_gpu_dxg_r4d_alloc.nx -- SOVEREIGN-GPU ladder R4d ATTEMPT: real UMD-less EXISTINGHEAP allocation on the 5080.
Ground-truth layout (WSL2-Linux-Kernel d3dkmthk.h, VERIFIED against runtime fault-probes: device@0,
alloc_count@44, allocation_info@48 all confirmed; entry priv_drv_data_size@24 fault reconciled):

Try flag combos {standard_allocation, standard_allocation|existing_sysmem} x size {4096}; print ret + the OUT
allocation handle (entry@0) + gpu_virtual_address (entry@40). raw syscalls only. No log writes. license_tier: ORIGINAL
