WAVE 4 (standalone readouts) -- Sensor(0xBC3)/Searchlight(0xBD8)/ ThermalSight(0xBDE)/AmmoBin(0xBCB) un-stubbed via Create<Class>Subsystem bridges + Torso-style de-shim (drop cross-family shadow fields, redirect accessors to the real inherited base, static_assert layout locks). - FIX: Searchlight/ThermalSight ctors gated their Performance on the shadow segmentFlags(=0) so it NEVER installed; switched to owner->simulationFlags. - AmmoBin: retype ammoAlarm HeatAlarm->WatcherGaugeAlarm(0x54) + drop the statusState@0x40 shadow -> exact 0x22C layout. - Guard HeatWatcher::WatchSimulation against the unresolved watchedLink (null-deref exposed once these sims run; faithful fix = resolve the link). - Heat-leaf branch (Sensor) is not byte-exact -> overflow-lock only. WAVE 6 (Myomers 0xBC6, mover-coupled) -- structural un-stub, gated BT_MYOMERS (default on; =0 -> Actuator stub). Wired INERT: MyomersSimulation early-returns (advanced-damage gate stubbed) + no-op mover feed, so the live JointedMover is untouched and the gait cannot regress. De-shim drops the owner*/segmentFlags shims to fit the exact-0x358 alloc. Authentic mover/heat coupling deferred (needs messmgr 0xBD3 + reconciling the mover feed with the gait cutover). Verified: BLH tick 20->27, Mad Cat 24, combat DESTROYED un-regressed, locomotion un-regressed, 0 crashes, 0 heap detections under BT_HEAPCHECK.

// IMPORTANT CORRECTION (supersedes the earlier powersub.cpp / powersub.hpp

// "Myomers" block):
|
|
//
|

// powersub.cpp/.hpp described a class it CALLED "Myomers" at vtable
|
|
// @0050fb0c / ctor @004b1d18 / classID 0x0BC3, with inferred members
|
|
// outputVoltage/powered/voltageAvailable. That was a MISLABEL. @004b1d18
|
|
// is **Sensor** (proven by the @0050fae0 string pool "Sensor / RadarPercent
|
|
// / SelfTest / BadVoltage" and the surviving SENSOR.HPP); it is now in
|
|
// sensor.cpp with classID 0x0BC3.
|
|
//
|
|
// The REAL Myomers is THIS class:
|
|
// vtable @005117dc (NB: PTR_LAB_005117dc)
|
|
// ctor @004b8fec
|
|
// dtor @004b9114
|
|
// CSS @004b9140 (stamps classID 0x0BC6, streamed model size 0x1B0)
|
|
// DefaultData @0051154c
|
|
// classID 0x0BC6 (Mech factory case 0xBC6, alloc 0x358)
|
|
// The "outputVoltage/powered/voltageAvailable" triad invented in powersub
|
|
// has NO string backing and must be retired. Myomers' real members are
|
|
// the SpeedEffect / SeekVoltage[] drive table below.
|
|
// ===========================================================================

|
// A Myomers IS-A PoweredSubsystem (powersub.hpp): it is driven from a

|

// (drive gears), selectable at run time, and reports the resulting locomotion

// "speed effect" both to the Mech's mover and to the heat model.
