This standalone gate change must land alone, ahead of the next merge train, so its own release bump is an isolated test of version invariance. It restores Cargo dependency/feature coverage while exempting only the workspace release version.

The artifact currently on main is already stale. The fingerprint fix prevents future version-only invalidation; code alone will not make the gate green on merge until someone regenerates the artifact on a conforming host. That regeneration is now included in this PR, together with the generated README and suite tables. Local freshness checks pass; no old measurement was relabeled as fresh.

Verified against main c1569e244a4f5a7f8f08215dbcb04e5e852e27be:

  • Both reported main runs (35605249801, 35592567279) failed solely at Public benchmark evidence freshness in lint; the same error reproduces locally.
  • The proposed version-bump root cause is not true of current main: _cargo_profile_tables already excludes workspace versions and dependencies/features. A version bump leaves the digest unchanged; so does a serde_json dependency bump. A profile change moves it. The September 1 artifact predates genuine profile changes, including static-wrapper codegen-units = 16 → 1.
  • The September 1 artifact records Ubuntu 24.04.4 LTS, host ideal-mastodon, x86_64, 16 CPUs, commit 827a92bad5a589e94e1630994185693ada903fe2. ci_public_baseline_check.py validates input fingerprints, age, schema, correctness/sample metadata, pinned runtime versions, quiet policy and generated documentation. It does not rerun or compare timings against Linux CI or require its platform to match the measurement host. A macOS artifact can therefore be valid evidence of that recorded host.

The narrow change replaces profile-only extraction with whole-root-manifest hashing, normalizing only the single-line [workspace.package].version value. It scopes normalization to that table, preserving dependency-table version fields. Existing CRLF/LF normalization remains.

Inputs that invalidate evidence:

  • All other root Cargo.toml bytes: profiles (including package overrides), dependencies/versions/features, workspace membership, edition and other metadata, comments and formatting.
  • The unchanged SOURCE_PATHS: suite TypeScript, polyglot bench.*, JSON-polyglot TypeScript, app-pattern kernels, honest-bench JSON/image generators and the Node/Perry JSON-pipeline and image-convolution workloads.
  • The unchanged HARNESS_PATHS: public-baseline-config.json (including toolchain pins, sample/warmup counts and quiet thresholds) and honest-bench expected.json.

Only the workspace release version value and the existing checkout line-ending normalization are exempted. This does not expand coverage to compiler sources, member manifests or Cargo.lock, which were already outside these input sets. No freshness migration or artifact hash rewrite is added.

Validation:

  • 15 public-baseline tests pass; the new integration tests use a temporary Git repository and the real fingerprint/validator. A version-only bump passes; profile, inline dependency, dependency-table version, feature, member and edition changes fail; reverts pass.
  • Actual CI entry-point proof against the newly measured artifact, without changing its bytes: control 0, workspace version 0.5.1637 → 0.5.1638 0, release opt-level 3 → 2 2 (benchmark inputs changed), revert 0, serde_json 1.0 → 1.1 2, revert 0. Both mutations were reverted. The earlier temporary-fixture proof is superseded by this real-evidence proof.
  • Test sensitivity: substituting main's profile-only extractor causes five regression failures; substituting raw bytes makes the version-only test fail.
  • Both release metadata bumps (initially 0.5.1635 → 0.5.1636, then 0.5.1636 → 0.5.1637 after main advanced) leave the source fingerprint unchanged.
  • 30 benchmark-gate tests pass; file-size gate and git diff --check pass.

Regeneration completed on perry-macos.local, Apple M1 / arm64, 8 CPUs, 8 GiB RAM, macOS 26.5.1, AC power (initially 41 GiB disk free). Fresh clone: ~/projects/perry-public-baseline-20260922-astra; measured commit 689b1ffbab1b9cc1825ce69d6cf7cbe50fabb168; assembled at 2026-09-22T15:36:01Z.

  • Chose a side-by-side, SHA256-verified Node v22.23.1 install at ~/public-baseline-toolchains/node-v22.23.1-darwin-arm64/bin/node; existing ~/nodebin/node remains v26.5.1. Bun is 1.3.14. No Cargo profile overrides were used.
  • The exact runner's preflight passed with 13 CPU-active samples spanning 1.14–1.71%. Every component retained the <=25% for 60 consecutive seconds gate; successful run confirmation readings were 1.8%, 1.5%, 1.3%, 1.7%, and 1.4% for the final resumed component.
  • Ran ./benchmarks/run_public_baseline.sh. The complete run reached honest-bench, where installed Zig 0.16 failed to compile std.heap.GeneralPurposeAllocator. Installed SHA256-verified Zig 0.15.2 alongside it (the version in the existing honest-bench metadata); both workloads then built unchanged. Reverified the same commit and both input fingerprints, repeated the exact quiet check, and resumed the final honest-bench leg plus the original assembler/render/check commands. The four completed components were retained at that same commit. No benchmark source, correctness oracle, sample counts, or quiet thresholds were patched.
  • Earlier attempts exposed and resolved environment issues before publication: missing esbuild produced a Node command/metadata mismatch, so isolated esbuild 0.28.1 was installed with its repository-lockfile SHA512 and the full run restarted; an auto-runtime cache stamped at the earlier branch commit was moved aside after explicit linker diagnostics. The successful measurements use the current commit throughout.
  • All 50 workloads / 1,443 raw timing samples passed validation: suite 24×3×5; polyglot 9×3×11; JSON polyglot 2×3×11; app patterns 12×3×15; honest-bench 3×3×20. Honest-bench additionally measured Rust and Zig: all 300 total rows passed its strict reference check. Both public artifact checkers and generated-document checks pass locally.
  • The runner reported four historical performance warnings (loop overhead, object creation, string concatenation, binary trees). These were retained, as were losing rows in the generated tables. Measurements describe this M1 host, not a controlled Linux-versus-macOS comparison.

Additional observed CI blocker: gap-suite shard 3 reports test_gap_cron_cronjob: pass -> parity_fail (150 tests executed, 147 passing; two other parity failures were already expected). The public-baseline unit tests passed all 15 cases in CI. Regeneration addresses the freshness failure, not this separate gap-suite failure; no parity snapshot or gate bypass is changed by this PR.

Main advanced during measurement: train 255 landed as c7cbc3c73bcffea5eaa704ffbd438047e17c2878 / v0.5.1636. This PR was rebased onto it and reserves v0.5.1637, still separately from the next train. Across that main update, the only change to the existing fingerprint input sets was the workspace version; the recorded artifact fingerprints remain valid. The evidence accurately names its measured pre-train commit 689b1ffb, not the rebased compiler. Compiler-source changes remain outside this gate’s existing input policy. The actual version/profile/dependency proof and all 15 public-baseline tests were repeated after rebase. Before rebase, the entire lint job, including public freshness, passed in CI run 35748705706. Final rebased head 6d9286d3753c8646b470d154018a6dc746c160ac is confirmed by both the remote Git ref and GitHub Git-ref API, with local freshness, mutation proofs and 15 tests passing. GitHub’s PR metadata still displays the prior head while processing the update; final-head CI is pending, not claimed green.

Holding this from the merge queue for an owner decision. The code is fine; the question is policy.

As the body says, a workspace version bump already leaves main's digest unchanged: _cargo_profile_tables reduces Cargo.toml to its [profile.*] tables. So this PR fixes no invalidation. What it does is widen the fingerprint back to the whole manifest except the version line, and that reverses #7282, whose docstring gives the reason for the narrowing: whole-file hashing let a new perry-ext-* member, a dependency bump or a [workspace] restructure invalidate the artifact without moving any measured number, and the artifact then sat 40+ commits stale on a required check.

After this PR, every dependency or feature bump and every workspace-member change goes back to reddening lint until a ~2 h quiet-host regeneration runs. That trade may be worth it (an allocator or feature flag can move a number), but it's a policy call to make explicitly, not in passing.

One coupling to flag. The regeneration now running on the mini is at 689b1ffbab, so its recorded fingerprints use this PR's hashing. If this PR doesn't land, that artifact won't validate against main's profile-only checker. If the goal is only a green gate, regenerating at a main SHA gives an artifact valid under the current scheme.

The owner approved landing this. It lands on its own, right after #10354, which is in CI now, and ahead of merge train 256.

To avoid a stale version collision, the landing commit is rebuilt on current main instead of merging the branch's own bump: the branch bumps 1635 → 1636, and main is already at 1636. The content commit takes this PR's benchmarks/public_baseline.py, tests/test_public_baseline.py and changelog fragment unchanged; none of the three has moved on main since your base. That's followed by a fresh release bump. Verified on current main:

  • tests/test_public_baseline.py: 15 OK. tests/test_benchmark_gate.py: 30 OK.
  • Your isolated test, on a real bump: source and harness fingerprints are byte-identical before and after the 0.5.1636 → 0.5.1637 bump (bb679718… / 513dba8f…). The landing refuses if they differ, and also if the bump changes any Cargo.lock line other than the workspace version.

That also settles the regeneration coupling I raised: an artifact from the run on the mini at 689b1ffbab uses this PR's hashing and will validate against main once this lands. Please commit it to main after the landing, not to this branch. This PR will be closed as landed rather than merged.

…e version (#10977)

Replaces the profile-only Cargo.toml extraction with whole-root-manifest
hashing that normalizes only the single-line [workspace.package].version value,
so dependency, feature, member and edition changes invalidate the published
benchmark evidence again while a release bump does not. Scoped to that table,
so dependency-table `version` fields stay significant.

Landed on main as v0.5.1637 (1a219558ac + 57a6d60bc6, via #11017), with the owner's approval.

The content is this branch's benchmarks/public_baseline.py, tests/test_public_baseline.py and changelog fragment, unchanged. The release bump was rebuilt on current main, because this branch bumps 1635 → 1636 and main was already at 1636. Verified on the landed tree: 15 public-baseline tests and 30 benchmark-gate tests pass, and a real 1636 → 1637 bump leaves both fingerprints byte-identical (bb679718… / 513dba8f…), which is this PR's own premise tested on its own bump.

The regenerated artifact commit (915fe7cece) was deliberately not landed: under this change's own scheme it is stale as soon as #10354 lands (source fingerprint bb679718… → 9c87723d…, because #10354 adds workspace members and dependencies to the root Cargo.toml), and it measured the tokio event loop that #10354 replaces. Regenerate once after #10354 is on main.

Closed as landed rather than merged: the landing went through #11017 so the bump could be rebuilt.

The committed artifact had been stale since 2026-09-01 (`e3bd92bf65` edited
benchmarks/suite/*.ts and polyglot/bench.*), so `lint`'s public-baseline
freshness step failed on every PR and every train, and each landing needed an
admin bypass past a red required context.

Measured in one uninterrupted run on the quiet M1 mini at b77aba6, with the
pinned toolchain the config requires (node v22.23.1, bun 1.3.14) plus esbuild
0.28.1 and Zig 0.15.2. The harness's quiet gate was re-checked before every
component: preflight 1.37-1.81% CPU, components 1.4/1.5/1.5/1.7/1.5%. 50
workloads, 1,443 positive samples, all correctness checks passed.

Regenerating had to wait for #10354: it edits the root Cargo.toml, which
#10977 put inside the source fingerprint, so any earlier run would have been
stale on arrival. Verified before committing: both recorded fingerprints equal
the ones current main computes (source 9c87723d…, harness 513dba8f…), and
`benchmarks/ci_public_baseline_check.py` reports freshness OK on this tree.

Only the three generated artifact files are committed. Warn-only suite rows
(loop_overhead +28.9%, object_create +300%, binary_trees +333%) are ms-scale
against stored history and the same rows were flagged by the previous
regeneration on this host, so they are not new.
