## 🎯 Key Accomplishments

### 1. Complete REST API for Scan Management

All CRUD operations implemented with comprehensive error handling:

```bash
# Trigger scan
POST /api/scans
{"config_file": "/app/configs/example.yaml"}
→ {"scan_id": 42, "status": "running"}

# List scans (paginated)
GET /api/scans?page=1&per_page=20&status=completed
→ {"scans": [...], "total": 42, "page": 1, "pages": 3}

# Get scan details
GET /api/scans/42
→ {full scan with all relationships}

# Poll status
GET /api/scans/42/status
→ {"status": "running", "started_at": "...", "completed_at": null}

# Delete scan
DELETE /api/scans/42
→ {"message": "Scan 42 deleted successfully"}
```

### 2. Asynchronous Scan Execution

## 🔧 Technical Implementation Details

### Service Layer Architecture

**ScanService** (`web/services/scan_service.py`) - 545 lines:
- `trigger_scan(config_file, triggered_by, schedule_id)` - Create scan record and queue job
- `get_scan(scan_id)` - Retrieve complete scan with all relationships (eager loading)
- `list_scans(page, per_page, status_filter)` - Paginated list with filtering
- `delete_scan(scan_id)` - Remove DB records and files (JSON, HTML, ZIP, screenshots)
- `get_scan_status(scan_id)` - Poll scan status for real-time updates
- `_save_scan_to_db(report, scan_id, status)` - Persist scan results
- `_map_report_to_models(report, scan_obj)` - Complex JSON→DB mapping

**SchedulerService** (`web/services/scheduler_service.py`) - 220 lines:
- `init_scheduler(app)` - Initialize APScheduler
- `queue_scan(config_file, scan_id, db_url)` - Queue immediate scan execution
- `add_scheduled_scan(schedule)` - Placeholder for Phase 3 scheduled scans
- `remove_scheduled_scan(schedule_id)` - Remove scheduled jobs
- `list_jobs()` - List all scheduler jobs
- `shutdown()` - Graceful shutdown

### Background Job Execution

**Scan Job** (`web/jobs/scan_job.py`) - 130 lines:

```python
def execute_scan(config_file, scan_id, db_url):
    """Execute scan in background thread."""
    # 1. Create isolated DB session
    engine = create_engine(db_url)
    Session = sessionmaker(bind=engine)
    session = Session()

    try:
        # 2. Update status to running
        scan = session.query(Scan).get(scan_id)
        scan.status = 'running'
        scan.started_at = datetime.utcnow()
        session.commit()

        # 3. Run scanner
        scanner = SneakyScanner(config_file)
        report, timestamp = scanner.scan()
        scanner.generate_outputs(report, timestamp)

        # 4. Save to database
        scan_service = ScanService(session)
        scan_service._save_scan_to_db(report, scan_id, status='completed')

        # 5. Update timing
        scan.completed_at = datetime.utcnow()
        session.commit()

    except Exception as e:
        # 6. Mark as failed
        scan.status = 'failed'
        scan.error_message = str(e)
        scan.completed_at = datetime.utcnow()
        session.commit()
        logger.error(f"Scan {scan_id} failed: {e}")

    finally:
        session.close()
```

### Database Mapping Strategy

Complex JSON structure mapped to normalized schema in specific order:

1. **Scan** - Top-level metadata
2. **Sites** - Logical grouping from config
3. **IPs** - IP addresses per site
4. **Ports** - Open ports per IP
5. **Services** - Service detection per port
6. **Certificates** - SSL/TLS certs per HTTPS service
7. **TLS Versions** - TLS version support per certificate

**Key Technique:** Use `session.flush()` after each level to generate IDs for foreign keys

### Authentication Flow

```
┌──────────────────────────────────────┐
│ 1. User visits /dashboard            │
│    (not authenticated)                │
└───────────┬──────────────────────────┘
            │
            ▼
┌──────────────────────────────────────┐
│ 2. @login_required redirects to      │
│    /login                             │
└───────────┬──────────────────────────┘
            │
            ▼
┌──────────────────────────────────────┐
│ 3. User enters password               │
│    POST /auth/login                   │
└───────────┬──────────────────────────┘
            │
            ▼
┌──────────────────────────────────────┐
│ 4. Verify password (bcrypt)           │
│    - Load password from settings      │
│    - Check with bcrypt.checkpw()      │
└───────────┬──────────────────────────┘
            │
            ▼
┌──────────────────────────────────────┐
│ 5. Create Flask-Login session         │
│    login_user(user)                   │
└───────────┬──────────────────────────┘
            │
            ▼
┌──────────────────────────────────────┐
│ 6. Redirect to /dashboard             │
│    (authenticated, can access)        │
└──────────────────────────────────────┘
```

### Error Handling Architecture

**Content Negotiation:**
```python
def render_error(status_code, error_type, message):
    """Render error as JSON or HTML based on request."""
    # Check if JSON response expected
    if request.path.startswith('/api/') or \
       request.accept_mimetypes.best == 'application/json':
        return jsonify({
            'error': error_type,
            'message': message
        }), status_code

    # Otherwise return HTML error page
    return render_template(f'errors/{status_code}.html',
                          error=error_type,
                          message=message), status_code
```

**Request ID Tracking:**
```python
@app.before_request
def before_request():
    """Add request ID and start timing."""
    request.id = uuid.uuid4().hex[:8]
    request.start_time = time.time()

@app.after_request
def after_request(response):
    """Add timing and request ID headers."""
    duration_ms = int((time.time() - request.start_time) * 1000)
    response.headers['X-Request-ID'] = request.id
    response.headers['X-Request-Duration-Ms'] = str(duration_ms)
    return response
```

## 🎓 Lessons Learned

### What Went Well

1. **Service Layer Architecture** - Clean separation between API endpoints and business logic made testing much easier

2. **Background Job Integration** - APScheduler worked perfectly for async scan execution without needing Redis/Celery

3. **Database Mapping Strategy** - Processing in order (sites → IPs → ports → services → certs → TLS) with `flush()` after each level handled foreign keys elegantly

4. **Test-First Approach** - Writing tests for Steps 1-3 before implementation caught many edge cases early

5. **Comprehensive Documentation** - Detailed PHASE2.md plan made implementation straightforward and prevented scope creep

### Challenges Overcome

1. **SQLite Concurrency** - Initial database locking issues with concurrent scans
   - **Solution:** Enabled WAL mode, added connection pooling, increased busy timeout to 15s

2. **Complex JSON→DB Mapping** - Nested JSON structure with many relationships
   - **Solution:** Created `_map_report_to_models()` with ordered processing and `flush()` for ID generation

3. **Background Thread Sessions** - SQLAlchemy session management in threads
   - **Solution:** Create isolated session per thread, pass `db_url` to background job

4. **Content Negotiation** - API and web requests need different error formats
   - **Solution:** Check `request.path.startswith('/api/')` and `Accept` header

5. **Request ID Correlation** - Difficult to correlate logs across request lifecycle
   - **Solution:** Add RequestIDLogFilter with UUID-based request IDs in logs and headers

### Technical Decisions

1. **APScheduler over Celery** - Simpler deployment, sufficient for single-user use case
2. **Session Auth over JWT** - Simpler for Phase 2, token auth deferred to Phase 5
3. **SQLite WAL Mode** - Better concurrency without switching databases
4. **Bootstrap 5 Dark Theme** - Matches existing HTML report aesthetics
5. **Pytest over unittest** - More powerful fixtures, better parametrization
