Alex Garcia b00865429b Filter deleted nodes from DiskANN search results and add delete tests ... DiskANN's delete repair only fixes forward edges (nodes the deleted node pointed to). Stale reverse edges can cause deleted rowids to appear in search results. Fix: track a 'confirmed' flag on each search candidate, set when the full-precision vector is successfully read during re-ranking. Only confirmed candidates are included in output. Zero additional SQL queries — piggybacks on the existing re-rank vector read. Also adds delete hardening tests: - Rescore: interleaved delete+KNN, rowid_in after deletes, full delete+reinsert cycle - DiskANN: delete+reinsert cycles with KNN verification, interleaved delete+KNN Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>		2026-03-31 17:13:29 -07:00
