User description

Purpose

ci-prepush-lowend.mjs ran a fixed list of local checks unconditionally on
every push, with no change-aware routing. Reconstruct the change classifier
and i18n/content-guard routing, 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.

Scope

  • scripts/ci-prepush-classifier.mjs/.d.mts — file-based change
    classification (NO_CHANGES/DOCS_ONLY/WORKFLOW_ONLY/NON_CODE_ONLY/
    RUST_TAURI/TOOLING/TEST_ONLY/TYPESCRIPT_APPLICATION/
    DEPENDENCY_TOOLCHAIN/BUILD_CONFIGURATION/AMBIGUOUS/MIXED)
  • scripts/ci-prepush-check-registry.mjs/.d.mts — routes i18n/content-guard
    checks by matched file pattern (self-referential: changing the checker's
    own implementation file forces that check to run)
  • scripts/ci-prepush-range-resolver.mjs/.d.mts (new) — manual committed-range
    resolution and pre-push-hook evidence resolution, factored out so it's
    independently unit-testable under Vitest without importing
    hooks/shared.mjs (which pulls in dependency-state.mjs's raw
    import.meta.url path resolution — intentionally tested via node:test
    instead, not Vitest; confirmed by the repo's own existing
    dependency-state.test.mjs)
  • scripts/ci-prepush-lowend.mjs — now change-aware, guarded behind
    main()/isMainModule so the range-resolver logic stays importable

Fixes relative to the prior reconstruction attempt this is based on

  1. Fail-open manual Git range. A failed git diff on a resolved manual
    upstream range silently produced an empty-but-"resolved" file list,
    allowing an unsafe skip. Now a failed diff explicitly falls back to
    conservative full admission (rangeResolved: false), never a silent
    empty-but-complete result.
  2. scripts/coverage-thresholds.json misclassified as generic TOOLING
    despite being a resolveJsonModule import into vitest.config.ts — a
    push touching only it wrongly deferred typecheck. Now classified
    TYPESCRIPT_APPLICATION.
  3. Wires in pathEvidenceState (fix(devops): make pre-push path evidence completeness explicit #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.

Validation

  • pnpm exec vitest run tests/unit/tooling/ciPrepushClassifier.test.ts tests/unit/tooling/ciPrepushRangeResolver.test.ts — 22/22 passed
  • pnpm exec biome check on touched files — clean
  • pnpm run typecheck — clean

Summary by Sourcery

Reconstruct change-aware local pre-push admission with conservative fallbacks when change evidence is incomplete.

New Features:

  • Add change classification and file-based routing for local pre-push admission checks.
  • Add independently testable resolution of manual Git ranges and pre-push evidence.

Bug Fixes:

  • Fail closed when Git range diffs, working-tree discovery, or path evidence are incomplete instead of allowing unsafe check skips.
  • Classify coverage configuration and typed test fixtures as TypeScript-impacting changes so typecheck still runs.

Enhancements:

  • Make the low-end pre-push runner run unconditional guardrails while conditionally admitting TypeScript, i18n, and content checks based on changed files.
  • Route i18n and content-guard validation to governed files and admission-logic changes, and keep the runner importable for testing.

Documentation:

  • Document the change-aware pre-push routing and fail-closed behavior in contributor and CI guidance.

Tests:

  • Add regression coverage for change classification, conditional check routing, evidence completeness, range failures, and module execution behavior.

Chores:

  • Update documented test counts and repository metrics.

Summary by CodeRabbit

  • New Features

    • Added smarter pre-push validation that identifies checks relevant to changed files.
    • Added support for staged changes, untracked files, manual push ranges, and push evidence.
    • Added optional full-validation mode with clear pass/fail reporting.
    • Added conservative fallback validation when change details are incomplete or unavailable.
  • Documentation

    • Updated guidance for change-aware validation, conditional checks, and CI responsibilities.
  • Tests

    • Expanded coverage for file classification, validation routing, range resolution, evidence handling, and failure scenarios.

CodeAnt-AI Description

Make local pre-push checks change-aware and fail safely when file evidence is incomplete

What Changed

  • Local admission checks now run only when changed files require them, while TypeScript checks still run for application code, typed test fixtures, and coverage configuration changes.
  • Documentation, workflow, tooling, test-only, and unrelated native changes can defer unnecessary checks.
  • i18n and community-content checks now run for governed files and for changes to the admission logic itself.
  • Failed Git range or working-tree inspection, partial path evidence, and invalid manual evidence now trigger conservative full validation instead of allowing checks to be skipped.
  • Added regression coverage for change classification, check routing, range failures, evidence completeness, and command invocation.

Impact

✅ Faster pre-push checks for documentation and non-code changes
✅ Fewer unsafe check skips when Git change evidence is incomplete
✅ Type errors caught for typed fixtures and coverage configuration changes

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).

Reviewer's Guide

The PR rebuilds change-aware local admission by extracting fail-closed range/evidence resolution, classifying changed files by validation impact, routing i18n/content checks through a self-aware registry, and wiring conservative selective execution—including mandatory typecheck for TypeScript-impacting changes—into the low-end pre-push runner.

The refactoring successfully introduces change-aware routing for local pre-push checks with proper fail-safe behavior. The implementation correctly addresses the three fixes mentioned in the PR description: fail-closed git diff handling, proper classification of coverage-thresholds.json, and correct pathEvidenceState wiring. The code demonstrates good separation of concerns with testable architecture through dependency injection, and the test coverage validates the critical failure scenarios.

Hey - I've found 2 issues

Please address the comments from this code review:

## Individual Comments

### Comment 1
<location path="scripts/ci-prepush-lowend.mjs" line_range="96-97" />
<code_context>

-console.log('[local-lowend] pre-push checks passed sequentially.');
+// QNBS-v3: guard execution so this module can be imported for testing without running the CLI.
+const isMainModule = process.argv[1] === fileURLToPath(import.meta.url);
+if (isMainModule) main();
</code_context>
<issue_to_address>
**issue (bug_risk):** The `ci:prepush` package script invokes this file as the relative path `scripts/ci-prepush-lowend.mjs`, but `process.argv[1]` is then relative while `fileURLToPath(import.meta.url)` is absolute, so `isMainModule` is false and `main()` never runs. The pre-push admission command exits successfully without running any checks.

**Triggers:** When the runner is invoked through the repository's `ci:prepush` package script or another relative script path.

**Suggested fix:** Compare normalized absolute paths, for example with `resolve(process.argv[1]) === fileURLToPath(import.meta.url)`, or use a URL-based main-module check.
</issue_to_address>

### Comment 2
<location path="scripts/ci-prepush-range-resolver.mjs" line_range="27-32" />
<code_context>
+  const staged = spawnSync('git', ['diff', '--no-renames', '--name-only', '-z', 'HEAD'], {
+    encoding: 'utf8',
+  });
+  const untracked = spawnSync('git', ['ls-files', '--others', '--exclude-standard', '-z'], {
+    encoding: 'utf8',
+  });
+  return parseNulDelimitedPaths(staged.status === 0 ? (staged.stdout ?? '') : '').concat(
+    parseNulDelimitedPaths(untracked.status === 0 ? (untracked.stdout ?? '') : ''),
+  );
+}
+
</code_context>
<issue_to_address>
**issue (broader_impact):** `defaultWorkingTreeFiles` discards failures from either `git diff HEAD` or `git ls-files --others` and still returns the paths from the successful command. `changedFilesFromManualRange` then marks the result `rangeResolved: true`, allowing change-aware skips based on an incomplete working-tree file list.

**Triggers:** When either working-tree Git command fails, such as outside a valid repository, during a Git error, or because the command is interrupted.

**Suggested fix:** Return an explicit failure sentinel when either command fails and propagate `rangeResolved: false` so the runner uses full admission.
</issue_to_address>

Sourcery assessment

Needs a human reviewer. 2 findings to address first, and this changes which local admission checks run based on inferred file impact, so a routing or classification defect could let invalid i18n or community-template changes be committed without those checks. Reverting restores the old checks, but any bad content or code admitted while the refactor was active would need a separate cleanup or rerun.

Blocking findings: scripts/ci-prepush-lowend.mjs:97, scripts/ci-prepush-range-resolver.mjs:32

📝 Walkthrough

Walkthrough

The pre-push validation flow now resolves manual evidence, classifies changed files, selects applicable admission checks, and conditionally runs TypeScript validation. Public declarations, tests, and documentation cover the registry, classifier, resolver, and execution behavior.

Changes

Pre-push admission validation

Layer / File(s) Summary
Admission-check registry
scripts/ci-prepush-check-registry.mjs, scripts/ci-prepush-check-registry.d.mts, tests/unit/tooling/ciPrepushClassifier.test.ts
Keeps the registry module-local while retaining shouldRunAdmissionCheck as the public API. Range-resolver changes trigger i18n and contentGuard.
Change classification and validation decisions
scripts/ci-prepush-classifier.mjs, scripts/ci-prepush-classifier.d.mts, tests/unit/tooling/ciPrepushClassifier.test.ts
Classifies locale, community-template, fixture JSON, test, tooling, workflow, Rust, and unknown paths. It determines TypeScript and full-validation requirements.
Manual range and evidence resolution
scripts/ci-prepush-range-resolver.mjs, scripts/ci-prepush-range-resolver.d.mts, tests/unit/tooling/ciPrepushRangeResolver.test.ts
Resolves committed and working-tree paths, validates evidence, detects module entry points, and fails closed when Git results are incomplete.
Conditional pre-push execution and documentation
scripts/ci-prepush-lowend.mjs, AGENTS.md, CLAUDE.md, docs/CI.md, README.md
Runs baseline checks sequentially and conditionally runs i18n, content-guard, and TypeScript checks. It supports --full, reports status, updates validation documentation, and refreshes test metrics.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 80b18

The PR makes local pre-push validation change-aware and fail closed when evidence is incomplete, but changes limited to range resolution may still bypass required admission checks and the published declaration may omit a runtime export needed by TypeScript consumers; documentation inaccuracies also need follow-up, so merge should wait for these issues to be fixed or explicitly accepted.

Comment thread scripts/ci-prepush-check-registry.mjs
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.

Codecov Report

✅ All modified and coverable lines are covered by tests.

📢 Thoughts on this report? Let us know!

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.

Comment thread scripts/ci-prepush-lowend.mjs
Comment thread scripts/ci-prepush-lowend.mjs
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.

Comment thread docs/CI.md Outdated
Comment thread AGENTS.md
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.

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.

This PR successfully implements change-aware local pre-push admission with proper fail-closed behavior and comprehensive test coverage (22/22 tests passing).

Key security improvements verified:

  • Fail-closed behavior when git commands fail (returns rangeResolved: false instead of empty resolved lists)
  • Correct pathEvidenceState === 'COMPLETE' check (prevents trusting incomplete tag-push evidence)
  • Self-referential routing (admission checks run when their implementation changes)
  • Coverage-thresholds.json classified as TYPESCRIPT_APPLICATION (prevents skipping typecheck)

The implementation properly handles all documented edge cases including failed git diffs, incomplete working-tree discovery, partial path evidence, and invalid manual evidence. No blocking issues found.


You can now have the agent implement changes and create commits directly on your pull request's source branch. Simply comment with /q followed by your request in natural language to ask the agent to make changes.
