 - **Do NOT check in UMD build artifacts**: Files matching `*.umd.js` in `docs/dist/v1/` are build outputs and should not be committed in PRs
+- **Do NOT edit `docs/schema/idoc_v1.d.ts` directly**: This file is generated from `packages/schema-doc/src/`. Edit the source files in the schema-doc package instead
