+
+## 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.
 - 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.

-## Unreleased
+## [1.0.6] - 2026-08-05
 
 ### Added
 
-- Documentation for Admin UI Media Library (arc42 updates, refined TODO, media DB model decisions per ADR-006).
+- `GET /api/admin/chat-log` endpoint with `?room=`, `?limit=`, `?before=`, `?username=`, `?text=` filter/pagination support.
-- Started implementation of full Media CRUD + video duration extraction using ffprobe (Media Library - Full CRUD section).
+- `GET /api/admin/chat-log/:id` endpoint returning a single chat log entry as JSON.
-- Added `/api/admin/media/{id}` GET/PUT/DELETE handlers for media metadata retrieval, updates, and file+record deletion.
+- `DELETE /api/admin/chat-log/:id` endpoint returning 204 No Content on success.
-- Extended admin schedule and dashboard data endpoints with media duration totals, runtime strings, and media counts.
+- `DELETE /api/admin/chat-log/bulk` endpoint accepting `{"ids": [...]}` for bulk deletion (max 500).
-- Added admin UI runtime display for schedule/dashboard plus media library edit/delete actions.
+- Chat Log admin tab with table, individual delete with confirmation dialog, pagination (prev/next), search/filter by room/username/text, select-all checkbox, and bulk delete button.
-- Added a dedicated plain TypeScript admin module for tab navigation, media CRUD actions, schedule/system analytics refresh, and moderation workflows without Alpine dependencies.
+- Added `"lint": "tsc --noEmit"` script to `frontend/package.json`.
-- Added resumable chunked admin media upload flow with upload-session endpoints and client progress indicators.
+- `/api/admin/media/{id}` GET/PUT/DELETE handlers for media metadata retrieval, updates, and file+record deletion.
-- Expanded architecture documentation with scaling strategy, API surface reference, detailed video normalization spec, and Cloudflare configuration reference.
+- Resumable chunked admin media upload flow with upload-session endpoints and client progress indicators.
-- Added `API.md`, `DEPLOYMENT.md`, `MONITORING.md`, and `SECURITY.md` as dedicated operational documentation guides.
+- Prometheus-format `/metrics` endpoint for chat runtime and admin-session monitoring.
+- Dedicated operational documentation: `API.md`, `DEPLOYMENT.md`, `MONITORING.md`, `SECURITY.md`.
 
 ### Changed
 
-- Revised ADR-006 to reflect current implemented storage: PostgreSQL is the compose default and deployed primary backend, with SQLite retained as optional fallback.
+- Split `frontend/admin/index.html` into a template shell plus 9 per-tab page HTML files loaded dynamically via `loadPageContent` / `switchTab` / `bindPageEvents`.
-- Updated chat runtime image to include ffmpeg/ffprobe for media duration probing on upload.
 - Rebuilt viewer, admin, and admin-login pages around custom semantic class structures with accessibility-focused landmarks, tab semantics, and keyboard-focus behavior.
 - Replaced legacy and Tailwind-based stylesheet rules with a custom design-token CSS system covering responsive layouts, forms, tables, and reduced-motion behavior.
-- Switched the frontend theme to dark-mode-first token defaults with a light-scheme override path for users who prefer light appearance.
+- Switched frontend theme to dark-mode-first token defaults with light-scheme override.
-- Refactored the viewer page to a single header plus unified content layout with responsive video/chat split, mobile stacking, and chat panel toggle behavior.
+- Applied new color palette (`#32292f` dark, `#b4c4ae` light, `#587792` brand, `#2ebfa5` focus, `#04650d` ok) across all 22 CSS custom properties in dark and light themes.
-- Code-split `hls.js` via lazy loading in the viewer bootstrap to shrink the main frontend bundle and isolate stream playback logic into a dedicated chunk.
+- Replaced hardcoded admin sidebar and tab-trigger colors with CSS custom properties.
-- Added navigation links in root README and architecture docs to the new API, deployment, monitoring, and security guide files.
+- Optimized CI pipeline: removed duplicate `docker compose build --no-cache` from test job, removed broken playlist validation step, fixed Go module cache path, added Docker Buildx registry cache to docker/release jobs.
+- Bumped chat healthcheck `start_period` from 10s to 30s in `docker-compose.prod.yml`.
+- CD workflow now verifies nginx (port 8080) + chat (3000) + playout (8081); dumps container logs for all failing services.
+- Updated Prometheus scrape targets and Grafana dashboard queries to use live chat metrics.
 
 ### Fixed
 
-- Started Admin UI Media Library backend implementation by adding the `Media` GORM model and AutoMigrate integration in chat startup.
+- Go module cache in CI now correctly references only `backend/chat/go.sum` (playout go.sum did not exist); added `go mod download` step to seed cache.
-- Implemented media upload duration probing with ffprobe and persisted media metadata to the database alongside filesystem storage.
+- Removed broken playlist validation step (`go run src/playlist.go` without go.mod) from CI test job.
-- Updated media listing to read from the media table and return duration metadata with HH:MM:SS runtime formatting.
+- Converted nginx CI build from custom shell `docker buildx` to `docker/build-push-action@v5` for cache consistency.
-- Removed Tailwind and Alpine runtime/build dependencies from the frontend package configuration and eliminated Tailwind directives/warnings during production build.
 - Enforced 2GB upload ceiling plus server-side media file type/size validation for admin uploads.
-- Increased nginx `client_max_body_size` to allow resumable admin upload chunks and prevent `413 Content Too Large` responses.
+- Increased nginx `client_max_body_size` to allow resumable admin upload chunks without 413 errors.
-- Removed legacy now-playing viewer UI elements that conflicted with the streamlined single-header layout.
+- Removed unused `data-admin-*` Vite env var attributes from admin HTML template.
+- Removed Tailwind and Alpine runtime/build dependencies; eliminated Tailwind directives/warnings during production build.

+## Versioning and Releases
+
+### Version Scheme
+
+Linear Void follows **Semantic Versioning** ([SemVer](https://semver.org)): `MAJOR.MINOR.PATCH`.
+
+- **MAJOR** — breaking changes to the viewer, API, or deployment model.
+- **MINOR** — new features (endpoints, admin tabs, UI capabilities) that are backward-compatible.
+- **PATCH** — bug fixes, optimizations, documentation polish.
+
+Git tags use a `v` prefix: `1.0.2`, `1.1.0`, `v2.0.0`.
+
+### Where Versions Are Declared
+
+| File                           | Token          | Example                   |
+| ------------------------------ | -------------- | ------------------------- |

+| Push to `main`      | `ci.yml` → `cd.yml` | CI builds + pushes images with `main`/`latest` tags, CD deploys to production                                      |
+
+### Full Release Procedure
+
+#### Step 1: Bump version numbers
+
+Update these files to the new version (replace `X.Y.Z`):
+
+- [frontend/package.json](frontend/package.json)
+- [CHANGELOG.md](CHANGELOG.md) — add new section at top
+- [README.md](README.md) — version badge
+
+```bash
+# frontend/package.json
+"version": "X.Y.Z"
+
+# CHANGELOG.md — add new section at top
+## [X.Y.Z] - YYYY-MM-DD
+
+# README.md — version badge
+version-X.Y.Z-blue
+```
+
+#### Step 2: Write changelog
+
+Add entries under `## [X.Y.Z]` in `CHANGELOG.md` following [Keep a Changelog](https://keepachangelog.com) format (`Added`, `Changed`, `Fixed`, `Removed`).
+
+#### Step 3: Commit and tag
+
+```bash
+# Stage all version bumps + changelog
+git add frontend/package.json CHANGELOG.md README.md .github/instructions/TODO.md
+
+# Commit
+git commit -m "chore: bump version to X.Y.Z"
+
+# Create annotated tag
+git tag -a X.Y.Z -m "Release X.Y.Z"
+
+# Push commit and tag
+git push origin main
+git push origin X.Y.Z
+```
+
+#### Step 4: Verify CI/CD
+
+- CI workflow (`ci.yml`) runs on push to `main` → builds & pushes `main`/`latest` images.
+- Release workflow (`release.yml`) triggers on `X.Y.Z` tag → builds images with semver tags (`X.Y.Z`, `X.Y`, `latest`), creates Gitea Release.
+- CD workflow (`cd.yml`) triggers after CI completes → deploys to production.
+
+Monitor at: [git.allucanget.biz/zwitschi/linearvoid/actions](https://git.allucanget.biz/zwitschi/linearvoid/actions)
+
+#### Step 5: Verify release
+
+Check the Gitea Releases page for the new tag:
+[git.allucanget.biz/zwitschi/linearvoid/releases](https://git.allucanget.biz/zwitschi/linearvoid/releases)
+
+### Manual Release (workflow_dispatch)
+
+If a tag push fails or a re-release is needed:
+
+1. Go to [Actions → Release workflow](https://git.allucanget.biz/zwitschi/linearvoid/actions?workflow=release.yml)
+2. Click "Run workflow"
+3. Enter version (e.g. `1.0.2`)
+4. The workflow builds images, pushes semver tags, and creates the Gitea Release
+
+### Docker Image Tags
+
+Every release produces these tags in the Gitea Container Registry:
+
+| Image     | Tags                     |
+| --------- | ------------------------ |
+| `playout` | `X.Y.Z`, `X.Y`, `latest` |
+| `chat`    | `X.Y.Z`, `X.Y`, `latest` |
+| `nginx`   | `X.Y.Z`, `X.Y`, `latest` |
+
+Example for `1.0.2`:
+
+```text
+git.allucanget.biz/zwitschi/linearvoid/chat:1.0.2
+git.allucanget.biz/zwitschi/linearvoid/chat:1.0
+git.allucanget.biz/zwitschi/linearvoid/chat:latest
+git.allucanget.biz/zwitschi/linearvoid/playout:1.0.2
+git.allucanget.biz/zwitschi/linearvoid/playout:1.0
+git.allucanget.biz/zwitschi/linearvoid/playout:latest
+```
+
+### Moving Completed Tasks
+
+After release, move completed sections from `TODO.md` to `DONE.md` and update `CHANGELOG.md` if needed. The `DONE.md` file serves as the historical record linking tasks to releases.
