-- 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.

+  - **Playout**: automatic media normalization on upload (`media.NormalizeVideo`, `*.normalized.mp4`, statuses `ready`/`needs_normalization`/`normalizing`/`normalization_failed`, `POST /api/admin/media/{id}/normalize`); R2 segment retention (`cleanupOldRuns`, keep last `R2_KEEP_RUNS` runs, `R2_MAX_RETENTION_BYTES` cap); seamless looping (playlist SHA-256 fingerprint + `-start_number`); single `start-playout.sh` entrypoint + `-validate` mode; loop/cleanup metrics.
+  - **Application configuration**: thread-safe JSON runtime config store (`backend/chat/src/config/runtime.go`) shared with playout via `/app/playlist/config.json`; `GET/PUT /api/admin/config`; admin UI config form.
+  - **Matomo analytics**: public `GET /api/matomo` + viewer pageview snippet in `index.html`.
+  - **Chat user accounts**: register/login/logout/session endpoints, bcrypt hashing, `linearvoid_user_session` cookie, viewer sign-in UI.
+  - **DM history & search**: `GET /api/dm/history` (paginated) + `GET /api/dm/search` + DM search UI.
+  - **Chat UI**: typing indicator, user-list toggle, media status badges, "Add to playlist" gated to `ready`.
+  - **Prometheus TSDB retention**: `--storage.tsdb.retention.time=30d` + `--storage.tsdb.retention.size=15GB` in both compose files; alert rule count corrected 8 → 10.
+- Updated `docs/architecture/README.md` to reflect all `[Unreleased]` changes (normalization, looping, retention, runtime config, Matomo, user accounts, DM history/search, new API endpoints, module tables).
+- Released **1.0.13**: promoted changelog, bumped version, tagged and pushed.
+- Extended frontend test coverage: added `counter.test.ts`, reconnecting/typing/auth/websocket tests, admin failure + status-badge tests → 56 tests; statements 19.89% → 28.58% (CI coverage threshold passing).
+- Fixed Go test data race in `TestHandleAdminMediaByID_Normalize` (waits for async normalization goroutine) + shared in-memory SQLite via `SetMaxOpenConns(1)`.
+- Fixed viewer crash: `index.html` was missing the `#messages` chat container (stray `</section>`); restored structure + made `addMessage` defensive.
+- Set `Doto` as the body font (`--font-body`) and added Google Fonts links to admin + login pages.
+- Files changed: across `backend/chat`, `backend/playout`, `frontend`, `docs`, `docker-compose*.yml`, `.github/instructions/*`.

-## Plan
+## Playout / R2 manifest–segment layout mismatch
 
-### Phase 1: unblock playout test fixtures and lock down the source-media contract
+**Chosen approach: candidate (a)** — rewrite the live manifest so its media URIs point into the current run-scoped folder before the atomic R2 publish. Go change in `backend/playout/src/playlist.go`. The `linearvoid-media` Worker stays a faithful path→R2 mapper (no serve-time rewrite).
 
-- [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
+### Remaining — Validation
 
-### Phase 2: finish frontend coverage for the live viewer experience
+- [ ] Run playout (local or test lab), then:
+  - `curl https://media.linearvoid.tv/hls/playlist.m3u8` → 200, short TTL.
+  - Every URI in the manifest resolves `200` with `Cache-Control: public, max-age=31536000, immutable` (via the `linearvoid-media` Worker).
+  - Confirm manifest refresh + `CF-Cache-Status` progression and no 404 on segment fetch across a run loop.
+- [ ] Verify slate fallback still serves correctly after the rewrite change.
 
-- [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
+> Implementation (candidate a), Go unit tests, and documentation are complete — see [DONE.md](./DONE.md).
 
-### Phase 3: finish frontend coverage for the admin experience
+## Frontend Tests
 
-- [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
+### User Frontend
 
-### Phase 4: validate the R2 and edge-delivery path
+- [ ] Test coverage for all critical frontend components and interactions
+- [ ] Add code coverage reporting and enforce minimum coverage threshold in CI/CD pipeline
+- [ ] Document test cases and expected outcomes
 
-- [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)
+### Admin Frontend
 
-### Phase 5: complete manual Cloudflare and external-service setup
+- [ ] Test coverage for all critical admin UI components and interactions
+- [ ] Add code coverage reporting and enforce minimum coverage threshold in CI/CD pipeline
+- [ ] Document test cases and expected outcomes
 
-- [ ] 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`
+## Backend Integration Tests
 
-### Phase 6: rehearse production deployment end to end
+### Cloudflare R2
 
-- [ ] 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.

-## [Unreleased]
+## [1.1.0] - 2026-09-03
+
+### Added
+
+- **Cloudflare media edge worker (`linearvoid-media`)**: new self-contained project under `infrastructure/cloudflare/` — an R2-bound Worker owning `media.linearvoid.tv` that enforces immutable segment caching (`public, max-age=31536000, immutable`) and short-TTL live `.m3u8`, with HLS CORS/OPTIONS, byte-Range, and a `/health` probe. Includes Vitest unit tests + Miniflare/workerd R2 integration tests and production deploy via `.gitea/workflows/workers-media-deploy.yml`. Replaces the ad-hoc `worker.js`.
+- **Bash script ports**: Linux/macOS equivalents of the Windows ops/load-test scripts (`cache-hit-ratio`, `check-env`, `check-tokens`, loadtest run/summarize); `.ps1` files retained.
+- **Transient presence flash**: join/leave events show as a 3-second `#chat-flash` instead of permanent chat rows.
+
+### Changed
+
+- **Cloudflare Workers hosting**: frontend moved from Cloudflare Pages to the `linearvoid-frontend` static-assets Worker; docs now describe `linearvoid-frontend` (SPA) and `linearvoid-media` (edge HLS), correcting stale `worker.js` and R2 custom-domain wording.
+- **Docs de-Windows'd & condensed**: bash-first guides for `SETUP`, `DEPLOYMENT`, `API`, `MONITORING`, `STREAMING`, `COOLIFY`, incident runbook, scaling playbook, architecture README, and Prometheus metrics inventory.
+- **Compose port de-collision**: playout on host port `8081`, nginx moved to `8082` (`NGINX_PORT` default updated) to avoid Coolify-reserved ports.
+- **Playout**: R2 retention now by run count + byte cap (`R2_KEEP_RUNS` default 2, `R2_MAX_RETENTION_BYTES` default 10 GiB, new gauges) replacing the 24h time-based cleanup; default `HLS_SEGMENT_DURATION` 2s / `HLS_WINDOW_SIZE` 12; deduplicated, concurrent startup validation.
+- **Chat/UX**: 5s reconnect grace window (no join/leave spam); `system` messages no longer persisted; smaller `.message-text`; sidebar cleanup (removed DM search + Users toggle, login/register now a modal).
+- **Auth**: viewer session cookie uses `SameSite=None; Secure` over HTTPS (cross-site SPA) and `Lax` over plain HTTP.
+
+### Fixed
+
+- **Run-scoped R2 manifest URIs (playout)**: `publishManifest` now rewrites bare relative media URIs to the current run folder (`r-{runID}/…`) via `rewriteManifestToRun` before the atomic `.tmp` → `CopyObject` publish, so the live `hls/playlist.m3u8` references resolve against the run-scoped segment keys on `media.linearvoid.tv`. Skipped in slate mode. (Live validation pending — see `TODO.md`.)
+- **Cross-origin auth**: login/register API calls now prefix `VITE_PUBLIC_APP_URL` so the Workers-served SPA reaches the app origin.
+- **Duplicate chat history**: `connectWebSocket` clears messages on each (re)connect and the initial connect waits for session resolution.
+
+### Tests
+
+- WebSocket (`TestHub_Broadcast_SystemNotPersisted`, `TestHub_ReconnectGracePeriod`), handlers (`TestHandleAdminChatLog_ExcludesSystem`), frontend presence flash.
+- Playout: `TestCleanupOldRuns(_SizeCap)`, `TestR2KeepRuns`, `TestR2MaxRetentionBytes`, `TestR2RunFromKey`, `TestValidateWorkersConfig`, `TestValidatePlaylist_Dedup`.
+- Playout (run-scoped manifest rewrite): `TestRewriteManifestToRun`, `TestRewriteManifestToRun_AlreadyPrefixedUnchanged`, `TestRewriteManifestToRun_HandlesTSAndComments`, `TestRewriteManifestToRun_EmptyRunID`, `TestIsMediaURI`, `TestPublishManifest_RewritesToRunScopedURIs`, `TestPublishManifest_SlateNotRewritten`.
+- Cloudflare media worker: Vitest unit (`cacheControlForPath`, `contentTypeForPath`, `parseByteRange`) + Miniflare R2 integration (immutable segment, short-TTL manifest, Range `206`, `404`, OPTIONS, method guard).
+
+## [1.0.13] - 2026-08-13
+
+### Added
+
+- **Automatic media normalization on upload**: Chat backend auto-transcodes non-conforming uploads. New `media.NormalizeVideo` wraps ffmpeg with the Linear Void profile (H.264/AAC, 30fps, 2s keyframes, yuv420p, 48kHz stereo), re-verifies output with ffprobe, and writes `*.normalized.mp4`. Media records gain `normalizing` / `normalization_failed` statuses; `POST /api/admin/media/{id}/normalize` re-triggers manually. Admin UI shows a "Normalize" action with status polling.
+- **R2 segment retention**: Playout `cleanupOldSegments` deletes `hls/r-*/*` objects older than `R2_SEGMENT_RETENTION_HOURS` (default 24h), run hourly + at startup, never touching the live manifest. Exposes `linearvoid_playout_r2_cleanup_objects_total` metric. `.env.example` adds `R2_SEGMENT_RETENTION_HOURS`.
+- **Playout loop metrics**: `linearvoid_playout_loops_total` (clean completions) and `linearvoid_playout_run_duration_seconds` (last run duration).
+- **Runtime configuration store**: Thread-safe, JSON-persisted runtime config (`HLS_SEGMENT_DURATION`, `HLS_WINDOW_SIZE`, `MATOMO_URL`, `MATOMO_SITE_ID`) with typed getters/setters + validation, editable via `GET/PUT /api/admin/config`. Playout reads the shared `config.json` as env fallback.
+- **Matomo analytics**: Viewer pageview snippet in `index.html` driven by the public `GET /api/matomo` endpoint.
+- **Chat user accounts**: Register/login/logout (`POST /api/auth/register`, `/login`, `/logout`, `GET /api/auth/session`), bcrypt password hashing, `linearvoid_user_session` cookie, and a viewer sign-in UI.
+- **Private DM history & search**: `GET /api/dm/history` (paginated) and `GET /api/dm/search`, with a DM search UI in the viewer.
+- **Chat UI polish**: Typing indicator, user-list toggle, media status badges, and an "Add to playlist" action gated to `ready` media.
+
+### Changed
+
+- **Playout seamless looping**: `main()` now only resets HLS output when the playlist changed (SHA-256 `playlistRevision`), on crash/slate recovery, or first run; otherwise it continues segment numbering via `-start_number` and prunes stale segments. Eliminates the viewer gap on clean playlist loops.
+- **Single playout entrypoint**: `start-playout.sh` now runs `/app/playlist-manager -validate` then `exec`s the Go binary, removing the duplicate shell ffmpeg loop. Added a `-validate` mode to `main()`.
+- **Admin media library**: Shows status badges (`ready`/`needs_normalization`/`normalizing`/`failed`) and only offers "Add to playlist" for `ready` media; playlist entries show per-item status badges.
+- **Prometheus TSDB retention**: The `prometheus` service now sets `--storage.tsdb.retention.time=30d` and `--storage.tsdb.retention.size=15GB` (in both `docker-compose.yml` and `docker-compose.prod.yml`), so metrics older than 30 days are deleted.
+
+### Tests
+
+- Media: `TestNormalizationArgs`, `TestNormalizeVideo_FFmpegError`.
+- Handlers: `TestNormalizeMediaRecord_Success`, `TestNormalizeMediaRecord_Failure`, `TestHandleAdminMediaByID_Normalize`.
+- Playout: `TestCleanupOldSegments`, `TestR2SegmentRetentionHours`, `TestPlaylistFingerprint`, `TestHLSNextStartNumber`, `TestLoadSharedHLSConfig`.
+- Config: `runtime_test.go` (get/set, persist/reload, env fallback, validation).
+- Auth: `TestUserSessionStore`.
+- Handlers: config GET/PUT + validation, DM history/search, user register/login/session.
 
 ## [1.0.12] - 2026-08-11
 
@@ -13,7 +70,7 @@
 ### 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.
+- **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.

 ## Chat WebSocket API
 
-### Connect
+Connect: `GET /ws?username={name}&room={room}` — client/server exchange JSON messages.
 
-Endpoint:
+| Message (client→server) | Field                                                                            | Notes |
+| ----------------------- | -------------------------------------------------------------------------------- | ----- |
+| `type`                  | `public` for room chat, `private` for DM routing; `system` for moderation/events |       |
+| `room`                  | `main`; private DMs use `dm:userA-userB` (usernames sorted)                      |       |
+| `username`              | sender                                                                           |       |

-- GET /ws?username={name}&room={room}
-
-Client sends JSON messages over the socket.
-
-### Message Envelope (client -> server)
+Server→client envelope adds `"timestamp"` (ISO-8601, e.g. `2026-08-04T12:34:56Z`).
 
 ```json
-{
-  "room": "main",
-  "username": "viewer123",
-  "text": "hello world",
-  "type": "public"
-}
-```
-
-Notes:
-
-- type is usually public for room chat and private for DM room routing.
-- Private room names are formatted like dm:userA-userB (sorted usernames).
-- Moderation/system events are sent as type=system messages.

+# Coolify Deployment
+
+*Last Updated: 2026-08-28*
+
+Alternative deployment path for Linear Void using [Coolify](https://github.com/coollabsio/coolify/tree/v4.3.14) (v4.3.14), an open-source self-hostable PaaS that manages servers, apps, and databases over SSH. Drop-in alternative to the flows in [SETUP.md](./SETUP.md): local dev (`docker-compose.yml`) and test-lab/prod (`docker-compose.prod.yml` via Gitea Actions CD). Coolify deploys the same Compose stack through a web UI and its own Traefik reverse proxy for automatic HTTPS, domain routing, and one-click redeploys (no manual `DOCKER_HOST`).
+
+## Why Coolify
+
+- **Single control plane**: manage playout, chat, nginx, redis, db (plus exporters/monitoring) from one dashboard.
+- **Automatic TLS**: Let's Encrypt provisioning/renewal per app/domain, replacing the manual Cloudflare + nginx origin TLS setup for the app hostname.
+- **No vendor lock-in**: config lives on your server; containers keep running if you stop using Coolify — you only lose automation.
+- **Simpler cutover**: on Hetzner VPS provisioning, point Coolify at the new server and redeploy instead of editing CD `DOCKER_HOST`.
+
+> Replaces the *deployment orchestration* layer only. Cloudflare DNS, R2 media bucket, cache rules, and the edge Worker from [SETUP.md](./SETUP.md) are unchanged.
+
+## Prerequisites
+
+- Linux server with **Docker Engine** (any supported distro).
+- **SSH access** (root or passwordless `sudo`) from the Coolify install machine — Coolify provisions the target over SSH.
+- **2 GB RAM / 20 GB disk** minimum for Coolify itself (plus resources for the stack).
+- A domain pointed at the server for HTTPS (e.g. `linearvoid.tv`).
+- Ports `80` and `443` reachable for Traefik.
+- Gitea registry credentials (`CI_REGISTRY_USER` / `CI_REGISTRY_TOKEN`) if pulling prebuilt `playout`, `chat`, `nginx` images.
+
+## Installation
+
+Recommended on a dedicated server:
+
+```bash
+curl -fsSL https://cdn.coollabs.io/coolify/install.sh | bash
+```
+
+The installer boots a Docker-based Coolify instance and prints the URL and default credentials. Complete first-run setup in the dashboard. For non-interactive/offline installs, see the [installation docs](https://coolify.io/docs/installation) and [install script source](https://github.com/coollabsio/coolify/blob/v4.3.14/scripts/install.sh).
+
+## Add the Linear Void server
+
+1. **Servers → Add**.
+2. Choose your provider (or **Localhost** if Coolify runs on the same host as the stack).
+3. Provide SSH details; for a remote host Coolify validates and installs its agent.
+4. Confirm the server shows **Reachable** before creating resources.
+
+### Current topology (verified 2026-08-30)
+
+Active test-lab setup is **two-tier**:
+
+| Component | Host | Exposes | Docker TCP | Notes |
+|---|---|---|---|---|
+| **Coolify dashboard** | `192.168.88.18` | `https://coolify.allucanget.biz` via Cloudflare tunnel (`coolify-cloudflared`); dashboard at `8000` | No | Manages target servers over SSH |
+| **Deployment target** | `192.168.88.40` | `coolify-proxy` = Traefik on 80/443; port `8000` bound by Portainer, not Coolify | Yes | Per-server helpers (`coolify-proxy`, `coolify-sentinel`, `coolify-cloudflared`) + the stack via `docker-compose.prod.yml` (`linearvoid` compose project, 11 containers) |
+
+The main `coolify` app container runs only on the dashboard host `192.168.88.18`; Compose-resource services land on the target `192.168.88.40`. The dashboard host exposes no Docker TCP socket, so run the checks below against the **target** `192.168.88.40`:
+

+./scripts/check-tokens.sh   # Gitea registry, Cloudflare, R2, admin credential access
+```
+
+## Deploy the stack
+
+Deploy as a **Docker Compose** resource (not individual apps):
+
+1. **Projects → Add → Docker Compose**.
+2. Select the target server.
+3. In **Build Settings**, set the compose file source:
+   - **Git Repository** → point at `https://git.allucanget.biz/zwitschi/linearvoid.git`, compose file `docker-compose.prod.yml` (Coolify pulls on each redeploy).
+   - **Raw Compose** → paste `docker-compose.prod.yml` directly to manage manually.
+4. For the Git source, add the Gitea registry login as a **Deployment Key / environment secret** so `playout`, `chat`, `nginx` images can be pulled. Alternatively switch those services to `build:` blocks (as in `docker-compose.yml`) to build from source on the server.
+
+### Environment variables
+
+Map Linear Void's `.env` values into Coolify's **Environment Variables** tab:
+
+| Variable | Purpose |
+|---|---|
+| `DATABASE_URL` | `postgres://linearvoid:<password>@db:5432/linearvoid?sslmode=disable` |
+| `REDIS_URL` | `redis://redis:6379/0` |
+| `POSTGRES_PASSWORD` | DB password (used by `db` service) |
+| `ADMIN_USERNAME` / `ADMIN_PASSWORD` | Admin panel credentials |
+| `ADMIN_SESSION_TTL_HOURS` | Admin session lifetime |
+| `R2_ACCESS_KEY_ID` / `R2_SECRET_ACCESS_KEY` | Cloudflare R2 credentials |
+| `R2_BUCKET_NAME` / `R2_ENDPOINT` / `R2_REGION` | R2 bucket config (`R2_REGION=auto`) |
+| `MEDIA_DOMAIN` | `media.linearvoid.tv` |
+| `VITE_PUBLIC_APP_URL` | `https://linearvoid.tv` |
+| `VITE_PUBLIC_WS_URL` | `wss://linearvoid.tv/ws` |
+| `VITE_PUBLIC_HLS_URL` | `https://media.linearvoid.tv/hls/playlist.m3u8` |
+
+Keep internal service URLs on compose hostnames (`redis`, `db`) exactly as in `docker-compose.prod.yml`.
+
+### Persistent storage
+
+Named volumes (`redis-data`, `postgres-data`) and bind mounts under `./data` must be configured under **Persistent Storage** to survive redeploys:
+
+| Mount | Purpose |
+|---|---|
+| `data/playlist` | Playout playlist file |
+| `data/media` | Normalized source videos (read-only to playout) |
+| `data/hls` | Generated HLS manifests/segments |
+| `data/chat` | Chat service working data |
+| `data/slate` | Slate media |
+| `redis-data` | Redis append-only persistence |
+| `postgres-data` | PostgreSQL data directory |
+
+If Coolify doesn't auto-create the dirs, create them before first deploy:
+
+```bash
+mkdir -p data/playlist data/media data/hls data/chat
+```
+
+### Domains and proxy
+
+1. Assign the **nginx** service a public domain (e.g. `linearvoid.tv`); Traefik terminates TLS and forwards to `nginx`.
+2. Set **Ports Exposes** so Traefik targets the nginx port (`80` inside container, mapped from `${NGINX_PORT:-8082}:80`).
+3. Do **not** publicly expose playout (`8081`) or chat (`3000`) health ports — keep them internal and route through nginx.
+4. For `media.linearvoid.tv`, keep serving HLS from the R2 custom domain (per SETUP.md) rather than routing through Coolify, so segments stay on Cloudflare's edge cache.
+
+## Post-deploy verification
+
+- `docker compose ps` on the server shows all services healthy.
+- Playout health: `https://<host>/health` via nginx (internal `:8081/health`).
+- Chat health: internal `:3000/health`.
+- HLS written to `data/hls` and served from `media.linearvoid.tv`.
+- Chat WebSocket connects over `wss://linearvoid.tv/ws`.
+- Admin login works at `/admin` with configured credentials.
+
+## Monitoring
+
+Coolify exposes container logs/basic metrics per resource. The stack ships Prometheus + Grafana (`monitoring/`) plus nginx/redis exporters. To reach them via Coolify, expose Grafana on a restricted subdomain (e.g. `grafana.linearvoid.tv`) and keep Prometheus internal, mirroring SETUP.md access guidance.
+
+## Cutover from Gitea CD
+
+1. Deploy the stack as a Coolify compose resource (above).
+2. Point Cloudflare DNS for `linearvoid.tv` / `www` at the server IP (proxied).
+3. Disable (or keep as fallback) the `cd` job in the Gitea workflow so the two orchestrators don't fight over the same `DOCKER_HOST`.
+4. Keep the Gitea **CI** (build + push images) job so Coolify keeps pulling `:latest` from the registry.
+
+## Troubleshooting
+
+- **Image pull fails**: set Gitea registry credentials in the compose secret store, or switch services to `build:` blocks.
+- **Healthchecks fail**: confirm `curl` exists in the built images (healthchecks rely on it).
+- **TLS errors**: check the domain's DNS points at the Coolify server and ports `80`/`443` are open.
+- **HLS not updating**: verify `data/hls` is writable and playout restarts cleanly; see SETUP.md normalization troubleshooting.
+- **Ports conflict**: Coolify's Traefik binds `80`/`443`; do not also map those to the host in the compose file.

+**High cardinality / slow queries**: reduce unneeded labels; limit expensive panels; tune retention and query windows.
 
 ## Operational Recommendations
 
 - Keep alert thresholds tied to actual user impact.
 - Review dashboards after each release that changes endpoints or metrics names.
 - Periodically test alert routing and incident response flow.
+- Retention: **30 days** time-based plus **15GB** size cap (`--storage.tsdb.retention.time=30d --storage.tsdb.retention.size=15GB` on the `prometheus` service in `docker-compose.yml` and `docker-compose.prod.yml`). Increase the size cap before extending the time window so the TSDB does not hit the disk limit first.

 # Linear Void Setup Guide
 
-This guide covers prerequisites, environment setup, running the application locally and in production, and troubleshooting. It references the [architecture documentation](./docs/architecture/README.md)(`docs/architecture/README.md`).
+**Last Updated**: 2026-08-03
+
+Prerequisites, environment setup, and running the app locally and in production. Architecture: [`docs/architecture/README.md`](./architecture/README.md).
 
 ## Prerequisites
 
-- **Docker & Docker Compose**: Required for running the full stack (playout, chat, nginx, redis, db, prometheus, grafana). Install from [docker.com](https://www.docker.com).
-- **Node.js 22+**: Required for frontend development and production builds (`cd frontend && npm install && npm run build`).
-- **npm**: Installed with Node.js and used for the frontend dependency installation and Vite workflow.
-- **Go 1.23+**: Recommended when working on the Go services outside Docker (`backend/chat`, `backend/playout`).
-- **FFmpeg**: Used by the playout service for HLS generation. Install via `apt install ffmpeg` (Linux), Homebrew (macOS), or Winget (Windows).
-- **Git**: For cloning and version control.
-- **Cloudflare Account**: For R2 storage and CDN (free tier sufficient for most use cases).
-- **Gitea Account**: Required if you want to push images to the self-hosted registry or use the repository's CI/CD flow.
-  - Set up the required Actions secrets in Gitea at: [https://git.allucanget.biz/zwitschi/linearvoid/settings/actions/secrets](https://git.allucanget.biz/zwitschi/linearvoid/settings/actions/secrets)
-  - Add the following secrets:
-    - `CI_REGISTRY_USER`: Your Gitea username (e.g., `zwitschi`)
-    - `CI_REGISTRY_TOKEN`: A Gitea Personal Access Token with `write:packages` scope
-    - `ADMIN_USERNAME`: The administrator username for the production admin panel (e.g., `admin`)
-    - `ADMIN_PASSWORD`: A strong password for the production admin panel
-    - `DATABASE_URL`: The production database connection string (e.g., `postgres://linearvoid:<password>@db:5432/linearvoid?sslmode=disable`)
-- **Hetzner Cloud Account** (optional for production): For the US-East VPS (Ashburn, VA recommended per ADR-001).
+- **Docker + Docker Compose** — runs the full stack (playout, chat, nginx, redis, db, prometheus, grafana).
+- **Node.js 22+ / npm** — frontend dev and builds (`cd frontend && npm install && npm run build`).
+- **Go 1.25+** — working on the Go services outside Docker.
+- **FFmpeg** — playout HLS generation (`apt install ffmpeg`).
+- **Git**.
+- **Cloudflare account** — R2 storage + CDN.
+- **Gitea account** — image registry + CI/CD. Set Actions secrets at `https://git.allucanget.biz/zwitschi/linearvoid/settings/actions/secrets`: `CI_REGISTRY_USER`, `CI_REGISTRY_TOKEN` (scope `write:packages`), `ADMIN_USERNAME`, `ADMIN_PASSWORD`, `DATABASE_URL`.
+- **Hetzner Cloud (optional, prod)** — US-East VPS (Ashburn, VA per ADR-001).

-**Test Lab (active):** Internal network `192.168.88.0/24`, host `192.168.88.40`. Receives automated CD deploys from Gitea Actions. Used for integration testing and staging validation.
-
-**Production (pending):** Hetzner Cloud VPS, Ashburn VA. Not yet provisioned. CD workflow and compose files are ready — only `DOCKER_HOST` needs changing. See Production Deployment section in [DEPLOYMENT.md](./DEPLOYMENT.md) for cutover plan.
-
-## Development Prerequisites
-
-- **Frontend dependencies**: Run `cd frontend && npm install` before `npm run dev` or `npm run build`.
-- **Docker build support**: Local development expects Docker to be able to build the `chat`, `playout`, and `nginx` images referenced in `docker-compose.yml`.
-- **Data directories**: Create `data/playlist`, `data/media`, `data/hls`, and `data/chat` before the first run so bind mounts resolve cleanly.
-- **Database choice**: The stack defaults to PostgreSQL in `docker-compose.yml`. If you want SQLite for local-only development, update `DATABASE_URL` in `.env` accordingly.
-- **Redis availability**: Chat presence, rate limiting, and pub/sub require Redis. The compose stack provides it automatically.
-- **Video inputs**: Source videos should be normalized before playout. If the playlist contains invalid files, the playout container will fail its validation flow.

 ## Environment Setup
 
-1. **Clone the Repository** (if not already done):
-
-   ```bash
-   git clone https://git.allucanget.biz/zwitschi/linearvoid.git
-   cd linearvoid
-   ```
-
-2. **Copy Environment File**:
-
-   ```bash
-   cp .env.example .env
-   ```
-
-3. **Configure `.env`** (edit with your values):
-
-   ```env
-   # Cloudflare R2 (required for video storage and $0 egress)
-   R2_ACCESS_KEY_ID=your-r2-access-key
-   R2_SECRET_ACCESS_KEY=your-r2-secret-key
-   R2_BUCKET_NAME=linearvoid-media
-   R2_ENDPOINT=https://your-account-id.r2.cloudflarestorage.com
-   R2_REGION=auto
-
-   # Cloudflare (for custom domain and cache rules)
-   CLOUDFLARE_API_TOKEN=your-cloudflare-api-token
-   CLOUDFLARE_ACCOUNT_ID=your-account-id
-   MEDIA_DOMAIN=media.linearvoid.tv
-
-   # Public frontend URLs
-   # Preferred local setup uses the real public domains through Cloudflare and Nginx Proxy Manager.
-   VITE_PUBLIC_APP_URL=https://linearvoid.tv
-   VITE_PUBLIC_WS_URL=wss://linearvoid.tv/ws
-   VITE_PUBLIC_HLS_URL=https://media.linearvoid.tv/hls/playlist.m3u8
-   VITE_PUBLIC_ADMIN_DEFAULT_MODERATOR=admin
-   VITE_PUBLIC_ADMIN_DEFAULT_ROOM=main
-   VITE_PUBLIC_ADMIN_MODERATION_LOG_LIMIT=50
-   ADMIN_USERNAME=admin
-   ADMIN_PASSWORD=change-me
-   ADMIN_SESSION_TTL_HOURS=12
-   # Optional direct-local fallback when bypassing the public proxy:
-   # VITE_PUBLIC_APP_URL=http://localhost
-   # VITE_PUBLIC_WS_URL=ws://localhost/ws
-   # VITE_PUBLIC_HLS_URL=http://localhost/hls/playlist.m3u8
-
-   # Gitea Container Registry (for self-hosted Docker images)
-   CI_REGISTRY_URL=git.allucanget.biz
-   CI_REGISTRY_USER=your-gitea-username
-   CI_REGISTRY_TOKEN=your-gitea-token
-   CI_REGISTRY_NAMESPACE=zwitschi/linearvoid
-   # Gitea API access (optional, for CI/release automation)
-   CI_SERVER_URL=https://git.allucanget.biz
-
-   # Chat / Database
-   DATABASE_URL=postgres://linearvoid:linearvoid@db:5432/linearvoid?sslmode=disable
-   # or for SQLite-only local development:
-   # DATABASE_URL=sqlite://./data/chat.db
-   REDIS_URL=redis://redis:6379/0
-
-   # Ports (for local development)
-   PLAYOUT_PORT=8080
-   CHAT_PORT=3000
-   NGINX_PORT=80
-
-   # Playout Configuration
-   PLAYLIST_PATH=/app/playlist.txt
-   HLS_SEGMENT_DURATION=6
-   HLS_WINDOW_SIZE=24
-
-   # Logging / Monitoring
-   LOG_LEVEL=info
-   PROMETHEUS_PORT=9090
-   GRAFANA_PORT=3001
-
-   # Development flags
-   NODE_ENV=development
-   GO_ENV=development
-   ```
-
-4. **Check local value overrides for Docker Compose**:
-   - `docker-compose.yml` builds images locally and maps the frontend build output from `frontend/dist` into nginx.
-   - `docker-compose.prod.yml` pulls prebuilt images from the Gitea registry.
-   - Internal container-to-container URLs should use compose hostnames, for example `REDIS_URL=redis://redis:6379/0` and `DATABASE_URL=postgres://linearvoid:<password>@db:5432/linearvoid?sslmode=disable`.
-   - For production public routing, set `VITE_PUBLIC_APP_URL=https://linearvoid.tv`, `VITE_PUBLIC_WS_URL=wss://linearvoid.tv/ws`, and `VITE_PUBLIC_HLS_URL=https://media.linearvoid.tv/hls/playlist.m3u8`.
-
-5. **Create Data Directories**:
-
-   ```bash
-   mkdir -p data/playlist data/media data/hls data/chat
-   ```
-
-6. **Prepare Sample Videos** (optional):
-   - Place normalized MP4 files in `data/media/`.
-   - Create a `data/playlist/playlist.txt` with paths (see ADR-001 for normalization requirements).
+1. `git clone https://git.allucanget.biz/zwitschi/linearvoid.git && cd linearvoid`
+2. `cp .env.example .env` then replace placeholders.
+3. Compose overrides: `docker-compose.yml` builds images locally and mounts `frontend/dist` into nginx; `docker-compose.prod.yml` pulls prebuilt images from Gitea.
+   - Internal URLs use compose hostnames: `REDIS_URL=redis://redis:6379/0`, `DATABASE_URL=postgres://linearvoid:<pw>@db:5432/linearvoid?sslmode=disable`.
+   - Public routing: `VITE_PUBLIC_APP_URL=https://linearvoid.tv`, `VITE_PUBLIC_WS_URL=wss://linearvoid.tv/ws`, `VITE_PUBLIC_HLS_URL=https://media.linearvoid.tv/hls/playlist.m3u8`.
+4. Create data dirs: `mkdir -p data/playlist data/media data/hls data/chat`
+5. Optional: place normalized MP4s in `data/media/` and create `data/playlist/playlist.txt` (see ADR-001 for normalization).
 
 ## Gitea Setup
 
-1. **Create or verify a Gitea user**:
-   - The user should have access to the repository and permission to read from the container registry.
-
-2. **Create an access token**:
-   - Generate a token with the scopes needed for package/registry access and, if applicable, repository automation.
-   - Store it as `CI_REGISTRY_TOKEN` in `.env`.
-
-3. **Configure Gitea Actions Secrets**:
-   - Go to the repository settings page: [https://git.allucanget.biz/zwitschi/linearvoid/settings/actions/secrets](https://git.allucanget.biz/zwitschi/linearvoid/settings/actions/secrets)
-   - Add the following secrets to enable automated CI/CD and production deployment:
-     - `CI_REGISTRY_USER`: Your Gitea username (e.g., `zwitschi`).
-     - `CI_REGISTRY_TOKEN`: Your Gitea Personal Access Token with `write:packages` scope.
-     - `ADMIN_USERNAME`: The administrator username for the production admin panel (e.g., `admin`).
-     - `ADMIN_PASSWORD`: A strong password for the production admin panel.
-     - `DATABASE_URL`: The production database connection string (e.g., `postgres://linearvoid:<password>@db:5432/linearvoid?sslmode=disable`).
-
-4. **Configure registry variables**:
-   - Set `CI_REGISTRY_URL` to the Gitea host.
-   - Set `CI_REGISTRY_NAMESPACE` to the image namespace, for example `zwitschi/linearvoid`.
-   - Set `CI_REGISTRY_USER` to the account that will push or pull images.
-
-5. **Authenticate Docker to the registry**:
-
-   ```bash
-   docker login git.allucanget.biz
-   ```
-
-6. **Build and publish images when needed**:
-   - Local development uses `docker-compose.yml`, which builds from source.
-   - Production uses `docker-compose.prod.yml`, which expects the `playout`, `chat`, and `nginx` images to exist in the configured Gitea registry namespace.
-
-7. **Validate image availability**:
-   - Before a production rollout, verify that the expected `:latest` tags can be pulled from the registry on the target server.
+1. User with repo + registry access; generate a token (scope `write:packages`) stored as `CI_REGISTRY_TOKEN`.
+2. Set Actions secrets (see Prerequisites) to enable automated CI/CD and deploys.
+3. Set registry vars: `CI_REGISTRY_URL`, `CI_REGISTRY_NAMESPACE` (e.g. `zwitschi/linearvoid`), `CI_REGISTRY_USER`.
+4. Auth: `docker login git.allucanget.biz`.
+5. Local dev builds from source; prod pulls `playout`, `chat`, `nginx` images from the registry namespace. Verify `:latest` tags exist before rollout.
 
 ## Cloudflare R2 Setup
 
-1. **Create an R2 bucket**:
-   - Create a bucket such as `linearvoid-media` in Cloudflare R2.
-   - Keep the bucket name aligned with `R2_BUCKET_NAME` in `.env`.
-
-2. **Generate R2 API credentials**:
-   - Create an access key pair with read/write permissions for the bucket.
-   - Set `R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, and `R2_REGION=auto` in `.env`.
-
-3. **Find the S3 endpoint**:
-   - Use the account-scoped endpoint format `https://<account-id>.r2.cloudflarestorage.com`.
-   - Store the account ID in both `R2_ENDPOINT` and `CLOUDFLARE_ACCOUNT_ID` where applicable.
-
-4. **Bind a custom media domain**:
-   - Attach a domain such as `media.linearvoid.tv` to the bucket.
-   - Set `MEDIA_DOMAIN` to that hostname.
-
-5. **Configure app-domain DNS and TLS**:
-   - Point `linearvoid.tv` to the public entrypoint serving nginx.
-   - Point `www.linearvoid.tv` to the same target and redirect it to `https://linearvoid.tv`.
-   - Keep `media.linearvoid.tv` on the R2 custom domain path so HLS delivery stays split from the app origin.
-   - Use Cloudflare proxied DNS with Full (strict) TLS so browser traffic uses `https://linearvoid.tv`, `wss://linearvoid.tv/ws`, and `https://media.linearvoid.tv`.
-
-6. **Apply cache behavior**:
-   - Configure the `.m4s` and `.m3u8` cache rules from [cache-rules](../docs/infrastructure/cloudflare/cache-rules.md).
-   - Enable Smart Tiered Cache for the R2-backed hostname.
-   - If you need header normalization for immutable segment caching, deploy `infrastructure/cloudflare/worker.js` to the same zone.
-
-7. **Verify access**:
-   - Confirm uploads with an S3-compatible client such as `aws s3 ls --endpoint-url <R2_ENDPOINT>`.
-   - After deployment, check Cloudflare analytics for cache hit ratio and origin request volume.
-
-## Cloudflare
-
-Use this section for full edge setup (DNS, Pages, cache, security, and monitoring).
-
-Execution tracker: `docs/operations/cloudflare-uptimerobot-checklist.md`.
-
-### 1. DNS Setup
-
-1. Add apex record for `linearvoid.tv` pointing to Cloudflare Pages target.
-2. Add `www` CNAME to Cloudflare Pages and configure redirect to `https://linearvoid.tv`.
-3. Add `media.linearvoid.tv` for split-domain HLS delivery.
-4. Keep all records proxied (orange cloud) unless troubleshooting requires DNS-only mode.
-
-### 2. R2 Bucket
-
-1. Create bucket `linearvoid-media`.
-2. Set location hint to `enam` (US-East).
-3. Attach custom domain `media.linearvoid.tv` to the bucket.
-4. Verify object read works from the custom domain.
-
-### 3. Cache Rules
-
-Configure Cloudflare Cache Rules:
-
-1. HLS segment files (`*.ts`, `*.m4s`):
-   - Cache: eligible
-   - Edge TTL: `31536000`
-   - Browser TTL: long-lived
-   - Cache key: include full path
-2. HLS manifests (`*.m3u8`):
-   - Cache: eligible
-   - Edge TTL: `2s`
-   - Revalidation: enabled
-3. Static assets (`*.js`, `*.css`):
-   - Cache: eligible
-   - Edge TTL: `1y`
-   - Browser TTL: long-lived
-   - Cache key: include full path
-4. Validate behavior using response headers:
-   - `Cf-Cache-Status` should move from `MISS` to `HIT` for hot objects
-
-Reference: [cache-rules](../docs/infrastructure/cloudflare/cache-rules.md).
-
-### 4. Cloudflare Pages
-
-Also see [the automated Gitea Actions deployment guide](./operations/gitea-cloudflare-pages.md).
-
-Manual setup:
-
-1. Connect Gitea repository to Cloudflare Pages.
-2. Build command:
-
-   ```bash
-   cd frontend && npm run build
-   ```
-
-3. Output directory:
-
-   ```text
-   frontend/dist
-   ```
-
-4. Configure production domain to `linearvoid.tv`.
-
-### 5. Tiered Cache
-
-1. Enable Smart Tiered Cache in Cloudflare dashboard.
-2. Warm a segment and manifest path.
-3. Confirm tiered behavior through repeated requests and `Cf-Cache-Status: HIT`.
-
-### 6. WAF and Bot Protection
-
-1. Enable OWASP Managed Ruleset.
-2. Start in `Simulate` mode.
-3. Review events for 48 hours.
-4. Switch to `Block` once false positives are addressed.
-5. Enable Bot Fight Mode.
-
-### 7. Rate Limiting
-
-Create rules:
-
-1. Path: `/api/admin/login`
-2. Path: `/api/admin/*`
-3. Threshold: `10 requests / 10 seconds / IP`
-4. Action: `Managed Challenge`
-
-### 8. HTTPS and WSS
-
-1. Enable `Always Use HTTPS`.
-2. Enable HSTS with:
-   - `max-age=31536000`
-   - `includeSubDomains`
-   - `preload`
-3. Minimum TLS version: `1.2`.
-4. Keep SSL mode at `Full (strict)` when origin certs are valid.
-5. Enforce HTTPS redirect at both layers:
-   - Cloudflare edge
-   - nginx origin
-6. Validate websocket endpoint uses `wss://linearvoid.tv/ws`.
-
-### 9. UptimeRobot Monitors
-
-Create external monitors:
-
-1. HTTP monitor:
-   - URL: `https://linearvoid.tv/health`
-   - Interval: 5 minutes
-2. Keyword monitor:
-   - URL: `https://linearvoid.tv/hls/playlist.m3u8`
-   - Keyword: `#EXTM3U`
-   - Interval: 5 minutes
-3. Alert policy:
-   - Trigger on 2 consecutive failures
-   - Notify via email and Discord/Slack webhook
-
-### 10. Verification Checklist
-
-1. DNS resolves for `linearvoid.tv`, `www.linearvoid.tv`, and `media.linearvoid.tv`.
-2. Pages serves frontend for apex and `www` redirects correctly.
-3. HLS segments are cacheable long-term, manifests refresh every ~2s.
-4. Admin paths are rate-limited and WAF events are visible.
-5. HTTPS and WSS both succeed with valid certificates.
-6. UptimeRobot alerts fire as expected when endpoints are intentionally made unavailable.
+1. Create R2 bucket (e.g. `linearvoid-media`, matching `R2_BUCKET_NAME`); generate an access key pair → `R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, `R2_REGION=auto`.
+2. S3 endpoint: `https://<account-id>.r2.cloudflarestorage.com` → `R2_ENDPOINT`.
+3. Attach `media.linearvoid.tv` as custom media domain → `MEDIA_DOMAIN`; add CORS allowing `https://linearvoid.tv` GET for HLS delivery.
+4. Point `linearvoid.tv` (+ `www` redirect) at the app entrypoint; keep `media.*` on R2. Proxied DNS, TLS **Full (strict)**.
+5. Apply the `.m4s`/`.m3u8` cache rules from [`cache-rules.md`](./infrastructure/cloudflare/cache-rules.md); enable Smart Tiered Cache; deploy the [`linearvoid-media` worker](../infrastructure/cloudflare/) on `media.linearvoid.tv` (replace the R2 bucket's direct custom-domain binding on that host) to enforce immutable segment caching + HLS CORS.
+6. Verify: `aws s3 ls --endpoint-url $R2_ENDPOINT`; check cache hit ratio after serving traffic.

-   npm run dev
-   ```
+Deploy to `192.168.88.40` over Docker's TCP socket (port `2375`).
 
-   The dev server runs on <http://localhost:5173>. It proxies API calls to the backend services.
+Enable TCP on Alpine host — edit `/etc/conf.d/docker`:
 
-4. **Build frontend assets for nginx-backed local runs**:
+```bash
+DOCKER_OPTS="-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375"
+```
 
-   ```bash
-   cd frontend
-   npm install
-   npm run build
-   ```
+Then `rc-service docker restart`; verify with `netstat -tlnp | grep 2375`; allow port `2375` from `192.168.88.0/24` in the firewall.
 
-   The local nginx container serves `frontend/dist`, so rebuilding the frontend is required before validating production-like static output.
+Deploy from a machine with the Docker CLI:
 
-5. **Stop Services**:
+```bash
+export DOCKER_HOST="tcp://192.168.88.40:2375"

-### Local Test Environment Deployment (Remote Docker Host)
+### Coolify deployment
 
-For testing deployments on a local network server without setting up a full production VPS, you can deploy directly to a remote Docker host (e.g., a home lab server or test machine) using Docker's TCP socket.
+Coolify replaces the Gitea CD `DOCKER_HOST` orchestration (Cloudflare DNS/R2/cache unchanged). Install (`curl -fsSL https://cdn.coollabs.io/coolify/install.sh | bash`), add the target server via SSH, create a Docker Compose resource from `docker-compose.prod.yml` (or the repo), configure env vars in Coolify's store, map persistent `data/` and named volumes, and assign `linearvoid.tv` to nginx for Traefik TLS. Full walkthrough: [`COOLIFY.md`](./COOLIFY.md).
 
-#### Test Environment Prerequisites
+### Production setup
 
-- A remote server running Docker at IP `192.168.88.40` (running Alpine Linux).
-- Docker TCP socket enabled and listening on port `2375` on the remote server.
+1. Provision a Linux VPS (Docker, Compose, Git); open HTTP/HTTPS ports.
+2. `git clone … && cd linearvoid && cp .env.example .env`.
+3. Set production `.env`: strong `POSTGRES_PASSWORD`/`GRAFANA_PASSWORD`, compose-hostname internal URLs, `MEDIA_DOMAIN=media.linearvoid.tv`, public `VITE_PUBLIC_*` URLs. For local-only testing bypassing the proxy, use `http://localhost`/`ws://localhost/ws`/`http://localhost/hls/playlist.m3u8`.
+4. `mkdir -p data/playlist data/media data/hls data/chat`.
+5. Ensure `playout`, `chat`, `nginx` images exist in the registry; `docker login` from the VPS.
+6. Deploy: `docker compose -f docker-compose.prod.yml pull && docker compose -f docker-compose.prod.yml up -d`.
+7. Verify: `docker compose -f docker-compose.prod.yml ps`, health endpoints, HLS written to `data/hls`, media domain serves via Cloudflare.
+8. Harden: HTTPS in front of nginx (Cloudflare, `www` → apex), restrict Grafana/Prometheus to trusted IPs, run under systemd for auto-start.
 
-##### Enabling Docker TCP Socket on Alpine Linux
+### Production (Hetzner VPS + Cloudflare)
 
-To allow the Gitea Actions runner (or your local machine) to deploy to the remote Alpine host, you must configure the Docker daemon to listen on the TCP socket:
+1. Provision CX22 in Ashburn, VA (ADR-001).
+2. Cloudflare: R2 bucket (`enam` hint), deploy the [`linearvoid-media` worker](../infrastructure/cloudflare/) on `media.linearvoid.tv` + cache rules, `linearvoid.tv`/`www` at the app entrypoint with `www`→apex redirect, Full (strict) TLS.
+3. Deploy from the project: `docker compose -f docker-compose.prod.yml up -d` (or pull from Gitea registry); manage under systemd.
+4. Monitoring: Grafana dashboards from `monitoring/grafana/`.
 
-1. Edit `/etc/conf.d/docker` on the Alpine host:
-
-   ```bash
-   vi /etc/conf.d/docker
-   ```
-
-2. Update the `DOCKER_OPTS` line to include both the unix socket and the TCP socket:
-
-   ```bash
-   DOCKER_OPTS="-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375"
-   ```
-
-3. Restart the Docker service:
-
-   ```bash
-   rc-service docker restart
-   ```
-
-4. Verify that Docker is listening on port `2375`:
-
-   ```bash
-   netstat -tlnp | grep 2375
-   ```
-
-5. Ensure any firewall (like `awall` or `iptables`) on the Alpine host allows incoming traffic on port `2375` from your local network subnet (e.g., `192.168.88.0/24`).
-
-#### Deployment Steps
-
-1. **Configure Docker CLI to use the Remote Host**:
-   You can point your local Docker CLI to the remote server by setting the `DOCKER_HOST` environment variable:
-   - **PowerShell (Windows)**:
-
-     ```powershell
-     $env:DOCKER_HOST="tcp://192.168.88.40:2375"
-     ```
-
-   - **Bash (Linux/macOS)**:
-
-     ```bash
-     export DOCKER_HOST="tcp://192.168.88.40:2375"
-     ```
-
-2. **Verify Connection**:
-   Run `docker info` to confirm your local CLI is communicating with the remote server at `192.168.88.40`:
-
-   ```bash
-   docker info
-   ```
-
-   The output should show the remote server's hostname and system details.
-
-3. **Deploy the Stack**:
-   With `DOCKER_HOST` set, any `docker` or `docker compose` commands you run locally will execute directly on the remote server.
-   - **Deploy from Registry (Production-like)**:
-
-     ```bash
-     docker compose -f docker-compose.prod.yml pull
-     docker compose -f docker-compose.prod.yml up -d --remove-orphans
-     ```
-
-   - **Build and Deploy from Source**:
-
-     ```bash
-     docker compose up -d --build
-     ```
-
-4. **Access the Test Environment**:
-   - Playout Health: `http://192.168.88.40:8081/health`
-   - Chat Health: `http://192.168.88.40:3000/health`
-   - Nginx Entrypoint: `http://192.168.88.40:8080` (or the port mapped to `NGINX_PORT` in `.env`)
-
-5. **Reset to Local Docker Host**:
-   Once testing is complete, clear the `DOCKER_HOST` variable to point back to your local machine:
-   - **PowerShell**:
-
-     ```powershell
-     Remove-Item env:DOCKER_HOST
-     ```
-
-   - **Bash**:
-
-     ```bash
-     unset DOCKER_HOST
-     ```
-
-### Production Setup Guide
-
-1. **Prepare the target host**:
-   - Provision a Linux VPS with Docker Engine, Docker Compose, Git, and enough disk for media, HLS output, PostgreSQL, Redis persistence, and monitoring data.
-   - Open the ports required for HTTP/HTTPS and any restricted monitoring access you intend to expose.
-
-2. **Clone the repository and create the environment file**:
-
-   ```bash
-   git clone https://git.allucanget.biz/zwitschi/linearvoid.git
-   cd linearvoid
-   cp .env.example .env
-   ```
-
-3. **Set production-safe `.env` values**:
-   - Replace placeholder secrets.
-   - Use compose-network hostnames for internal services, for example `redis` and `db`.
-   - Set strong values for `POSTGRES_PASSWORD` and `GRAFANA_PASSWORD`.
-   - Keep `MEDIA_DOMAIN`, R2 credentials, and Gitea registry values consistent with the external infrastructure.
-   - Set `MEDIA_DOMAIN=media.linearvoid.tv`.
-   - Set `VITE_PUBLIC_APP_URL=https://linearvoid.tv`, `VITE_PUBLIC_WS_URL=wss://linearvoid.tv/ws`, and `VITE_PUBLIC_HLS_URL=https://media.linearvoid.tv/hls/playlist.m3u8`.
-   - If you intentionally bypass the public proxy for local-only testing, switch those values to `http://localhost`, `ws://localhost/ws`, and `http://localhost/hls/playlist.m3u8`.
-
-4. **Create runtime directories on the server**:
-
-   ```bash
-   mkdir -p data/playlist data/media data/hls data/chat
-   ```
-
-5. **Publish or verify required images in Gitea**:
-   - Ensure the `playout`, `chat`, and `nginx` images exist under `${CI_REGISTRY_URL}/${CI_REGISTRY_NAMESPACE}`.
-   - Log in to the registry from the VPS before pulling.
-
-6. **Deploy the production stack**:
-
-   ```bash
-   docker compose -f docker-compose.prod.yml pull
-   docker compose -f docker-compose.prod.yml up -d
-   ```
-
-7. **Run post-deploy verification**:
-   - Check `docker compose -f docker-compose.prod.yml ps`.
-   - Confirm nginx, chat, and playout health endpoints respond.
-   - Verify that HLS output is being written to `data/hls` and that the media domain serves manifests and segments through Cloudflare.
-
-8. **Harden and operate the deployment**:
-   - Put HTTPS in front of nginx using Cloudflare or another reverse proxy, with `linearvoid.tv` as canonical app host and `www.linearvoid.tv` redirected.
-   - Restrict Grafana and Prometheus exposure to trusted IPs or a private network.
-   - Run the stack under systemd or another service manager if you need auto-start behavior outside Docker restart policies.
-
-### Production Deployment (Hetzner VPS + Cloudflare)
-
-1. **Provision VPS**: Use Hetzner Cloud CX22 in Ashburn, VA (per ADR-001).
-2. **Configure Cloudflare**:
-   - Create R2 bucket with `enam` location hint.
-   - Set up custom media domain (`media.linearvoid.tv`) with the cache rules from [cache-rules](../docs/infrastructure/cloudflare/cache-rules.md).
-   - Point `linearvoid.tv` and `www.linearvoid.tv` at the app entrypoint, then redirect `www` to the apex domain.
-   - Use Full (strict) TLS for both app and media hostnames.
-   - Apply the Worker from `infrastructure/cloudflare/worker.js` for advanced header management.
-3. **Deploy**:
-   - Copy the project to the VPS.
-   - Use production compose: `docker compose -f docker-compose.prod.yml up -d`
-   - Or pull from Gitea registry: `docker compose -f docker-compose.prod.yml pull && docker compose -f docker-compose.prod.yml up -d`
-   - Configure systemd to manage the Docker Compose stack.
-4. **Monitoring**: Access Grafana at the exposed port for dashboards (included in `monitoring/grafana/dashboard.json`).
-
-See `docs/architecture/README.md` for the full arc42 documentation and the ADRs for architectural decisions.
+See `docs/architecture/README.md` (arc42) and the ADRs for decisions and cost/scaling guidance (ADR-001).
 
 ## Troubleshooting
 
-- **R2 Upload Fails**: Check credentials in `.env` and ensure the bucket exists. Verify with `aws s3 ls --endpoint-url=$R2_ENDPOINT`.
-- **Normalization Errors**: Run `backend/playout/start-playout.sh` manually to see ffprobe output. All videos must be H.264/AAC, 30 fps constant, 2s keyframes (ADR-001).
-- **Chat Not Connecting**: Check Redis connection and WebSocket URL. The health check at `/health` should return 200.
-- **Cache Not Working**: Verify Cloudflare cache rules (`.m4s` = long TTL immutable, `.m3u8` = short TTL). Check cache hit ratio in Cloudflare dashboard.
-- **Docker Issues**: Run `docker compose logs` for service-specific errors. Ensure ports are not in use.
-- **Admin Interface**: Ensure `ADMIN_USERNAME`, `ADMIN_PASSWORD`, and `ADMIN_SESSION_TTL_HOURS` are set. `/admin/` and `/api/admin/*` are protected by a session-based login flow.
-- **Production Pull Fails**: Confirm `docker login` to Gitea succeeded on the server and the image tags referenced by `docker-compose.prod.yml` exist.

+Segment boundaries must align with keyframes; timestamps must stay monotonic across item boundaries. If FFmpeg cannot preserve a seamless timeline, insert `#EXT-X-DISCONTINUITY` and publish the corresponding new init segment.
 
-Segment boundaries must align with keyframes. Timestamps must remain monotonic across item boundaries. If FFmpeg cannot preserve a seamless timeline, insert `#EXT-X-DISCONTINUITY` and publish the corresponding new initialization segment.
+**Segment duration rationale**: 2s lowers latency and keeps the window small (12 × 2s = 24s) while staying above the manifest TTL (1–2s). The 2s GOP (30fps, `-g 60`) already matches the target, so segments cut cleanly on keyframes. Longer (4–6s) raises latency and window depth; shorter than 2s inflates segment/request overhead and R2 Class B ops with little gain.
 
-Every segment name is globally unique and never reused, including after a restart or playlist loop. Use a run/session ID plus a monotonically increasing media sequence, for example:

-The local `data/hls/` directory is staging data and may be regenerated. Source media, playlist revisions, and schedule state are authoritative; generated HLS is not backed up as application state.
+**Run-scoped manifest URIs.** Segments and the init file are stored run-scoped under `hls/r-{runID}/…`, so the live `hls/playlist.m3u8` must reference them with that run prefix. Before the final commit step, the publisher rewrites each bare relative media URI (segments plus `#EXT-X-MAP:URI`) to `r-{runID}/<name>`. `publishManifest` in `backend/playout/src/playlist.go` does this via `rewriteManifestToRun`, using the same `runID` under which the segments were uploaded; the rewrite is skipped in slate mode (its manifest is served as-is). The published manifest therefore contains, e.g.:
+
+```m3u8
+#EXT-X-MAP:URI="r-20260807T170412Z/init.mp4"
+#EXTINF:2.000000,
+r-20260807T170412Z/seg-000001234.m4s
+```
+
+The `linearvoid-media` Worker on `media.linearvoid.tv` is a faithful path→R2 mapper and serves these run-scoped paths directly; it does **not** rewrite URIs at serve time.
+
+`data/hls/` is regenerable staging. Source media, playlist revisions, and schedule state are authoritative; generated HLS is not backed up as application state.

 Further rules:
 
-- Do not add query-string cache busters to segment URLs; uniqueness belongs in the path.
-- Cache keys must preserve hostname and full path. Ignore only explicitly approved tracking parameters.
-- HLS responses require `Access-Control-Allow-Origin: https://linearvoid.tv` (or the reviewed origin allowlist), `GET`, `HEAD`, and `OPTIONS` support, and correct MIME types.
-- Enable Smart Tiered Cache for `media.linearvoid.tv` to reduce R2 reads on regional misses.
-- Purge manifests when necessary, but never purge immutable segments during normal operation.
-- Retain expired-window segments in R2 for at least the maximum manifest TTL plus client retry/grace time. A practical minimum is one hour; lifecycle deletion may run later according to storage policy.

-
-# Check Cloudflare status
 curl -I https://linearvoid.tv/health

+**Common causes:** DNS misconfiguration (A record → wrong IP); Cloudflare proxy disabled (grey cloud exposes origin); SSL certificate expired (Cloudflare → SSL/TLS); Cloudflare outage ([cloudflarestatus.com](https://www.cloudflarestatus.com)).
 
-- DNS misconfiguration (A record pointing to wrong IP)
-- Cloudflare proxy disabled (grey cloud → origin exposed directly)
-- SSL certificate expired (check Cloudflare dashboard → SSL/TLS)
-- Cloudflare outage → check [https://www.cloudflarestatus.com](https://www.cloudflarestatus.com)
+**Mitigation:** Verify A record points `linearvoid.tv` → origin IP (proxied, orange cloud). Bypass Cloudflare temporarily:

+```
 
 ## 2. Origin Health (VPS/Docker)
 
-**Symptoms:** Cloudflare returns 502/504, containers down.
+**Symptoms:** Cloudflare 502/504, containers down.

-- Docker daemon stopped: `systemctl status docker`
-- Container restart loop: `docker ps -a --filter "status=exited"`
-- Resource exhaustion (OOM): `dmesg | grep -i oom`
+**Common causes:** Host disk full (`df -h`); Docker daemon stopped (`systemctl status docker`); container restart loop (`docker ps -a --filter "status=exited"`); OOM (`dmesg | grep -i oom`).
 
 **Mitigation:**
 
-- Restart stack: `docker compose -f docker-compose.prod.yml up -d`
-- Free disk: `docker system prune -f`
-- Check logs per service: `docker logs linearvoid-<service> --tail 100`

----
-
-### 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`.
+see [Prometheus Results](./prometheus_results.md#redis-metrics) for full output of all 100+ metric names exposed by the Redis exporter.

-# 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.

-| Item                    | What to adjust                                                                                                                                  |
-| ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
-| **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`.                              |
-
-Run the command for any target and you’ll receive a JSON payload like:
-
-```json
-{
-  "status": "success",
-  "data": [
-    "up",
-    "process_cpu_seconds_total",
-    "http_requests_total",
-    "... more metrics ..."
-  ]
-}
-```
-
-That array (`data`) is the complete list of metric names currently scraped from the specified endpoint.

-
-## Worker: `linearvoid` (edge cache headers)
-
-The Worker at `infrastructure/cloudflare/worker.js` runs on the `linearvoid` Workers service. It intercepts requests and adds immutable `Cache-Control` headers to `.m4s` segment files.
-
-Deploy via Wrangler CLI:
-
-```bash
-npx wrangler deploy infrastructure/cloudflare/worker.js
-```
-
-Or paste into the Workers dashboard at the URL above (Quick Edit).
-
-## Pages: Static frontend
-
-### Direct Upload via Gitea Actions
-
-Use `.gitea/workflows/pages-deploy.yml` to build in Gitea Actions and upload via the Cloudflare API.
-
-See [gitea-cloudflare-pages.md](./gitea-cloudflare-pages.md) for the workflow.
-
-### Variables and secrets
-
-On Cloudflare pages, set the following environment variables (needed to run the frontend)
-

+# Cloudflare Workers Setup — Linear Void
+
+Linear Void uses Cloudflare Workers for two purposes:
+
+| Product     | Purpose            | What                                                                                         |
+| ----------- | ------------------ | -------------------------------------------------------------------------------------------- |
+| **Workers** | Static SPA hosting | `linearvoid-frontend` (`frontend/wrangler.toml`) — Vite SPA (`frontend/dist`) static assets  |
+| **Workers** | Edge HLS delivery  | `linearvoid-media` (`infrastructure/cloudflare/`) — R2-bound Worker on `media.linearvoid.tv` |
+
+Both are managed under **Workers & Pages** in the Cloudflare dashboard.
+
+## Dashboard URLs

+
+## Worker: `linearvoid-media` (edge HLS delivery)
+
+The Worker in [`infrastructure/cloudflare/`](../../infrastructure/cloudflare/) runs on the `linearvoid-media` Workers service. It owns the `media.linearvoid.tv` host, serves HLS objects from the R2 bucket (bound as `MEDIA_BUCKET`), and stamps immutable `Cache-Control` on segments plus a short TTL on live manifests (CORS + Range supported). See its [README](../../infrastructure/cloudflare/README.md).
+
+**Run-scoped layout.** R2 objects are stored run-scoped (`hls/r-{runID}/seg-*.m4s`, `…/init.mp4`), and the live `hls/playlist.m3u8` references them with the run prefix (the playout rewrites bare URIs before publishing — see [`docs/STREAMING.md`](../STREAMING.md)). The Worker is a faithful path→R2 mapper: it serves whatever key the request path resolves to (e.g. `/hls/r-…/seg-*.m4s`), adds the cache headers by file type, and does not rewrite manifest URIs at serve time.
+
+Test / deploy:
+
+```bash
+cd infrastructure/cloudflare
+npm install && npm test              # unit + Miniflare R2 tests
+npx wrangler deploy                  # preview/test target
+npx wrangler deploy --env production # attach media.linearvoid.tv
+```
+
+Attach the production custom domain only after removing `media.linearvoid.tv` from the R2 bucket's direct custom-domain binding. Automated production deploy: [`.gitea/workflows/workers-media-deploy.yml`](../../.gitea/workflows/workers-media-deploy.yml).
+
+## Worker: static frontend
+
+Serve the Vite-built SPA (`frontend/dist`) as Worker static assets:
+
+1. Build the frontend: `cd frontend && npm run build`.
+2. Bind `frontend/dist` to the Worker as static assets (Workers Static Assets / `assets` in `wrangler.toml`).
+3. Attach the `linearvoid.tv` custom domain to the Worker.
+
+See [gitea-cloudflare-workers.md](./gitea-cloudflare-workers.md) for the automated deployment workflow.
+
+### Build-time variables
+
+The `VITE_PUBLIC_*` values are baked into the bundle at build time by Vite (`vite.config.ts` uses `envDir: ".."` to read them from the repo root). They are supplied by the Gitea Actions build environment from Gitea secrets — not as Worker runtime variables. The static-assets Worker has no runtime JavaScript, so it reads no `env` at request time.
+
+| Name                                     | Value                                           |

+| `VITE_PUBLIC_WS_URL`                     | `wss://linearvoid.tv/ws`                        |
+| `VITE_PUBLIC_HLS_URL`                    | `https://media.linearvoid.tv/hls/playlist.m3u8` |
+| `VITE_PUBLIC_ADMIN_DEFAULT_MODERATOR`    | `boogers`                                       |

+
+Backend services (playout, chat, nginx) read their own runtime variables (`ADMIN_*`, `HLS_*`, `PLAYLIST_PATH`, `R2_*`, `DATABASE_URL`, `REDIS_URL`) from the container environment — see [`.env.example`](../../.env.example).

-# 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: {}
-
-jobs:
-  deploy:
-    runs-on: ubuntu-latest
-    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.

+# Gitea to Cloudflare Workers — Linear Void
+
+## Goal
+
+Deploy the Linear Void frontend (Vite + TypeScript SPA) from Gitea to Cloudflare Workers using Gitea Actions and Wrangler.
+
+## Prerequisites
+
+1. **Cloudflare Worker** for the SPA:
+   - Dashboard → Workers & Pages → Create → Worker (or Workers Static Assets).
+   - Name it `linearvoid-frontend` (the edge-cache Worker already uses the `linearvoid` name).
+2. **API token** with Workers permissions:
+   - Create at <https://dash.cloudflare.com/profile/api-tokens>
+   - Permission: `Account → Workers Scripts → Edit` and `Account → Workers Routes → Edit`
+   - Store in Gitea → Settings → Secrets as `CLOUDFLARE_API_TOKEN`
+3. **Account ID** from Cloudflare dashboard overview → store as `CLOUDFLARE_ACCOUNT_ID`
+4. **Wrangler config** (`frontend/wrangler.toml`) binding the `frontend/dist` output as static assets.
+
+> **Naming:** Workers share a namespace under "Workers & Pages". The media edge Worker is `linearvoid-media` ([`infrastructure/cloudflare/`](../../infrastructure/cloudflare/wrangler.toml), deployed via `.gitea/workflows/workers-media-deploy.yml`) and the SPA Worker is `linearvoid-frontend` (`frontend/wrangler.toml`, deployed via `.gitea/workflows/workers-deploy.yml`).

+
+## Notes
+
+- The existing `ci.yml` already builds the frontend; the Workers deploy workflow is additive and independent.
+- Multi-page SPA (`vite.config.ts`) produces three entry points — Workers static assets serve them correctly.
+- For SPA fallback routing, set Workers static assets `not_found_handling` to `single-page-application` (serve `index.html` for unknown paths).
+- The deploy workflow lives in `.gitea/workflows/workers-deploy.yml` (triggered after CI succeeds).

+# linearvoid-media Worker
+
+Cloudflare Worker that owns **`media.linearvoid.tv`** and serves the HLS objects
+stored in the `linearvoid-media` R2 bucket, applying the edge cache policy in code:
+
+| Object                                      | Cache-Control                                    |
+| ------------------------------------------- | ------------------------------------------------ |
+| `.m4s` / `.ts` / `.mp4` / `.m4a` (segments) | `public, max-age=31536000, immutable`            |
+| `.m3u8` (live manifest)                     | `public, max-age=1, s-maxage=2, must-revalidate` |
+
+It also adds HLS CORS (`Access-Control-Allow-Origin: *`), OPTIONS preflight, a
+`/health` probe, and Range-request support. This worker replaces direct R2
+custom-domain serving on the media host so cache headers/CORS are controlled in
+code (cache rules on the same host remain the origin baseline).

+## Deploy
+
+**Preview / test target** (default environment → `*.workers.dev`):
+
+```bash
+cd infrastructure/cloudflare
+npx wrangler deploy
+```
+
+**Production** (attaches `media.linearvoid.tv` as a custom domain on this worker):
+
+```bash
+cd infrastructure/cloudflare
+npx wrangler deploy --env production
+```
+
+Both need `CLOUDFLARE_API_TOKEN` (Workers Scripts/Routes edit) and
+`CLOUDFLARE_ACCOUNT_ID` in the environment. The media host must first be removed
+from the R2 bucket's direct custom-domain binding, otherwise the route collides.
+
+Automated production deploys run via
+[`.gitea/workflows/workers-media-deploy.yml`](../../.gitea/workflows/workers-media-deploy.yml)
+after CI succeeds on `main`.
