"""Phase 13 sites 3+4 + SS 6: index_file batched migration.

index_file has 3 sites:
- Site 3 (BC at L247): try: mtime = os.path.getmtime(full_path); except Exception: return
- Site 4 (BC at L261): try: with open(full_path, ...) as f: content = f.read(); except Exception: return
- Site 6 (SS at L255): try: res = self.collection.get(...); ...; except Exception: pass

All 3 follow similar patterns: try/except + early return or pass.
