+## What & why
+
+<!-- Brief summary of the change and the motivation / linked issue (e.g. Closes #NN). -->
+
+## Checklist
+
+- [ ] **Tests** added or updated for this change — or it is a docs/config/automation-only PR (tests not applicable). Model: the integration test on `claude/issue-12` (prod-mirror DB, raw-SQL inserts, prefix-isolated, cleans up after itself).
+- [ ] **Docs** updated where relevant (App/README.md, App/CLAUDE.md, Docs/, automation/README.md, CHANGELOG.md).
+- [ ] `pnpm type-check` is clean and `pnpm test` passes (the PR check enforces both).
+- [ ] Verified the change (how: unit/integration tests, or a dev server on port 3100 against the test DB).
+
+<!--
+The "PR checks" workflow runs on every PR and hard-fails on: a code change with no
+test change, any type-check error, or any failing unit test.

+## Contribution policy (all changes via PR)
+
+**Every change lands through a pull request — no direct pushes to `master`.** This applies
+to humans and to the automated pipeline alike (the watcher already opens PRs).
+
+Each PR must include:
+
+- **Tests** for any code change. Model: the integration test on `claude/issue-12` —
+  it targets the prod-mirror test DB, anchors on existing rows, inserts fixtures via
+  raw SQL (schema-tolerant), isolates them with a unique prefix, and cleans up in
+  `afterEach`. Docs/config/automation-only PRs are exempt.
+- **Docs** updates where relevant (`App/README.md`, `App/CLAUDE.md`, `Docs/`,
+  this file, `CHANGELOG.md`).
+
+**Enforcement** — [`.forgejo/workflows/pr-checks.yml`](../.forgejo/workflows/pr-checks.yml)
+runs on every PR into `master`:
+
+1. **Test-presence gate:** a PR touching `App/app|lib|components|hooks` with no test
+   change fails. Justify genuine exceptions in the PR body for a reviewer to override.
+2. **Type-check:** `pnpm type-check` must be clean across the whole project (tests
+   included). The test suite's old type baseline was repaired when this gate landed.
+3. **Unit tests:** `pnpm test` must pass.
+
+All three are **hard** gates. `pnpm lint` is intentionally not run — it currently
+requires an interactive ESLint migration (a follow-up). Integration tests are
+type-checked here but executed against the `pelagia_test` DB by the autofix / locally
+(not in this shared CI, to avoid prod-mirror schema drift).
+
+A [`PULL_REQUEST_TEMPLATE.md`](../.forgejo/PULL_REQUEST_TEMPLATE.md) carries the checklist.
