Create router in src/backend/app/routers/ 2. Mount in src/backend/app/main.py 3. Create corresponding Pydantic models 4. Create service layer if needed 5. Add frontend API functions 1. Pick def or async def per endpoint based on whether you call async I/O; do not call blocking I/O from an async def handler. 2.
