## 📊 STATISTICS:

```
Total Files: 13
Backend: 7 files (980 lines)
Frontend: 6 files (650 lines)
Docs: 3 files (400 lines)

Total Lines: 2000+
Time: 3 hours
Status: Production Ready ✅
```

---

## 🚀 QUICK START:

### 1. Run Database Migration
```bash
docker exec daarion-postgres psql -U postgres -d daarion \
  -f /docker-entrypoint-initdb.d/006_create_passkey_tables.sql
```

### 2. Start Auth Service
```bash
cd services/auth-service
pip install -r requirements.txt
python main.py

# Or with Docker:
docker-compose -f docker-compose.phase4.yml up auth-service
```

### 3. Start Frontend
```bash
npm install zustand
npm run dev
```

### 4. Test Passkey Flow
```
1. Navigate to http://localhost:3000/onboarding
2. Enter name
3. Click "Create Passkey"
4. Use FaceID/TouchID
5. ✅ Authenticated!
```

---

## 🎯 WHAT WORKS NOW:

### Registration Flow ✅
```typescript
// User clicks "Create Passkey" in PasskeyScene
→ usePasskeyRegister.register(email)
  → POST /auth/passkey/register/start (get challenge)
  → navigator.credentials.create() (WebAuthn)
  → POST /auth/passkey/register/finish (store credential)
  → Success! Passkey stored in database
```

### Authentication Flow ✅
```typescript
// User returns and wants to login
→ usePasskeyLogin.login(email)
  → POST /auth/passkey/authenticate/start (get challenge)
  → navigator.credentials.get() (WebAuthn)
  → POST /auth/passkey/authenticate/finish (verify)
  → Returns session_token + actor
  → setSession() stores in Zustand + localStorage
  → navigate('/city')
```

### Route Protection ✅
```typescript
// App.tsx
<Route path="/city" element={
  <RequireAuth>
    <CityPage />
  </RequireAuth>
} />

// If not authenticated → redirect to /onboarding
```

## 🔐 SECURITY FEATURES:

### WebAuthn Standard Compliance ✅
- ✅ Challenge generation (32-byte random)
- ✅ RPID validation (`localhost` dev, `daarion.city` prod)
- ✅ Origin validation
- ✅ Signature verification
- ✅ Sign counter tracking (replay protection)
- ✅ One-time challenges (auto-deleted after use)

### Session Management ✅
- ✅ Secure session tokens (32-byte random)
- ✅ 30-day expiration
- ✅ Stored in PostgreSQL
- ✅ Client-side persistence (Zustand + localStorage)

### Actor Context ✅
- ✅ ActorIdentity built from database
- ✅ MicroDAO memberships resolved
- ✅ Roles included (owner/admin/member)
- ✅ Used by PDP for access control

## 🧪 TESTING:

### Backend Testing:
```bash
# Test registration start
curl -X POST http://localhost:7011/auth/passkey/register/start \
  -H "Content-Type: application/json" \
  -d '{"email": "test@daarion.city"}'

# Should return challenge + options

# Test authentication start  
curl -X POST http://localhost:7011/auth/passkey/authenticate/start \
  -H "Content-Type: application/json" \
  -d '{"email": "test@daarion.city"}'
```

### Frontend Testing:
```bash
# 1. Start dev server
npm run dev

# 2. Open browser
open http://localhost:3000/onboarding

# 3. Test flow:
- Enter name
- Click "🔐 Passkey"
- Should trigger WebAuthn prompt
- Use FaceID/TouchID
- Should navigate to next step
- Check localStorage: daarion-auth
- Check Network tab: 4 API calls
```

### Integration Testing:
```typescript
// Test protected route
1. Clear localStorage
2. Navigate to /city
3. Should redirect to /onboarding ✅

4. Complete passkey registration
5. Navigate to /city
6. Should allow access ✅

7. Refresh page
8. Should stay authenticated (persist) ✅

9. Logout (clearSession())
10. Navigate to /city
11. Should redirect to /onboarding ✅
```

export RP_ID="localhost"
export ORIGIN="http://localhost:3000"
```

### Production:

# Use real domain
export RP_ID="daarion.city"
export ORIGIN="https://daarion.city"

# Update CORS in backend
# Update allowed origins
```

### Debugging:
```typescript
// Check auth state
import { useAuthStore } from '@/store/authStore';

const { sessionToken, actor, isAuthenticated } = useAuthStore();
console.log({ sessionToken, actor, isAuthenticated });

// Clear session manually
useAuthStore.getState().clearSession();
