#1569 Phase 1 discovery (2026-05-02) found six historical credential exposures in molecule-core git history. All confirmed dead — but the reason they got committed in the first place was that the local pre-commit hook had two gaps that the canonical CI gate (and the runtime's hook) didn't: 1. **Pattern set was incomplete.** Local hook checked `sk-ant-|sk-proj-|ghp_|gho_|AKIA|mol_pk_|cfut_` — missing `ghs_*`, `ghu_*`, `ghr_*`, `github_pat_*`, `sk-svcacct-`, `sk-cp-`, `xox[baprs]-`, `ASIA*`. The historical leaks were 5× `ghs_*` (App installation tokens) + 1× `github_pat_*` — none of which the local hook would have caught even if it ran. 2. **`*.md` and `docs/` were skip-listed.** The leaked tokens lived in `tick-reflections-temp.md`, `qa-audit-2026-04-21.md`, and `docs/incidents/INCIDENT_LOG.md` — exactly the file types the skip-list excluded. The hook ran and silently passed. This commit: - Replaces the local hook's hard-coded inline regex with the canonical 13-pattern array (byte-aligned with `.github/workflows/secret-scan.yml` and the workspace runtime's `pre-commit-checks.sh`). - Removes the `\.md$|docs/` skip — keeps only binary, lockfile, and hook-self exclusions. - Adds the local hook to `lint_secret_pattern_drift.py` as an in-repo consumer (read-from-disk, no network — the hook lives in the same checkout the lint runs against). Drift now fails the lint when canonical changes without the local hook updating in lockstep. - Adds `.githooks/pre-commit` to the drift-lint workflow's path filter so consumer-side edits also trigger the lint. - Adopts the canonical's "don't echo the matched value" defense (the prior version would have round-tripped a leaked credential into scrollback / CI logs). Verified: `python3 .github/scripts/lint_secret_pattern_drift.py` reports both consumers aligned at 13 patterns. The hook's existing six other gates (canvas 'use client', dark theme, SQL injection, go-build, etc.) are untouched. Companion change (already applied via API, no diff here): `Scan diff for credential-shaped strings` is now in the required-checks list on both `staging` and `main` branch protection — was previously a soft gate (workflow ran, exited 1, but didn't block merge).
