### Purpose Indexed vector search can lose matching rows when a partition column's position in the table schema differs from its position in the partition row. For example, filtering `pt` in a schema `id, embedding, pt` can return no results when an exact scalar index filter selects a source plan. ### Brief change log Remap the partition predicate from partition-row positions back to complete table-schema positions before collecting allowed source row IDs. Add regression coverage for single and batch vector searches in fast, full and detail modes, checking both scores and materialized rows. ### Tests - The 6 new regression cases fail against main `96e06d764365b59c9895a45692819efccf209b23` and pass with this change. - `cargo test -p paimon --lib table::de_vector_read::tests`: 56 passed. - Python binding `test_vector_search.py`, using a wheel built from this commit: 15 passed. - `cargo fmt --all --check` and `git diff --check`: passed. ### API and Format No public API or storage-format changes. ### Documentation Bug fix; no documentation changes required. -- This is an automated message from the Apache Git Service.
