 K now renders real menu frames and M renders a saved gameplay level with
-GPU NaN/Inf checks. K also passes 3840x2160 output and M passes 1920x1080.

+The user reports 49-51 FPS for K in the measured scene after the command-hook

 development package; no NVIDIA proprietary DLL is included.
 
 Build the shim/diagnostics, corrected ZLUDA, K/M native objects and patched
 OptiScaler using the scripts in `scripts/windows`, then run:

 The package pins TheRock 10.2.0a20260929 because its Windows external-memory
 mapping lifetime passes the repeated import/release test. Stable HIP 7.2 has
 a reproduced mapped-view leak; see `docs/windows-rdna4-port.md` for the source
 fix, exact dependency versions, validation and complete build commands.
+The ZIP contains only manifest-listed files, including a snapshot of committed
+d4r source. Private NVIDIA-derived objects, caches and diagnostic captures are
+excluded. Original FP8 M and the optional hardware-packing variant pass strict
+replay/network tests but do not establish a full-network speedup, so the game
+package retains its FP16-equivalent M baseline.
