    main.py          # FastAPI() + middleware + router include
    config.py        # pydantic-settings Settings

  .env.example       # committed template
  .venv/             # local-only, not committed

Virtual environment (required)

cd api
python3 -m venv .venv          # use /opt/homebrew/bin/python3.12 if system python < 3.10
source .venv/bin/activate
pip install -r requirements.txt

Never pip install without the venv active. Never install deps globally.

Running

source api/.venv/bin/activate
uvicorn app.main:app --reload --host 127.0.0.1 --port 8000

Database & migrations

Configuration comes from environment variables (DATABASE_URL, etc.) loaded via Settings in app/config.py.
Schema changes are always Alembic migrations — never raw DDL, never SQLAlchemy create_all in app code.
Create a migration with alembic revision --autogenerate -m "<message>", review the generated file, then alembic upgrade head.

Endpoints

Declare routes on an APIRouter(prefix="/<resource>", tags=["<resource>"]) in app/routers/<resource>.py.
Use response_model= so OpenAPI stays accurate.
Inject DB sessions via Depends(get_db); never reach for SessionLocal() in handlers.
Raise HTTPException with explicit status_code for error paths.

Validation

Pydantic schemas in schemas.py are the source of truth for shape + validation.
Enums (e.g. Condition) live as str, Enum classes so they render as string enums in OpenAPI.

CORS

Allowed origins are driven by CORS_ALLOW_ORIGINS in .env (comma-separated) and applied in main.py.
