32 iterations of H2D-then-D2H copies of a 4 MiB buffer, each verified with a full element-wise comparison. Exercises sustained host<->device transfer and the stream queue-submission path; any dropped or reordered byte fails. GPU required. Verified on MI300X (98 assertions).

Summary
HRX bring-up regression test (tag
[nightly]) paired with ROCm/hrx-system#56.32 H2D/D2H roundtrips with data-integrity checks; each rings the AQL queue doorbell, so on a USER-kind-doorbell runtime (nightly MI300X) this repeatedly exercises the
hsa_signal_store_screleasefallback that replaced the faulting raw MMIO store. Verified on MI300X (98 assertions).Draft: pairs with the draft fix #56. Mark ready once it lands.
