The relay fires the RunMission pair a fixed 20s after the egg ACK -- but
the ACK happens at egg RECEIPT, and a long mission load (glass + dev
gauges on a busy box measured ~50s) is still in LoadingMission when the
launch lands. L4Application::RunMissionMessageHandler's default case
Fail()ed on that state -- an abort() the 1995 code could afford because
the real console launched operator-paced -- which presented as a SILENT
crash at mission start (c0000409, no WER record; cdb stack:
ucrtbase!abort <- RunMissionMessageHandler <- RoutePacket; 3/3
reproducible; matches the field report's 464 crash that died
mid-LOD-load).
The default case now DEFERS: re-post the message to ourselves at +1s
(the VehicleDead re-post pattern) until the ladder reaches
WaitingForLaunch, bounded at 120 deferrals so a truly wedged load still
surfaces the original Fail. Verified: the crashing console-shaped run
deferred 104x through its ~50s load, then launched, rendered (scene
LIVE) and ran clean.
