Post-respawn under sustained fire the bank fraction hovers at the 0.05 arm
threshold and the plain compare flipped ejectPermitted EVERY FRAME --
hundreds of mode ON/off pairs churning the mask, the lamp, and the arm cue.
The evaluator was dead code in shipped 4.10, so the boundary flap is a
first-ever-exercised condition; completed with the engine's own idiom
(HeatSink coolantActive dual thresholds): ARM below 0.05 (the binary
constant), release above 0.06, no new members. Stress bench: 1 arm
transition in 3 minutes (was: hundreds).
NOTE: the operator's ticking SOUND persists past this fix -- it is the
separate, pre-existing night-10 "audio stutter on coolant leak" family;
hunt continues at the audio-cue chokepoint.
