Next priority is implementation of the Playout Service. +**Full Backend and Frontend Implementation Complete** -## [2026-08-02] - Architecture Foundation +- **Playout Service** (`backend/playout/`): Go-based playlist management, ffprobe normalization validation, continuous HLS with immutable segment naming, automatic R2 sync, health check endpoint, and Docker integration (ADR-001, ADR-003). +- **Chat Backend** (`backend/chat/`): Go + Gorilla WebSocket, Redis for presence/rate limiting/pub/sub, SQLite persistence for message history and ModerationLog (ADR-006/ADR-007), public rooms, private DM routing, moderation commands with immutable audit logging, health check endpoint, and docker-compose integration. +- **Frontend** (`frontend/`): Vite + TypeScript + Tailwind + Alpine.js, HLS player with hls.js, chat sidebar with room switching and private messaging, "Now Playing" overlay, and modern UI (ADR-002, ADR-003). +- Complete `docker-compose.yml` for local development with all services, volumes, and healthchecks. +- All ADRs (001-007) created and linked in documentation. +- `TODO.md`, `DONE.md`, and `CHANGELOG.md` updated with full traceability. +- Git repository initialized with comprehensive initial commit. -- Project structure and architecture documentation finalized (arc42 template fully populated, ADRs for overall design, module structure, and tech stack). -- Consolidated ADR-001 (merged all previous drafts). -- Created ADR-002 (module/folder structure) and ADR-003 (tech stack, languages, Docker-first, implicit assumptions). -- Updated root README.md and `docs/architecture/README.md` with diagrams, quality goals, deployment view, and cross-references. +The project is a fully functional, self-hosted 24/7 linear video channel with synchronized playback, custom chat, R2 delivery, moderation, and admin-ready structure.
