On Chinese-language Windows, test_strict_soft_sentinel_inspection_failure_closes_descriptor fails because the OS returns [WinError 6] 句柄无效。, which does not match its hard-coded English messages. The file descriptor is correctly closed.

Check OSError.errno == EBADF directly with pytest.raises(check=...), replacing the message match and subsequent errno assertion. This retains the closed-descriptor check regardless of the OS language and follows the predicate style used elsewhere in the suite.

Validation on Windows / Python 3.13:

• The original complete suite has only this failure: 2414 passed, 544 skipped, 1 failed. The individual test reproduces it independently.
• The final complete suite passes: 2415 passed, 544 skipped.
• The strict-soft module passes (40 passed, 2 skipped); Ruff check/format and git diff --check pass.
