- Frontend: 45 tests pass (2 files), test:coverage meets thresholds (22.92% / 18.44% / 19.01% / 25.42%)
- Edge cache validation script `scripts/validate-edge-cache.sh` exists.
- Remaining: CORS on media.linearvoid.tv (Cloudflare R2 bucket CORS config, not a code change). Phases 5-7 are manual/infrastructure only (Cloudflare dashboard, Hetzner provisioning, live benchmarks).
## 2026-08-11
- Consolidated all development tasks from `DEVELOPMENT.md` and `.github/instructions/TODO.md` into `.github/instructions/BACKLOG.md` as the single source of truth. `DEVELOPMENT.md` now obsolete and removed. `TODO.md` references `BACKLOG.md` and `DONE.md`.
- Fixed R2 endpoint validation in playout service (`backend/playout/src/playlist.go`):
- Added `isR2Configured()` checking all four required env vars (`R2_ENDPOINT`, `R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, `R2_BUCKET_NAME`).
- `initR2Client()` now returns a clear error if R2 is not configured instead of creating an S3 client with an empty endpoint.
- Segment watcher (`watchAndPublishSegments`), `syncLatestToR2()`, and `publishManifest()` are now guarded by `r2Client != nil` — no error spam when R2 is unavailable.
- Playout gracefully degrades: local HLS via nginx works without R2.
- Updated `.gitea/workflows/cd.yml` "Prepare environment" step to include all R2* variables sourced from Gitea secrets (`R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, `R2_BUCKET_NAME`, `R2_ENDPOINT`, `R2_ADMIN*\*`), Cloudflare variables (`CLOUDFLARE_API_TOKEN`, `CLOUDFLARE_ACCOUNT_ID`), and frontend public URL variables.
- Updated `docs/DEPLOYMENT.md` "Environment File" section: replaced vague "Cloudflare/R2 variables" bullet with explicit variable lists and added a new "Gitea Secrets" table documenting all 15 required secrets.
- All playout tests pass (20 tests), `go vet` clean.

# BACKLOG
> Consolidated from `BACKLOG.md`, `DEVELOPMENT.md`, and `TODO.md` on 2026-08-11.
## Remaining from 2026-08-11 (summary)
- **Test Fixtures**: media + playlist fixtures created; ffmpeg generation commands documented in test headers
- **User Frontend Tests**: video player, chat integration, responsive, accessibility, coverage
- **Admin Frontend Tests**: playlist UI, moderation UI, metrics dashboards, coverage
- **Cloudflare R2 Integration Test**: upload + cache header validation done (SyncToR2 with CacheControl + ContentType); edge cache hit/miss validation remains manual
- **Cloudflare Config**: Cloudflare Pages deploy workflow and setup docs created; manual dashboard setup (Tiered Cache, WAF, rate limiting, HTTPS/HSTS) remains pending; Pages project must be created in dashboard first.
- **External Services**: UptimeRobot monitors + alerts
- **Production Deployment**: Hetzner provisioning, CD pipeline, DNS cutover, smoke test
- **Scaling & Performance**: TTFB baseline and live benchmark runs still pending; loadtest scaffolding now includes Artillery/k6 helpers with auto summaries plus worksheet field mapping; chat p95, Redis saturation, and cache-hit threshold alerting are implemented

# TODO
> Completed tasks moved to `.github/instructions/DONE.md`. Full remaining task list in `DEVELOPMENT.md`.
> Completed tasks moved to [DONE](./DONE.md). Full remaining task list in [BACKLOG](./BACKLOG.md).
## Detailed Implementation Plan
## Plan
- [x] 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 1: unblock playout test fixtures and lock down the source-media contract
- [x] 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
- [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
- [x] Phase 3: finish admin frontend coverage
- [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 2: finish frontend coverage for the live viewer experience
- [x] 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)
- [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
