CI run 25805598433 failed across all 9 OS×Python cells:
- TestToolEndpointsLive / TestAnthropicMessagesStreaming /
  TestReviewFixesVllmAnthropicLive ModuleNotFoundError: fastapi (CI does
  not install [serve] extra) → autouse fixture pytest.importorskip()
- test_load_pretokenized_dataset_rejects_symlink:
  load_pretokenized_dataset called datasets.load_from_disk on the symlink
  target before the lstat check ran → moved the lstat + S_ISLNK check
  to the entry of the helper so symlinks reject before any load attempt
- test_redact_exc_message_handles_windows_paths: hardened _redact_exc_message
  to strip both POSIX absolute paths and Windows-style paths regardless
  of host platform

Local pytest tests/test_v0537.py: 112 passed, 7 skipped.
