2. Creates auth middleware
3. Updates routes
4. Adds JWT handling
5. Creates user model
6. Writes tests
7. Updates documentation
8. Shows you diffs for approval
        

Your role: Supervisor, not coder

Amazon Q:
- Enables encryption (KMS)
- Blocks public access
- Enables versioning
- Configures lifecycle policies
- Sets up access logging
- Adds bucket policy
- Recommends VPC endpoint
- Estimates costs
        

3. Multi-IDE Support
