```

### Data Flow

1. Agent action → Local AgentDB (0.1ms - fast!)
2. Sync → Supabase PostgreSQL (25ms)
3. CDC → Real-time broadcast to all agents
4. Event → Other agents receive and process
5. Update → Agents update local cache

## 🔧 Configuration

### Environment Variables

```bash
# Required
SUPABASE_URL=https://xxxxx.supabase.co
SUPABASE_ANON_KEY=eyJhbGc...

# Optional
SUPABASE_SERVICE_ROLE_KEY=eyJhbGc...
FEDERATION_VECTOR_BACKEND=hybrid  # agentdb | pgvector | hybrid

# Cloud only (persistent, higher latency)
FEDERATION_VECTOR_BACKEND=pgvector

# Best of both (recommended)
FEDERATION_VECTOR_BACKEND=hybrid
```

## 🔒 Security

### Row Level Security (RLS)

Automatic multi-tenant isolation at database level:

```

### API Keys

- **Anon Key**: Client-side (RLS enforced)
- **Service Role Key**: Server-side (bypasses RLS - keep secret!)

### Encryption

- ✅ All data encrypted in transit (TLS)
- ✅ All data encrypted at rest (AES-256)
- ✅ Automatic backups encrypted
