Schema additions for issues #37-41:

New models:
- Domain (#37): Life domains (work, marriage, homelab, etc.)
- Idea (#38): Brain dumps with pgvector embeddings
- Relationship (#39): Generic entity linking (blocks, depends_on)
- Agent (#40): ClawdBot agent tracking with metrics
- AgentSession (#40): Conversation session tracking
- WidgetDefinition (#41): HUD widget registry
- UserLayout (#41): Per-user dashboard configuration

Updated models:
- Task, Event, Project: Added domainId foreign key
- User, Workspace: Added new relations

New enums:
- IdeaStatus: CAPTURED, PROCESSING, ACTIONABLE, ARCHIVED, DISCARDED
- RelationshipType: BLOCKS, BLOCKED_BY, DEPENDS_ON, etc.
- AgentStatus: IDLE, WORKING, WAITING, ERROR, TERMINATED
- EntityType: Added IDEA, DOMAIN

+# Docker Configuration
+
+Configuration guide specific to Docker Compose deployments.
+
+## Overview
+
+Docker Compose deployments use environment variables to configure all services. This guide covers Docker-specific configuration options.
+
+## Environment File
+
+All Docker configurations are in `.env` at the project root:
+
+```bash
+cp .env.example .env
+nano .env
+```
+
+## Service Configuration
+
+### Application Ports
+
+```bash
+# API port (external mapping)
+API_PORT=3001
+API_HOST=0.0.0.0
+
+# Web port (external mapping)
+WEB_PORT=3000
+
+# Public API URL (for Next.js client)
+NEXT_PUBLIC_API_URL=http://localhost:3001
+```
+
+### PostgreSQL Database
+
+```bash
+# Connection string for API (uses Docker internal networking)
+DATABASE_URL=postgresql://mosaic:mosaic_dev_password@postgres:5432/mosaic
+
+# PostgreSQL container configuration
+POSTGRES_USER=mosaic
+POSTGRES_PASSWORD=mosaic_dev_password
+POSTGRES_DB=mosaic
+POSTGRES_PORT=5432
+
+# Performance tuning (optional)
+POSTGRES_SHARED_BUFFERS=256MB
+POSTGRES_EFFECTIVE_CACHE_SIZE=1GB
+POSTGRES_MAX_CONNECTIONS=100
+```
+
+**Important:** For Docker deployments, use `postgres` as the hostname (container name), not `localhost`.
+
+### Valkey Cache
+
+```bash
+# Connection string for API (uses Docker internal networking)
+VALKEY_URL=redis://valkey:6379
+
+# Valkey container configuration
+VALKEY_PORT=6379
+VALKEY_MAXMEMORY=256mb
+```
+
+**Important:** For Docker deployments, use `valkey` as the hostname (container name), not `localhost`.
+
+### Authentik OIDC (Optional)
+
+When using the bundled Authentik service:
+
+```bash
+# Authentik PostgreSQL
+AUTHENTIK_POSTGRES_USER=authentik
+AUTHENTIK_POSTGRES_PASSWORD=authentik_password
+AUTHENTIK_POSTGRES_DB=authentik
+
+# Authentik Server Configuration
+AUTHENTIK_SECRET_KEY=change-this-to-a-random-secret-key-minimum-50-characters
+AUTHENTIK_ERROR_REPORTING=false
+AUTHENTIK_BOOTSTRAP_PASSWORD=admin
+AUTHENTIK_BOOTSTRAP_EMAIL=admin@localhost
+AUTHENTIK_COOKIE_DOMAIN=.localhost
+
+# Authentik Ports
+AUTHENTIK_PORT_HTTP=9000
+AUTHENTIK_PORT_HTTPS=9443
+
+# OIDC Configuration (configured in Authentik UI)
+OIDC_ISSUER=http://localhost:9000/application/o/mosaic-stack/
+OIDC_CLIENT_ID=your-client-id-here
+OIDC_CLIENT_SECRET=your-client-secret-here
+OIDC_REDIRECT_URI=http://localhost:3001/auth/callback
+```
+
+**Bootstrap Credentials:**
+- Username: `akadmin`
+- Password: Value of `AUTHENTIK_BOOTSTRAP_PASSWORD`
+
+### Ollama AI Service (Optional)
+
+When using the bundled Ollama service:
+
+```bash
+# Ollama endpoint (uses Docker internal networking)
+OLLAMA_ENDPOINT=http://ollama:11434
+
+# Ollama port (external mapping)
+OLLAMA_PORT=11434
+```
+
+## Docker Compose Profiles
+
+Control which optional services are started using profiles:
+
+```bash
+# Option 1: Command line
+docker compose --profile authentik up -d
+docker compose --profile ollama up -d
+docker compose --profile full up -d
+
+# Option 2: Environment variable
+COMPOSE_PROFILES=authentik,ollama  # Enable specific services
+COMPOSE_PROFILES=full              # Enable all optional services
+```
+
+Available profiles:
+- `authentik` - Authentik OIDC provider stack
+- `ollama` - Ollama LLM service
+- `full` - All optional services
+
+## Security Configuration
+
+### Production Secrets
+
+**CRITICAL:** Change these in production:
+
+```bash
+# PostgreSQL
+POSTGRES_PASSWORD=$(openssl rand -base64 32)
+
+# Authentik
+AUTHENTIK_SECRET_KEY=$(openssl rand -base64 50)
+AUTHENTIK_POSTGRES_PASSWORD=$(openssl rand -base64 32)
+AUTHENTIK_BOOTSTRAP_PASSWORD=$(openssl rand -base64 16)
+
+# JWT
+JWT_SECRET=$(openssl rand -base64 32)
+```
+
+### Network Security
+
+The Docker setup uses two networks:
+
+1. **mosaic-internal** (internal only)
+   - PostgreSQL
+   - Valkey
+   - Authentik PostgreSQL
+   - Authentik Redis
+   - No external access
+
+2. **mosaic-public** (external access)
+   - API
+   - Web
+   - Authentik Server
+   - Accessible from host
+
+## Volume Management
+
+### Persistent Volumes
+
+Data is stored in named Docker volumes:
+
+```bash
+# List volumes
+docker volume ls | grep mosaic
+
+# Inspect volume
+docker volume inspect mosaic-postgres-data
+
+# Backup volume
+docker run --rm \
+  -v mosaic-postgres-data:/data \
+  -v $(pwd):/backup \
+  alpine tar czf /backup/postgres-backup.tar.gz /data
+
+# Restore volume
+docker run --rm \
+  -v mosaic-postgres-data:/data \
+  -v $(pwd):/backup \
+  alpine tar xzf /backup/postgres-backup.tar.gz -C /
+```
+
+### Volume Locations
+
+- `mosaic-postgres-data` - PostgreSQL database files
+- `mosaic-valkey-data` - Valkey persistence
+- `mosaic-authentik-postgres-data` - Authentik database
+- `mosaic-authentik-redis-data` - Authentik cache
+- `mosaic-authentik-media` - Authentik uploaded files
+- `mosaic-authentik-certs` - Authentik certificates
+- `mosaic-authentik-templates` - Authentik email templates
+- `mosaic-ollama-data` - Ollama models
+
+## Custom Configurations
+
+### Using External Services
+
+Create `docker-compose.override.yml` to use external services:
+
+```yaml
+# Disable bundled PostgreSQL, use external
+services:
+  postgres:
+    profiles:
+      - disabled
+
+  api:
+    environment:
+      DATABASE_URL: postgresql://user:pass@external-db.example.com:5432/mosaic
+```
+
+See `docker-compose.override.yml.example` for more examples.
+
+### Development Overrides
+
+```yaml
+# docker-compose.override.yml
+services:
+  postgres:
+    command:
+      - "postgres"
+      - "-c"
+      - "log_statement=all"
+      - "-c"
+      - "log_duration=on"
+    ports:
+      - "5432:5432"
+
+  api:
+    environment:
+      LOG_LEVEL: debug
+    volumes:
+      - ./apps/api/src:/app/apps/api/src:ro
+```
+
+### Production Overrides
+
+```yaml
+# docker-compose.prod.yml
+services:
+  api:
+    restart: always
+    environment:
+      NODE_ENV: production
+      LOG_LEVEL: warn
+    deploy:
+      replicas: 2
+      resources:
+        limits:
+          cpus: '1.0'
+          memory: 1G
+
+  web:
+    restart: always
+    environment:
+      NODE_ENV: production
+    deploy:
+      replicas: 2
+      resources:
+        limits:
+          cpus: '0.5'
+          memory: 512M
+```
+
+Deploy:
+```bash
+docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+```
+
+## Resource Limits
+
+### Memory Limits
+
+Adjust based on your system:
+
+```yaml
+# docker-compose.override.yml
+services:
+  postgres:
+    deploy:
+      resources:
+        limits:
+          memory: 2G
+        reservations:
+          memory: 512M
+
+  api:
+    deploy:
+      resources:
+        limits:
+          memory: 1G
+        reservations:
+          memory: 256M
+```
+
+### CPU Limits
+
+```yaml
+services:
+  api:
+    deploy:
+      resources:
+        limits:
+          cpus: '1.0'
+        reservations:
+          cpus: '0.25'
+```
+
+## Health Checks
+
+All services include health checks. Adjust timing if needed:
+
+```yaml
+# docker-compose.override.yml
+services:
+  postgres:
+    healthcheck:
+      interval: 30s      # Check every 30s
+      timeout: 10s       # Timeout after 10s
+      retries: 5         # Retry 5 times
+      start_period: 60s  # Wait 60s before first check
+```
+
+## Logging Configuration
+
+### Log Drivers
+
+```yaml
+# docker-compose.override.yml
+services:
+  api:
+    logging:
+      driver: "json-file"
+      options:
+        max-size: "10m"
+        max-file: "3"
+```
+
+### Centralized Logging
+
+For production, consider:
+- Loki + Grafana
+- ELK Stack (Elasticsearch, Logstash, Kibana)
+- Fluentd
+- CloudWatch Logs
+
+Example with Loki:
+
+```yaml
+services:
+  api:
+    logging:
+      driver: loki
+      options:
+        loki-url: "http://loki:3100/loki/api/v1/push"
+        labels: "service=mosaic-api"
+```
+
+## Troubleshooting
+
+### Container Won't Start
+
+Check logs:
+```bash
+docker compose logs <service>
+```
+
+Common issues:
+- Port conflict: Change port in `.env`
+- Missing environment variable: Check `.env` file
+- Health check failing: Increase `start_period`
+
+### Network Issues
+
+Test connectivity between containers:
+```bash
+# From API container to PostgreSQL
+docker compose exec api sh
+nc -zv postgres 5432
+```
+
+### Volume Permission Issues
+
+Fix permissions:
+```bash
+# PostgreSQL volume
+docker compose exec postgres chown -R postgres:postgres /var/lib/postgresql/data
+```
+
+### Out of Disk Space
+
+Clean up:
+```bash
+# Remove unused containers, networks, images
+docker system prune -a
+
+# Remove unused volumes (WARNING: deletes data)
+docker volume prune
+```
+
+## Monitoring
+
+### Resource Usage
+
+```bash
+# Real-time stats
+docker stats
+
+# Specific container
+docker stats mosaic-api
+```
+
+### Health Status
+
+```bash
+# Check health of all services
+docker compose ps
+
+# JSON output
+docker compose ps --format json
+```

+```bash
+# Core services only (PostgreSQL, Valkey, API, Web)
+docker compose up -d
+
+# With Authentik OIDC
+docker compose --profile authentik up -d
+
+# With Ollama AI
+docker compose --profile ollama up -d
+
+# All services
+docker compose --profile full up -d
+
+# Or use Makefile
+make docker-up        # Core services
+make docker-up-full   # All services
+```
+
+## Stopping Services
+
+```bash
+# Stop (keeps data)
+docker compose down
+
+# Stop and remove volumes (deletes data!)
+docker compose down -v
+```
+
+## Viewing Status
+
+```bash
+# List running services
+docker compose ps
+
+# View logs (all services)
+docker compose logs -f
+
+# View logs (specific service)
+docker compose logs -f api
+
+# Last 100 lines
+docker compose logs --tail=100 api
+
+# Resource usage
+docker stats
+```
+
+## Service Management
+
+```bash
+# Restart all services
+docker compose restart
+
+# Restart specific service
+docker compose restart api
+
+# Rebuild and restart
+docker compose up -d --build
+
+# Pull latest images
+docker compose pull
+```
+
+## Database Operations
+
+```bash
+# PostgreSQL shell
+docker compose exec postgres psql -U mosaic -d mosaic
+
+# Run migrations
+docker compose exec api pnpm prisma:migrate:prod
+
+# Seed data
+docker compose exec api pnpm prisma:seed
+
+# Backup database
+docker compose exec postgres pg_dump -U mosaic mosaic > backup.sql
+
+# Restore database
+cat backup.sql | docker compose exec -T postgres psql -U mosaic -d mosaic
+```
+
+## Cache Operations
+
+```bash
+# Valkey CLI
+docker compose exec valkey valkey-cli
+
+# Check cache health
+docker compose exec valkey valkey-cli ping
+
+# Flush cache
+docker compose exec valkey valkey-cli FLUSHALL
+```
+
+## Container Access
+
+```bash
+# API container shell
+docker compose exec api sh
+
+# Web container shell
+docker compose exec web sh
+
+# Run command in container

+docker compose exec api nc -zv valkey 6379
+```
+
+## Health Endpoints
+
+```bash
+# API health
+curl http://localhost:3001/health
+
+# Web (returns HTML)
+curl http://localhost:3000
+
+# Authentik health (if enabled)
+curl http://localhost:9000/-/health/live/
+
+# Ollama health (if enabled)
+curl http://localhost:11434/api/tags
+```
+
+## Cleanup
+
+```bash
+# Remove stopped containers
+docker compose down
+
+# Remove containers and volumes
+docker compose down -v
+
+# Remove all unused Docker resources

+docker volume prune
+```
+
+## Environment Management
+
+```bash
+# Check current environment
+docker compose config
+
+# Validate compose file
+docker compose config --quiet
+
+# Use specific env file
+docker compose --env-file .env.production up -d
+```
+
+## Profiles
+
+```bash
+# Available profiles
+# - authentik: Authentik OIDC stack
+# - ollama: Ollama AI service
+# - full: All optional services
+
+# Set profile via environment
+export COMPOSE_PROFILES=authentik,ollama
+docker compose up -d
+
+# Or in .env file
+echo "COMPOSE_PROFILES=full" >> .env
+```
+
+## Troubleshooting
+
+```bash
+# Container won't start - check logs
+docker compose logs <service>
+
+# Port conflict - check what's using the port
+lsof -i :3001
+
+# Permission errors - check permissions
+docker compose exec postgres ls -la /var/lib/postgresql/data
+
+# Network issues - recreate networks
+docker compose down
+docker network prune
+docker compose up -d
+
+# Volume issues - check volume
+docker volume inspect mosaic-postgres-data
+
+# Reset everything (DANGER: deletes all data)
+docker compose down -v
+docker system prune -af
+docker volume prune -f
+```
+
+## Performance Tuning
+
+```bash
+# View resource usage
+docker stats
+
+# Limit container resources (in docker-compose.override.yml)
+services:
+  api:
+    deploy:
+      resources:
+        limits:
+          cpus: '1.0'
+          memory: 1G
+
+# Adjust PostgreSQL settings in .env
+POSTGRES_SHARED_BUFFERS=512MB
+POSTGRES_EFFECTIVE_CACHE_SIZE=2GB
+
+# Adjust Valkey memory in .env
+VALKEY_MAXMEMORY=512mb
+```
+
+## Backup & Restore
+
+```bash
+# Backup PostgreSQL database
+docker compose exec postgres pg_dump -U mosaic mosaic > backup-$(date +%Y%m%d).sql
+
+# Backup volume
+docker run --rm \
+  -v mosaic-postgres-data:/data \

+# Docker Deployment
+
+Complete guide for deploying Mosaic Stack using Docker Compose.
+
+## Overview
+
+Mosaic Stack provides a turnkey Docker Compose setup that includes:
+
+- **PostgreSQL 17** with pgvector extension
+- **Valkey** (Redis-compatible cache)
+- **Traefik** (optional reverse proxy)
+- **Authentik** (optional OIDC provider)
+- **Ollama** (optional AI service)
+- **Mosaic API** (NestJS backend)
+- **Mosaic Web** (Next.js frontend)
+
+## Quick Start
+
+Start the entire stack with one command:
+
+```bash
+# Copy environment configuration
+cp .env.example .env
+
+# Edit .env with your settings
+nano .env
+
+# Start core services (PostgreSQL, Valkey, API, Web)
+docker compose up -d
+
+# Check service status
+docker compose ps
+
+# View logs
+docker compose logs -f
+```
+
+That's it! Your Mosaic Stack is now running:
+- Web: http://localhost:3000
+- API: http://localhost:3001
+- PostgreSQL: localhost:5432
+- Valkey: localhost:6379
+
+## Service Profiles
+
+Mosaic Stack uses Docker Compose profiles to enable optional services:
+
+### Core Services (Always Active)
+- `postgres` - PostgreSQL database
+- `valkey` - Valkey cache
+- `api` - Mosaic API
+- `web` - Mosaic Web
+
+### Optional Services (Profiles)
+
+#### Traefik (Reverse Proxy)
+```bash
+# Start with bundled Traefik
+docker compose --profile traefik-bundled up -d
+
+# Or set in .env
+COMPOSE_PROFILES=traefik-bundled
+```
+
+Services included:
+- `traefik` - Traefik reverse proxy with dashboard (http://localhost:8080)
+
+See [Traefik Integration Guide](traefik.md) for detailed configuration options including upstream mode.
+
+#### Authentik (OIDC Provider)
+```bash
+# Start with Authentik
+docker compose --profile authentik up -d
+
+# Or set in .env
+COMPOSE_PROFILES=authentik
+```
+
+Services included:
+- `authentik-postgres` - Authentik database
+- `authentik-redis` - Authentik cache
+- `authentik-server` - Authentik OIDC server (http://localhost:9000)
+- `authentik-worker` - Authentik background worker
+
+#### Ollama (AI Service)
+```bash
+# Start with Ollama
+docker compose --profile ollama up -d
+
+# Or set in .env
+COMPOSE_PROFILES=ollama
+```
+
+Services included:
+- `ollama` - Ollama LLM service (http://localhost:11434)
+
+#### All Services
+```bash
+# Start everything
+docker compose --profile full up -d
+
+# Or set in .env
+COMPOSE_PROFILES=full
+```
+
+## Deployment Modes
+
+### Turnkey Deployment (Recommended for Development)
+
+Uses all bundled services:
+
+```bash
+# Start core services
+docker compose up -d
+
+# Or with optional services
+docker compose --profile full up -d
+```
+
+### Customized Deployment (Production)
+
+Use external services for production:
+
+1. Copy override template:
+   ```bash
+   cp docker-compose.override.yml.example docker-compose.override.yml
+   ```
+
+2. Edit `docker-compose.override.yml` to:
+   - Disable bundled services
+   - Point to external services
+   - Add custom configuration
+
+3. Start stack:
+   ```bash
+   docker compose up -d
+   ```
+
+Docker automatically merges `docker-compose.yml` and `docker-compose.override.yml`.
+
+## Architecture
+
+### Network Configuration
+
+Mosaic Stack uses two Docker networks to organize service communication:
+
+#### mosaic-internal (Backend Services)
+- **Purpose**: Isolates database and cache services
+- **Services**:
+  - PostgreSQL (main database)
+  - Valkey (main cache)
+  - Authentik PostgreSQL
+  - Authentik Redis
+  - Ollama (when using bundled service)
+- **Connectivity**:
+  - Not marked as `internal: true` to allow API to reach external services
+  - API can connect to external Authentik and Ollama instances
+  - Database and cache services only accessible within Docker network
+  - No direct external access to database/cache ports (unless explicitly exposed)
+
+#### mosaic-public (Frontend Services)
+- **Purpose**: Services that need external network access
+- **Services**:
+  - Mosaic API (needs to reach Authentik OIDC and external Ollama)
+  - Mosaic Web
+  - Authentik Server (receives OIDC callbacks)
+- **Connectivity**: Full external network access for API integrations
+
+#### Network Security Notes
+
+1. **Why mosaic-internal is not marked internal**: The API service needs to:
+   - Connect to external Authentik servers for OIDC authentication
+   - Connect to external Ollama services when using remote AI
+   - Make outbound HTTP requests for integrations
+
+2. **Database/Cache Protection**: Even though the network allows external access:
+   - PostgreSQL and Valkey are NOT exposed on host ports by default
+   - Only accessible via internal Docker DNS (postgres:5432, valkey:6379)
+   - To expose for development, explicitly set ports in `.env`
+
+3. **Production Recommendations**:
+   - Use firewall rules to restrict container egress traffic
+   - Use reverse proxy (Traefik, nginx) for API/Web with TLS
+   - Use external managed PostgreSQL and Valkey services
+   - Implement network policies in orchestration platforms (Kubernetes)
+
+### Volume Management
+
+Persistent data volumes:
+
+- `mosaic-postgres-data` - PostgreSQL data
+- `mosaic-valkey-data` - Valkey persistence
+- `mosaic-authentik-postgres-data` - Authentik database
+- `mosaic-authentik-redis-data` - Authentik cache
+- `mosaic-authentik-media` - Authentik media files
+- `mosaic-authentik-certs` - Authentik certificates
+- `mosaic-authentik-templates` - Authentik templates
+- `mosaic-ollama-data` - Ollama models
+
+### Health Checks
+
+All services include health checks with automatic restart:
+
+- PostgreSQL: `pg_isready` check every 10s
+- Valkey: `valkey-cli ping` every 10s
+- API: HTTP GET /health every 30s
+- Web: HTTP GET / every 30s
+- Authentik: HTTP GET /-/health/live/ every 30s
+
+## Common Operations
+
+### View Logs
+
+```bash
+# All services
+docker compose logs -f
+
+# Specific service
+docker compose logs -f api
+
+# Last 100 lines
+docker compose logs --tail=100 api
+```
+
+### Restart Services
+
+```bash
+# Restart all
+docker compose restart
+
+# Restart specific service
+docker compose restart api
+```
+
+### Stop Services
+
+```bash
+# Stop all (keeps data)
+docker compose down
+
+# Stop and remove volumes (WARNING: deletes all data)
+docker compose down -v
+```
+
+### Execute Commands in Containers
+
+```bash
+# PostgreSQL shell
+docker compose exec postgres psql -U mosaic -d mosaic
+
+# API shell
+docker compose exec api sh
+
+# Run Prisma migrations
+docker compose exec api pnpm prisma:migrate:prod
+```
+
+### Update Services
+
+```bash
+# Pull latest images
+docker compose pull
+
+# Rebuild and restart
+docker compose up -d --build
+```
+
+## Configuration
+
+See [Configuration Guide](../3-configuration/README.md) for detailed environment variable documentation.
+
+### Key Environment Variables
+
+```bash
+# Application Ports
+API_PORT=3001
+WEB_PORT=3000
+
+# Database
+DATABASE_URL=postgresql://mosaic:password@postgres:5432/mosaic
+POSTGRES_USER=mosaic
+POSTGRES_PASSWORD=change-me
+
+# Cache
+VALKEY_URL=redis://valkey:6379
+
+# Authentication (if using Authentik)
+OIDC_ISSUER=https://auth.example.com/application/o/mosaic-stack/
+OIDC_CLIENT_ID=your-client-id
+OIDC_CLIENT_SECRET=your-client-secret
+
+# JWT
+JWT_SECRET=change-this-to-a-random-secret
+```
+
+## Troubleshooting
+
+### Service Won't Start
+
+Check logs:
+```bash
+docker compose logs <service-name>
+```
+
+Common issues:
+- Port already in use: Change port in `.env`
+- Health check failing: Wait longer or check service logs
+- Missing environment variables: Check `.env` file
+
+### Database Connection Issues
+
+1. Verify PostgreSQL is healthy:
+   ```bash
+   docker compose ps postgres
+   ```
+
+2. Check database logs:
+   ```bash
+   docker compose logs postgres
+   ```
+
+3. Test connection:
+   ```bash
+   docker compose exec postgres psql -U mosaic -d mosaic -c "SELECT 1;"
+   ```
+
+### Performance Issues
+
+1. Adjust PostgreSQL settings in `.env`:
+   ```bash
+   POSTGRES_SHARED_BUFFERS=512MB
+   POSTGRES_EFFECTIVE_CACHE_SIZE=2GB
+   POSTGRES_MAX_CONNECTIONS=200
+   ```
+
+2. Adjust Valkey memory:
+   ```bash
+   VALKEY_MAXMEMORY=512mb
+   ```
+
+3. Check resource usage:
+   ```bash
+   docker stats
+   ```
+
+### Reset Everything
+
+```bash
+# Stop and remove all containers, networks, and volumes
+docker compose down -v
+
+# Remove all Mosaic images
+docker images | grep mosaic | awk '{print $3}' | xargs docker rmi
+
+# Start fresh
+docker compose up -d --build
+```
+
+## Production Considerations
+
+### Security
+
+1. **Change default passwords** in `.env`:
+   - `POSTGRES_PASSWORD`
+   - `AUTHENTIK_POSTGRES_PASSWORD`
+   - `AUTHENTIK_SECRET_KEY`
+   - `JWT_SECRET`
+
+2. **Use secrets management**:
+   - Docker secrets
+   - External secret manager (Vault, AWS Secrets Manager)
+
+3. **Network security**:
+   - Use reverse proxy (see [Traefik Integration](traefik.md))
+   - Enable HTTPS/TLS
+   - Restrict port exposure
+
+4. **Regular updates**:
+   - Keep images updated
+   - Monitor security advisories
+
+### Backup
+
+Backup volumes regularly:
+
+```bash
+# Backup PostgreSQL
+docker compose exec postgres pg_dump -U mosaic mosaic > backup.sql
+
+# Backup volumes
+docker run --rm -v mosaic-postgres-data:/data -v $(pwd):/backup alpine tar czf /backup/postgres-data.tar.gz /data
+```
+
+### Monitoring
+
+Consider adding:
+- Prometheus for metrics
+- Grafana for dashboards
+- Loki for log aggregation
+- Alertmanager for alerts
+
+### Scaling
+
+For production scaling:
+- Use external PostgreSQL (managed service)
+- Use external Redis/Valkey cluster
+- Load balance multiple API instances
+- Use CDN for static assets
+

+# Traefik Reverse Proxy Integration
+
+Mosaic Stack supports flexible Traefik integration with three deployment modes:
+
+1. **Bundled Mode**: Self-contained Traefik instance
+2. **Upstream Mode**: Connect to external Traefik
+3. **None Mode**: Direct port exposure (no reverse proxy)
+
+## Quick Start
+
+### Bundled Mode (Recommended for New Deployments)
+
+```bash
+# 1. Copy bundled configuration
+cp .env.traefik-bundled.example .env
+
+# 2. Update passwords and secrets in .env
+# Edit POSTGRES_PASSWORD, AUTHENTIK_SECRET_KEY, JWT_SECRET, etc.
+
+# 3. Start with bundled Traefik profile
+docker compose --profile traefik-bundled up -d
+
+# 4. Access services
+# - Web: https://mosaic.local
+# - API: https://api.mosaic.local
+# - Auth: https://auth.mosaic.local
+# - Traefik Dashboard: http://localhost:8080
+```
+
+### Upstream Mode (For Existing Traefik Instances)
+
+```bash
+# 1. Ensure external Traefik network exists
+docker network create traefik-public
+
+# 2. Copy upstream configuration
+cp .env.traefik-upstream.example .env
+
+# 3. Update .env with your domains and secrets
+
+# 4. Create override file for network attachment
+cp docker-compose.override.yml.example docker-compose.override.yml
+
+# 5. Edit docker-compose.override.yml and uncomment upstream network section
+
+# 6. Start services
+docker compose up -d
+```
+
+### None Mode (Direct Port Access)
+
+```bash
+# 1. Use default .env.example
+cp .env.example .env
+
+# 2. Ensure TRAEFIK_MODE=none (default)
+
+# 3. Start services
+docker compose up -d
+
+# 4. Access services on standard ports
+# - Web: http://localhost:3000
+# - API: http://localhost:3001
+# - Auth: http://localhost:9000
+```

+## Deployment Scenarios
+
+### Local Development with Self-Signed Certificates
+
+```bash
+# .env configuration
+TRAEFIK_MODE=bundled
+TRAEFIK_ENABLE=true
+TRAEFIK_TLS_ENABLED=true
+TRAEFIK_ACME_EMAIL=  # Empty for self-signed
+MOSAIC_API_DOMAIN=api.mosaic.local
+MOSAIC_WEB_DOMAIN=mosaic.local
+MOSAIC_AUTH_DOMAIN=auth.mosaic.local
+
+# Start services
+docker compose --profile traefik-bundled up -d
+
+# Add to /etc/hosts
+echo "127.0.0.1 mosaic.local api.mosaic.local auth.mosaic.local" | sudo tee -a /etc/hosts
+```
+
+Browser will show certificate warnings (expected for self-signed certs).
+
+### Production with Let's Encrypt
+
+```bash
+# .env configuration
+TRAEFIK_MODE=bundled
+TRAEFIK_ENABLE=true
+TRAEFIK_TLS_ENABLED=true
+TRAEFIK_ACME_EMAIL=admin@example.com
+TRAEFIK_CERTRESOLVER=letsencrypt
+MOSAIC_API_DOMAIN=api.example.com
+MOSAIC_WEB_DOMAIN=example.com
+MOSAIC_AUTH_DOMAIN=auth.example.com
+```
+
+**Prerequisites:**
+1. DNS records pointing to your server
+2. Ports 80 and 443 accessible from internet
+3. Uncomment ACME configuration in `docker/traefik/traefik.yml`
+
+```yaml
+# docker/traefik/traefik.yml
+certificatesResolvers:
+  letsencrypt:
+    acme:
+      email: "${TRAEFIK_ACME_EMAIL}"
+      storage: "/letsencrypt/acme.json"
+      httpChallenge:
+        entryPoint: web
+```
+
+### Connecting to Existing Traefik (web1.corp.uscllc.local)
+
+For the shared development environment at `~/src/traefik`:
+
+```bash
+# 1. Verify external Traefik is running
+docker ps | grep traefik
+
+# 2. Verify external network exists
+docker network ls | grep traefik-public
+
+# 3. Configure .env
+TRAEFIK_MODE=upstream
+TRAEFIK_ENABLE=true
+TRAEFIK_NETWORK=traefik-public
+TRAEFIK_DOCKER_NETWORK=traefik-public
+MOSAIC_API_DOMAIN=mosaic-api.uscllc.com
+MOSAIC_WEB_DOMAIN=mosaic.uscllc.com
+MOSAIC_AUTH_DOMAIN=mosaic-auth.uscllc.com
+
+# 4. Create docker-compose.override.yml
+cp docker-compose.override.yml.example docker-compose.override.yml
+
+# 5. Edit docker-compose.override.yml - uncomment network section
+# networks:
+#   traefik-public:
+#     external: true
+#     name: traefik-public
+
+# 6. Add services to external network
+# api:
+#   networks:
+#     - traefik-public
+# web:
+#   networks:
+#     - traefik-public
+# authentik-server:
+#   networks:
+#     - traefik-public
+
+# 7. Start services
+docker compose up -d
+```
+
+Services will be auto-discovered by the external Traefik instance.
+
+## Advanced Configuration
+
+### Custom Middleware
+
+Add authentication or rate limiting via Traefik middleware:
+
+```yaml
+# docker-compose.override.yml
+services:
+  traefik:
+    labels:
+      # Define basic auth middleware
+      - "traefik.http.middlewares.auth.basicauth.users=admin:$$apr1$$xyz..."
+      # Define rate limit middleware
+      - "traefik.http.middlewares.ratelimit.ratelimit.average=100"
+      - "traefik.http.middlewares.ratelimit.ratelimit.burst=50"
+
+  api:
+    labels:
+      # Apply middleware to API router
+      - "traefik.http.routers.mosaic-api.middlewares=auth@docker,ratelimit@docker"
+```
+
+Generate basic auth password:
+```bash
+echo $(htpasswd -nb admin your-password) | sed -e s/\\$/\\$\\$/g
+```
+
+### Custom TLS Certificates
+
+To use custom certificates instead of Let's Encrypt:
+
+```yaml
+# docker/traefik/dynamic/tls.yml
+tls:
+  certificates:
+    - certFile: /certs/domain.crt
+      keyFile: /certs/domain.key
+```
+
+Mount certificate directory:
+```yaml
+# docker-compose.override.yml
+services:
+  traefik:
+    volumes:
+      - ./certs:/certs:ro
+```
+
+### Multiple Domains
+
+Route multiple domains to different services:
+
+```yaml
+# .env
+MOSAIC_WEB_DOMAIN=mosaic.local,app.mosaic.local,www.mosaic.local
+
+# Traefik will match all domains
+```
+
+Or use override for complex routing:
+
+```yaml
+# docker-compose.override.yml
+services:
+  web:
+    labels:
+      - "traefik.http.routers.mosaic-web.rule=Host(`mosaic.local`) || Host(`app.mosaic.local`)"
+      - "traefik.http.routers.mosaic-web-www.rule=Host(`www.mosaic.local`)"
+      - "traefik.http.routers.mosaic-web-www.middlewares=redirect-www"
+      - "traefik.http.middlewares.redirect-www.redirectregex.regex=^https://www.mosaic.local/(.*)"
+      - "traefik.http.middlewares.redirect-www.redirectregex.replacement=https://mosaic.local/$${1}"
+```
+
+## Troubleshooting
+
+### Services Not Accessible via Domain
+
+**Check Traefik is running:**
+```bash
+docker ps | grep traefik
+```
+
+**Check Traefik dashboard:**
+```bash
+# Bundled mode
+open http://localhost:8080
+
+# Check registered routers
+curl http://localhost:8080/api/http/routers | jq
+```
+
+**Verify labels are applied:**
+```bash
+docker inspect mosaic-api | jq '.Config.Labels'
+```
+
+**Check DNS/hosts file:**
+```bash
+# Local development
+cat /etc/hosts | grep mosaic
+```
+
+### Certificate Errors
+
+**Self-signed certificates (development):**
+- Browser warnings are expected
+- Add exception in browser or import CA certificate
+
+**Let's Encrypt failures:**
+```bash
+# Check Traefik logs
+docker logs mosaic-traefik
+
+# Verify ACME email is set
+docker exec mosaic-traefik cat /etc/traefik/traefik.yml
+
+# Check certificate storage
+docker exec mosaic-traefik ls -la /letsencrypt/
+```
+
+### Upstream Mode Not Connecting
+
+**Verify external network exists:**
+```bash
+docker network ls | grep traefik-public
+```
+
+**Create network if missing:**
+```bash
+docker network create traefik-public
+```
+
+**Check service network attachment:**
+```bash
+docker inspect mosaic-api | jq '.NetworkSettings.Networks'
+```
+
+**Verify external Traefik can see services:**
+```bash
+# From external Traefik container
+docker exec <external-traefik-container> traefik healthcheck
+```
+
+### Port Conflicts
+
+**Bundled mode port conflicts:**
+```bash
+# Check what's using ports
+sudo lsof -i :80
+sudo lsof -i :443
+sudo lsof -i :8080
+
+# Change ports in .env
+TRAEFIK_HTTP_PORT=8000
+TRAEFIK_HTTPS_PORT=8443
+TRAEFIK_DASHBOARD_PORT=8081
+```
+
+### Dashboard Not Accessible
+
+**Check dashboard is enabled:**
+```bash
+# In .env
+TRAEFIK_DASHBOARD_ENABLED=true
+```
+
+**Verify Traefik configuration:**
+```bash
+docker exec mosaic-traefik cat /etc/traefik/traefik.yml | grep -A5 "api:"
+```
+
+**Access dashboard:**
+```bash
+# Default
+http://localhost:8080/dashboard/
+
+# Custom port
+http://localhost:${TRAEFIK_DASHBOARD_PORT}/dashboard/
+```
+
+## Security Considerations
+
+### Production Checklist
+
+- [ ] Use Let's Encrypt or valid SSL certificates
+- [ ] Disable Traefik dashboard or protect with authentication
+- [ ] Enable HTTP to HTTPS redirect
+- [ ] Configure rate limiting middleware
+- [ ] Use strong passwords for all services
+- [ ] Restrict Traefik dashboard to internal network
+- [ ] Enable Traefik access logs for audit trail
+- [ ] Regularly update Traefik image version
+
+### Securing the Dashboard
+
+**Option 1: Disable in production**
+```bash
+TRAEFIK_DASHBOARD_ENABLED=false
+```
+
+**Option 2: Add basic authentication**
+```yaml
+# docker-compose.override.yml
+services:
+  traefik:
+    command:
+      - "--configFile=/etc/traefik/traefik.yml"
+      - "--api.dashboard=true"
+    labels:
+      - "traefik.http.routers.dashboard.rule=Host(`traefik.example.com`)"
+      - "traefik.http.routers.dashboard.service=api@internal"
+      - "traefik.http.routers.dashboard.middlewares=auth"
+      - "traefik.http.middlewares.auth.basicauth.users=admin:$$apr1$$xyz..."
+```
+
+**Option 3: IP whitelist**
+```yaml
+# docker-compose.override.yml
+services:
+  traefik:
+    labels:
+      - "traefik.http.middlewares.ipwhitelist.ipwhitelist.sourcerange=127.0.0.1/32,10.0.0.0/8"
+      - "traefik.http.routers.dashboard.middlewares=ipwhitelist"
+```
+
+## Performance Tuning
+
+### Connection Limits
+
+```yaml
+# docker/traefik/traefik.yml
+entryPoints:
+  web:
+    address: ":80"
+    transport:
+      respondingTimeouts:
+        readTimeout: 60
+        writeTimeout: 60
+        idleTimeout: 180
+  websecure:
+    address: ":443"
+    transport:
+      respondingTimeouts:
+        readTimeout: 60
+        writeTimeout: 60
+        idleTimeout: 180
+```
+
+### Rate Limiting
+
+```yaml
+# docker-compose.override.yml
+services:
+  traefik:
+    labels:
+      - "traefik.http.middlewares.ratelimit.ratelimit.average=100"
+      - "traefik.http.middlewares.ratelimit.ratelimit.burst=200"
+      - "traefik.http.middlewares.ratelimit.ratelimit.period=1s"
+```
+
+## Testing
+
+Integration tests are available to verify Traefik configuration:
+
+```bash
+# Run all Traefik tests
+./tests/integration/docker/traefik.test.sh all
+
+# Test specific mode
+./tests/integration/docker/traefik.test.sh bundled
+./tests/integration/docker/traefik.test.sh upstream
+./tests/integration/docker/traefik.test.sh none
+```
+
+See `tests/integration/docker/README.md` for details.
+
+## Migration Guide

+# Activity Logging API
+
+The Activity Logging API provides comprehensive audit trail and activity tracking functionality for the Mosaic Stack platform. It logs user actions, workspace changes, task/event modifications, and authentication events.
+
+## Overview
+
+Activity logs are automatically created for:
+- **CRUD Operations**: Task, event, project, and workspace modifications
+- **Authentication Events**: Login, logout, password resets
+- **User Actions**: Task assignments, workspace member changes
+- **System Events**: Configuration updates, permission changes
+
+All activity logs are workspace-scoped and support multi-tenant isolation through Row-Level Security (RLS).
+
+## Endpoints

+
+## Enums
+
+### ActivityAction
+
+Actions that can be logged:
+
+- `CREATED` - Entity was created
+- `UPDATED` - Entity was updated
+- `DELETED` - Entity was deleted
+- `COMPLETED` - Task or project was completed
+- `ASSIGNED` - Task was assigned to a user
+- `COMMENTED` - Comment was added (future use)
+- `LOGIN` - User logged in
+- `LOGOUT` - User logged out
+- `PASSWORD_RESET` - Password was reset
+- `EMAIL_VERIFIED` - Email was verified
+
+### EntityType
+
+Types of entities that can be tracked:
+
+- `TASK` - Task entity
+- `EVENT` - Calendar event
+- `PROJECT` - Project
+- `WORKSPACE` - Workspace
+- `USER` - User profile
+
+---
+
+## Automatic Logging
+
+The Activity Logging system includes an interceptor that automatically logs:
+
+- **POST requests** → `CREATED` action
+- **PATCH/PUT requests** → `UPDATED` action
+- **DELETE requests** → `DELETED` action
+
+The interceptor extracts:
+- User information from the authenticated session
+- Workspace context from request
+- IP address and user agent from HTTP headers
+- Entity ID from route parameters or response
+
+---
+
+## Manual Logging
+
+For custom logging scenarios, use the `ActivityService` helper methods:
+
+```typescript
+import { ActivityService } from '@/activity/activity.service';
+
+@Injectable()
+export class TaskService {
+  constructor(private activityService: ActivityService) {}
+
+  async createTask(data, userId, workspaceId) {
+    const task = await this.prisma.task.create({ data });
+
+    // Log task creation
+    await this.activityService.logTaskCreated(
+      workspaceId,
+      userId,
+      task.id,
+      { title: task.title }
+    );
+
+    return task;
+  }
+}
+```
+
+### Available Helper Methods
+
+#### Task Activities
+- `logTaskCreated(workspaceId, userId, taskId, details?)`
+- `logTaskUpdated(workspaceId, userId, taskId, details?)`
+- `logTaskDeleted(workspaceId, userId, taskId, details?)`
+- `logTaskCompleted(workspaceId, userId, taskId, details?)`
+- `logTaskAssigned(workspaceId, userId, taskId, assigneeId)`
+
+#### Event Activities
+- `logEventCreated(workspaceId, userId, eventId, details?)`
+- `logEventUpdated(workspaceId, userId, eventId, details?)`
+- `logEventDeleted(workspaceId, userId, eventId, details?)`
+
+#### Project Activities
+- `logProjectCreated(workspaceId, userId, projectId, details?)`
+- `logProjectUpdated(workspaceId, userId, projectId, details?)`
+- `logProjectDeleted(workspaceId, userId, projectId, details?)`
+
+#### Workspace Activities
+- `logWorkspaceCreated(workspaceId, userId, details?)`
+- `logWorkspaceUpdated(workspaceId, userId, details?)`
+- `logWorkspaceMemberAdded(workspaceId, userId, memberId, role)`
+- `logWorkspaceMemberRemoved(workspaceId, userId, memberId)`
+
+#### User Activities
+- `logUserUpdated(workspaceId, userId, details?)`
+
+---
+
+## Security & Privacy
+
+### Multi-Tenant Isolation
+
+All activity logs are scoped to workspaces using Row-Level Security (RLS). Users can only access activity logs for workspaces they belong to.
+
+### Data Retention
+
+Activity logs are retained indefinitely by default. Consider implementing a retention policy based on:
+- Compliance requirements
+- Storage constraints
+- Business needs
+
+### Sensitive Data
+
+Activity logs should NOT contain:
+- Passwords or authentication tokens
+- Credit card information
+- Personal health information
+- Other sensitive PII
+
+Store only metadata needed for audit purposes. Use the `details` field for non-sensitive context.
+
+---
+
+## Best Practices
+
+### 1. Use Descriptive Details
+
+Include enough context to understand what changed:
+
+```typescript
+// Good
+await activityService.logTaskUpdated(workspaceId, userId, taskId, {
+  changes: {
+    status: { from: 'NOT_STARTED', to: 'IN_PROGRESS' },
+    assignee: { from: null, to: 'user-456' }
+  }
+});
+
+// Less useful
+await activityService.logTaskUpdated(workspaceId, userId, taskId);
+```
+
+### 2. Log Business-Critical Actions
+
+Prioritize logging actions that:
+- Change permissions or access control
+- Delete data
+- Modify billing or subscription
+- Export data
+- Change security settings
+
+### 3. Query Efficiently
+
+Use appropriate filters to reduce data transfer:
+
+```typescript
+// Efficient - filters at database level
+const activities = await fetch('/api/activity?workspaceId=xxx&entityType=TASK&page=1&limit=50');
+
+// Inefficient - transfers all data then filters
+const activities = await fetch('/api/activity?workspaceId=xxx');
+const taskActivities = activities.filter(a => a.entityType === 'TASK');
+```
+
+### 4. Display User-Friendly Activity Feeds
+
+Transform activity logs into human-readable messages:
+
+```typescript
+function formatActivityMessage(activity: ActivityLog) {
+  const { user, action, entityType, details } = activity;
+
+  switch (action) {
+    case 'CREATED':
+      return `${user.name} created ${entityType.toLowerCase()} "${details.title}"`;
+    case 'UPDATED':
+      return `${user.name} updated ${entityType.toLowerCase()}`;
+    case 'DELETED':
+      return `${user.name} deleted ${entityType.toLowerCase()}`;
+    default:
+      return `${user.name} performed ${action}`;
+  }
+}
+```
+
+---
+
+## Error Handling
+
+Activity logging failures should NOT block the primary operation. The interceptor and service methods handle errors gracefully:
+
+```typescript
+try {
+  await activityService.logActivity(data);
+} catch (error) {
+  // Log error but don't throw
+  logger.error('Failed to log activity', error);
+}
+```
+
+If activity logging is critical for compliance, implement synchronous validation before the operation completes.
+
+---
+
+## Performance Considerations
+
+### Indexing
+
+The following indexes optimize common queries:
+
+- `workspaceId` - Filter by workspace
+- `workspaceId + createdAt` - Recent activities per workspace
+- `entityType + entityId` - Audit trail queries
+- `userId` - User activity history
+- `action` - Filter by action type
+
+### Pagination
+
+Always use pagination for activity queries. Default limit is 50 items, maximum is 100.
+
+### Background Processing
+
+For high-volume systems, consider:
+- Async activity logging with message queues
+- Batch inserts for multiple activities
+- Separate read replicas for reporting
