+# Repository Rulesets — codified source of truth
+
+This directory holds the **org-wide compliance ruleset JSONs** for `petry-projects`.
+`.github` owns org-wide standards and compliance policy; its canonical home is
+`standards/`. See [`AGENTS.md`](../../AGENTS.md#organization-standards) for the
+repo-boundary rule (codified in petry-projects/.github#576) and
+[`standards/github-settings.md`](../github-settings.md#repository-rulesets) for how
+these rulesets are enforced.
+
+| File | Ruleset | Target | Enforces |
+|------|---------|--------|----------|
+| [`pr-quality.json`](pr-quality.json) | `pr-quality` | `~DEFAULT_BRANCH` | 1 approval, code-owner review, thread resolution, dismiss-stale, squash-only merge |
+| [`code-quality.json`](code-quality.json) | `code-quality` | `~DEFAULT_BRANCH` | Required status checks (SonarCloud, CodeQL, agent-shield, dependency-audit) |
+
+Both carry the two mandatory bypass actors — `OrganizationAdmin` and the
+`dependabot-automerge-petry` Integration app (id `3167543`), both `bypass_mode: always`.
+
+## Applying
+
+These files are the **desired-state source of truth**. `scripts/apply-rulesets.sh`
+creates/updates the named ruleset on a target repo to match — re-running is a no-op
+when already in sync. Rulesets live **on each repo**; editing a file here changes the
+desired state, not any live ruleset, until the applier runs.
+
+```bash
+# Preview the payload for one repo (no writes):
+GH_TOKEN=<admin-token> bash scripts/apply-rulesets.sh <repo> --dry-run
+```
+
+## Scope boundary
+
+- **Fleet-wide → here.** `pr-quality` / `code-quality` are org-wide policy.
+- **Protects an agent/skill's own assets → stays in `.github-private`.**
+  `release-channel-tags` lives in `petry-projects/.github-private` because it
+  protects that repo's own `pr-review/**` and `dev-lead/**` release tags.
+
+## Changing the required-check set
+
+Adding a required status-check context to `code-quality.json` makes it a **merge
+gate on every repo the ruleset targets**. A repo that does not *produce* that check
+is bricked (the required check never reports). Sequence any additions safely: ship
+the producing CI job fleet-wide first, then add the context here. Keep stricter sets
+scoped to the template / new repos until the fleet backfill lands.
