  npx agentic-flow federation start --db-path ./data/hub.db

  # Start hub on custom port
  npx agentic-flow federation start --port 9443 --verbose

  # Spawn ephemeral agent (5 minute lifetime)
  npx agentic-flow federation spawn --tenant acme-corp

  # Spawn agent with custom lifetime
  npx agentic-flow federation spawn --tenant acme-corp --lifetime 600 --type researcher

  # Show hub statistics
  npx agentic-flow federation stats

  # Show system status
  npx agentic-flow federation status

  # Run collaboration test
  npx agentic-flow federation test

ARCHITECTURE:
  Hub: Persistent central database (SQLite + AgentDB)
    • Episode metadata storage
    • Vector memory with HNSW indexing (150x faster)
    • Tenant isolation via sessionId prefixes
    • Change log for synchronization

  Agents: Ephemeral local databases (:memory:)
    • Short-lived (5 seconds to 15 minutes)
    • Pull memories from hub on spawn
    • Push new memories to hub during work
    • Destroyed on cleanup (memory persists in hub)

  Memory Persistence:
    • Hub database outlives all agents
    • New agents can access memories from dead agents
    • Multi-generation learning enabled
    • Semantic search for pattern discovery

BENEFITS:
  ✅ Memory outlives agents         - Persistent learning across generations
  ✅ Tenant isolation               - Multi-tenant with zero data leakage
  ✅ Semantic search                - Find similar patterns via vector similarity
  ✅ 150x faster search             - HNSW indexing vs brute force
  ✅ Scalable architecture          - Ready for 100+ concurrent agents
  ✅ WebSocket protocol             - Real-time synchronization
  ✅ Zero-trust security            - JWT auth + AES-256 encryption
