- Advance(dt, Frame? rootMotionFrame) overload: retail's actual root-
motion contract (CSequence::update(quantum, Frame*) 0x00525b80) —
every crossed frame's pos_frame combines into the caller's Frame plus
the sequence velocity/omega via apply_physics. This is the seam R6's
retail per-tick order (CPartArray.Update -> adjust_offset ->
Frame.combine) consumes.
- DELETED: ConsumeRootMotionDelta + the dead adapter accumulator fields
(zero external callers; gap-map API-migration table).
- Root-motion test now asserts REAL accumulation through the wired
Frame path (replaces the P5 inert-stub pin).
- Phase R plan: R1 stage marked SHIPPED with its commit trail.
Full suite green (3346). R1 done: P0 research/pins -> P1 node -> P2
container -> P3 physics -> P4 advance core -> P5 adapter cutover ->
P6 wiring. Next: R2 (GetObjectSequence + MotionTableManager; extraction
workflow already running).
