Verified that BanGUI's codebase is fully compliant with the constraint that
Pydantic validators must not execute at import time or have side effects.
Changes:
- Architekture.md § 2.1: Added explicit 'No I/O or Side Effects' constraint
for model validators, explaining why this prevents circular dependencies
- Backend-Development.md: Enhanced validator documentation with subsection
on import-time execution, including wrong/correct examples
- Tasks.md: Marked '[Backend] Pydantic validators execute at import time'
as COMPLETE with verification results and regression prevention guidance
Verification Summary:
✓ Audited 14 model files: no problematic imports or function calls
✓ Import time: 0.159s (fast, no import-time side effects)
✓ Type checking: mypy --strict passes on all models
✓ Unit tests: 17 tests pass (100%)
✓ Correct pattern in use: validation in routers/services, not models
The codebase architecture is sound—no code changes required, only
documentation clarification to prevent future violations.
