feat: source navigation echoes and guarded fork-prefix inheritance by AdityaVG13 · Pull Request #6393 · codewhale-hq/Codewhale

AdityaVG13 · 2026-09-21T21:35:05Z

Preserves @AdityaVG13's index-free source-navigation echoes, bounded source reads and guarded fork-prefix inheritance on the current Engine. Original contributor commits remain in the ancestry. Current head: 6f404da8eea22f68ede46a04803d008de907f6ee, integrated with main 248634f86842b3fca89ba73b067a363095e755eb.

The feature keeps the complete policy-allowed child tool vector. Header inheritance is restricted to matching first-level Chat Completions routes with the installed opaque receipt; it freezes the parent's observed header at spawn and records the actual prepared header through the protected transcript path. Changed route/model/receipt or unsupported dialects take the cold path. Deleted-symbol echoes inspect old and new spans. Source reads retain containment, deny rules and blocking-worker fences. Content scans open at most 32 candidate bodies; directory enumeration and kernel latency are not bounded by that cap. Eligible skill names remain enumerable, workflow events retain task/workspace ownership, and current eager tools plus the eight-name/16 KiB deferred cache stay intact.

All 12 original review findings were source-fixed and resolved after inspecting direct consumers. The original feature declarations and three registry rows remain; generated docs combine contributor text with main, and AdityaVG13/printf033 credits are preserved. This source disposition is separate from native qualification.

The measured runtime budget records seven numeric reductions and four cumulative context-identity changes from removing native skill paths from the ambient index. The actual hosted receipt binds to the identical 5687729921 tree: representative bytes 9803→9747 and estimated tokens 2451→2437; all other 48 numeric metrics, 17 identities and seven history notes are unchanged. No ceiling increased. These are fixture estimates, not measured provider savings. The checker exposes full mismatch diagnostics; fallback base comparisons use an isolated Cargo target to avoid replacing current-PR dependency artifacts. Existing checker/harness tests passed (48 total). Prior resulting-head Lint actually passed all 55 runtime metrics and the persistence gate; its raw current-tree results were checked, not inferred from an advisory green status.

The new integration includes main's Runtime authority/workspace fixture repair and denial of stale approval/input requests, plus macOS LLVM setup and Windows startup diagnostics. The sole overlap adds the existing fixture's owner session identity; source-navigation code and measured budgets are unchanged. The main repair passed 387 focused existing Rust tests, npm 1,312 tests (7 skipped), and check:web. These are main evidence, not resulting-PR qualification.

Fresh CI is pending. The contributor returned this PR to draft on October 15 and described further navigation work and contemporaneous measurements in their scope update. It remains draft; merging the published slice requires clarification of that intended scope as well as exact-head native, web and actual budget gates. A green check alone does not mark the contributor’s work ready. Historical Ubuntu/Windows passes at earlier heads remain recorded in commits and receipts; the immediately previous 1213 Ubuntu suite failed on the inherited main Runtime fixtures (19,076 passed, 96 failed, 2 timed out, 34 skipped). The corrected handback fixture itself passed; its two-request/no-retry/usage assertions remain unchanged. Previous failures are not relabeled as passes.

No live-provider cache savings, universal scan-latency, device or final-package acceptance is claimed. 0.10.2 has not shipped. Contributor history and source branch are preserved.

Sound every file read, grep, file search, and project map with its surroundings — sibling podmates, line-numbered symbols, import roots, resolved file links, and (in the terminal buzz) reverse-link callers — sounded fresh from source with no index, no background work, and no new dependencies. Deterministic (sorted, capped, budgeted) so repeated calls are byte-identical and cache-friendly. Echolocation (new: tools/echolocation.rs, ~2.5k lines incl. tests): - read footer: [Pod] mates + [Sounding] symbols/imports/links/heard-by, 1200B hard budget; miss echo on NotFound (denylist-gated, never fires on refused probes); terminal buzz adds callers after 2 distinct files read in a pod - grep + file_search chart matched dirs (caller's own visibility gates: denylist, excludes, extensions, gitignore); project_map sounds key files; 4 sounding languages (Rust/Python/JS-TS/Go) Token diet (no compression, behavior-preserving): - prefix 14,241 -> 7,118 tokens/turn (-50.0%): skill path cut (load_skill resolves names), MCP prose 1526->548B (scar-tissue phrases kept), agent+workflow deferral, goal tools conditional-eager keyed off the turn's resolved goal (preview/wire-safe) - activation cache: best-match-last push + regex name-rank + 16->24KiB bound (fixes deferral stranding agent behind its own discovery set) - grep empty-context omit, workflow event projection (lossless: duplicates dropped, workspaces hoisted, branch kept) + zero-memo omit - wire-prefix dump moved to PreparedOutboundRequest (exact-final-body) Evidence: targeted echo 46, workflow 131, file 145 green; full tui+workflow suites green except 4 failures reproducing identically on base c75b233 (pre-existing, unrelated) + known timing flakes proven solo-pass; clippy zero on owned files. Research: codewhale-research/ ECHOLOCATION-THESIS.md (exp-10/11/12 + hardening audit).

DEFAULT_ACTIVE_NATIVE_TOOLS is six names now (agent, workflow, get/update_goal deferred); the web contract mirror, tool docs, and mode docs still claimed ten eager + eleven with tool_search. Activation cache bound 16 -> 24 KiB in facts, docs, and web copy. Found by the fork staging PR's Lint & Type Check gate.

Footer squeeze (all lossless): same-pod links/callers render bare, import roots a link already names drop by file stem or package path, framing tightens to [Pod (N)] / [Sound], and sounded paths are /-separated on every OS. The squeeze follows CODEWHALE_ECHO gates so an off:links trial measures links alone. Edit echoes name touched symbols plus impacted callers on write/edit; the diff rides metadata for the TUI while the receipt stays one line. Grep max_results is clamped with honest truncation, skill listings are capped, JS arrows sound as their source token, and ECHOLOCATION.md documents the surfaces. Signed-off-by: AdityaVG13 <adityavgcode@gmail.com>

Relative imports now sound their leaf instead of a bare dot (from . import sib -> sib, ./server -> server), which composes with stem-shadowing when the link resolves and names the module when it does not. Removes the temporary footer-breakdown probe (its numbers landed in the PR; the eprintln tripped the print_stderr deny and flipped Lint red). Signed-off-by: AdityaVG13 <adityavgcode@gmail.com>

Child on the same route/model/tools inherits the parent's cached prompt prefix (system prompt + compacted history) as its frozen LivePrefix base, warming from the warm cache instead of going cold. Resolution is a pure deterministic gate (resolve_fork_inherit) — same route, same model, same or subset tools, child config digest must descend from the parent chain — so narrowed roles and grandchildren correctly fall back cold. No human-language compression anywhere; the child extends the parent's verbatim prefix with its own delegation message (append-only history per docs/CACHE.md), keeping prompt-cache prefix-matching intact.

Replace whole-block tool equality (which never held: parent wire blocks grow by deferred discovery while child grants are fixed and narrower) with longest byte-equal head resolution. The child adopts the parent's exact system bytes and sends the matched head on its first request; the rest of its grant stays deferred and activates on demand, so truncation costs cache bytes, never capability. Full head (inherited_full) prices shared history as hits; partial head (inherited_prefix) still prices system plus matched tools. Both sides now canonicalize through tool_to_api_json (the wire shape), so internal-only flag skew (defer_loading, allowed_callers) can't false-negative the comparison. The hot proof carries forward across append-only requests, since spawns execute before the current request's usage lands. Fresh spawns, grandchildren, resumes, route skew, and cold prefixes stay cold with distinct reasons. Trial instrumentation (CODEWHALE_FORK_TRIAL=1, default off) mirrors the decision, prefix span, history-divergence point, and child first-response cache split to stderr as JSON lines for same-binary A/B measurement; headless exec installs no tracing subscriber, so the tracing trial logs are invisible there. Measured (same-binary A/B, DeepSeek, unique histories, child first-response): true cold 0/9421 hits; primed cold 4736/9389; prefix k=3 5504/9941; full k=6 8576/13251. Inherited children reported correct results in every run. DeepSeek counts hits in 64-token blocks. Follow-ups: fork transcripts freeze at turn 1 (the live tail never rides), framing sits ahead of where the tail would (breaking the head match), grandchildren carry ~40KB all-miss transcripts (single-level v1).

The CODEWHALE_FORK_TRIAL readout intentionally writes JSON lines to stderr (headless exec installs no tracing subscriber, so the tracing trial logs are invisible there). Narrowly allow clippy::print_stderr on the two env-gated diagnostic blocks with justification, following the existing in-repo precedent. Documents the fork-prefix contract, measured benchmarks, trial procedure, and known follow-ups in docs/CACHE.md.

The tool layer hands echolocation canonical file paths while the workspace may be non-canonical (macOS /var to /private/var tempdirs, Windows verbatim paths). Three spots compared them raw and silently missed everywhere but Linux: - workspace_relative now canonicalizes both sides before giving up, restoring caller and link matches. - pod_relative_names compares in workspace-relative space instead of joining the raw workspace, restoring same-pod shortening. - Grep match paths fall back through the same canonical strip instead of rendering absolute. Verified against the three CI failures locally on macOS; Linux suites are unaffected (fast paths unchanged).

@aboimpinto

Reconcile the complete contributions from #6832 (@aboimpinto), #6867 (@hodeswildsmith455-boop), and #6805 (@LIghtJUNction) with the current Engine, provider identities, reviewed-plugin policy, and task lifecycle. Original contributor histories are recorded by subsequent resolved merges. Fix the already integrated contributor cases: snapshot corruption is an explicit unavailable/error result (#6817), malformed locales cannot select an incidental script (#6860), image metadata uses the exact uploaded bytes and respects available decoders (#6858), automation deletion waits for actual scheduler reconciliation (#6864), and blocking trust/skill reads stay off the async executor (#6869). Preserve #6857's compaction regression. Extend #6872's human-wait lifecycle guard to approval/elevation cards; retire only the matching ended parent request and refresh activity only after a delivered decision. Enforce configured finite approval deadlines in the Engine, including deadline/cancellation races and durable receipts. Serialize Native Windows ACL admission/retirement across Core processes with a logon-scoped kernel mutex, preserving exact SID/object validation. Add an actual child-process lock test; serialize DSH host tests in the existing extension-host lane. Windows execution proof remains hosted CI. Reconcile the vendored computer-use plugin with canonical main a656f67455fc while preserving Core's 0.12.1 embedding contract. Canonical b47/a656 tree passed Ubuntu/macOS/Windows source and package gates, including 28/28 Windows-focused tests and the controlled desktop fixture; this is separate from the new Engine head's CI verdict. Partial adaptation of the discovery-cache priority portion from PR #6393 by @AdityaVG13 (original ac33dd4). Preserve the best match under count and byte limits without importing the unfinished echolocation/fork design; the broader draft remains open. Validation: - npm test: 1286 passed, 0 failed, 7 skipped; web 767/767. - npm run check:web: lint, typecheck and production build passed. - Affected Rust selection: 801/803 initially passed; the two fixture/lifecycle expectation failures were corrected and each passed a focused rerun. - Additional focused Rust: approval 28/28, discovery cache 11/11, OrcaRouter synthetic catalog 3/3, and 33/33 lifecycle/API/routing checks. - Final CI-repair selection: 37/39 initially passed; the BMP feature-proxy and feature-registry summary failures were corrected; both corrected tests passed (2/2, 0 failures). - Qualified Clippy: six packages, all targets/all features, passed with the CI style allowances. Portable no-default-feature check passed; portable policy verifier 6/6 passed; formatting and diff checks passed. - Runtime contract: 55 measured metrics passed after explicit remeasurement; all 21 structural identities were unchanged. Twelve byte/token-estimate budgets account for bounded child-wait disclosure and contributor locale descriptions; no runtime field/prompt was removed to lower the budget. - Persistence budget was not qualified locally: the checker requires a clean tree and this shared checkout retains an unrelated operator file. Clean hosted CI, fresh stamped build and real DeepSeek TUI acceptance remain required before the integration PR can merge to main. Refs #6872, #6843, #6795.

@Hmbown no problem, i'll get my agents working on it right now

@AdityaVG13

Preserve all eight original @AdityaVG13 commits and reconcile their source-navigation, bounded tool-output and fork-prefix work with current main88b4c58d. Use the existing Engine, Runtime header ownership, Core serializer and opaque installed route receipt; retain policy-filtered child tools, durable protected header observations and cold fallback on mismatches. Derived source reads remain protected/contained and current async consumers run in existing blocking workers. Retain current eager core tools and the eight-name/16KiB deferred cache. The explicit seven synchronous helper sites are recorded as future-call debt under the existing checker policy, not an intrinsic worker guarantee. Add the three feature rows and derive their facts plus the own-main agent docs from the existing owners. No unrelated release/catalog/pricing/OAuth source or WIP ancestry is included. Actual local Mac evidence is on the separate combined ECD+102-path source, with exact feature selections/source custody independently bound: Summary20 Runtime tests run:20passed/0failed/176outsidefilter; Summary30 Core tests run:30passed/0failed/67outsidefilter. Original TUI gate ran636:631passed/5failed; the next coherent repair ran58:57passed/1failed. These failures remain preserved. Search cap/context/trust/path-warning cases then passed; the same eager fixture was renamed/migrated and the two-case final selection passed2/0/15417outsidefilter. Feature registry2/0/0skipped. Actual CI-flags workspace/all-target/all-feature Clippy12m19s/0diagnostics; npm540Node+772Vitest=1312passed/0failed/7skipped; generated-docs repair and web/fmt/diff passed. No new agent test function/code comment. All79 original contributor declarations remain with the explicit eager-name migration; the conditional Unix fixture may early-return. The intended42-path own-PR tree has not yet been compiled or tested; fresh exact-head hosted Ubuntu/macOS/Windows/Lint/reviews remain a required HOLD before merge. No Windows distribution/provider cache-savings/live grant or final release claim. Source branch and original authors/history remain. Refs codewhale-hq#6393

Thank you, @AdityaVG13, for the index-free source navigation, bounded tool responses and fork-prefix work—and for being willing to keep working with us after main moved. Your eight original commits are preserved. I have pushed a history-preserving adaptation to your branch using the current Engine, route identity and protected-read boundaries; the PR body explains the12 review dispositions and the limits of the local evidence.

The repaired canonical feature checks, registry, Clippy, npm and web gates passed. Fresh CI on your actual PR head is now running, so I am keeping the merge and review-thread resolutions gated on those results. The feature remains experimental for0.10.2, which has not shipped; no provider cache-saving or final Windows-package claim is being made. Thank you for giving us the source and tests to carry this forward as your own PR.

@AdityaVG13

Refs codewhale-hq#6393 The first own-head Version drift job failed its contributor-credit gate because the website list omitted @AdityaVG13, whose original source-navigation and fork-prefix work is preserved in this branch. Add their literal handle beside the existing unreleased contributor without changing product source or the credit gate. Frozen combined canonical verification: npm 540 Node plus 772 Vitest passed; 0 failed; 7 skipped. npm run check:web, fmt and diff checks pass. This exact file matches the verified source. The original failed job log is retained; fresh exact-head hosted CI, reviews and Windows owner-recovery proof remain required. No upload, release, provider call or Windows distribution acceptance occurred.

… not canonical grep_files walks the canonicalized search root from ToolContext::resolve_path but stripped matches against the raw context.workspace. Whenever the workspace path runs through a symlink (macOS /var and /tmp, symlinked project dirs) strip_prefix failed and every match came back as an absolute /private/var/... path. #6393's grep pods expose this as its macOS-only grep_pods_chart_matched_dirs_with_marks failure ("//private/var/.../net"). Strip against the canonical workspace as a fallback. Evidence (macOS, this tree): a temporary, uncommitted grep check on a tempdir workspace returned "net/server.rs" with the fix and "/private/var/folders/.../net/server.rs" without it (1 failed). Existing tools::search + tools::file_search: 41 passed, 0 failed. cargo fmt --check clean. Full workspace suite left to hosted CI.

Preserve @AdityaVG13's source-echo work. codewhale-hq#6393 intentionally appends the pod footer after the paging footer (see contract_read_appends_a_pod_footer and the "page plus paging footer first, pod footer after" case); three assertions in two older main tests still encoded the pre-echo output and failed on every OS. The macOS-only grep_pods failure was a grep path bug on main, fixed there in c6bcf78 and merged in here. Evidence (macOS, merged tree): nextest tools::file + tools::search + echolocation + budget_handback: 273 passed, 0 failed; cargo fmt --check clean. Hosted CI on this head is the full-suite gate.

Echolocation: measured baseline and next implementation slice

Thanks @Hmbown for the history-preserving integration in 2095375c and the contributor-credit follow-up in 83d01c1e. The next changes focus on echolocation while preserving that integration's protected-read and fork-route safeguards. The discovery-cache priority correction already adopted separately in b0fb5f8fc is not being presented as new work.

Completed-task baseline: main, not this PR

Before extending the feature, we measured unmodified main at 88b4c58df. Both fork and upstream main matched this commit when pinned. The release binary ran on Linux aarch64; all 4,085 tracked source blobs matched the commit before and after execution.

Protocol: first-party DeepSeek deepseek-flash (advertised as V4.1 Flash), high reasoning, 40 model steps, 120 tool calls, and 16,384 output tokens per request including reasoning. Two fixed read-only source-navigation tasks, three fresh sessions each:

T: trace CLI model-step limits through engine enforcement and distinguish the tool-call budget.
R: trace native read guards, outside-workspace authority, and symlink handling.

Tool policy, prompts, and budgets were identical across repetitions. No answer hints, source modifications, shell commands, or internal-docs evidence were supplied. Success required all four requested points to be materially correct and source-cited, assessed by manual review against the pinned source, not by exit code.

Trial	Correct	Wall s	Requests	Tools	Input	Cached input	Output incl. reasoning	USD
T1	No	52.483	13	31	631,650	529,280	6,646	$0.020930940
R1	Yes	93.469	33	52	2,084,229	1,917,184	10,193	$0.036924102
T2	Yes	50.412	14	34	737,296	636,160	6,084	$0.020729280
R2	Yes	68.111	24	31	1,501,772	1,418,875	6,837	$0.020793375
T3	Yes	50.187	15	25	511,130	457,600	6,125	$0.013077300
R3	Yes	41.873	12	19	631,561	498,043	4,756	$0.024375429

Result: 5/6 correct completions. Median successful-task time: 50.299 s for T (2/3 correct) and 68.111 s for R (3/3 correct). The failed T1 answer incorrectly treated step-budget exhaustion as unconditionally ending in failure; the report-only/no-tool path can complete. That attempt remains in the table and cost totals.

Across all six attempts: 111 model requests, 192 tool calls, 6,097,638 input tokens (5,457,142 cached; 640,496 uncached), 40,641 output tokens including reasoning, and $0.136830426 at the applicable provider usage rates.

Limits: this is a small navigation baseline, not a coding/editing benchmark or evidence of echolocation improvement. Provider cache was shared and uncontrolled, and the model is a mutable provider alias. R1 received the engine's soft-landing notice before its final answer but still passed the source check. Wall time includes tools, thinking, and the spend-forwarding transport; it is not isolated provider latency.

The earlier eight-step/non-thinking pilot produced six incomplete answers. It is preserved separately and is not used for successful-task timings. Including that pilot, aggregate usage-priced spend was $0.165399630. The September fork-prefix cache measurements also remain a separate historical experiment, not a speedup claim for the current PR.

Exact prompts, commands, source/binary identities, actual answers, grading notes, and raw provider/native receipts are retained locally; the receipt bundle has not yet been published.

Next: improve the navigation, then measure the completed work

The intended benefit is fewer searches to find relevant code, narrower useful reads, and safer use of source references, not merely a higher cache-hit percentage.

Establish and preserve the source-checked main baseline, including the failed answer and the incomplete pilot.
Qualify the updated published head (5912dc268), including the read-output repair in 63188386a and upstream grep-path repair in c6bcf78c0; rerun the focused checks and keep the budget-handback failure's attribution explicit.
Carry forward the unpublished revision-qualified Rust navigation slice (02c1922a2): actionable function/method references containing path, source window, and revision; refuse stale references rather than reading the wrong lines. Reuse bounded host observations without treating shared knowledge as access permission or as evidence already delivered to a model. The old checkpoint's tests do not qualify its eventual port.
Run the same completion protocol against the integrated implementation, with a contemporaneous control and the existing echo ablation gates. Report correctness first, then completed-task time, calls, full token cost, and echo overhead, including regressions.

New source observations stay in append-only tool/history evidence, not the session-pinned prefix. This work stays in the existing Engine and tool paths; no daemon or parallel execution system is proposed. Wider composition and impact-navigation work follows only after this slice is integrated and qualified.

This comment will be maintained as verified slices land. No current-PR speedup, cost reduction, or quality improvement is claimed yet.

PR codewhale-hq#6393 own-head Ubuntu CI 38684332452 attempt 2 reported 19173 passed, 1 failed and 34 skipped: the existing failure/timeout fixture observed one request instead of two.

codewhale-hq#6393 intentionally removes native skill file paths from the ambient index, but its unchanged runtime budget rejects the first new prompt fingerprint. Keep the complete provider-free measurement in the failing checker output so all changed identities and numeric limits can be reviewed from the exact CI source. Existing validation, budget contents and exit status remain unchanged. Validation: all 22 existing runtime-budget checker tests passed against the exact proposed script; syntax and four-line diff reviewed. Ubuntu 19,174/0/34 skipped and Windows 18,429/0/27 skipped belong to parent d991cff, not this new head. macOS and fresh hosted qualification remain pending. No local native build, provider call or budget relaxation. Canonical peer files untouched. Refs codewhale-hq#6393 Signed-off-by: CodeWhale Bot <bot@codewhale.net>

Merge current main 96ba4f8 into contributor PR codewhale-hq#6393 without rewriting its ancestry. Preserve worker ownership and late completion routing alongside the contributor's guarded header inheritance. The intentional pathless skill index shrinks the representative fixture by 56 bytes. Record the actual hosted values and four cumulative identities: seven numeric leaves decrease, four hashes change, and all other values and seven history notes remain unchanged. No ceiling is increased. Give fallback base measurements their own scratch Cargo target. Both recent runs compiled the current tree, built the base into its target, then reported 26 missing prompt_zones exports on the next current-tree compile. The exports exist in the PR. Isolating outputs prevents a base build from replacing PR dependency artifacts; the precise consumed metadata was not traced. Keep ratchet exit rules and the persistence budget unchanged. Correct only the two existing comments. Cold base rebuilds occur only after a current-tree failure. Verification: - CI 38771336339, Lint 116548295102, actual checkout 0f70b22 has the same complete tree as diagnostic head 5687729. Receipt line 2652 precedes base comparison. Root checked the raw log and checkout binding. - All 55 numeric metrics and 21 identities audited; only the seven decreases and four intended hashes differ. Old budget: exit 2. Replacement: exit 0, all 55 metrics exactly at budget. Estimated tokens 2451 -> 2437 are fixture estimates, not measured provider savings. - bash -n and ShellCheck passed; 48 existing Python harness tests passed (3 + 22 + 3 + 20). No new tests, code comments, Rust test changes or assertion weakening. - Prior fork Lint success was advisory: both actual ratchets exited 1. Fresh resulting-head native, web and budget checks remain required. No local Cargo or npm suite was run for this two-file follow-up. Raw measurement log SHA256: f60ff90e0b46345eb744106aa4c70372e0ff9553fb8e73a8f4a4d22bca4871b0 Preserve @AdityaVG13's original commits and branch. Keep the PR draft pending qualification. This is not release publication. Refs CW-6439, PR codewhale-hq#6393 Signed-off-by: Hunter Bown <hunter@shannonlabs.dev>

Preserve the contributor's original history and integrate main 248634f. This carries authoritative, isolated Runtime fixtures and settlement of stale approval/input requests, plus the earlier macOS LLVM setup and Windows startup diagnostics. The clean merge retains this PR's measured budgets and gate policies. The sole overlap adds owner_session_id to the duplicate-name fixture; the source-navigation and guarded inheritance implementation is unchanged. Main repair validation: 387 existing focused Rust tests passed, 0 failed; npm 1312 passed, 0 failed, 7 skipped; check:web passed. Exact merged-tree review preserved each PR delta and the main repair. This resulting PR head still needs fresh hosted qualification; previous runs remain historical. No provider traffic, deployment or publication. Signed-off-by: Hunter Bown <hunter@shannonlabs.dev>

@AdityaVG13 thanks for preserving the failed baseline attempt and separating source-navigation correctness from cache-hit claims. I also see that you returned this PR to draft and listed the revision-qualified navigation slice and contemporaneous completion/ablation measurements as unfinished.

For the 0.10.2 intake, should the currently published slice be considered for merge once its exact-head checks pass, with that additional work following separately, or should this PR stay draft until the full slice and measurements are ready? We will retain draft status while that scope is unresolved.

The latest history-preserving integration is 6f404da8, carrying main’s Runtime ownership/fixture repair without changing your navigation code or measured budget. Fresh CI is still running. The new web and Linux-hosted OHOS checks passed; native qualification remains pending. This is candidate work, not a shipped release or an improvement claim.

Retain the original candidate and contributor histories while qualifying the combined source in parallel with original PRs #6985 and #6989. Both contributor PRs must still land as themselves before this candidate's conditional squash. The source-navigation work in draft PR #6393 is excluded pending its author's scope decision and successful qualification. Include current main 248634f: worker ownership and late completion receipts, stale approval/input settlement, shared mock authority, isolated fixture workspaces, macOS LLVM setup and Windows clipboard launch diagnostics. Carry @henrikdukefoss's Standard Compute descriptor with Unknown billing and @shenjackyuanjie's OHOS Ninja selection and ungated CLI hashing unchanged. Resolve CI/credit/generated-document intersections, synchronize approval documentation with Engine execution IDs and captured input, and narrow the Windows 10 1607 statement to verified dynamic lookup behavior. Verification: object-only merge and authored/generated-document review; 72 feature rows and 26 documentation topics preserved; git diff --check passed. No build or native/npm test was run on this combined source. Prior source receipts remain separate; hosted exact-head qualification is required. Canonical main and its index remain unchanged. No publication is authorized. Signed-off-by: Hunter Bown <hunter@shannonlabs.dev>

@Hmbown in my opinion, I think we should leave it draft ready for the next major release depending on your timeline. I want to test and make sure that the idea is sound with some empirical data before merging.
