- PathFinder.bfs_shortest_path() and dijkstra_shortest_path() gain a
directed: bool = True parameter. When False, a temporary undirected
view (graph.to_undirected()) is used for traversal only; the original
directed edges are preserved and returned in the response.
- _make_undirected_view() helper added to PathFinder; falls back safely
for non-NetworkX graph types.
- GET /api/graph/node/{id}/path exposes ?directed=false query param.
- PathResponse gains a directed: bool field echoing the mode used.
- Route now returns 404 on empty path (previously returned 200 with
path: []).
- 21 new tests: 12 unit (TestBidirectionalPathFinding) + 9 API-level
(TestBidirectionalPathRoute). All 120 tests pass.
- CHANGELOG updated under [Unreleased].

- Add TemporalGraphRetriever to context_retriever.py (no new file per project convention)
- Drop-in wrapper for ContextRetriever; filters related_entities/related_relationships
via reconstruct_at_time(); at_time=None is a true passthrough
- Returns new RetrievedContext objects (no in-place mutation)
- Graceful ImportError if temporal modules unavailable
- Add at_time + header_template to ContextRetriever._generate_reasoned_response()
and query_with_reasoning()
- Temporal header prepended to LLM context block only when at_time is set
- Naive datetimes normalised to UTC before formatting
- Header built with str.replace (not .format) to prevent format-string injection
- Add TemporalQueryRewriter + TemporalQueryResult to semantica/kg/
- Regex-only (default) and LLM-assisted extraction modes
- Resolves temporal phrases via TemporalNormalizer (deterministic, zero LLM)
- Word-boundary guards on intent keywords; year fallback for noun-phrase dates
- Never calls reconstruct_at_time — extraction only
- Export TemporalGraphRetriever from semantica.context
- Export TemporalQueryRewriter, TemporalQueryResult from semantica.kg
- Add 99 tests across two new test files
- tests/context/test_temporal_retriever.py (56 tests)
- tests/kg/test_temporal_query_rewriter.py (43 tests)

- 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
