Temporary debugging change: cut the linux and windows pull-request matrices down to a single Python 3.12 + CUDA 12.9.1 row each so the TestIpcReexport hang on r595-driver runners reproduces quickly without also burning compute on unrelated configurations. The nightly matrices are intentionally untouched. Revert before merging.

Wire the existing SETUP_SANITIZER gate behind a literal `false &&` so every PR test job exports SETUP_SANITIZER=0 and SANITIZER_CMD=, which makes run-tests invoke pytest directly instead of under compute-sanitizer. Pairs with the matrix trim in this branch to test the hypothesis that the TestIpcReexport hang on r595-driver runners is specific to running pytest under compute-sanitizer. Revert before merging.

Summary
Temporary debugging PR. Cuts the
pull-requesttest matrix inci/test-matrix.ymldown to a single Python 3.12 + CUDA 12.9.1 row perplatform/arch (linux-64 L4, linux-aarch64 A100, win-64 L4) so the
TestIpcReexport::test_main[DeviceMR]hang seen on the r595-driverrunners (e.g. https://github.com/NVIDIA/cuda-python/actions/runs/26162055334)
reproduces fast without burning compute on configurations we already
know are green. The
nightlymatrices are intentionally untouched.This is not intended to merge; it exists only to drive CI iterations
while we investigate the hang. The patch is fully self-contained and
reverts cleanly.
Test plan
TestIpcReexport::test_main[DeviceMR]hang (or surfaces a realfailure once a fix lands).
trimming the matrix didn't break the workflow plumbing).
