Documentation Style

All docs follow the structure of backend/docs/websockets.md:

• What it is - Feature overview
• Where it lives - Code map with file paths
• How it works - Architecture and flow
• How to use it - Practical examples
• Configuration - Environment variables and settings
• Extending / modifying - Extension points
• Troubleshooting - Common issues
• Security considerations - Security notes
• Related docs - Cross-references

Gaps Found

1. Email sending: Password reset tokens are logged in development but email sending is not implemented (noted in authentication.md).
2. Background jobs: No background job system found (not included in docs).
3. File uploads: No file upload system found (not included in docs).
4. Testing: No testing strategy documented (no test files found in the structure).

All documentation is grounded in the codebase. No endpoints, env vars, routes, or behaviors were invented. All examples reference actual code paths and existing functionality.

The documentation is ready for use and follows the template's existing documentation style.
