```

---

## 🚀 Quick Start

### 1. Set Up Environment

```bash
# Copy example env
cp .env.phase3.example .env.phase3

# Edit with your API keys
nano .env.phase3
```

**Required:**
- `OPENAI_API_KEY` — for GPT-4

**Optional:**
- `DEEPSEEK_API_KEY` — for DeepSeek R1
- Local Ollama — install & run separately

### 2. Start Services

```bash
# Make scripts executable (already done)
chmod +x scripts/start-phase3.sh scripts/stop-phase3.sh

# Start all services
./scripts/start-phase3.sh
```

**Services will start:**
- llm-proxy (7007)
- memory-orchestrator (7008)
- toolcore (7009)
- agent-runtime (7006)
- agent-filter (7005)
- router (8000)
- messaging-service (7004)
- PostgreSQL (5432)
- NATS (4222)

### 3. Verify Health

```bash
# Check all services
curl http://localhost:7007/health  # LLM Proxy
curl http://localhost:7008/health  # Memory
curl http://localhost:7009/health  # Toolcore
curl http://localhost:7006/health  # Runtime
```

### 4. Test Real LLM

```bash
# Test LLM Proxy directly
curl -X POST http://localhost:7007/internal/llm/proxy \
  -H "Content-Type: application/json" \
  -H "X-Internal-Secret: dev-secret-token" \
  -d '{
    "model": "gpt-4.1-mini",
    "messages": [
      {"role": "user", "content": "Hello!"}
    ],
    "metadata": {
      "agent_id": "agent:test",
      "microdao_id": "microdao:daarion"
    }
  }'
```

**Expected:** Real GPT-4 response!

### 5. Test in Messenger

```bash
# Open Messenger UI
open http://localhost:8899/messenger

# Type: "Hello Sofia!"
# Wait 3-5 seconds
# See real LLM response (not mock)!
```

## ✅ Acceptance Criteria

### LLM Proxy:
- ✅ 3 providers working (OpenAI, DeepSeek, Local)
- ✅ Model routing from config
- ✅ Usage logging per agent
- ✅ Rate limiting (10 req/min)
- ✅ Graceful fallback if provider unavailable

### Memory Orchestrator:
- ✅ Query returns relevant memories
- ✅ Store saves new memories
- ✅ Vector search (pgvector or fallback)
- ✅ Short/mid/long-term backends
- ✅ agent-runtime integration

### Toolcore:
- ✅ Tool registry loaded from config
- ✅ 3 tools defined (projects.list, task.create, followup.create)
- ✅ Permission checks work
- ✅ HTTP executor functional
- ✅ Timeouts handled

### Integration:
- ✅ agent-runtime calls llm-proxy
- ✅ agent-runtime uses memory
- ✅ All services in docker-compose
- ✅ Health checks pass
- ✅ Start/stop scripts work

## 🎓 What You Can Do Now

### Test Real LLM:
```bash
# In Messenger
"Sofia, explain Phase 3 architecture"
→ Gets real GPT-4 response!
```

### Test Memory:
```bash
# First message
"Sofia, remember: Phase 3 started on Nov 24"

# Later
"Sofia, when did Phase 3 start?"
→ Should recall from memory!
```

### Test Tools (when tool services ready):
```bash
"Sofia, list all projects"
→ Calls toolcore → projects-service
```

---

## 🔜 Next Steps

### Option A: Deploy Phase 3
```bash
./scripts/start-phase3.sh
# Test thoroughly
# Deploy to production
```

### Option B: Start Agent Hub UI
```bash
# Read spec
cat docs/tasks/AGENT_HUB_UI_TASK.md

# Start implementation
# 3-4 weeks estimated
```

### Option C: Phase 4 Planning
- Usage & Billing system
- Security (PDP/PEP)
- Advanced monitoring
- Agent marketplace

## 🐛 Troubleshooting

### LLM Proxy not working?
```bash
# Check API key
docker logs daarion-llm-proxy | grep "OPENAI_API_KEY"

# Test directly
curl https://api.openai.com/v1/models \
  -H "Authorization: Bearer $OPENAI_API_KEY"
```

### Memory not working?
```bash
# Check PostgreSQL
docker logs daarion-postgres

# Check pgvector
docker exec daarion-postgres psql -U postgres -d daarion \
  -c "CREATE EXTENSION IF NOT EXISTS vector;"
```

### Services not starting?
```bash
# Check logs
docker-compose -f docker-compose.phase3.yml logs -f

# Rebuild
docker-compose -f docker-compose.phase3.yml build --no-cache
```

## 💡 Key Insights

### What Works:
1. **Modular architecture** — each service independent
2. **Graceful fallbacks** — services work without dependencies
3. **Config-driven** — no code changes for new models/tools
4. **Production-ready** — health checks, error handling, logging

### What's Next:
1. **Real tools** — implement projects-service endpoints
2. **Advanced memory** — tune RAG parameters
3. **Cost tracking** — Usage Engine integration
