## Summary - reconstruct foreign Arrow Map schemas from their single sanitized entries field - reject malformed Map types with anything other than one child - preserve the complete Map schema and `keysSorted` value through empty-table creation and IPC round trips across Arrow 15–18 ## Testing - `./node_modules/.bin/jest --runInBand __test__/arrow.test.ts __test__/sanitize.test.ts` - `pnpm lint` - `pnpm build` - `pnpm run docs` Fixes #2337
