The sync is byte-for-byte after known normalizations (10-space YAML indent strip, shebang strip, function-wrapper strip). The pairs are listed in `check-inline-sync.sh` (`INLINE_PAIRS`):

 **Consumer-facing reusable workflows:**
 
-- `dependency-safety.yml` — verifies the native-Dependabot-cooldown invariant on each Dependabot PR. Pipeline: extract → fallback → guard → age check → GHSA/OSV scan → scorecard → comment → labels; the verdict layer is deterministic: `failure` on age violation (when `fail_on_age_violation: true`), `error` on extraction/scan failure, `success` otherwise. Verdict translation lives in `safety-verdict.sh`. No rescan companion — verifier is single-shot per PR event.

(Renamed from `dependency-safety.yml` on `main` to force a fresh workflow registry entry; public `@v3` consumers still pin to the historical filename until a new release is cut.)
 - `tag-release.yml` — computes the next semver tag from Conventional Commits, optionally runs `bump-version-files.sh` against `.version-bump.json`, creates the tag via the GitHub Git Data API (so commits/tags auto-sign under the App identity). Requires a GitHub App key (`RELEASE_BOT_PRIVATE_KEY` secret, `RELEASE_BOT_APP_ID` var).
 - `publish-pypi.yml` — `uv build` → TestPyPI (with install verification) → PyPI via OIDC trusted publishing → GitHub Release.
 
 **Release machinery for this repo itself:** `release-self.yml` (manual `workflow_dispatch`) → calls `tag-release.yml` → calls `release.yml`. `release.yml` is `workflow_call`-only (no `push: tags` trigger) and floats the major/minor tags (`v2` → `v2.3` → `v2.3.1`). Merging to `main` does **not** auto-release; a release is always a deliberate `release-self.yml` dispatch.
