+`native_replay_probe` reads upstream `manifest.txt`/`args.bin`/`alloc-N.bin`,
+relocates allocation pointers, runs the module's prep and main kernels, and
+saves GPU allocations for the existing `pwin_check`/`pwin_model` references.
+No NVIDIA DLL, PTX or weights are needed for these synthetic fixtures.
+Each fixture enables nonzero projections, attention, MLP and the layer's
+embedding/merge/head operations; it covers one 8x8 window with sparse weights.
+It does not replace validation with real network weights, multiple windows,
+shifted borders, textures or complete DLSS output.
