myomer system COMPLETE -- the 'WAVE 6 mover cutover' was a phantom built on

a misattribution; the authentic couplings are all live

THE CORRECTION [T1]: @004b9550/@004b95b8 ('ConnectToMover'/'Disconnect
FromMover') are MechWeapon::ConfigureMappables/ChooseButton -- their +0x31C
is the weapon TriggerState and **(mech+0x128) is the CONTROLS MAPPER's
button roster (the MECHWEAP.CPP assert string + the trigger-edge detector
@004b9608 sit adjacent in the image).  The binary has NO dynamic myomer->
speed feed: AvailableOutput has exactly TWO callers in the whole image --
RegisterMaxOutput (assembly) and the SeekVoltageGraph sampler -- and
speedEffect@0x31C is a published GAUGE attribute.

The authentic myomer system (now fully live):
1. drive heat (#85, this morning);
2. VITAL death -- myomers are the only authored vital=1 subsystem
   (BTL4.RES res+0x48 scan): destroying them kills the mech via the #80
   vital-crit path (this is also the ram-death mechanism -- myomers are a
   0.35-weight collision-rattle target);
3. the assembly-time gait cap: RegisterMaxOutput @004b8ef0 raises
   mech+0x7A0 to AvailableOutput(top gear) = base x ~1.4284 -- now called
   (idempotent max, per tick; the 0x358 layout lock leaves no latch room)
   with real OwnerBaseSpeed/OwnerMaxSpeed bridges; the old per-frame
   reverseSpeedMax2 heal that would have clobbered it is garbage-guarded;
4. the ENG-page power curve at correct absolute scale (real base speed);
5. electrical sourcing (low gears run on a browned-out generator).

REMOVED (inventions): the mechmppr `speedDemand *= speedEffect` demand
multiplier + BTMyomersDriveOf + the Myomers ConnectToMover/MoverAttach
family.  Damaged-but-alive myomers heat faster and drop the power curve
but do NOT slow the mech (gitea #75's premise is falsified by the binary;
the real damage slowdown is the LEG-damage gimp gait).  Seek gears change
heat/sourcing/graph -- never speed.

Verified live: a mech at myomer dmg=0.234 (speedEffect attr 0.766)
beelines at full commanded speed with dmgGain=1.234 heat; 0 faults.
