    OpenAPI reusable responses: Added components.responses for `Problem400`, `Problem404`, and `Problem422`; v1 routes reference these consistently.

Meal planner backend
## Structure
- `main.py`: FastAPI app with all HTTP endpoints.
- `db.py`: aiosqlite connection + schema bootstrap across subpackages.
- Domain packages with models and persistence:
- `products/` (db, scrapers for Woolworths/Coles)
- `ingredients/`
- `recipes/` (db, scraping)
- `meals/`
- `persons/`
- `shopping/`
- `tests/`: unit and API tests with sample HTTP fixtures.
## Getting started
Install packages
```
pip install -r ./requirements.txt
```
Run API (dev)
```
uvicorn main:app --reload
```
Run tests
```
python -m unittest -q
```
## Tooling
This repo includes baseline configs in `pyproject.toml`:
- black (format)
- ruff (lint)
- mypy (type check)
Optional commands (install these locally first):
```
ruff check .
black .
mypy .
```
## Environment variables
- DOOF_DB: Path to sqlite database (default: `./data/doof.sqlite`)
- DOOF_PORT: Port the server listens on when containerized; align Dockerfile `EXPOSE` accordingly.
## OpenAPI schema
- Generate the schema artifact used by the frontend and CI checks:
```
python scripts/export_openapi.py
```
This writes `openapi.json` to the repo root. Versioned endpoints live under `/api/v1`, legacy under `/api` (deprecated with `Deprecation` header).
## Schema lint/diff (manual)
Optionally, lint and compare schemas locally using Node tools:
```
npx -y @stoplight/spectral-cli lint openapi.json
npx -y openapi-diff --fail-on-changed --fail-on-incompatible path/to/baseline.json openapi.json
```
Keep a `baseline.json` on release branches to detect breaking changes.
