+       session (a deferred flush executed with the client's channels valid, dropped its
+       queued launch release, and froze it in the tracker wait); GR entries whose decode
+       sees QMD words but builds no launch candidate are held and re-captured instead of
+       consumed silently; a failed device-destination copy holds its entry instead of
+       silently dropping the data; pool releases apply at fresh-pin time instead of

+       spans whose first page resolves nothing hold the launch (bounded) instead of
+       forwarding stale operands; device-destination copies answered only by a page-table
+       walk wait (bounded 3 s) for a pin. `victory_mail`, `victory_matmul` and `smiley`
+       are green on every boot of the wave, including the user's exact repro and mail as
+       the eighth client of a used boot. streams2/memset2d/saxpy no longer wedge - they
+       now fail fast (~35-60 s) on the remaining data class: an H2D into a device buffer
