 ## Task Management

- Plan any task in the `TODO.md` file with clear steps and mark them as completed when done. Move completed sections to DONE.md. Write entry in root `CHANGELOG.md` for any significant changes. Avoid using in-memory todo lists or update them frequently to sync from the `TODO.md` file.

Write entry in root `CHANGELOG.md` for any significant changes. Avoid using in-memory todo lists or update them frequently to sync from the `TODO.md` file.
 - Before taking any action except for planning and writing `TODO.md`, always ask user for confirmation, accept `go`, `ok`, `yes`, `next`, or `continue` to proceed. If the user says `no`, `stop`, or `cancel`, abort the action and return to planning.

+## 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`.
+- Redis restart test:
+  - 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.
+- Files changed:
+  - `.github/instructions/TODO.md`
+  - `.github/instructions/DONE.md`
+  - `frontend/src/style.css`
+  - `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).
+
+## 2026-08-10 (continued 3)
+
+- Completed Phase 2 (viewer) + Phase 3 (admin) responsive/accessibility tests:
+  - 5 viewer accessibility tests: video controls/attributes, chat panel aria-labels, chat toggle aria-expanded, message input label, reconnecting overlay aria-live/role.
+  - 3 viewer responsive tests: chat-collapsed toggle, CSS grid layout detection, now-playing aria-live.
+  - 3 admin accessibility tests: nav aria-label, active tab aria-current, nav button focusability.
+  - 2 admin responsive tests: tab content visibility, essential tab presence.
+  - Total: 45 frontend tests passing (2 test files).
+- Added coverage reporting: `vitest.config.ts` with v8 provider, thresholds at 20/15/15/20 (statements/branches/functions/lines).
+- Added `test:coverage` script to `package.json`.
+- Fixed CI: bumped Node from 20 to 22 in `ci.yml` and `pages-deploy.yml` (jsdom@30 requires Node 22+). Added `engines` to `package.json`.
+- Updated AGENTS.md: added Required tracking files table with 13 docs and update cadence.
+- All Go vet, Go tests, frontend test:coverage passing.
+- CORS on media.linearvoid.tv remains the only streaming pipeline gap (Cloudflare R2 config, not code).
+
+## 2026-08-10 (continued 4)
+
+- Verified all test suites pass after streaming pipeline implementation:
+  - Playout: `go mod tidy` (added fsnotify v1.8.0) → all tests pass
+  - Chat: 7 packages pass (go vet + go test)
+  - 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.

+- [x] Document ffmpeg fixture-generation commands in test file headers
+
+## Frontend Tests
+
+### User Frontend
+
+- [x] Video player behavior (play, pause, seek, buffering, error handling) — HLS player startup, native/fallback, URL resolution, error recovery with retries/backoff/reconnecting overlay
+- [x] Chat functionality (send/receive messages, presence, rate limiting, moderation) — send, receive, presence join/leave, DM flow, reconnect covered
+- [x] State management and data flow
+- [x] Responsive design and layout across different screen sizes — chat-collapsed toggle, CSS grid, now-playing aria

+- [x] Document test cases and expected outcomes
+- [x] Document required stubs or mocks (putObject variable injection pattern)
+
+## Streaming Pipeline
+
+- [x] **Continuous R2 sync during playout (HIGH)**: fsnotify watcher uploads segments in real-time (~7s delay)
+- [x] **Globally unique segment naming (HIGH)**: `r-{ISOTIME}/seg-{seq}.m4s` via run ID + ffmpeg monotonic sequence
+- [x] **Atomic manifest publication (MEDIUM)**: Upload to `playlist.m3u8.tmp`, then `CopyObject` to final key
+- [x] **Manifest Cache-Control alignment (LOW)**: `public, max-age=1, s-maxage=2, must-revalidate`
+- [ ] **CORS headers on HLS responses (MEDIUM)**: Needs Cloudflare R2 bucket CORS config (infrastructure, not code)
+- [x] **Player error recovery (MEDIUM)**: `hls.on(Hls.Events.ERROR)` handler with bounded retries (5x), exponential backoff, reconnecting overlay
+- [x] **Health endpoint detail (LOW)**: Added active item, run ID, playlist revision, last segment seq, last R2 pub, consecutive failures
+- [x] Source media contract + validation (H.264/AAC, 30fps, keyframe check)
+- [x] fMP4 HLS packaging (6s segments, 24 window)
+- [x] Slate fallback + recovery (`shouldEscalateToSlate`)
+- [x] R2 cache headers (immutable segments, short-lived manifest)
+- [x] Cloudflare Worker immutable `.m4s` headers
+
+## External Services
+
+> Evidence tracker: `docs/operations/cloudflare-uptimerobot-checklist.md`
+
+- [ ] UptimeRobot: add HTTP monitor for `https://linearvoid.tv/health` (5min interval)
+- [ ] UptimeRobot: add keyword monitor for `https://linearvoid.tv/hls/playlist.m3u8` (keyword: `#EXTM3U`, 5min)
+- [ ] Alert on 2 consecutive failures, notify via email + Discord/Slack webhook
+
+## Production Deployment
+
+### Host Provisioning (Hetzner — not provisioned)
+
+- [ ] Provision Hetzner CX22 (2 vCPU, 4 GB, 40 GB) in Ashburn VA, Ubuntu 24.04
+- [ ] Install Docker Engine + Compose plugin, open firewall: 80/443 (public), 2375 (runner IP only)
+- [ ] Configure Docker daemon for remote TLS access (`-H tcp://0.0.0.0:2376` with certs)
+- [ ] Create `/srv/linearvoid/data/{playlist,media,hls,chat,slate}` directories
+
+### CI/CD & Secrets
+
+- [ ] Add `CI_PROD_*` secrets to Gitea: DOCKER_HOST, R2 keys, admin password, DB password, Grafana password
+- [ ] Trigger CD workflow with `DOCKER_HOST` pointing to Hetzner IP
+
+### Smoke Test & Cutover
+
+- [ ] Verify all 11 containers start healthy, check `/health`, `/hls/playlist.m3u8`, WebSocket
+- [ ] Update Cloudflare A record `linearvoid.tv` → Hetzner IP, SSL Full (strict), test HTTPS + WSS
+- [ ] Smoke test: viewer SPA loads, HLS plays, chat connects, admin login → upload → playlist → playout
+
+### Production Operations
+
+- [ ] Set up Prometheus alerting notifications + UptimeRobot on production URL
+- [ ] Run `scripts/backup-db.sh` + `scripts/verify-backups.sh` on production host
+- [ ] Document production IP, SSH access, rollback procedure, scaling thresholds
+
+## Scaling & Performance
+
+### Load Testing
+
+- [x] Load-test scaffolding: `ws-chat.yml`, `admin-api.js`, `run-loadtests.ps1`, summarizers, README
+- [x] Cache-hit ratio exporter (`scripts/cache-hit-ratio.js` + `.ps1`)
+- [x] Saturation alerts: chat p95 latency, Redis memory usage, cache-hit ratio
+- [ ] Execute WebSocket load tests with real infrastructure — ramp 10→100→500→1000 connections, measure p95 latency + errors
+- [ ] Execute admin API benchmarks with real infrastructure — `wrk`/`k6` against `/api/admin/*`, target p95 <1s
+
+### Cache & TTFB Optimization
+
+- [ ] Optimize segment immutability and manifest TTL for cache efficiency
+- [ ] Tune manifest TTL: measure `Cf-Cache-Status` distribution, adjust to 0.5× segment duration
+- [ ] Measure playback TTFB from multiple US regions — WebPageTest from 3+ regions, target <4s warm cache
+- [ ] Track cache hit ratio and R2 ops in production — Cloudflare GraphQL → Grafana panel, alert <90%
+
+### Capacity & Future Planning
+
+- [ ] Capacity triggers: Prometheus rules for cache-miss >10%/15min, CPU >80%/10min
+- [ ] Plan Phase 2 service separation — document boundaries (playout CPU, chat latency, DB state, monitoring), estimate per-service resources
+- [ ] Plan Phase 3 multi-origin resilience — research second Hetzner location, design warm standby + DNS failover + DB/Redis replication
+
+## Feature List (Future Enhancements)
+
+- [ ] Admin backend
+  - [ ] Analytics: implement a settings entry to set matomo url and page id
+- [ ] User frontend
+  - [ ] Chat: add user registration and login flows
+  - [ ] Chat: private DM history and search
+  - [ ] Analytics: add javascript snippet to send pageview events to matomo

+- [x] Total: 78 tests across Go + frontend, all passing
+
+## Session 2026-08-07 — Runtime Validation
+
+- [x] Check `monitoring/prometheus/prometheus.yml` for completeness
+  - [x] Make sure all 7 scrape targets are included (chat, playout, nginx, redis, postgres, node, prometheus)
+  - [x] Check `monitoring/prometheus/alerts.yml` for completeness
+  - [x] Make sure configuration for prometheus is mounted into container via named volume
+- [x] Use folder `monitoring/grafana/` to create ini file for Grafana, set `GF_PATHS_CONFIG` environment variable to point to a different location than `/etc/grafana/grafana.ini` if needed
+  - [x] Set default password from `GRAFANA_PASSWORD` env var, disable user signups
+  - [x] Configure Prometheus data source in Grafana ini file
+  - [x] Include dashboards from `monitoring/grafana/dashboards/` directory to be imported into Grafana on startup
+- [x] **CD trigger parallel**: Change `cd.yml` from `workflow_run: [CI]` to `push: branches: [main]` so deploy runs in parallel with CI, not after
+- [x] **CD failure fix**: Remove `environment: production` from `cd.yml` deploy job (no Gitea environment configured, causes silent job abort after Buildx)
+- [x] **Remove redundant CI release job**: Delete `release` job from `ci.yml` — fully handled by `release.yml`
+- [x] **Tag format**: Use `*.*.*` tags (e.g. `1.0.9`) — `release.yml` pattern is `*.*.*`, not `v*.*.*`. Fix existing `v1.0.x` tags to `1.0.x`
+- [x] **Update DEPLOYMENT.md**: Document new parallel pipeline flow (push → CI + CD run simultaneously; tag push → Release builds versioned images)
+- [x] Add sections to `SETUP.md` under `## Cloudflare` for detailed instructions:

+  - [x] Tiered Cache: enable Smart Tiered Cache, validate `Cf-Cache-Status: HIT` from upper tier
+  - [x] WAF: enable OWASP Managed Ruleset, set to Simulate → review 48h → Block, enable Bot Fight Mode
+  - [x] Rate limiting: `/api/admin/login` + `/api/admin/*` → 10 req/10s per IP, Challenge action
+  - [x] HTTPS/WSS: Always Use HTTPS, HSTS max-age=31536000 includeSubDomains preload, min TLS 1.2
+  - [x] HTTPS/WSS: enforce at edge (Cloudflare) and origin (nginx), redirect HTTP → HTTPS
+  - [x] UptimeRobot: add HTTP monitor for `https://linearvoid.tv/health` (5min interval)
+  - [x] UptimeRobot: add keyword monitor for `https://linearvoid.tv/hls/playlist.m3u8` (keyword: `#EXTM3U`, 5min)

+- [x] Make sure Prometheus config is mounted into container via named volume `prometheus-config` (not bind mount)
+- [x] Make sure Prometheus alerting rules are configured and working (8 rules: ChatDown, PlayoutDown, RedisDown, etc.)
+- [x] Verify that all Prometheus targets are up and reporting metrics
+- [x] Verify that Grafana dashboards are imported and displaying metrics correctly
+- [x] Video normalization: test with MOV, MKV, variable framerate, different audio layouts
+  - Evidence: all normalized outputs probed as `h264`, `yuv420p`, `30/1`, `aac`, `48000`, `2ch`.
+- [x] Video normalization: verify output plays back-to-back in continuous concat
+  - Evidence: concat remux reported `CONCAT_OK`; output duration `25.344667s`.
+- [x] Viewer SPA: test responsive layout on iOS Safari + Android Chrome

+## CI Pipeline Optimization (Completed 2026-08-05)
+
+### Session 2026-08-06 — Batch 3: Monitoring, Security, Backups, Runbook
+
+- 4 Prometheus exporters added to compose: nginx (9113), redis (9121), postgres (9187), node (9100)
+- `monitoring/prometheus/alerts.yml`: 8 alert rules (ChatDown, PlayoutDown, RedisDown, PlayoutSlateActive, HighChatLatency, PrometheusWALFailing, HighCPU, LowDiskSpace)
+- `monitoring/prometheus/prometheus.yml`: updated with 7 scrape targets + rule_files
+- CD workflow: full Prometheus config + alerts generation inline
+- WebSocket connection rate limiting: max 5 connections per IP, 60s Redis window
+- Admin login rate limiting: max 5 attempts per IP, 5min Redis window
+- `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 from R2, temp PG container, restore + row counts
+- `docs/incident-runbook.md`: 5-tier triage (edge→origin→playout→chat→data), symptoms, mitigations, escalation
+- CI fix: removed GitHub cache from setup-go/setup-node (Gitea runner timeout), added go vet
+
+### Session 2026-08-06 — Batch 2: Admin completion, nginx polish, schedule overrides
+
+- Schedule override CRUD: `ScheduleOverride` model, `GET/POST/DELETE /api/admin/schedule/overrides`, conflict detection
+- User management actions: `POST /api/admin/users` mute/unmute/ban/unban, UI buttons per user
+- Inline moderation: mute/ban buttons on each chat log entry

+- Schedule metadata: "Now Playing" + "Up Next" overlay, public /api/schedule endpoint
+- Presence indicators: green dots in chat sidebar via join/leave tracking
+- BACKLOG.md synced with current implementation state
+
+## CI Pipeline Optimization Batch 1 (Completed 2026-08-05)
+
+- Read latest logs in `.gitea/logs/`, analyze cache config + runner setup, provide recommendations.
+- Remove `--no-cache` from `docker compose build` in test job — rebuilds all 3 images from scratch every run.
+- Remove `docker compose build` step from test job entirely — images already built in `docker` job (duplicate work).
+- Fix Go module cache — `actions/setup-go` cache always misses. Fixed: removed missing `backend/playout/go.sum` from cache-dependency-path, added `go mod download` to seed cache.
+- Fix or remove playlist validation step — `go run src/playlist.go` fails with missing `go.mod`, always falls through to `|| echo`. Removed dead step.
+- Add Docker Buildx registry cache to `docker` and `release` jobs — cache layers in Gitea registry.
+
+**Details:**
+
+- `ci.yml`: removed `docker compose build --no-cache` from test job; removed broken playlist validation step; fixed `cache-dependency-path` to only `backend/chat/go.sum`; added `go mod download` step; added `cache-from`/`cache-to` (registry type) to all 3 `docker/build-push-action` steps.
+- `release.yml`: added `cache-from`/`cache-to` (registry type) to all 3 `docker/build-push-action` steps.
+- Converted nginx build in `ci.yml` from custom shell `docker buildx build` to `docker/build-push-action@v5` for consistency and cache support.
+- Logs analyzed: `ci-test-678.log`, `ci-test-685.log`, `ci-docker-679.log`, `ci-docker-686.log`, `cd-deploy-688.log`. Key findings: npm cache works on gar v0.2.13+, Go cache misses due to missing go.sum path, docker-sans-cache rebuilds waste time, playlist validation dead code.
+
+## Color Scheme Migration (Completed 2026-08-05)
+
+New frontend color palette applied: `#32292f` (dark bg), `#b4c4ae` (light bg), `#587792` (brand), `#2ebfa5` (focus), `#04650d` (ok).
+
+- Derive full dark-theme CSS custom properties from `#32292f` base — generated `--bg-0` through `--badge-end`.
+- Derive full light-theme CSS custom properties from `#b4c4ae` base — light variants in `@media (prefers-color-scheme: light)` block.
+- Set `--brand: #587792`, `--brand-strong: #4a6780`, `--brand-contrast: #f4f8fb`.
+- Set `--focus: #2ebfa5`, `--badge-start: #2ebfa5`, `--badge-end: #1a8c78`.
+- Set `--ok: #04650d`, derived `--warn: #d49624`, `--danger: #c44a5e`.
+- Set `--ink-0/1/soft` for readable contrast on dark (`#ede8e6/#c4bdb9/#8a827e`) and light (`#1a1f18/#3a4037/#5c6358`).
+- Updated `--live-dot`, `--overlay-bg`, `--input-bg`, `--placeholder` for new tones.
+- Updated light-theme `@media (prefers-color-scheme: light)` block.
+- Replaced hardcoded admin sidebar colors (`#102a2f`, `#ecfff6`, `#ddf8ee`) with CSS custom properties.
+- Updated `.live-label` to use `var(--live-dot)` instead of hardcoded `#d62828`.
+
+**Details:**
+
+- `frontend/src/style.css`: full `:root` and light-theme `@media` block replacement with 22 color tokens from new palette.
+- Dark backgrounds shifted from `#0d1417` (teal-black) to `#32292f` (warm purple-brown); light from `#f4f6ef` to `#b4c4ae` (sage green).
+- Brand changed teal `#2ec4b6` → steel blue `#587792`; focus `#78f2e0` → teal `#2ebfa5`; success `#5add94` → forest green `#04650d`.
+- Admin sidebar `.admin-sidebar` and `.tab-trigger` hardcoded colors replaced with `var(--bg-2)`, `var(--ink-0)`, `var(--ink-1)`.
+
+## CI/CD Improvements (Completed 2026-08-05)
+
+### Build Optimization
+
+- Fix Go cache in CI: `go.sum` lives inside `backend/playout/` and `backend/chat/`, not workspace root. Update cache key pattern.
+- Add `npm run lint` script to `frontend/package.json` (was skipped via `|| true`).
+- Define missing Vite env vars (`VITE_PUBLIC_ADMIN_DEFAULT_MODERATOR`, `VITE_PUBLIC_ADMIN_DEFAULT_ROOM`, `VITE_PUBLIC_ADMIN_MODERATION_LOG_LIMIT`) or remove from HTML templates.
+
+### Deployment Hardening
+
+- Add `start_period: 30s` to chat healthcheck (needs time to connect DB + Redis).
+- Add nginx health check to CD workflow (verify `http://192.168.88.40:8080` serves frontend).
+- Add container log dump on health check failure for all services (not just playout).
+- Test `docker image prune -f` cleanup step does not remove in-use images.
+
+**Details:**
+
+- `ci.yml`: `setup-go` cache-dependency-path now lists both `backend/playout/go.sum` and `backend/chat/go.sum`
+- `package.json`: added `"lint": "tsc --noEmit"` script
+- `index.html`: removed `data-admin-default-moderator`, `data-admin-default-room`, `data-admin-moderation-log-limit` attrs (JS has fallbacks via `adminConfig`)
+- `docker-compose.prod.yml`: chat healthcheck `start_period` bumped 10s → 30s
+- `cd.yml`: health check now verifies chat (3000) + nginx (8080) + playout (8081); logs dumped per service on failure
+- `docker image prune -f --filter "until=24h"`: verified safe — Docker never removes images used by running containers
+
+## Chat Message Admin Improvements (Completed 2026-08-05)
+
+- Add `GET /api/admin/chat-log` endpoint for all chat log entries for a room, optional `?limit=` and `?before=` params. Returns JSON array.
+- Add `GET /api/admin/chat-log/:id` endpoint for single chat log entry by ID. Returns JSON object.
+- Add `DELETE /api/admin/chat-log/:id` endpoint. Returns 204 No Content.
+- Split `frontend/admin/index.html` into main template + separate files per admin page.
+- Extend `frontend/admin/chat-log.html` to display chat log entries with delete capability.
+- Confirmation dialog before deleting chat log entry.
+- Pagination in chat log list.
+- Search/filter in chat log list.
+- Add `DELETE /api/admin/chat-log/bulk` endpoint for bulk deletion with checkbox select-all UI.
+
+**Details:**
+
+- Backend: `handleAdminChatLog`, `handleAdminChatLogByID`, `handleAdminChatLogBulk` in `main.go`
+- Types: `ChatLogEntry`, `ChatLogListResponse`, `ChatLogBulkDeleteRequest`
+- Frontend: 9 page HTML files + dynamic `index.html` template with `loadPageContent` / `switchTab` / `bindPageEvents`
+- `admin.ts`: `refreshChatLog`, `deleteChatEntry`, `bulkDeleteChatLog`, pagination (prev/next), filter (room/username/text), `chatLogState` management
+
+## Security Improvements (Completed 2026-08-05)
+
+- Added catch-all `/` route to backend router returning JSON 404 for unhandled requests.
+- Verified all admin API + frontend admin endpoints require auth: Go `requireAdminAuth` middleware guards `/api/admin/*` (except login/logout/session), nginx `auth_request /_admin_auth` guards `/admin/` frontend routes. No gaps.
+
+## Documentation Polish (Completed 2026-08-04)
+
+### Architecture Documentation (docs/architecture/README.md) Updates
+
+- Add monitoring and alerting details (Prometheus rules, Grafana dashboards).
+- Add security considerations section (auth, rate limiting, WAF).
+- Add performance benchmarks / capacity planning section.
+- Add disaster recovery / backup procedures.
+- Add scaling strategy documentation.
+- Add API documentation section (chat WebSocket, playout REST, admin REST).
+- Add video normalization specification details.
+- Add Cloudflare configuration reference.
+
+### Additional Documentation Files
+
+- Create API.md with WebSocket and REST API specifications.
+- Create DEPLOYMENT.md with production deployment guide.
+- Create MONITORING.md with Prometheus/Grafana setup guide.
+- Create SECURITY.md with security considerations and best practices.
+- Keep `CHANGELOG.md` aligned with documentation and release changes.
+
+## Frontend CSS and JS Rewrite (No Tailwind) (Completed 2026-08-04)
+
+### Remove Tailwind and Replace with Native CSS/JS
+
+- Removed Tailwind from frontend dependencies and build pipeline (`package.json`, PostCSS/Tailwind config, CSS directives).
+- Removed Tailwind CDN usage from admin HTML pages and template references.
+- Replaced utility-class styling with custom CSS architecture using design tokens.
+- Organized styles into clear sections for viewer, admin, and shared layout.
+- Responsive behavior for mobile, tablet, desktop breakpoints.
+- Replaced Tailwind-dependent interaction patterns with plain JavaScript.
+- Kept and improved UI behavior in navigation, forms, tables, status messaging.
+
+### Accessibility (Latest Guidelines)
+
+- Applied WCAG 2.2 AA baseline across rewritten UI.
+- Semantic structure and landmarks (`header`, `nav`, `main`, `section`, proper heading order).
+- Full keyboard operability for controls, tab views, interaction flows.
+- Visible focus indicators with sufficient contrast and logical tab sequence.
+- Text/background and component contrast meets AA thresholds.
+- Accessible labels, helper text, error messaging for form controls.
+- Validated ARIA usage for dynamic states only where native semantics insufficient.
+- Respected reduced-motion preferences.
+
+### Validation and Documentation
+
+- Ran frontend production build, resolved all Tailwind/PostCSS directive warnings.
+- Local preview smoke checks for viewer chat send, admin tab navigation, admin login states.
+- Manually tested key user flows in admin and viewer pages after rewrite.
+- Updated `CHANGELOG.md` with rewrite summary.
+
+### Dark Mode First
+
+- Dark-mode-first design with CSS custom properties and light-scheme override path.
+
+### Player Page Layout
+
+- Refactored viewer to single header with logo/title/subtitle and chat toggle.
+- Consolidated viewer into one main content area: responsive video/chat split on desktop, stacked on mobile.
+- Viewer uses full viewport dimensions, removed desktop outer scrollbars.
+- Video player visible and responsive with viewport changes.
+- Removed legacy "Now Playing" UI controls and related runtime update behavior.
+
+## Admin UI Features (Completed 2026-08-04)
+
+### Media Library - Full CRUD
+
+- Documentation: ADR-006 revised to implemented Postgres-first storage and media model decisions.
+- Planning: TODO and CHANGELOG aligned with implementation progress.
+- Backend: Media GORM model and AutoMigrate added.
+- Backend: `ffprobe` duration extraction on upload, persisted duration metadata.
+- Backend: full CRUD for `/api/admin/media` with GET/POST and GET/PUT/DELETE by id.
+- Backend: schedule and dashboard endpoints extended with media duration totals and counts.
+- Frontend: admin media library updated with runtime display and edit/delete/upload controls.
+- Frontend: runtime display added to Schedule and Dashboard (total and per-item runtime).
+
+### Schedule Page - Video Runtime Display
+
+- Implemented after backend duration support.
+
+### Dashboard - Total Video Runtime
+
+- Implemented after backend stats support.
+
+### Implementation Notes Applied
+
+- Used existing GORM + Postgres setup.
+- Installed `ffmpeg` in chat Dockerfile, used `ffprobe` via `exec.Command`.
+- Media metadata stored in same DB as messages/moderation; media binaries remain on filesystem.
+- Admin endpoints protected with `requireAdminAuth` middleware.
+- Media listing uses DB-backed records.
+- Added `formatDuration(seconds int) string` helper for HH:MM:SS formatting.
+
+## Upload functionality
+
+- Large file uploads chunked and resumable, with progress feedback.
+- Uploads up to 2GB with server-side validation of file type and size.
+
+## Documentation Polish - Architecture README (Partial, Completed Items)
+
+- Updated Deployment View with CI/CD pipeline architecture and Mermaid diagram.
+
+## Release Validation (Completed 2026-08-04)
+
+### Release Workflow
+
+- Reviewed `.gitea/workflows/release.yml` — triggers on `v*` tags + `workflow_dispatch`, builds all 3 images.
+- Fixed Nginx build context: `dockerfile:` → `file:` in `release.yml`.
+- Replaced `softprops/action-gh-release@v1` (GitHub-only) with `curl` → Gitea API `POST /repos/{owner}/{repo}/releases`.
+- Added VERSION empty-guard to `release.yml` — fails gracefully with error message.
+- Confirmed curl API working: `POST /repos/zwitschi/linearvoid/releases` returns 201, release at `https://git.allucanget.biz/zwitschi/linearvoid/releases/tag/1.0.3`.
+- Semver tags verified: `type=semver,pattern={{version}}`, `type=semver,pattern={{major}}.{{minor}}`, `type=raw,value=latest`.
+
+### Dependency Update Workflow
+
+- Replaced `peter-evans/create-pull-request@v5` (GitHub-only) with Gitea API `POST /repos/{owner}/{repo}/pulls` via `curl`.
+- Added `git commit` + `git push origin HEAD:dependency-updates --force` step before PR creation.
+- Handles HTTP 201 (new PR) and 409 (PR exists, force-push updated commits).
+
+## Documentation Polish — Root README.md (Completed 2026-08-04)
+
+- Consolidated badges: build status, license, version, release notes.
+- Quick start section with `docker compose up --build` and viewer/admin/metrics URLs.
+- Inline Mermaid architecture diagram.
+- Troubleshooting table + environment variables reference table.
+- API endpoint reference table (Chat, Playout, Nginx).
+- Contributing summary with links to `CONTRIBUTING.md` and `LICENSE`.
+
+## Fix CI Docker Build Failures (Completed 2026-08-04)
+
+- **Root Cause**: CI `docker` job used `context: .` (repo root) for Playout build, but Dockerfile COPY paths relative to `backend/playout/`. Changed `context: .` → `context: ./backend/playout` in `.gitea/workflows/ci.yml`.
+- Verified Chat image context (`./backend/chat`) correct.
+- Verified Nginx image context (`.`) correct (uses `frontend/` and `infrastructure/nginx/` from root).
+- Build cache resolved automatically with fresh push after context fix.
+
+## Metrics Endpoint (Completed)
+
+- Added `/metrics` to chat backend with Prometheus exposition: connected clients, stored messages, moderation actions, Redis state, active admin sessions, build info.
+- Exposed `/metrics` through nginx for browser and domain access.
+- Updated Prometheus scrape config to target implemented metrics endpoints only.
+- Replaced placeholder Grafana dashboard queries with live chat metrics and scrape-health panels.
+- Validated metrics access: `http://localhost/metrics`, `https://linearvoid.tv/metrics`, Prometheus target discovery, inside Prometheus container.
+
+## Admin Panel (Completed)
+
+- Replaced static admin mock data with real API-backed data loading.
+- Added backend admin endpoints for playlist read/write, moderation actions, audit-log queries, analytics, system-health summaries, users, schedule, media management.
+- Wired admin UI forms and tabs to backend endpoints.
+- Session-based admin auth for `/admin/` and `/api/admin/*`, including login/logout flows.
+- Moved admin panel config to `.env` variables, documented required auth settings.
+
+## Local Docker Validation (Completed)
+
+- `docker compose build` passes for `nginx`, `chat`, `playout`.
+- `docker compose up --build -d` starts all services cleanly, playout healthy, nginx serving built frontend.
+- Fixed local compose-network runtime defaults: `REDIS_URL=redis://redis:6379/0`, `DATABASE_URL=postgres://linearvoid:linearvoid@db:5432/linearvoid?sslmode=disable` work inside containers.
+- Chat honors `DATABASE_URL`, supports SQLite and Postgres, validated against compose Postgres service.
+- Local sample media and mounted playlists generate HLS output correctly.
+- Fixed concat-playlist parsing: playout validation no longer passes literal `file '...'` entries to `ffprobe`.
+- Fixed HLS segment naming: fresh local output uses timestamped immutable segment names.
+- Admin production build emits `dist/admin/index.html`, nginx serves `/admin/` as own entrypoint, stale hashed assets return `404` instead of HTML fallback.
+- Restored nginx MIME mappings: built JS/CSS assets served with browser-safe content types.
+
+Notes:
+
+- Preferred local access: `https://linearvoid.tv` and `https://linearvoid.tv/admin` through Cloudflare and Nginx Proxy Manager.
+- Direct `localhost` access is fallback when public proxy path intentionally bypassed.
+
+## Base URL Rollout: linearvoid.tv (Completed)
+
+- Production URL model: app, admin, WebSocket on `https://linearvoid.tv`; HLS on dedicated `MEDIA_DOMAIN`, target `https://media.linearvoid.tv`.
+- Introduced explicit public URL env vars for viewer, WebSocket, media endpoints; localhost-friendly defaults preserved for dev.
+- Refactored frontend to stop hardcoding `localhost` URLs, use same-origin or env-driven endpoint resolution.
+- Updated nginx config: host handling, SPA routing, `/ws`, `/hls/` match `linearvoid.tv` deployment model.
+- Updated `.env.example`, `SETUP.md`, deployment docs with final DNS, Cloudflare, TLS, runtime values.
+- Validated localhost dev and production domain behavior via frontend production builds using local and production public URL variables.
+
+Notes:
+
+- Viewer SPA, admin UI, chat WebSocket use same origin on `linearvoid.tv`.
+- Media delivery split from app origin for Cloudflare R2 + cache-rule alignment; production target `media.linearvoid.tv` via `MEDIA_DOMAIN`.
+- Local dev keeps localhost defaults; production swaps only public hostnames, not internal compose service names.
+- Public frontend URL vars in root `.env` / `.env.example`: `VITE_PUBLIC_APP_URL`, `VITE_PUBLIC_WS_URL`, `VITE_PUBLIC_HLS_URL`; Vite reads from repo root through `frontend/vite.config.ts`.
+- Frontend resolves WebSocket and HLS from Vite env first, falls back to same-origin `/ws` and `/hls/playlist.m3u8`.
+- Nginx treats `linearvoid.tv` as canonical app host, redirects `www.linearvoid.tv`, proxies `/ws` with forwarded headers, keeps `/hls/` as local fallback.
+
+## Task List Maintenance - 2026-08-03
+
+- Moved completed TODO items out of active queue.
+- Updated architecture docs table of contents to include ADR-001 through ADR-007.
+- Added ADR-002 through ADR-007 to architecture decisions section.
+- Updated `SETUP.md` with latest docker-compose and environment guidance.
+- Consolidated redundant active TODO items, reprioritized remaining work around `linearvoid.tv` rollout, release validation, documentation polish.

+
+## CI/CD Pipeline — Full Deployment (Completed 2026-08-04)
+
+### CI Pipeline
+
+- CI workflow on Gitea Actions runner — **passed** (task 569).
+- `npm ci` — 38 packages, 0 vulnerabilities.
+- `npm run build` — all outputs built (index.html, admin pages, assets).
+- `docker compose build --no-cache` — all 3 images (playout, chat, nginx) built.
+- Multi-stage nginx Dockerfile (frontend baked in).
+- Removed frontend-only image from CI & release workflows.
+- All images pushed to Gitea registry.
+
+### CD Pipeline — Registry Login Fixed
+
+- Renamed all `GITEA_*` → `CI_*` vars in `.env`, `.env.example`, `docker-compose.yml`, all workflows, `SETUP.md`, `DONE.md`.
+- New secrets `CI_REGISTRY_USER` and `CI_REGISTRY_TOKEN` created in Gitea.
+- Old `GITEA_USERNAME` and `GITEA_TOKEN` removed.
+- **Login confirmed** — `cd-deploy-568.log` shows `Login Succeeded!` using new `CI_*` secrets.
+
+### CD Pipeline — Push Images to Registry — FIXED ✅
+
+- Added `Prepare environment` step to `cd.yml`: generates minimal `.env` inline.
+- Configured `DOCKER_HOST: tcp://192.168.88.40:2375` in `cd.yml` — directs deploy/cleanup to test server at `192.168.88.40`.
+- Updated health check to query `http://192.168.88.40` instead of `localhost`.
+- CD login works + images pull.
+- Added `.env` creation step to CD workflow.
+- Documented Gitea Actions secrets setup in `SETUP.md`.
+- Added secrets protection guidelines to `AGENTS.md`.
+- **Fixed Prometheus mount failure**: switched to named volume `prometheus-config` + CD seeds config at deploy time.
+- **Fixed playout crash-loop**: changed playlist volume from `:ro` to `:rw` so startup script can create demo playlist.
+- **Fixed chat unhealthy status**: added `curl` to chat runtime Alpine image for healthcheck.
+- **CD triggers after CI success**: changed CD trigger from `push` to `workflow_run` on CI completion.
+- **Images built before deployment**: CI builds and pushes images, CD pulls and deploys.
+- Containers start and pass health checks on `192.168.88.40`.
+- `docker push git.allucanget.biz/zwitschi/linearvoid/playout:latest`
+- `docker push git.allucanget.biz/zwitschi/linearvoid/chat:latest`
+- `docker push git.allucanget.biz/zwitschi/linearvoid/nginx:latest` — **rebuilt with multi-stage Dockerfile, frontend bundled** ✅
+
+### CD Pipeline — Track C: Run CD Workflow
+
+- Images pulled on runner ✅.
+- `.env` fix applied — `cd.yml` creates inline config before deploy.
+- Health checks pass after containers start.
+- `docker image prune -f` cleanup does not remove in-use images.
+
+### Local Test Environment Deployment (Remote Docker Host)
+
+- **Configure Alpine Docker Host** (`192.168.88.40`) to listen on TCP `2375`:
+  - Edit `/etc/conf.d/docker`, set `DOCKER_OPTS="-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375"`.
+  - Restart Docker: `rc-service docker restart`.
+  - Verify: `netstat -tlnp | grep 2375`.
+- **Configure local env** to point to remote Docker host at `192.168.88.40:2375` via `DOCKER_HOST`.
+- **Verify connection**: `docker info` confirms communication with remote host.
+- **Test remote build and deploy** from source: `docker compose up -d --build` — **succeeded after removing prometheus/grafana from gitignore** ✅.
+- **Test remote production-like deploy** from Gitea registry: `docker compose -f docker-compose.prod.yml pull && docker compose -f docker-compose.prod.yml up -d`.
+- **Verify remote health checks**:
+  - Playout: `http://192.168.88.40:8081/health`
+  - Chat: `http://192.168.88.40:3000/health`
+  - Nginx: `http://192.168.88.40:8080`
+- **Reset local env** by clearing `DOCKER_HOST`.
+
+### CI Docker Job (push to registry)
+
+- CI `docker` job triggers after `test` passes on `main` push.
+- CI pushes `playout`, `chat`, `nginx` images to Gitea Container Registry.
+- Metadata tagging validated (branch-based + `latest`).
+
+### Workflow Fixes & Adjustments
+
+- **Fix `.env` heredoc indentation in `cd.yml`**: Removed leading spaces inside heredoc so Docker Compose parses correctly.
+- **Remove `type=gha` cache from `ci.yml`**: Gitea Actions doesn't support GitHub Actions cache (`type=gha`). Removed.
+- **Verify health check endpoints in `cd.yml`**: Confirmed `curl` targets match actual ports (`chat:3000`, `playout:8081`).
+- **Fix nginx build in CI**: Switched from `docker/build-push-action` (ignored `dockerfile` param) to shell-based `docker buildx build --file`.
+
+### CI/CD Pipeline Architecture Documentation
+
+- Added CI/CD Pipeline Architecture section to `docs/architecture/README.md` with Mermaid diagram.
+- Documented pipeline sequence: CI builds/pushes → CD pulls/deploy.
+- Updated Deployment View with docker-compose services and remote host details.
+
+## Gitea Self-Hosting Migration (Completed)
+
+### Gitea Instance Setup & Repository Migration
+
+- Verified Gitea instance at <https://git.allucanget.biz> accessible and configured — Gitea 1.27.1
+- Created org/user `zwitschi` on Gitea

+  - Replaced `actions/setup-node@v4` with Gitea-compatible install
+  - Updated Docker image references to Gitea Container Registry
+  - Configured registry auth for Gitea Container Registry
+  - Added Gitea-specific env vars (CI_SERVER_URL, CI_REGISTRY_TOKEN)
+- Created separate workflows for CI, CD, Release, Dependency updates
+
+### Gitea Container Registry Setup
+
+- Enabled Container Registry in Gitea config (app.ini)
+- Configured storage backend
+- Set up registry auth (token-based, OAuth2)
+- Image naming convention: `git.allucanget.biz/zwitschi/linearvoid/<service>:<tag>`

+## Session 2026-08-10 — STREAMING.md Production Readiness
+
+Completed 6 of 7 streaming pipeline gaps from STREAMING.md contract audit:
+
+- [x] **Continuous R2 sync (HIGH)** — Added `watchAndPublishSegments()` using `fsnotify` to upload segments in real-time (~7s delay), replacing batch-on-exit pattern.
+- [x] **Globally unique segment naming (HIGH)** — Added `initRunID()` generating `r-ISOTIME` IDs and `seg-{seq}.m4s` monotonic naming. Replaced `strftime` collision-prone pattern.
+- [x] **Atomic manifest publication (MEDIUM)** — Added `publishManifest()` uploading to `playlist.m3u8.tmp` then `CopyObject` to final key.
+- [x] **Manifest Cache-Control contract (LOW)** — Updated to `public, max-age=1, s-maxage=2, must-revalidate`.
+- [x] **Player error recovery (MEDIUM)** — Added `hls.on(ERROR)` handler with bounded retries (5x), exponential backoff (2s→32s), reconnecting overlay with spinner.
+- [x] **Health endpoint detail (LOW)** — Enriched `/health` with `run_id`, `active_item`, `playlist_revision`, `last_segment_seq`, `last_r2_pub`, `consecutive_failures`, and `unhealthy` detection.
+- [ ] CORS on `media.linearvoid.tv` — Remaining infrastructure-only (Cloudflare R2 CORS configuration, not code).
+
+**Files changed:** `backend/playout/src/playlist.go` (+171/-35), `playlist_test.go` (+51/-7), `go.mod` (+2), `frontend/src/main.ts` (+76/-2), `main.test.ts` (+43/-1), `style.css` (+37), `index.html` (+5).
+**Tests:** HealthHandler tests updated for new fields + added Unhealthy test. Player error recovery test added. All existing tests preserved.
+
+## Session 2026-08-10 — Phase 2+3 Frontend Coverage
+
+Completed Phase 2 (viewer) and Phase 3 (admin) responsive/accessibility tests + coverage:
+
+- [x] **Viewer accessibility (5 tests):** video controls/autoplay/playsinline attributes, chat panel aria-labels (live region + panel label), chat toggle aria-expanded state, message input label association, reconnecting overlay aria-live=assertive + role=alert.
+- [x] **Viewer responsive (3 tests):** chat-collapsed CSS class toggle, viewer-content CSS grid display, now-playing aria-live=polite.
+- [x] **Admin accessibility (3 tests):** nav aria-label, active tab aria-current=page, nav button focusability (no tabindex/disabled).
+- [x] **Admin responsive (2 tests):** tab content visibility (display not none), essential tab presence.
+- [x] **Coverage enforcement:** Added vitest config with v8 provider, 40% statements/lines + 30% branches/functions thresholds. Added `test:coverage` script and CI step.
+
+**Files:** `frontend/src/main.test.ts` (+65), `frontend/src/admin.test.ts` (+55), `frontend/vitest.config.ts` (+12), `frontend/package.json` (+1), `.gitea/workflows/ci.yml` (+3).

+## [Unreleased]
+
+## [1.0.12] - 2026-08-11
+
+### Changed
+
+- **Task tracking consolidated**: Removed `DEVELOPMENT.md` and moved all development tasks to `.github/instructions/BACKLOG.md` as the single source of truth. `TODO.md` updated to reference `BACKLOG.md` and `DONE.md`.
+
+### Fixed
+
+- **Playout R2 endpoint validation**: `initR2Client()` now validates all required R2 environment variables (`R2_ENDPOINT`, `R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, `R2_BUCKET_NAME`) before creating the S3 client. Previously, an empty `R2_ENDPOINT` caused cryptic `Custom endpoint '' was not a valid URI` errors on every segment upload attempt. Playout now gracefully degrades when R2 is not configured — local HLS via nginx continues to work.
+- **CD workflow missing R2 secrets**: `.gitea/workflows/cd.yml` "Prepare environment" step now injects all R2_ variables (`R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, `R2_BUCKET_NAME`, `R2_ENDPOINT`, plus admin variants) from Gitea secrets. Previously the generated `.env` was missing R2 entirely, causing the playout container to start with an empty endpoint.
+- **Deployment docs**: `docs/DEPLOYMENT.md` now includes explicit R2 and Cloudflare variable lists plus a "Gitea Secrets" table documenting all 15 required secrets.

-### Folder Explanations
+### Documentation

- **`frontend/`**: The viewer experience — minimal, modern SPA with Tailwind + Alpine.js (or vanilla). Uses `hls.js` for playback and a WebSocket client for chat.
- **`backend/playout/`**: Core linear engine. FFmpeg consumes a normalized playlist and outputs continuous HLS. Includes normalization validation.
- **`backend/chat/`**: Independent WebSocket service (Node.js/Socket.io or Go). Handles public rooms, private DMs, presence (Redis), persistence (PostgreSQL/SQLite), rate limiting, and moderation.
- **`backend/shared/`**: Reusable code (types, utils, video validation).
- **`infrastructure/`**: Everything needed to deploy and configure the stack (Docker, Nginx, Cloudflare rules, future Terraform).
- **`scripts/`**: One-off and CI-friendly scripts for video preparation, R2 sync, backups, and playlist management.
- **`monitoring/`**: Grafana dashboards, Prometheus rules, logging configuration.
- **`docs/architecture/`**: Complete arc42 documentation + ADRs 001-007 (the single source of truth for all architectural decisions).
+- `docs/`: Folder containing all documentation for the project, including architecture, ADRs, operational procedures, and setup guides.
+- `docs/architecture/`: Architecture documentation, including high-level system architecture, component interactions, and decision records (ADRs).

+### Infrastructure
+
+Everything needed to deploy and configure the stack (Docker, Nginx, Cloudflare rules, future Terraform).
+
+- Cloudflare
+  - [worker.js](infrastructure/cloudflare/worker.js) — adds immutable cache headers to HLS segments
+- Nginx
+  - [Dockerfile](infrastructure/nginx/Dockerfile) — builds Nginx with custom config
+  - [nginx.conf](infrastructure/nginx/nginx.conf) — reverse proxy, static SPA, HLS delivery
+
+### Monitoring
+
+Grafana dashboards, Prometheus rules, logging configuration.
+
+- Grafana
+  - dashboards
+    - [dashboard.json](monitoring//grafana/dashboards/dashboard.json) — operational dashboards for playout, chat, and Redis
+    - [dashboard.yml](monitoring//grafana/dashboards/dashboard.yml) — operational dashboards for playout, chat, and Redis
+  - datasources
+    - [datasource.yml](monitoring/grafana/datasources/datasource.yml) — Prometheus datasource configuration
+  - [dashboard.json](monitoring/grafana/dashboard.json) — operational dashboards for playout, chat, and Redis
+- Prometheus
+  - [alerts.yml](monitoring/prometheus/alerts.yml) — alerting rules for playout, chat, Redis, and system health
+  - [prometheus.yml](monitoring/prometheus/prometheus.yml) — scrape targets for playout, chat, Redis, and system metrics
+
+### Scripts
+
+One-off and CI-friendly scripts for video preparation, R2 sync, backups, and playlist management.
+
+- loadtest/
+  - [admin-api.js](scripts/loadtest/admin-api.js) — admin API load test script
+  - [run-loadtests.ps1](scripts/loadtest/run-loadtests.ps1) — PowerShell script to run load tests
+  - [summarize-artillery.ps1](scripts/loadtest/summarize-artillery.ps1) — PowerShell script to summarize Artillery load test results
+  - [summarize-k6.ps1](scripts/loadtest/summarize-k6.ps1) — PowerShell script to summarize k6 load test results
+  - [ws-chat.yml](scripts/loadtest/ws-chat.yml) — WebSocket chat load test configuration

- [ ] Set up Prometheus alerting notifications + UptimeRobot on production URL
- [ ] Run `scripts/backup-db.sh` + `scripts/verify-backups.sh` on production host
- [ ] Document production IP, SSH access, rollback procedure, scaling thresholds
-
-## Scaling & Performance (planning only)
-
- [ ] Tune manifest TTL: measure `Cf-Cache-Status` distribution, adjust to 0.5× segment duration
- [ ] Measure TTFB: WebPageTest from 3+ US regions, target <4s warm cache, document baseline
- [ ] Load-test WebSocket: `artillery` or Go script, ramp 10→100→500→1000 connections, measure p95 latency + errors (scaffolding complete; benchmark execution pending)
- [ ] Benchmark admin API: `wrk`/`k6` against `/api/admin/*`, target p95 <1s, identify slow queries (scaffolding complete; benchmark execution pending)
- [ ] Track cache hit ratio: Cloudflare GraphQL → Grafana panel, alert <90%
- [ ] Capacity triggers: Prometheus rules for cache-miss >10%/15min, chat p95 >1s/5min, CPU >80%/10min, Redis memory >85%/10min

+# Prometheus scrape target metric names
+
+Here are ready‑to‑run **cURL** commands you can use to query each Prometheus scrape target and list the metric names they expose.  
+The Prometheus HTTP API endpoint `http://localhost:9090/api/v1/label/__name__/values` returns all metric names currently known for the target’s job/instance.
+
+---
+
+## 1. Chat (`http://chat:3000/metrics`)
+
+```bash
+curl -s 'http://localhost:9090/api/v1/label/__name__/values?match[]={job="chat",instance="chat:3000"}' | jq .

+
+```bash
+curl -s 'http://localhost:9090/api/v1/label/__name__/values?match[]={job="playout",instance="playout:8081"}' | jq .
+```

+## 5. Postgres exporter (`http://postgres-exporter:9187/metrics`)
+
+```bash
+curl -s 'http://localhost:9090/api/v1/label/__name__/values?match[]={job="postgres",instance="postgres-exporter:9187"}' | jq .
+```
+
+## 6. Prometheus itself (`http://prometheus:9090/metrics`)

+
+```bash
+curl -s 'http://localhost:9090/api/v1/label/__name__/values?match[]={job="redis",instance="redis-exporter:9121"}' | jq .
+```
+
+---
+
+### How it works
+
+- `http://localhost:9090` – address of your Prometheus server.
+- `/api/v1/label/__name__/values` – API call that lists _all_ metric names (`__name__` label) known to Prometheus.
+- `match[]` – a selector that restricts the result to the specific `job` and `instance` you care about.
+- `-s` – silent mode (no progress meter).
+- `| jq .` – pretty‑prints the JSON response (optional but handy).
+
+Running any of these commands will output a JSON array like:
+
+```json
+[
+  "up",
+  "process_cpu_seconds_total",
+  "http_requests_total",
+  ...
+]
+```
+
+which is the full set of metrics currently being scraped from that target. Adjust the Prometheus host/port if it differs from `http://localhost:9090`.

+# Prometheus scrape target metric names (Windows)
+
+Below are **cURL** one‑liners you can run from a Windows command prompt (or PowerShell) that query the Prometheus HTTP API and print the raw JSON list of metric names for each target.  
+Since **jq** isn’t installed, the commands simply echo the JSON response; you can pipe it to `findstr` or PowerShell’s `ConvertFrom‑Json` if you want a prettier view.

+
+### Making the output a bit more readable (optional)
+
+If you have **PowerShell** (available on Windows 10/11), you can format the JSON nicely:
+
+```powershell
+curl "http://localhost:9090/api/v1/label/__name__/values?match[]={job=`"chat`",instance=`"chat:3000`"}" |
+  ConvertFrom-Json |
+  Select-Object -ExpandProperty data |
+  Sort-Object
+```
+
+Replace the URL part with the one for the target you’re interested in. The pipeline:
+
+1. Calls `curl` (the built‑in alias for `Invoke-WebRequest` in PowerShell).
+2. `ConvertFrom-Json` parses the JSON.
+3. `Select-Object -ExpandProperty data` extracts the array of metric names.
+4. `Sort-Object` alphabetizes them.
+
+You can similarly pipe the output to `findstr /i "http_requests_total"` to search for a particular metric name without any extra tools.

+| ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
+| **Prometheus address**  | If your Prometheus container isn’t bound to `localhost:9090`, replace `localhost:9090` with the appropriate host/port (e.g., `127.0.0.1:9090`). |
+| **Target job/instance** | The `job` and `instance` values must match the labels shown in your UI (they’re case‑sensitive).                                                |
+| **PowerShell vs CMD**   | The raw `curl` commands work in both CMD and PowerShell; the PowerShell‑only pretty‑print uses `ConvertFrom‑Json`.                              |

+# Gitea to Cloudflare Pages — Linear Void
+
+## Goal
+
+Deploy the Linear Void frontend (Vite + TypeScript SPA) from Gitea to Cloudflare Pages using Gitea Actions.
+
+## Prerequisites
+
+> **Important:** The Pages project must exist before the API deploy call works. You'll get error 8000007 ("Project not found") if you skip this step.
+
+1. **Cloudflare Pages project** created first:
+   - Dashboard → Workers & Pages → Create → Pages → Direct Upload
+   - Name it `linearvoid` (or a different name if `linearvoid` is already taken by a Worker — see note below)
+   - See [Cloudflare Pages Setup](./cloudflare-pages-setup.md) for full details.
+2. **Project name**: note the exact name (e.g., `linearvoid`).
+3. **API token** with Pages permissions:
+   - Create at <https://dash.cloudflare.com/profile/api-tokens>
+   - Permission: `Account → Cloudflare Pages → Edit`
+   - Store in Gitea → Settings → Secrets as `CLOUDFLARE_API_TOKEN`
+4. **Account ID** from Cloudflare dashboard overview → store as `CLOUDFLARE_ACCOUNT_ID`
+
+> **Naming conflict:** If a Worker already exists with the name `linearvoid`, the Pages project must use a different name (e.g., `linearvoid-site`). Update the `projectName` in the workflow accordingly. Workers and Pages share a namespace under "Workers & Pages".
+
+## Project-specific values
+
+| Setting            | Value                                                      |
+| ------------------ | ---------------------------------------------------------- |
+| Framework          | Vite + TypeScript                                          |
+| Build command      | `cd frontend && npm install && npm run build`              |
+| Output directory   | `frontend/dist`                                            |
+| Node version       | 20                                                         |
+| Multi-page entries | `index.html`, `admin/index.html`, `admin/login/index.html` |
+
+## Gitea Actions workflow
+
+Create `.gitea/workflows/pages-deploy.yml`:
+
+```yaml
+name: Deploy to Cloudflare Pages
+
+on:
+  push:
+    branches: ["main"]
+  workflow_dispatch: {}

+    steps:
+      - name: Checkout
+        uses: actions/checkout@v4
+
+      - name: Setup Node
+        uses: actions/setup-node@v4
+        with:
+          node-version: 22
+
+      - name: Install dependencies
+        run: cd frontend && npm ci
+
+      - name: Build
+        run: cd frontend && npm run build
+
+      - name: Deploy to Cloudflare Pages
+        uses: cloudflare/pages-action@v1
+        with:
+          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
+          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
+          projectName: linearvoid
+          directory: frontend/dist
+          gitHubToken: ${{ secrets.GITEA_TOKEN }}
+```
+
+If the `cloudflare/pages-action@v1` action is unavailable from Gitea, use the direct Cloudflare Pages API (multipart/form-data with manifest):
+
+Snippet to generate a manifest in format `-F manifest='{"index.html": "abc123", "style.css": "def456"}'`
+
+```bash
+# Build manifest form argument from all files in frontend/dist
+form_args="-F manifest={"
+for file in $(find frontend/dist -type f | sed 's|^frontend/dist/||'); do
+  hash=$(sha256sum "frontend/dist/$file" | awk '{print $1}')
+  form_args="$form_args\"$file\":\"$hash\","
+done
+form_args="${form_args%,}}" # remove trailing comma and close JSON
+```
+
+```yaml
+- name: Generate deployment manifest
+  run: |
+    cd frontend/dist
+    form_args="-F manifest={"
+    for file in $(find . -type f ! -name manifest.json | sed 's|^\./||'); do
+      hash=$(sha256sum "$file" | awk '{print $1}')
+      form_args="$form_args\"$file\":\"$hash\","
+    done
+    form_args="${form_args%,}}" # remove trailing comma and close JSON
+    echo "Form arguments: $form_args"
+    echo "FORM_ARGS=$form_args" >> $GITHUB_ENV
+
+- name: Deploy to Cloudflare Pages
+  env:
+    CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
+    CLOUDFLARE_ACCOUNT_ID: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
+  run: |
+    cd frontend/dist
+    form_args="$FORM_ARGS" # use form arguments generated in previous step
+    COMMIT_HASH=$(git rev-parse --short HEAD 2>/dev/null || echo "unknown")
+    curl -sS -X POST \
+      "https://api.cloudflare.com/client/v4/accounts/${CLOUDFLARE_ACCOUNT_ID}/pages/projects/linearvoid/deployments" \
+      -H "Authorization: Bearer ${CLOUDFLARE_API_TOKEN}" \
+      -F "commit_hash=${COMMIT_HASH}" \
+      $form_args
+```
+
+This matches the Cloudflare Pages Direct Upload API: `Content-Type: multipart/form-data`, each file as a separate form field, and a `manifest` JSON mapping filenames to SHA-256 hashes.
+
+## Secrets to add in Gitea
+
+| Secret                  | Value                                |
+| ----------------------- | ------------------------------------ |
+| `CLOUDFLARE_API_TOKEN`  | API token with Pages:Edit permission |
+| `CLOUDFLARE_ACCOUNT_ID` | Cloudflare account ID from dashboard |
+
+## Verify deployment
+
+1. Push to `main` or trigger manually from Gitea Actions.
+2. Check **Gitea Actions** → job logs for the deploy step.
+3. Check **Cloudflare Pages** → Deployments for the new deployment.
+4. Visit the `.pages.dev` preview URL, then promote to `linearvoid.tv` when ready.
+
+## Notes
+
+- The existing `ci.yml` already builds the frontend; the Pages deploy workflow is additive and independent.
+- Multi-page SPA (`vite.config.ts`) produces three entry points — Cloudflare Pages serves them correctly.
+- For SPA fallback routing, add a `frontend/public/_redirects` file with `/* /index.html 200` before building.
+- If deployments fail with 403, verify the API token has `Account → Cloudflare Pages → Edit` permission.
+- If you get error **8000007** ("Project not found"), the Pages project hasn't been created yet. Create it via the Cloudflare dashboard (Workers & Pages → Create → Pages → Direct Upload) first, then re-run.
+- If `linearvoid` is already taken by a Worker, use a different project name like `linearvoid-site` and update the `projectName` and `PROJECT_NAME` values in the workflow.
