The death-row page fault was the THIRD strike of the uninitialized
zone-array trap: the staged spawn rides the mech family's resourceID, whose
DamageZoneStream makes the Entity base ctor allocate the 20-pointer
damageZones[] array with UNINITIALIZED slots -- the Missile never fills it,
and ~Entity's teardown deleted 20 garbage pointers through trash vtables
(the dtor-chain bisect showed every dtor completing, then EIP-in-heap).
Fix: the Projectile ctor NULLs every inherited zone slot. RULE, now
three-crashes-proven: any entity subclass that does not FILL the allocated
zone array must NULL it -- the engine never initializes the slots, on
construction OR destruction.
Missiles are now the default SRM delivery (BT_MISSILE_INSTANT=1 = the
5.3.18a instant-hit as an A/B opt-out). Verified: 20 launches -> 20
detonations -> 20 clean death-row teardowns over a 110s mutual fight, zero
faults; smoke + novice regressions green.
