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.
