The BT keyframe-animation player embedded in the Mech as legAnimation/ bodyAnimation. Struct field layout (from BT411's binary-offset map), default ctor, dtor, and Init(Mech*) reconstructed and compile-verified; Init is ctor-time (Mech ctor calls legAnimation.Init(this)/bodyAnimation.Init(this)) so it's real (binds owner + caches owner->GetJointSubsystem()). The per-frame gait engine (SelectSequence/Advance/Reset) is staged with Fail bodies -- it fires only once the mech is ticking, past the current ctor frontier. BT stage 23 ok; full tree still links clean. Evidence + real/staged split in SEQCTL.NOTES.md. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

// The BT keyframe-animation player embedded in the Mech as legAnimation and

|
|
// subsystem, and returns the root-translation distance advanced this step.
