claim(mirror): Ph1+Ph2+Ph3 complete — mirrors created, hedgedoc tests, 9 recipes enrolled

Phase 1: Create 3 missing Gitea mirrors (lasuite-drive, mailu, mumble) via API + force-sync
  upstream main (f4135d78, 23309a1a, 9fa5e949). All 3 return 200/empty=false from Gitea API.

Phase 2: Author tests/hedgedoc/ (uptime-kuma template) — recipe_meta.py, functional/
  test_health_check.py (GET / → 200/302), functional/test_branding.py (brand markers),
  PARITY.md. Generic tiers cover install/upgrade/backup baseline.

Phase 3: Enroll 9 unenrolled recipes in nix/modules/bridge.nix POLL_REPOS:
  bluesky-pds, discourse, ghost, immich, lasuite-drive, mailu, mattermost-lts, mumble, plausible.
  Final POLL_REPOS: 20 entries (cc-ci + 19 recipes).

Gate Ph4 CLAIMED: operator must run `nixos-rebuild switch --flake .#cc-ci` on cc-ci after
Adversary-verifies Ph1+Ph2+Ph3. See STATUS-mirror.md for exact repro.

+# Parity — hedgedoc
+
+HedgeDoc (formerly CodiMD) is a collaborative real-time markdown editor. It is a single-service
+app backed by sqlite (default) or PostgreSQL, with a Node.js backend on port 3000.
+
+The upstream recipe-maintainer corpus (`recipe-info/hedgedoc/tests/`) does not exist, so this
+PARITY.md documents the cc-ci-authored suite as the baseline.
+
+## Recipe-specific tests (Phase mirror, ≥2 functional tests)
+
+HedgeDoc's defining behaviors:
+- Root path (`/`) responds 200 or 302 (redirect to `/login` or `/new` depending on auth config).
+- Served HTML contains HedgeDoc/CodiMD branding markers + bundled JS/CSS assets.
+
+| cc-ci file | what's verified | rationale |
+|---|---|---|
+| `tests/hedgedoc/functional/test_health_check.py` | `GET /` → 200 or 302 | Proves the app is up and routing through Traefik. A wedged HedgeDoc returns 5xx or no response. |
+| `tests/hedgedoc/functional/test_branding.py` | `GET /` HTML contains hedgedoc/codimd/hackmd markers OR bundle asset refs | Distinguishes "HedgeDoc is serving its own content" from "fallback page." A misrouted or empty backend lacks these markers. |
+
+## Backup data-integrity
+
+The default compose.yml includes `backupbot.backup=${ENABLE_BACKUPS:-true}`. HedgeDoc stores data
+in `codimd_database` (sqlite) and `codimd_uploads` volumes. The generic backup tier verifies a
+snapshot artifact is produced. Recipe-specific backup data-integrity overlay (ops.py +
+test_backup.py) is deferred; the generic tier suffices for initial enrollment.
+
+## Playwright
+
+Not yet authored. A Playwright flow would create an anonymous note, assert the content persists,
+and verify the collaborative editor loads. Deferred — the current functional tests plus the
+generic Playwright `assert_serving` pass the enrollment bar.
+
+## Deferred
+
+- Playwright note-creation + persistence flow
+- ops.py pre_backup/pre_restore with note content verification
+- PostgreSQL variant (`compose.postgresql.yml`) — current tests target sqlite (default)
