Semantic Search Pipeline Repair
Bugfix release that repairs the semantic search pipeline. Six of seven natural-language queries returned zero results on real codebases due to accumulated orphan rows in the sqlite-vec virtual table. v4 → v5 migration runs automatically on first start and cleans existing residue.
Correction`chunks_vec` orphan rows — sqlite-vec virtual tables don't honor `FK ON DELETE CASCADE`, so every prior `INSERT INTO chunks` (after the delete-then-reinsert pattern in `insert_chunks`) left the previous chunk's vector behind. Over many reindex cycles those orphans dominated the KNN top-k and silently broke semantic search. All delete paths (`insert_chunks`, `delete_file`, `clear_all_data`, `check_and_prepare_for_reindex`) now purge `chunks_vec` in the same transaction. New integration test `vec_invariant` pins the contract
CorrectionGhost files with absolute paths — the legacy `path.strip_prefix(root).unwrap_or(path)` pattern silently fell through to absolute paths when `strip_prefix` failed, leaving duplicate rows in `files`. Replaced everywhere with `paths::to_relative_string`, which warns instead of failing silently
Correction`pub use` re-exports not extracted — `parse_rust_use_path` stripped `"use "` first, so any line starting with `pub` (or `pub(crate)`, `pub(super)`, `pub(in path)`) returned `None`. This broke `semantiq_deps` on every Rust `lib.rs`, since those files are mostly re-exports
Correction`symbol_kind` missing in semantic search results — `search_semantic` hard-coded `symbol_kind: None`, so output showed `Symbol: foo (unknown)` even though the kind was already in the database. Now batch-fetched per file and propagated
FonctionnalitéSchema v4 → v5 migration — purges existing `chunks_vec` orphans and ghost rows with absolute paths (POSIX, Windows drive paths, UNC). Wrapped in a single transaction for crash safety. Visible at startup as e.g. `Migrating schema v4 -> v5 (a): purged N orphan rows`
Fonctionnalité`IndexStore::count_orphan_chunk_vectors()` for diagnostics — the `RetrievalEngine` calls it at startup and emits a `WARN` if the invariant is broken
AméliorationNew `paths::to_relative_string` helper in `semantiq-index` — tries a literal `strip_prefix` first and only canonicalizes on the fallback path, keeping the hot indexing loop free of realpath syscalls
Amélioration~6× lower latency on natural-language queries via the MCP server now that the KNN top-k surfaces real chunks instead of zombie zero-vectors (28–93 ms vs 78–123 ms previously, on the reference repo)
