User report: enemy takes hits, starts smoking, then beams pass through
-- no more damage, no death. Root cause: the death-effects dispatch
(blhdead explosion chain + wreck swap + KILL score) lived in the
SHOOTER's laser fire block kill check. A missile killing blow lands
frames later in BTUpdateProjectiles -- outside that block -- and after
task #41 the boresight pick skips a dead mech, so the fire block never
ran against it again: the death chain was silently skipped, leaving an
internally-dead, smoking, standing, invulnerable mech.
Fix: the dispatch moved to the VICTIM's own once-per-death transition
(UpdateDeathState's movementMode->9 moment) -- fires exactly once for
ANY kill source (laser, missile, collision). Killer id for the
Explosion message = lastInflictingID (the task-#31 bookkeeping). The
BT_ENABLE_TEARDOWN cdb harness was removed with the old block (findings
preserved in docs/HARD_PROBLEMS.md).
Verified headless (75s soak, missile-heavy kill): destroyed ->
'blhdead' id=22 -> wreck swap 'blhdbr.bgf' -> smoke re-arm -> sink ->
buried INERT; post-death picks fall through to terrain; 0 crashes.
