## Documentation Standards Applied

All docstrings follow Google-style format with:

### Structure
```python
"""One-line summary.

Longer description explaining what the function does, including any important
context about behavior or side effects.

Args:
    param1 (Type): Description of param1.
    param2 (Type | None): Description of param2 with type alternatives.

Returns:
    ReturnType: Description of what is returned, including nested structures.

Raises:
    HTTPException: 400 if condition, 401 if authentication fails, 403 if forbidden,
        404 if not found, 500 if server error.
"""
```

### Key Elements

1. **Args Section**
   - Parameter name with type annotation
   - Clear description of parameter purpose
   - Default values and optional flags noted

2. **Returns Section**
   - Full return type with nested structure details
   - Description of response format
   - Notes on computed fields or post-processing

3. **Raises Section**
   - All HTTP status codes documented
   - Conditions that trigger each exception
   - Grouped by logical status code meaning

## Next Steps

1. Run `interrogate` to verify 100% documentation coverage
2. Integrate into CI/CD pipeline for enforcement
3. Monitor for new functions requiring docstrings
4. Update batch 3 (remaining router files) with same standards
