Consolidates the remaining #994 fixes into this PR so it can fully close
the issue, per maintainer request.
From #1005 (yzxcj797):
- EmbeddingGeneratorWithProvenance.__getattr__ self-recursion guard:
accessing self._generator via attribute syntax re-entered __getattr__
forever when _generator was absent (failed __init__, pickle/copy probes
like __deepcopy__). Private-name lookups now raise AttributeError.
- 4 regression tests in TestMethodDispatchRecursion: default dispatch no
longer self-recurses for generation/text, a user-registered custom
method still takes precedence, and a bare provenance wrapper raises
AttributeError instead of RecursionError.
(The methods.py identity guards from #1005 are already present here.)
From #1006 (yzxcj797):
- doctor gains two embedding backend checks, "Embeddings
(sentence-transformers)" and "Embeddings (fastembed)". Default is a
cheap import+version check (uninstalled backend now reports fail with a
pip hint instead of invisible). --deep-embeddings (or
SEMANTICA_DOCTOR_DEEP_EMBEDDINGS=1) instantiates via TextEmbedder and
embeds a probe, catching backends that import cleanly but cannot load
(the #994 failure mode) via the hash-fallback-active signal.
_DeepEmbeddingFailure marks post-import runtime/model-load failures so
they get a remediation hint instead of a misleading pip-install hint.
- 7 tests in TestDoctorEmbeddings and TestDoctorEmbeddingHintsAndEnv.
Validation:
- tests/test_cli_commands.py: 237 passed (7 new)
- tests/test_embedding_providers.py: 9 passed (4 new)
- AST parse + import of all four modules OK
- 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
