+# API Reference
+
+This document describes the currently implemented API surfaces in Linear Void.
+
+## Base URLs
+
+- Public app and admin: <https://linearvoid.tv>
+- WebSocket endpoint: <wss://linearvoid.tv/ws>
+- Local fallback: <http://localhost> and <ws://localhost/ws>
+
+## Authentication Model
+
+Admin REST endpoints use a cookie session.
+
+- Cookie name: linearvoid_admin_session
+- Cookie attributes: HttpOnly, SameSite=Strict, Secure when request is HTTPS (or X-Forwarded-Proto=https)
+- Session TTL: controlled by ADMIN_SESSION_TTL_HOURS (default 12h)
+
+## Chat WebSocket API
+
+### Connect
+
+Endpoint:
+
+- GET /ws?username={name}&room={room}
+
+Client sends JSON messages over the socket.
+
+### Message Envelope (client -> server)
+
+```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.
+
+### Message Envelope (server -> client)
+
+```json

+# Production Deployment Guide
+
+This guide describes a production-style deployment for Linear Void using Docker Compose, Gitea registry images, and Cloudflare fronting.
+
+## Target Topology
+
+- Host: Linux server with Docker Engine
+- Reverse proxy: nginx container (linearvoid-nginx)
+- Core services: playout, chat, redis, postgres
+- Observability: prometheus, grafana
+- CDN/edge: Cloudflare
+
+## Prerequisites
+
+- Docker Engine + Docker Compose plugin
+- Network access to git.allucanget.biz
+- A valid .env file with production values
+- DNS configured for linearvoid.tv (and media.linearvoid.tv if split media domain is used)
+
+## Environment File
+
+Use .env with at least:
+
+- CI_REGISTRY_URL
+- CI_REGISTRY_NAMESPACE
+- CHAT_PORT
+- NGINX_PORT
+- DATABASE_URL (if overridden)
+- REDIS_URL (if overridden)
+- ADMIN_USERNAME
+- ADMIN_PASSWORD
+- VITE_PUBLIC_APP_URL
+- VITE_PUBLIC_WS_URL
+- VITE_PUBLIC_HLS_URL
+- Cloudflare/R2 variables when media sync is enabled
+
+See .env.example and SETUP.md for full variable reference.
+
+## Pull-and-Run Deployment
+
+From repository root:
+
+```bash
+docker login git.allucanget.biz
+
+docker compose -f docker-compose.prod.yml pull
+docker compose -f docker-compose.prod.yml up -d --remove-orphans
+```
+
+## First-Time or Recovery Provisioning
+
+1. Ensure host paths exist:
+
+```bash
+mkdir -p data/chat data/playlist data/media data/hls
+```
+
+1. Confirm volumes and networks:
+
+```bash
+docker volume ls
+docker network ls
+```
+
+1. Start stack:
+
+```bash
+docker compose -f docker-compose.prod.yml up -d
+```
+
+## Health Verification
+
+After startup, check service status:
+
+```bash
+docker compose -f docker-compose.prod.yml ps
+```
+
+Endpoint checks:
+
+- App: <http://{host}:8080/>
+- Nginx health: <http://{host}:8080/health>
+- Chat health: <http://{host}:3000/health>
+- Playout health: <http://{host}:8081/health>
+- Prometheus: <http://{host}:9090>
+- Grafana: <http://{host}:3001>
+
+Domain checks:
+
+- <https://linearvoid.tv>
+- <https://linearvoid.tv/admin>
+- <https://linearvoid.tv/metrics>
+
+## Zero/Low-Downtime Update Pattern
+
+1. Pull newest images.
+1. Recreate changed services only:
+
+```bash
+docker compose -f docker-compose.prod.yml pull
+
+docker compose -f docker-compose.prod.yml up -d nginx chat playout
+```
+
+1. Re-run health checks.
+
+## Rollback
+
+If new images are unhealthy:
+
+1. Pin previous tags in docker-compose.prod.yml.
+2. Pull pinned tags.
+3. Restart impacted services.
+
+```bash
+docker compose -f docker-compose.prod.yml pull
+
+docker compose -f docker-compose.prod.yml up -d nginx chat playout
+```
+
+## Operational Tasks
+
+### View logs
+
+```bash
+docker compose -f docker-compose.prod.yml logs -f nginx chat playout
+```
+
+### Restart one service
+
+```bash
+docker compose -f docker-compose.prod.yml restart chat
+```
+
+### Stop stack
+
+```bash
+docker compose -f docker-compose.prod.yml down
+```
+
+### Keep volumes (recommended) vs remove volumes (destructive)
+
+```bash
+# keep data
+docker compose -f docker-compose.prod.yml down
+
+# destructive (remove data)
+docker compose -f docker-compose.prod.yml down -v
+```
+
+## Nginx and Proxy Considerations
+
+- If an external proxy (for example Nginx Proxy Manager) fronts the stack, align request body limits with internal nginx.
+- For resumable admin uploads, ensure client_max_body_size supports chunk requests in both proxy layers.
+
+## Security Baseline
+
+- Use strong ADMIN_PASSWORD and rotate regularly.
+- Keep Docker host access restricted.
+- Prefer HTTPS/WSS through Cloudflare.
+- Restrict exposed ports if only proxy access is needed.
+
+## Common Deployment Pitfalls
+
+- Missing frontend build artifacts in local-only compose workflows.
+- Wrong registry credentials or missing login.
+- Misaligned domain env vars (app/ws/hls) causing mixed-origin errors.
+- Proxy-layer body size limits returning 413 on upload.
+- Health checks failing before service warmup is complete.

+# Monitoring Guide
+
+This guide covers Prometheus and Grafana setup for Linear Void.
+
+## Current Monitoring Components
+
+- Prometheus container: linearvoid-prometheus
+- Grafana container: linearvoid-grafana
+- Metrics target: chat service /metrics
+- Base scrape config: monitoring/prometheus/prometheus.yml
+
+## Prometheus Configuration
+
+Current scrape config:
+
+- Job chat -> chat:3000
+- Job prometheus -> prometheus:9090
+- Global scrape interval: 15s
+
+File:
+
+- monitoring/prometheus/prometheus.yml
+
+## Start Monitoring Stack
+
+With compose stack up:
+
+- Prometheus UI: <http://localhost:9090>
+- Grafana UI: <http://localhost:3001>
+
+Compose services include prometheus and grafana in both docker-compose.yml and docker-compose.prod.yml.
+
+## Grafana Provisioning
+
+Current mount paths:
+
+- Dashboards directory: monitoring/grafana/dashboards
+- Datasources directory: monitoring/grafana/datasources
+
+Notes:
+
+- The dashboards directory includes a Prometheus overview dashboard file.
+- Datasource provisioning can be done with a YAML file in monitoring/grafana/datasources, or by configuring a datasource in Grafana UI.
+
+Example datasource provisioning file (create if needed):
+
+```yaml
+apiVersion: 1
+
+datasources:
+  - name: Prometheus
+    type: prometheus
+    access: proxy
+  url: http://prometheus:9090
+    isDefault: true
+```
+
+## Dashboard References
+
+- Provisioned dashboard: [monitoring/grafana/dashboards/dashboard.json](monitoring/grafana/dashboards/dashboard.json)
+- Root dashboard snapshot: [monitoring/grafana/dashboard.json](monitoring/grafana/dashboard.json)
+
+Grafana screenshot:
+
+![Grafana dashboard screenshot](docs/img/grafana-screenshot.png)
+
+## Key Metrics to Track
+
+### Chat/Application
+
+- linearvoid_chat_connected_clients
+- linearvoid_chat_stored_messages_total
+- linearvoid_chat_moderation_actions_total
+- linearvoid_chat_redis_enabled
+- linearvoid_chat_redis_up
+- linearvoid_chat_active_admin_sessions
+
+### Prometheus Runtime
+
+- up
+- process_cpu_seconds_total
+- process_resident_memory_bytes
+- prometheus_tsdb_head_series
+- prometheus_tsdb_wal_writes_failed_total
+- prometheus_tsdb_compactions_failed_total
+
+## Suggested Alerts
+
+Create a Prometheus rules file (for example monitoring/prometheus/alerts.yml) and wire it into Prometheus.
+
+Recommended baseline alerts:
+
+- Chat target down for 2m
+- Prometheus target down for 2m
+- Redis indicator down for 2m
+- TSDB WAL/compaction failure rate above zero
+- Elevated handler/query latency p99
+
+## Validate Monitoring End-to-End
+
+1. Verify /metrics through nginx:
+
+- <https://linearvoid.tv/metrics>
+
+1. Confirm targets in Prometheus:
+
+- Status -> Targets page in Prometheus UI
+
+1. Confirm dashboard data in Grafana:
+
+- Import or open provisioned dashboards
+
+## Troubleshooting
+
+### No chat metrics in Prometheus
+
+- Check chat container health and logs.
+- Confirm /metrics is reachable from Prometheus container.
+- Verify scrape target is chat:3000 in prometheus.yml.
+
+### Grafana shows no data
+
+- Ensure datasource points to <http://prometheus:9090>.
+- Confirm Prometheus is healthy.
+- Check dashboard query labels match active jobs.
+
+### High cardinality or query slowness
+
+- Reduce unneeded labels.
+- Limit expensive dashboard 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.

+# Security Guide
+
+This document summarizes security controls and best practices for Linear Void.
+
+## Security Model Overview
+
+Security is layered across:
+
+- Cloudflare edge
+- nginx reverse proxy
+- chat/admin backend
+- container and host operations
+
+## Authentication and Sessions
+
+Admin access is session-cookie based.
+
+- Login endpoint: /api/admin/login
+- Session endpoint: /api/admin/session
+- Logout endpoint: /api/admin/logout
+- Cookie: linearvoid_admin_session
+- Cookie flags: HttpOnly, SameSite=Strict, Secure over HTTPS
+- Session expiry enforced server-side
+
+Best practices:
+
+- Set strong ADMIN_USERNAME and ADMIN_PASSWORD values.
+- Rotate admin credentials periodically.
+- Keep ADMIN_SESSION_TTL_HOURS aligned with operational policy.
+
+## Transport Security
+
+- Enforce HTTPS for app/admin endpoints.
+- Use WSS for chat WebSocket.
+- Keep Cloudflare TLS mode strict and valid at origin.
+
+## Reverse Proxy Controls
+
+nginx controls include:
+
+- auth_request guard for /admin and /api/admin paths
+- dedicated unauthorized behavior for admin API responses
+- explicit websocket upgrade headers for /ws
+- upload body-size limits for resumable media chunk uploads
+
+Best practices:
+
+- Keep proxy body-size and timeout settings aligned across all proxy layers.
+- Avoid exposing backend service ports publicly unless required.
+
+## Input Validation and Upload Safety
+
+Server-side protections include:
+
+- extension allow-list for media uploads
+- MIME checks
+- file-size ceiling (2GB)
+- resumable chunk bounds and chunk-index validation
+- media path safety checks on delete
+
+Best practices:
+
+- Keep upload chunk size bounded.
+- Reject unsupported content types consistently.
+- Monitor 4xx/5xx rates on upload routes.
+
+## Rate Limiting and Abuse Controls
+
+- Chat rate limiting uses Redis INCR + EXPIRE windows.
+- Current baseline: more than 10 messages in 10 seconds is throttled.
+- Moderation actions are logged for auditability.
+
+Best practices:
+
+- Tune thresholds by observed abuse patterns.
+- Keep moderation logs reviewed and retained per policy.
+
+## Infrastructure and Secrets
+
+- Store secrets in .env (not in committed source).
+- Use Gitea Actions secrets for CI/CD credentials and admin credentials.
+- Restrict Docker host control plane exposure.
+- Limit who can read deployment environment files.
+
+## Cloudflare and Edge Security
+
+Recommended baseline:
+
+- WAF enabled
+- Rate limits on sensitive paths
+- Bot protection where appropriate
+- Cache rules scoped carefully to avoid caching private/control-plane content
+
+## Data Protection and Retention
+
+- Persistent data: postgres, redis append-only, chat state, playlist/media metadata
+- Backup and restore drills should be periodic
+- Restore procedures should be tested in isolated environments
+
+## Logging and Monitoring for Security
+
+Track and alert on:
+
+- repeated failed admin login attempts
+- spikes in 401 and 403 responses
+- sudden upload errors (413/400/500 patterns)
+- unusual websocket disconnect or message-rate anomalies
+
+## Hardening Checklist
+
+- [ ] HTTPS/WSS enforced end-to-end
+- [ ] Strong admin credentials configured
+- [ ] Secrets only in env/secrets stores
+- [ ] Proxy auth and websocket headers validated
+- [ ] Upload limits and validation active
+- [ ] Rate limiting active and tested
+- [ ] Cloudflare WAF/rate-limit rules active
+- [ ] Backup/restore drills completed
+- [ ] Security-related monitoring alerts routed
+
+## Incident Response Baseline
+
+1. Detect issue (alerts/logs/user reports).
+2. Triage scope (edge, proxy, app, data plane).
+3. Contain impact (rate limit, credential rotate, route disable).
+4. Recover services and verify health.
+5. Record timeline and corrective actions.
