- Fixed a test-isolation bug that made `EmbeddingManagerConcurrentTest::test_concurrent_store_embedding_no_duplicates` fail intermittently under `pytest -n` (xdist). `TestMoveDocumentAsync.setUp` (`opencontractserver/tests/test_move_document_tool.py`) and `TestCorpusFileToolsAsync.setUp` (`opencontractserver/tests/test_corpus_file_tools.py`) disconnected `process_doc_on_create_atomic` and then **unconditionally reconnected it in a `finally` block** — overriding the session-scoped `disable_document_processing_signals` fixture (`conftest.py`) and leaving the create signal connected for every later test sharing the same xdist worker. A subsequent `TransactionTestCase` that commits a `Document` (e.g. the embedding concurrency test) then fired real ingestion against absent media and errored. Both `setUp`s now rely on the conftest fixture and no longer touch the signal.
