Comprehensive documentation of:
- Create Library 500 error bug and fix
- Root cause analysis (type mismatch in context extraction)
- Testing issues discovered (poor error reporting, mock vs real tests)
- Test improvements implemented
- Tomorrow's 5-phase action plan for API reliability
- Complete endpoint checklist for testing
- Correct vs incorrect code patterns
- Success criteria for "rock solid" API
Reference document for tomorrow's comprehensive API review session.
- Add explicit status code check (require.Equal 201)

- Provide clear error message with actual vs expected status
Now if CreateLibrary returns 500, test will clearly show:
"Failed to create library: expected 201, got 500"
Instead of vague "Library ID is empty" message that hid the 500 error.
- Use c.Get("user").(database.Users) instead of c.Get("user_id").(string)
- Extract userUUID from user.ID.Bytes ([16]byte)
- Properly convert to pgtype.UUID for service layer
- Remove unnecessary uuid.Parse call
This fixes 500 Internal Server Error when creating libraries via API.
The JWT middleware sets user as database.Users struct, not string.
