# Add a package

1. Create `models/<id>/` with `book/`, `code-study/`, `reference/`, `derived/`, `scripts/`, `Makefile`, `README.md`
2. `scripts/generate_derived.py` must write `derived/summary.json` with:
   `model_id`, `display_name`, `status`, `context_tokens`, `generated_at_utc`, `total_params`, `active_params`
3. Register in `models/registry.json`
4. Offline: stdlib only — no pip, no network in generate/validate
5. `make test` or `python3 run.py test` from `studies/`

Refresh scripts may use curl (online only).
