## Summary - add regression coverage for an IVF_RQ index created through the Lance Python API and consumed through LanceDB - verify a fresh LanceDB handle can list and query the externally-created index ## Root cause Lance 4.0.0-beta.5 could serialize `rotate_mat_position` as null, while the Lance 2.0.0 reader used by LanceDB 0.29.2 required a `u32`. Upstream Lance fixed the incompatible IVF_RQ metadata handling and index versioning, and the current LanceDB dependency includes that repair. LanceDB was missing coverage for the reported mixed-API workflow, allowing the compatibility regression to go undetected. ## Validation - `cd python && uv run --extra tests pytest python/tests/test_index.py -q` (24 passed) - `uv run --project python --extra dev ruff format .` - `uv run --project python --extra dev ruff check .` - `uv run --project python --extra dev ruff format --check python/python/tests/test_index.py` - `uv run --project python --extra dev ruff check python/python/tests/test_index.py` Fixes #3092 <!-- lance-gatekeeper-fix:v1 agent=7d8c849bd8421be65d32355c42a60b8a generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com>
