Row: KERNEL-QUANT-CIQ-GEMM-ROCM
The cooperative-tile tests in PR #3036 select BIGTILE and SHARE_ACT by environment-variable presence. The production dispatch enables these options only when their value is exactly 1.
At head d295f00, tests/vt/test_backend_cross_device.cpp:3540 and :3665 therefore disagree with the production predicates in src/vt/rocm/rocm_grouped_gemm.hip:2144 and :2162.
For example, WIDE=1, SHARE_ACT=1, BIGTILE=0 selects the Shared kernel, but the tests expect BigTile counters. Explicit zero values must be treated as disabled. The tests must also respect the master WMMA switch.
Repair this in PR #3036. Run the toggle matrix on gfx1200 or gfx1201 and independently mutate the test predicate to prove regression coverage. Static finding confirmed; GPU reproduction remains pending.
