Reviewer's GuideThe PR makes path-proof completeness explicit in PushEvidence by introducing pathEvidenceState, conservatively classifying tag-containing and invalid results as PARTIAL while retaining COMPLETE for branch-only and empty pushes. It updates the type declaration, adds focused unit coverage for all key cases, and synchronizes README test-count metadata. Flow diagram for push path-evidence classificationflowchart TD

This PR successfully adds explicit path evidence completeness tracking to the pre-push evidence contract. The implementation correctly distinguishes between complete path evidence (branch/new-branch/deletion updates) and partial evidence (any tag updates), solving the ambiguity where downstream consumers couldn't differentiate between a genuine no-op push and incomplete tag-only evidence.
Key improvements:
- ✅ Clean implementation with
pathEvidenceState: 'COMPLETE' | 'PARTIAL'inPushEvidenceinterface - ✅ Conservative logic: marks evidence as
PARTIALwhenever anyTAGdisposition exists, preventing false assumptions about path coverage - ✅ Comprehensive test coverage: 4 new test cases covering all evidence states (complete branch updates, partial tag updates, mixed updates, empty/invalid edge cases)
- ✅ TypeScript definitions updated to match implementation
- ✅ Documentation updated (test count badges in README)
The change respects the S3a/S1 authority boundary as stated, keeping scope limited to signing-core without touching local-admission routing. All 19 tests pass, Biome check is clean, and typecheck succeeds.

resolvePushEvidence() returned an identical empty changedFiles array
for a genuine no-op push and for a tag-only push that never produced
real path proof, so downstream local-admission consumers could not
tell a safe NO_CHANGES apart from incomplete evidence. Add
pathEvidenceState ('COMPLETE' | 'PARTIAL'), conservative for any tag
disposition in the update set (including mixed branch+tag pushes) and
for the INVALID/error path. Scoped to signing-core.mjs/.d.mts and its
own tests only; does not touch local-admission classifier routing.
Per this repo's comment convention, a non-trivial test-behavior change needs a why-comment. Explains why branch/new-branch/deletion updates diff real content while tag updates can't without inventing paths.

* refactor(admission): reconstruct change-aware local checks ci-prepush-lowend.mjs ran a fixed list of local checks unconditionally on every push, with no change-aware routing at all. Reconstruct the change classifier (ci-prepush-classifier.mjs), its i18n/content-guard routing registry (ci-prepush-check-registry.mjs), and wire both into the runner so DOCS_ONLY/WORKFLOW_ONLY/TOOLING/etc. changes skip irrelevant local checks while TypeScript-impacting changes still run typecheck. Two defects fixed relative to the prior reconstruction attempt this is based on: a failed `git diff` on a resolved manual upstream range silently produced an empty-but-"resolved" file list (fail-open, allowing an unsafe skip) instead of falling back to conservative full admission; and scripts/coverage-thresholds.json was classified as generic TOOLING despite being a resolveJsonModule import into vitest.config.ts, so a push touching only it wrongly deferred typecheck. Also wires in pathEvidenceState (#498): pre-push-hook evidence is only trusted as a complete file list when path evidence is COMPLETE, not just when evidenceState is RESOLVED — a tag-only push (PARTIAL) now correctly falls back to conservative full admission instead of trusting a possibly-incomplete changedFiles list. The manual-range and evidence-resolution logic lives in a new ci-prepush-range-resolver.mjs so it stays independently unit-testable under Vitest without importing hooks/shared.mjs (which pulls in dependency-state.mjs's raw import.meta.url path resolution — that file is intentionally tested via node:test instead, not Vitest). * fix(admission): close review-loop findings on change-aware checks Consolidated E1 remediation for PR #499's first review epoch, covering every current-material finding from Sourcery, CodeAnt, CodeRabbit, and chatgpt-codex-connector: - Working-tree Git-command failures (diff HEAD / ls-files --others) were silently converted to an empty path list instead of propagating failure; changedFilesFromManualRange() could still return rangeResolved:true. Both now return null on failure the same way the committed-range diff already did. - scripts/ci-prepush-range-resolver.mjs determines what evidence is trusted but wasn't in either governed check's implementationFiles set, so a resolver-only change could skip i18n/content-guard admission. Added to both, with regression assertions. - JSON fixtures under tests/fixtures/ get inferred TypeScript types (confirmed: tests/unit/services/logger.test.ts and features/project/coreEnvelope.test.ts both import one directly) and were wrongly deferred as TEST_ONLY. Scoped narrowly to tests/fixtures/**/*.json, not all of tests/, based on the actual fixture tree. - ci-prepush-check-registry.mjs exported an internal admissionCheckRegistry the paired .d.mts didn't declare; removed the export instead of widening the public surface, since nothing external consumes it. - Extracted isMainModule() as a tested pure function (was inline process.argv[1] === fileURLToPath comparison). Verified via the real `pnpm run ci:prepush` invocation that main() already executed correctly before this change (Node resolves process.argv[1] to an absolute path even for a relative `node scripts/x.mjs` invocation) — Sourcery's finding was a false positive, kept as a cheap defensive normalization rather than reverted. README test-count metrics resynced via the existing `pnpm run sync:readme` authority (6982+ tests / 577 files) rather than hand-edited, fixing the doc-metrics drift gate failure from E0. Validated: full `pnpm run ci:prepush` passes end-to-end (dependency state, toolchain, docs, CSP, desktop-import boundary, native readiness, i18n key parity/bundle/quality, content guard, typecheck), not just the targeted test/lint/typecheck subset. * fix(admission): close E1 findings and one self-identified test gap Terminal E2 remediation for PR #499, bounded to what the complete E1 review epoch surfaced plus one independently verified validation gap: - QNBS-v3 comments in ci-prepush-classifier.mjs, ci-prepush-range-resolver.mjs, and its test file wrapped onto a second physical line, violating this repo's hard one-line rule (chatgpt-codex-connector, AGENTS.md L245-254). Shortened all three to fit on one line each. - locales/** and community-templates/** files fell through classifyFile() to UNKNOWN -> AMBIGUOUS, triggering an unnecessary typecheck for i18n/content-only pushes even though shouldRunAdmissionCheck() already routes them to their own dedicated checks (Graphite). Added a NON_CODE_ROOTS classification matching the registry's own routing patterns, and included NON_CODE_ONLY in the mixed-category exemption so it composes with DOCS/WORKFLOW/TOOLING/TEST_ONLY. - changedFilesFromManualRange() correctly propagates a null workingTreeFiles() (working-tree discovery failure) to rangeResolved:false, but had no direct regression for that specific path -- only the sibling diffNames() failure was covered. Added it. README test-count metrics resynced again via `pnpm run sync:readme` (6984+ tests / 577 files). Validated: full `pnpm run ci:prepush` passes end-to-end. * docs: reconcile pre-push gate docs with change-aware admission CLAUDE.md and AGENTS.md still described pnpm run ci:prepush as running the exact CI typecheck and i18n checks unconditionally on every push -- that was accurate for the prior fixed-check-list runner, but this PR replaced it with change-aware routing (DEFERRED_TO_REQUIRED_CI for non-impacting classifications, fail-closed to full admission on incomplete evidence). Runtime and tests are correct and unchanged by this commit; only the description was stale (confirmed via chatgpt-codex-connector review findings on PR #499, verified against the actual checked-in text at this exact branch's HEAD rather than a different branch's copy). Also documents the same contract in docs/CI.md, which previously had no mention of the classifier at all. Docs-only: no runtime, test, or script changes in this commit. * docs: fix false lint claim and reconcile AGENTS.md sections Two errors from the prior documentation reconciliation commit, identified by fresh chatgpt-codex-connector review findings on that exact commit: - CLAUDE.md and the new docs/CI.md section both claimed ci:prepush runs lint unconditionally. scripts/ci-prepush-lowend.mjs has never invoked Biome/lint at all (grep confirms zero references) -- lint has only ever been the separate pre-commit hook's job on staged files, with full-repository lint being CI-owned. Removed the false claim and made this ownership explicit in all three files. - AGENTS.md's "Critical Execution Environment Warning" section (lines 32-36) still described the superseded unconditional typecheck/i18n behavior after the prior commit only updated the later "Testing Instructions" section, leaving two authoritative sections of the same file in direct conflict for the same command. Reconciled both to describe the same change-aware contract. Docs-only: no runtime, test, workflow, manifest, or lockfile changes. * docs: correct local-typecheck characterization and fix CI.md anchor CLAUDE.md described the local ci:prepush typecheck as "the exact CI typecheck" — it runs tsgo --noEmit with --checkers 1, while required CI uses --checkers 4. Also pointed dependency-verification recovery at pnpm install --frozen-lockfile, which does not update the dependency-state fingerprint; the repository's own authority for that is scripts/dependency-state.mjs reconcile. docs/CI.md linked to the "ci:prepush change-aware routing" section using a hand-guessed fragment (#ci-prepush-change-aware-routing) that does not match GitHub's generated slug for a heading containing a colon; corrected to #ciprepush-change-aware-routing.
…t 1) (#501) * feat(signing): add working-tree-vs-push divergence detection (S3b Part 1) Neither pathEvidenceState (#498) nor any other current signal proves that the content ci-prepush-lowend.mjs's local checks actually validate (everything runs against whatever is on disk, cwd: projectRoot) corresponds to localSha's exact committed tree, rather than a working tree that has drifted from it (uncommitted edits, staged-but-uncommitted changes, wrong ref checked out). Required CI remains the sole merge-safety authority regardless, so this is a local-gate trust/DX gap, not a safety hole -- and this commit closes only that gap, as a diagnostic signal, not as exact-tree validation. resolvePushEvidence() (signing-core.mjs) gains a new orthogonal dimension, workingTreeState: 'MATCHES' | 'DIVERGED' | 'NOT_APPLICABLE' | 'UNKNOWN', computed per-update via a new computeWorkingTreeState() using `git diff --quiet <localSha> --` (compares working tree directly against the commit's tree; structurally cannot see untracked files, which is exactly why MATCHES is not sufficient to prove exact-tree equivalence -- an untracked file satisfying an import that's absent from the real commit would make a local check pass when a real checkout of localSha would fail). DELETED updates get NOT_APPLICABLE (no commit to compare against); TAG updates are included on the same terms as branch updates via the same call (git's own revision parsing transitively peels a tag to its target), not excluded as an earlier draft had them -- a diverged tag push is now reported instead of silently unreported. Aggregation precedence: DIVERGED > UNKNOWN > MATCHES > (NOT_APPLICABLE only when no relevant update exists, e.g. an all-deletions push). computeWorkingTreeState() never throws -- it maps any runGit() failure (spawn error, timeout) to UNKNOWN internally, and critically checks result.error before trusting result.status, since runGit's own `status: result.status ?? 1` fallback makes a killed/failed subprocess indistinguishable from a genuine "differences found" exit code 1 unless the caller inspects error first. This keeps the new diagnostic fully isolated from resolvePushEvidence's existing canonical try/catch: a diagnostic failure can only ever produce workingTreeState: 'UNKNOWN' on the RESOLVED path, never evidenceState: 'INVALID'. This matters because ci-prepush-range-resolver.mjs's resolveManualEvidence() throws whenever evidenceState !== 'RESOLVED' -- without this isolation, a transient git timeout on the new diagnostic would have turned otherwise-valid, already-verified #494/#498 evidence into a hard pre-push rejection. Propagated through resolveManualEvidence()'s evidence-file path unchanged; the manual/no-evidence-file path (changedFilesFromManualRange, direct `pnpm run ci:prepush` invocation) reports NOT_APPLICABLE, not MATCHES -- there is no localSha and no push event in that mode, so no comparison of any kind happens, and claiming MATCHES would assert an equivalence that was never checked. ci-prepush-lowend.mjs reports a non-blocking, informational line only on DIVERGED or UNKNOWN (MATCHES/NOT_APPLICABLE stay silent) -- deliberately not coupled to the existing `full`-admission escalation lever, since divergence and incomplete-change-evidence are different failure modes with no shared remedy. Deliberately not implemented in this slice (reserved for Part 2, an isolated-localSha-worktree exact verification mechanism to be designed fresh against then-current main): MATCHES is never treated as a skip condition for exact verification anywhere in this codebase, in this commit or otherwise -- proving tracked-content equivalence sufficient to safely skip real verification would require also ruling out untracked/gitignored drift, which is exactly what an isolated worktree proves and a cheap diff cannot. Tests: computeWorkingTreeState's runGit-error-vs-status-1 distinction (the exact ambiguity this commit exists to close) tested directly via injected runGit results; the UNKNOWN-does-not-mutate-evidenceState regression proven directly, not just asserted in prose; tag inclusion, deletion/manual NOT_APPLICABLE, and aggregation precedence (including a mixed DIVERGED+UNKNOWN and MATCHES+UNKNOWN case) all covered deterministically with no real git subprocess in the new tests. Four pre-existing resolvePushEvidence tests updated to inject worktreeMatchesCommit so they stay git-subprocess-free rather than incidentally exercising the real default against fake SHAs. README test-count badges resynced via `pnpm run sync:readme` (578 files / 6997+ tests). Validated: full `pnpm run ci:prepush`, `pnpm run lint`, `pnpm run typecheck` (4-checker), and both targeted test files all pass. * fix(signing): prevent an injected runGit throw from escaping computeWorkingTreeState The default runGit() never throws (spawnSync failures are captured into result.error, not thrown), so this was unreachable through the real production call path. But computeWorkingTreeState() is an exported function with an optional dependencies.runGit override, and its whole contract -- documented in its own QNBS-v3 comment and this slice's commit message -- is that it never throws, so a diagnostic failure can never corrupt canonical evidence validity via resolvePushEvidence's outer try/catch. A future caller (or test) providing a runGit-shaped dependency that throws instead of returning {error} would have silently broken that guarantee. Wrap the call in its own try/catch and return UNKNOWN, matching the existing handling for a returned result.error. README test-count badges resynced via `pnpm run sync:readme` for the added regression test (578 files / 6998+ tests). Validated: full `pnpm run ci:prepush`, `pnpm run lint`, `pnpm run typecheck` (4-checker), and both targeted test files all pass. * docs(signing): make computeWorkingTreeState's tracked-content-only scope explicit inline chatgpt-codex-connector correctly observed that an untracked file can make git diff --quiet <sha> -- report MATCHES even when that file is absent from the pushed commit (e.g. an untracked ambient .d.ts satisfying an import the real commit is missing). This is not a new gap -- it is the exact, deliberately-scoped limitation this slice's design already reasons through: MATCHES is documented (commit message, PR description, the report() wording in ci-prepush-lowend.mjs) as "no tracked-content divergence detected", never "verified"/"validated", and is never used anywhere as a skip condition for real verification. Widening this check to also flag any untracked file (e.g. via `git ls-files --others --exclude-standard`) was evaluated and rejected: it would reintroduce exactly the false-positive-on-an-unrelated-scratch- file problem this design avoids by construction today (a benign WIP file anywhere in the repo would mark every push DIVERGED, making the signal noisy enough to lose developer trust), and closing the gap soundly would additionally require ruling out gitignored/generated- artifact drift -- at which point the "cheap detector" has grown into the isolated worktree that is Part 2's job, not Part 1's. Added a one-line inline comment at the exact call site making this scope boundary explicit in the code itself, not only in the commit message and PR description, since a reviewer found it non-obvious enough to flag independently. No behavior change. Validated: full `pnpm run ci:prepush`, `pnpm run lint`, `pnpm run typecheck` (4-checker), and both targeted test files all pass.
… isolation Consolidated remediation for the #502 review epoch (Sourcery, CodeRabbit, chatgpt-codex-connector). Root cluster A -- fingerprint representation: - defaultReadFileAtRef decoded git-show output as UTF-8 before hashing, while calculateDependencyFingerprint hashes raw filesystem bytes. A manifest with invalid UTF-8 bytes hashed differently on the two paths even when identical, reporting DIVERGED instead of MATCHES. Fixed by reading git-show output as a raw Buffer (spawnSync's default) instead of decoding it, so both paths hash the same bytes. - Separately, a core.autocrlf=true checkout hashes CRLF working-tree bytes while the git blob is LF-normalized, producing a false DIVERGED for otherwise-identical manifests. Fixed with a binary-safe CRLF->LF normalization (latin1 round-trip, lossless for all 256 byte values) applied uniformly to both fingerprint paths inside the shared hashManifests -- one canonical representation, not two competing authorities. Scoped to this repo's always-text dependency manifests (package.json/pnpm-lock.yaml/pnpm-workspace.yaml/patches); no .gitattributes change. - Both regressions are proven with deterministic byte-level tests: invalid-UTF8-byte fingerprint identity, and CRLF-vs-LF fingerprint identity. Root cluster B -- diagnostic isolation: - An injected worktreeMatchesCommit or dependencyStateForRef that throws propagated through resolvePushEvidence's canonical try/catch, turning a diagnostic-only failure into evidenceState: INVALID -- otherwise- valid #494/#498 evidence would be rejected outright. Fixed with a safeDiagnostic wrapper at both call sites (TAG and NEW_BRANCH/UPDATED) so a throw maps to the dimension's own UNKNOWN state, symmetrically for both diagnostic dimensions. Regression tests added for each. False positive: CodeRabbit's "duplicate const shared declaration" claim (tests/unit/signing.test.ts) does not match current HEAD -- there is exactly one `shared` declaration per test scope; the file already typechecks and lints clean. No change made; will reply with this evidence and resolve the thread.
