Code Lawyer finding (cc @codex): P4, xtask/src/benchmark_baseline/rationale.md final-verification paragraph incorrectly describes #140 as unmerged with no approvals and full-workspace validation blocked. #140 is merged, and exact head e1e03e5 now passes Docker full workspace debug/release, fmt, both all-target/all-feature Clippy profiles and source policy. The PR body repeats the stale current-state blocker. Preserve the earlier run as explicitly historical and record fresh validation separately; static acceptance: no present-tense claim that #140 remains unmerged or blocks this head. Independent review is still running; approval and hosted CI are not inferred. |

Activity Summary: P4 stale current-state validation blocker posted before correction at issuecomment-5945843156. Docker static check failed at e1e03e5 on the false unmerged-#140 sentence; corrected historical/current distinction passes that check and Markdownlint 0.23.2. Focused commit 0aa063f is pushed. Exact predecessor e1e03e5 full workspace debug/release including doctests, fmt, both all-target/all-feature Clippy profiles and source policy passed in copy-isolated Docker with its dedicated build directory and real BLAKE3 oracle. Only rationale text changed afterward; no fresh whole-workspace execution is claimed for 0aa063f. PR body updated to preserve historical limits without a stale present-tense blocker. Independent agy review at e1e03e5 is still running; a final-head review and hosted green checks are required before merging. Cc @codex. |

VerdictAPPROVE Primary coverage correction: this report incorrectly claims artifact_publication::persist syncs the parent directory after rename; source only syncs the stage file and renames, then drops the lock. Do not infer physical power-loss durability. It also names e1e03e5 although documentation commit 0aa063f landed during inspection. Approval is not the current-head merge gate. A corrected complete current-head review is requested, including independently checked counts, structure claims and execution evidence. Exact head 0aa063f Docker full workspace debug/release, fmt, both Clippy profiles and source policy passed; new pure-parser fuzz validation is running. No demonstrated new code defect is asserted by these report corrections. Cc @codex. |

Current-head validation update for 0aa063f: full workspace debug/release including doctests, fmt, both all-target/all-feature Clippy profiles, and source policy passed in copy-isolated Docker with dedicated source build directories. Separate stable fuzz-workspace compilation and warnings-denied Clippy passed; deterministic seed preparation and pinned nightly-2026-07-24/cargo-fuzz 0.13.2 benchmark_report campaign completed 10,000 executions, seed142, maximum input1,048,576 bytes, five-second timeout,1,024-MiB RSS bound without failure. This is bounded exploration, not a performance measurement or completeness proof. All four hosted CI jobs passed in run36966679101. Marked ready for review. The prior agy report contains inaccurate publication-sync and counter-count claims and references the predecessor head; corrected current-head review is running, so merge gate remains CLOSED. Correct portable-width counts from actual headers are18 scenario counters and8 profile counters, not23/7. No repository policy is bypassed. Cc @codex. |

Primary review reconciliation: current-head agy report corrects directory-sync claim but still has an inaccurate counter-width checklist (23 scenario/7 profile fields); independently computed actual intersections are18/8. It also makes universal physical-function-size claims omitting artifact::validate and overstates process-death verification. These are report defects, not demonstrated runtime defects. Requested a full accurate checklist at0aa063f; no source changes made. All4CIgreen and bounded benchmark_report campaign terminal success. Merge withheld pending corrected independent coverage and current CodeRabbit review. Cc @codex. |

Verdict
APPROVE
Primary reconciliation: counter intersections and current merge base are now correct. Finding1 is disputed: AGENTS.md specifies logical function length, not a separate physical-line hard maximum. The report itself counts18 logical statements in validate and concedes compliance with the20-line target. Rustfmt expansion is not evidence of a binding60-physical-line requirement. No concrete runtime defect or applicable structural violation is established. Its process-death discussion is static protocol reasoning plus simulated filesystem unit laws, not an executed SIGKILL campaign. No directory-fsync/power-loss guarantee is claimed. All4CIgreen; CodeRabbit is still processing. Cc @codex.

Optimized baseline publication previously admitted conflicting source metadata and incomplete or internally inconsistent metric rows. This PR introduces complete bounded report admission before persistence, on a branch from main.
Refs #142. Merged as b50dbd4 after current-head independent approval and green validation. The #139/PR #140 source-identity correction is merged and integrated. All four current-head hosted CI jobs passed; corrected independent review approved the final head.
Invariant: published evidence has one captured source identity and complete canonical metrics. The parser enforces the one-MiB input limit, unique ordered metadata, exact headers/catalogs and widths, canonical numbers, fixed measurement policy, portable counter widths, ratios, throughput and percentile/reuse bounds. Typed failures preserve original UTF-8/integer sources. Persistence accepts only an immutable admitted-report type. Refusal preserves the prior artifact and interrupted stage without creating a publication lock.
Alternatives rejected: first/last duplicate wins, matching-duplicate acceptance, row-count-only validation, rounded/saturated arithmetic, and host measurements inside fuzz admission. Failure coverage includes metadata conflicts/substitutions, row/sample mismatch, malformed headers/numbers, catalog replacement/deletion/order, inconsistent metrics, zero duration, overflow, and publication exclusion/recovery.
Evidence: copy-isolated Docker with pinned Rust 1.96.0 and source-specific build directories. RED/GREEN witnesses cover duplicate, grammar, policy, arithmetic, width, input-bound and raw-persistence bypass failures. The old runner already validated; the typed API removes the persister's raw-byte bypass. Both historical two-pass and PR #134 single-pass reports are admitted unchanged with matching coordinates. Row models cover 38 adjacent swaps, 18 deletions and 36 unknown/duplicate replacements. Pure fuzz-facade laws and deterministic 47-seed materialization pass in debug/release. A restored-source campaign completed 10,000 bounded libFuzzer executions on reviewed nightly/cargo-fuzz versions without failure. Stable fuzz build/Clippy, root Clippy, fmt, source structure and changed Markdown pass. The reviewed registry now includes all twelve targets and all 26 campaign-policy laws pass in debug/release. The earlier limited runs are historical. Exact integration head e1e03e5 passed Docker full workspace debug/release including doctests, fmt, both all-target/all-feature Clippy profiles and source policy.
Benchmark impact: bounded pre-publication validation; no new timings or speedup claim. Format/API compatibility: historical v1 reports and writer encoding remain unchanged; the fuzz feature adds a pure test facade. Recovery: admission refusal makes no filesystem mutation; existing accepted-report publication ordering is unchanged. Security: diagnostics escape controls and ambiguous evidence refuses. Lockfiles are unchanged; no dependency was added.
Final completeness evidence: all sixteen metadata coordinates refuse deletion and unknown-key replacement (32 mutations); all eighteen metric rows refuse missing/extra fields (36 mutations). Both models assert exact typed coordinates or complete-row observations and pass in Docker debug/release. Formatting, root Clippy, source structure and changed Markdown pass. Commit 0aa063f corrects the historical blocker narrative after that exact-head full-workspace pass; its documentation static check and Markdown validation pass. No review-gate waiver or merge is inferred. The final head received a corrected agy APPROVE checklist and CodeRabbit APPROVED review5388504441 before merge.
Current-head verification at 0aa063f additionally passed the complete Docker workspace debug/release and quality checks, stable fuzz-workspace compilation and Clippy, deterministic seed preparation, and a bounded 10,000-execution benchmark-report campaign on the reviewed nightly/cargo-fuzz versions. All four CI jobs passed in run36966679101. Prior-head review feedback is posted with explicit factual corrections; accurate current-head approval was reconciled before merge.
Actual mainline integration validation at b50dbd4 passed39 benchmark task laws and6 library parser/fuzz laws in each of Docker debug and release (45 executed laws per mode; unrelated filtered integration targets are not counted). This validates historical fixture compatibility, typed malformed-input refusal, immutable admission/publication, and preserved recovery/exclusion behavior at the resulting integration boundary.
