## Summary - Adds a LanceDB regression for stable row IDs, scattered deletes, IVF_RQ, and default index optimization. - Verifies optimization completes and preserves the expected live-row count. ## Root cause Lance 3.0.1 built the stable-row-ID address list by dropping deleted IDs while retaining the original ID list. The subsequent positional zip misaligned IDs and addresses, so vector partition joins requested deleted rows and failed with batch.num_rows() != chunk.len(). Lance PR https://github.com/lance-format/lance/pull/7704 corrected the generic filter, and the LanceDB dependency currently pinned on main contains that correction. ## Fix Add regression coverage at the Rust Table optimize surface using the IVF_RQ configuration from the report. This locks the upstream correction into the LanceDB workflow that originally crashed. ## Validation - cargo fmt --all -- --check - cargo test --quiet --features remote -p lancedb table::optimize::tests (14 passed) - cargo check --quiet --features remote --tests --examples - cargo clippy --quiet --features remote --tests --examples -p lancedb Fixes #3330 <!-- lance-gatekeeper-fix:v1 agent=4c2c25373942aab9ba9f7444977de7e3 generation=1 --> Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com>
