The proposed change is in extensions/copilot/src/platform/workspaceChunkSearch/node/codeSearch/externalIngestIndex.ts, on the fix/external-ingest-malformed-db-330466-243e02ab1fabbd6 branch. Start by reading the database-opening path and the supplied patch preview. Done means corrupt external-ingest SQLite databases are recreated on open instead of causing a later malformed-database error.
