Objective

Validate API contracts between frontend TypeScript and backend Python to prevent breaking changes.

Expected Outcome

• TypeScript types generated from Python models
• Contract validation tests
• Breaking change detection
• Type safety across stack

Files to Create

2. /frontend/src/lib/types/generated/ - Generated types

Implementation Approach

1. Create Python script to read Pydantic models
2. Generate corresponding TypeScript interfaces
3. Add validation tests
4. Detect breaking changes in CI

Success Criteria

• Types generated from Python
• Frontend uses generated types
• Breaking changes detected
• Type safety enforced
