Storage Architecture

• Hub: Persistent (SQLite + AgentDB) - Disk storage
• Agents: Ephemeral (:memory:) - RAM only, 5s-15min lifetime
• Memory Persistence: Hub outlives all agents
• Multi-Generation Learning: New agents access memories from dead agents

✅ Testing Results

Help Command

```bash
$ node dist/cli-proxy.js federation help

🌐 Federation Hub CLI - Ephemeral Agent Management

USAGE:
npx agentic-flow federation [options]

COMMANDS:
start Start federation hub server
spawn Spawn ephemeral agent
stats Show hub statistics
status Show federation system status
test Run multi-agent collaboration test
help Show this help message
...
```

Status Command

```bash
$ node dist/cli-proxy.js federation status

🔍 Federation System Status
════════════════════════════════════════════════════════════

Components:
✅ FederationHubServer - WebSocket hub for agent sync
✅ FederationHubClient - WebSocket client for agents
✅ EphemeralAgent - Short-lived agent lifecycle
✅ SecurityManager - JWT authentication & encryption
✅ AgentDB Integration - Vector memory storage (150x faster)

Features:
✅ Tenant Isolation - Multi-tenant memory separation
✅ Persistent Hub - SQLite + AgentDB storage
✅ Ephemeral Agents - :memory: databases (5s-15min lifetime)
✅ Semantic Search - HNSW vector indexing
✅ Multi-Generation - Agents learn from past agents
⏳ QUIC Transport - Native QUIC planned (WebSocket fallback)
...
```

Main CLI Integration

```bash
$ npx agentic-flow --help | grep -A10 "FEDERATION COMMANDS"

FEDERATION COMMANDS:
npx agentic-flow federation start Start federation hub server
npx agentic-flow federation spawn Spawn ephemeral agent
npx agentic-flow federation stats Show hub statistics
npx agentic-flow federation status Show federation system status
npx agentic-flow federation test Run multi-agent collaboration test
npx agentic-flow federation help Show federation help

Federation enables ephemeral agents (5s-15min lifetime) with persistent memory.
Hub stores memories permanently; agents access past learnings from dead agents.
```

Prepared by: @ruvnet
Issue Type: Feature Implementation
Priority: High
Labels: enhancement, documentation, cli, federation, agentdb

The issue describes completed federation CLI work rather than an open change. Review src/cli/federation-cli.ts, src/cli-proxy.ts, and src/utils/cli.ts, then use the documented command examples and testing results to verify the integration; the listed Stats API and agent-management commands remain future work.
