## 2026-08-07

- Completed runtime validation section from TODO.
- Runtime video normalization tests executed in running `linearvoid-playout` container using ffmpeg/ffprobe.
- Verified normalized outputs for MOV, MKV, VFR, and 5.1 inputs: `h264`, `yuv420p`, `30/1`, `aac`, `48000`, `2 channels`.
- Concat continuity check passed with `CONCAT_OK`; output duration `25.344667` seconds.
- Responsive viewport test on live viewer (`390x844`, `412x915`) detected 8px horizontal overflow from `100vw` usage in viewer container styles.
- Fixed overflow in source by changing `.lv-body` and `.viewer-shell` width from `100vw` to `100%` in `frontend/src/style.css`.

  - Admin session endpoint returned 200 before and after Redis restart.
  - Presence key survived Redis restart in test-lab configuration.
  - Redis health returned to `healthy` post-restart.

  - `CHANGELOG.md`

## 2026-08-07 (continued)

- Completed documentation half of recovery runbook TODO item.
- Expanded `docs/incident-runbook.md` with quarterly DR drill: prerequisites, outage simulation, restore validation, pass/fail criteria, and evidence template.
- Split TODO item into:
  - documented drill (`[x]`)
  - manual rehearsal execution (`[ ]`)
- Updated `CHANGELOG.md` with incident runbook drill documentation entry.

## 2026-08-07 (continued 2)

- Added manual operations checklist `docs/operations/cloudflare-uptimerobot-checklist.md` for Cloudflare + UptimeRobot task execution and evidence capture.
- Linked checklist from `SETUP.md` Cloudflare section and TODO manual sections.
- Did not mark manual dashboard items complete; checklist is preparation only.

## 2026-08-07 (continued 3)

- Added `docs/operations/scaling-performance-playbook.md` covering manifest TTL tuning, TTFB baseline method, WebSocket/API benchmarking approach, cache ratio tracking, capacity triggers, and Phase 2/3 plans.
- Updated TODO and BACKLOG to mark playbook creation done while keeping execution/measurement tasks pending.
- Linked scaling playbook in `README.md` resources.

## 2026-08-09

- Added WebSocket benchmark summary helper `scripts/loadtest/summarize-artillery.ps1`.
- Updated `scripts/loadtest/run-loadtests.ps1` to auto-generate `ws-chat-summary.txt` for `ws` and `all` scenarios.
- Updated `scripts/loadtest/summarize-k6.ps1` to produce pipeline-friendly output and integrated automatic `admin-api-endpoint-summary.txt` generation.
- Expanded `scripts/loadtest/README.md` with PowerShell-first artifact capture and helper usage for both ws and admin scenarios.
- Updated `.gitignore` to ignore loadtest artifacts (`artifacts/` and `scripts/loadtest/artifacts/`).
- Added artifact-to-worksheet field mapping section in `docs/operations/scaling-performance-playbook.md` so ws/admin worksheet entries map directly to generated summary files.
- Updated `docs/DEVELOPMENT.md` and `.github/instructions/TODO.md` to mark ws/admin benchmark scaffolding complete while live benchmark execution remains pending.
- Added `CHANGELOG.md` entry `1.0.10` summarizing loadtest helper automation and playbook mapping updates.

## 2026-08-09 (continued)

- Completed Phase 1 (test fixtures): documented ffmpeg fixture-generation commands in `playlist_test.go` header comments (valid_720p30, invalid_h265, invalid_24fps).
- Completed Phase 4 (R2 integration):
  - Enhanced `SyncToR2` in `playlist.go` to set CacheControl + ContentType based on file extension:
    - `.m4s`, `.ts`, `.mp4`, `.m4a` -> `public, max-age=31536000, immutable` + `video/MP2T`
    - `.m3u8` -> `public, max-age=2` + `application/vnd.apple.mpegurl`
    - unknown extension -> no cache headers
  - Added three tests: `TestSyncToR2` (segment upload with cache verification), `TestSyncToR2_ManifestCacheHeaders` (manifest upload), `TestSyncToR2_NoCacheHeadersForUnknownExt` (unknown extension).
  - All 17 playout tests pass (16 pass, 1 pre-existing skip).
- Updated TODO.md: Phase 1 marked complete, Phase 4 partially complete (edge cache hit/miss remains manual).
- Updated DEVELOPMENT.md: Test Fixtures marked complete, R2 Integration Test marked partially complete.

## 2026-08-09 (continued 2)

- Completed Phase 2 chat tests in `frontend/src/main.test.ts`:
  - Presence updates: join/leave system messages add and remove users from presence list, sorted rendering.
  - Private DM flow: togglePrivateDM creates correct dm: room name from sorted usernames.
  - Message rendering: system messages, self messages (message-self), and other-user messages (message-other) all render correctly.
  - Total frontend tests: 27 passing (2 test files).
- Marked Phase 4 "Document stubs/mocks" done (putObject injection pattern).
- Updated TODO.md: Phase 2 chat tests checked, Phase 4 stubs checked.
- Updated DEVELOPMENT.md: User Frontend Tests marked partially complete, R2 stubs checked.
- Updated CHANGELOG.md with Phase 2 presence/DM/message tests.

## 2026-08-09 (continued 3)

- Completed Phase 3 admin frontend tests in `frontend/src/admin.test.ts`:
  - Exported `savePlaylist` and `renderPlaylistSortable` from `admin.ts`.
  - Added playlist save test (verifies PUT /api/admin/playlist with JSON body).
  - Added playlist save error handling test (verifies failure status).
  - Added sortable rendering test (verifies index, paths, remove buttons, comment/blank line skip).
  - Total frontend tests: 31 passing (2 test files).
- Updated TODO.md: Phase 3 playlist/dashboard/API integration all checked.
- Updated DEVELOPMENT.md: Admin Frontend Tests marked partially complete.

## 2026-08-10 (continued 2)

- Implemented STREAMING.md production-readiness gaps from plan `.hermes/plans/2026-08-10_164500-production-readiness.md`:
  - **Task 1-2**: Added `runID` (ISO timestamp format) and monotonic `segSequence` for globally unique segment naming (`r-{ISOTIME}/seg-{seq}.m4s`). Replaced `strftime` pattern with run ID-based path.
  - **Task 2**: Added `watchAndPublishSegments` using `fsnotify` for real-time per-segment R2 upload (~7s delay). Previously `syncLatestToR2()` only ran after FFmpeg exit.
  - **Task 3**: Added `publishManifest` with atomic `CopyObject` (temp key → final key) to prevent manifest referencing unconfirmed segments.
  - **Task 4**: Updated `manifestCacheControl` from `"public, max-age=2"` to `"public, max-age=1, s-maxage=2, must-revalidate"` per STREAMING.md.
  - **Task 5**: Added `hls.on(Hls.Events.ERROR)` handler in `main.ts` with bounded retries (5x), exponential backoff (2s→32s), reconnecting overlay (spinner + text). Added `showReconnecting`/`hideReconnecting` functions.
  - **Task 6**: Enriched `HealthHandler` with `run_id`, `active_item`, `playlist_revision`, `last_segment_seq`, `last_r2_pub`, `consecutive_failures`. Added "unhealthy" status when R2 publish is stale (>12s).
- Files changed: `backend/playout/src/playlist.go`, `playlist_test.go`, `go.mod`, `frontend/src/main.ts`, `main.test.ts`, `style.css`, `index.html`.
- Updated `.github/instructions/TODO.md`, `BACKLOG.md`, `MEMORY.md`, `DONE.md`.
- Remaining: CORS on media.linearvoid.tv (Cloudflare R2 config, infrastructure).
  - Created `docs/operations/gitea-cloudflare.pages.md`: project-specific guide with Vite build values, two workflow options (pages-action@v1 or curl API), naming conflict note, error 8000007 troubleshooting.
  - Created `docs/operations/cloudflare-pages-setup.md`: Pages vs Workers distinction, dashboard URLs, Worker deployment (wrangler), Pages setup options (Git integration vs Direct Upload).
  - Updated `docs/SETUP.md` Cloudflare Pages section to reference the new guide.
  - Updated `docs/DEPLOYMENT.md` pipeline table to include `pages-deploy.yml` workflow.
- Created `.gitea/workflows/pages-deploy.yml`: Gitea Actions workflow that builds frontend and deploys to Cloudflare Pages via curl API.
- Updated `docs/STREAMING.md` (user edit).
- All Go vet, Go tests, and frontend tests (31) passing.
