BZLZHH f2b55b9d2d [Perf] (MG_Remote/Client): the buffer half of resource_respecify stops waiting - its answer is discarded at both call sites - and the measurement says the texture half is where the other 20,611 waits live ...

- The two halves of this row are not the same row. PipeFill.cpp:1105 and :1142 both call
  MGPipeRouteResourceRespecify(desc, nullptr) and drop the Bool, so for a buffer the wait bought a
  value that was thrown away. It goes fire-and-forget with the provisional-accept shape
  resource_subdata has had since item B.
- The texture half keeps its answer ON PURPOSE: there the Bool is the self-heal trigger AND the
  gate on the acceptance mirror, and TextureEmit.h:885-888 (ID-18 M3) says advancing that mirror on
  an unconfirmed answer is how the next identical call gets suppressed "against a record that was
  never stored". That half needs the provisional/really-accepted distinction plumbed through the
  reply mailbox before it can stop waiting; it is not a flag flip.
- MEASURED, same frame, same 101,421,396 B staged: waits 25,176 -> 25,154 and by_op 3=20633 ->
  3=20611. So the buffer half is worth 22 waits (0.1%) and the remaining 20,611 are texture
  respecifies - which is what says the next step is the mirror design, not another flag. Wall
  134.4 s -> 130.9 s.
- The ERROR-is-not-a-decline case moves to the texture half: a row that reads no answer cannot fold
  ERROR into a decision, so the rule it exists for belongs to the half that still waits (the
  transport fault is caught at the next row that does). New case
  ABufferRespecifyTakesNoReplyWhileATextureOneStillDoes pins both directions; red-once with the
  branch removed is exit 155. RemoteClientTest 169/169.
