## 🔐 Authentication System (FULLY IMPLEMENTED)

### Zitadel OAuth2/OIDC Integration

**Module:** `src/auth/zitadel.rs`

#### Implemented Features:

1. **OAuth2 Authorization Flow**
   - Authorization URL generation with CSRF protection
   - Authorization code exchange for tokens
   - Automatic token refresh handling

2. **User Management**
   - User info retrieval from OIDC userinfo endpoint
   - Token introspection and validation
   - JWT token decoding and sub claim extraction

3. **Workspace Management**
   - Per-user workspace directory structure
   - Isolated VectorDB storage (email, drive)
   - Session cache management
   - Preferences and settings persistence
   - Temporary file cleanup

4. **API Endpoints** (src/auth/mod.rs)
   ```
   GET  /api/auth/login    - Generate OAuth authorization URL
   GET  /api/auth/callback - Handle OAuth callback and create session
   GET  /api/auth          - Anonymous/legacy auth handler
   ```

#### Environment Configuration:
```env
ZITADEL_ISSUER_URL=https://your-zitadel-instance.com
ZITADEL_CLIENT_ID=your_client_id
ZITADEL_CLIENT_SECRET=your_client_secret
ZITADEL_REDIRECT_URI=https://yourapp.com/api/auth/callback
ZITADEL_PROJECT_ID=your_project_id
```

#### Workspace Structure:
```
work/
├── {bot_id}/
│   └── {user_id}/
│       ├── vectordb/
│       │   ├── emails/    # Email embeddings
│       │   └── drive/     # Document embeddings
│       ├── cache/
│       │   ├── email_metadata.db
│       │   └── drive_metadata.db
│       ├── preferences/
│       │   ├── email_settings.json
│       │   └── drive_sync.json
│       └── temp/          # Temporary processing files
```

#### Session Manager Extensions:

**New Method:** `get_or_create_authenticated_user()`
- Creates or updates OAuth-authenticated users
- Stores username and email from identity provider
- Maintains updated_at timestamp for profile sync
- No password hash required (OAuth users)

---

## 📱 Microsoft Teams Integration (FULLY WIRED)

**Module:** `src/channels/teams.rs`

### Implemented Features:

1. **Bot Framework Webhook Handler**
   - Receives Teams messages via webhook
   - Validates Bot Framework payloads
   - Processes message types (message, event, invoke)

2. **OAuth Token Management**
   - Automatic token acquisition from Microsoft Identity
   - Supports both multi-tenant and single-tenant apps
   - Token caching and refresh

3. **Message Processing**
   - Session management per Teams user
   - Redis-backed session storage
   - Fallback to in-memory sessions

4. **Rich Messaging**
   - Text message sending
   - Adaptive Cards support
   - Interactive actions and buttons
   - Card submissions handling

5. **API Endpoint**
   ```
   POST /api/teams/messages - Teams webhook endpoint
   ```

### Environment Configuration:
```env
TEAMS_APP_ID=your_microsoft_app_id
TEAMS_APP_PASSWORD=your_app_password
TEAMS_SERVICE_URL=https://smba.trafficmanager.net/br/
TEAMS_TENANT_ID=your_tenant_id (optional for multi-tenant)
```

### Usage Flow:
1. Teams sends message → `/api/teams/messages`
2. `TeamsAdapter::handle_incoming_message()` validates payload
3. `process_message()` extracts user/conversation info
4. `get_or_create_session()` manages user session (Redis or in-memory)
5. `process_with_bot()` processes through bot orchestrator
6. `send_message()` or `send_card()` returns response to Teams

## 📊 Enterprise-Grade Linting Configuration

**File:** `Cargo.toml`

```toml
[lints.rust]
unused_imports = "warn"    # Keep import hygiene visible
unused_variables = "warn"  # Catch actual bugs
unused_mut = "warn"        # Maintain code quality

[lints.clippy]
all = "warn"              # Enable all clippy lints
pedantic = "warn"         # Pedantic lints for quality
nursery = "warn"          # Experimental lints
cargo = "warn"            # Cargo-specific lints
```

### Why No `dead_code = "allow"`?

Infrastructure code is **actively being integrated**, not suppressed. The remaining warnings represent:
- Planned features with documented implementation paths
- Utility functions for future API endpoints
- Optional configuration structures
- Test utilities and helpers

## 📝 Developer Notes

### Adding New Channel Integration

1. **Create adapter** in `src/channels/`
2. **Implement traits:** `ChannelAdapter` or create custom
3. **Add webhook handler** with route function
4. **Wire into main.rs** router
5. **Configure environment** variables
6. **Update this document**

### Example Pattern (Teams):
```rust
// 1. Define adapter
pub struct TeamsAdapter {
    pub state: Arc<AppState>,
    // ... config
}

// 2. Implement message handling
impl TeamsAdapter {
    pub async fn handle_incoming_message(&self, payload: Json<Message>) -> Result<StatusCode> {
        // Process message
    }
}

// 3. Create router
pub fn router(state: Arc<AppState>) -> Router {
    let adapter = Arc::new(TeamsAdapter::new(state));
    Router::new().route("/messages", post(move |payload| adapter.handle_incoming_message(payload)))
}

// 4. Wire in main.rs
.nest("/api/teams", crate::channels::teams::router(app_state.clone()))
```
