Pseudocode for the S2 port (unpack_movement case 0 / move_to_interpreted_state / apply_current_movement / apply_interpreted_movement / DoInterpretedMotion), anchored on decomp lines + validated against a LIVE cdb trace of a retail observer (per-UM DIM order confirmed: style -> forward -> sidestep-stop -> turn-stop; empty UM = wholesale Ready stop). Also settles the packer question: RawMotionState::Pack (0x0051ed10) is pure static-default-difference — outbound L.2b port already verbatim; the empty-vs-explicit walk variance between captures is driver-client state, handled identically by the wholesale apply.

* L.2g S2-blocker trace — what does a RETAIL OBSERVER do with ACE's
|
|
* flags=0 "empty" UpdateMotion while the actor toggles walk/run?
|
|
*
|
|
* Attach target: the retail OBSERVER client (standing still, watching).
|
|
* Driver: the user Shift-toggles + starts/stops the ACTOR from the other
|
|
* retail client.
|
|
*
|
|
* Expected chain per decomp (to confirm or refute):
|
|
* CPhysics::SetObjectMovement (gates, stamps) [SOM] + obj id
|
|
* MovementManager::unpack_movement (10-way dispatch) [UNPACK]
|
|
* CMotionInterp::move_to_interpreted_state (flat copy) [MTIS] + IMS dump
|
|
* CMotionInterp::apply_interpreted_movement [AIM]
|
|
* CMotionInterp::apply_raw_movement (local-player alt) [ARM]
|
|
* CMotionInterp::DoInterpretedMotion per axis [DIM] + motion id
|
|
*
|
|
* The [MTIS] InterpretedMotionState dump on an empty UM is THE answer:
|
|
* if forward_command=0x41000003 (Ready) is flat-applied and [DIM] shows
|
|
* Ready, retail really does stop the remote — and the observer's clean
|
|
* rendering must come from somewhere else. If the dump or the DIM stream
|
|
* shows something else (e.g. WalkForward), we found the mechanism.
|
|
*
|
|
* Auto-detach: after 600 SetObjectMovement hits via .detach (NOT qd —
|
|
* qd is silently ignored in bp actions, see project_retail_debugger.md).
