## Source of truth

The artifacts in this repository are the spec. Edit `config.schema.json`,
`precisions.json` and `MODEL_CARD.md` here, and treat them as authoritative
for every published `config.json` and `README.md`.

## 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.
