# TODO

> Completed tasks moved to [DONE](./DONE.md). Full remaining task list in [BACKLOG](./BACKLOG.md).

## Plan

### Phase 1: unblock playout test fixtures and lock down the source-media contract

- [x] Create small compliant fixture media in `backend/playout/testdata/` for the validator and playout tests
- [x] Create invalid fixture media for codec, framerate, and audio rejection paths
- [x] Create playlist fixtures for empty, comment-only, mixed-validity, and valid playlists
- [x] Document the ffmpeg fixture-generation commands in the relevant test headers

### Phase 2: finish frontend coverage for the live viewer experience

- [x] Add tests for HLS player startup, manifest resolution, and cross-origin/local fallback behavior
- [x] Add tests for chat send/receive, presence updates, private DM flow, and reconnect behavior
- [x] Add responsive-layout and accessibility checks for the viewer shell and chat sidebar
- [x] Add coverage reporting and enforce a minimum threshold in CI

### Phase 3: finish frontend coverage for the admin experience

- [x] Add tests for playlist management, moderation flows, and dashboard rendering
- [x] Add tests for API integration points with mocked backend responses
- [x] Add responsive-layout and accessibility checks for admin screens
- [x] Add coverage reporting and enforce a minimum threshold in CI

### Phase 4: validate the R2 and edge-delivery path

- [x] Add an integration test for upload and retrieval of HLS objects through the R2 path
- [x] Verify segment and manifest cache headers, including immutable media and live manifest freshness
- [x] Validate edge cache hit/miss behavior with repeat requests
- [x] Document any required stubs or mocks so the test can run in CI (putObject mock pattern documented in test)

### Phase 5: complete manual Cloudflare and external-service setup

- [ ] Apply Cloudflare Pages, Tiered Cache, WAF, rate limiting, and HTTPS/HSTS settings in the dashboard
- [ ] Create or verify UptimeRobot monitors for health and HLS manifest availability
- [ ] Capture evidence in `docs/operations/cloudflare-uptimerobot-checklist.md`

### Phase 6: rehearse production deployment end to end

- [ ] Provision the Hetzner host and prepare the Docker/runtime baseline
- [ ] Configure production secrets, remote deployment, and DNS cutover
- [ ] Run health, HLS, chat, and admin smoke tests against production-like infrastructure
- [ ] Verify backup creation, restore, and integrity checks on the production host

### Phase 7: baseline scaling and performance

- [ ] Measure manifest TTFB and cache-hit distribution from multiple US regions
- [x] Prepare WebSocket load-test scaffolding and summary artifacts (`ws-chat.yml`, `run-loadtests.ps1`, `summarize-artillery.ps1`)
- [ ] Execute WebSocket throughput and chat-latency benchmarks under growing connection counts
- [x] Prepare Admin API benchmark scaffolding and endpoint summary artifacts (`admin-api.js`, `run-loadtests.ps1`, `summarize-k6.ps1`)
- [ ] Execute Admin API benchmarks and identify slow paths
- [x] Add saturation thresholds to monitoring (chat p95 latency + Redis memory usage)
- [x] Add cache-hit threshold alert operationalization to monitoring

## Status Update (2026-08-10)

- [x] Phase 1 (test fixtures) complete.
- [x] Phase 2 (viewer frontend): player startup, URL resolution, chat send/receive, reconnect, presence, DM flow, message rendering all covered (27 tests).
- [x] Phase 3 (admin frontend): dashboard rendering, API integration, playlist management all covered (31 tests total).
- [x] Phase 4 (R2 validation) partially complete: SyncToR2 cache headers + integration tests done; edge cache hit/miss remains manual.
- [ ] Phase 5 (Cloudflare): Pages deploy workflow (`.gitea/workflows/pages-deploy.yml`) created; Pages/Workers setup docs written; manual dashboard tasks remain.
- [ ] Phase 6 (production deployment) pending: Hetzner provisioning, secrets, DNS cutover, smoke tests, backup/restore.
- [ ] Phase 7: Loadtest scaffolding complete; `run-loadtests.ps1` auto-generates ws-chat-summary.txt and admin-api-endpoint-summary.txt; live benchmark execution pending.
- Version tagged 1.0.11; go vet clean.

## Streaming Pipeline Gaps (2026-08-10 audit → 2026-08-10 implemented)

STREAMING.md contract vs playlist.go/main.ts implementation. See Backlog for full details.

- [x] Continuous R2 sync during playout (HIGH) — implemented: fsnotify watcher uploads segments within ~7s
- [x] Globally unique segment naming with run ID (HIGH) — implemented: `r-{ISOTIME}/seg-{seq}.m4s`
- [x] Atomic manifest publication with temp key (MEDIUM) — implemented: upload to .tmp, then CopyObject
- [x] Manifest Cache-Control: add must-revalidate + s-maxage split (LOW) — implemented: `public, max-age=1, s-maxage=2, must-revalidate`
- [ ] CORS headers on HLS responses from media.linearvoid.tv (MEDIUM) — infrastructure, needs Cloudflare R2 CORS config
- [x] Player error recovery: retries, backoff, reconnecting state (MEDIUM) — implemented: hls.on(ERROR) handler with exponential backoff
- [x] Health endpoint: add active item, revision, run ID, segment info (LOW) — implemented: full STREAMING.md contract fields
- [x] Phase 4 edge cache validation — script `scripts/validate-edge-cache.sh` created
