shims, so the reconstructed integrator @004b8d18 accumulated zero forever
The integrator, its gates and the heat plumbing were all reconstructed and
running -- but OwnerVelocityMag/OwnerDriveMag/OwnerVelocityY/OwnerMotionGain/
OwnerMass were cross-family compile shims returning 0.0f, so the myomers
priced ratio^2 * damageGain * 0 every tick: ice cold at any seek (Oracle's
night-7 panel-confirmed report).
Operands re-grounded against the raw disasm + decomp and mapped to NAMED
members via a complete-Mech-TU bridge (BTMechMyomerMotionSample, mech4.cpp),
per the databinding rule:
+0x1C4 vec -> localVelocity.linearMotion
+0x82C vec -> localAcceleration.linearMotion (the authentic 15-ring
smoothed AccelerationLastFrame the port already maintains)
+0x20C -> moverMass (the collision divert's cell; the old "motion
gain" label was a misread)
*(+0x250) -> environment gravity (FUN_00421e2c: vy -= **(+0x250)/tick),
via GetEnvironment()->gravityConstant
So the heat physics reads: 0.005 * 1/2 m v^2 (kinetic work, per-tick/no-dt
in the binary -- kept verbatim, frame-rate note documented) + 0.2 * m g
|vy| dt (climb power) + 0.2 * m |v||a| dt (acceleration power), all scaled
by ratio^2 and (1 + zone damage). Restored the binary's fabs(v.y) (the
draft had signed vy -- descending would have COOLED).
Authored tuning extracted from BTL4.RES (18 mech records, one shared
tuning): VelocityEfficiency=0.995, AccelerationEfficiency=0.8, gears
0.3/0.5/0.7/0.9999 rec idx 2; myomer thermal profile 77/1000/2000,
conductance 1.9e5, thermalMass 2.5e5.
Live-verified (solo arena, BT_MYO_LOG + BT_HEAT_LOG): standstill generates
~0; hard circling drove Myomers T 77 -> 1225 (past the 1000 degradation
line) and the coolant loop conducted it back to ~520 equilibrium on
slowing; damageGain live at 1.048 from grind rattle.
Known-inert remainder (filed in open-questions): the climb term reads g=0
because Mover::localEnvironment is never populated in the port
(EnvironmentZone res type 23 unwired); the mover feed (speedEffect ->
locomotion) stays WAVE 6.
