Three root causes, all fixed: 1. kDamageScale was 1.0 -- _DAT_004bafbc is an x87 float80 = 1e-7, cancelling the ctor's x1e7: damagePortion = authored DamageAmount x (charge/seekV)^2 (closed form at fire time; madcat AC=25/LRM=50/ERLL=6, bhk1 PPC=12/SRM=35). The observed "0.25" was the degenerate EC=1 fallback, never authored data. 2. CheckFireEdge NaN latch: TriggerState carries ControlsButton INTS; the release value (-65) is a negative NaN. The binary's x87 unordered compare read it as "released"; IEEE-correct float compares latched the edge detector shut after the first release -- the reason the emitter discharge chain NEVER fired in-game. Fixed with bit-pattern sign compares. 3. The weapon-side submission LIVE: Emitter::FireWeapon fills damageData (amount + damageForce=target-muzzle [the gyro directional-bounce feed] + impact) -> MechWeapon::SendDamageMessage (@004b9728 real body) -> messmgr consolidation with per-weapon records + explosion bundling. The mech4 bring-up damage block + flat kShotDamage retired to diag hooks. Bonus: LODReuseHysteresis 0.82 -> 0.33 (double misread). Zone model verified byte-exact (no change). Solo end-to-end: 5-record volleys (2 PPC + 3 ERML with authored amounts), per-weapon zone granularity, explosions, kill. Heat stays bring-up scale pending the heat-calibration audit [T3].
