FREEZE ROOT CAUSE FOUND: a RUNAWAY JSR CYCLE at f=668 pushes ~113 orphaned stack frames IN ONE FRAME (SP $FF→$1C)…

CAPABILITY LANDED: the platform-template STUCK detector now emits [STUCK-STATE] f a x y sp last_addr last_func mem 83 84 8C DC DD E5 E6 EA C8 to stderr before exit(2) — a STUCK verdict now carries its own forensic snapshot (F158 diagnostics pattern; cells chosen for the Asteroids band loop but harmless everywhere). MECHANISM (fits every prior observation): the ship-death path enters, for the first time, a loop whose JSR'd helper hits an F158 deferred…
