 ## OpenAPI contract
 
-- `packages/docs/openapi.json` is an ignored build artifact generated by `pnpm den:contract` and linted with `pnpm api:lint`. CI generates OpenAPI/SDK from source and fails on generation/type errors, Spectral errors, or warnings above `.spectral-baseline.json`. Hosted docs read the same normalized public contract from `/openapi.json?public=1`.
+- `packages/docs/openapi.json` is an ignored build artifact generated by `pnpm den:contract` and linted with `pnpm api:lint`. CI generates OpenAPI/SDK from source and fails on generation/type errors, Spectral errors, or warnings above `.spectral-baseline.json`. Hosted docs read the same normalized public contract from `/openapi.json?public=1`; `.github/workflows/refresh-api-docs.yml` rebuilds them once production serves a contract change.
 - Every route registration carries a `describeRoute()` with `summary`, `tags`, `security` and `responses`; conventions and documented exceptions are in [`docs/api-style.md`](../../../docs/api-style.md).
