- Fix _transform_audit_lineage to classify all non-downstream ancestor derivation edges as 'upstream' instead of 'lateral', correcting multi-hop lineage direction in JSON and markdown reports.
- Add GraphSession.set_provenance_storage_path() to explicitly reject conflicting preconfigured storage paths or path mutations after provenance_manager initialization.
- Update create_app() to call active_session.set_provenance_storage_path(prov_path), preventing silent retention of conflicting paths or un-redirectable cached managers.
- Remove unused logging import in app.py.
- Add comprehensive unit tests in test_provenance_manager_wiring.py for upstream edge classification, markdown report grouping, conflicting path rejection, and manager initialization lockouts.
