  "message": "Add fallback implementation of `PyCriticalSection_BeginMutex` for Python 3.13t (#5981)\n\n* Add failback implementation of `PyCriticalSection_BeginMutex` for Python 3.13t\n\n* Add comment for Python version\n\n* Use `_PyCriticalSection_BeginSlow`\n\n* Add forward declaration\n\n* Fix forward declaration\n\n* Remove always true condition `defined(PY_VERSION_HEX)`\n\n* Detect musllinux\n\n* Add manylinux test\n\n* Use direct mutex locking for Python 3.13t\n\n`_PyCriticalSection_BeginSlow` is a private CPython function not exported\non Linux. For Python \u003c 3.14.0rc1, use direct `mutex.lock()`/`mutex.unlock()`\ninstead of critical section APIs.\n\n* Empty commit to trigger CI\n\n* Empty commit to trigger CI\n\n* Empty commit to trigger CI\n\n* Run apt update before apt install\n\n* Remove unnecessary prefix\n\n* Add manylinux test with Python 3.13t\n\n* Simplify pycritical_section with std::unique_lock fallback for Python \u003c 3.14\n\n* Fix potential deadlock in make_iterator_impl for Python 3.13t\n\nRefactor pycritical_section into a unified class with internal version\nchecks instead of using a type alias fallback. Skip locking in\nmake_iterator_impl for Python \u003c 3.14.0rc1 to avoid deadlock during\ntype registration, as pycritical_section cannot release the mutex\nduring Python callbacks without PyCriticalSection_BeginMutex.\n\n* Add reference for xfail message",
