+Production K/4K with private output stores completes 9982 frames and 9982

+then localizes contention to the shared command-list routing map. A per-thread
+weak lookup cache bypasses that mutex for repeated calls, invalidating on map
+mutations to preserve Reset/final Release/address reuse. Queue and per-list
+synchronization remain. The regression resets/re-splits the same object twice
+per iteration with different root constants and verifies both GPU outputs.
+All sixteen CTest gates pass. The cached game run completes 4770 K/4K frames
+and 4770 finite GPU scans, zero failures/CPU image copies/aged outputs. The user
+reports 49-51 FPS and 53% GPU usage. Aggregated sampled access/capture time
+falls from 977.528 to 233.606 ms/s across threads; it includes parallel lock
+waits and must not be treated as serial frame time. Median recording interval
+is 19.473 ms. `-ProfileCommandHooks` is optional and off during ordinary play.
+Detailed scope and timings are in [windows-performance.md](windows-performance.md).
