## Test infrastructure & refactors (2026-08-07)

- Chat service `main.go` split into 8 packages (config, auth, db, handlers, ws, media, ratelimit, metrics); `db.RedisClient` + `db.PubSub` interfaces added for mocking.
- 78 tests total (Go + frontend), all passing. Coverage: auth 97.8%, config 100%, metrics 100%, ratelimit 90.3%, ws 79.6%, handlers 47.2%, media 36.8%, db 14.3%.
- Playout: 12 tests. Frontend: vitest + jsdom, 6 user + 5 admin smoke tests.
- CI: `go test -race -cover` with a 50% coverage threshold; SQLite switched to pure-Go `github.com/glebarez/sqlite` (CGO-free, works on Windows).
- Frontend coverage enforcement: vitest v8 provider, 40% statements/lines + 30% branches/functions thresholds, `test:coverage` script + CI step.

## Backups

- `scripts/backup-db.sh` (daily pg_dump → R2, 14-day retention), `scripts/backup-weekly.sh` (weekly full dump + integrity check, 8-week retention), `scripts/verify-backups.sh` (download → temp Postgres → restore + row counts).

## Gitea self-hosting migration

- Migrated repo + CI/CD from GitHub to Gitea Actions (`git.allucanget.biz/zwitschi/linearvoid`): self-hosted runner, Container Registry convention `git.allucanget.biz/zwitschi/linearvoid/<service>:<tag>`, secrets renamed `GITEA_*` → `CI_*`.

## Streaming pipeline gaps (2026-08-10)

- Continuous R2 sync via `fsnotify` (`watchAndPublishSegments`, ~7s delay); run-ID + monotonic segment naming (`r-{ISOTIME}/seg-{seq}.m4s`); atomic manifest publication (upload `.tmp` → `CopyObject`); enriched `/health` (run_id, active_item, playlist_revision, last_segment_seq, last_r2_pub, consecutive_failures); player error recovery (5 retries, 2s→32s exponential backoff, reconnecting overlay).
- CORS on `media.linearvoid.tv` remains infrastructure-only (Cloudflare R2 config, not code).

## Bug fixes not in CHANGELOG

- **2026-08-13 viewer crash**: `index.html` was missing the `#messages` container, so `addMessage` threw `Cannot read properties of null (reading 'appendChild')` on WebSocket open/message. Restored the chat panel structure and made `addMessage` defensive.
- **2026-08-15 chat reconnect loop**: after a registered user logged in, the chat panel repeatedly filled with old messages. `connectWebSocket` left the replaced socket's `onclose` handler attached, so each intentional reconnect scheduled another reconnect and every connection re-pulled the room's 50-message history on a 3s loop. Fixed by detaching the old socket's `onclose` before closing and guarding the handler against stale sockets. Regression test added; `npm --prefix frontend test` → 58 tests passing.

## Chat improvements

- Manual smoke: viewer join/leave shows a 3s flash (not a chat row); reconnect <5s shows no duplicate; admin chat-log table has no system rows

## Playout improvements

- Test in Firefox: live playback, rebuffer/recovery, chat sync; record quirks in `docs/STREAMING.md`
- Rebuild + run playout; confirm `playlist.m3u8` lists ~12 segments at 2s each
- Manual: verify viewer latency and cache-hit behavior after the change
