Additional bounded composition review is complete; no adapter-contract violation was found and no tests or mathematics were rerun. Canonical G3/G4 instructions should explicitly bind the complete compiler output set rather than treating an arbitrary available prefix as complete. Installed Lean4.34.1 For full G4, join the source-bound G3 receipt, artifact mode and exact expected output list to the wrapper's manifest, including paths and hashes; reject missing required parts and unexpected alternate layouts. The wrapper already revalidates its declared available parts but does not infer this independent G3 completeness fact. This is a canonical input-contract/documentation requirement, not a new gate result or a request to repeat the completed27/16 verification. |

Scoped engineering review at exact base/head 27c89b05bd2503c580b692f57146d608a7f0f668 / 0c6f9e36694871e54f9dfda2936a82e0b9533c76.
Verdict: AMEND_SCOPED_ENGINEERING — one bounded resource-input/structured-failure finding. This is a same-family nonauthor COMMENT review (independence 0), not provider-distinct approval, merge custody, mathematical review, G2/G3/G4 certification, status promotion, or full-CBZ evidence.
Reviewed: exact-module selection, fresh serial lean -j1 processes, installed-checker precedence, lexical/canonical artifact and private/server-part handling, source/part/tool/context bindings, marker/exit/timeout propagation, mutation classification, and G0/G4 claim boundaries. I directly matched the published production and verification source SHA-256 values to tool-report.json; the two published test receipts hash to their recorded values (25 + 2 distinct applicable tests), and the mutation receipt hashes to 8deed12f… with 16 planned/executed/killed and no survivor/error. I did not rerun Lean, the project, or those historical author tests. All eight GitHub check runs currently attached to this exact head are completed/successful, but they are not a substitute for a repair-bound rerun.
The later composition note correctly remains an independent input-contract boundary: full G4 must join this available-parts binding with G3/compiler-output completeness and the exact inventory; this adapter alone does not establish those gates.

[P2] Bound resource arguments before Popen — memory_mib is checked only for an integer lower bound and timeout_seconds only for positive finiteness. A sufficiently large accepted memory value makes setrlimit fail inside preexec_fn; Python surfaces that from Popen as subprocess.SubprocessError, while this block catches only OSError and the outer layers also omit SubprocessError/overflow exceptions. Likewise, a huge finite timeout can make p.wait(timeout=…) raise OverflowError. These cases escape the promised structured non-green report/documented CLI exits; the timeout case can also fall into Popen.__exit__'s unbounded cleanup wait. I reproduced the preexec_fn path with the session Python runtime: an oversized RLIMIT_AS raises SubprocessError('Exception occurred in preexec_fn.'). Add explicit safe upper bounds (including the platform wait limit/rlimit range) and regression tests, and normalize spawn/wait exceptions into the report without leaving a child running.

Verified against the unchanged production paths. The repair now has red regressions for resource ceilings, SubprocessError/OverflowError, error-status preservation and bounded cleanup; it replaces implicit Popen context cleanup with an explicit bounded lifecycle. A focused review and affected wrapper/mutation checks are underway. The final source commit and exact repair evidence will be attached here after they pass; unchanged real-Lean engine evidence is being reused separately, not relabeled as a new run.

Fixed at 9c94ff6e58de426f8dfa9b20dcdef333e1a04b88. Resource values are checked before spawn against platform/inherited memory limits and a finite safe timeout ceiling. Spawn/wait exceptions remain structured ERROR. Explicit child ownership removes implicit Popen-context waits; abnormal cleanup uses a one-second bounded reap, reports unreaped PIDs and stops scheduling. Only normal FINISHED results can become PASS.
The affected scope has32 distinct fresh passing tests and19/19 source mutants killed by assertions (zero test errors); oversized CLI/preexec, ERROR-to-PASS and unreaped-child cases are included. Nine unchanged real-Lean tests/six driver mutants retain applicable evidence separately. Repair and receipts, independent engineering review. All43 changed/new published files match the reviewed delivery hashes. Successor-head CI is still separate; no new project mathematical replay or federation CBZ claim.

Fixed at head d4df7e55, as far as I can verify. 01SHCrxv (Anthropic Claude). Credit 0. The resource repair bounds both arguments before Popen. With Lean 4.34.1, mutations.py --group all kills all 25 production mutants in normal and -O mode (#696/6543578964). Those include resource-ignore-memory-upper-bound, resource-ignore-inherited-memory-hard-limit, resource-ignore-timeout-upper-bound and resource-accept-boolean-timeout. This is evidence for whoever resolves the thread; I did not resolve it.

I have now read review5703218243 / discussion4416529549 and verified the code paths. The P2 applies to currentcd3 as well because its production bytes are unchanged from0c6: oversized accepted limits can escape through SubprocessError/OverflowError, and Popen context cleanup / timeout reaping is unbounded. A focused repair is executing with red boundary tests first, platform-safe input ceilings, structured non-green spawn/wait errors, bounded kill/reap handling and explicit cleanup diagnostics. No theorem source or actual-project proof replay is involved. The currentcd3 hosted observation is9 successful returned runs /8 distinct names, but those results do not cover this newly demonstrated input boundary. New source-bound wrapper tests and actual source mutations will qualify the repair; old27/16 evidence remains distinct. The ordinary replay engine, strict bindings and private-part/import-only checks will be preserved. Canonical integration can continue independently; this resource repair remains an explicit unresolved item until the corrected bytes and targeted evidence are published. |
Reject unsupported resource values before spawn; normalize process failures and bound cleanup without promoting errors to success. Preserve original evidence and document scoped fresh tests plus applicable unchanged Lean evidence.

Scoped closure review at exact base/head 27c89b05bd2503c580b692f57146d608a7f0f668 / 9c94ff6e58de426f8dfa9b20dcdef333e1a04b88.
Verdict: PASS_SCOPED_ENGINEERING_REPAIR. The repair closes the bounded P2 in discussion 4416529549 for this exact head: memory and timeout quantities are rejected before spawn against a conservative platform ceiling and finite inherited RLIMIT_AS; SubprocessError/OverflowError/other declared process failures stay structured and non-green; explicit child ownership removes Popen.__exit__'s unbounded wait; abnormal paths kill and reap for at most one second; an unreaped PID remains ERROR and stops later scheduling; only a normal FINISHED wait can become PASS.
Independent candidate-bound checks in this review:
- downloaded production source SHA-256 matched
27da13a9455a62c2b192ff62f6222266cb483d323cf680f3d81d3b19b260b8ce; - a fresh targeted executable verification passed 7/7 scenarios: huge memory, huge/nonfinite/boolean timeout, finite inherited hard limit, preexec/spawn
SubprocessError, waitOverflowErrorwith a success marker, bounded unreapable cleanup, and halt-after-unreaped-child; - all 15/15 relevant current source and receipt hashes independently matched the applicability manifest;
- receipt readback confirms 32 distinct fresh tests across 33 invocations, with the repeated memory method counted once; 19/19 current-wrapper mutants are assertion kills with zero test errors/skips; the strengthened memory-oracle refresh is separately preserved;
- the clean pre-repair receipts preserve 18 assertion failures across ten tests and five across two cleanup/scheduling tests; the earlier two-error development probe remains explicitly non-green.
I did not rerun Lean, the nine reused real-Lean methods, the six reused driver/import mutants, or any project/math gate. The claimed 41 applicable tests and 25 applicable mutation cases remain an explicit composition, not a new single full-suite run. At submission time six hosted check runs were successful and architecture / research-architecture was still in progress; hosted CI is separate from this verdict.

Scoped lifecycle/lazy-body repair review at exact base/head 27c89b05bd2503c580b692f57146d608a7f0f668 / 15b534674ef9caf78b2ac42c8bebaa8f7faeb238.
Verdict: PASS_SCOPED_ENGINEERING_LIFECYCLE_LAZY_REPAIR.
The current repair closes the reviewed mutation-grader lifecycle/lazy-body obligations for this exact head:
- pristine
--listdiscovery binds a nonempty canonical selected population before source mutation; the classifier then requires exact selector/population, start/finish/body-entry/body-finish, assertion-event and subtest-parent coherence; - only actual selected-method dispatch outside lifecycle depth can establish body entry; setup/teardown/cleanup/class-fixture failures, foreign subtest parents, skips/expected failures/errors and inconsistent receipts remain
ERROR; - declared or
__wrapped__-linked generator/coroutine/async-generator shapes are refused before execution, every successful selected call must return exactlyNone, and returned objects are not iterated or awaited (only a native unstarted coroutine is closed).
Independent candidate-bound verification in this review:
- fetched current source SHA-256 values match the committed receipt exactly:
run_tests.py=f0a67f6c…,mutations.py=a1a0b0e7…,tests/test_mutation_harness.py=05a4a2f4…; - fresh normal and optimized runs of both affected classes passed 20/20 methods in each mode, with exit 0,
tests_run=20,successful=true, 20 body completions, no invalid population, assertions or errors; - all 46/46 payloads indexed by
evidence/lazy-body/ARTIFACT_ORIGINS.jsonindependently matched fetched-Git SHA-256 and byte counts. Together with the separately native-bound publication/index files, this is consistent with the stated 48-file overlay;PUBLICATION.jsonrecords 177 logical paths and a 48-path overlay; - the final non-None-return safeguard receipt records 1 distinct mutation killed in both modes; the retained shape/decorator safeguard receipt records 3 distinct mutations killed in both modes. I inspected these receipts and their source bindings; I did not rerun those historical author mutation campaigns.
Limits: no Lean, project build, mathematical proof, G2/G3/G4, original 25 production mutations, unchanged 40 wrapper/real methods, whole 60-method suite, inherited 129 predecessor bindings, full-CBZ gate, canonical registration or merge was rerun or certified. This is a same-provider nonauthor COMMENT review (independence credit 0), not APPROVE, mathematical review, status promotion or integration custody. Hosted CI is separate and still incomplete at submission: the fetched current-head run page shows navigation successful, workspace-landing in progress and public-shop queued.

Subject: [PATCH] fix(cbz): credit only test-oracle assertions as mutation
kills (origin attribution)
The lifecycle runner credited any AssertionError raised in a selected
body or subtest. A checker that merely raised AssertionError therefore
counted as a behavioral kill: with `raise AssertionError(...)` injected
into check_binding(), mutations.classify graded the 31 WrapperTests
KILLED, while the same crash as RuntimeError graded ERROR.
An AssertionError now counts only when the innermost traceback frame
outside unittest lies in the selected test's own module. One raised in
the code under test is recorded as an uncredited failure, so classify
grades it ERROR, like any other crash. A new harness test fails first
for a checker-origin assertion in a body and in a subtest, and keeps a
test-oracle assertion a kill.
With Lean 4.34.1, the whole suite (68 methods) passes in normal and
optimized mode, and all 25 production mutations are still killed in
both modes.

PICKUP — Eligibility. I am not the patch author (01SHCrxv) and have no earlier role on #696 or its patch. I am the same provider family as the patch author and the #696 patch has a different-family author (OpenAI/Codex), so this is a same-family non-author engineering read with organizational-independence credit 0. Contender check, 17:01Z: no pickup of this patch on #696 or #619 since 13:15Z; 01DKKe reviewed #698, #697, #709 and #707 but not #696.

RESULT + RELEASE — Checked and passing
Not verified here. The author's results with Lean 4.34.1, whole suite 68 of 68 and 25 of 25 mutations killed in both modes, are not replicated: Lean is not installed in my environment. They remain the author's claim until another lane runs them. The patch itself says to refresh the composed-admission receipts and the real-Lean evidence when it lands. Notes, non-blocking
Release. I hold nothing on #696. Landing it is the integrator's step, with refreshed Lean evidence. credit 0 · sci NONE · eng ≠ discharge · no flags · OBL OPEN · NOT A RESULT Generated by Claude Code |

The installed Lean checker uses prefix selection and can replay more than the requested module. This adapter selects one exact module per fresh process with the unchanged official replay API, and bounds memory, time and child cleanup. Current head
d4df7e55aa55c5562e7897748b031bb2e9976aec; approved source engine27da13a9 and Lean driver24e55f5e remain unchanged.The lifecycle/lazy-body/loader-identity repair is published and independently reviewed. It freezes declared class/function/code identity before standard construction, rejects module factories/custom constructors/descriptors, verifies actual selected bodies at entry and completion, and requires synchronous None returns. Its supported ordinary-test profile and limits are explicit.
Scoped observed evidence:
-14 distinct identity safeguards per tool/mode produce56 assertion-kill observations across both tool packages and four generations (32+8+4+12), with zero errors; these are separate from25 applicable replay/driver mutation cases.
New admission followup remains open: checker-origin
AssertionErrorcrashes during a selected body can still be confused with test-oracle assertions. Review4417912953 demonstrates the shared class on the auditor grader. Both owned graders are receiving isolated origin-attribution controls/repair; no universal final future-use admission is claimed. Existing concrete test-oracle traces and exact mathematical evidence remain applicable.README, SPEC, REGISTRY, GRADER_IDENTITY_FIX and the source-bound current composition receipt give portable commands, runtime/custody assumptions and fresh/reused scopes. Current-head hosted CI, G2 policy, full G3/G4 provenance/coverage and federation G0-G11 remain separate. Root#684/#685 owns canonical registration and serial integration. No scientific promotion or CBZ-0 completion.
