## Source of truth

The human-readable spec lives at
[`software-mansion/react-native-executorch:MODEL_SPEC.md`](https://github.com/software-mansion/react-native-executorch/blob/main/MODEL_SPEC.md).
Edit that document first; the artifacts here are derived from it.

## Versioning

The schema is referenced by `$schema` from every `config.json` in the
ecosystem. Breaking changes get a new `$id` URL and the old one stays
available so existing files continue to validate.
