- split.ProvenanceTracker: Check _unified_manager.track_chunk() return value and fall back to legacy storage when None is returned (storage failure)
- split.ProvenanceTracker: Initialize legacy stores (_provenance_store and _chunk_registry) unconditionally in __init__ so legacy fallback storage works safely even when initialized with use_unified=True
- split.ProvenanceTracker: Update get_provenance() to check legacy storage when no record is found in unified storage, ensuring fallback-tracked chunks remain retrievable
- SourceTracker: Change track_sources_batch() condition from if entry is not None: to if ok: to respect the boolean return contract (-> bool) of track_entity_source(), track_property_source(), and track_relationship_source()
- Tests: Add regression test test_unified_tracking_returns_none_triggers_fallback and update test_track_sources_batch_failure_not_counted to test boolean failure return_value=False
- Robust ID extraction in CentralityCalculator, CommunityDetector, and ConnectivityAnalyzer
- Support for direct Entity objects and dictionaries as node identifiers
- Improved Entity hashability in utils/types.py
- Added integration test to verify fix and prevent regression
- Fix infinite recursion in semantica/conflicts/methods.py by removing redundant registration
- Update 04_Conflict_Resolution_Strategies.ipynb to use correct API
- Add unit tests for conflicts module in tests/conflicts/test_conflicts.py
- Add __init__.py files to tests/ and tests/conflicts/ for package structure
