I’ll trace the native CI setup and pytest configuration first, then reproduce the smallest failing case locally. The all-tests-at-setup pattern points to shared process/capture infrastructure rather than 516 independent native-bridge failures.

The shared failure is consistent with a pytest/plugin compatibility break: the macOS lane permits unbounded pytest and pytest-forked upgrades, and CI resolved pytest 9.1.1 plus forked 1.7.5. I’m checking whether the warning originates in the fork wrapper’s inherited capture files and whether our macOS shutdown hook amplifies it before choosing the narrowest fix.

The conflict is now localized: pytest-forked already redirects each child’s stdout/stderr, while pytest’s capture manager redirects them again during resume(). On macOS those displaced fork-wrapper streams are finalized unclosed; the suite’s warnings-as-errors policy converts that plugin-level ResourceWarning into a setup error for every test. I’m removing the redundant capture layer in that lane; forked still retains crash output itself.

The exact native command now completes locally with isolation and pytest capture disabled: 517 passed, 1 expected skip. I’m doing the final workflow syntax and diff checks; the two-test count difference from the reported run reflects the current checkout, not the fix.

Fixed the macOS native CI workflow in test.yml.

Cause: pytest and pytest-forked both captured child streams, producing unclosed-file warnings that warnings-as-errors promoted to setup failures.

Fix: added --capture=no; pytest-forked still captures crash output.

Validation: 517 passed, 1 skipped; YAML and diff checks pass.
