The local player now drives the SAME pipeline remotes use. The
controller's per-frame RawMotionState rebuild (level-triggered D6.2) is
replaced by retail's CommandInterpreter altitude: key EDGES fire
DoMotion/StopMotion (0x00528d20/0x00528530) and the Shift edge fires
set_hold_run (0x00528b70, caller-0x006b33ca shape) — the interpreter's
own RawState mutates via ApplyMotion/RemoveMotion and every dispatch
routes the funnel + DefaultSink into the sequencer. GameWindow's
UpdatePlayerAnimation (169 lines) is DELETED with both
LocalAnimationCommand/LocalAnimationSpeed MovementResult fields and all
three synthesis sites (K-fix5 pacing, Walk→Run cycle selection, the
auto-walk overrides): run pacing now comes from apply_run_to_command's
my_run_rate promotion — the same source remotes use; airborne-Falling
falls out of contact_allows_move (the funnel's second dispatch).
Auto-walk's #69 turn-phase legs re-expressed as DoMotion(Turn*) edges;
teleport idle = StopCompletely (retail's full stop) + an edge-tracker
reset so held keys walk straight out of a portal.
Map discovery R1 fixed: ChargeJump() now fires at charge START (the
0x0056afac input-boundary site) — StandingLongJump had NEVER armed in
production despite the W3 port.
TWO root-cause fixes the cutover surfaced (each would have been
invisible under the old synthesis layer):
- CurrentHoldKey was a shadow FIELD synced only on the raw dispatch
branch; set_hold_run writes RawState.CurrentHoldKey, so an edge-driven
Shift toggle followed by DoMotion read a stale None and lost the run
promotion. Now an alias of RawState.CurrentHoldKey (retail's
adjust_motion reads raw_state.current_holdkey directly).
- The controller's grounded velocity + jump-launch writes used
set_local_velocity's default autonomous:false, silently clearing
LastMoveWasAutonomous and flipping the A3 dual dispatch to the
interpreted branch for the local player. Both marked autonomous.
EXPECTED-DIFFS (map §6, for the R3 visual pass): #45's 1.248x sidestep
factor + ACDREAM_ANIM_SPEED_SCALE died with UpdatePlayerAnimation —
local sidestep pacing now matches how remotes have always played;
auto-walk-at-run plays walk-pace legs until R4; ApplyServerRunRate's
apply_current_movement goes live (Branch-2 fast re-speed absorbs the
echo — retail's own mid-run speed-change mechanism).
Wire: outbound values stay input-derived (the L.2b-verified byte
stream untouched; RawState-sourcing needs the map §2b cdb TODO and R7
owns outbound). MotionStateChanged = the old comparison minus the dead
localAnimCmd leg, OR any edge fired.
Full suite green: 3,731 passed. Live smoke: in-world, user-driven
input through the new path (walk/turn/strafe), 12k entities, zero
exceptions.

Ports retail's raw->interpreted motion normalization and routes the local
player's velocity through it, so backward/strafe come from the retail source
instead of hand-mirrored controller code (retires register TS-22 + UN-5).
MotionInterpreter (decomp-verbatim, Ghidra/ACE-cross-checked):
- adjust_motion (0x00528010): WalkBackward->WalkForward (x-0.649999976),
TurnLeft->TurnRight (x-1), SideStepLeft->SideStepRight (x-1), sidestep scale
0.5*(WalkAnimSpeed/SidestepAnimSpeed), RunForward early-return, per-channel
holdkey fallback to CurrentHoldKey.
- apply_run_to_command (0x00527be0): WalkForward->RunForward when speed>0 +
UNCONDITIONAL *runRate; TurnRight *1.5; SideStepRight *runRate clamp +/-3.0.
- apply_raw_movement (0x005287e0): copy raw->interpreted, adjust the 3 channels
with per-channel hold keys.
- WalkAnimSpeed unified to the retail-exact 3.11999989f (was 3.12f).
PlayerMovementController: build ONE RawMotionState from MovementInput at
forward_speed=1.0 (apply_run_to_command applies the run rate — a pre-scaled
speed would double-scale), run apply_raw_movement, then take grounded + jump
velocity straight from get_state_velocity (now correct for all directions) and
drive the keyboard turn omega from the interpreted turn_speed (BaseTurnRate x
turn_speed = the same pi/2 formula the remote path uses; numerically identical
to the old TurnRateFor). Deleted the hand-mirrored backward(x-0.65) /
strafe(x+-1.25) formulas in both the grounded and jump blocks. Mouse turn and
the auto-walk path are untouched.
Retail-faithful behavior changes (confirm in smoke): strafe is now
1.25 * ~1.248 * runRate = ~1.56*runRate, clamped via SideStepSpeed<=3.0 so
|v.X|<=3.75 (was 1.25*runRate, no scale/clamp); backward is unchanged
(3.12*0.65*runRate); backward/strafe-left velocity now comes from the pipeline
instead of returning zero. Forward run pace unchanged (4.0*runRate).
Tests: MotionNormalizationTests (17, adjust_motion/apply_run_to_command) +
MotionVelocityPipelineTests (10, apply_raw_movement->get_state_velocity golden
velocities incl. the strafe clamp + turn speeds). Full suite green (3255).
Register: TS-22 + UN-5 deleted (retired); TS-34 added (adjust_motion creature
guard is a no-op — IWeenieObject has no IsCreature; correct for the only caller,
the player). Pseudocode: docs/research/2026-07-01-d6-motion-interp-pseudocode.md.
NEXT D6.2b: the echo-gated wire forward_speed=1.0 question (evidence suggests
ACE relays rather than recomputes; verified via the smoke echo).
