Note
Low Risk
Low risk: only adjusts CI linter test invocation flags to work around an upstream pytest plugin crash on Python 3.14, without changing production/runtime logic.
Overview
Updates
ci/test_custom_linters.pyto disable thepytest-beartype-testsplugin (-p no:pytest_beartype_tests) in both nestedpytest.main(--collect-only)runs.This prevents Python 3.14 nested test collection crashes caused by an upstream beartype/pytest plugin bug, while keeping the linter’s collection-only behavior unchanged.
