Release Notes

Performance

• Composite index (repo_name, fqn) on :Entity — the CONTAINS
  auto-link query no longer degrades to O(n²) per-row label scans on
  every entity in the repository. Large repos (~50K entities) no
  longer timeout at the end of indexing. The index is created with
  IF NOT EXISTS so it migrates automatically into existing
  deployments.

Internal

• Extracted index_statements() from ensure_indexes() for unit
  testing (same pattern already used by build_contains_auto_link_cypher()).
• Added unit tests covering the new composite index, idempotency of
  IF NOT EXISTS, and preservation of all existing index statements.
• Added integration test (#[ignore]) that verifies the index appears
  in SHOW INDEXES and that EXPLAIN of the auto-link Cypher succeeds.
• Added e2e regression script (run_contains_autolink_index_e2e.sh)
  with a synthetic Java fixture of 5,200 entities, verifying index
  presence, plan index-seek, correct CONTAINS edge counts, and a time
  budget canary against O(n²) regression.
