 reproducible archive do not close this gate. Prioritize measured K kernel cost
 and retain queue/synchronization checks; postpone further M/FP8 optimization.
 The user's approximately 80+ FPS with FSR4 is not a captured same-scene control.

 ADLX mean usage **93.183%**, core clock **3124.667 MHz** and board power
 **316.717 W**. The user identified the previous 63% reading as Task Manager,
 which is distinct from ADLX's device-wide metric. This capture places GPU kernel cost
 at the center of the next K investigation, while retaining queue measurements.

 Native replay benchmarks now compare fresh exact allocations before timing,
 support event/dispatch profiling and paired batches, retain independent host
 completion intervals, and reject invalid or incomplete timings. Eleven K
