pyproject.toml (1)

458-458: Consider setting timeout_method = "thread" for harder CI-stall prevention.

If the intent is to reliably stop hangs in native/CUDA paths, explicitly using thread is usually more robust than default signal-based interruption.

 markers = "run"
 timeout = 1800
+timeout_method = "thread"
