The newest release with wheels for every supported platform: 0.38.0 publishes none for x86_64 Linux or Windows. The zero-coverage FTS scan path is still broken at 0.37.1, so the guard, prevention and repair carry unchanged. ensure_indexes names the index it declares, keeping replace deterministic on 0.38+, where an unnamed create_index builds a suffixed sibling instead of replacing a different-typed index. An invalid search filter raises ValueError.
