primitive/protocol is introduced. SHA identifiers/digests are provenance references, not a new authentication scheme. | +| S22 — Keys absent from logs/errors/Debug | Can optional metadata errors expose key material? | **OK for applicable diagnostics.** Four metadata commands suppress stderr and discard partial stdout on failure; independent canary tests verify neither stream's secret-like text survives. No new key handling exists. | +| S23 — Constant-time comparisons | Can a secret comparison leak timing? | **N/A.** Comparisons involve public policy, compiler diagnostics, identifiers and sample counts; no secret equality operation changes. | +| S24 — Acceptable randomness | Can weak randomness mint predictable authority? | **N/A.** No key/token/nonce generator changes. Temporary isolation uses existing platform mktemp/TemporaryDirectory mechanisms. | +| S25 — Correct nonces/IVs/salts | Can reuse break authentication? | **N/A.** No encryption, nonce, IV or salt state is introduced. | + +## 6. Secrets and logging + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S26 — No secrets in diagnostics | Can normal provenance expose the private checkout path/hostname, or failures preserve sensitive partial output? | **OK within the specified minimization boundary.** Report uses `uname -srm`; rustup explanation is removed after the first space while the normal version/host identifier remains. Failed commands become `(unknown)` with stderr suppressed; independent tests check both streams. No credential store/environment dump is added. | +| S27 — Sensitive Debug redacts/absent | Can a changed formatter expose capability bits? | **N/A to Rust Debug; OK for host representation change.** No sensitive Rust type changes. The report removes unnecessary local identity fields, with explicit unknown metadata and source-state provenance retained. | + +`tools/perf-harness.sh:251–264` handles failures of uname, QEMU-version, rustc and rustup commands separately from valid measured samples. Normal toolchain identifiers retain reproducibility value; the override explanation can contain private checkout paths and is dropped. Nonzero metadata commands cannot publish their partial stdout as a successful field. The seven permanent methods include status 1/127 cases, privacy assertions, sample counts, overwrite refusal, dirty/unknown Git state and failed measurement propagation through explicit Bash/tee. Custom tests additionally send canaries on stderr and stdout together, testing the report and process output. + +This is minimization of the reported normal host/toolchain fields, not universal arbitrary-output sanitization. A custom toolchain identifier itself can contain operator-chosen identifying text; command output from compromised tools is outside the trusted-tool model. Existing archived reports are unchanged and remain historical; follow-up B must reconcile the supplied report's documentation concerns rather than retroactively relabel them. The unchanged hosted workflow separately captures raw toolchain/version files on a disposable public runner. The inspected newly generated report omits override explanation and hostname; this does not promise that every auxiliary artifact or every historical report has been redacted. + +## 7. Dependencies + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S28 — Dependency policy followed | Does this patch pull in unaudited third-party code? | **OK.** No dependency/toolchain/action pin changes; Python uses stdlib and existing Bash tools. Five executable cache paths are removed. | +| S29 — Trust category understood | Can cache data silently replace installed executables or be mistaken for runtime trust? | **OK for reduced surface.** Changed caches omit cargo-bin while preserving registry/git/target caches. Tool installation remains explicit and action/toolchain pins unchanged. Existing build-cache trust remains; this is not hermetic build attestation. | +| S30 — cargo-vet updated as required | Is a new kernel-linked crate unaudited? | **N/A.** Cargo graph and lockfile are unchanged; no new cargo-vet decision or claim of running cargo-audit/vet. | + +The workflow diff is exactly five deletions of `~/.cargo/bin`; keys, restore prefixes, registry/git/target paths, job permissions, triggers and commands remain unchanged. Rust toolchains are explicitly installed before the affected caches. Coverage explicitly installs pinned cargo-llvm-cov; smoke/performance/coverage already omitted bin. All cache keys/prefixes retain OS and architecture separation; restore prefixes intentionally need not contain a lockfile hash. + +Cache matching includes version as well as key/branch, and version incorporates the cached path list and compression. Thus the changed path list separates the old bin-containing cache version even with unchanged textual keys; this is an inference from the pinned action's documented semantics, not a live cache inventory or destructive cache experiment. [Pinned actions/cache v4.2.3 README, Cache Version](https://raw.githubusercontent.com/actions/cache/5a3ec84eff668545956fd18022155c47e93e2684/README.md), [GitHub cache matching reference](https://docs.github.com/en/actions/reference/workflows-and-actions/dependency-caching#cache-key-matching). + +No historical caches were deleted. Registry/git/target remain trusted build inputs and can contain generated executable build artifacts; omission of bin reduces one overwrite surface and does not eliminate all cache poisoning possibilities. Hosted-source execution itself remains trusted only to the workflow's existing privilege boundary. The retained coverage comment incorrectly contrasts its omission with siblings; R1-SEC-01 records that narrow documentation defect below. + +## 8. Threat-model impact + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S31 — Reconciled with security model | Can host evidence falsely weaken runtime isolation or repository protection? | **OK for scoped delta.** No runtime principal, authority, MMU/IPC/DMA boundary changes. Evidence becomes more conservative: clean baseline, exact fault token, retained policy refusal, explicit unknown metadata and smaller executable cache surface. | +| S32 — Model changes documented/tracked | Is a new trust assumption hidden or a planned policy change silently applied? | **OK.** ADR-0040 policy is byte-unchanged. Host compiler/cache/admin assumptions and non-atomic maintenance limits remain. Follow-up B's producer-app boundary explanation is still pending; no CODEOWNERS/reviewer/admin policy change is silently adopted. | + +The supplied M-2 assertion is not established here as a demonstrated hosted duplicate-name bypass. App ID identifies a check producer, not the integrity of its workflow's contents; trusted workflow review remains an actual boundary to document in B. The adapter separately rejects duplicate name matches in the evidence it uses to authorize adding a check. That local API guard is not a theorem about GitHub's merge enforcement. We neither conflate those boundaries nor claim that a trivial duplicate hosted job was proven to bypass the required job. + +The existing final reread/full readback narrows but cannot remove another-administrator races: separate policy reads and PATCH are not atomic compare-and-swap. That accepted local-maintenance limitation is unchanged; no live apply was performed. Performance remains informational, separate from required smoke, with failed measurements failing workflow execution and no calibrated merge threshold. Schedule/dispatch on the default branch and first merged-main proof remain merge-dependent. + +## Findings + +### R1-SEC-01 — Low, nonblocking: stale sibling-cache contrast + +- **Location at reviewed head:** `.github/workflows/ci.yml:438–440`. +- **Evidence:** coverage's cache comment still says bin is omitted “unlike the sibling jobs,” but this delta removes all five remaining sibling cargo-bin paths. The comment now misstates the reviewed cache boundary. +- **Impact:** documentation/post-fix-sweep inconsistency; no execution, permission or policy effect. Cache removal itself is security-positive within the limits above. +- **Required correction:** remove the contrast and describe explicit tool installation and bin omission consistently. +- **Owner/status:** coordinator verified the finding and plans an A round-1 correction before fresh round 2. **Open at immutable 50ab**; a future change is not certified by this report. This does not block scoped security approval. + +No new High/Medium security defect or blocking finding was established. T-038 remains a pre-existing excluded HIGH, not a newly waived minor finding. Other supplied-report documentation matters remain assigned to planned follow-up B; this verdict does not silently close them. + +## Architectural principles P1–P12 + +| Principle | Disposition and justification | +|---|---| +| P1 — No ambient authority | **OK.** No runtime grant or CI administration authority added; local admin adapter unchanged. | +| P2 — Smallest defensible TCB | **OK.** Host tooling only; no kernel TCB increase. | +| P3 — Drivers/filesystems/network in userspace | **N/A.** No runtime placement changes. | +| P4 — Capability checks at every boundary | **OK for host analogue.** Unknown policy fails before writes; runtime capability boundaries unchanged. | +| P5 — Rust-only kernel/justified assembly | **N/A to changed code.** Bash/Python are host tools; no unsafe or assembly contract broadened. T-038 remains HIGH. | +| P6 — HAL separation | **N/A.** No kernel/HAL dependency/interface changes. | +| P7 — No proprietary blobs | **OK.** Text fixture/scripts only; no new committed guest binary. | +| P8 — Decisions in ADRs | **OK.** ADR-0040 unchanged; corrections implement its existing policy rather than revising it. | +| P9 — English repository | **OK for delta.** New diagnostics/fixtures/comments/history are English. Remaining supplied-report language/documentation concerns belong to B. | +| P10 — Mermaid diagrams | **N/A.** No new diagram. | +| P11 — Reproducibility | **OK within evidence limits.** Toolchain/action pins and lockfile unchanged; normal toolchain identifier/source state retained; optional missing data explicitly unknown. Timings remain host-contextual. | +| P12 — No half-finished main subsystem | **OK for scoped development review.** All eight tasks stay In Review; pending A correction/R2, B documentation, maintainer review and merge-dependent evidence are not declared complete. | + +## Independent execution and provenance + +All executable checks used a private archive of the exact head at `/tmp/tyrne-pr48-security-r1.LaSkZ5`; no repository edit, checkout, branch creation, commit, live API mutation or shared image/build output was used. The private tracked-content manifest includes 407 files, SHA-256 checked after experiments with **zero changed source bytes**. Python bytecode/temp files are not production artifacts. + +The first synthetic smoke invocation stopped because a Git archive lacks `.git`; this was an environment prerequisite failure, not a passing test. For subsequent synthetic/native probes, a separate read-only Git shim answered only `rev-parse HEAD`, tracked status and `ls-files -z` from the exact immutable manifest. Status compares every archived tracked file's hash; all other Git commands are refused. Real Bash/Python/Cargo/rustc and probe source were unmodified. This supplies archive metadata without a branch/commit mutation; it is disclosed because this is not a test of Git itself. Native Cargo outputs are private to the probe's fresh temporary target and removed by its EXIT trap. + +| Independently executed check | Result and limit | +|---|---| +| `python3 tools/test-branch-protection.py`, repeated with `-O` | **29 methods pass in each mode.** Offline fake API; no administrative credentials/live transport. | +| `python3 tools/test-perf-harness.py`, repeated with `-O` | **7 methods pass in each mode.** Synthetic timing/metadata and pipeline controls, not real guest timing. | +| `python3 tools/test-arm-host-probe.py`, repeated with `-O` | **11 methods pass in each mode.** Controlled stub diagnostics, exact command/private source/target assertions, source preservation and cleanup. | +| `tools/test-smoke-gates.sh` with manifest Git shim | **20 synthetic cases pass**, completed JSON, exact smoke hash.

Fixture JSON equals parent capture. | + +The normal and optimized ARM wrapper suites spawn shebang Python stub processes normally; running the top-level suite with `-O` does not automatically propagate optimization to those child interpreters. Their top-level unittest assertions remain active. The production adapter uses explicit exceptions rather than optimization-removable assertions. Counts are test methods, not counts of real compiler runs or all subcases. + +The coordinator separately reports private new-tests/old-base controls distinguishing the old metadata failure, missing clean baseline and Undefined Instruction gap. Those are parent-executed experiments, not claimed as this reviewer's execution. Paired code review also independently performed old-code controls; its complete artifact is cross-read before finalization. + +### Reviewed source digests + +| File | SHA-256 | +|---|---| +| `tools/test-ci-gates.sh` | `34c3bc7dd449393828f122c9f203cc353e4e32fcfc6d6a6c5160815106c1e04d` | +| `tools/perf-harness.sh` | `800a5ae2d771a19ff74c47748f68d62c3295ae4fae3014dbed6b488c9737a530` | +| `tools/smoke.sh` | `cac6e377c442854384ceb9954ab664d9a0b7d95261eb0ddfb4ba98d3e1795c7a` | +| `tools/branch-protection.py` (unchanged) | `747b196e11e21340d0a7d607c7699fd129d58f9df54b96199ff6bad6907a55bd` | +| `.github/branch-protection/main.json` (unchanged) | `edd66dad0b4591c937556be55f6c473bf87e23173cde931c53347b6dc88b8a5b` | +| ADR-0040 (unchanged) | `5b82f632157033d193e64ac554390bacb9944fcd7a79fac9760a666c5f02ff2c` | + +## Parent-acquired hosted evidence independently inspected + +The coordinator acquired these service summaries/logs/artifacts; this reviewer inspected the downloaded local evidence.

This is the report file's digest; the service artifact archive digest is only parent/service-reported and was not independently recomputed. +- `/tmp/tyrne-pr48-followup/arm-50ab.log`: actual native `aarch64-unknown-linux-gnu`; exact probe prints exit 101/E0152. Native tests and Miri each total **366 passing**, with **two ignored HAL doctests**. The baseline log is not separately archived on success; the reviewed control flow plus overall probe success means it passed. No fabricated baseline stdout is quoted. +- `/tmp/tyrne-pr48-followup/smoke-50ab/*`: results name exact full 50ab, clean tracked source, smoke hash `cac6e377…`, completed true and all **23 cases passing** (20 synthetic plus three actual private kernel variants). Inspected both actual production traces: debug greeting/exit/completion; release exit/completion with no greeting; neither contains the rejected fault classes. Both new `fault-5` traces visibly contain Undefined Instruction and their results reject it. These are downloaded hosted guests, not local re-execution. +- `/tmp/tyrne-pr48-followup/main-protection-live.json`: equals the complete committed REST fixture after parsing. Parent additionally reports read-only live full-policy check pass; this reviewer did not execute any live export/check/apply. A historical capture cannot guarantee future drift absence. + +Full Rust/Miri guest-runtime suites were not independently rerun locally for this host-only delta. Hosted evidence and the actual local ARM command are accurately separated. Cache version/path semantics were checked against official documentation at the pinned action revision; the first GitHub blob fetch failed, then its raw immutable README was successfully read. No live cache deletion/poisoning experiment was performed. + +## Paired-review reconciliation and publication + +Provisional findings were sent before waiting for the peer to prevent mutual completion deadlock. The complete 125-line paired code report `/tmp/tyrne-pr48-tools-r1-code.md` was read before this security handoff. It independently Approves the exact same range with zero new blocking/High/Medium findings and the same one Low R1-SEC-01. Its reported independent read-only live check/GET, old-production regression controls and hosted API retrieval are peer evidence, not reattributed as this reviewer's actions. Its private synthetic Git commit is disclosed as fixture metadata; this reviewer used the separate read-only manifest shim described above. The findings and scope limitations agree; no further issue was found during cross-read. R1-SEC-01 was also independently noticed by the peer and coordinator, with one shared finding rather than duplicate blocker claims. + +The coordinator owns canonical artifact/index/trailer publication under this reviewer's explicit no-repository-edit constraint. This temporary full report does not claim that later recording has happened. Future corrected source and fresh round 2 remain separate. + +## Verdict + +**Approve — scoped security review of follow-up A at immutable `50ab72bf2c15a4d34be25a1491a357313e50390a`.** + +All eight axes, all 33 checklist dispositions and P1–P12 are covered. No new blocking security defect was established. R1-SEC-01 is a Low nonblocking stale-comment issue, open at this head with an authorized correction planned before fresh round 2. Existing HIGH T-038 remains excluded, open and undowngraded. Follow-up B documentation/reconciliation, maintainer review, all eight tasks' In Review status and merge-dependent first-main/default-dispatch evidence remain untouched by this approval. + +## Coordinator publication and finding disposition + +The complete reviewer report above is preserved at its immutable reviewed source. The [paired canonical report](../code-reviews/2026-10-12-pr48-tools-followup-r1.md) is published alongside it; private `/tmp` evidence paths remain acquisition locations, not durable links. The coordinator read both full reports and independently verified R1-SEC-01. This publication commit replaces the stale sibling-cache contrast with the current explicit-install/all-cache-bin-omission comment. Actionlint and whitespace checks pass after that comment-only correction. This records the correction, not a reviewer certification of future source; fresh round 2 is still required. diff --git a/docs/analysis/reviews/security-reviews/2026-10-12-pr48-tools-followup-r2.md b/docs/analysis/reviews/security-reviews/2026-10-12-pr48-tools-followup-r2.md new file mode 100644 index 00000000..2ba5c763 --- /dev/null +++ b/docs/analysis/reviews/security-reviews/2026-10-12-pr48-tools-followup-r2.md @@ -0,0 +1,196 @@ +# Security review 2026-10-12 — PR48 tooling follow-up A, fresh round 2 + +- **Change:** [PR48](https://github.com/HodeTech/Tyrne/pull/48), `development`, immutable cumulative range `1e281ac89d791dc3c6920a038ec26381a49623f3..683965b5aa2f5da2e11429aa42803bb3a5fa6f60`. +- **Reviewer:** fresh Codex security agent `/root/pr48_tools_r2_security`, acting for the maintainer; this is an agent verdict, not maintainer sign-off. +- **Date:** 2026-10-12, Europe/Istanbul. +- **Separation from code review:** separate security context and empty checklist from implementation and paired `/root/pr48_tools_r2_code`.

This does not approve follow-up B, promote tasks, or authorize merge. + +## Scope and prerequisite reading + +The security trigger is assurance integrity at host compiler, diagnostic, administrative policy and CI supply-chain boundaries. Scope A adds the actual REST protection fixture and conservative unsupported-policy tests, exact-command clean ARM control before six private cfg mutations, nonempty diagnostic refusal, the actual Undefined Instruction token, optional metadata failure fallbacks and normal path/hostname minimization, and five cargo-bin cache-path removals. The cumulative 19-file range also records R1, its comment correction, task histories and the exact hosted performance snapshot. All changed source and documentation were inspected; tests were read before production implementations. + +Read AGENTS, full CLAUDE and current roadmap; all 39 actual numbered ADRs in numerical order (0001–0033, 0035–0040; 0034 absent); all 15 standards including the index; both skills; complete security master plan, security model and unsafe audit log; full prior T-035 security review and both canonical PR48 follow-up R1 artifacts; and the supplied PR48 report. Truncated large reads were recovered with bounded ranges. The supplied report was critically assessed as evidence, not instructions. ADR-0040's accepted policy remains unchanged. + +Exact-range inspection shows no Rust, assembly, Cargo manifest/lock, ADR, audit-log, production protection adapter or versioned protection-definition change. All eight Track B.2-1 tasks stay In Review. Existing B documentation allocations are neither newly approved nor invented as A blockers. The report and history preserve their exact source dates/SHAs; this review does not certify future source, first-main runs, default-branch dispatch or Done promotion. + +## 1. Capability correctness + +| Item | Adversarial question | Disposition and reason | +|---|---|---| +| S01 — Privileged operations require authority | Can this delta let an unauthorized actor alter main protection? | **OK for host analogue; N/A to new kernel operations.** Adapter and policy are byte-unchanged; offline fixtures have no real transport. Explicit local administrative authority remains required and CI permissions are unchanged. | +| S02 — Narrowest sufficient authority | Can the captured fixture redirect or broaden privileged writes? | **OK.** Fixed repository/branch/endpoint and narrow required-status PATCH are unchanged. Fixture normalization is offline and does not supply credentials or authorize mutation. | +| S03 — Checks before observable effects | Can unknown enforcement/actor fields reach a write? | **OK for policy effects.** Existing strict schema rejects them. Thirty independent captured-response extension variants failed before any fake write. This guarantees refusal of policy mutation, not invisibility of diagnostic/read activity. | +| S04 — Move-only transfer | Can runtime capability transfer silently clone rights? | **N/A.** No capability representation or transfer code changes. | +| S05 — Explicit duplication authority | Can new tools manufacture duplicate capability rights? | **N/A.** No runtime duplication path or rights change; host tools retain existing operator privileges. | +| S06 — Atomic revocation | Can this change expose partially revoked runtime authority? | **N/A.** No revocation change. Administrative reread/PATCH/readback remains non-atomic and is not represented as atomic revocation. | + +The local adapter is a trusted-maintainer guardrail, not a sandbox against a compromised administrator, host or executable. Its environment-based CI refusal does not prevent an administrator calling GitHub directly. The existing approving-review count 0 and disabled admin enforcement are preserved, not silently tightened or weakened. + +## 2. Trust boundaries + +| Item | Adversarial question | Disposition and reason | +|---|---|---| +| S07 — Validate userspace inputs before use | Can malformed input cross a newly weakened parser? | **N/A to kernel; OK for host analogue.** No syscall parser changes. Complete captured REST normalization equals the entire canonical policy; unknown extensions are still refused. | +| S08 — User pointers use validated mappings | Can an untrusted address become a privileged dereference? | **N/A.** No pointer, page mapping or copy-user change. Existing host API transport uses fixed argv and stdin JSON. | +| S09 — Range-check user lengths | Can unchecked lengths overrun a mapped buffer or partial evidence be mislabeled complete? | **N/A to memory; OK for host evidence.** No buffer consumer changes. Existing remote total/count/100-entry refusal controls and explicit valid/failed measurement counts remain. | +| S10 — Typed message parsing | Can policy-bearing fields be discarded as metadata, or unrelated errors count as intended rejection? | **OK.** Policy tests refuse unsupported fields; ARM requires a successful identical clean command before mutation, exit 101 and one of two exact whole-line diagnostics afterward. Empty and near-match diagnostics fail. | +| S11 — IPC grants no excess authority | Can a sender transfer rights it never held? | **N/A.** No IPC, capability-table or rights-transfer changes. | + +**Policy shape.** `tools/fixtures/main-protection-2026-10-12.json` is a dated complete captured protection-endpoint body, including URL metadata and original context ordering. It parses equal to the coordinator-supplied capture and normalizes with the separately versioned GraphQL rule to the full canonical definition, including six app-bound checks and non-status policy. This is a fixture/provenance check, not a fresh live drift attestation. Unsupported enforcement scope and dismissal/bypass actors carry policy and must not be indiscriminately stripped. Branch-summary `name`/`protection_url` do not establish protection-endpoint compatibility. The new tests correctly retain refusal even for empty-looking extensions. Future response changes can stop maintenance until reviewed adaptation; no availability guarantee or broad metadata allow-list is claimed. + +**ARM attribution.** `tools/test-ci-gates.sh:83–110` defines the clippy argv once, validates exactly six source anchors, requires the same command to pass in the unmodified private copy/private target, then changes only those six hello predicates. Build script and syscall shim remain unchanged. The negative must return 101 with the exact duplicate-panic or unsupported-unwind line; unrelated failures, status 0, tool errors and empty diagnostics fail. Both observed classes remain justified by Cargo all-target compilation ordering. The successful clean baseline closes the concrete pre-existing-error false-attribution route; it does not prove causal isolation against a hostile compiler or every nondeterministic external failure. + +**Smoke token.** `tools/smoke.sh:151` now matches `Undefined Instruction`, consistent with the producer spelling documented in the BSP checklist. Synthetic debug/release traces retain required success markers while injecting that fault, and fail. This is actual matcher coverage, not an actual Undefined Instruction guest mutation: the three real private guest controls omit EL0, omit completion and inject a release greeting. No exact SVC count, exhaustive exception classifier or adversarial EL0 claim is made. + +## 3. Memory safety + +| Item | Adversarial question | Disposition and reason | +|---|---|---| +| S12 — New unsafe satisfies policy | Can new unsafe escape SAFETY/audit review? | **N/A.** No production Rust/assembly or unsafe changes; host shell/Python does not require an invented unsafe entry. | +| S13 — Safety invariants hold for every caller | Can green tooling certify an unsound existing asm contract? | **Flagged — existing excluded HIGH T-038 remains open.** Input-only x2 versus kernel return clobber is unchanged; no new caller broadens it and this review does not endorse it. | +| S14 — No uninitialized memory exposed | Can partially initialized data reach a task or report? | **N/A to runtime; OK for metadata handling.** No buffer initialization changes; failed optional metadata is replaced by unknown, not retained partial stdout. | +| S15 — No use-after-free | Can changed ownership or cleanup destroy live source? | **N/A to raw pointers; OK for probe isolation.** Fresh temporary source/target and quoted cleanup are retained. Fixtures check source hashes and cleanup on success/refusal/copy failure. | +| S16 — No aliasing violations | Can a borrow now cross a context switch or race? | **N/A.** No reference, scheduler, synchronization or runtime ownership change. Private targets avoid shared build outputs. | + +The complete audit-log read reconciles applicability and historical amendments; it is not a fresh approval of every historical invariant. No unsafe approval/amendment is owed for this delta. Local/hosted compiler, Miri and smoke success cannot clear T-038's architecture assembly contract. + +## 4. Kernel-mode discipline + +| Item | Adversarial question | Disposition and reason | +|---|---|---| +| S17 — No ISR allocations | Can the new report path allocate in interrupt context? | **N/A.** Host reporting only; no ISR path change. | +| S18 — Bounded kernel loops | Can a new loop stall privileged guest execution? | **N/A.** Kernel loops unchanged. Finite samples, guest watchdogs and hosted job bounds remain; fallbacks add no retry loop. | +| S19 — Minimize critical sections | Can compiler/API waits hold a kernel lock? | **N/A.** No kernel lock, scheduler or IRQ-mask change. | +| S20 — No new hot-path panic | Can the intended panic-handler regression enter shipped source? | **N/A to runtime; OK for host separation.** Six predicates mutate only the disposable copy after the clean control. Production cfgs remain unchanged. | +| MP-1 — Typed allocation exhaustion | Can resource exhaustion newly panic the kernel? | **N/A.** No kernel allocator/quota/error path changes. Host disk/tool failures are not accepted as the intended ARM compiler diagnostic. | + +Optional metadata failure does not make missing measurement data successful: valid-sample thresholds and failed-through-tee controls remain intact. The additional clean clippy command is finite and passes locally and in downloaded hosted evidence; no quantitative runtime assurance beyond those observations is inferred. + +## 5. Cryptography + +| Item | Adversarial question | Disposition and reason | +|---|---|---| +| S21 — Reviewed primitives | Can a new homemade algorithm forge authority? | **N/A.** No crypto primitive/protocol is introduced. Source/digest references are provenance, not a new authentication scheme. | +| S22 — Keys absent from diagnostics | Can failed metadata expose secret-like output? | **OK for applicable diagnostic handling.** Stderr is suppressed and nonzero-command stdout discarded. Independent canaries on both streams remain absent from process output and report. No key management is added. | +| S23 — Constant-time comparison | Can a secret comparison leak timing? | **N/A.** Policy/diagnostic/source comparisons use public values; no cryptographic equality changes. | +| S24 — Acceptable randomness | Can predictable random data mint authority? | **N/A.** No key/token/randomness generator changes. Temporary paths use existing platform facilities. | +| S25 — Correct nonce/IV/salt handling | Can reuse undermine authentication? | **N/A.** No nonce, IV, salt or encryption state is introduced. | + +## 6. Secrets and logging + +| Item | Adversarial question | Disposition and reason | +|---|---|---| +| S26 — No secrets in diagnostic channels | Can normal metadata disclose unnecessary private paths/hostname or preserve failed output? | **OK within stated minimization.** `uname -srm` omits hostname; rustup's normal override explanation is stripped while its toolchain identifier remains. Four optional commands use unknown on failure and suppress stderr. No credential/environment dump is introduced. | +| S27 — Sensitive Debug redacts/absent | Can a changed formatter expose capability bits? | **N/A to Rust Debug; OK for host representation.** No sensitive Rust type changes. Normal report identity fields are minimized while source-state/reproducibility metadata remains. | + +`tools/perf-harness.sh:251–264` handles metadata failure independently of sampling. The seven methods cover missing/failing commands, partial/zero measurement failure, dirty/unknown Git state, overwrite refusal and Bash/tee propagation. Eight additional canary subcases test nonzero stdout and stderr together for all four optional commands, statuses 1/127. + +This is privacy minimization, not universal sanitization of arbitrary successful output. Custom toolchain names can contain operator-chosen identifiers; a compromised tool can emit arbitrary data. Existing archived reports remain historical. The unchanged hosted workflow separately captures raw toolchain output on its public disposable runner; this verdict does not claim every auxiliary artifact or historic report has been redacted. B owns its planned documentation reconciliation. + +## 7. Dependencies + +| Item | Adversarial question | Disposition and reason | +|---|---|---| +| S28 — Addition policy followed | Can unaudited dependency code silently enter the kernel? | **OK.** No crate/toolchain/action-pin addition or upgrade; Python is stdlib and shell uses existing tools. | +| S29 — Trust category understood | Can cache restore replace installed executables or be mistaken for fully trusted builds? | **OK for the scoped reduction.** Five bin paths are removed; registry/git/target caches remain. Explicit tool installation, OS/architecture identities and action pins remain unchanged. This is no hermetic-build or all-cache-poisoning guarantee. | +| S30 — cargo-vet decisions updated | Is a new crate left unaudited? | **N/A.** Cargo graph/lockfile unchanged; no new trust decision and no claim of executing cargo-vet/audit. | + +Workflow diff contains exactly five removed `~/.cargo/bin` paths plus the R1 comment correction. Cache keys/prefixes, other paths, triggers, permissions and commands remain unchanged. Coverage still explicitly installs pinned cargo-llvm-cov; toolchain installation remains before affected restores. Remaining registry/git/target inputs can still contain executable build artifacts and remain a trust boundary. No historical cache was deleted and no poisoning or cache-version experiment was performed. + +At `ci.yml:438–439`, the revised comment says tools are installed explicitly and all CI caches omit bin; this matches all cache path lists in both workflows. Searching the old sibling contrast finds no remaining workflow occurrence. Its indentation has no YAML semantic effect; actionlint passes. R1-SEC-01 is resolved without a runtime/policy change. + +## 8. Threat-model impact + +| Item | Adversarial question | Disposition and reason | +|---|---|---| +| S31 — Reconciled with security model | Can host assurance weaken runtime isolation or conceal policy drift? | **OK for scoped delta.** No runtime principal, capability, MMU/IPC/DMA boundary changes. Clean compiler control, exact fault token, conservative policy refusal, explicit unknown metadata and smaller bin-restore surface strengthen evidence within existing trust assumptions. | +| S32 — Model shift documented/tracked | Is a new trust promise silently introduced? | **OK.** ADR-0040 and policy are unchanged. Trusted host/compiler/workflow review and coordinated non-atomic administration remain assumptions; B reconciliation remains explicitly pending. | + +The supplied report's particular duplicate-job-name bypass is **not demonstrated** by this review. App ID identifies producer, not workflow contents; review of workflow content remains necessary. The adapter's duplicate-name refusal applies to evidence authorizing new check registration, not a theorem about GitHub merge enforcement. Neither conflation nor an unproven hosted bypass is accepted. No CODEOWNERS, reviewer-count, admin-enforcement or ruleset policy is silently changed. + +The existing final reread/readback cannot remove concurrent-administrator races; separate REST/GraphQL reads and narrow PATCH are not compare-and-swap. The dated capture cannot promise permanent drift absence. No live apply/export/check was run by this reviewer. Performance remains informational with no timing merge threshold. Schedule/default dispatch and first merged-main proof remain pending maintainer merge. + +## Findings and R1 reconciliation + +**New findings: zero.** No new Blocker, High, Medium or Low defect was established in the cumulative scope. + +**R1-SEC-01 — Low, resolved:** the stale sibling-cache contrast at R1 head 50ab is replaced at 683965b with accurate explicit-install/all-cache-bin-omission wording. Independently inspected the correction and cache inventory; actionlint and whitespace validation pass. The canonical R1 artifacts correctly preserve that head's historical open finding and append the coordinator correction rather than claiming reviewers approved future bytes. + +The existing HIGH T-038 is not counted as a newly waived minor or a resolved issue. B's allocated prose concerns remain pending and outside this approval. All eight tasks remain In Review; recording evidence and this security approval do not promote them. + +## Architectural principles P1–P12 + +| Principle | Adversarial question | Disposition and reason | +|---|---|---| +| P1 — No ambient authority | Does this create implicit runtime or CI admin power? | **OK.** No grants or permission widening; adapter authority unchanged. | +| P2 — Smallest defensible TCB | Does host reporting expand privileged kernel code? | **OK.** Host-only delta, no kernel TCB increase. | +| P3 — Services in userspace | Is a driver/service moved into the kernel? | **N/A.** No runtime placement change. | +| P4 — Checks at boundaries | Can a new unchecked input gain authority? | **OK for host analogue.** Unknown policy refuses before writes; runtime boundaries unchanged. | +| P5 — Rust-only kernel | Is unaudited assembly or another kernel language introduced? | **N/A to changed source.** Bash/Python are host tools; no unsafe broadening, T-038 stays HIGH. | +| P6 — HAL separation | Does architecture detail leak into kernel interfaces? | **N/A.** No HAL/kernel source change. | +| P7 — No proprietary blobs | Does the patch commit opaque guest code? | **OK.** Text fixture/report/scripts only, no proprietary blob. | +| P8 — Recorded decisions | Does a policy change bypass an ADR? | **OK.** Existing ADR-0040 implementation policy remains byte-unchanged. | +| P9 — English repository | Does new repository prose violate the language rule? | **OK for scoped delta.** New source/comments/history English; allocated B concerns not prematurely cleared. | +| P10 — Mermaid diagrams | Does the patch add another diagram format? | **N/A.** No new diagram. | +| P11 — Reproducibility | Is provenance weakened or toolchain silently changed? | **OK within limits.** Pins/lockfile unchanged; source state and normal identifier retained, absent metadata explicitly unknown. Host timing remains contextual. | +| P12 — No half-finished main | Is development evidence mislabeled completion? | **OK for scope.** All eight tasks remain In Review; B, maintainer decision and merge-dependent proof remain open. | + +## Independent execution and provenance + +Checks used a private archive of exact 683965b at `/var/folders/d2/k7c1fj3976g7_qq7113f66p00000gn/T/tyrne-pr48-security-r2._cpspwln/tree`; locator `/tmp/tyrne-pr48-security-r2-dir`.

No repository edit, checkout, commit, branch operation, API write, shared target or shared userland image was used. + +A read-only manifest Git shim provides only exact source HEAD, development label, hash-checked tracked status and the immutable NUL-delimited tracked inventory for archive consumers; all other Git commands fail. It does not mock compiler/Bash/Python behavior. This supplies absent archive metadata and is not a test of Git. First archive preparation encountered an unsupported Python `extractall(filter=...)` argument and stopped before extraction; it was retried with this trusted local archive. That preparation failure is not counted as validation. + +Local compiler: `rustc 1.94.0-nightly (86a49fd71 2026-01-14)`, native `aarch64-apple-darwin`, LLVM 21.1.8.

Revisited missing portions of truncated reads in smaller slices.

Read all changed documentation hunks, T-030 in full, the Phase B.2 preflight review and both T-037 security rounds, plus UNSAFE-2026-0033 and its amendments. ADR-0030/0031 explain the debug-console contract; ADR-0039 explains the matching-image build order; Accepted ADR-0040 authorizes this CI policy. No new ADR decision was silently selected. + +Independent execution here is the ten-case controlled guard matrix described below. The broader local suite is coordinator-reported evidence; hosted evidence was inspected in the coordinator-fetched logs, rather than fetched or re-executed by this reviewer. The hosted run covers `c716ae3`; `364b746` changes evidence documents only. + +### 1. Capability correctness + +| # | Standard item | Outcome and adversarial justification | +|---|---|---| +| 1 | Every privileged operation requires the right capability | **OK for delta.** Could release callers obtain console authority through an accidentally enabled debug interface? CI now requires decode(5) to reject and the dispatch test to return `BadSyscallNumber`; existing authority checks are unchanged. | +| 2 | Narrowest sufficient capability | **OK for delta.** No new grant, right, capability type or bypass is introduced; the debug-only path retains `DebugConsole`/`CONSOLE_WRITE`. | +| 3 | Checks precede side effects and failed checks leak no state | **OK for delta.** Release decode rejects before capability lookup, pointer translation or output; the release dispatcher test checks both the precise denial status and an empty console. | +| 4 | Capability transfer remains move-only | **N/A.** Neither transfer nor capability representation changes. | +| 5 | Duplication requires explicit authority | **N/A.** No duplication operation or caller changes. | +| 6 | Revocation is atomic with concurrent use | **N/A.** This compile/test enforcement changes no revocation or concurrency path. | + +The dispatch test grants a valid console capability, so rejection cannot accidentally pass merely because the capability is absent. Its empty user window does not make the status assertion vacuous: an exposed console path would return an address error rather than the required bad-syscall status. The separate decode test directly pins the release number table. + +### 2. Trust boundaries + +| # | Standard item | Outcome and adversarial justification | +|---|---|---| +| 7 | Validate all userspace input before use | **OK for delta.** No new runtime input reaches the kernel; raw syscall number 5 remains denied under release configuration, independently of supplied arguments. | +| 8 | Validate userspace pointers through mappings | **OK for delta.** No pointer consumer or mapping check changes; release denial occurs before the unchanged copy-user path. | +| 9 | Range-check buffer lengths | **OK for delta.** The import cfgs do not change length checks or test assertions; no larger range becomes accepted. | +| 10 | Parse messages into typed structures | **N/A.** No message wire format, decoder or parser changes. | +| 11 | IPC cannot grant more authority than caller holds | **N/A.** IPC and transfer behavior are untouched. | + +**Build/CI trust analysis.** The new boundary is source/configuration → release-test evidence. `check-release-tests.sh:10–15` requires the two fully qualified libtest success lines and a two-passed/zero-failed summary, closing the zero-match success hazard. Its `set -euo pipefail` prevents `tee` from masking Cargo failure. Tests cannot disappear, become ignored, be renamed, or gain a third passing matching test without failing the guard. Ordinary libtest output under the pinned toolchain is the intended interface; a format change fails closed. + +`test-ci-gates.sh:19–33,73–76` copies tracked current worktree files with NUL-delimited names, preserves executable modes, uses a fresh private `mktemp` tree and target directory, and removes only that quoted directory on exit. The profile is changed only inside this tree. `run_negative` requires both a nonzero exit and the matching guard diagnostic; unrelated Cargo compilation failure alone cannot pass the probe. The observed profile-flip exit is 1. Although the generic helper accepts any nonzero value with the diagnostic, that does not weaken this current path: the guard emits this diagnostic itself immediately before exit 1. + +The copied `rust-toolchain.toml` preserves the implicit Cargo pin; the normal workflow uses the matching explicit nightly. A private target directory prevents an old release test executable from satisfying the negative experiment. Tracked source and the compiler/build environment remain trusted: this is regression detection, not authentication of a malicious compiler, forged test output, hostile same-user process, or malicious repository code. The deliberate stub used by this review tests parsing/error propagation, not that broader trust premise. + +**Workflow token/cache/profile analysis.** No trigger, credential, permission, secret, action version or cache key is added or widened. Existing `contents: read`, immutable action pins and `persist-credentials: false` remain. No PR-controlled metadata is interpolated into the new shell commands. Existing Cargo caches are a build acceleration trust surface, not an authorization boundary; the new negative target is outside those caches. The workflow keeps existing required job names and adds blocking steps without `continue-on-error` on the new gates. + +The kernel job builds matching debug userland/kernel, matching release userland/kernel and release clippy, then immediately restores debug userland before debug `perf-bench` build and final lint (`ci.yml:166–179`). The BSP only checks image presence/change, not its profile; the explicit ordering is therefore load-bearing and correct. No concurrent job writes this job's workspace. Local simultaneous builds would still require caller coordination, an existing property not newly promised by these aliases. + +### 3. Memory safety + +| # | Standard item | Outcome and adversarial justification | +|---|---|---| +| 12 | New unsafe satisfies unsafe-policy | **N/A.** There is no new/modified unsafe operation, unsafe function, SAFETY comment or safety assumption in the delta. Test import cfgs need no audit entry/amendment. | +| 13 | SAFETY invariants hold for every caller | **Flagged — existing HIGH T-038, excluded.** Existing input-only `x2` in the userland console shim conflicts with kernel write-back; this review does not affirm that invariant. No affected caller, operand, safety reasoning or compilation boundary is changed here. | +| 14 | No uninitialized memory exposed | **OK for delta.** No storage, memory access, initialization, assembly output or runtime code changes. | +| 15 | No use-after-free; raw-pointer lifetimes valid | **OK for delta.** No ownership/lifetime, allocation, raw-pointer construction or dereference changes. | +| 16 | No aliasing violations | **OK for delta.** Cfg-scoping imports cannot introduce conflicting references; existing unsafe contracts are not newly certified. | + +**Unsafe verdict explicitly N/A to this delta.** Unlike T-037, which changed predicates enclosing existing unsafe sites and required a boundary amendment, T-030 changes only test imports and CI/configuration enforcement. UNSAFE-2026-0033 is relevant background, not a modified audit contract. No audit ID or amendment is warranted. The original `x2` claim remains excluded at HIGH severity under T-038. Passing clippy, host Miri, release builds or matching images does not certify SVC assembly soundness. + +### 4. Kernel-mode discipline + +| # | Standard item | Outcome and adversarial justification | +|---|---|---| +| 17 | No allocation in ISR context | **N/A.** No ISR or kernel allocation code changes. | +| 18 | Kernel loops bounded | **N/A.** No runtime loop changes; file copying/testing occurs on the host with finite tracked inputs. | +| 19 | Critical sections minimal and justified | **N/A.** No lock, IRQ mask, scheduling or critical section changes. | +| 20 | No new hot-path kernel panic | **OK for delta.** New failures are host script exit codes; production kernel panic/error behavior is unchanged. | +| 33 | Allocation failure produces a typed error (master-plan addition) | **N/A.** No kernel allocation/exhaustion path changes. Host `mktemp`, copy or Cargo failures propagate as command failures instead of inventing green test evidence. | + +CI takes additional build time and isolated disk space, but no user-controlled runtime work or kernel resource budget is expanded. Host workflow timing is not a performance-regression claim about the guest. + +### 5. Cryptography + +| # | Standard item | Outcome and adversarial justification | +|---|---|---| +| 21 | Primitives reviewed; no roll-your-own crypto | **N/A.** No cryptographic primitive or algorithm introduced. | +| 22 | Keys absent from logs/debug/display | **N/A.** No key material or key handling introduced. | +| 23 | Secret comparisons constant-time | **N/A.** Test names, summary text and Cargo profile metadata are public values, not secrets. | +| 24 | Randomness from an acceptable source | **N/A.** No kernel/security RNG changes; host `mktemp` is used for safe temporary-file creation rather than cryptographic authority. | +| 25 | Nonce/IV/salt use correct | **N/A.** No such operation changes. | + +### 6. Secrets and logging + +| # | Standard item | Outcome and adversarial justification | +|---|---|---| +| 26 | No secrets in logs, panics, prints or errors | **OK.** New output is Cargo/libtest diagnostics and fixed gate text, with no secret/token interpolation; temporary logs are removed on ordinary exit and error paths. | +| 27 | Sensitive Debug implementations redact | **N/A.** No Debug/Display implementation or sensitive type changes. | + +Could release testing itself enable production console output? The tests execute host fakes; only the private negative tree enables debug assertions. The production release profile receives a comment and retains its existing false default. Existing kernel diagnostic output is not claimed to disappear: the scoped contract removes the user-facing `console_write` syscall from the release decode table. + +### 7. Dependencies + +| # | Standard item | Outcome and adversarial justification | +|---|---|---| +| 28 | New dependencies evaluated per policy | **N/A.** No crate, binary dependency, action or lockfile addition. The script uses existing host shell/Cargo utilities. | +| 29 | Dependency trust category understood | **OK for delta.** New orchestration executes only during host verification; it adds no code to the privileged runtime TCB or userland artifact. | +| 30 | cargo-vet decisions updated | **N/A.** Dependency graph and audit decisions are unchanged; dormant external-dependency gates are not represented as newly active. | + +### 8. Threat-model impact + +| # | Standard item | Outcome and adversarial justification | +|---|---|---| +| 31 | Reconciled against security-model.md | **OK.** The change improves detection of developer error that would expose a debug syscall to malicious userspace; capability, memory, fault and DMA boundaries remain unchanged. | +| 32 | Model shift documented or tracked | **N/A — no model shift.** No new principal, privilege, runtime communication path or defended attacker class is introduced. Existing T-034 runtime smoke and T-065 explicit-feature work retain ownership. | + +The gate is meaningful but bounded: it exercises the host-compiled release syscall contract plus cross-compilation/lint of the bare-metal image; it is not proof of release EL0 execution. A target-specific future gate regression would need the T-034 runtime test, and a deliberate source author can change tests and guard together. Neither limitation is obscured by the current docs. + +### Architectural principles P1–P12 + +| Principle | Result | +|---|---| +| P1 — No ambient authority | **OK:** release syscall absence is enforced without granting new runtime authority. | +| P2 — Smallest defensible TCB | **OK:** only host verification grows; production Rust unchanged. | +| P3 — Drivers in userspace | **N/A:** no subsystem placement or driver change. | +| P4 — Checks at trust boundaries | **OK:** unchanged runtime checks are complemented by fail-closed release evidence. | +| P5 — Rust-only kernel / audited assembly | **OK for delta:** shell is host tooling; no assembly or unsafe change approved. | +| P6 — HAL separation | **OK:** three cfg-scoped test imports introduce no hardware dependence into kernel runtime. | +| P7 — No proprietary binary blobs | **OK:** userland remains rebuilt from source; no binary is committed. | +| P8 — ADR governance | **OK:** ADR-0030/0031/0039 and Accepted ADR-0040 govern the work; standards follow that existing policy. | +| P9 — English artifacts | **OK:** changed code, comments, diagnostics and docs are English. | +| P10 — Mermaid diagrams | **N/A:** no diagram introduced. | +| P11 — Reproducibility | **OK for delta:** pinned toolchain/lockfile preserved, isolated target used for negative probe, matching image order explicit; this is not a bit-for-bit reproducibility audit. | +| P12 — Complete declared scope | **OK:** T-030 implementation gates are concrete; remaining review lifecycle, T-034 runtime coverage and T-065 mechanism change are explicitly separated. | + +### Independent adversarial verification + +Executed the actual guard in a private fixture tree with a controlled Cargo stub, `/bin/bash`, repository and temporary paths containing spaces. Results are saved in `/tmp/tyrne-b21-t030-round1-security-probes.json`. + +| Case | Expected / observed exit | +|---|---| +| Both exact success lines and two-pass summary | 0 / 0 | +| Both tests vanished, zero-pass summary | 1 / 1 | +| Missing ABI success line | 1 / 1 | +| Missing dispatch success line | 1 / 1 | +| Renamed ABI module despite successful summary | 1 / 1 | +| ABI line reports ignored | 1 / 1 | +| Correct two names but three-pass summary | 1 / 1 | +| Correct names but failed summary | 1 / 1 | +| Cargo prints valid green transcript then returns 101 | 101 / 101 | +| Unexpected `--release` argument to the no-argument guard | 2 / 2 | + +Every created gate log was removed after success and failure. The argument-rejection case exits before log creation. These probes independently establish the parser and pipeline's fail-closed behavior. They do not substitute for real Cargo execution; that complementary evidence is present in the coordinator's local execution and the inspected hosted logs. + +### Hosted/local evidence and limits + +The inspected hosted logs for [run 38179424325](https://github.com/HodeTech/Tyrne/actions/runs/38179424325), at `c716ae3`, show release totals **249 kernel + 46 HAL + 58 test-HAL + 3 doc = 356**, with two existing ignored HAL doctests; both exact named narrow tests and a two-pass summary; and the isolated profile flip rejected with **exit 1 and the guard diagnostic**. The kernel log shows **117-byte debug → 69-byte release → restored 117-byte debug**, then final debug perf build/lint. Coordinator-reported run metadata records all five jobs successful. The 13-second hosted release step wall time is build/test overhead, not guest performance. + +Coordinator local evidence reports fmt, ShellCheck/actionlint, host/debug/release/perf/userland clippy, debug/release/perf builds, 366 debug and 356 release host tests, Miri 366 with zero UB failures and existing warnings, real narrow guard/profile-flip rejection, seven controlled guard cases and 59 stubbed QEMU fixtures. This reviewer did not repeat that full suite because the independent negative matrix addressed the novel failure concern. The reported restored debug SHA is `05816ccb9be5caea862dbe3e0fc45fc2068ff06cd049f2dda3459492d0ef7d88`; no shared image was written by this review. + +No runtime QEMU, hardware, target-specific syscall execution, cryptographic, SMP or broad kernel-soundness certification is made. T-038's known HIGH `x2` clobber defect remains excluded and unmitigated by these gates. Release runtime verification belongs to T-034. Hosted evidence is pre-merge development evidence, not a first-main/post-merge result. + +### Findings, checklist completion and verdict + +**No newly introduced security defect found.** All eight axes, 32 standard items, the master-plan allocation item, adversarial CI trust/failure cases and P1–P12 have explicit dispositions. The unchanged HIGH T-038 issue is retained in the memory-safety checklist without downgrading or implicitly approving it. + +**Approve Round 1 for `8437158..364b746`.** No source correction is requested. Publish this report with the paired code-review cross-reference/index and accurate security-review trailer as the coordinating follow-up, then complete the separate fresh Round 2. No task is promoted to Done and no merge is authorized by this verdict. + +## Round 2 security review + +**Approve the T-030 delta in `8437158..5cd9ee8`. No new actionable security finding.** The existing HIGH T-038 assembly-contract defect remains expressly excluded. This review does not promote a task to Done or replace final maintainer PR review. + +- **Change:** approved Track B.2-1 step 4, `development`, `8437158..5cd9ee8a01ac523e48146e2224284b871e3619ab`. +- **Reviewer:** fresh independent Codex security agent `/root/b21_step4_round2_security`, acting on behalf of @cemililik. +- **Date:** 2026-10-12, Europe/Istanbul. +- **Requested configuration:** `gpt-6-astra`, high reasoning, `fork_turns=none`. This is coordinator-supplied orchestration provenance, not independent runtime model-identity attestation. +- **Separation from code review:** dedicated fresh security context and empty checklist, separate from implementation and the paired Round 2 code reviewer. This agent did not perform the paired code review. Earlier canonical reviews were read as historical evidence, not adopted as the verdict. +- **Unsafe audit cross-reference:** N/A for the delta. No unsafe site, enclosing production cfg, safety argument or caller changes. UNSAFE-2026-0033 and its amendments were read as relevant background; its existing x2 claim is excluded under T-038. +- **Procedure:** `perform-security-review` and `conduct-review`, security standard, complete security master plan and security model; all eight axes performed sequentially. The standard has **32 items**. The master plan adds allocation-exhaustion handling, yielding **33 total dispositions** below; the extra item is explicitly labeled MP-1, not presented as a 33rd standard checkbox. +- **Recording boundary:** report and evidence files under `/tmp` only. No repository/GitHub edit, commit, branch mutation, shared image/kernel ELF write or external message. Coordinator owns canonical publication, index/cross-reference and truthful security-review trailer. Tasks remain In Review; final human PR review is pending. + +### Scope, reading and evidence provenance + +The 18-file range comprises implementation `b8ad56f`, standards reconciliation `c716ae3`, hosted evidence `364b746`, and Round 1 reports/index/task/current recording `5cd9ee8`. Executable changes are the release build/run aliases, release host tests and named-test guard, private profile-flip rejection, release cross-build/clippy, debug perf-bench build/clippy with matching image restoration, and three test-only imports scoped with `cfg(debug_assertions)`. The manifest adds a comment rather than changing the release profile. No production syscall mechanism changes. + +Mandatory baseline read: AGENTS, full CLAUDE, full current roadmap including historical banners, all 39 numbered ADR files in numerical order (0001–0033 and 0035–0040; 0034 has no file), all 15 files in `docs/standards/` including README, skill index, both applicable review skills, full security master plan and full security model. Truncated reads were recovered in bounded slices. Reading this corpus is not a fresh audit of every unchanged subsystem. + +Task intent and the actual release-only ABI/dispatch tests were read before the implementation. The focused source pass covered the guard/harness in full, Cargo configuration/manifests/toolchain, complete workflow, build-userland helper and BSP image build checks, syscall decode/dispatch entry and console validation, release test fixtures, relevant userland/BSP x2 operands, all executable and changed documentation hunks, task/index sequencing, prior preflight, both T-037 security rounds and both canonical T-030 Round 1 artifacts. The Round 1 recording accurately preserves its reviewed range and pending Round 2 state; `5cd9ee8` records a real separate security-review trailer without retroactively claiming one on implementation. + +Independent Git-object comparisons confirm the complete ABI file, userland shim, BSP syscall file, unsafe log, lockfile and toolchain are byte-identical across the review range. Dispatcher bytes before `mod tests` are identical. Its only Rust delta is moving `CONSOLE_WRITE_CHUNK`, `MappingFlags` and `FakeUserMem` imports behind the same debug-assertions predicate used by their test callers. No changed unsafe audit is required. + +Independent execution here consists of the real release guard, real isolated release profile-flip probe, 13 controlled guard cases, and three controlled probe/isolation cases described below. Parent's broad local suite and fetched hosted data remain explicitly attributed. This agent did not independently fetch GitHub metadata or rerun hosted jobs. + +### 1. Capability correctness + +| Standard item | Outcome and adversarial justification | +|---|---| +| S01 — Every introduced privileged operation requires a capability | **OK for delta.** Could release userspace gain console access when debug assertions drift? The new gate detects disappearance of the tests that enforce number-5 denial; production authority is unchanged. No new privileged operation is introduced. | +| S02 — Narrowest sufficient capability | **OK for delta.** Could the changes broaden a grant? No cap kind, right or lookup changes; the debug console still requires DebugConsole plus CONSOLE_WRITE. | +| S03 — Capability checks precede effects; failed checks leak no state | **OK for delta.** Could a release call emit before rejection? Decode returns None before capability lookup or pointer access; the unchanged dispatch test checks BadSyscallNumber and an empty console capture. | +| S04 — Transfer move-only, no accidental cloning | **N/A.** No capability transfer, representation or ownership operation changes. | +| S05 — Duplication requires explicit authority | **N/A.** No duplication operation or authority change exists in this delta. | +| S06 — Revocation atomic, no half-applied state | **N/A.** Build/test enforcement changes neither revocation nor concurrency. | + +The dispatcher regression holds a valid console capability and names raw syscall 5. Its empty user window does not make the test vacuous: entering the console handler would produce a range error rather than the asserted BadSyscallNumber. The ABI test separately asserts decode(5) is None. These are meaningful existing behavior tests; the new wrapper verifies they actually ran. + +### 2. Trust boundaries + +| Standard item | Outcome and adversarial justification | +|---|---| +| S07 — Validate userspace inputs before kernel use | **OK for delta.** Could arbitrary syscall arguments bypass the profile contract? The unchanged decoder rejects the number before reading argument-dependent resources; no new runtime input path is added. | +| S08 — User pointers only through validated mappings | **OK for delta.** Could cfg-scoped imports bypass mapping validation? No pointer consumer or translation code changes. Release rejection precedes the unchanged user-copy path. | +| S09 — Range-check user buffer lengths | **OK for delta.** Could a larger range become accepted? Pointer/length handling is byte-preserved in production; test import scoping does not alter range checks. | +| S10 — Typed parsing of userspace message contents | **N/A.** No message format, decoder or parser changes. | +| S11 — IPC grants no excess/untransferred authority | **N/A.** No IPC authority or transfer changes. | + +**Source/configuration to CI evidence is the changed trust boundary.** `tools/check-release-tests.sh` selects one kernel library binary and two filters. It requires both fully qualified exact successful test lines and a two-passed/zero-failed summary. Zero tests, missing/renamed/ignored required tests, duplicate evidence for one required test, and an additional passing matching test fail. A third matching **ignored** test alongside the two required passes is accepted; this does not invalidate execution of those two tests. The report does not claim all third matching tests are rejected. + +`set -euo pipefail` preserves Cargo failure through tee: independently, exact green text followed by Cargo exit 101 still exits 101. A pinned libtest output-format change would fail closed. This is regression checking over trusted source/build tools, not authenticity checking against a malicious compiler, forged Cargo stdout or a repository author who changes both implementation and its tests. + +`test-ci-gates.sh --release` makes its profile mutation only after copying tracked current files into a private mktemp tree, using NUL-separated names and preserved script modes. It assigns a separate Cargo target directory, preserves the pin/configuration, and requires both a nonzero guard status and the expected diagnostic. An unrelated compiler failure is rejected as insufficient evidence; an unexpectedly successful mutated gate is also rejected. Independent controlled execution verified the precise single insertion beneath `[profile.release]`, exact Cargo argument vector, copied working directory, sibling private target, absence of .git/untracked sentinel, unchanged source manifest and cleanup. Real execution then confirmed this logic rejects the actual profile flip. + +**Workflow authority and profile handling.** No new secret, environment-derived shell interpolation, permission widening, action version, trigger or cache-key change occurs. Existing read-only contents token, nonpersisted checkout credentials and SHA-pinned actions remain. Added steps are blocking inside existing required job names. Private negative compilation cannot reuse the normal target tree. Hosted job workspaces isolate sibling jobs; this change does not claim to make simultaneous local builds sharing hello.bin safe. + +The kernel job builds release userland before release kernel build/clippy, then immediately restores debug userland before debug perf build/lint. The BSP checks image existence and changes, not image profile, making this ordering substantive. Cargo feature/profile flags are before the clippy delimiter. Supplied hosted logs corroborate 117-byte debug → 69-byte release → 117-byte debug restoration. These are compilation gates; T-034 owns release guest execution. + +### 3. Memory safety + +| Standard item | Outcome and adversarial justification | +|---|---| +| S12 — New unsafe satisfies unsafe-policy | **N/A.** No unsafe operation, enclosing production cfg or safety-reasoning change exists; test imports do not require an audit amendment. | +| S13 — Safety invariants hold for every call site | **Flagged — existing HIGH T-038, expressly excluded.** Could a valid caller assume x2 survives? The unchanged shim declares input-only x2 while the kernel overwrites saved x2. No operand/caller/compilation boundary is changed here; this approval does not affirm that existing invariant. | +| S14 — No uninitialized memory exposed | **OK for delta.** No buffer initialization, assembly output or runtime memory-access change can newly expose bytes. | +| S15 — No use-after-free; pointer lifetimes justified | **OK for delta.** No allocation, raw-pointer construction, lifetime or ownership changes are introduced. | +| S16 — No aliasing violations | **OK for delta.** Import cfgs introduce no reference or mutation; existing unsafe contracts are not newly certified. | + +T-038 remains HIGH at `userland/tyrne-user/src/lib.rs:107` versus `bsp-qemu-virt/src/syscall.rs:224`. Read-only source inspection confirms the input-only/write-back mismatch remains; Git-object comparison confirms both files are unchanged. Host Miri, successful builds, host regression tests or an observed boot cannot downgrade or prove away this assembly contract defect. T-030's approval is restricted to the enforcement delta, not whole-kernel soundness. Unlike T-037, this change narrows no predicate surrounding an unsafe site and needs no corresponding UNSAFE-2026-0033 amendment. + +### 4. Kernel-mode discipline + +| Item | Outcome and adversarial justification | +|---|---| +| S17 — No ISR allocation | **N/A.** No interrupt handler or kernel allocation path changes. | +| S18 — Kernel loops bounded with termination | **N/A.** No kernel loop changes; finite tracked-file copying is host tooling, not a new attacker-driven kernel loop. | +| S19 — Critical sections minimized | **N/A.** No scheduler state, synchronization or IRQ-masked region changes. | +| S20 — No new hot-path kernel panic | **OK for delta.** New failures are host command exits; the production panic/error behavior is untouched. | +| MP-1 — Typed allocation-exhaustion error (master-plan extra, not a standard checkbox) | **N/A.** No kernel allocation or exhaustion handling changes. Host temp/copy/build failures cannot satisfy the intended positive/negative evidence contracts merely by failing. | + +The new jobs consume host compilation time/disk; they do not enlarge kernel resource limits. Guest performance is not inferred from CI step wall time. Existing runtime loop/critical-section debt remains outside this scoped delta. + +### 5. Cryptography + +| Standard item | Outcome and adversarial justification | +|---|---| +| S21 — Reviewed primitives; no homemade crypto | **N/A.** No primitive, algorithm or protocol is added. | +| S22 — Keys absent from logs, errors and Debug | **N/A.** No key material or key handling is introduced. | +| S23 — Constant-time comparisons where needed | **N/A.** Test names and profile metadata are public; no secret-dependent comparison changes. | +| S24 — Acceptable randomness source | **N/A.** No security RNG changes. Host mktemp provides exclusive temporary-file creation, not cryptographic capability generation. | +| S25 — Correct nonce/IV/salt handling | **N/A.** No nonce, IV or salt operation changes. | + +### 6. Secrets and logging + +| Standard item | Outcome and adversarial justification | +|---|---| +| S26 — No secrets in diagnostic channels | **OK.** Could the new logs reveal capability bits or credentials? New output is fixed gate text and ordinary test/build diagnostics; no secret argument is added. Ordinary success/error cleanup was observed. | +| S27 — Sensitive Debug impls redact or are absent | **N/A.** No formatting implementation or sensitive type changes. | + +The profile flip affects only the copied tree. The real release profile still uses the false default; no production console output is enabled by the probe. The contract concerns the user-facing syscall's presence, not removal of every kernel diagnostic. No signal/kill cleanup guarantee is asserted by this review. + +### 7. Dependencies + +| Standard item | Outcome and adversarial justification | +|---|---| +| S28 — New dependencies evaluated under policy | **N/A.** No crate, action, binary dependency or lockfile addition/upgrade occurs. Existing shell/Cargo utilities implement the new host checks. | +| S29 — Dependency trust category understood | **OK for delta.** Could build tooling become privileged runtime code? New shell orchestration remains host-only; no additional code is linked into the kernel. | +| S30 — cargo-vet trust decisions updated | **N/A.** Dependency graph/trust decisions are unchanged; no new audit decision is necessary or claimed. | + +Pinned toolchain and lockfile are byte-preserved. There is no proprietary blob addition. Userland remains source-built under ADR-0039; this review did not write the shared image. + +### 8. Threat-model impact + +| Standard item | Outcome and adversarial justification | +|---|---| +| S31 — Reconciled with security-model.md | **OK.** Could a developer configuration error expose a debug syscall to hostile userspace? The new gate detects the disappearing-test failure mode. Runtime capability, memory, fault, DMA and boot trust boundaries remain unchanged. | +| S32 — Model changes updated or follow-up linked | **N/A — no model shift.** No new principal, authority, communication path or attacker class is introduced. T-034 retains runtime smoke and T-065 the explicit debug feature; this gate claims neither. | + +Accepted ADR-0031 governs the capability-plus-debug contract, ADR-0039 the explicit image build, and ADR-0040 the reviewed development sequence and CI scope. Standards changes implement those decisions and do not select a new policy. The threat model's aspirational whole-system guarantees are not treated as proof that all existing implementation debt is resolved. A host release test cannot establish target-specific SVC execution; a future target-specific regression requires complementary runtime evidence. + +### Architectural principles P1–P12 + +| Principle | Disposition | +|---|---| +| P1 — No ambient authority | **OK:** release denial is enforced; no new runtime privilege is granted. | +| P2 — Smallest defensible TCB | **OK:** production code is unchanged; added shell runs only on host verification. | +| P3 — Drivers in userspace | **N/A:** no driver or subsystem placement change. | +| P4 — Checks at every trust boundary | **OK for delta:** existing capability/mapping checks are preserved; CI evidence now fails closed. | +| P5 — Rust kernel, audited unsafe | **OK for delta:** shell is tooling; no new unsafe approval or assembly-soundness claim. | +| P6 — HAL separation | **OK:** cfg-scoped test imports add no hardware dependency to production kernel code. | +| P7 — No proprietary blobs | **OK:** no binary addition; matching userland is built from source. | +| P8 — ADR decisions | **OK:** Accepted ADR-0040 precedes downstream standards; ADR-0031/0039 contracts are preserved. | +| P9 — English repository artifacts | **OK:** changed source, diagnostics, documentation and review artifacts are English. | +| P10 — Mermaid diagrams | **N/A:** no diagram addition. | +| P11 — Reproducibility | **OK for delta:** pin/lockfile unchanged, matching image sequence explicit, probe target private. This is not a bit-for-bit reproducibility audit. | +| P12 — Complete declared scope | **OK:** concrete T-030 gates and negative checks are present; later runtime work and final human review remain explicitly pending. | + +### Independent verification + +Executed on `aarch64-apple-darwin`, Rust `1.94.0-nightly (86a49fd71 2026-01-14)`, LLVM 21.1.8, selected by `nightly-2026-01-15`; `/bin/bash` 3.2.57.

Kernel entries show the 117 → 69 → 117-byte image order, release kernel build/clippy and final debug perf build/clippy. These are independently inspected supplied logs, not independently fetched/re-executed hosted checks.

I did not fetch or inspect that later run's logs. The earlier inspected logs establish the executable behavior; the later metadata is parent-supplied exact-HEAD evidence. + +Broader local implementation results are parent/task-record evidence: fmt, host/debug/release/perf/userland clippy, debug/release/perf builds, **366 debug / 356 release host passes**, Miri **366** with no UB failure and existing warnings, 59 QEMU argument fixtures and restored debug image SHA `05816ccb9be5caea862dbe3e0fc45fc2068ff06cd049f2dda3459492d0ef7d88`. I did not repeat that entire suite. The task's local 1.49 s and hosted 13 s release timings concern build/test overhead, not guest performance. + +Limits: no full unchanged dispatcher/kernel audit, broad unsafe-log reconciliation, full-suite Miri/stable rerun, additional bare-metal/profile build, actual QEMU/EL0 or hardware/SMP execution, bit-identical build comparison, cryptographic review, hostile termination stress, live protection audit or independent hosted fetch. No current execution result settles T-038. No first-main, post-merge or release-runtime coverage is claimed. + +### Findings, completion and verdict + +**No new security finding and no requested source correction.** The 32 standard checkbox items plus the one master-plan allocation item, all eight axes and P1–P12 are explicitly disposed.

Bounded reads recovered truncated policy portions. Read T-032 and the negative-probe harness before examining the source diff; then all executable changes, complete MMU implementation/helper, the ten exception functions and callers, Cargo aliases/toolchain, relevant CI changes, audit entry/history, capability unmap and its FakeMmu regression. Consulted the preflight review and prior T-037/T-030 security results and exclusions. This context reading is not a fresh whole-tree security certification. + +The only runtime expression change replaces the infallible zero-frame construction/unwrap in `QemuVirtMmu::unmap` with an existing typed root value as the helper's ignored third argument. Other Rust changes are lint attributes/comments. No syscall body, userland shim, capability policy, fatal exception policy, assembly, dependency, toolchain or architecture decision changes. Git-object comparison confirms both syscall/shim files, Cargo.lock and toolchain pin are byte-preserved. + +### 1. Capability correctness + +| Item | Disposition, adversarial question and justification | +|---|---| +| S01 — Every introduced privileged operation requires a capability | **OK for delta.** Can a caller unmap without authority because the root is passed twice? No operation or entry point is introduced; `cap_unmap` still resolves the capability and live arena object before MMU mutation. | +| S02 — Narrowest sufficient capability | **OK for delta.** Does the replacement root grant a broader right? It is a copied physical-frame address, not a capability or new grant; the existing address-space authorization model is unchanged. | +| S03 — Checks precede effects; failures leak no state | **OK for delta.** Can the new argument cause a descriptor write before authorization? The unchanged capability/arena checks precede MMU entry, and no new write exists. | +| S04 — Move-only capability transfer | **N/A.** Could this copy transferable authority? No capability representation or transfer changes; PhysFrame is an address value, not an authority token. | +| S05 — Explicit duplication authority | **N/A.** Could a new duplicate bypass authority? No capability duplication path is added or changed. | +| S06 — Atomic revocation | **N/A.** Could revocation become partially applied? No revocation or concurrency operation changes. | + +The pre-existing v1 address-space capability model is kind-based; this review does not invent per-operation MAP/UNMAP rights or expand the five-syscall set. Demo endpoint caps stay in trusted kernel task tables; the default EL0 task receives its console cap, not those endpoint caps. The benchmark EL0 table remains empty. + +### 2. Trust boundaries + +| Item | Disposition, adversarial question and justification | +|---|---| +| S07 — Validate userspace input before use | **OK for delta.** Can hostile syscall arguments enter an newly exempted function? Syscall code has no panic-family allow; the new exceptions attach to existing boot/demo/benchmark or fatal functions, with unchanged routing. | +| S08 — Userspace pointers only through validated mappings | **OK for delta.** Can the dummy root become a user-pointer dereference? The ignored parameter is never dereferenced on unmap; existing mapping/copy-user consumers are unchanged. | +| S09 — Range-check user lengths | **OK for delta.** Can a longer buffer become accepted? No buffer length, user window or translation validation changes. | +| S10 — Typed userspace message parsing | **N/A.** Could malformed bytes exploit a new parser? No wire format/parser is added or modified. | +| S11 — IPC grants only held/explicitly transferred authority | **OK for delta.** Can allowed demo panics hide an authority-transfer change? The demo and benchmark bodies/cap grants are unchanged; their IPC calls retain `None` transfers and statically provisioned rights. | + +The changed verification boundary is source-to-Clippy evidence. Both new modes append a non-test root function outside exception scopes. `black_box(None::).unwrap()` prevents the test from depending merely on a trivially known-None warning. The actual exact aliases are `cargo host-clippy` and `cargo kernel-clippy`; private copied Cargo configuration and toolchain preserve their target and `-D warnings` behavior. + +The harness requires both nonzero status and `clippy::unwrap_used`, rejecting unrelated failures or unexpected success. It copies tracked current files via NUL-delimited names, preserves script modes, uses mktemp isolation and a separate CARGO_TARGET_DIR, and deletes its quoted private root on normal exit/error. BSP builds source-derived userland only inside that copy before linting, preventing a missing shared image from masquerading as the intended lint rejection. Independent execution observed cleanup for both real modes. The supplied controlled fixtures additionally cover unrelated failure, unexpected green, exact argv, private target/image and CLI errors. This is a regression guard over trusted source/build tools; it does not authenticate deliberately forged compiler output or a malicious contributor who edits the gate and code together. + +Workflow additions are fixed command strings inside existing jobs. No trigger, action pin, permission, secret, credential persistence or cache change appears. Normal build/lint gates precede the negative probes; negative failure is evidence of rejection, not red production CI. Private targets avoid contaminating ordinary cached outputs. + +### 3. Memory safety + +| Item | Disposition, adversarial question and justification | +|---|---| +| S12 — Unsafe policy compliance | **OK for changed reasoning.** Does the new operand broaden unsafe or lack a record? Adjacent SAFETY explains why pa is unused and why an allow was rejected; the dated 0025 amendment names actual implementation SHA c3f32c8. Explicit approval follows. | +| S13 — Safety invariants hold for every caller | **OK for MMU delta; flagged existing HIGH T-038, excluded.** Can unmap consume pa on an error or success path? All three intermediate calls receive literal true; all exits and the entire true leaf arm ignore pa. Existing unrelated x2 input-only/write-back mismatch remains HIGH and is not approved. | +| S14 — No uninitialized memory exposed | **OK for delta.** Can the substituted frame introduce garbage into a descriptor or return? No: pa is unused; the returned frame still comes from the existing L3 descriptor. No initialization changes. | +| S15 — No use-after-free; raw-pointer lifetimes justified | **OK for delta.** Can reusing root free or extend a frame lifetime? PhysFrame is copied by value; no allocation/free, owner, pointer computation or lifetime changes. Existing exclusive valid-table lifetime obligations remain. | +| S16 — No aliasing violations | **OK for delta.** Does passing root twice create two mutable references? Both arguments are value copies, not references; descriptor access, caller's mutable address-space borrow and table ownership are unchanged. | + +**Explicit unsafe approval:** Reviewed `unsafe` in `bsp-qemu-virt/src/mmu.rs:307–333`, including the changed SAFETY comment and `walk_and_install_leaf` call at :319–328; I agree with and approve the changed SAFETY reasoning under UNSAFE-2026-0025. The call passes literal `true` for unmap. The helper reaches L3 through the unchanged root and VA, returns typed errors for missing/intermediate block mappings, reads the existing leaf, masks its PA, clears its slot and returns that leaf frame. Its `pa` parameter is used only in the false/map arm. Reusing already-valid `as_.root` as this ignored argument is sound and behavior-preserving under the existing table-validity/ownership/lifetime contracts. It introduces no new raw pointer or dereference and is preferable to weakening this non-init path with an unwrap allowance. + +The root argument, flags, null frame provider, descriptor accesses and caller flush obligation are identical. `cap_unmap` still flushes the returned token before returning the frame. Alignment and index bounds remain unchanged; a copied PhysFrame does not itself create ownership or authorize mapping. The change does not fix or worsen pre-existing caller-contract debt. + +Independent byte comparison removed the one new 1,502-byte amendment from the reviewed unsafe log and recovered the baseline log exactly: original entry and all historical amendments are preserved. The amendment accurately leaves actual review recording pending; coordinator should append this real verdict without rewriting that history. + +**Limits:** default smoke exercises boot/map, not this BSP unmap branch. FakeMmu unmap/rollback tests verify kernel-layer behavior and TLB-token discharge, not physical BSP table walking. No new runtime unmap coverage is claimed. Original 0025 SMP-forward-compatibility language is expressly not endorsed; T-069 retains that work. No full table-walker/SMP/architecture recertification follows from this narrow equivalence proof. + +**Existing HIGH retained:** `userland/tyrne-user/src/lib.rs:107` declares x2 input-only while `bsp-qemu-virt/src/syscall.rs:224` overwrites it on return. Both files are unchanged. T-038 remains its owner; host Miri, clean builds and successful boot neither downgrade it nor establish assembly soundness. + +### 4. Kernel-mode discipline + +| Item | Disposition, adversarial question and justification | +|---|---| +| S17 — No ISR allocation | **OK for delta.** Can the IRQ allowance enable a new allocation? IRQ body is unchanged; the annotation permits only existing panic behavior, with no new allocation path. | +| S18 — Bounded loops | **OK for delta.** Can attacker input create a new unbounded loop? No loop changes; pre-existing idle/demo/perf parking semantics are preserved and not newly certified as bounded. | +| S19 — Minimal critical sections | **OK for delta.** Does lint repair hold scheduler state longer? No lock, IRQ mask, borrow scope or context-switch sequence changes. | +| S20 — No new hot-path panic | **OK.** Can the guard conceal a new hostile-input panic? No panic/expect is added to runtime; the sole unwrap is removed. Exactly ten reasoned function exceptions, no HAL/syscall/MMU family allow. Assertions remain outside these lints. | +| MP-1 — Allocation exhaustion returns a typed error | **OK for delta.** Can malicious allocation exhaustion reach a new expect? No new allocation/error conversion occurs. Existing one-shot trusted setup expects remain scoped; MMU missing/allocation failures preserve typed errors. | + +#### Exception inventory + +| Function | Allowed lints | Classification and boundary | +|---|---|---| +| main::kernel_main_high (:996) | expect, panic | One-shot trusted boot; static image, fixed capacities and object setup precede scheduler start. | +| main::idle_entry (:522) | expect | Trusted scheduler invariant; yield runs only after start and its NoCurrentTask would indicate broken BSP state. | +| main::task_a (:674) | expect, panic | Trusted single-round demo; static endpoint/capability setup and fixed reply protocol. | +| main::task_b (:568) | expect, panic | Trusted single-round demo; matching static receive/reply protocol. | +| perf_bench::run (:147) | expect, panic | One-shot measurement-build object/image setup before start. | +| perf_bench::driver_yield (:439) | expect | Trusted benchmark scheduler invariant after start. | +| perf_bench::driver_send (:460) | expect | Trusted statically provisioned SEND cap and fixed ping-pong protocol. | +| perf_bench::partner_recv (:493) | expect | Trusted statically provisioned RECV cap and matching protocol. | +| exceptions::irq_entry (:187) | panic | Existing deliberate fatal unhandled-IRQ abort after EOI. | +| exceptions::panic_entry (:308) | panic | Existing fatal handling of unhandled exception classes. | + +All ten attributes have `reason =`; none permits unwrap. Multiline enumeration and attached-function inspection agree. Function allowances do not exempt callees. Boot/demo/benchmark reasons do not relabel live syscall input as initialization. Fatal handlers are genuinely hostile-event reachable in the existing policy: accepting these annotations preserves that policy; it does not claim full task-fault containment is implemented or authorize a new fatal policy. Future additions inside allowed functions still require review. This task is three-lint enforcement, not proof of a panic-free kernel. + +### 5. Cryptography + +| Item | Disposition, adversarial question and justification | +|---|---| +| S21 — Reviewed primitives | **N/A.** Can a new weak algorithm be exploited? No cryptography is introduced. | +| S22 — Keys absent from diagnostics | **N/A.** Can new key handling expose material? No key material/handling changes. | +| S23 — Constant-time comparisons | **N/A.** Can secret-dependent comparison timing leak? Only public lint diagnostic matching is added; no secret comparison changes. | +| S24 — Acceptable randomness | **N/A.** Can predictable randomness weaken authority? No security RNG changes; mktemp serves exclusive host temporary-directory creation. | +| S25 — Nonce/IV/salt correctness | **N/A.** Can nonce reuse violate a contract? No such operation exists in the delta. | + +### 6. Secrets and logging + +| Item | Disposition, adversarial question and justification | +|---|---| +| S26 — No secrets in diagnostics | **OK for delta.** Can new output expose cap bits or credentials? Runtime panic strings/output are unchanged; new diagnostics are fixed harness text and normal compiler/build output without secret arguments. | +| S27 — Redacted sensitive Debug | **N/A.** Can a new formatter expose a sensitive field? No Debug/Display/type changes. | + +### 7. Dependencies + +| Item | Disposition, adversarial question and justification | +|---|---| +| S28 — Dependencies evaluated under policy | **N/A.** Can unreviewed code enter through a new package? No dependency/action/binary addition or upgrade. | +| S29 — Trust category understood | **OK for delta.** Does host probing enlarge privileged runtime code? Shell orchestration remains host-only; the runtime change removes a redundant expression. | +| S30 — cargo-vet decisions updated | **N/A.** Can a new trust decision escape audit? Manifest/lock/dependency graph and vet decisions are unchanged. | + +### 8. Threat-model impact + +| Item | Disposition, adversarial question and justification | +|---|---| +| S31 — Reconciled with security model | **OK.** Can developer error newly permit a hostile-input panic? The crate-root denies strengthen detection while keeping intentional existing exceptions visible.

These checks establish enforcement in the pinned compiler; the static helper analysis supplies the MMU equivalence argument. Neither alone claims complete absence of panic or UB. + +### Supplied evidence inspected and limits + +Inspected coordinator logs in `/tmp/tyrne-b21-step5/`: host-test and Miri summaries show 46 HAL + 259 kernel + 58 test-HAL + 3 doctests = **366 passes**, two existing HAL doctests ignored. Miri records existing optimization/provenance warnings, with no UB failure. The debug smoke trace shows the real userspace greeting, userspace exit and completion, two actual EL0 SVC events (the log later repeats them in a summary) and no unexpected fault class. This is inspected supplied execution, not a QEMU/Miri run by this reviewer. + +Inspected `hosted-run.json`, `hosted-fastlane.log` and `hosted-kernel.log`: [run 38181326486](https://github.com/HodeTech/Tyrne/actions/runs/38181326486) binds b6572cc to success in all five jobs. HAL and BSP negative steps each record exit 101 with clippy::unwrap_used. Kernel log records the private 117-byte probe image and production 117 → 69 → restored 117-byte sequence. The coordinator also reports exact evidence-only HEAD 4f2c38c all five green at [run 38181458269](https://github.com/HodeTech/Tyrne/actions/runs/38181458269), verified by its read-only metadata query; this reviewer did not independently fetch that later run. + +Other broad checks remain coordinator/task-record evidence: fmt, ShellCheck/actionlint; host/default/release/perf Clippy and builds; 11 controlled probe/CLI/isolation cases; 59 QEMU-argv cases; unchanged 117-byte debug image SHA-256 `05816ccb9be5caea862dbe3e0fc45fc2068ff06cd049f2dda3459492d0ef7d88`. The controlled fixture's earlier escaped-NUL setup failure was corrected before recorded success; no failed fixture is treated as evidence. I inspected its final JSON outcomes without independently recreating that matrix. + +No independent whole-suite positive build/test/Miri, hosted fetch, QEMU, BSP unmap runtime, hardware/SMP, hostile termination cleanup, live protection, whole-tree unsafe or full architecture audit is claimed. Existing assembly/SMP issues are outside this scoped approval. Historical body preservation is evidence of audit discipline, not endorsement of every old claim. + +### Verdict and recording follow-up + +**Approve Round 1 for `8591ceb..4f2c38c`. No new finding requiring correction. Explicitly approve the changed UNSAFE-2026-0025 unmap argument/SAFETY reasoning as stated above.** All changed-surface checklist items are OK; the unchanged HIGH T-038 invariant remains flagged and excluded without downgrade.

All eight axes, 32 standard items plus the master-plan allocation item (33 total), and P1–P12. +- **Mutation boundary:** report and evidence only under `/tmp`; no repository/GitHub mutation, commit, branch change or external communication. Coordinator owns canonical report publication, index, cross-reference, trailer and append-only recording. No Done or merge action. + +### Scope and reading + +Read AGENTS and full CLAUDE; current roadmap including historical banners; numbered ADR corpus in numerical order (0001–0033, 0035–0040; no 0034 file); standards corpus and skill index; full security model/master plan and applicable skills. Bounded follow-up reads recovered truncated passages. Read T-032 and actual negative-probe harness before inspecting the implementation; also read T-037 and the full Track B.2-1 preflight for evidence limits. Read both full Round 1 reports, changed executable files, complete attached exception bodies and relevant callers, actual MMU walker/contracts, cap_unmap/FakeMmu contract, Cargo aliases, image build helper, BSP build script, workflow delta, unsafe entry/history, guide and lifecycle changes, and range commit messages. + +The runtime delta is one ignored-argument substitution inside `QemuVirtMmu::unmap`. Remaining Rust changes are lint attributes and comments; the host test harness gains two modes and CI invokes them after positive lints. No syscall body, assembly, capability policy, fatal-fault policy, dependency, toolchain, or public API changes. Git-object comparisons confirm BSP syscall, userspace shim, lockfile and toolchain pin are byte-identical to the baseline; no non-documentation change follows `c3f32c8`. + +### 1. Capability correctness + +| Item | Disposition and adversarial rationale | +|---|---| +| S01 — Privileged operations require capabilities | **OK for delta.** Can passing the root twice bypass authorization? No operation or entry point is added; unchanged `cap_unmap` resolves the capability and live arena object before MMU entry. | +| S02 — Narrowest sufficient capability | **OK for delta.** Does the reused frame broaden authority? `PhysFrame` is a copied aligned address, not a capability grant. Existing kind-based address-space authorization is unchanged. | +| S03 — Checks precede effects; failures leak no state | **OK for delta.** Can the new operand mutate before checks? No: capability/arena checks and VA alignment still precede the same walker mutation. | +| S04 — Move-only transfer | **N/A.** Could frame copying duplicate transferable authority? No capability representation or transfer changes. | +| S05 — Explicit duplication authority | **N/A.** No new capability-copy path exists to evade its authority requirement. | +| S06 — Atomic revocation | **N/A.** No revocation, CDT or concurrency operation changes that could leave partial revocation. | + +Demo task tables retain SEND/RECV for the fixed endpoint; benchmark driver/partner retain their separate SEND/RECV grants. Their IPC calls pass no transferred capability. The default EL0 table receives its console capability, not demo endpoint rights; the benchmark EL0 table is empty. This review does not invent MAP/UNMAP rights that v1 does not have, or certify unrelated existing lifecycle/revocation debt. + +### 2. Trust boundaries + +| Item | Disposition and adversarial rationale | +|---|---| +| S07 — Validate userspace input | **OK for delta.** Can arbitrary syscall input enter a newly broadly exempt scope? No family allowance exists in syscall; function exceptions retain their original routing and bodies. Independent syscall-module unwrap injection is rejected. | +| S08 — Validate user pointers through mappings | **OK for delta.** Can the placeholder root become a user dereference? The argument is unused on unmap; actual root/pointer computations and copy-user paths are unchanged. | +| S09 — Range-check buffer lengths | **OK for delta.** No buffer/window/length arithmetic or acceptance check changes. | +| S10 — Typed message parsing | **N/A.** No new wire parser or byte reinterpretation could admit malformed input. | +| S11 — IPC transfers only held authority | **OK for delta.** Trusted demo/benchmark bodies and grants are unchanged; none of the lint exceptions adds a transfer or grants foreign rights. | + +The new evidence boundary is source-to-Clippy: non-test root functions outside all allowed functions use `black_box(None::).unwrap()`. Exact `cargo host-clippy` and `cargo kernel-clippy` aliases preserve package/target/warning selection. The harness requires both nonzero exit and `clippy::unwrap_used`; unrelated failure alone and unexpected success cannot pass. It enumerates tracked current files using NUL separators, copies with modes preserved, assigns a private target directory, and uses quoted EXIT cleanup. BSP userland is built only in its private source copy, so an absent shared image cannot mask the intended diagnostic. + +Independent executions reached the intended compiler error and removed both disposable roots. The temporary fixture used paths containing spaces and `/bin/bash`. This is a regression guard over trusted source and build tools, not authentication of maliciously forged compiler output or protection against an authorized contributor rewriting both gate and code. Existing cleanup under forced termination is not newly certified. + +CI adds fixed commands within the existing required jobs, following positive lints. Trigger, permissions, action pins, secrets and cache policy are unchanged. A successful negative-probe step means the deliberate regression was rejected; it is not a red production workflow. + +### 3. Memory safety + +| Item | Disposition and adversarial rationale | +|---|---| +| S12 — Unsafe policy | **OK for changed reasoning.** Does the operand change lack justification? Adjacent SAFETY plus append-only amendment explain ignored `pa`, retained contracts and rejected allowance. Actual source SHA and real first approval are recorded. | +| S13 — Invariants hold for callers | **OK for delta; existing HIGH T-038 flagged and excluded.** Can any true-branch success/error path consume the placeholder? All intermediate calls propagate true and do not receive `pa`; the whole true leaf arm ignores it. Unchanged unrelated x2 asm contract remains defective. | +| S14 — No uninitialized exposure | **OK for delta.** The return frame remains masked from the existing L3 descriptor; placeholder contents never enter a descriptor or result. | +| S15 — No use-after-free; justified lifetimes | **OK for delta.** Copying `PhysFrame` neither frees nor acquires ownership nor extends lifetime. Root/table validity and exclusive ownership remain caller obligations. | +| S16 — Aliasing discipline | **OK for delta.** Two value copies create no mutable references; address-space borrow and descriptor access scopes are unchanged. | + +**Explicit unsafe approval:** Reviewed the changed `unsafe` call and adjacent SAFETY reasoning in `bsp-qemu-virt/src/mmu.rs:307–333`, particularly `walk_and_install_leaf` at :319–328; I agree with and approve the changed SAFETY reasoning under **UNSAFE-2026-0025**. With literal `unmap = true`, `pa` is unused. Replacing the infallible dummy-zero frame construction/unwrap with already-valid `as_.root` preserves the operation under the existing root/table validity, ownership and lifetime contracts. + +The actual helper computes indices from VA, traverses the same L0/L1/L2 tables, returns unchanged typed errors for missing/block mappings, reads the existing L3 descriptor, masks its output PA, clears that leaf slot and returns the descriptor-derived frame. `pa` appears operationally only in the false/map arm, where it is encoded and returned. The new value affects no pointer, descriptor access, allocation, return value or error. Root argument, VA, flags, null provider and true selector are identical. `PhysFrame` is Copy, has no ownership/destructor effect, and the removed constructor always accepts aligned zero. The caller still receives `MapperFlush`; unchanged `cap_unmap` flushes before returning the frame. + +Independent historical-byte verification removes exactly the new T-032 amendment plus Round 1 recording (2,571 bytes) and reconstructs the complete baseline audit log byte-for-byte. Thus original fields and prior amendments are preserved. The new amendment accurately identifies `c3f32c8`; it does not silently rewrite the old SMP claim. + +**Round 1 recording verified:** Read both complete canonical reports. The security report explicitly Approves the changed call/reasoning for `8591ceb..4f2c38c`, limits its approval to the ignored-argument equivalence, excludes runtime BSP unmap/SMP/T-038, and asks for append-only actual approval recording. The code report explicitly agrees and records the distinct security result. The appended recording at `6e191e2` states those same facts and preserves the earlier pending sentence as history. Its real commit message contains `Audit: UNSAFE-2026-0025` and `Security-Review: b21_step5_round1_security (docs/analysis/reviews/security-reviews/2026-10-12-t032-panic-family-denies.md)`. No fabricated or retroactive implementation-commit approval is present. + +**Limits retained:** ordinary smoke exercises boot/map, not this BSP unmap branch. The FakeMmu test asserts returned PA and both flushes; rollback tests concern kernel-layer cleanup, not physical BSP table walking. No runtime BSP unmap test was newly executed. The original SMP-forward claim is expressly not endorsed; T-069 retains ownership. This narrow proof does not certify the whole walker or historical caller-contract debt. + +**Existing HIGH T-038 retained:** the userspace shim declares x2 input-only while the unchanged BSP return path writes x2. Both files are byte-preserved. Clean Clippy, host Miri and successful guest boot cannot certify that assembly; this review neither fixes nor downgrades it. + +### 4. Kernel-mode discipline + +| Item | Disposition and adversarial rationale | +|---|---| +| S17 — No ISR allocation | **OK for delta.** IRQ annotation adds no allocation; its unchanged timer/spurious paths return and unhandled path EOIs before fatal abort. | +| S18 — Bounded loops | **OK for delta.** No attacker-dependent loop is introduced. Existing idle/parking/cooperative loops remain unchanged; no new blanket termination claim. | +| S19 — Minimal critical sections | **OK for delta.** No lock, IRQ mask, borrow lifetime or context-switch sequencing changes. | +| S20 — No new hot-path panic | **OK.** One redundant unwrap is removed; no new runtime panic/expect appears. Exactly ten reasoned function exceptions, with no HAL/syscall/MMU family allow. | +| MP-1 — Allocation exhaustion returns typed errors | **OK for delta.** No new allocation or conversion of attacker-driven failure to expect. Existing trusted setup exceptions stay scoped; MMU error paths are unchanged. | + +#### Full exception inventory + +| Function | Allowed family members | Classification and boundary | +|---|---|---| +| `main::kernel_main_high` | expect, panic | One-shot trusted static image/capacity/object setup before scheduler start. | +| `main::idle_entry` | expect | Post-start trusted current-task invariant; accurately not described as initialization. | +| `main::task_a` | expect, panic | Trusted one-round kernel demo and fixed IPC protocol. | +| `main::task_b` | expect, panic | Trusted matching receiver/reply demo protocol. | +| `perf_bench::run` | expect, panic | One-shot trusted measurement-build setup and publish-before-start sequence. | +| `perf_bench::driver_yield` | expect | Trusted current-task invariant after scheduler start. | +| `perf_bench::driver_send` | expect | Static SEND capability and fixed ping-pong protocol. | +| `perf_bench::partner_recv` | expect | Static RECV capability and fixed matching protocol. | +| `exceptions::irq_entry` | panic | Existing deliberate fatal unhandled-IRQ abort after EOI. | +| `exceptions::panic_entry` | panic | Existing fatal unhandled-exception policy. | + +All ten groups have reasons and attach to functions; none permits unwrap. Full bodies, multiline attributes and variant selection were inspected. Fatal exception handling is hostile-event reachable under the existing policy; approval of its annotation is not a claim of full task-fault containment and does not allocate that unchanged debt to a future phase. Future changes inside these allowed functions remain review-sensitive. Assertions are outside these three lints; no panic-free-kernel claim follows. + +### 5. Cryptography + +| Item | Disposition and adversarial rationale | +|---|---| +| S21 — Reviewed primitives | **N/A.** No cryptographic primitive is introduced or changed. | +| S22 — Keys absent from diagnostics | **N/A.** No key handling or key-bearing diagnostic is added. | +| S23 — Constant-time comparison | **N/A.** Public diagnostic matching is not a secret comparison; no cryptographic timing path changes. | +| S24 — Acceptable randomness | **N/A.** No security RNG change. Host mktemp creates an exclusive disposable directory, not a cryptographic token. | +| S25 — Nonce/IV/salt discipline | **N/A.** No such state or operation changes. | + +### 6. Secrets and logging + +| Item | Disposition and adversarial rationale | +|---|---| +| S26 — No sensitive diagnostic leakage | **OK for delta.** Runtime diagnostics are unchanged; new output is fixed test status and compiler/build output, with no new secret argument. | +| S27 — Redacted sensitive Debug | **N/A.** No new type/formatter could reveal capability identity or key fields. | + +### 7. Dependencies + +| Item | Disposition and adversarial rationale | +|---|---| +| S28 — Dependencies evaluated under policy | **N/A.** No crate, action or binary dependency is added/upgraded. | +| S29 — Trust category understood | **OK for delta.** Additional probing is host-only; no unreviewed runtime component enters the TCB. | +| S30 — cargo-vet decisions recorded | **N/A.** No dependency graph/trust decision changes; lockfile preserved. | + +### 8. Threat-model impact + +| Item | Disposition and adversarial rationale | +|---|---| +| S31 — Reconciled with security model | **OK.** The change improves detection of developer error on hostile-input paths while keeping intentional exceptions explicit; runtime authority, user-memory and hardware boundaries remain unchanged. | +| S32 — Model changes recorded/tracked | **N/A — no model shift.** No new adversary/principal or defense claim is introduced. Existing fatal handling, SMP and assembly limitations remain explicit. | + +Accepted ADR-0040 governs the consolidation workflow; existing MMU/direct-map/image ADRs govern the preserved implementation contracts. No architecture or standard policy is changed through attributes, and no new ADR is required for the ignored-value substitution. + +### Architectural principles P1–P12 + +| Principle | Disposition | +|---|---| +| P1 — No ambient authority | **OK:** no authority surface added or bypassed. | +| P2 — Small defensible TCB | **OK:** host probes add no privileged runtime subsystem. | +| P3 — Userspace drivers | **N/A:** placement unchanged. | +| P4 — Capability boundaries | **OK for delta:** checks unchanged; syscall module retains lint enforcement. | +| P5 — Rust/audited unsafe | **OK for changed reasoning:** explicit 0025 approval; existing T-038 excluded. | +| P6 — HAL separation | **OK:** crate-root enforcement preserves the abstraction boundary. | +| P7 — No proprietary blobs | **OK:** no committed binary; private image built from source. | +| P8 — ADR governance | **OK:** existing Accepted policy implemented, history preserved. | +| P9 — English | **OK:** changed repository prose/code/diagnostics English. | +| P10 — Mermaid | **N/A:** no diagram needed or changed. | +| P11 — Reproducibility | **OK for delta:** pin/lock preserved and independent private image matches recorded hash; no whole-kernel reproducibility certification. | +| P12 — Complete scoped work | **OK for this review:** concrete implementation/evidence exists; coordinator must record Round 2 and retain final human PR/Done boundaries. | + +### Independent execution and evidence + +Independent execution used the pinned nightly, `/bin/bash`, Python `TemporaryDirectory` paths with spaces, private source copies and private CARGO_TARGET_DIR.

Metadata binds completed success to exact `b6572cc65857b99f3ac3661b99cea809a7b12e88`, with all five jobs successful in [run 38181326486](https://github.com/HodeTech/Tyrne/actions/runs/38181326486). Supplied fast-lane line 202 and kernel line 214 show the intended HAL/BSP unwrap rejection at exit 101; kernel line 213 shows its private 117-byte image. Production image sequence is 117 → 69 → restored 117 bytes (lines 173/244/276). Fast-lane summaries establish 366 debug and 356 release passes plus two ignored HAL doctests.

These two later runs are coordinator-retrieved metadata attribution, not independent retrieval by this reviewer. All non-documentation files are unchanged after the detailed hosted source/evidence tip. + +Other broad validation remains coordinator/task/first-review attribution: fmt/ShellCheck/actionlint; default/release/perf builds and Clippy; 366 host and Miri passes, existing Miri warnings and two ignored doctests; real debug greeting/exit/completion/two SVCs/no unexpected fault; eleven controlled probe/CLI cases and 59 QEMU argv cases. The full R1 reports document independent unwrap-deny-removal controls and root expect/panic checks in both crates.

Existing HIGH T-038 remains unchanged and excluded. +- **Verdict:** **Changes requested. One new HIGH finding, SEC-T034-R1-01.** + +### Scope, reading and provenance + +This review covers the CI job, profile-aware smoke gate, stdlib-only Python regression harness, private actual-kernel mutations, uploaded evidence, matching-profile build order and documentation. The security trigger is boot/syscall assurance and CI supply-chain/authorization trust; it does not require shipped kernel changes to warrant a dedicated pass. + +Read AGENTS, full CLAUDE, current roadmap, ADRs numerically (0001–0033 and 0035–0040; no 0034 file), all standards, both skills, the full security review master plan and security model. Truncated prerequisite reads were recovered with bounded reads. Read T-034 before implementation, then the new fixtures/harness before analyzing the smoke implementation and workflow. Examined prior T-030 security review discussion for the release boundary, changed documentation, unchanged build-userland orchestration and the current T-038 assembly mismatch. This is not a re-audit of all historical ADR-governed code. + +No repository edits, commits, branch changes or GitHub writes were performed. Own experiments used disposable private copies/targets/images and new `/tmp` evidence paths. Shared evidence directories were read only. This agent independently queried the official upload-action tag and action metadata through read-only GitHub API calls, and consulted official GitHub shell documentation. Hosted run/artifact downloads were supplied by the coordinator and independently inspected locally; this agent did not fetch or rerun that hosted job. + +### New finding SEC-T034-R1-01 — HIGH: tee discards production smoke failure + +**Location:** `.github/workflows/ci.yml:237` and `:243`, the debug and release production smoke `run:` pipelines; no workflow/job/step shell override exists at this tip. + +**Problem and impact:** each command runs `tools/smoke.sh ... 2>&1 | tee ...` under GitHub's unspecified Linux shell, `/usr/bin/bash -e {0}`. This shell does not enable `pipefail`. When smoke correctly rejects missing EL0 markers, a fault, or a forbidden release greeting with status 1, successful `tee` makes the step return 0. Therefore the production guest rejection is not a blocking CI result. An actual guest regression or execution failure can be hidden by the logging wrapper if later independent checks pass. This directly defeats the requested merge-gating runtime assurance; there is no claim that the observed clean hosted boot itself was bad. + +**Proof:** official [GitHub workflow shell documentation](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax) distinguishes unspecified `bash -e` from explicit `shell: bash`, which adds `-o pipefail`. Supplied hosted log `/tmp/tyrne-b21-step6/hosted-qemu.log:748` and `:823` confirms both exact production steps actually used `/usr/bin/bash -e {0}`. + +Independently copied the unchanged smoke script into a disposable path containing spaces/metacharacters, extracted each exact `run:` command from the workflow, supplied an explicit private ELF, and used a QEMU stub only to deliver controlled traces. These are workflow-integration fixtures, not claims of actual fault injection: + +| Trace delivered to actual smoke | Actual default shell exit | Explicit Bash with pipefail exit | Actual diagnostic | +|---|---:|---:|---| +| Debug completion only | 0 | 1 | Greeting and userspace-exit markers missing | +| All debug markers plus `Data Abort` | 0 | 1 | Panic / CPU-fault class appeared | +| Release exit/completion plus greeting | 0 | 1 | Forbidden userspace greeting | + +Complete six-case output is `/tmp/tyrne-b21-t034-r1-security-pipeline.json`. The smoke script's own `set -euo pipefail` affects its child shell, not the parent workflow pipeline. The direct Python harness correctly checks smoke return codes but does not exercise this outer `tee` pipeline, explaining why all 23 cases can pass while the integration defect remains. + +**Required correction:** enable Bash pipefail for both production steps, for example job-scoped `defaults.run.shell: bash`, and add a regression that sends a known rejecting trace through the same CI pipeline/shell and asserts nonzero plus the intended smoke diagnostic. Re-run relevant local checks and hosted clean guests, and review the fix before required-check registration. A fix is not present in this reviewed range. + +### 1. Capability correctness + +Adversarial question: can the change grant useful privileged effects without the required authority? + +| Item | Disposition and justification | +|---|---| +| S01 — Every introduced privileged operation requires a capability | **N/A to runtime.** No kernel operation is introduced; host artifact upload uses runner credentials and unchanged read-only repository token scope, with no new runtime authority. | +| S02 — Narrowest sufficient capability | **OK for delta.** Workflow keeps `contents: read`, checkout does not persist credentials, and artifact upload does not request a broader repository token. | +| S03 — Check capabilities before effects; failed checks leak no state | **N/A to runtime.** No capability-check ordering or denial path changes; release greeting checks observe the existing debug-console contract rather than alter it. | +| S04 — Transfer is move-only | **N/A.** No capability transfer, representation or ownership changes. | +| S05 — Duplication requires explicit authority | **N/A.** No duplication operation, right or caller changes. | +| S06 — Revocation is atomic | **N/A.** No revocation, capability-table mutation or concurrency behavior changes. | + +The release smoke's absent greeting is evidence of the ordinary program's observed console behavior, not exhaustive proof that hostile callers cannot obtain output. ADR-0031's capability/debug gating and its host regressions remain separate enforcement layers. + +### 2. Trust boundaries + +Adversarial question: can bad input be interpreted as trustworthy successful evidence or escape its intended execution boundary? + +| Item | Disposition and justification | +|---|---| +| S07 — Validate userspace inputs before kernel use | **N/A to changed runtime.** No syscall argument consumer changes; the changed CI evidence boundary has the separate HIGH finding above. | +| S08 — User pointers only through validated mappings | **N/A.** No pointer access or translation code changes; source-built guest execution does not certify every existing mapping invariant. | +| S09 — Range-check user buffer lengths | **N/A.** No user length, mapped-region bound or copy routine changes. | +| S10 — Parse userspace messages into typed structures | **N/A.** No IPC wire format or privileged parser changes; public serial strings remain a host regression-test interface. | +| S11 — IPC grants no excess or untransferred authority | **N/A.** No IPC authority operation changes. | + +**Changed CI boundary — flagged HIGH.** Smoke's exact full-line required markers close the old completion-only false-positive baseline; release forbids the greeting anywhere, and both profiles reject the existing six fault/panic patterns. Nevertheless, the workflow discards smoke's failure through `tee` (SEC-T034-R1-01). The smoke return code must survive every boundary to the status check. + +**Host command boundary — OK within scope.** Python uses argument vectors without `shell=True`; names, profiles, mutation text and diagnostic strings are fixed in source. Paths are pathlib objects or quoted shell arguments. No PR-title/body/branch interpolation is added to shell code. The harness clears QEMU_SMP, fixes its actual probes at the existing default one CPU, validates mutation anchors exactly once and refuses unrelated build errors. PATH, source/build tools and the selected checkout are trusted execution inputs: this is regression testing, not attestation against a malicious repository author, compiler, QEMU executable or same-user host process. + +**Private experiment boundary — OK.** `TemporaryDirectory` creates the private root; only NUL-delimited `git ls-files` entries are copied, with modes preserved. No `.git`, ignored hello.bin or normal target directory is copied. The actual builds use a sibling private CARGO_TARGET_DIR and write hello.bin only inside the copied tree. Each profile builds its matching userland before its BSP. Actual variants require exact expected marker shapes and no unrelated fault, in addition to status 1 and the intended diagnostic. A compile failure cannot qualify as an intended negative. + +**Refusal and cleanup — OK for ordinary exits.** Existing artifact paths are refused before mutation; artifacts intentionally retained outside the scratch tree have `completed:false` until every case succeeds. Independent unrelated compiler-failure injection exited 1, retained exactly 20 completed synthetic cases, and left no private scratch tree. Retrying with the existing artifact directory exited 2 without changing results; unknown/abbreviated flags also exited 2. Ordinary success is managed by the same TemporaryDirectory context. No guarantee is claimed for forced process kill or machine loss; CI's outer ten-minute timeout is the final resource bound. + +### 3. Memory safety + +Adversarial question: can this delta create unsafe memory access or cause existing assembly defects to be treated as proven safe? + +| Item | Disposition and justification | +|---|---| +| S12 — New unsafe satisfies unsafe-policy | **N/A.** No shipped Rust/assembly, unsafe body, enclosing compilation predicate or safety argument changes. | +| S13 — Safety invariants hold at every call site | **Flagged — existing HIGH T-038, unchanged and excluded.** The userland console shim still declares x2 input-only while BSP resume writes saved x2; passing guest/lint tests does not validate that contract. | +| S14 — No uninitialized memory exposed | **OK for delta.** Host Python/shell orchestration adds no kernel buffer or initialization change; retained logs do not dump newly introduced memory. | +| S15 — No use-after-free; raw-pointer lifetimes justified | **N/A.** No raw-pointer lifetime, allocator or ownership changes. | +| S16 — No aliasing violations | **N/A.** No kernel reference construction, aliasing or synchronization changes. | + +Read-only inspection confirms T-038 at `userland/tyrne-user/src/lib.rs` (`in("x2")`) versus `bsp-qemu-virt/src/syscall.rs` (`f.x2_x3[0] = r.payload[1]`). It retains HIGH severity. Neither this review nor the real negative kernels resolve it. The private text mutations do not become shipped Rust changes and require no new unsafe approval. + +### 4. Kernel-mode discipline + +Adversarial question: can a caller newly exhaust or stall the kernel through this change? + +| Item | Disposition and justification | +|---|---| +| S17 — No allocation in ISRs | **N/A.** No ISR or kernel allocation path changes. | +| S18 — Kernel loops bounded | **N/A to kernel delta.** Existing completed-demo spin remains intentional; host smoke bounds it, and the job has a ten-minute outer timeout. | +| S19 — Critical sections minimized | **N/A.** No scheduler state, lock, interrupt masking or critical section changes. | +| S20 — No new hot-path kernel panic | **OK for delta.** New failures are host test/command exits; shipped kernel panic behavior is unchanged. | +| MP-1 — Allocation exhaustion returns typed errors, never panics | **N/A.** No kernel allocation/exhaustion contract changes; host I/O/build failure is not accepted as evidence of the intended guest rejection. | + +The harness has finite fixture/variant lists. It does not individually time-limit Cargo, so standalone local compilation depends on tool completion; CI supplies the encompassing ten-minute bound. Captured trace/log memory and disk scale with trusted guest output and runtime; no new local-task kernel resource surface is introduced. This is not an SMP, hardware or denial-of-service proof. + +### 5. Cryptography + +Adversarial question: can secret-dependent operations or weak primitives create a new attack? + +| Item | Disposition and justification | +|---|---| +| S21 — Reviewed primitives, no homemade crypto | **OK for delta.** Smoke provenance uses Python stdlib SHA-256, not a custom algorithm; it is a diagnostic digest, not a signature or authenticity guarantee. | +| S22 — Keys absent from logs/errors/Debug | **N/A.** No key material, cryptographic key operation or key serialization is introduced. | +| S23 — Constant-time comparisons where needed | **N/A.** Compared markers, profiles and mutation anchors are public test data. | +| S24 — Acceptable randomness | **N/A to cryptographic operations.** TemporaryDirectory provides exclusive host temporary storage, not kernel security-token generation. | +| S25 — Correct nonces/IVs/salts | **N/A.** No nonce, IV, salt or encryption protocol changes. | + +### 6. Secrets and logging + +Adversarial question: can a diagnostic upload disclose credentials, capability tokens or private host material? + +| Item | Disposition and justification | +|---|---| +| S26 — No secrets in diagnostics | **OK for reviewed source/evidence.** New uploads target one dedicated runner-temp evidence directory containing trace/build logs and public provenance, not the checkout, home, Cargo cache, process environment or credential store. | +| S27 — Sensitive Debug implementations redact or are absent | **N/A.** No type formatter or sensitive representation changes. | + +Inspected hosted production raw traces, metadata and probe results. They include public kernel addresses, demo IPC labels, tool versions and host paths; these are diagnostic exposure in an isolated CI guest, not capability-token/key disclosure. No new secret environment is supplied. Artifact selection is deliberately narrow and upload always runs with 14-day retention; `if-no-files-found:error` refuses silently missing evidence. The action's default excludes hidden files and does not overwrite an existing artifact. Early failure retains only available diagnostics; cancellation/runner loss can prevent upload, and this report does not promise otherwise. Arbitrary malicious build source could print arbitrary accessible data, which is why CI must not receive secrets; the change preserves that premise. + +### 7. Dependencies + +Adversarial question: is new executable trust pinned, understood and confined to the intended layer? + +| Item | Disposition and justification | +|---|---| +| S28 — New dependencies evaluated under policy | **OK.** New upload action is full-SHA pinned; Python uses only stdlib and no pip/Cargo dependency is added; QEMU is installed from the runner's apt repositories as explicitly authorized by T-034. | +| S29 — Dependency trust category understood | **OK.** Python, QEMU and the upload action are host/CI dependencies, not new kernel-linked code; their execution remains inside the hosted job's existing trust boundary. | +| S30 — cargo-vet decisions updated | **N/A.** Cargo.lock and external Rust dependency/trust graph are unchanged; no cargo-vet decision is introduced. | + +Independently queried official `actions/upload-artifact` tag `v7.0.2`: it resolves directly to commit `cf430e030ddbb5b0abf93d22962f4752f3646cd9`, exactly the workflow pin. Read that commit's `action.yml`: Node 24 runner, default archive true, hidden-files false, overwrite false, artifact digest output. Parent also supplied its official source verification. This is provenance/configuration review, not a complete audit of bundled JavaScript dependencies. Existing checkout/cache full SHAs and nonpersisted checkout credentials remain. The separate smoke cache namespace does not share probe targets; normal Cargo cache/source/compiler trust remains an existing assumption. + +QEMU and ubuntu-latest are intentionally rolling host packages, so the job records QEMU/Rust version evidence rather than claiming identical host environments forever. Matching userland is built from source before each profile; no proprietary or prebuilt guest blob is introduced. + +### 8. Threat-model impact + +Adversarial question: can a failed execution acquire a misleading trusted green status, or is a broader protection being claimed than was established? + +| Item | Disposition and justification | +|---|---| +| S31 — Reconciled with security-model.md | **Flagged HIGH for changed assurance boundary.** The intended developer-error/boot regression defense is undermined when workflow logging converts a detected smoke failure into success (SEC-T034-R1-01); runtime capability/MMU/IPC trust remains unchanged. | +| S32 — Model shift updated or follow-up linked | **N/A — no runtime model shift.** No new runtime principal, authority, DMA protection or adversary class is introduced; the fix needed is CI failure propagation, not a new kernel threat-model ADR. | + +Accepted ADR-0040 governs the approved development sequence and ADR-0031/0039 govern profile behavior/image provenance. Exact SVC counting, malicious EL0 images, SMP behavior, real hardware and whole-kernel assembly correctness remain explicitly outside this smoke claim. A forged marker stream can pass a marker checker; it is not a cryptographic attestation system. + +Live protection registration is intentionally still pending after the first hosted green and both fresh review rounds. Supplied read-only baseline names the four existing checks, strict true, each app ID 15368; parent-supplied current check metadata names the new display check. The future required context must be `QEMU debug + release smoke (nightly)`, preserving all existing settings/app bindings. Pending registration/final PR is not independently a false-completion finding: T-034 stays In Review and the live/final-PR checkboxes remain unchecked. The new HIGH defect must be corrected first. This reviewer made no live-policy changes and does not certify final read-back. + +### Architectural principles P1–P12 + +| Principle | Disposition | +|---|---| +| P1 — No ambient authority | **OK for delta:** no runtime grants or permission widening. | +| P2 — Smallest defensible TCB | **OK:** new orchestration remains host-only; kernel TCB bytes unchanged. | +| P3 — Drivers/filesystems/network in userspace | **N/A:** no subsystem placement change. | +| P4 — Capability checks at boundaries | **OK for runtime delta:** no capability boundary changes; CI assurance boundary is separately flagged HIGH. | +| P5 — Rust kernel with disciplined assembly | **OK for delta:** Python/shell are host tooling; no assembly soundness claim or new unsafe approval. | +| P6 — HAL isolation | **N/A:** no architecture-dependent kernel/HAL interface change. | +| P7 — No proprietary blobs | **OK:** userland guest images remain source-built and private variants disposable. | +| P8 — Decisions in ADRs | **OK:** Accepted ADR-0040 authorizes the gate; no conflicting policy decision introduced. | +| P9 — English repository | **OK:** changed scripts, messages and docs are English. | +| P10 — Mermaid diagrams | **N/A:** no new diagram. | +| P11 — Reproducibility | **OK for delta:** Rust pin/lockfile unchanged, source/hash/dirty-state and runtime versions recorded; no bit-for-bit reproducibility claim. | +| P12 — No half-finished main | **Flagged for intended gate readiness:** SEC-T034-R1-01 blocks this step's approval; development/In Review sequencing and pending final maintainer PR are otherwise accurately represented. | + +### Executed evidence and limitations + +**Own execution:** real `tools/test-smoke-gates.sh --real --artifact-dir /tmp/tyrne-b21-t034-r1-security-real` exited 0 on macOS with QEMU 11.1.1 and Python 3.9.6. It independently ran all 20 synthetic fixtures and built/booted all three actual private kernels. Its results bind clean `41d9682` and smoke SHA-256 `a48aada8f9b1b1173f9be73c3a2715b9bf3932246bc7457bcc1296f65abddba8`. All cases passed, completed true. Raw actual traces independently checked: + +- Omit EL0: completion present, greeting/exit absent, no unrelated fault; smoke exit 1. +- Omit completion: greeting/exit present, completion absent, no unrelated fault; smoke exit 1. +- Release greeting: all three markers present, no unrelated fault; smoke exit 1. + +Own files also include `/tmp/tyrne-b21-t034-r1-security-real.log`, the six-case pipeline matrix named above, `/tmp/tyrne-b21-t034-r1-security-refusal.json`, and incomplete-by-design build-failure evidence `/tmp/tyrne-b21-t034-r1-security-buildfail/`. The latter proves infrastructure failure is rejected, not counted as a successful negative guest. `git diff --check 07449f1..41d9682` passed; final checked worktree was clean. No shared image or kernel output was built by this reviewer. + +**Inspected supplied hosted evidence:** `/tmp/tyrne-b21-step6/hosted-artifact/`, `hosted-run.json`, `hosted-qemu.log`, and `protection-before.json`. [Run 38183035717](https://github.com/HodeTech/Tyrne/actions/runs/38183035717) binds source `6450005`, all six jobs green. Artifact metadata records attempt 1, QEMU 8.2.2, rustc 1.94.0-nightly, x86_64 Linux, evidence interval 96 seconds. Parent reports full job wall time 101 seconds and artifact ID 11718825340, 23,768 bytes, service digest `5e72ef571d9625205d340e7a0279e7e912cd89f34de8c565bc97e74687e8babf`; that service digest was not independently recomputed from an original archive here. + +Independently inspected both raw production traces: debug has all three exact markers; release has exit/completion and no greeting; neither matches a fault pattern. Hosted probe JSON binds clean source and the same smoke hash, all 23 completed/pass cases, with all three actual marker shapes/no unrelated faults matching own results. These prove the clean guests ran and the direct gate rejects the covered mutations. They do not prove the defective production workflow propagates a rejection. The reported green run and HIGH finding are consistent. + +The old omitted-EL0 baseline JSON was inspected as supplied evidence: at `6e191e2`, missing greeting/exit and present completion still produced old smoke status 0. This was not re-executed by this reviewer. Parent's broader fmt/clippy/actionlint/ShellCheck/366-host-test suite and clean local production smokes are supplied evidence, not independently repeated here. No full Miri/host suite, hardware/SMP run, actual CPU-fault injection, live required-policy application, or post-fix verification is claimed. + +### Verdict + +**Changes requested for `07449f1..41d9682`.** SEC-T034-R1-01 is a verified new HIGH blocker: production smoke rejection is masked by `tee` under the hosted default shell. All eight axes, 33 checklist items and P1–P12 are disposed above; no other new actionable security finding was established. Existing HIGH T-038 remains unchanged/excluded and undowngraded. + +The coordinator owns fixing the workflow, local/hosted verification, subsequent fresh reviews, canonical publication/index/cross-reference and truthful trailers. This report grants no approval trailer, Done promotion, live registration or merge authorization. T-034 remains In Review and final maintainer PR remains pending. + +## Round 2 security review + +This independent, fresh security pass approves the corrected T-034 implementation for its scoped development step. The Round 1 HIGH pipeline-masking finding is fixed and regression-sensitive; no new actionable security finding was established. Existing HIGH T-038 remains excluded, unchanged and undowngraded. + +- **Change:** `development`, base `07449f19bbe957ea3649724d8f3786947ae881cb` through executable source `97a6c836e6180b2e61f1242560977ee21995258d`; evidence-only documentation follow-up `9092581f1363c19cd3943c4d3a95a0d0c8634540` also reviewed. Exact IDs verified with Git. +- **Reviewer:** independent Codex agent `/root/b21_step6_round2_security`, acting for the maintainer; agent identity is not a maintainer sign-off or runtime model attestation. +- **Date:** 2026-10-12, Europe/Istanbul. +- **Separation:** fresh security reviewer with an empty checklist, distinct from implementation and Round 2 code review. The entire completed report is supplied to the code reviewer before that review's final verdict. +- **Procedure:** `perform-security-review` and `conduct-review`; security master plan, all eight axes, all 32 standard items plus its allocation-exhaustion item (33 total), and P1–P12. +- **Unsafe audit cross-reference:** no shipped Rust, assembly, unsafe body, safety argument or audit-log change. No new unsafe approval is applicable. T-038's existing x2 clobber mismatch is explicitly retained. +- **Verdict:** **Approve** the reviewed scoped delta; zero new actionable findings. This is not Done promotion, a final maintainer PR approval, or live-policy read-back certification. + +### Scope, reading and provenance + +Read AGENTS, full CLAUDE, current roadmap, numerical ADR corpus (0001–0033 and 0035–0040; there is no 0034 file), all standards, relevant skill inventory, both review skills, full security master plan and full security model. T-034 was read before implementation. Read both full canonical Round 1 code/security reports, including their historical Requests changes and current reconciliation. Oversized prerequisite outputs were recovered with bounded reads; changed workflow context, full smoke/build scripts, complete Python harness/wrappers, new pipeline probe, task and changed guide/standard documentation were examined. Evidence-only follow-up keeps the historical finding and correct In Review status. + +No repository edits, commits, branch operations, GitHub writes or shared image/kernel builds were performed. Own experiments used private disposable directories and explicit evidence outputs under `/tmp`. Parent-downloaded hosted evidence was inspected locally, not independently fetched or rerun by this reviewer. Prior reports' executions and parent-reported checks are identified as supplied evidence, not relabeled as own execution. This pass is scoped infrastructure review, not a whole-kernel re-audit. + +### Round 1 HIGH disposition: fixed and independently verified + +Round 1 `SEC-T034-R1-01` / `CODE-T034-R1-01` identified that successful `tee` discarded an actual smoke rejection under the unspecified hosted `bash -e` shell. Commit `97a6c83` supplies `qemu-smoke.defaults.run.shell: bash`. Both production steps and the new guard inherit it, with no step override, `continue-on-error` or replacement success wrapper. Corrected hosted logs confirm `/usr/bin/bash --noprofile --norc -e -o pipefail {0}` for the guard, debug and release steps. + +The permanent guard runs the actual smoke entry point against a synthetic completion-only trace, passes its output through the caller's `tee`, rejects a zero pipeline status, then requires the real missing-task-exit diagnostic. The probe does not manufacture smoke diagnostics or catch/rewrite smoke's status. Its own shell options do not set the caller's options; the new job default is what repairs production propagation. + +**Own independent sensitivity experiment:** extracted the exact guard body from the workflow; copied unchanged probe/smoke scripts to a disposable path containing spaces and a semicolon; ran it with identical environment under both shell modes. Evidence: `/tmp/tyrne-b21-t034-round2-security-pipeline.json`. + +| Control | Guard exit | Interpretation | +|---|---:|---| +| Broken `bash -e` | 1 | Guard detects that `tee` hid the actual missing-EL0 rejection. | +| Corrected explicit Bash with `-eo pipefail` | 0 | Actual smoke exit propagates; real missing-exit diagnostic is required and present. | +| Corrected shell, private smoke script deliberately absent | 1 | Unrelated tool failure does not qualify as intended smoke rejection. | + +Each control left its private scratch directory empty. The missing-script control was private and did not modify repository source. This proves the test is sensitive both to the reported integration defect and to an accidental failure in place of the intended diagnostic. Parent and code-reviewer controls independently reach the same shell sensitivity result; those are corroboration, not this reviewer's executions. + +The initial hosted run at `6450005` established clean guests and direct negative probes only; it did not establish failed-pipeline propagation. The corrected hosted run and own sensitivity controls resolve that gap. The historical Round 1 verdict remains Requests changes for its original range. + +### 1. Capability correctness + +Adversarial question: can this change acquire a privileged effect without the required authority, or silently widen the job's authority? + +| Item | Outcome and justification | +|---|---| +| S01 — Every introduced privileged operation requires a capability | **N/A to runtime:** no kernel operation is introduced; host artifact upload uses runner artifact credentials, not a new runtime capability or repository-write grant. | +| S02 — Narrowest sufficient authority | **OK:** workflow remains `contents: read`, checkout keeps `persist-credentials: false`, and no new secret or widened job permission is added. | +| S03 — Capability check precedes observable side effects | **N/A:** no capability check, denial path or runtime effect ordering changes. | +| S04 — Capability transfer is move-only | **N/A:** no transfer representation, ownership or IPC operation changes. | +| S05 — Duplication requires explicit authority | **N/A:** no duplicate capability operation, right or caller changes. | +| S06 — Revocation is atomic | **N/A:** no capability-table mutation, revocation or concurrent state changes. | + +The observed release greeting prohibition tests the existing debug-console behavior. It is not a new runtime authorization mechanism or exhaustive proof about hostile console callers. + +### 2. Trust boundaries + +Adversarial question: can failed execution cross into a trusted green status, or can test data escape its private host execution boundary? + +| Item | Outcome and justification | +|---|---| +| S07 — Validate userspace input before kernel use | **N/A to runtime:** syscall argument handling is unchanged; the changed host evidence boundary now propagates smoke rejection through pipefail. | +| S08 — User pointers only through validated mappings | **N/A:** no user pointer dereference, translation or mapping path changes. | +| S09 — Range-check user buffer lengths | **N/A:** no mapped-region length or user-copy contract changes. | +| S10 — Typed parsing of user messages | **N/A:** no IPC parser or privileged wire format changes; public serial lines are a host test interface. | +| S11 — IPC grants only held and explicitly transferred authority | **N/A:** no IPC transfer or authority operation changes. | + +**CI status boundary — OK.** Exact whole-line required markers reject prefixed/suffixed approximations; release forbids the greeting anywhere; both profiles reject six panic/fault strings. Child failure survives `tee` under the corrected inherited shell. Explicit ELF calls skip compilation and require explicit `--release` for release expectations. Fault fixtures exercise the actual smoke consumer; they are not real CPU-fault injections. + +**Command/data boundary — OK.** Python passes argv lists without `shell=True`; profiles, mutation anchors and expected diagnostics are fixed source data. Shell paths are quoted, and no PR title/body/branch expression is injected into shell code. Environment/source/compiler/QEMU executables are trusted host inputs. This is a regression gate against developer mistakes, not attestation against a malicious repository author or compromised runner. + +**Isolation — OK.** The real harness copies NUL-delimited tracked files with preserved modes into a `TemporaryDirectory`, excluding ignored normal images and targets. Its CARGO_TARGET_DIR is a private sibling, and its userland build writes hello.bin only under the copied source. Each profile builds matching userland before BSP. Each mutation requires an exact single anchor; each actual negative requires exit 1, its intended diagnostic, the exact marker shape and no unrelated fault. A failed compile cannot pass as a successful negative boot. QEMU_SMP is removed from the harness environment; the new caller probe explicitly sets one CPU, and hosted production uses the existing single-core default. + +**Lifetime/evidence — OK.** Context-managed cleanup removes scratch source/target/images on ordinary success and exceptions. Existing artifact directories are refused, and results remain `completed:false` until all cases succeed. The real private run left the shared hello.bin and debug/release kernel hashes unchanged. Forced kill/runner loss is not guaranteed cleanup or upload; the outer CI timeout bounds the job. + +### 3. Memory safety + +Adversarial question: does the delta create an unsafe access, or encourage a false claim that clean guests establish existing assembly soundness? + +| Item | Outcome and justification | +|---|---| +| S12 — New unsafe meets policy | **N/A:** no shipped unsafe, Rust or assembly delta, safety-reasoning modification or new audit entry. | +| S13 — Safety invariants hold at every call site | **Flagged, existing HIGH T-038 only:** console_write's input-only x2 conflicts with BSP resume writes; this unchanged excluded defect is not resolved by a passing smoke. | +| S14 — No uninitialized memory exposed | **OK for delta:** orchestration adds no kernel buffer or memory initialization operation, and diagnostics introduce no memory-dump API. | +| S15 — No use-after-free; raw pointer lifetime justified | **N/A:** no raw pointer, allocator or runtime ownership changes. | +| S16 — No mutable aliasing violations | **N/A:** no kernel references, pointer aliasing or synchronization changes. | + +Read-only source inspection confirms `in("x2") buf.len() as u64` in `userland/tyrne-user/src/lib.rs:107` against `f.x2_x3[0] = r.payload[1]` in `bsp-qemu-virt/src/syscall.rs:224`. T-038 remains HIGH. Private text mutations do not become shipped Rust and do not trigger a new unsafe approval. No assertion that unchanged unsafe code is newly safe is made. + +### 4. Kernel-mode discipline + +Adversarial question: can this change newly expose kernel resource exhaustion, an unbounded privileged path or a panic to a task? + +| Item | Outcome and justification | +|---|---| +| S17 — No ISR allocation | **N/A:** no ISR or kernel allocation path changes. | +| S18 — Kernel loops bounded | **N/A to kernel delta:** the existing demo's intentional terminal spin is unchanged; smoke supplies a watchdog and the job has a ten-minute bound. | +| S19 — Critical sections minimized | **N/A:** no scheduler lock, interrupt mask or protected-state lifetime changes. | +| S20 — No new hot-path panic | **OK for delta:** new error paths are host process failures; shipped kernel panic behavior is unchanged. | +| MP-1 — Allocation exhaustion returns typed errors, never panics | **N/A:** kernel allocation/exhaustion contracts are unchanged; host build failure is rejected rather than accepted as an intended guest negative. | + +Fixture and variant lists are finite. Individual Cargo builds have no separate standalone harness timeout, but CI supplies the enclosing ten-minute timeout. Log memory/disk scales with trusted guest output; this review does not claim a malicious-host denial-of-service defense, SMP correctness or hardware coverage. + +### 5. Cryptography + +Adversarial question: are new secret-dependent operations or weak security primitives introduced through provenance handling? + +| Item | Outcome and justification | +|---|---| +| S21 — Reviewed algorithms, no homemade crypto | **OK for delta:** Python stdlib SHA-256 hashes the smoke script for diagnostics; no custom crypto or authenticity claim is introduced. | +| S22 — Keys absent from logs/errors/Debug | **N/A:** no key material or cryptographic key operation is added. | +| S23 — Constant-time comparisons where needed | **N/A:** marker, profile and anchor comparisons concern public test data. | +| S24 — Acceptable randomness | **N/A to crypto:** exclusive host temporary directories are not kernel randomness, keys or security tokens. | +| S25 — Correct nonce/IV/salt usage | **N/A:** no encryption protocol, nonce, IV or salt is introduced. | + +Source hashes, recorded SHAs and artifact metadata aid diagnosis; they do not authenticate a hostile compiler, source tree or runner. + +### 6. Secrets and logging + +Adversarial question: could the always-upload path disclose credentials or collect unrelated private files? + +| Item | Outcome and justification | +|---|---| +| S26 — No secrets in diagnostics | **OK for reviewed source/evidence:** uploads select one dedicated runner-temp evidence directory containing public trace/build/provenance output, not home, the checkout, environment dump or credential store. | +| S27 — Sensitive Debug redacts or is absent | **N/A:** no security-sensitive type formatter changes. | + +Read production raw traces, pipeline output, metadata and actual probe traces. They expose demo labels, virtual/physical addresses, versions and CI paths, not new capability-token/key contents. No secret is supplied to the new job. Artifact upload is `if: always()`, errors on missing files, retains 14 days, and introduces no token-scope widening. The new pipeline trace is correctly labeled synthetic and retained as combined output; its private raw scratch file is intentionally cleaned. Early failures preserve whatever evidence exists, but cancellation/runner loss may prevent upload. Malicious build code could print anything available to it; unchanged no-secrets/read-only CI is the relevant boundary. + +### 7. Dependencies + +Adversarial question: is new executable trust pinned and confined to the build/test layer? + +| Item | Outcome and justification | +|---|---| +| S28 — New dependencies evaluated under policy | **OK:** new upload action is pinned to full SHA `cf430e030ddbb5b0abf93d22962f4752f3646cd9`; QEMU is explicitly authorized Ubuntu tooling; Python uses stdlib, with no new Cargo or pip package. | +| S29 — Trust category understood | **OK:** QEMU, Python and Actions are host/CI execution dependencies, not new kernel-linked code; checkout/cache full SHA pins and credential nonpersistence are retained. | +| S30 — cargo-vet trust decisions updated | **N/A:** Rust lockfile, dependency graph and cargo-vet trust decisions are unchanged. | + +The canonical Round 1 security report independently checked the official upload-action tag/source; that is supplied provenance here, not a repeated lookup by this reviewer. This pass verifies the immutable pin and unchanged action identity, not a full audit of its bundled JavaScript. Ubuntu/QEMU are rolling packages, with actual versions recorded; no bit-for-bit stable host claim is made. Each embedded guest image is rebuilt from project source with the pinned Rust/LLVM toolchain. No proprietary guest blob is added. + +### 8. Threat-model impact + +Adversarial question: does a successful gate claim stronger runtime protection than the experiment proves? + +| Item | Outcome and justification | +|---|---| +| S31 — Reconciled with security-model.md | **OK:** the developer-error/boot-assurance boundary is strengthened, and the prior CI failure-masking defect is fixed; runtime capability, MMU, IPC and DMA assumptions are unchanged. | +| S32 — Model shift documented or follow-up scheduled | **N/A:** no new runtime principal, authority, protection or adversary class is introduced, so no threat-model amendment is required. | + +Accepted ADR-0040 governs this approved development sequence; ADR-0031/0039 govern profile behavior and source-built userland. Marker checks are not cryptographic attestation, exhaustive syscall/security proof, exact SVC-count verification or proof of zero exit status. Real private mutations cover omission/completion/forbidden greeting, while fault classes remain synthetic. Existing T-038 is not downgraded. + +Live required-check registration is intentionally sequenced after corrected hosted green and both completed fresh review rounds. At this report it is still pending, as is the final maintainer PR; T-034 remains In Review and its corresponding checkboxes remain unchecked. The future exact context is `QEMU debug + release smoke (nightly)` with existing protections/app bindings preserved. This pending authorized step is not a false Done claim. No live-policy certification is implied here. + +### Architectural principles P1–P12 + +| Principle | Outcome and justification | +|---|---| +| P1 — No ambient authority | **OK for delta:** no runtime grant or repository-token permission widening. | +| P2 — Smallest defensible TCB | **OK:** added code is host tooling; shipped kernel code is unchanged. | +| P3 — Drivers in userspace | **N/A:** no subsystem placement change. | +| P4 — Capability checks at trust boundaries | **OK for runtime delta:** existing checks unchanged; changed CI status boundary now preserves rejection. | +| P5 — Rust and disciplined assembly | **OK for delta:** Python/shell are host-only and no new assembly soundness approval is claimed. | +| P6 — HAL boundary | **N/A:** no architecture-specific kernel/HAL interface change. | +| P7 — No proprietary blobs | **OK:** source-built userland images and disposable private variants only. | +| P8 — Decisions recorded | **OK:** Accepted ADR-0040 authorizes scope; no conflicting architectural decision introduced. | +| P9 — English | **OK:** changed repository prose, code comments and diagnostics are English. | +| P10 — Mermaid | **N/A:** no diagram introduced. | +| P11 — Pinned/reproducible builds | **OK for delta:** nightly/lockfile unchanged, actions fully pinned, profile/image ordering and provenance explicit; host package drift not hidden. | +| P12 — No half-finished main | **OK for scoped development:** gate defect fixed, source reviewed and hosted-green; final registration/PR/promotion remain honestly pending under approved sequencing. | + +### Executed evidence and limitations + +**Own fresh execution:** `tools/test-smoke-gates.sh --real --artifact-dir /tmp/tyrne-b21-t034-round2-security-real` exited 0, all **23/23** cases passed with `completed:true`: 20 synthetic fixtures and three actual privately built/booted kernels. Results bind clean documentation tip `9092581f1363c19cd3943c4d3a95a0d0c8634540` and smoke SHA-256 `a48aada8f9b1b1173f9be73c3a2715b9bf3932246bc7457bcc1296f65abddba8`; executable source is unchanged from `97a6c83`.

The exact guard sensitivity/accidental-failure matrix is described above. `git diff --check 07449f1..9092581` passed, and checked tracked worktree was clean. No full host-test, Miri or broad lint rerun was necessary for this host-only source correction; corrected hosted run supplies those job conclusions. + +**Supplied corrected hosted evidence independently inspected:** `/tmp/tyrne-b21-step6/corrected-hosted-artifact/`, `corrected-hosted-run.json` and `corrected-hosted-qemu.log`. [Run 38183696397](https://github.com/HodeTech/Tyrne/actions/runs/38183696397) binds exact source `97a6c836e6180b2e61f1242560977ee21995258d`; all six recorded jobs conclude success. Guard output contains actual missing greeting/exit diagnostics; effective explicit Bash/pipefail is recorded for the guard and both production steps. Both raw production traces show EL0 SVC activity: debug exact greeting/exit/completion; release exit/completion without greeting; neither contains a listed fault.

Successful artifact upload is part of the supplied hosted evidence. + +The initial source6450005 hosted run and both Round 1 reports remain historical evidence, not proof of corrected pipeline failure propagation. No deliberately broken hosted commit was pushed; controlled synthetic rejection plus the effective shell and local broken-shell sensitivity establish the corrected caller boundary.

Recovered truncated prerequisite reads in smaller ranges. Reviewed prior T-034 security findings and corrected Round 2 failure-propagation analysis, T-037's target-boundary review and its explicit T-038 exclusion, and current T-035/T-036 scope/evidence records. ADR-0040's Accepted D1–D4 govern this implementation; this is not a re-audit of historical kernel implementations. + +No repository writes, branch changes, commits, live policy operations or live administrative apply—including no-op apply—were performed by this reviewer. All executable experiments used a private `git archive` of the immutable tip at `/tmp/tyrne-b21-t035-security-r1`; all additional files are under `/tmp`. The transport failure tests mock subprocess execution. No fixture can reach the actual GitHub API. Official public GitHub documentation was read to verify API/shell semantics. Parent-downloaded hosted artifacts and parent-produced live export/no-op logs were inspected locally and remain attributed to the parent. + +## 1. Capability correctness + +| Item | Adversarial question | Outcome and justification | +|---|---|---| +| S01 — Every privileged operation requires authority | Can an unprivileged caller change main protection? | **OK for host boundary; N/A to runtime capabilities.** The sole mutation requires explicit `apply` and GitHub repository Administration write authority; export/check contain only policy reads, and no new kernel operation exists. | +| S02 — Narrowest sufficient authority | Can supplied input redirect or widen the administrative operation? | **OK.** Hostname, repository, main branch and endpoint are fixed; only status-check protection is PATCHed, and CI remains `contents: read` with nonpersisted checkout credentials and no admin secret. | +| S03 — Checks precede observable privileged effects | Can malformed policy, stale state or forged proof reach PATCH? | **OK.** Full local validation, expected-current equality, add-only comparison, full-SHA/app-bound green proof and a final full live comparison precede mutation; independent negative cases reached zero fake writes. | +| S04 — Transfer is move-only | Can this change clone a runtime capability during transfer? | **N/A.** No runtime capability representation, transfer or ownership operation changes. | +| S05 — Duplication needs explicit authority | Can the tool mint duplicate capability rights? | **N/A.** No capability duplication operation or right is introduced; GitHub authentication stays with the maintainer's existing local CLI. | +| S06 — Revocation is atomic | Can a capability be half-revoked? | **N/A.** No runtime revocation changes; REST policy reconciliation is deliberately non-atomic and is analyzed separately below. | + +The administrative tool is a guard against unsafe reconciliation, not a sandbox against someone already controlling the maintainer's host, CLI executable or admin token. CI environment checks refuse even false-valued `CI`, `GITHUB_ACTIONS`, `GITHUB_RUN_ID` or `RUNNER_ENVIRONMENT` markers before API access. A privileged host operator can use GitHub directly; environment-variable refusal does not claim to remove that authority. + +## 2. Trust boundaries + +| Item | Adversarial question | Outcome and justification | +|---|---|---| +| S07 — Validate userspace inputs before kernel use | Can malformed syscall input gain a new privileged route? | **N/A to runtime; OK for changed host analog.** No syscall parser changes; JSON definitions and remote policy are validated before administrative mutation. | +| S08 — User pointers require validated mappings | Can supplied addresses be dereferenced by the kernel? | **N/A.** No user pointer, mapping or privileged memory-access path changes. | +| S09 — Range-check user buffer lengths | Can an oversized user length bypass mapping bounds? | **N/A.** No user buffer or length consumer changes; remote check evidence separately rejects incomplete or over-100 result sets. | +| S10 — Typed parsing of messages | Can unstructured input silently replace policy? | **OK for host analog; N/A to IPC.** Duplicate JSON object keys, unknown fields, missing required fields and wrong exact types are rejected; status contexts must agree with unique app-bound checks. | +| S11 — IPC cannot transfer excess authority | Can the sender grant rights it never held? | **N/A.** No IPC operation, sender/receiver authority or transfer behavior changes. | + +**Administrative input boundary — OK.** The definition preserves all nine REST booleans, review flags/count, null restrictions, strict checking and every existing context/app pair. Unknown fields fail closed rather than being discarded. URL metadata is the only general response-only metadata removed and must be a string. Omitted REST restrictions normalize to null only within the explicitly supported baseline, while the GraphQL rule separately requires no push restriction or actors. GraphQL-only `requiresApprovingReviews:true`, deployment-off/empty environments and four zero actor counts are captured. Rendering the supported GraphQL rule before equality avoids Python's bool/int equivalence. New/inherited rulesets cause refusal; GitHub documents `includes_parents` defaulting to true for this endpoint. [Repository rules API](https://docs.github.com/en/rest/repos/rules#get-all-repository-rulesets). + +**Remote proof boundary — OK.** `--verified-sha` must be a full lowercase 40-character SHA, including on a no-op. Each new check requires exactly one returned name match, the same full head SHA, completed/success and an exactly typed matching app ID. An explicit total/list-length agreement and 100-run ceiling reject truncation rather than guessing across pages; duplicate matches reject even if one succeeds. Existing checks cannot be removed or rebound. The proof is for the maintainer-selected commit; it is not a claim that an arbitrary caller-supplied SHA is the current branch tip or that app identity attests to trusted workflow content. + +**Transport boundary — OK.** `gh` receives an argv list, fixed `--hostname github.com`, version header and method, with JSON through stdin; no shell interpolation, input-driven endpoint or token argument is added. Export/check's GraphQL POST executes a constant `query`, not a mutation. The only policy write is PATCH to `/required_status_checks` with strict/checks; no whole-protection replacement, deletion, ruleset change or rollback exists. Official endpoint documentation identifies the narrow PATCH and its Administration-write permission. [Status-check protection API](https://docs.github.com/en/rest/branches/branch-protection#update-status-check-protection). + +**Concurrent administrator boundary — documented limitation, not atomicity proof.** The complete REST/GraphQL/ruleset policy is re-read immediately before PATCH and again afterward. A concurrent change after the last read can still be overwritten within the status-check object, and separate REST/GraphQL reads are not an atomic snapshot. Read-back may detect divergence but cannot detect a concurrent check that was added and overwritten in the race window. `docs/guides/ci.md:192` explicitly states the lack of documented atomic conditional update, requires administrative coordination, and forbids automatic rollback. This limitation is accepted within the requested local maintenance model; no CAS guarantee is claimed or inferred. + +**Performance result boundary — OK for informational reporting.** Explicit job-level Bash supplies pipefail, so `tee` cannot make a failed harness green. GitHub documents this explicit-shell behavior. [Workflow syntax](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax#jobsjob_iddefaultsrun). The report path must match the fixed date/context shape before copying. The job has no PR trigger, required-check registration, timing threshold or `continue-on-error`. A failed measurement is a visibly failed informational workflow. The inherited harness accepts its documented minimum-valid fraction and reports requested/valid/failed counts; a partial sample set is not mislabeled 20 successful runs. Guest timing text is diagnostic input from the source-built guest, not cryptographic attestation against hostile source/QEMU/compiler. + +## 3. Memory safety + +| Item | Adversarial question | Outcome and justification | +|---|---|---| +| S12 — New unsafe meets policy | Can new unsafe escape a SAFETY/audit review? | **N/A.** No production Rust/assembly or unsafe region changes; Python and shell are host tooling. | +| S13 — Safety invariants hold for all callers | Can passing CI be mistaken for proof of the known assembly contract? | **Flagged — existing HIGH T-038, excluded and unchanged.** `console_write` still declares x2 input-only while BSP return handling overwrites saved x2; this security approval does not endorse that invariant. | +| S14 — No uninitialized memory exposed | Can newly exposed buffers disclose uninitialized memory? | **N/A to runtime; OK for delta.** No kernel buffer initialization or memory-dump API changes; new metadata is public host/run provenance. | +| S15 — No use-after-free | Can new raw-pointer lifetime changes create stale access? | **N/A.** No raw pointer, allocation lifetime or runtime ownership change. | +| S16 — No mutable aliasing violations | Can the change create concurrent mutable references? | **N/A.** No Rust references, aliasing operation or synchronization contract changes. | + +Read-only source inspection at the immutable tip confirms `userland/tyrne-user/src/lib.rs:107` has `in("x2") buf.len() as u64`, while `bsp-qemu-virt/src/syscall.rs:224` writes `f.x2_x3[0] = r.payload[1]`. T-038 remains HIGH. No unsafe audit entry or new unsafe approval is warranted for T-035, and existing tests do not resolve the mismatch. + +## 4. Kernel-mode discipline + +| Item | Adversarial question | Outcome and justification | +|---|---|---| +| S17 — No ISR allocation | Can an interrupt force a newly allocating path? | **N/A.** No ISR or runtime allocation path changes. | +| S18 — No unbounded kernel loops | Can an attacker newly stall the kernel? | **N/A to kernel delta.** Kernel loops are unchanged; performance measurement retains the per-run watchdog and the workflow adds a ten-minute outer bound. | +| S19 — Minimize critical sections | Can a caller extend lock/IRQ-disabled time? | **N/A.** No scheduler state, lock or critical-section change. | +| S20 — No new hot-path kernel panic | Can a new input cause a runtime panic? | **OK for delta.** New error paths are host validation/process failures; no shipped kernel hot path changes. | +| MP-1 — Typed allocation-exhaustion errors | Can allocation exhaustion now panic the kernel? | **N/A.** No kernel allocator or exhaustion behavior changes; host resource failures do not imply kernel safety. | + +The admin tool bounds each `gh` call to 30 seconds and does not retry writes. It is not a general defense against arbitrarily huge local files or a compromised upstream service exhausting Python's memory. Those are trusted-maintainer-host availability assumptions, not new kernel resource exposure. The performance job runs 20 iterations with five-second guest watchdogs and a ten-minute workflow bound; cancellation/runner loss may prevent artifact delivery despite `always()`. + +## 5. Cryptography + +| Item | Adversarial question | Outcome and justification | +|---|---|---| +| S21 — Reviewed primitives, no homemade crypto | Can a novel algorithm forge authority? | **N/A.** No cryptographic primitive or protocol is introduced; HTTPS/authentication remains GitHub CLI infrastructure. | +| S22 — Keys absent from logs/errors/Debug | Can API failure expose authentication material? | **OK for credential handling.** `gh` stderr is captured and never echoed; independent failed-process and timeout fixtures kept a secret sentinel out of stdout/stderr. | +| S23 — Constant-time comparisons where relevant | Can comparison timing disclose a secret? | **N/A.** Policy names, booleans, app IDs and source SHAs are public metadata, not secret values. | +| S24 — Acceptable randomness | Can weak random generation mint predictable secrets? | **N/A.** No random token, key or nonce generation changes. | +| S25 — Correct nonce/IV/salt contract | Can a replay misuse newly introduced nonce state? | **N/A.** No encryption, nonce, IV or salt state is introduced. | + +Full source SHAs bind evidence to a commit; they are not signatures or a guarantee that the selected runner/toolchain is uncompromised. + +## 6. Secrets and logging + +| Item | Adversarial question | Outcome and justification | +|---|---|---| +| S26 — No secrets in diagnostics | Can command errors or artifact selection collect credentials? | **OK for reviewed boundary.** Generic nonzero `gh` failures suppress stderr; no token is passed in argv; workflow artifacts select only the dedicated runner-temp evidence directory, with no environment/home/cache dump. | +| S27 — Sensitive Debug redacts or is absent | Can a formatter print key/capability internals? | **N/A.** No Rust Debug implementation or sensitive type is introduced; the script does not format captured credential-bearing stderr. | + +The workflow records source SHA, run/attempt, UTC interval, Rust/toolchain, QEMU, host details and harness output. The inspected hosted artifact contains those public diagnostic fields and the generated report. Artifact upload runs on success/failure, errors when evidence is missing and retains 14 days; it does not grant repo write permission. No admin secret is introduced into CI. A malicious checkout/build process could print data already available to its runner; read-only token/no admin secret and checkout credential nonpersistence are the relevant controls, not log filtering of arbitrary hostile programs. + +## 7. Dependencies + +| Item | Adversarial question | Outcome and justification | +|---|---|---| +| S28 — New dependencies evaluated under policy | Can new third-party code silently enter the kernel? | **OK for host additions; N/A to Cargo additions.** Scripts use Python stdlib and existing shell/Rust/QEMU tooling; actions use full immutable SHAs and no manifest/lockfile dependency is added. | +| S29 — Trust category understood | Can build tooling become runtime TCB code? | **OK.** `gh`, Python, Bash, QEMU and Actions remain maintainer/CI tools; none is linked into the guest kernel. | +| S30 — cargo-vet trust decisions updated | Can a new crate bypass trust review? | **N/A.** Cargo graph/lockfile and cargo-vet decisions are unchanged. | + +Checkout `11bd71901bbe5b1630ceea73d27597364c9af683`, cache `5a3ec84eff668545956fd18022155c47e93e2684`, and upload `cf430e030ddbb5b0abf93d22962f4752f3646cd9` match already-reviewed project pins. This pass verifies the immutable configuration, not a fresh full audit of bundled action JavaScript; prior T-034 security review records official upload-tag/source provenance. Rust remains pinned to nightly-2026-01-15. Performance cache keys and restore prefixes include OS, architecture, performance namespace and toolchain, preventing accidental cross-architecture cache sharing. Normal Cargo/source/compiler/cache trust remains; this is not a hermetic cache attestation scheme. Ubuntu and apt QEMU roll, so their observed versions are recorded rather than claimed immutable. Userland and kernel are built in the required order from source; no proprietary blob is added. + +## 8. Threat-model impact + +| Item | Adversarial question | Outcome and justification | +|---|---|---| +| S31 — Reconciled with security-model.md | Can new authority or misleading assurance weaken a documented boundary? | **OK for T-035 delta.** The new admin surface is local, fixed-target and additive; CI remains unprivileged, and performance output is explicitly informational. The inherited T-036 reliability hold below remains visible. | +| S32 — Model shift documented or tracked | Is a new adversary or security promise silently introduced? | **N/A to runtime model change.** No runtime principal, capability, IPC/MMU/DMA boundary or protection claim changes; ADR-0040 and the CI guide document the host administration/scheduling scope and limits. | + +### Findings and integration hold + +**No new actionable security finding in the T-035 delta.** The JSON baseline and supplied live export compare equal, including all six checks with app ID 15368, strict true, reviews/REST policy, GraphQL PR-review enabled/deployment disabled/no actors, and empty rulesets. The parent-produced apply log says `PASS: live policy matches; no write needed`; this reviewer did not invoke it or certify a policy mutation. + +**Corroborated inherited T-036 integration issue — not cleared by this security verdict.** Parent supplied `/tmp/tyrne-b21-step7/registration-tip-failure.log` from hosted run 38186028266 at the prior registration tip. It shows the deliberately restored arch-only hello build failing with `error: unwinding panics are not supported without std`, followed by the harness's refusal because it expected only `error[E0152]: found duplicate lang item panic_impl`. At the immutable reviewed tip, `tools/test-ci-gates.sh:74` still permits only the latter diagnostic after restoring exactly six hello target predicates. Cargo's all-targets competition can surface either genuine symptom first. This is a verified false-negative/reliability problem in the inherited required gate, not a newly demonstrated privilege bypass or false-green security result. The paired code pass appropriately holds integration until the correction is reviewed. A fix must retain exact mutation preconditions and reject unrelated compiler/tool failures; widening acceptance to any nonzero compiler exit would lose the intended negative control. Subsequent edits are outside this immutable review and require fresh Round 2. + +The historical earlier reviews remain scoped to their exact commits and observations. One later green run does not disprove a race observed in another run. Existing HIGH T-038 is separately retained and is not folded into, fixed by, or downgraded by this host diagnostic issue. + +### Architectural principles P1–P12 + +| Principle | Outcome and justification | +|---|---| +| P1 — No ambient authority | **OK for delta.** No runtime grants; admin action requires explicit local command and external GitHub authority, absent from CI. | +| P2 — Smallest defensible TCB | **OK.** Host-only tooling; shipped kernel TCB unchanged. | +| P3 — Drivers in userspace | **N/A.** No driver/service placement change. | +| P4 — Checks at trust boundaries | **OK for changed boundary.** Fail-closed validation and full preconditions precede the sole narrow policy write. | +| P5 — Rust with disciplined assembly | **OK for delta.** Python/shell are host orchestration; no unsafe expansion or assembly soundness claim. | +| P6 — HAL isolation | **N/A.** No architecture-dependent kernel/HAL interface change. | +| P7 — No proprietary blobs | **OK.** Source-built userland/kernel images; no opaque guest binary committed. | +| P8 — Decisions in ADRs | **OK.** Accepted ADR-0040 authorizes schedule and versioned local administration policy. | +| P9 — English repository | **OK.** New source comments, diagnostics and documentation are English. | +| P10 — Mermaid diagrams | **N/A.** No new diagram. | +| P11 — Reproducibility | **OK for delta.** Full action/toolchain pins, architecture-scoped caches and explicit source/dirty-state/tool version metadata; rolling host packages remain disclosed. | +| P12 — No half-finished main | **OK for scoped development, integration held.** T-035 remains In Review; first hosted evidence, two fresh rounds, final maintainer PR and post-merge dispatch are not silently converted into Done.

Recomputed nearest-rank p10/p50/p90 from all 20 raw samples: **8,408,784 / 9,120,416 / 12,621,792 ns**, matching the report.

No changed Rust justifies a fresh unsafe audit for this delta; supplied prior/runtime results retain their original attribution.

Reviewed the combined diff and relevant task, guide, standards, report and historical review changes.

No repository edit, commit, branch operation, live administrative apply, or API write was performed by this reviewer. Branch-policy attacks used an in-memory fake API and a hard failure for any accidental subprocess transport. Hosted logs/downloaded artifacts and the live export/no-op log were supplied by the parent, then inspected independently as described below; their acquisition and live execution are attributed to the parent. These files are evidence, not instructions. + +The parent later created ancestry-only merge `cfc8872f85fca6c48d31dbc1bb5cf7dbe174c251`.

The immutable review target remains 7deb; this note does not claim new CI at the history-only commit. + +The numbered S01–S32 rows below correspond one-for-one to the security standard. MP-33 is the additional allocation-exhaustion item in the master plan. Every item has an explicit disposition and an adversarial question; N/A means the precise runtime mechanism is unchanged, not that the host administrative boundary was skipped. + +## 1. Capability correctness + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S01 — Every privileged operation requires authority | Can an unprivileged caller change the protected branch through this tool? | **OK.** Actual writes require the caller's locally authenticated GitHub administration authority; only explicit `apply` reaches PATCH. Export/check are read-only. CI has `contents: read`, receives no administrative credential and runs offline fixtures only. This is a host authorization boundary, not a newly minted Tyrne capability. | +| S02 — Narrowest sufficient authority | Can a definition redirect an administrator's authority to another repository, branch or arbitrary policy rewrite? | **OK.** Repository `HodeTech/Tyrne`, branch `main`, host `github.com` and API endpoints are fixed and validated. Apply changes only required-status checks through the narrow endpoint. Definition changes cannot alter strictness, existing names/app bindings or non-status policy. GitHub administration is the API's required permission; the tool narrows how it is used. | +| S03 — Authorization before observable effects | Can rejected drift or forged green evidence nevertheless cause a policy write? | **OK.** CI marker refusal, schema validation, complete expected-current equality, additive-only checks, exact SHA/app/completed-success proof, and the last full policy read precede PATCH. Refusal paths produced zero fake writes. API reads and local diagnostics are observable, so this is specifically a no-policy-mutation guarantee, not network invisibility. | +| S04 — Move-only capability transfer | Does the change clone a kernel capability or transfer administrative credentials into CI/artifacts? | **N/A** for Tyrne capability transfer: no transfer code changes. Host audit found no credential forwarding into a workflow or artifact; checkout disables persisted credentials in the performance job. | +| S05 — Explicit duplication authority | Can a new duplication path manufacture a capability? | **N/A.** No capability duplication operation, table, handle encoding or rights change exists in the delta. Reusing ordinary local `gh` authentication is an administrator-controlled host operation. | +| S06 — Atomic revocation | Does the change claim atomicity while removing rights in several stages? | **N/A** for capability revocation: no revocation path changes. Administrative reconciliation is explicitly non-atomic and cannot remove existing checks; the separate administrator race is analyzed under axis 8 rather than mislabeled atomic revocation. | + +The local tool is a guardrail for a trusted administrator, not a sandbox against a malicious administrator who can edit the script, unset CI variables or call GitHub directly. GitHub documents administration-write permission and the narrow status-check PATCH, including explicit app binding. [GitHub status-check protection API](https://docs.github.com/en/rest/branches/branch-protection#update-status-check-protection). + +## 2. Trust boundaries + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S07 — Validate userspace-to-kernel input | Can malformed input reach a changed kernel entry point, or can analogous malformed policy input authorize a write? | **N/A** for the syscall boundary, which is unchanged. **OK** for the host analogue: exact key sets/types, supported values, duplicate-key rejection, full normalized equality and remote evidence validation fail closed before mutation. Null/scalar/error-envelope attacks were rejected without writes. | +| S08 — Validate user pointers before kernel dereference | Can a supplied pointer or path become a kernel dereference or shell command? | **N/A.** No user-pointer code changes. The host API uses an argv list and stdin JSON, not shell evaluation; fixed endpoint construction and full lowercase SHA validation reject shell-shaped SHA input. | +| S09 — Bound user lengths against mapped regions | Can a length overrun a new mapped buffer or allow incomplete remote evidence? | **N/A** for mapped buffers. **OK** for check evidence completeness: exact integer total count, at most 100 entries, and equality to list length reject truncation/pagination rather than trusting a partial successful result. No new byte-copy length exists. | +| S10 — Parse messages into typed structures | Can unknown/missing/duplicate JSON fields, bool-as-int values or a near-match diagnostic be treated as valid evidence? | **OK** for the relevant host boundary. JSON duplicate keys and unsupported policy keys fail; booleans/integers are checked exactly where authority matters; GraphQL baseline comparison preserves type distinctions. The ARM assertion requires exit 101 and a full exact line from one of two observed diagnostics. Independent whitespace/prefix/suffix/ANSI lookalikes fail. No raw userspace message parser changes. | +| S11 — IPC transfers no excess authority | Can a sender obtain additional cross-task rights through this change? | **N/A.** IPC endpoints, send/receive, transfer semantics and kernel call paths are byte-unchanged. The administrative analogue preserves every existing name/app binding and cannot weaken non-status policy. | + +The effective classic policy is read through both REST and a fixed read-only GraphQL query. GraphQL covers review enablement, deployments and actor allowances omitted from the supported REST view. Unsupported nonempty extensions and any repository/inherited ruleset stop reconciliation. Empty rulesets are the only supported baseline, so the first page containing any rule is sufficient to refuse; it never accepts a partial nonempty list. GitHub documents inherited rulesets as included by default. [Repository rulesets API](https://docs.github.com/en/rest/repos/rules#get-all-repository-rulesets). + +For new check registration, a local fabricated result file cannot supply the green proof: the tool queries check runs at the exact supplied 40-character SHA and requires exactly one matching name with the configured app, completed status and successful conclusion. Duplicates, missing results, failure/neutral/skipped conclusions, app mismatches and incomplete lists fail. This proves the requested check at that SHA; it does not prove the caller selected the current branch head, authenticate arbitrary workflow semantics, or eliminate the need to review the definition and chosen source. + +## 3. Memory safety + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S12 — New unsafe meets policy | Is a changed unsafe site missing justification, audit registration or security sign-off? | **N/A.** The 23-file delta has no shipped Rust/assembly or unsafe change. Python and shell host tools require boundary review, but do not receive invented Rust unsafe entries. | +| S13 — Safety invariants hold for every caller | Does a new caller broaden an existing unsafe contract, or does a green gate wrongly clear known UB? | **N/A** for changed callers: none. **Flagged — existing excluded HIGH remains:** T-038 / UNSAFE-2026-0033 x2 syscall-clobber issue is not fixed or downgraded by this tooling review. Successful tests and probe diagnostics do not validate that assembly's contract. | +| S14 — No uninitialized memory exposure | Can a partially initialized kernel buffer become visible? | **N/A.** No buffer initialization or kernel output source changes. Host metadata records explicit dirty/clean/unknown state; a failure to query source state is not relabeled clean. | +| S15 — No use-after-free | Does a changed raw pointer outlive its owner, or can the probe destroy source through cleanup? | **N/A** for raw pointers. Host cleanup is bounded to a newly created private temporary directory, with quoted paths and an EXIT trap; offline cases check source hashes and removal after success, rejection and copy failure. No repository source deletion occurs. | +| S16 — No aliasing violation | Can overlapping mutable references cross a switch or concurrent kernel boundary? | **N/A.** No references, context switches or runtime memory ownership change. Probe mutations and Cargo output are isolated to their own temporary copy/target; source-preservation assertions pass. | + +No unsafe audit entry is created, amended or second-signed by this review. The audit applicability determination is based on the complete diff, not an assumption that Python/shell changes can never be security-sensitive. + +## 4. Kernel-mode discipline + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S17 — No allocation in ISRs | Does the measurement/reporting path allocate from an interrupt handler? | **N/A.** Reporting runs on the host after unchanged guest output; no ISR code changes. | +| S18 — No unbounded kernel loops | Can a new loop stall privileged guest execution or consume unlimited hosted runtime? | **N/A** for kernel loops. Host exposure is bounded: 20 requested measurement iterations with a five-second per-run watchdog, a ten-minute performance job, existing ARM job bound, finite API work and a 30-second subprocess API timeout. This is not an SLA for GitHub scheduling. | +| S19 — Minimize critical sections | Can external API waits or report formatting hold a kernel lock? | **N/A.** All added administration/reporting work is host-side; kernel locks, IRQ masking and scheduler critical sections are unchanged. | +| S20 — No new hot-path kernel panic | Can malformed host input or the diagnostic fallback introduce a production panic? | **N/A.** The intentional no_std/panic-handler regression exists only in the disposable compiler-probe copy. The shipped six cfg predicates, build script and syscall shim stay unchanged. Expected compiler failure is separate from production failure. | +| MP-33 — Allocation exhaustion returns typed errors, not panics | Can a new kernel allocation exhaust memory and panic? | **N/A.** No kernel allocator, arena capacity or allocation path changes. Host memory/disk/tool failures yield failing commands and cannot bypass the pre-write policy checks. This review makes no general claim that Python allocation is bounded against hostile local files. | + +The ARM fix retains the exact `cargo clippy --workspace --exclude tyrne-bsp-qemu-virt --all-targets -- -D warnings` command. It still requires a native aarch64 Rust host, precisely six matching predicates, and only replaces those predicates in the private hello source. Its two accepted full lines correspond to the test harness's duplicate panic handler and the normal no_std binary's unwind rejection. Cargo's all-target compilation may expose either first. Exit 0, tool failures and unrelated compiler errors are not accepted. Printing the actual observed class makes the assertion auditable. + +The performance logging pipeline uses explicit Bash, preserving failure through `tee`; the independently executed fixture checks this failure path. GitHub's explicit Bash command includes `-eo pipefail`. [Workflow shell syntax](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax#jobsjob_iddefaultsrun). + +## 5. Cryptography + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S21 — Reviewed cryptographic primitives | Is a home-grown cipher, hash, signature or protocol introduced? | **N/A.** No cryptographic implementation or protocol is added. Commit/action SHA identifiers and artifact SHA-256 evidence are provenance references, not a new cryptosystem. | +| S22 — Keys absent from logs/errors/Debug | Can a newly handled cryptographic key leak? | **N/A** for cryptographic key management: none is introduced. GitHub credential handling is separately applicable and assessed in S26. | +| S23 — Constant-time sensitive comparisons | Does a new comparison reveal secret-dependent timing? | **N/A.** Equality checks compare public policy, source identifiers and check evidence; no secret equality or cryptographic decision is implemented. | +| S24 — Acceptable randomness | Can predictable randomness compromise a new secret or protocol? | **N/A.** No security nonce/key generator is added. Host temporary directories use existing platform temporary-directory facilities, not invented secret-generation code. | +| S25 — Correct nonce/IV/salt contracts | Can nonce reuse or invalid initialization break encryption/authentication? | **N/A.** No encryption, nonce, IV or salt handling exists in the delta. | + +## 6. Secrets and logging + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S26 — No secrets in diagnostic channels | Can gh stderr, a token or repository credential be copied into logs, JSON or artifacts? | **OK.** The tool relies on existing local gh authentication without printing credentials; failed gh stderr is captured and replaced by a generic failure. Transport fixtures pin redaction. Export/check differences contain policy values, not tokens. Performance artifacts collect explicit run/source/toolchain/QEMU/host/output files from a dedicated evidence directory, not the workspace or credential store. | +| S27 — Security-sensitive Debug redacted/absent | Does a new Debug/representation expose capability or credential bytes? | **N/A** for Rust Debug implementations: none change. **OK** for analogous host representations: no credential-bearing type is serialized or printed; diagnostic fixtures exercise transport failure secrecy. | + +Hostnames, source SHA, public run identifiers, toolchain paths and guest console output are intentionally diagnostic metadata. Their publication is appropriate to this public repository's CI contract; no general promise of arbitrary-output secret scrubbing is made. Trusted build tools and reviewed guest output remain assumptions. Read-only `contents` permission still permits the platform's artifact/cache mechanisms; those are bounded CI evidence facilities, not branch-administration authority. + +## 7. Dependencies + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S28 — Dependency addition policy | Does the change silently introduce an unaudited Rust dependency? | **OK.** No Cargo manifest/lock dependency change; Python uses the standard library and shell tools already used by the project. New workflow references reuse full-SHA-pinned actions. No add-dependency/Cargo trust approval is owed for a nonexistent crate addition. | +| S29 — Trust category understood | Can a build-time service/tool be mistaken for kernel-linked or hermetic trust? | **OK.** GitHub, gh, Python, Bash, pinned Rust/actions, hosted runner packages and QEMU are host/build/evidence trust. No new kernel-linked trust is introduced. ubuntu-latest and apt QEMU can change; actual versions are recorded, and timings are not claimed bit-reproducible across hosts. | +| S30 — cargo-vet updated as needed | Was a changed Rust dependency left without its trust decision? | **N/A.** No external Rust dependency is added/upgraded; the repository's conditional cargo-vet/cargo-audit work remains dormant until an external dependency lands. This does not mean those tools were run here. | + +The performance workflow has schedule Monday 03:17 UTC, manual dispatch and only two exact development push paths (`.github/workflows/performance.yml`, `tools/perf-harness.sh`); no pull-request trigger. It has read-only contents permission, disabled checkout credential persistence, dedicated architecture/toolchain cache identity, timeout/concurrency limits and 14-day artifacts. Package installation remains ordinary hosted provisioning; toolchain/QEMU provenance limits performance comparisons rather than silently becoming an unreviewed release guarantee. + +## 8. Threat-model impact + +| Item | Adversarial question | Disposition and justification | +|---|---|---| +| S31 — Reconciled with security model | Does the new administrative boundary relax runtime capability isolation or conceal a repository-policy weakening? | **OK.** Tyrne's kernel threat model is unchanged. Host supply-chain/administration trust is explicitly added to this review: fixed target, exact supported full policy, no rulesets, no CI admin token, additive-only writes, remote app/SHA proof, final reread and full readback. Existing solo review count 0 and disabled admin enforcement are preserved explicitly, not represented as multi-contributor protection. | +| S32 — Changed threat model documented | Does any new assumption remain hidden or require a missing ADR/update? | **OK.** Accepted ADR-0040 and the CI guide/infrastructure standard document local administration, representability refusal, non-atomic race, coordinated admin changes and no automatic rollback. Performance is informational with no calibrated floor or required check. Runtime security-model.md needs no fictional new kernel boundary; existing deferred runtime risks remain. | + +### Administrative race and applicability limits + +The final full read narrows the race; it is not compare-and-swap. Another administrator can change required checks after that read and before PATCH, and a concurrently added check could be overwritten without the post-write comparison detecting its brief existence. Non-status drift surviving the narrow PATCH is caught by full readback. The API surface does not offer a documented conditional atomic update here, and the guide explicitly requires coordination. This is an accepted, documented limitation of local trusted administration, not a security finding newly introduced by this review. No automatic rollback is correct: rollback could overwrite a third administrator change. A failed post-write verification requires inspection and does not mean no remote mutation occurred. + +Similarly, a sequence of REST/GraphQL/ruleset reads is not one server-side snapshot. API/schema failure or unsupported settings cause refusal. That conservative limitation can make administration unavailable until reviewed adaptation; it cannot silently strip an unmodeled protection field through a broad PUT. The tool does not claim to secure a compromised maintainer account, compromised local executable/PATH, malicious upstream service, or arbitrary edited workflow. + +The informational workflow visibly fails on build/measurement/upload failure; no timing threshold or merge floor exists. Best-effort schedule/dispatch behavior and default-branch registration are documented. Cancellation/runner loss can prevent even `always()` artifact collection; this is evidence availability, not privilege escalation. Post-merge schedule/manual-dispatch and first-main evidence remain pending. + +### P1–P12 applicability + +| Principle | Disposition and reason | +|---|---| +| P1 — No ambient authority | **OK, host analogue.** Explicit local admin authority; no administration token in CI. No Tyrne capability bypass. | +| P2 — Smallest defensible TCB | **OK.** Added code stays in host tooling; kernel TCB is unchanged. The admin tool deliberately supports one repository/branch/policy shape. | +| P3 — Drivers/filesystems/network in userspace | **N/A.** No runtime subsystem placement changes; reporting/admin code is outside the kernel. | +| P4 — Capability checks at every boundary | **OK, host analogue.** Local mode and strict preconditions precede any narrow policy write; kernel capability boundaries unchanged. | +| P5 — Rust-only kernel, justified assembly | **N/A.** No kernel/HAL/service-language or assembly change; Python/Bash are host tools. T-038 remains excluded HIGH. | +| P6 — HAL separation | **N/A.** No HAL, board-specific runtime reference or kernel dependency change. Native host selection is CI orchestration. | +| P7 — No proprietary binary blobs | **OK.** No blob is committed/embedded; the workflow builds userland and kernel from source. Report snapshots are text. | +| P8 — Decisions recorded as ADRs | **OK.** ADR-0040 Accepted before implementation governs schedule/admin choices and the eight-step/two-round procedure. | +| P9 — English repository artifacts | **OK.** Added tooling, documentation, fixture diagnostics and this artifact are English. | +| P10 — Mermaid diagrams | **N/A.** No new diagram; tables and text reports do not introduce an alternate diagram format. | +| P11 — Reproducibility from toolchain up | **OK within scope.** Pinned Rust/actions and unchanged lockfile; full source/tool/host metadata. Timings on rolling hosted infrastructure are explicitly contextual, not reproducible latency guarantees. | +| P12 — No half-finished subsystems on main | **OK for review readiness.** The combined implementation and correction have concrete offline/hosted proof. Work remains In Review on development; final PR/maintainer decision, first merged-main checks and dispatch evidence are not prematurely marked complete. | + +### Independent experiments and supplied evidence + +| Evidence | Observation and attribution | +|---|---| +| Immutable source | Private `git archive` of exact 7deb tip; combined diff inspected. No shipped Rust/assembly changed. Shared development worktree remained clean at verification. | +| Permanent policy suite | Independently ran 27 tests normally and under `python3 -O`: both pass. Covers narrow mutation/readback/no-op, drift, unsupported policy, exact types, green evidence/app binding, CI refusal, CLI and redacted transport. | +| Permanent performance suite | Independently ran six tests normally and under `python3 -O`: both pass. Covers 20-sample metadata, report preservation, dirty/unknown provenance, empty/partial samples and pipeline failure. | +| Permanent ARM suite | Independently ran nine tests normally and under `python3 -O`: both pass. Fixture stubs check exact command, six predicates, private target, no color, source hashes and cleanup; both observed classes pass and failure controls fail. These are offline contract tests, not nine real compiler runs. | +| Independent administrative attacks | `/tmp/tyrne-security-r2.F3SbJj/security-attacks.py`: 32 attacks passed. Twenty-four malformed response combinations across rulesets/GraphQL/REST/check evidence, four floating-point actor counts, three malicious/malformed SHAs and final-read GraphQL drift all refused with zero fake writes.

Fixture source hashes and cleanup checked. These experiments were run normally; no optimized-mode claim is made for the custom assert-based attack script. | +| Old-assertion negative control | In a fixture-owned temporary copy only, substituted the base 69ac script and supplied valid 101/unwind output: old assertion rejected it. Corrected exact-tip assertion accepts that same fixture. This demonstrates the test distinguishes the regression. | +| Historical actual failure | Parent supplied `/tmp/tyrne-b21-step7/registration-tip-failure.log`, hosted run 38186028266 at 69ac: intended mutation failed with the unwind class while the old E0152-only assertion failed. Historical green E0152 runs/R1 remain preserved; they did not prove absence of the race. | +| Corrected actual hosted ARM | Independently inspected parent-downloaded `/tmp/tyrne-b21-step8/fixed-hosted-arm.log`: native `aarch64-unknown-linux-gnu`; exact private probe passes with exit101 and `error: unwinding panics are not supported without std`.

All eight axes and all 33 dispositions are present. S13 preserves the existing excluded HIGH explicitly; it is not a minor newly waived finding and does not expand this review into a whole-kernel approval. + +R1's scoped T-035 security Approve remains a historical and valid scoped judgment. R1 code's inherited Medium T-036 race remains in history with its observed failing run. The 7deb correction resolves the examined assertion defect: exact compiler command and exact isolated mutation remain, accepted status is narrowed to 101, diagnostics are full-line and limited to two actually observed rejection classes, and the previously failing class now passes on a real hosted ARM run. This is not acceptance of any compiler error and not a change to production cfg gates. The paired R2 code review owns its independent final code verdict. + +Canonical publication/index/trailer work is intentionally delegated to the parent under the no-repository-edits instruction. This complete temporary artifact supplies that work; it does not claim those later writes have happened. Required final maintainer review and future default-branch dispatch/first-main evidence remain pending, with no Done promotion or merge represented here. + +## Verdict + +**Approve — the whole combined security-review scope `69ac515393f8f20ff0a11587a309182388bcde51..7deb16eae6274d48391c6c6525515a4e8bbdd66f` is ready for the next authorized review/integration step.** + +No new security blocker remains in T-035 or the included late T-036 assertion correction. The exact two-class/exit101 fix and actual corrected hosted rejection close the examined inherited diagnostic-race hold from this security perspective. Approval relies on the documented trusted-local-administrator model, additive-only supported policy and explicitly non-atomic coordinated administration; it is not assurance against concurrent or malicious administrators.

Capability correctness + +| Checklist item | Outcome, adversarial question and justification | +|---|---| +| Privileged operations require capabilities | **OK.** Could ARM host selection invoke an unintended privileged operation? Hosted targets now exclude both Tyrne SVC wrappers; bare-metal operations remain unchanged. | +| Narrowest sufficient capability | **OK.** Could the narrowing broaden console authority? No capability type, handle, right or grant changes; `console_write` retains the existing `DebugConsole`/`CONSOLE_WRITE` check. | +| Checks before side effects; no failed-check leak | **OK.** Could a failed capability check emit bytes? The unchanged dispatcher validates the capability before range checks, copying or emission (`kernel/src/syscall/dispatch.rs:236`). | +| Move-only capability transfer | **N/A.** Could this introduce accidental capability copying? No transfer or capability representation changes. | +| Explicit duplication authority | **N/A.** Could this duplicate authority implicitly? No duplication operation is introduced or modified. | +| Atomic revocation | **N/A.** Could target selection race with revocation? Selection occurs at compilation; no revocation or concurrency path changes. | + +`task_exit` continues to act solely on the calling task's identity under [ADR-0031](../../../decisions/0031-initial-syscall-set.md); this change adds no authority over another task. + +## 2. Trust boundaries + +| Checklist item | Outcome, adversarial question and justification | +|---|---| +| Inputs validated before kernel use | **OK.** Could arbitrary target strings select the Tyrne link path? Both target fields require exact equality; malformed, absent and non-Unicode values fail closed in the independent matrix. Runtime syscall argument handling is unchanged. | +| User pointers restricted to validated mappings | **OK.** Could narrowing expose a pointer to a new kernel consumer? No pointer construction or consumer changes; the existing console path retains whole-range and per-page USER checks before emission. | +| Buffer lengths range-checked | **OK.** Could a different target interpretation widen the supplied range? The slice pointer/length operands and kernel validation remain identical. | +| Typed message parsing | **N/A.** Could malformed messages exploit a new decoder? No message format or parser changes. | +| IPC cannot grant excess authority | **N/A.** Could cross-task communication bypass an authority check? No IPC or transfer code changes. | + +The compiler predicate and linker predicate agree: `aarch64 && none`. The normal ARM host uses an ordinary hello `main`; it does not select `_start`, the custom panic handler, `hello.ld`, or the SVC bodies. + +## 3. Memory safety + +| Checklist item | Outcome, adversarial question and justification | +|---|---| +| Unsafe policy compliance | **OK for narrowing; recording pending.** Could an unsafe site become reachable on an additional target? The selected target set strictly shrinks. Existing comments and audit references remain; the amendment records locations, invariants and alternatives. No new unsafe identifier is warranted. | +| Safety invariants hold for every caller | **Flagged — existing T-038, outside this approval.** Could a valid caller rely on a live value in `x2` surviving the trap? Yes: the existing input-only declaration conflicts with kernel write-back. This review expressly withholds approval of that invariant. No new `unsafe fn` or `# Safety` contract is introduced. | +| No uninitialized memory exposed | **OK for delta.** Could host compilation read uninitialized asm outputs? Hosted expansion contains no SVC sites; bare-metal output declarations and bodies are unchanged. | +| No use-after-free; raw-pointer lifetimes | **OK for delta.** Could the new branch retain a buffer pointer? Host stubs do not access or retain arguments; bare-metal borrowing and pointer lifetimes are unchanged. | +| No aliasing violations | **OK for delta.** Could the host branch create a new conflicting reference? No new references, raw-pointer operations or mutations are introduced. This does not clear T-038's separate assembly-contract defect. | + +**Explicit unsafe verdict:** Reviewed the target guards enclosing `userland/tyrne-user/src/lib.rs:101–114` and `:140–147`; I approve the compilation-boundary reasoning that restricts these existing unsafe operations to `all(target_arch = "aarch64", target_os = "none")`. I do **not** affirm the existing `console_write` SAFETY comment's complete register-discipline claim. Original unsafe bodies and operands are preserved. + +## 4. Kernel-mode discipline + +| Checklist item | Outcome, adversarial question and justification | +|---|---| +| No ISR allocation | **N/A.** Could an interrupt newly allocate? No interrupt code or allocation is changed. | +| Bounded kernel loops | **N/A.** Could malformed target values cause a runtime kernel loop? Build-time comparisons introduce no kernel execution path. | +| Minimal critical sections | **N/A.** Could the change extend a lock or IRQ-masked region? No synchronization or critical section changes. | +| No new hot-path kernel panic | **OK.** Could a host stub panic affect the Tyrne kernel? Stubs exist only outside the bare-metal configuration; explicit host calls would panic locally. Existing build-script `expect` remains build-time only. | +| Typed allocation-exhaustion errors | **N/A.** Could resource exhaustion now panic in the kernel? No kernel allocation or error path changes. | + +## 5. Cryptography + +| Checklist item | Outcome, adversarial question and justification | +|---|---| +| Reviewed primitives | **N/A.** Could a new primitive be weak? No cryptography introduced. | +| Keys absent from diagnostics | **N/A.** Could new key handling expose material? No key material or handling introduced. | +| Constant-time comparisons | **N/A.** Could target comparisons expose a secret? Architecture and OS names are public build metadata. | +| Acceptable randomness | **N/A.** Could predictable randomness weaken authority? No random source or use changes. | +| Nonce/IV/salt correctness | **N/A.** Could reuse break a cryptographic contract? No nonce, IV or salt operations. | + +## 6. Secrets and logging + +| Checklist item | Outcome, adversarial question and justification | +|---|---| +| No secrets in logs, panic output, debug prints or errors | **OK.** Could hostile target text inject diagnostic/linker directives? Target values are compared, never printed; the negative newline-injection case emitted only the two fixed rerun directives. No new runtime diagnostics expose arguments. | +| Sensitive Debug implementations redact | **N/A.** Could newly derived formatting disclose a capability? No type or `Debug` implementation changes; the existing syscall status type is unchanged. | + +`CARGO_MANIFEST_DIR` supplies the pre-existing linker path. This change does not create or claim protection against a compromised build environment. + +## 7. Dependencies + +| Checklist item | Outcome, adversarial question and justification | +|---|---| +| New dependencies follow add-dependency | **N/A.** Could this import unreviewed code? No manifest, lockfile or dependency addition. | +| Trust category understood | **N/A.** Could build-time code move into the kernel? No dependency role or linkage changes; existing in-tree userspace dependency remains. | +| cargo-vet decisions updated | **N/A.** Could an unaudited dependency slip through? No dependency graph or trust decision changes. | + +## 8. Threat-model impact + +| Checklist item | Outcome, adversarial question and justification | +|---|---| +| Reconciled with security model | **OK.** Could the target predicate become an authorization boundary? It selects the intended compilation ABI and reduces accidental hosted execution. Runtime authority remains enforced by unchanged kernel capability and mapping checks. | +| Model changes documented or tracked | **N/A — no model shift.** Does this defend against a hostile compiler or forged custom target? No such protection is claimed. Build configuration remains trusted; a custom `aarch64`/`none` target still selects the bare-metal branch. No security-model amendment is needed. | + +## Findings and recording follow-up + +**No new security findings requiring a source fix.** + +**Existing HIGH issue retained outside this approval:** `userland/tyrne-user/src/lib.rs:107` declares `x2` input-only, while `bsp-qemu-virt/src/syscall.rs:224` overwrites the saved register on return. [T-038](../../tasks/phase-b2/T-038-console-write-x2-clobber.md) explicitly tracks this. Both the operand and surrounding SVC bodies are unchanged by T-037. Passing host Miri and matching bare-metal bytes do not establish assembly soundness. + +**Minor pending audit bookkeeping at reviewed commit `f2d577f`:** `docs/audits/unsafe-log.md:770` has the provisional introducing-commit reference, and `:775` records review pending.

No CI job invokes it: the job list in `.github/workflows/ci.yml` (lines 65-277) never mentions it, `docs/guides/ci.md:55` still defers the automation to "a T-009 follow-up", and `docs/standards/infrastructure.md:82` lists it under "Planned gates" as maintainer-launched. Phase B's own flag K3-7 (`docs/roadmap/phases/phase-b.md:291`) asked for exactly this wiring once CI existed. Milestone C1's `-smp 4` smoke criterion builds on this job, so it must be a real, exercised gate before any SMP-touching PR. This task covers two HIGH items of `phase-b2.md` Track B.2-1 (line numbers as of the opening snapshot; locate by headline): "`tools/smoke.sh` ... is never invoked by CI" (line 33) and its cross-cut restatement "QEMU smoke tests ... are not wired into CI, right as Phase C begins" (line 39). It **replaces the stale T-009 cross-reference** in `ci.md:55`: T-009 was the timer-init task, and this task is the smoke-in-CI follow-up that sentence meant. ## Acceptance criteria -- [ ] `.github/workflows/ci.yml` has a `qemu-smoke` job on `ubuntu-latest` with an explicit display `name:`, a `timeout-minutes` bound, SHA-pinned actions (per `infrastructure.md` "GitHub Actions pinning"), and the `kernel-build` job's toolchain setup (pinned nightly, `aarch64-unknown-none`, `llvm-tools-preview`) plus `sudo apt-get install -y qemu-system-arm`; its steps are `tools/build-userland.sh`, `cargo kernel-build`, `tools/smoke.sh --int`. -- [ ] The plain-vs-`--int` choice is recorded in the review history: `--int` is used (see Design notes). -- [ ] On failure the job uploads the smoke trace (`${TMPDIR:-/tmp}/tyrne-smoke.$$.log`, a PID-suffixed name per `smoke.sh:65`) as an artifact. -- [ ] Negative test, recorded in the review history: on a scratch branch (never merged), a change that stops the kernel reaching `all tasks complete` (or inserts a panic) turns the job red and the trace artifact is downloadable. -- [ ] Manual step (GitHub settings, not representable in the repo): the maintainer adds the job's exact display name to branch protection's required status checks after its first run, and records the date in the review history. -- [ ] Documentation: `docs/guides/ci.md` (job table, local-command table, the `ci.md:55` paragraph rewritten to say the smoke job exists and no longer cites T-009, and the required-check list at line 90 with its "four real gates" count) and `docs/standards/infrastructure.md` (the bullet at line 82 moved from "Planned gates" to "Required gates", the "Runners" smoke line at 109, the required-checks list at 186, the job list at 209) name the new job and check name; the `ci.yml` header comment (lines 7-9) lists it among the merge gates. -- [ ] The first green run's wall time and the CI QEMU version are recorded in the review history next to the local baseline (2026-10-11, maintainer's Mac, QEMU 11.1.1: `tools/smoke.sh --int` PASS, boot-to-end 4.7 ms). +- [x] `.github/workflows/ci.yml` has a `qemu-smoke` job on `ubuntu-latest` with an explicit display `name:`, a `timeout-minutes` bound, SHA-pinned actions (per `infrastructure.md` "GitHub Actions pinning"), and the `kernel-build` job's toolchain setup (pinned nightly, `aarch64-unknown-none`, `llvm-tools-preview`) plus `sudo apt-get install -y qemu-system-arm`; it builds the debug userland/kernel and runs `tools/smoke.sh --int`, then builds the release userland/kernel and runs `tools/smoke.sh --release --int`. Build the matching userland before each profile because `hello.bin` is shared. +- [x] The plain-vs-`--int` choice is recorded in the review history: `--int` is used (see Design notes). +- [x] The debug smoke requires all three existing serial markers: `hello from userspace`, `tyrne: userspace task exited`, and `tyrne: all tasks complete`, as well as absence of panic/CPU-fault patterns. Completion alone is insufficient: kernel task A can print it without an EL0 task ever running. +- [x] Release smoke requires `tyrne: userspace task exited` and `tyrne: all tasks complete`, forbids `hello from userspace`, and rejects panic/CPU-fault patterns. Explicit ELF invocations select the correct expectation through `--release` where applicable; document and test that contract. No syscall/userland behaviour is changed for this check. +- [x] On failure the job uploads the smoke trace (`${TMPDIR:-/tmp}/tyrne-smoke.$$.log`, a PID-suffixed name per `smoke.sh:65`) as an artifact. +- [x] Negative tests, recorded in the review history: isolated copies/runner workspaces demonstrate that omitting the EL0 task, omitting completion, emitting a panic/CPU-fault trace, and injecting a greeting into a release trace each make the same smoke gate exit non-zero. The hosted probe asserts those failures and uploads a downloadable trace artifact. No scratch branch or deliberately broken commit is used; distinguish expected probe failures from the clean production job's verdict. +- [x] Production log pipelines preserve smoke rejection through explicit Bash/pipefail, with the inherited-shell negative guard passing locally and hosted. +- [x] Live GitHub step: add the job's exact display name to branch protection's required checks after its first remote green run; preserve all existing settings and record the date and read-back evidence. T-035 subsequently versions and verifies this policy; ADR-0040 specifies the approved apply arrangement. +- [x] Documentation: `docs/guides/ci.md` (job table, local-command table, the `ci.md:55` paragraph rewritten to say the smoke job exists and no longer cites T-009, and the required-check list, whose opening snapshot at line 90 counted four gates and whose current policy lists six checks) and `docs/standards/infrastructure.md` (the bullet at line 82 moved from "Planned gates" to "Required gates", the "Runners" smoke line at 109, the required-checks list at 186, the job list at 209) name the new job and check name; the `ci.yml` header comment (lines 7-9) lists it among the merge gates, and its permissions comment no longer claims that the pipeline never uploads artifacts. +- [x] The first green run's wall time and the CI QEMU version are recorded in the review history next to the local baseline (2026-10-11, maintainer's Mac, QEMU 11.1.1: `tools/smoke.sh --int` PASS, boot-to-end 4.7 ms). ## Out of scope - Multi-core runs (`--smp` above 1): the job runs the default single-core configuration; the flag itself is [T-033](T-033-qemu-tooling-smp-and-timeout.md). -- Smoke-testing the release ELF (`tools/smoke.sh --release`); [T-030](T-030-ci-release-profile-gate.md) lists it as a planned gate. - Asserting the exact EL0 SVC count or adding per-attack markers in the script: [T-067](T-067-adversarial-el0-smoke-image.md) and [T-066](T-066-bsp-syscall-context-extraction.md). - Scheduling `tools/perf-harness.sh`: [T-035](T-035-ci-hygiene-tail.md). ## Approach -Add one job, copying the `kernel-build` setup block (`ci.yml:107-134`) so the toolchain and cache keys stay consistent, then install QEMU from apt (`run-qemu.sh:74` already names the package). Run the three commands in order. `smoke.sh` without an ELF argument rebuilds the userland image and the kernel itself (`smoke.sh:50-57`); keeping the explicit `build-userland.sh` and `cargo kernel-build` steps makes a build failure distinguishable from a boot failure and the second build is incremental (alternatively pass the debug ELF path explicitly to skip it). Upload the trace with an `if: failure()` artifact step; the log name is PID-suffixed, so use a glob and, if useful, set `TMPDIR` to `${{ runner.temp }}` for the step. Top-level `permissions: contents: read` already suffices for artifact upload. Pin any new action by full commit SHA with a trailing version comment; do not copy a SHA from memory. +Add one job, copying the `kernel-build` setup block (`ci.yml:107-134`) so the toolchain and cache keys stay consistent, then install QEMU from apt (`run-qemu.sh:74` already names the package). Build and smoke debug first, then release; always produce the matching userland before the BSP. `smoke.sh` without an ELF argument rebuilds both (`smoke.sh:50-57`); explicit matching build steps distinguish compilation from boot failures, with the second build incremental (or pass the ELF path and profile explicitly). Make the marker expectations profile-aware: hello already ignores a rejected console call (`userland/hello/src/main.rs:45-47`) and exits even in release, so profile-aware marker checks need no syscall/userland behavior change. Upload traces on success and failure with an `if: always()` artifact step; PID-suffixed names require a glob, optionally with `TMPDIR` set to `${{ runner.temp }}`.

It does not count SVCs: the "exactly two EL0 `SVC` exceptions" expectation in `docs/guides/first-userspace.md` is a human-read trace property, not a scripted assertion. +- **Why `--int`.** `smoke.sh` always applies the panic/fault grep (`tyrne panic|Translation fault|Permission fault|Data Abort|Prefetch Abort|Undefined Instruction`; locate the panic/fault grep in the current script), but without `-d int,unimp` QEMU never logs exceptions, so those patterns could not match; `--int` is what makes the CPU-fault gate real. It does not count SVCs: the "exactly two EL0 `SVC` exceptions" expectation in `docs/guides/first-userspace.md` is a human-read trace property, not a scripted assertion. +- **EL0 evidence.** The completion marker is emitted independently in `task_a` (`bsp-qemu-virt/src/main.rs`, locate `all tasks complete`). Require the already-existing userspace greeting and syscall-exit marker too. This closes the boot/EL0 claim made by this task; new adversarial images and exact SVC counting remain T-067's scope. +- **Release evidence.** Require task exit/completion and forbid the greeting, matching the existing release debug-console contract. T-065 later changes that mechanism to an explicit feature and must update these smoke expectations alongside the build commands; T-067 adds console-dependent adversarial coverage separately. - The CI QEMU is whatever `ubuntu-latest` packages, likely older than the 11.1.1 used locally; the trace format the script greps is expected to be stable but the first run is the evidence. Record both versions. - GitHub's branch-protection UI offers a check only after it has run, hence the manual step follows the first run. The job's `name:` is the string to register, not its id. - **Location re-verification (2026-10-11, HEAD `400dec0`):** `ci.md:55`, `infrastructure.md:82`, `phase-b.md:291`, `ci.yml:65-277` and `smoke.sh:50-57,65,102-119` were re-checked and match; nothing drifted. `ci.md:90` and `infrastructure.md:109,186,209` are additional edit points found while verifying. `phase-b2.md` line numbers shift as banners are added, so locate its items by headline. -- Sequencing: depends on [T-033](T-033-qemu-tooling-smp-and-timeout.md) so the job is written against the final `smoke.sh` flags; it must land before any SMP-touching PR. +- Sequencing: depends on [T-030](T-030-ci-release-profile-gate.md) for release build aliases/security gates and [T-033](T-033-qemu-tooling-smp-and-timeout.md) for the final flags; it must land before any SMP-touching PR. ## Review history | Date | Reviewer | Note | |------|----------|------| | 2026-10-11 | Claude (AI agent) | opened under ADR-0040; status Ready | +| 2026-10-11 | Codex (AI agent) | Preflight contract review: see [review artifact](../../reviews/code-reviews/2026-10-11-phase-b2-track1-preflight.md); documentation corrected, implementation not started; ADR-0040 remains Proposed. | +| 2026-10-12 | Codex (AI agent) | Started approved step 6 after T-032 implementation gates and both fresh code/security rounds (`07449f1`).

The actual negative harness passes 20 synthetic trace cases plus three real private kernel variants, each exit 1 with intended diagnostic and verified marker shape/no unrelated fault. Fault cases are synthetic, not actual CPU-fault injection. All private copies/targets/images use disposable paths. Local QEMU version and logs/results: `/tmp/tyrne-b21-step6/`; the opening 4.7 ms figure is historical emulated boot timing, not this job’s wall time.

The Accepted Track B.2-1 policy chooses implementation of both items; recording those choices alone does not satisfy the remaining implementation and evidence criteria. At the opening baseline, `tools/perf-harness.sh` was the canonical source for boot-to-end timing claims but no CI job ran it (`docs/standards/infrastructure.md:114` says "Maintainer-launched only; not yet wired into CI"), so there was no automated performance signal. Separately, "what gates merge" was stated only in the `ci.yml` header comment (`.github/workflows/ci.yml:7-9`) and prose (`docs/guides/ci.md:85-91`, `infrastructure.md:186`); the actual required-checks list was a GitHub setting that no diff could review. This task covers two items of `phase-b2.md` Track B.2-1 (line numbers as of the opening snapshot; locate by headline): LOW "`tools/perf-harness.sh` is likewise never invoked by CI" (line 51) and INFO "'What gates merge' is documented only in comments, not verifiable as code" (line 60). The track's acceptance criteria explicitly allow these low/info tails to be tracked without all landing in B.2, and the phase's closing note requires a scheduled-versus-gated CI choice to be routed through ADR governance rather than decided inside the backlog. ## Acceptance criteria -- [ ] Decision D1 (perf-harness in CI) is recorded before any implementation, in the venue chosen under D3, and linked from the review history; if the answer is "not now", it is recorded under "Planned gates" in `docs/standards/infrastructure.md` instead. -- [ ] Decision D2 (merge gates as code) is recorded the same way before any implementation. -- [ ] If D1 chose a scheduled run: a workflow with `schedule` and `workflow_dispatch` triggers builds the kernel, runs `tools/perf-harness.sh --iterations=20 --report=ci-nightly`, and uploads the output as an artifact; one manual `workflow_dispatch` run is green and its artifact contents are recorded; the job is not added to the required checks. -- [ ] If D2 chose to implement: the chosen artefact (committed ruleset definition or Terraform) is in the repo with documented export, diff and apply commands, and a diff of the live settings against it is recorded as clean; otherwise "not now" is recorded. -- [ ] Documentation: `docs/guides/ci.md` and `docs/standards/infrastructure.md` (including the line-114 sentence in the performance-harness section and the "Planned gates" list) match the decisions taken; the `ci.yml` header comment (lines 7-9) is still accurate. +- [x] Decision D1 is Accepted in ADR-0040 before implementation: weekly Monday `03:17 UTC` plus `workflow_dispatch`, informational, with a `development` push trigger limited to changes to the performance workflow or harness for pre-merge validation. +- [x] Decision D2 is Accepted in ADR-0040 before implementation: version the existing classic `main` branch protection as JSON, with read-only export/check and explicit local apply tooling; no Terraform or ruleset migration. +- [x] The performance workflow builds the debug userland and kernel, runs `tools/perf-harness.sh --iterations=20 --report=ci-nightly`, and uploads the report with SHA/toolchain/QEMU metadata.

Then implement only what was chosen. For a scheduled harness run, a separate workflow file is the simplest way to keep `schedule:` off the PR pipeline (`ci.yml` triggers on push and pull_request, lines 29-33); it must follow the repo conventions (SHA-pinned actions, least-privilege `permissions`), build the userland image and the kernel first, and archive the harness report. For merge gates as code, `gh api repos/{owner}/{repo}/rulesets` (named in the plan item) is the starting point for exporting what is configured today. +Implement ADR-0040's Accepted D1-D3 policy. Use a separate performance workflow to keep measurements off the required PR pipeline; follow the repo's SHA pinning and least-privilege conventions, build the userland image before the kernel, and archive the report. Read-only inspection on 2026-10-11 found `gh api repos/HodeTech/Tyrne/rulesets` empty and `main` protected by classic branch protection. Export that existing mechanism through `gh api repos/HodeTech/Tyrne/branches/main/protection`; normalise response-only metadata separately from the apply payload, preserve all policy fields, and fail closed on settings the tooling cannot represent. Test drift detection and apply preconditions against local fixtures before any live mutation. Also query GraphQL-only deployment/review/actor policy and refuse nonempty unsupported extensions or new rulesets. Apply only after new required checks have succeeded remotely, then compare full read-back. Smoke/ARM were already registered in T-034/T-036, so this step's real apply is a verified no-op; offline fixtures exercise the mutating path. ## Definition of done Beyond the acceptance criteria: -- [ ] `cargo fmt --all -- --check` clean. -- [ ] `cargo host-clippy` clean with `-D warnings`. -- [ ] `cargo kernel-clippy` clean. -- [ ] `cargo host-test` passes. -- [ ] Every touched markdown file has all `](...)` link targets resolving. -- [ ] Commit message follows [`commit-style.md`](../../../standards/commit-style.md) with `Refs: ADR-0040` (plus the new ADR number if D3 produced one). -- [ ] Task status updated to `In Review`; [`current.md`](../../../roadmap/current.md) updated. +- [x] `cargo fmt --all -- --check` clean. +- [x] `cargo host-clippy` clean with `-D warnings`. +- [x] `cargo kernel-clippy` clean. +- [x] `cargo host-test` passes. +- [x] Every touched markdown file has all `](...)` link targets resolving. +- [x] Commit message follows [`commit-style.md`](../../../standards/commit-style.md) with `Refs: ADR-0040`. +- [x] Task status updated to `In Review`; [`current.md`](../../../roadmap/current.md) updated. ## Design notes -- **Open decisions (maintainer):** - - **D1 — perf-harness in CI.** (a) Scheduled and informational: cron plus `workflow_dispatch`, report archived as an artifact, as the plan item suggests; (b) PR-gated; (c) not now, recorded as a planned gate. Facts bearing on it: the harness has no regression threshold (`infrastructure.md:134`), and QEMU TCG shows about 15-30 % run-to-run variance (`infrastructure.md:131`), so a PR gate would be noisy and could assert nothing; a scheduled job only accumulates data until a `--baseline` mode exists. The harness exits 0 on success, 1 on environmental failure, 2 on argument errors (`perf-harness.sh:38-39`) and refuses to overwrite an existing report. - - **D2 — merge gates as code.** (a) Not now: keep the UI setting and the documented list; (b) check in a repository-ruleset definition exported with `gh api` and document how to diff and apply it by hand (applying needs an admin credential, and `infrastructure.md:104` says secrets never enter CI, so this stays a manual step); (c) Terraform (`github_branch_protection` / `github_repository_ruleset`), which adds a tool, state and a credential the repo does not have today. - - **D3 — recording venue.** A new ADR, a revision-note rider on ADR-0040, or a standards change via the [`propose-standard-change`](../../../../.agents/skills/propose-standard-change/SKILL.md) skill (the latter fits an `infrastructure.md` rule). The decision follows [`write-adr`](../../../../.agents/skills/write-adr/SKILL.md) rules if an ADR is chosen. +- **Decisions Accepted by the maintainer in ADR-0040 on 2026-10-11:** + - **D1 — scheduled informational reporting.** The harness has no regression threshold (`infrastructure.md:134`), and QEMU TCG has substantial run-to-run variance. A real performance-regression merge gate therefore needs a separate calibrated-baseline decision. This task implements measurements now rather than leaving an unspecified PR-gating option or a "not now" outcome. The harness exits 0 on success, 1 on environmental failure, 2 on argument errors and refuses to overwrite a report. + - **D2 — classic branch-protection JSON.** Preserve the live mechanism instead of migrating it merely to gain a reviewable artifact. The plan's ruleset/Terraform examples are alternatives, not evidence that a ruleset already exists. Administrative application stays local and explicit; CI receives no privileged token. + - **D3 — record the choices before Acceptance.** ADR-0040 carried these choices while Proposed; the maintainer has now Accepted them. Substantive `infrastructure.md` changes follow the Accepted ADR through [`propose-standard-change`](../../../../.agents/skills/propose-standard-change/SKILL.md); a standard edit cannot replace ADR governance. - **Location re-verification (2026-10-11, HEAD `400dec0`):** `ci.yml:7-9`, `ci.md:85-91`, `infrastructure.md:114,134,131,186,104` and `perf-harness.sh` exit codes were re-checked and match; nothing drifted. `phase-b2.md` line numbers shift as banners are added, so locate its items by headline. -- Sequencing: after [T-034](T-034-ci-qemu-smoke-job.md); the plan item defers the schedule until the smoke job lands. +- Sequencing: after [T-034](T-034-ci-qemu-smoke-job.md) and [T-036](T-036-ci-arm64-host-check-job.md), so the committed protection definition includes both remote-green checks. The plan item defers the schedule until the smoke job lands. +- **Schedule semantics:** [GitHub's event reference](https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows#schedule) documents possible delays/dropped scheduled runs and public-repository inactivity disabling; weekly reporting is recurring evidence, not an execution-time guarantee. ## Review history | Date | Reviewer | Note | |------|----------|------| | 2026-10-11 | Claude (AI agent) | opened under ADR-0040; status Draft | +| 2026-10-11 | Codex (AI agent) | Preflight contract review: see [review artifact](../../reviews/code-reviews/2026-10-11-phase-b2-track1-preflight.md); documentation corrected, implementation not started; ADR-0040 remains Proposed. | +| 2026-10-11 | @cemililik; Codex recorded the decision | ADR-0040 Accepted after the [approval follow-up](../../reviews/code-reviews/2026-10-11-adr-0040-approval-follow-up.md); design choices settled, status Ready.

The decision drivers that dominate are *security-first on the EL0 boundary*, *one unambiguous status*, and *concurrency amplifies debt*. Option A is the only option that both closes every verification gap before concurrency work starts and leaves no half-gated ambiguity. The costs (delay, and gating on many low-severity items) are real and are addressed by the exit-bar definition and the checkpoint below rather than by narrowing the scope up front. The concrete rules: 1. **Structure and identifiers.** Phase B.2 sits between Phase B and Phase C. The dotted identifier `B.2` is a deliberate, narrow extension of ADR-0013's letters-only phase IDs: it avoids renumbering Phases C–J, which ADR-0013 declares stable. Its sub-units are **Tracks** `B.2-1`…`B.2-6` (not milestones, which would collide with `B0`–`B6`). Its phase file is `phase-b2.md`, and its task folder is [`docs/analysis/tasks/phase-b2/`](../analysis/tasks/phase-b2/). Any future bridge phase follows the same pattern. -2. **Gate.** Phase B.2 is a **hard prerequisite** of Phase C and Phase D (the `B2 --> C` and `B2 --> D` edges of the dependency graph are binding). While B.2 is open, no Phase C or Phase D milestone may open and no Phase C or Phase D implementation task may leave `Draft`. Planning artefacts for Phase C — scoping drafts, `Proposed` ADRs, the readiness sweep ([T-074](../analysis/tasks/phase-b2/T-074-phase-c-readiness-sweep.md)) — are allowed and encouraged so that Phase C starts without delay once B.2 closes. The two SMP-critical defects (`StaticCell`'s blanket `Sync`, the non-atomic PMM bitmap) remain Phase C entry gates and are *not* fixed in B.2; B.2 only corrects the false safety premise comment in `pmm.rs` ([T-042](../analysis/tasks/phase-b2/T-042-pmm-defensive-validation.md)). -3. **Scope and exit bar.** The exit bar is the acceptance criteria of Tracks B.2-1 to B.2-6 as written in `phase-b2.md`, including each track's own deferral clauses (low/info tails that are "tracked even if not all land"). Of the 141 plan items, 140 are owned by tasks T-030…T-073 (one of them, the `current.md` / T-029 staleness item, is split between T-047 and T-048) and one — the `phases/README.md` living-document note — was already fixed by the kickoff; the 71 polish items are **not** gating as a set and stay in `phase-b2.md` as an opportunistic backlog (a few are consumed by named tasks, as the task index records; those tasks are gating only for their plan items). Two tasks are polish and optional for exit — [T-036](../analysis/tasks/phase-b2/T-036-ci-arm64-host-check-job.md) and [T-056](../analysis/tasks/phase-b2/T-056-docs-consistency-automation.md) — and, if not completed, are recorded as carry-forwards in the closure review. A task that ends in an explicit "decide and record" outcome (for example T-035, T-039, T-065) satisfies exit by recording the decision, not necessarily by implementing it. -4. **Status of Phase C.** Phase C is reclassified from "active" to "**next, gated by Phase B.2**". The statements this ADR supersedes are: `phase-b.md` §Phase B closure ("Phase C is now active"), `docs/roadmap/current.md` (the *Active phase* bullet naming Phase C), the status paragraphs of `README.md` and `CLAUDE.md`, and the "Recommended before Phase C" wording in `phases/README.md`. They are updated in the same change. When B.2 closes, Phase C becomes active again and these statements are restored by the closure task ([T-075](../analysis/tasks/phase-b2/T-075-phase-b2-closure.md)). +2. **Gate.** Phase B.2 is a **hard prerequisite** of Phase C and Phase D (the `B2 --> C` and `B2 --> D` edges of the dependency graph are binding). Phase D ports the same aarch64 kernel/HAL, MMU and syscall foundations to Pi 4; it directly needs the corrected contracts and verification gates rather than copying known defects into a second BSP. This deliberately applies the same whole-phase exit bar to D even if C and D overlap after B.2; it does not depend on C finishing first. While B.2 is open, no Phase C or Phase D milestone may open and no Phase C or Phase D implementation task may leave `Draft`. Planning artefacts for Phase C — scoping drafts, `Proposed` ADRs, the readiness sweep ([T-074](../analysis/tasks/phase-b2/T-074-phase-c-readiness-sweep.md)) — are allowed and encouraged so that Phase C starts without delay once B.2 closes.

A task whose acceptance criteria permit an explicit, evidenced "decide and defer" outcome can satisfy phase-exit accounting that way. Choosing implementation requires the task's remaining implementation and verification criteria; recording a "yes" decision alone does not complete it. Neither exit accounting nor an agent review authorises a `Done` promotion. +4. **Status of Phase C.** Phase C is reclassified from "active" to "**next, gated by Phase B.2**". The statements this ADR supersedes are: `phase-b.md` §Phase B closure ("Phase C is now active"), `docs/roadmap/current.md` (the *Active phase* bullet naming Phase C), the status paragraphs of `README.md` and `CLAUDE.md`, the "Recommended before Phase C" wording in `phases/README.md`, and the Phase C status targets in `phase-b2.md` Track B.2-2. Live targets are corrected and dated historical statements receive explicit supersession notes in the same change. When B.2 closes, Phase C becomes active again and the live pointers advance through the closure task ([T-075](../analysis/tasks/phase-b2/T-075-phase-b2-closure.md)); historical records remain preserved. 5. **Evidence and verification discipline.** `phase-b2.md` is self-contained: every item stands on its own `file:line` location. The source review is a local-only document and is **not** a dependency of any task. Because that review was static, **every B.2 task begins by re-verifying its item against the live tree**; an item that no longer reproduces closes with evidence and no code change. B.2 closure includes a verification report that accounts for all 141 items as *fixed*, *not reproduced*, or *deferred with a recorded reason*. 6. **Inherited process.** Tasks are opened with the [`start-task`](../../.agents/skills/start-task/SKILL.md) skill; every `unsafe` change follows [`justify-unsafe`](../../.agents/skills/justify-unsafe/SKILL.md) and the append-only audit-log discipline; changes that touch capabilities, IPC, syscalls, memory or `unsafe` get a security review per [`security-review.md`](../standards/security-review.md); a design decision surfaced by a task is routed through an ADR or a revision-note rider rather than decided silently (as `phase-b2.md`'s closing note already requires). Closure follows ADR-0013 (business review) and additionally includes a security review of B.2's `unsafe`/asm/capability changes and a regression check (host tests, Miri, `tools/smoke.sh --int`, release build). -7. **ADR numbering.** This ADR takes **0040**, the next free number after 0039, as the [`write-adr`](../../.agents/skills/write-adr/SKILL.md) skill prescribes. The phase ledgers in `phase-c.md`…`phase-i.md` assign *tentative* numbers starting at 0040 ("final numbers are assigned when the ADR is actually written"); those placeholders now shift and already collide between Phase C and Phase D. They are ordinal placeholders only, and re-sequencing them is [T-054](../analysis/tasks/phase-b2/T-054-adr-ledger-renumbering-cascade.md).

They take effect upon maintainer Acceptance of this ADR; a proposal alone authorises no implementation or live repository-setting change. + +This wave also includes release kernel clippy and both debug/release QEMU smoke in T-030/T-034. The existing hello program ignores a rejected console call and exits, so debug can require its greeting while release forbids that greeting; both must demonstrate task exit/completion without panic or CPU fault. No userland or syscall-gate mechanism change is needed to establish those runtime checks. + +1. **Performance reporting — weekly and on demand, informational.** Implement T-035 with a separate workflow scheduled weekly at `03:17 UTC` on Monday, plus `workflow_dispatch`. Also run it on pushes to `development` that change this workflow or `tools/perf-harness.sh`, so the job and its downloadable report can be verified before default-branch registration. Build the debug userland and kernel with the pinned nightly, run `tools/perf-harness.sh --iterations=20 --report=ci-nightly`, and archive the report with the commit SHA, toolchain and QEMU version. A failed measurement is a visible failed workflow; timing changes do not block merges. There is no calibrated regression threshold today, and QEMU TCG measurements vary with the runner. This wave adds recurring evidence without pretending it proves a performance-regression bound. +2. **Merge policy — version the existing classic branch protection.** On 2026-10-11, read-only inspection of `HodeTech/Tyrne` found no repository rulesets (`GET /repos/HodeTech/Tyrne/rulesets` returned `[]`); `main` instead has classic branch protection with four required GitHub Actions checks, strict up-to-date checking, required linear history and conversation resolution, and disabled force pushes and deletion. Implement T-035 with a committed JSON definition of that existing policy and documented read-only export/check commands plus an explicit maintainer-side apply command. Preserve every existing setting, including the check-source application binding; add the smoke and ARM checks only after they have succeeded remotely. Do not introduce Terraform, migrate protection mechanisms, grant a CI job administrative credentials, or remove an existing required check. An unexpected live-policy change must stop application for reconciliation rather than be overwritten silently. +3. **ARM host verification — a required PR check.** Include T-036 in this requested Track B.2-1 implementation, although it remains optional for the phase-wide exit bar. Use the explicit GitHub-hosted `ubuntu-24.04-arm` runner and pinned nightly; run workspace `cargo check`, `cargo clippy --all-targets -- -D warnings`, `cargo test` and `cargo miri test`, each excluding only `tyrne-bsp-qemu-virt`. Native tests exercise host linking; Miri also reproduces the command that originally exposed the target-gating bug. The public repository can use this standard ARM runner without a paid-runner commitment ([GitHub runner reference](https://docs.github.com/en/actions/reference/runners/github-hosted-runners)). Install T-037 first, isolate caches by runner architecture, and make the ARM job required after its first remote green run. +4. **Execution and evidence — one branch, reviewed steps.** Follow the maintainer's requested `development`-only workflow: implement and commit one step, complete two rounds with fresh independent reviewers, fix and commit confirmed findings, then continue automatically. A dependent task may start when its predecessor is implemented and its applicable gates and both review rounds pass on this branch; the predecessor remains `In Review` until the maintainer reviews and merges the final PR. This is the explicit stacked-execution exception to the usual dependency-`Done` rule, limited to this Track B.2-1 sequence and its T-037 prerequisite. No task is promoted to `Done` by an agent. Run negative experiments in isolated temporary copies and, where hosted evidence is required, in isolated runner workspaces; do not create scratch branches or commit deliberately broken source. Distinguish a failing command inside an expected-failure probe from a red workflow. Record local evidence, hosted evidence, and post-merge evidence separately; a first `main` run or default-branch-only dispatch can only be certified after the maintainer's merge. + +These choices are implemented by existing tasks; they allocate no new task or ADR identifiers. Substantive changes to the corresponding infrastructure standard follow this ADR's Acceptance, using [`propose-standard-change`](../../.agents/skills/propose-standard-change/SKILL.md).

Every exact cache key includes OS, architecture, toolchain and lockfile hash.

Executable `~/.cargo/bin` paths are excluded; registry and build caches remain inputs executed by the build, not integrity-attested code.

Cache scope does not grant a workflow additional trust or make caches suitable for secrets. ### Why do the kernel jobs run on the pinned nightly, not stable? -The kernel needs nightly to build (inline asm intrinsics / lang items — see `rust-toolchain.toml` and ADR-0002). `rust-toolchain.toml` pins `nightly-2026-01-15` at the repo root, and rustup's override precedence means that file selects the pinned nightly for **every** in-repo `cargo` invocation regardless of `rustup default`. So `lint-and-host-test`, `kernel-build`, `miri`, and `coverage` all select the pin explicitly (`cargo +$NIGHTLY_PIN …`) — the same toolchain a contributor's local `cargo` uses. +The kernel needs nightly to build (inline asm intrinsics / lang items — see `rust-toolchain.toml` and ADR-0002). `rust-toolchain.toml` pins `nightly-2026-01-15` at the repo root, and rustup's override precedence means that file selects the pinned nightly for **every** in-repo `cargo` invocation regardless of `rustup default`. So `lint-and-host-test`, `kernel-build`, `qemu-smoke`, `arm64-host-check`, `miri`, and `coverage` all select the pin explicitly (`cargo +$NIGHTLY_PIN …`) — the same toolchain a contributor's local `cargo` uses. ### What does `host-stable-check` give us, then? A genuine "the host-buildable crates compile and pass tests on **stable** Rust" signal. It runs `cargo +stable build` and `cargo +stable host-test` over the workspace `default-members` (kernel, hal, test-hal) — the bare-metal BSP is excluded because it needs nightly. The `+stable` prefix bypasses the `rust-toolchain.toml` override so this job exercises stable for real. It deliberately does **not** run clippy/fmt with `-D warnings`: `clippy::pedantic` is `warn` workspace-wide and stable is a rolling toolchain, so a future stable pedantic lint could redden the gate with no code change of ours — lint/format enforcement lives only on the pinned-nightly jobs. If a host crate ever grows a `#![feature(...)]` it does not strictly need, this job is the one that goes red on stable. +### Why an ARM64 host job? + +An arch-only `target_arch = "aarch64"` cfg accidentally includes bare-metal panic handlers and entry points on an ARM host. Cross-building on x86 cannot expose that host hazard. `arm64-host-check` verifies the machine is `aarch64` and Rust targets `aarch64-unknown-linux-gnu`, then runs the four native gates below with the pinned nightly, with Miri setup and the arch-only rejection probe. Only the BSP is excluded; both userland crates participate. Miri is mandatory alongside native compilation and execution. + +```sh +cargo check --workspace --exclude tyrne-bsp-qemu-virt +cargo clippy --workspace --exclude tyrne-bsp-qemu-virt --all-targets -- -D warnings +tools/test-ci-gates.sh --arm-host +cargo test --workspace --exclude tyrne-bsp-qemu-virt +cargo miri setup +cargo miri test --workspace --exclude tyrne-bsp-qemu-virt +``` + +The ARM-only probe first requires the exact workspace clippy command to pass on the unmodified temporary copy, with a private Cargo target. A failing clean baseline stops before mutation, including when it emits one of the recognized error classes. It then restores hello's six arch-only predicates in that same copy and requires the exact workspace clippy command to exit 101 with either the full duplicate-`panic_impl` diagnostic or `error: unwinding panics are not supported without std`. Cargo's parallel all-targets build can report the test harness or normal `no_std` binary first. The probe prints the diagnostic actually observed; tool failures, unrelated errors and unexpected success are refused. `python3 tools/test-arm-host-probe.py` permanently exercises both observed compiler failures and refusal/cleanup paths with offline fixtures. A successful probe means the compiler rejected the regression, not that Miri failed in production. It refuses non-ARM Rust hosts, uses a private Cargo target and removes the temporary copy on exit. [T-036](../analysis/tasks/phase-b2/T-036-ci-arm64-host-check-job.md) separates Apple Silicon, hosted Linux ARM, final PR and post-merge evidence.

Tags are mutable; SHAs are not. This applies the same anti-silent-drift discipline used for `NIGHTLY_PIN` and `cargo-llvm-cov` to the actions that wrap them — `taiki-e/install-action` in particular downloads and executes a prebuilt binary, so a tag repoint would be arbitrary code execution in CI.

A passing probe means the deliberate regression was rejected; it is not a red production workflow. The copy is removed on exit, with no source, branch or shared image change. ShellCheck's installed version is printed in CI; measured local and hosted versions are recorded in [T-031](../analysis/tasks/phase-b2/T-031-ci-userland-clippy-and-shellcheck.md). + +The release guard runs `cargo test --release -p tyrne-kernel --lib -- console_write_is_absent_in_release_builds console_write_number_is_bad_syscall_in_release_build` and requires both exact test names to pass plus a two-pass summary. Cargo's success alone is insufficient: setting release `debug-assertions = true` compiles both tests out, returns success with zero tests and exposes `console_write`. The `--release` probe makes that profile change only in its disposable copy and requires the guard to reject it. [T-030](../analysis/tasks/phase-b2/T-030-ci-release-profile-gate.md) records local and hosted evidence separately. + +The HAL and BSP deny `clippy::panic`, `clippy::unwrap_used` and `clippy::expect_used` at their crate roots. The `--hal` and `--bsp` probes inject a non-test `None` unwrap outside any allowed function, then require the exact `cargo host-clippy` / `cargo kernel-clippy` command to fail with `clippy::unwrap_used`. The BSP probe first builds its matching debug userland image inside the disposable copy; it never overwrites the checkout's shared image. Existing boot/demo/benchmark invariants and deliberate fatal aborts have narrow function-scoped exceptions with reasons, catalogued in [T-032](../analysis/tasks/phase-b2/T-032-panic-family-denies-hal-bsp.md). These three lints do not prohibit `assert!` or prove a panic-free kernel. + +The kernel job builds debug first, then release with its matching userland image, then restores the debug userland immediately before debug perf-bench build/lint.

Debug requires exact serial lines `hello from userspace`, `tyrne: userspace task exited` and `tyrne: all tasks complete`. Release requires exit/completion and forbids any userspace greeting. Both reject panic/CPU-fault patterns. Job-scoped explicit Bash enables pipefail so `tee` cannot turn a failed production smoke into a green step. A separate synthetic completion-only probe deliberately fails the actual smoke entry point through the inherited CI log pipeline; it requires nonzero pipeline status plus the real missing-exit diagnostic, and retains its output artifact. Removing pipefail makes this guard fail. An explicit ELF skips compilation; pass `--release` for release expectations.

It contains production PID-suffixed raw traces, combined output, probe traces/results/build logs, source/run identity, QEMU/Rust versions and diagnostic wall time.

BSP code is exercised indirectly via the QEMU smoke test; automating that runs under CI is a T-009 follow-up (the timer init task) — once the kernel can produce a finish-signal, QEMU can exit non-zero on mismatch and CI can assert the trace. +The BSP is a bare-metal `no_std` + `no_main` binary whose panic handler conflicts with `std`'s `panic_impl` lang item when built for the host target (which Miri and llvm-cov both require).

The completed demo spins, so QEMU is stopped by a watchdog; the smoke verdict comes from the trace, not the expected timeout exit status. ## When does the coverage job start gating? -Today `coverage` is informational: `continue-on-error: true` in the workflow. After T-011 closes (which raises `sched/mod.rs` past 90 % and the workspace past 96 %), the plan is to flip this job to enforce a floor.

The version is in the workflow as `tool: cargo-llvm-cov@` (`0.6.16` at the time of writing). Pinning the tool prevents an upstream release from silently changing what "coverage" reports. Current pins: -- `NIGHTLY_PIN = nightly-2026-01-15` (set 2026-04-23 when R6 landed). +- `NIGHTLY_PIN = nightly-2026-01-15` (set 2026-04-23 when R6 landed; shared by both workflows). - `cargo-llvm-cov 0.6.16` (set 2026-04-28; see `coverage` job in `ci.yml`).

Open an issue titled "Bump <pin> to <new-version>" stating the reason (new Miri check we want, a compiler feature we need, a cargo-llvm-cov bug fix, a security advisory, routine refresh). -2.

It has no PR trigger. Each run builds matching debug userland/kernel, runs `tools/perf-harness.sh --iterations=20 --report=ci-nightly` and uploads `performance--` for 14 days. New reports include full SHA, tracked-worktree state, the Rust toolchain identifier/compiler, QEMU, host OS/release/machine, all valid raw samples, failed count, wall time and the percentile band. The toolchain explanation containing the checkout path and the host name are omitted; failed optional metadata commands produce `(unknown)` without discarding measurements. Earlier baseline reports retain their original captured metadata as historical evidence. The artifact also has run/source identity, full Rust/QEMU versions and harness output; available diagnostics upload even when measurement fails. Reports refuse overwrites and are downloaded artifacts, never committed by CI. Explicit Bash/pipefail propagates harness failures through logging. + +A failed measurement/build/upload is a visible failed workflow. There is no calibrated performance threshold; neither this job nor coverage is in the required-check definition.

Suppress only demonstrated false positives with a scoped directive and a reason. +- Isolated expected-failure lint probes (`tools/test-ci-gates.sh --shell` / `--userland`) assert that the corresponding real commands reject a deliberate regression with the expected diagnostic. Their success confirms rejection, not a failure of the production gate. - `cargo test` — host-runnable unit and integration tests over `default-members` (`lint-and-host-test`; re-run on stable by `host-stable-check`). -- `cargo kernel-build` — the kernel ELF builds clean for `aarch64-unknown-none` (`kernel-build`). +- `cargo test --release` over `default-members`, plus `tools/check-release-tests.sh` requiring both named release-only `console_write` tests to pass. `tools/test-ci-gates.sh --release` must reject an isolated release `debug-assertions = true` profile flip (`lint-and-host-test`); a zero-test Cargo success is not a passing gate. +- `cargo kernel-build` and `cargo kernel-build-release` — debug and release kernel ELFs build clean for `aarch64-unknown-none`, each after its matching userland image (`kernel-build`). Release kernel clippy also denies warnings: `cargo clippy --release --target aarch64-unknown-none -p tyrne-bsp-qemu-virt -- -D warnings`. +- Debug `perf-bench` build and clippy: restore the debug image with `tools/build-userland.sh` immediately before `cargo build --target aarch64-unknown-none -p tyrne-bsp-qemu-virt --features perf-bench`, then `cargo clippy --target aarch64-unknown-none -p tyrne-bsp-qemu-virt --features perf-bench -- -D warnings` (`kernel-build`). Do not append Cargo flags to the existing lint alias after its `--` delimiter. - Host crates build and test clean on **stable** Rust (`host-stable-check`); lint/format enforcement is nightly-only (see the job note above). - Miri (Stacked Borrows) over the host-test suite (`miri`) — see §"Miri as a blocking gate" below. +- Native ARM workspace check/clippy/test/Miri on `ubuntu-24.04-arm` (`arm64-host-check`), excluding only the BSP. Verify the actual ARM machine and Rust host; run the isolated arch-only hello clippy rejection probe after positive clippy. All four commands are mandatory; see [ci.md](../guides/ci.md#why-an-arm64-host-job) for exact commands. Its live required-check registration and full-policy read-back completed on 2026-10-12 after hosted green and both fresh rounds. + +- Single-core debug/release QEMU EL0 smoke (`qemu-smoke`, display `QEMU debug + release smoke (nightly)`) after matching userland/kernel builds, with `--int`. Debug requires greeting/exit/completion; release requires exit/completion and forbids greeting. Both reject panic/CPU-fault traces; explicit Bash/pipefail preserves smoke failure through `tee`, with an inherited-shell rejection guard. Synthetic trace fixtures and three isolated real kernel mutations must demonstrate intended rejection. Always-uploaded diagnostic artifacts retain production/probe traces and metadata for 14 days. Live required-check registration was completed on 2026-10-12 after corrected remote green and both fresh rounds, recorded in [T-034](../analysis/tasks/phase-b2/T-034-ci-qemu-smoke-job.md). ### Planned gates (not yet enforced) These appear in the release/standards prose but have **no CI job yet**; do not assume a green CI exercised them. -- QEMU smoke — kernel boots under `qemu-system-aarch64 -machine virt` and reaches the success marker. *(As of 2026-05: maintainer-launched only; no `qemu-smoke` CI job yet — tracked as a B2-or-later roadmap follow-up. A behavioural gate, not a no-op — its absence means boot behaviour is verified by the maintainer, not by CI.)* - `cargo audit` — fails on known advisories; `cargo-audit` database refreshed weekly in CI. *(Currently dormant: `Cargo.lock` carries zero external dependencies, so the gate would be a no-op today. Wired in once the first external dependency lands per [add-dependency](../../.agents/skills/add-dependency/SKILL.md).)* - `cargo vet check` — fails if any dependency is not audited. *(Same dormant conditional as `cargo audit` above — zero external deps today.)* ### Advisory gates (warn, do not block) - `cargo-geiger` report — records `unsafe` counts, compared against the audit log. -- Coverage delta (via `cargo llvm-cov`) — **informational, not a gate.** The `coverage` job runs with `continue-on-error: true`, so a coverage drop never blocks a merge today; the job exists to make trends visible. The plan is to flip it to enforce a floor after T-011 settles the workspace shape — at which point `continue-on-error` is removed first and only then is the job added to branch protection (see [ci.md](../guides/ci.md) §"Branch protection"). Until then it must **not** be in the required-checks list (a `continue-on-error` job reports a neutral verdict that never satisfies `required == passing`). +- Coverage delta (via `cargo llvm-cov`) — informational and excluded from the versioned required policy. `continue-on-error: true` permits workflow success despite job failure; it does not specify a coverage floor or a particular UI conclusion. T-011 is already complete. An enforcing floor requires a separately reviewed baseline/policy and workflow change; see [ci.md](../guides/ci.md#when-does-the-coverage-job-start-gating). +- Weekly boot-to-end performance reports — Monday 03:17 UTC plus dispatch and targeted development validation, separate from PR CI. Failed measurements are visible failed workflows; no timing-regression threshold or required check is claimed. See [ci.md](../guides/ci.md#weekly-performance-reports). - Binary size delta (`cargo bloat`) — informational; large increases prompt a question. ### Miri as a blocking gate The `miri` job runs the host-test suite under Stacked Borrows on the pinned nightly and does **not** set `continue-on-error` — a Miri regression is a hard stop. It is intended as a blocking gate, with particular weight on changes under `kernel/src/sched/**` and `kernel/src/ipc/**`, where aliasing and `unsafe` invariants are densest (see ADR-0021 / UNSAFE-2026-0014). Ideally a lightweight `unsafe`-audit-log reconciliation (every `unsafe` block has a current `SAFETY:` comment, no undocumented `unsafe`) runs alongside it; that reconciliation is not yet a CI job and is performed at review time per [unsafe-policy.md](unsafe-policy.md). -**Required-status enforcement lives in GitHub branch protection (a UI setting), not in this repository.** The in-tree workflow makes the `miri` job correct and gating-by-construction; whether a green Miri is actually *required* to merge is configured in the repository settings and is outside version control. The branch-protection checklist in §"Branch protection and merge rules" below names the jobs that must be marked required. +**Required-status enforcement lives in GitHub classic branch protection.** Its complete supported definition is versioned in [main.json](../../.github/branch-protection/main.json); read-only export/check and explicit local additive-check apply use [branch-protection.py](../../tools/branch-protection.py). REST policy plus GraphQL-only deployment/review/actor flags and the no-rulesets baseline are captured. Unknown/unrepresentable policy or unexpected drift stops apply, and all app bindings/settings are preserved. CI receives no administrative credentials; offline fixtures validate safety boundaries. The [guide](../guides/ci.md#versioned-classic-branch-protection) documents commands, representability limits and the non-atomic external-administrator race. ### CI platform - GitHub Actions is the default. Workflows live under `.github/workflows/`. -- Jobs are reusable — shared setup (install toolchain, cache cargo registry) is a composite action. -- A top-level `permissions: contents: read` block applies least privilege to the auto-provisioned `GITHUB_TOKEN`: the pipeline only reads the repo and runs builds, so it gets read scope and nothing more. Any future job that genuinely needs a wider scope (e.g. publishing artifacts) declares its own `permissions:` block at the job level rather than widening the workflow default. -- CI caches `~/.cargo/registry` and `target/` keyed by the toolchain hash. +- Jobs currently repeat toolchain installation and cache setup directly in each workflow; no shared composite action exists. +- A top-level `permissions: contents: read` block applies least privilege to the auto-provisioned `GITHUB_TOKEN`: the pipeline reads the repo, runs checks and uploads diagnostic artifacts through runtime artifact credentials without widening token scope. A future job that genuinely needs wider GITHUB_TOKEN permissions must declare them at the job level rather than widen the workflow default. +- CI caches cargo data and `target/` keyed by toolchain and lockfile identity; every key and restore prefix includes `runner.os` and `runner.arch`, preventing cross-architecture restoration. - Secrets never enter CI. If a future workflow needs a secret (e.g. publishing artifacts), it is scoped and rotated. ### Runners -- `ubuntu-latest` for the standard toolchain matrix. -- `qemu-system-aarch64` on the Linux runner for smoke tests. +- `ubuntu-latest` (x86_64) for the standard toolchain matrix. +- `ubuntu-24.04-arm` for mandatory native workspace check/clippy/test/Miri, including host-gated userland and excluding only the BSP; the job verifies the native machine/Rust host and has a 15-minute bound. +- `qemu-system-aarch64` from `qemu-system-arm` on the `ubuntu-latest` smoke runner; the job records its version and has a 10-minute bound. Debug/release use one core, with no SMP claim. - Real-hardware jobs (Raspberry Pi lab, when it exists) are self-hosted runners, off the PR hot path, running on release cadence. ## Performance harness -`tools/perf-harness.sh` is the canonical source for boot-to-end timing claims. It wraps `tools/run-qemu.sh` in an iteration loop with a per-run watchdog, parses the kernel's `boot-to-end elapsed = X ns` emission out of each run's serial output, and prints `min / p10 / p50 / p90 / p99 / max / mean / stddev` in both ns and ms. Maintainer-launched only; not yet wired into CI (matches the QEMU smoke convention above — promotion to a CI gate is a B2-or-later follow-up alongside the smoke job). +`tools/perf-harness.sh` is the canonical source for boot-to-end timing claims.

It can be launched locally and by [performance.yml](../../.github/workflows/performance.yml): weekly Monday 03:17 UTC, manual dispatch and targeted development push validation, with 20 debug iterations and 14-day report artifacts.
