fix(3657): skip false-fail when pristine hash drifts after GSD update (#3767)
* test(3657): RED+shape-lock for verify-reapply-patches pristine-drift Adds tests/bug-3657-verify-reapply-patches-pristine-drift.test.cjs: - Core regression: exits 0 with reason=OK_PRISTINE_DRIFT_DETECTED when on-disk gsd-pristine/ hash does not match backup-meta.json.pristine_hashes - Counter-tests: real FAIL_USER_LINES_MISSING still caught when hashes match; over-broad mode unchanged when backup-meta.json is absent; clean run reports 0 failures when everything matches - Multi-file: drift + real-failure handled independently per file Updates tests/bug-2969-verify-reapply-patches.test.cjs REASON shape-lock to include OK_PRISTINE_DRIFT_DETECTED (added by the #3657 fix). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(3657): verify-reapply-patches skips pristine when hash drifts When gsd-pristine/ is refreshed to a newer GSD version after a backup is captured, the on-disk pristine's SHA-256 no longer matches the hash recorded in backup-meta.json.pristine_hashes. Using the wrong-version pristine as the diff baseline inverts the delta: every line the upstream removed between the two versions appears as a "user-added line that must survive", producing spurious FAIL_USER_LINES_MISSING false positives (Bug #3657). Fix: - Add sha256() and readPristineHashes() helpers to verify-reapply-patches.cjs - In verifyFile(), when a pristine_hashes entry exists for the file, compare the on-disk pristine's SHA-256 against it before accepting the baseline - On hash mismatch, return immediately with status=ok and the new REASON.OK_PRISTINE_DRIFT_DETECTED code, skipping the diff rather than false-failing - When no pristine_hashes entry exists (older installer / absent backup-meta), fall through to the pre-fix behaviour (use on-disk pristine as-is) - Export sha256, readPristineHashes, and OK_PRISTINE_DRIFT_DETECTED New REASON code OK_PRISTINE_DRIFT_DETECTED is added to the frozen enum. Exit code contract is unchanged: 0 for gate pass (including skipped-due-drift files), 1 for real user-content failures, 2 for structural errors. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * chore(3657): update changeset to reference PR #3767 * fix(3657): surface drifted_files in verify-reapply-patches JSON report Extend the top-level JSON report shape with two additive fields: - `drifted: N` — count of files skipped due to pristine-snapshot drift - `drifted_files: [...]` — relative paths of those files Per-file shape is unchanged (status:'ok' + reason:OK_PRISTINE_DRIFT_DETECTED) for backward compat. Drift still exits 0; `failures` count is unaffected. This gives workflow Step 5a structured data to gate on so drifted files are no longer silently treated as a full PASS (codex adversarial-review finding 1). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(3657): reapply-patches workflow halts on drifted files instead of silent pass Insert a "Step 5a: drift check" block between the exit-code check and the failures check in workflows/reapply-patches.md Step 5a. The new block: 1. Parses `drifted` + `drifted_files` from the JSON report (added in the companion prod-code commit). 2. When DRIFTED_COUNT > 0, emits a formatted HALT message naming each drifted file and instructs the user to re-baseline before re-running. 3. Sets DRIFT_DETECTED=true and exits non-zero so subsequent steps cannot execute while drift is unresolved. Drift is a distinct third state: it is not a failure (no missing user lines were proven) but it is also not a clean pass (the diff was skipped entirely). Existing pass/fail logic for VERIFY_STATUS and failures count is unchanged. Closes the silent-skip gap identified in codex adversarial-review finding 1. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * test(3657): assert drifted_files report shape + workflow Step 5a drift check Finding 1 (BLOCKER) — three new tests in bug-3657 test file: - Single drifted file: drifted=1, drifted_files contains the file path, failures=0, per-file shape unchanged (backward compat). - Multi-file drift: drifted=2, drifted_files lists both paths, clean file absent from array. - No-drift baseline: drifted=0, drifted_files=[] always present in output. Finding 2 (WARNING) — structural test on workflow source: - Asserts Step 5a contains "Step 5a: drift check" heading. - Asserts DRIFTED_COUNT, drifted_files, and DRIFT_DETECTED are referenced (confirming the gate exists and uses the structured report fields). - Asserts drift-check block appears before VERIFY_STATUS check (exit-code is 0 for drift, so the drift check must precede the non-zero gate). Also updates bug-2969 shape-lock to include the two new additive fields (drifted, drifted_files) per the contract change in the prod-code commit. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(3657): address pr-review-toolkit + codex review + CI failures - lint-tests: add // allow-test-rule: source-text-is-the-product at file top of bug-3657 test file; the inline comment at line 477 was a prose sentence, not a file-level annotation, so the lint scanner did not recognise it as the bypass token - Windows test failures (4 subtests): normalize relPath to forward slashes before pristineHashes key lookup in verifyFile(); on Windows path.join produces backslash-separated relPath values but backup-meta.json stores keys with forward slashes, causing the hash lookup to silently return undefined, falling through to use-as-is mode and producing the same false FAIL_USER_LINES_MISSING that the fix was meant to prevent Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(tests): bump verify allowlist ceiling 9→10 for bug-3657 test file Adding tests/bug-3657-verify-reapply-patches-pristine-drift.test.cjs in the previous commit pushed the verify module from 9 to 10 test files. The lint-test-file-count gate (added in #6313baad on main) enforces that modules cannot exceed their allowlist ceiling, so all 6 test platforms plus lint-tests and coverage failed with: FAIL_EXCEEDS_ALLOWLIST: verify count=10 ceiling=9 The fix is to raise the ceiling from 9 to 10 and set issue=3767. This file does not exist on this branch yet (introduced on main after the branch diverged) so we add it here. The merged CI state will see the bumped ceiling and pass.

**`verify-reapply-patches` no longer false-fails when `gsd-pristine/` has been refreshed to a newer version** — the verifier now reads `pristine_hashes` from `backup-meta.json` and validates each on-disk pristine file's SHA-256 before using it as a diff baseline; when a mismatch is detected (indicating the snapshot was overwritten by a later GSD update after the backup was captured), the file is reported as `ok` with reason `ok_pristine_drift_detected` rather than producing spurious `fail_user_lines_missing` failures for every line the upstream removed between the two versions.

* Root cause: the verifier computes user-added lines as

* but pristine_on_disk is from a LATER GSD version than the one captured in

|
||||
*
|
||||
* Fix: when backup-meta.json contains `pristine_hashes` and the on-disk

* pristine file's SHA-256 does NOT match the recorded hash, the verifier must
|
||||
* skip the stale pristine and fall back to the over-broad mode (treating every
