## Cause The Arrow type sanitizer handled Utf8 and Binary but omitted LargeUtf8 and LargeBinary, so Arrow tables from another Arrow installation failed schema sanitization before reaching LanceDB. ## Fix Reconstruct both large Arrow types during sanitization. Regression tests cover createTable and add with Arrow 15–18 and adding a LargeBinary Arrow column to a blob table. ## Validation - Confirmed the new table test failed before the fix with `Unrecognized type id in schema: 20` on all four Arrow versions. - The table, sanitizer, and Arrow Jest suites passed: 604 tests. - `pnpm lint`, `pnpm build`, and `pnpm run docs` passed. Fixes #4266 <!-- lance-gatekeeper-fix:v1 agent=1090de3c0ddeca587956632b79f0193c generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com>
