DMGTABLE born (type-29 streams, BT411 byte-verified format): the height x angle grid -- DamageLookupTable rows by height, PieSlice cells by angle (rotate-with-torso rows add the live twist), DamageZonePercentTable = the cumulative hit-distribution roll (first threshold above the roll -- the BattleTech dice scatter). Loaded in the Mech ctor by the DamageZoneStream member's NAME (mech+0x444, resident); Mech::TakeDamageMessageHandler resolves invalidDamageZone hits through it (binary @0x4a0264 tail). The missile fuse becomes the authentic unaimed producer: zone -1 + the round's world position as the impact point (ENTITY3.HPP: "damage zones are only valid via reticle based weapons"). Fight-verified on the authentic 7-row bhk1 table: flat-flying SRMs strike low -> row 0 -> FEET AND LEG zones, side-correct by impact angle (+x right, -x left), identical geometry spread across the cell distribution by the roll. 17/17 missile lifecycle, zero faults; smoke + novice green. Also fixed: the ctor's reservedState zero-loop counted past the shrunken array. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
