Consume the canonical attestation gate instead of carrying a copy of it - #32
Conversation
This repository carried its own copy of the publish-attestation scanner and verifier. That gate decides whether an artefact may reach the registry, so a false pass is the failure that matters, and a copy frozen at any point in the canonical implementation's fix sequence still admits every construction closed after that point. Measured with the fleet bypass corpus, run through this repository's own verify() against a throwaway git repository - the level CI runs. After convergence it reads seven of thirty-eight, the same seven every converged repository reports, because they all run the same published code. Every one is open in the canonical implementation rather than here, and unbraind/pm-ops#100 closes all of them. That identity is the point, not the count: before this, the repository had a posture no pm-ops release could reach. Where the scanner had a second consumer beyond the gate itself, the changelog-date verifier and its suite now import their shell helpers from pm-ops/shell-scan rather than from the deleted file. The attestation suite no longer re-tests the shell model - that belongs with the implementation - and asserts instead that this repository is still a CONSUMER: no local scanner, the launcher re-exporting the package's own functions BY REFERENCE so a wrapper cannot start a re-fork unnoticed, and the resolved gate still refusing an unattested publish.

… re-export Every reviewer on this convergence wave raised the same gap independently: re-export identity pins the IMPORTED binding, not the one runIfMain calls, so a future edit could divert only the executed path and leave every other assertion green. The entry-point test now captures what runIfMain writes and asserts it equals the package's own report(verify(fixture)) byte for byte. A local reimplementation would have to reproduce the canonical auditor's exact failure wording to pass, and reproducing it is being it. Diverting only the executed path makes this fail while re-export identity and the exit code still pass. Two smaller findings from the same round. The shebang matrix was too narrow, and now covers six states rather than four. And the shebang test could pass for the wrong reason - it depends on this file's prose naming the command it guards, so if the prose stopped mentioning it every case would read 'not shell input' and the test would go green having proved nothing; that precondition is now asserted. The fixture no longer commits: the gate discovers files through git ls-files, which reads the index, so staging is enough and committing made the fixture depend on ambient git identity configuration for no gain.
report sets exit code 1 for ANY failure, so asserting only that one occurred would let an unrelated failure - a fixture that tracked nothing, say - stand in for the unattested publish the case exists to catch. The byte comparison against the package's own report would still hold, because both sides would have made the same mistake.

Round 2 pushed. Three changes from your findings, all measured rather than asserted:
The fixture also no longer commits — the gate reads @coderabbitai full review Please re-attack. The claim now under test is that the executed path is the package's code, evidenced by output equality. If you can construct a local implementation that reproduces the canonical report exactly while not being the canonical code, that is a real hole in this argument and I would like to know. |

…e fixture A single fixture did not prove what its comment claimed. A local verifier that hardcodes that one report satisfies the byte comparison, the workflow-name assertion and the re-export identity check at the same time, while diverging on every other publish shape. Found by Greptile, reviewing the round-1 fix. The comparison now runs over four structurally different shapes, each exercising a different decision in the auditor: a plain unattested publish, an unresolved program reached through command substitution, a foreign publisher, and an attested publish that must leave the exit code alone. Matching all four across every decision would mean reimplementing the auditor, which is what this rules out. Proven against both attacks: diverting the executed path fails, and hardcoding the first fixture's exact report also fails because the other three disagree. The residual limit is stated in the test rather than implied - ESM gives no way to observe a call target from outside the module, so this is agreement across a shape space, not call-site identity, which is why the space is varied.

…hare the fixture Three round-2 findings. Greptile: the single-fixture byte comparison was satisfiable by a local verifier that hardcodes that one report - the attack was built and passed 6/6 against the old test. The comparison now runs four structurally different shapes, and the same hardcode fails because the other three disagree. The residual limit is written into the test: ESM offers no way to observe a call target from outside the module, so this is agreement across a shape space, not call-site identity. CodeRabbit: the launcher docstring still claimed the suite reproduces 'all three states' after the matrix grew to six - the same copied-text-carries-the-error pattern this convergence exists to end, this time in text written today. CodeRabbit: two sites built the same throwaway git repository. Extracted to withTrackedFixture, which documents why staging without committing suffices - the gate reads git ls-files, so a commit adds only a dependency on ambient git identity configuration. The hardcode attack was re-run after the extraction to confirm it did not weaken.

Merging. Three review rounds on this change, and every round found something the previous one had asserted rather than proved. The change. The vendored publish-attestation scanner is deleted; the gate is the canonical What review changed, in order:
Each fix was proved by building the attack it was supposed to stop. The hardcoded-report verifier passed 6/6 against the round-2 test and fails against the round-3 one. One limit stated rather than implied: ESM offers no way to observe a call target from outside a module, so the entry-path check establishes agreement across a shape space, not call-site identity. That is written into the test, because the previous comment overclaiming is what let the gap survive two rounds.

Measured, not asserted
The bypass corpus (
scripts/attest-corpus/check.shin the companion) runs 38 shell snippets through this repository's ownverify()against a throwaway git repository — the level CI runs, notauditPublishAttestation(), which skips the shebang filter and false-fails every Node script.The seven are the same seven every converged repository reports, because they all run the same published code, and every one is open in the canonical implementation rather than here. unbraind/pm-ops#100 (merged) closes all seven, so they close here with an ordinary version bump.
That identity is the point, not the count. Before this change the repository had a security posture no
pm-opsrelease could reach — including$(echo npm) publishand its backtick form, closed upstream some time ago and never going to arrive.This repository names its entry-point helper
scripts/script-launcher.tsrather thanmain-invocation.ts, so the launcher importsisMainInvocationfrom there. Copying the reference file unchanged would have failed to resolve.What the suite asserts now
It no longer re-tests the shell model — that belongs with the implementation, where one fix reaches every consumer at once. Instead it asserts this repository is still a consumer:
scripts/shell-command-scan.tspm-ops/attestationand resolves no part of the shell model locallytypeofwould let one through. That gap was found by review earlier in this wave, and the assertion is proven non-vacuous: substituting a wrapper makes it failGates
