The following tests fail on running with the --ignore=tests/csl_runtime option and the environment variable WSE_ARCH=wse3 set:

FAILED tests/spatial_ir/test_task_recycling.py::test_task_recycling_plan_reuses_local_slots - assert 15 > 20
FAILED tests/spatial_ir/test_task_recycling_codegen.py::test_csl_runtime_task_recycling_sample_lowers[task_recycling_merge.sptl] - AssertionError: expected task-ID recycling in generated CSL

FAILED tests/spatial_ir/test_task_recycling_codegen.py::test_csl_runtime_task_recycling_sample_lowers[task_recycling_three_stage.sptl] - AssertionError: expected task-ID recycling in generated CSL

All tests succeed when unsetting the environment variable.
