AnimationSequencer.Advance() allocated a fresh PartTransform[partCount]
every call (BuildBlendedFrame/BuildIdentityFrame), and GameWindow.
TickAnimations reassigned entity.MeshRefs to a fresh List<MeshRef>(partCount)
every tick for every animated entity - including idle NPCs on a breathe
cycle. Both fire every frame in steady state and both become garbage
immediately after being consumed.
Fix: cache a PartTransform[] sized once in the AnimationSequencer
constructor (_setup is readonly and never reassigned, so partCount is
fixed for the sequencer's lifetime) and overwrite it in place each
Advance() call. Cache a List<MeshRef> on the long-lived AnimatedEntity
record (one per animated entity, held in GameWindow._animatedEntities)
and Clear()+refill it each tick instead of allocating a new list.
Verified safe: TickAnimations runs single-threaded to completion before
any draw-side consumer reads MeshRefs (WbDrawDispatcher re-reads
entity.MeshRefs fresh every frame, keyed by entity.Id - it never caches
the list reference across frames). The only place that copies MeshRefs
across an animation boundary (RefreshPaperdollDoll) takes an explicit
`new List<MeshRef>(pe.MeshRefs)` value copy; MeshRef is a readonly
record struct so that copy is unaffected by later in-place mutation of
the source list. No test holds two Advance() results simultaneously.

The P2 cellar-lip lesson one loop deeper. CheckOtherCells takes footCenter
by value and used it for every cell in the loop — but a mid-loop query can
MOVE the sphere: at the Facility Hub cell boundaries the neighbor's ramp
floor full-hits, step_sphere_up climbs the foot +0.6mm and returns OK, and
the loop continued querying the REMAINING cells (including the under-room,
portal-ring-3) at the pre-climb height — 0.4mm inside the double-faced
floor slab, grazing its underside (the under-room's ceiling) within the
near-miss window. That dispatched a neg-poly step-up with a DOWNWARD
normal, whose failure funneled into slide_sphere's opposing branch ->
synthetic reversed-movement collision -> Collided -> revert, every frame:
the seam shake (and, pre-mechanism-2-fix, the original absorbing wedge's
entry).
Retail check_other_cells reads the LIVE sphere_path.global_sphere for
every cell (each cell's find_collisions receives the transition itself,
pc:272717+). Fix: re-read footCenter = sp.GlobalSphere[0].Origin at the
top of each loop iteration.

The mechanism-1 theory (PortalSide portal polys solid in our physics set)
is REFUTED for the corridor repro, and the remaining half of the phantom
is fixed — no cdb session needed:
- The live hit normal (-1.00,0.03,-0.03) matches NO dat polygon: a
world-space sweep of both seam cells + every portal-adjacent neighbor
(CorridorSeam_FindPolygonMatchingLiveHit) returns zero candidates. The
normal is the negated movement direction — the SYNTHETIC value
slide_sphere's opposing-normals branch records (reversed = -gDelta).
- Cell 0x8A02016E has IDENTITY rotation (the prior session's 'rotation
maps the portal planes into the -X wall' was a misattribution). The
PortalSide polys to 0x011E are +-Y planes 1.4 m beside the player's
track, perpendicular to the +X run — pos_hits_sphere's directional
cull rejects them for that movement. They ARE referenced by the dat's
physics-BSP leaves (CorridorCell_PhysicsBspLeafMembership), so retail
tests them too when approached into their plane; the dat's
keep-PortalSide / strip-ExactMatch asymmetry reads as intentional
(solid window/grate-class portals). No portal-poly filter — exactly
the blanket-skip the pickup warned against.
- Port fix: CSphere::slide_sphere's opposing-normals branch
(0x005375d7-0x0053762c) records the reversed displacement and returns
COLLIDED_TS; our port returned OK ('retail returns OK here' was a
decomp misread), letting the step complete as-is with the synthetic
collision normal that validate's epilogue then persisted as the
sliding normal the wedge absorbed on. TransitionTypes opposing branch
now returns Collided; pinned by
SlideSphere_OpposingNormals_ReturnsCollided_WithReversedDisplacementNormal
(RED->GREEN).
- Dat-backed replay (Issue137CorridorSeamReplayTests) reproduces the
live hit frame verbatim (same in/out to the millimeter, same 016E->017A
transit, same +8mm settle) and runs the corridor CLEAN: hit=no, no
sliding normal persisted, six further forward frames advance freely.
- Inspection tests extended: physics-BSP leaf membership walk +
hit-normal candidate sweep + downward-poly sweep (all report-style,
dat-gated). Pickup prompt banner'd SUPERSEDED; ISSUES #137 updated
(door half stays open); audit doc extended with the resolution.

The Facility Hub corridor dead-stop's second half: after one seam hit,
every forward resolve returned ok=False hit=no with zero advance. The
body-persisted SlidingNormal (-1,0,0) projected the exactly-anti-parallel
corridor push to zero in AdjustOffset and the step loop aborted at step 0
before any collision test could refresh the state.
Audit (docs/research/2026-07-06-137-sliding-normal-lifecycle-audit.md):
retail's only in-transition sliding-normal writer is validate_transition
(0x0050ac21); the whole sphere/BSP layer writes NONE (grep-verified), and
the body persistence (SetPositionInternal 0x005154c2, SLIDING_TS bit sync
0x005154e1) runs only on transition success. Our BSPQuery Contact-branch
full-hit responses were stubs (SetCollisionNormal + SetSlidingNormal +
return Slid) where retail dispatches the real slide_sphere — so the seam
hit (a SUCCESSFUL full-advance resolve per the live log) persisted the
phantom wall's normal, which retail's lifecycle structurally cannot do.
- BSPQuery Contact foot full-hit fallback + head full-hit now route
through Transition.SlideSphereInternal (CSphere::slide_sphere
0x00537440 — in-frame slide, no sliding-normal write; ACE
BSPTree.cs:202,310-316). The dead stub is rewritten as the faithful
BSPTREE::slide_sphere wrapper.
- PhysicsEngine sliding writeback gated on ok (retail success-only
placement; behaviorally latent, removes the failed-frame leak class).
- Register: TS-4 amended (Path-6 steep-tangent sites still write the
normal — now documented), TS-45 added (SphereCollision's write — same
leak class, left for a follow-up out of #171's blast radius).
- Pins: Issue137SlidingNormalLifecycleTests — both site pins RED->GREEN,
plus the retail persist/absorb/clear wall lifecycle (validate-write
persistence, faithful absorbed anti-parallel frame, oblique escape
clears the bit). BSPQueryTests full-hit pin updated to the real slide.
Mechanism 1 (PortalSide portal polys solid in the physics set) stays
OPEN - #137 not closed; the corridor re-test rides that session.

The shipped derivation looked up mt.Cycles[DefaultStyle]; the dat
Cycles dictionary is keyed by the COMBINED (style << 16) | substate
word (CMotionTable.cs:683), so the lookup always missed and the pose
override silently fell back to placement frames — user re-test: "175
is not fixed". The pins covered the override plumbing but not the
derivation, the one part with no offline fixture.
Extract the derivation to Core as MotionTablePose.DefaultStatePartFrames
using the retail SetDefaultState chain (StyleDefaults[DefaultStyle] ->
combined-key LookupCycle, same wrap arithmetic as CMotionTable.cs:683)
and pin it against the REAL dat (human MT 0x09000001 resolves a
34-part pose — this test fails on the old key math). Short poses now
apply PER PART (ShadowShapeBuilder already falls back per index) so a
door anim posing only the panels still overrides them while the
BSP-less header keeps its placement frame. [shape-pose] diagnostic
(ACDREAM_DUMP_MOTION) prints mt id + resolved part0 pose per BSP
registration so live launches show the actual outcome.

The Facility Hub double door (Setup 0x02000C9D) embeds the player into
the visual panel from one side and blocks with a phantom slab on the
other: its Setup PLACEMENT frames pose the two panels AJAR (yaw
-150/-30 deg, 0.44 m behind the doorway plane — dat-confirmed by the
Issue175 inspection) while the rendered door poses them CLOSED from
the wire-supplied motion table via the sequencer. ShadowShapeBuilder
read placement frames, so the 1.66x0.29x2.95 m physics slabs
registered at the ajar pose. Retail tests each part's LIVE
CPhysicsPart pose — for an idle door, the motion table's default
(closed) state.
Fix: ShadowShapeBuilder.FromSetup gains partPoseOverride (BSP part
shapes only); RegisterServerEntityCollision derives it from the spawn
MotionTableId via GameWindow.MotionTableDefaultPose (default style ->
first cycle -> LowFrame part frames). Null/short poses fall back
per-part to placement frames — table-less entities and landblock
statics unchanged. One-shot snapshot vs retail's per-frame live pose
is register row AP-84 (equivalent for the door lifecycle: closed ==
default pose; open == ETHEREAL bypasses collision, #150).

The Holtburg town-network portal platform (stab 0xC0A9B465, Setup
0x020019E3, CylSphere r=2.597m h=0.256m) blocked the player with an
endless rim slide instead of retail's step-up-onto-top — gating the
whole #137 dungeon repro. Surfaced when #149 started registering
BSP-less stab CylSpheres: the collision SHAPE became right while the
RESPONSE was still the hand-rolled AP-6 approximation (step-up gate +
radial wall-slide only).
Root cause: no cylinder-TOP support anywhere. DoStepUp's internal
step-down probe needs retail's step_sphere_down (0x0053a9b0) to land on
the flat top — a cylinder has no polygons for the walkable search — so
every step-up onto a wide cylinder failed into StepUpSlide and the
player orbited the rim (probe-confirmed: [cyl-test] result=Slid with
horizontal rim normals, launch-137-repro.log).

Structural capstone of the R5 movement-manager arc; zero behavior change.
Retail MovementManager (acclient.h /* 3463 */, 16 bytes / four pointers)
gives every CPhysicsObj ONE owner for its motion_interpreter +
moveto_manager. acdream carried them as loose per-entity objects wired by
hand at three sites. This slice:
- New src/AcDream.Core/Physics/Motion/MovementManager.cs — owns
MotionInterpreter + lazy MoveToManager (MakeMoveToManager 0x00524000 via
a MoveToFactory closure, the acdream stand-in for the physics_obj/
weenie_obj backpointers) + the relays with retail call shapes:
PerformMovement 0x005240d0 (types 1-5 -> minterp, 6-9 ->
MakeMoveToManager + moveto, (type-1)>8 -> 0x47), UseTime 0x005242f0
(moveto only), HitGround 0x00524300 (minterp FIRST then moveto),
HandleExitWorld 0x00524350 (minterp only), CancelMoveTo 0x005241b0,
HandleUpdateTarget 0x00524790, IsMovingTo 0x00524260.
- RemoteMotion.Movement + PlayerMovementController.Movement hold the ONE
facade; Motion/MoveTo become child views so the comment-dense call sites
read unchanged. The three wiring sites (EnsureRemoteMotionBindings,
EnterPlayerModeNow, the chase harness — same commit per the mirror rule)
construct through MoveToFactory + MakeMoveToManager(), preserving the
pre-facade eager timing (side-effect-free ctor = unobservable either way).
- Relay call sites repointed: both remote landing HitGround pairs + the
player landing pair, despawn HandleExitWorld, TickRemoteMoveTo + the
player Update UseTime, RouteServerMoveTo (takes the facade; routes via
the retail PerformMovement dispatch), InstallSpeculativeTurnToTarget,
host HandleUpdateTarget/InterruptCurrentMovement closures (retail
CPhysicsObj::HandleUpdateTarget @0x00512bf0 fan head + the TS-36
interrupt chain, now the literal facade relays).
- NOT absorbed per the slice spec: unpack_movement stays App
(RouteServerMoveTo + UM heads; Core.Net types stay out of Core.Physics);
TS-42 per-tick order untouched (R6); #170/#171 gate-passed machinery
untouched. PerformMovement's set_active(1) head not re-asserted (spawn
asserts Active; status quo — no new register row).
- Register: TS-41/TS-42 source wording freshened to the facade shape;
AD-36 retire note corrected (facade half closed; residue = entities
that never get a RemoteMotion). No new rows.
- Conformance: 15 new MovementManagerTests pin the dispatch table, lazy
create, relay targets/order, null tolerance. Suite 4052 green; the
183-case/funnel/moveto/chase/sticky suites UNMODIFIED (harness
construction mirrors production, test bodies untouched).

Three unpack_movement parity items (facade deferred per the handoff's
own optional clause — see r5-wiring-handoff §V4 status):
1. HEAD style-on-change (0x00524440 @00524502-0052452c): both GameWindow
routing heads (remote + player) now dispatch DoMotion(style, ctor
defaults) when the UM's stance differs from the interp's current
style, BEFORE the movement-type routing — for EVERY type. Previously
style applied only through the mt-0 funnel copy, so a chase/turn UM
(mt 6-9) carrying a stance change started the move in the OLD stance
(a monster charged in NonCombat posture until the next mt-0). The
RetailObserverTraceConformanceTests exclusion note updated — the
trace filter stays (head calls can't appear in a
MoveToInterpretedState replay) but the production gap it pointed at
is closed.
2. #164 (closes): the action-replay loop threads each action's autonomy
into the dispatch params (Autonomous = the 0x1000 splice, raw
305982) — replayed actions enter the interpreted actions list with
their real autonomy instead of ctor-default false.
3. mt-0 wire flags consumed (UpdateMotion parsed them since R4-V3):
0x1 StickToObject → CPhysicsObj::stick_to_object port (0x005127e0:
resolve target, PartArray radii — 0 when shapeless, guid-as-is for
acdream's flat entity table — → PositionManager.StickTo; unresolvable
target → no stick), at BOTH case-0 tails in retail order
(@00524583-0052458e: funnel apply → stick → longjump flag);
0x2 StandingLongJump → Motion.StandingLongJump, UNCONDITIONAL write
(absent flag clears — retail @0052458e). ServerMotionState gains the
StandingLongJump field.

Gate 2: pack behavior good except "sometimes the monster is in the
character / too close vs retail". The ACDREAM_PROBE_STICKY capture
nailed it frame-by-frame: 1661 deep-overlap AdjustOffset ticks, ALL
steering inward (dist -0.65 -> -0.78 -> ... -> -1.9 at +0.13/tick),
monsters converging to centerDist~0 — while the suppressed-snap lines
show ACE's authoritative positions stayed properly OUTSIDE (drift up to
7.7 m). The radii were correct (tgtR=0.68, ownR=0.59-0.98).
Root cause: ACE's literal decode of StickyManager::adjust_offset
(`if (delta >= |dist|) delta = dist;`) leaves delta POSITIVE when the
overlap exceeds one tick's step — steering TOWARD the target center, a
runaway whose equilibrium is centers-coincident. ACE servers virtually
never reach that branch (quantum >=1/30 -> threshold ~1 m); at
render-rate quanta the threshold is ~0.13 m and pack jostle trips it
constantly. The BN mush (0x00555554-0x00555597) is unreadable on
exactly this compare; the retail oracle (side-by-side on the same ACE:
monsters separate) refutes the ACE-literal reading.
Pin: sign-correct clamp — `else if (dist < 0) delta = -delta` (back off
rate-limited). Identical to ACE-literal in every shallow/outside case.
Register row AP-82 (same commit) with the cdb verification note.

Gate 1 (2026-07-04): "better in general" + three residuals — monsters
pushed INTO the player, attacks with stale facing, position
"flashing/flapping instead of gliding". All three are ONE mechanism:
the legacy NPC UpdatePosition handler hard-snaps position, orientation,
and velocity/cycle UNCONDITIONALLY, fighting the armed sticky every UP
(ACE's authoritative rest pose sits ~0.6 m out and its server-side
facing lags the strafing target; the client stick holds 0.3 m + live
facing — oscillation at UP cadence).
Retail is immune by architecture, not by tuning: UP corrections flow
through the InterpolationManager into the SAME per-tick
PositionManager::adjust_offset chain where StickyManager::adjust_offset
OVERWRITES them while armed (0x00555190 chain order; 0x00555430 assigns
m_fOrigin). A server correction can never fight an armed stick
frame-by-frame. The remote-player branch already has exactly that
(queue -> combiner -> sticky overwrite); the legacy NPC path snaps
outside the chain.
Fix: suppress the NPC UP position/orientation/velocity-adoption snaps
while the entity is stuck (PositionManager.GetStickyObjectId() != 0) —
the retail chain semantics translated to the snap architecture.
LastServerPos/Time + cell bookkeeping still record; server truth
reasserts on the first UP after unstick, bounded by the 1 s sticky
lease. Register row TS-44 (same commit); retires with the S6/R6
interp-queue unification of the NPC path.
Apparatus: ACDREAM_PROBE_STICKY=1 — per-guid [sticky] lifecycle lines
(STICK / UNSTICK / LEASE-EXPIRE / TARGET-status teardown), per-armed-
tick steer lines (signed gap dist, applied delta, heading delta, live
resolve), and [sticky-snap-skip] at the suppressed-snap site.
PhysicsDiagnostics.ProbeStickyEnabled owns the flag (rule #5).
Full suite 4038 green. Awaiting gate 2 (pack melee vs retail).

Group-melee interpenetration + facing drift: the R5-V1-ported
StickyManager/PositionManager were Core-only — the StickTo/Unstick seams
were unbound and every arrival radius was 0, so ACE's Sticky|UseSpheres
melee chases closed ~one body-radius too deep and froze at stale arrival
poses until the next wire re-arm. Retires TS-39.
Wiring (anchors re-verified against the named decomp this session):
- EntityPhysicsHost owns a PositionManager; HandleUpdateTarget fans
MoveToManager then PositionManager (CPhysicsObj::HandleUpdateTarget
0x00512bc0 order).
- Seams bound remote + player: MoveToManager.StickTo (BeginNextNode
sticky arrival @0x00529d3a), Unstick (PerformMovement head), and
MotionInterpreter.UnstickFromObject (UM funnel head, 0x0050eaea).
- AdjustOffset at the retail UpdatePositionInternal slot (@0x00512d0e):
NPC branch composes pre-sweep (steer is swept by ResolveWithTransition);
remote-player branch chains the combiner offset through the shared
delta frame (the interp stage) so sticky OVERWRITES when armed
(0x00555430 assigns m_fOrigin, not accumulates); player inside the
30 Hz physics quantum before UpdatePhysicsInternal.
- UseTime (the 1 s lease watchdog) at the UpdateObjectInternal tail
(@0x005159b3): unconditional per remote; player gated on the physics
tick (retail's MinQuantum gate skips UseTime too).
- Real setup cylsphere radii (CPartArray::GetRadius/GetHeight
0x005180a0/0x005180b0 = setup radius/height x ObjScale from the spawn
record): own via EnsureRemoteMotionBindings + player wiring; target via
RouteServerMoveTo AND the speculative use-walk install (retail resolves
the target PartArray at EVERY MoveToObject site — ACE PhysicsObj.cs:951).
- Teardown parity: exit_world (0x00514e60) UnStick + ClearTarget before
the ExitWorld notify; player teleport fires teleport_hook's tail
(UnStick in SetPosition + EntityPhysicsHost.NotifyTeleported =
ClearTarget + NotifyVoyeurOfEvent(Teleported) @0x00514f1b) so mobs
stuck to the player drop their sticks on a recall.
- SERVERVEL arbitration also yields to a stuck entity (same starvation
class as the #170 fix — sticky owns the between-snap translation).
- StickyManager.UseTime aligned to retail's strict > deadline
(0x00555626; ACE >): two V1 tests had pinned the >= edge — corrected.
Register: TS-39 deleted; TS-41 narrowed (stickyArmed gate); TS-43 added
(remote teleport_hook gap — self-corrects within the 1 s lease); AP-23
narrowed (real radii at the speculative site; only the use-radius
buckets remain invented).
Conformance: 2 new full-stack sticky scenarios in
RemoteChaseEndToEndHarnessTests (arrive -> stick -> strafing-target
gap+facing track -> lease expiry; unstick-on-rearm -> re-stick).
Full suite 4038 green.
Pre-commit adversarial diff review (3 lenses + per-finding refuters)
confirmed and fixed 4 findings: ObjScale-dead radius read, player
UseTime order inversion, missing teleport voyeur notify, speculative-
site radius asymmetry.
Awaiting the user visual gate: pack melee side-by-side vs retail
(attackers reshuffle + keep facing; some overlap is ACE-server-side).

Gate result: user side-by-side vs retail — "looks good, as close to retail
now as I can see". Telemetry from the gate session (launch-170-gate2.log):
BeginMoveForward ~1:1 with MoveToObject arms for every chasing creature
(pre-fix capture was 16:1), ZERO "SERVERVEL skips UseTime while armed"
occurrences, pending_motions depth 1 at last sample.
Stripped per the #170 close-out plan: s_mvtoDiag + all [mvto] prints

(GameWindow). The durable ACDREAM_DUMP_MOTION family stays. The

suites stay as the permanent regression net for this pipeline.

Live retail cdb tracing + acdream probes root-caused the creature chase "slide"
end-to-end, SUPERSEDING the earlier MovementManager-coexistence hypothesis
(eb423fb7):
Chase run cycle is manufactured client-side from mt-6 MoveToObject:
HandleUpdateTarget -> MoveToObject_Internal -> (TurnToHeading node completes
via UseTime) -> BeginMoveForward -> _DoMotion(RunForward) sets substate.
BeginTurnToHeading (MoveToManager 0x00529b90) bails while
CMotionInterp.motions_pending is non-empty (retail-faithful).
acdream's pending_motions EXPLODED to ~1.3M entries (live: add=1.37M vs
done=5.7K) because the NPC per-tick called rm.Motion.apply_current_movement
EVERY FRAME, which for a remote (has a DefaultSink) re-ran
ApplyInterpretedMovement and re-dispatched the WHOLE interpreted state (stance
0x8000003C + forward=attack + sidestep/turn stops), each appending a
pending_motions node that barely drains. => MotionsPending() permanently true
=> the chase turn never started => BeginMoveForward/RunForward ~never fired =>
the creature slid in an idle+attack pose. Retail dispatches per MOTION EVENT
(per UM), never per frame — cdb drain trace: retail add_to_queue == MotionDone.
FIX: delete the per-frame apply_current_movement call in the grounded remote-NPC
dead-reckon path (GameWindow ~9992). The motion is already dispatched per UM by
the funnel (MoveToInterpretedState) + by the MoveToManager per node; body
velocity is refreshed directly by the existing get_state_velocity line.
RESULT (verified live): pending_motions depth 1.3M -> ~1 (add~=done); "stuck in
attack animation" GONE (user-confirmed); run cycle now installs (BeginMoveForward
1->10, RunForward held 0->7). PARTIAL: still not fully sustained — BeginTurnToHeading
still blocked motionsPending=True 256/272 (94%) because a residual Ready
(0x41000003) stop-node backlog keeps the queue from fully emptying between swings
(retail hits add==done exactly). acdream gets ~10 run-starts vs retail's ~21, so
it now twitches+glides instead of a clean run-then-stop. Residual = the R2/R3
Ready-stop drain (next session; see docs/research/2026-07-04-*-handoff.md).
Also includes the env-gated #170 diagnostic probes used to find this
(ACDREAM_MVTO_DIAG=1: [mvto]/[npc-tick]/[drain]/[drainq]) — TEMPORARY, strip when
#170 closes. No effect on normal runs. Core suite green.

bounded turn-to-face; 1 s watchdog; Ok→initialized / non-Ok→teardown.
- ConstraintManager (0x00556090): the server-position rubber-band leash.
90% IsFullyConstrained jump gate + grounded linear brake taper.
Structural only — acdream never ARMS it (retail arms from
SmartBox::HandleReceivedPosition, which acdream lacks, with two x87
constants BN elided). IsFullyConstrained stays false = TS-35 behavior;
leash-arming + the unknown constants are a deferred issue.
- PositionManager facade (0x00555160): lazy Sticky/Constraint + fan-out.
- TargetManager (0x0051a370) + TargettedVoyeurInfo: the peer-to-peer
voyeur subscription system (0.5 s throttle, 10 s staleness,
send-on-drift-past-radius, dead-reckon GetInterpolatedPosition). A
faithful superset of the AP-79 adapter — SetTarget subscribes ON the
target; the target's HandleTargetting pushes updates back.
- IPhysicsObjHost: the CPhysicsObj back-pointer seam (position/velocity/
radius/contact/GetObjectA + target-tracking fan-out) the App wires per
entity in V2/V3. MotionDeltaFrame: mutable retail-Frame delta accumulator.
Supporting:
- TargetInfo extended to the full retail 10-field struct (additive
defaults keep the R4 4-arg call sites compiling).
- MoveToMath: signed CylinderDistanceNoZ, NormalizeCheckSmall,
GlobalToLocalVec.
- Rename: the misnamed AcDream.Core.Physics.PositionManager (a remote
anim+interp per-frame combiner, NOT the retail facade) → RemoteMotion
Combiner, freeing the name and removing the ambiguity that breaks every
file importing both Physics + Physics.Motion (GameWindow will in V2/V3).
Tests: 42 new conformance cases (Sticky/Constraint/Position facade +
TargetManager incl. the full cross-entity voyeur round-trip). Full suite
4006 green (+2 skipped), no regressions.
Decomp + ACE cross-ref + port plan: docs/research/2026-07-03-r5-managers/.

Retail's apply_interpreted_movement (0x00528600) does NOT dispatch with
ctor-default MovementParameters: the BN decomp smears the bitfield store
into the mush expression at raw 305778 - (word & 0x37ff) | cancelMoveTo<<15
| disableJump<<17 - which CLEARS SetHoldKey/ModifyInterpretedState/
CancelMoveTo. ACE MotionInterp.cs:444-449 confirms independently. Three
legs fixed, all retail decode, no adaptations added:
1. ApplyInterpretedMovement now builds the pass params retail actually
uses (ModifyInterpretedState=false is load-bearing): no dispatch in the
pass writes InterpretedState, so the airborne Falling substitution
PRESERVES the wire's forward command and HitGround's re-apply
dispatches it - the motion table plays the Falling->X landing link.
The W6 entry-cache (built on the wrong "retail self-heals via hoisted
registers" theory) is deleted; live reads are retail semantics. Raw
arg3 decoded as DisableJumpDuringLink -> every (N,0) caller means
allowJump=true; all 9 caller polarities fixed. copy_movement_from's
current_style copy (raw 0051e757) added to the UM flat-copy.
2. Both GameWindow landing blocks cleared the Gravity state bit BEFORE
Motion.HitGround(), whose verbatim state&0x400 gate then no-opped the
whole retail re-apply; the UP-driven landing block never called
HitGround at all. Both now run HitGround (minterp then moveto,
MovementManager::HitGround 0x00524300 order) with Gravity still set,
then do the DR bookkeeping clear (register row AP-81 added for the
remaining flag dance, retire in R6).
3. K-fix17's forced SetCycle (both copies) deleted: it executed every
landing but read the leg-1-clobbered ForwardCommand (0x40000015) and
re-set the very Falling cycle it meant to clear.
Tests: new HitGround_AfterFall_RedispatchesPreservedForward_ExitsFalling
lifecycle pin; AirborneBody state assertion flipped (it had pinned the
bug value). Suite 3,964 green incl. the 183-case retail-observer trace.
Filed #164 (action-replay Autonomous bit, no current consumer).
Awaiting live verify: stand-still landing must exit the falling pose with
zero wire input.

User observation (acdream observing a retail player's server MoveTo):
walk-distance approaches correct; run-distance plays the run cycle AND
moves toward the target in slow motion.
Root cause, raw-verified (apply_run_to_command 0x00527be0, raw
305062-305076): retail's rate chain is
weenie ? (InqRunRate() ?: my_run_rate) : 1.0
Every placed retail object HAS a weenie; a REMOTE's weenie fails
InqRunRate (no local skill data) and the chain lands on my_run_rate -
the exact field retail's mt-6/7 unpack writes with the wire's
MoveToRunRate (M13; observed 4.50). Our port had the branch verbatim
but remote interps carried NO weenie at all, taking the else-1.0
branch retail reserves for weenie-less detached objects: observer-side
run dispatches went out at speed 1.0, so the run cycle's pace AND
get_state_velocity's chase speed both crawled. Walk was unaffected -
walk speed is never rate-scaled (the discriminating symptom).
Fix: RemoteWeenie (Core) - the minimal stand-in for retail's
per-object ACCWeenieObject: InqRunRate fails (-> my_run_rate),
InqJumpVelocity fails, IsThePlayer default false (also ends the
fragile "null weenie counts as the player" reading of the A3 dual
dispatch for remotes), IsCreature default true (doors carry it too;
their force-asserted Contact keeps the creature ground-gate moot -
documented on the class). RemoteMotion's interp now constructs with
it.
Tests: RemoteWeenieRunRateTests pins both branches against the raw -
RemoteWeenie + MyRunRate=4.5 promotes WalkForward->RunForward @ 4.5;
weenie-less keeps the verbatim degenerate 1.0. Full suite green: 3,963.

Root cause (pinned by the worktree investigation + verified against
source): CMotionInterp's dispatch tails strip link animations for
DETACHED objects only (retail `if (physics_obj->cell == 0)
RemoveLinkAnimations`, raw @305627, three ported sites:
DoInterpretedMotion / StopInterpretedMotion / StopCompletely). The R3
port proxied retail's cell pointer with CellPosition.ObjCellId == 0 -
but that #145 field is seeded ONLY by SnapToCell, whose single
production caller is the LOCAL PLAYER's SetPosition. Every REMOTE body
therefore read "detached" forever, and every dispatch stripped the
transition link the motion table had just appended: a used door's
swing link died the same tick (pose snapped closed<->open - the live
symptom), and remote walk<->run link poses have been silently eaten
since the guard landed (masked: locomotion cycles resemble each other;
a door's two poses don't). The dispatcher itself (GetObjectSequence
link path) was verified retail-verbatim end-to-end - not the bug.
Fix: PhysicsBody.InWorld - an explicit "placed in the world" flag
carrying exactly the guard's retail meaning (register row TS-40,
replacing the previously UNREGISTERED ObjCellId proxy). Set by
SnapToCell (retail: enter_world/set_cell assigns the cell) and by
RemoteMotion construction (a RemoteMotion exists only for a world
entity). All three guard sites now test !InWorld. Default false =
retail's pre-enter_world detached state, preserving the guard for
genuinely unplaced bodies (bare-harness interps unchanged).
Tests: InWorldLinkGuardTests pins the polarity at all guard classes
(in-world dispatch keeps links; detached strips; StopCompletely same).
Full suite green: 3,961.
If the door still snaps after this, the open question is DATA (does
the door's table author an On<->Off link at all) - next step per the
investigation: dump the real table's Links/StyleDefaults via a
DoorSetupGfxObjInspectionTests extension.

Live bug (2026-07-03, user door test): a server MoveTo armed
(movingTo=True) but the local body never moved; the retail observer saw
ACE walk the server-side player to the door; the next local input
reasserted the stale position (rubber-band). Log evidence: the player's
pending_motions queue was non-empty on 92/94 MotionDone pops (remotes:
0/40) - MoveToManager's retail wait-for-anims gate
(BeginTurnToHeading's MotionsPending check) never opened.
ROOT CAUSE (found via a production-faithful repro test - the original
suite force-drained the queue, masking it): the R3 port MISIDENTIFIED
retail's StopCompletely_Internal body. It is NOT a physics velocity
zero - CPhysicsObj::StopCompletely_Internal (0x0050ead0) tailcalls
CPartArray::StopCompletelyInternal (0x00518890) which is
MotionTableManager::PerformMovement(type 5): an ANIMATION-side full
stop whose UNCONDITIONALLY-queued pending_animations entry is the
completable partner of the A9 pending_motions node
CMotionInterp::StopCompletely enqueues (raw @00527e90 between the
state writes and add_to_queue). Without the dispatch, every
StopCompletely (login/teleport SetPosition + every MoveToManager
PerformMovement head) left an orphan node with no completion - the
queue never drained at idle. (The R3 code comment claimed a register
row for the stand-in; none was ever added - porting the real mechanism
closes that violation without a row.)
Fix set (all retail-anchored):
- IInterpretedMotionSink gains StopCompletely() (default true = the
null-sink posture); MotionTableDispatchSink routes it to the R2
manager's already-ported type-5 op (StopObjectCompletely +
Ready-sentinel entry) + TurnStopped for the ObservedOmega seam.
- MotionInterpreter.StopCompletely calls DefaultSink?.StopCompletely()
at the exact retail slot (after the state writes, before
add_to_queue); the immediate set_velocity(Zero) is kept as the
documented physics-effect stand-in.
- PlayerMovementController ticks CheckForCompletedMotions after
UseTime - retail's per-tick CPartArray::HandleMovement slot
(0x00517d60 = MotionTableManager::UseTime = CheckForCompletedMotions
tailcall, called every tick from UpdateObjectInternal @005159a4).
NOTE: a first-cut per-tick apply_current_movement pump was tried and
REVERTED - retail's apply callers are all event-driven (hold-key,
HitGround/LeaveGround, ReportExhaustion), not per-tick; the remote
block's per-tick apply is a pre-existing adaptation outside this
fix's scope.
- The P1 autonomous-store family, completing the pin's port shape
(the gate landed in V5; the STORE side was missing):
(a) the unpack store (00509730: last_move_was_autonomous = wire
byte) in the GameWindow player branch - local player only for now
(remote interps have no WeenieObj, which A3 reads as IsThePlayer;
storing a remote's autonomous byte would mis-route their per-tick
apply onto the raw branch);
(b) input edges store =1 at the controller edge block - retail's
CPhysicsObj::DoMotion @00510030 / StopMotion @005100e0 /
TakeControlFromServer @006b32f4 input-boundary stores;
(c) section 2's per-frame velocity write now PRESERVES the flag
(V5's first cut stamped it per frame, the wrong altitude - retail
stores it at event boundaries only);
(d) InstallSpeculativeTurnToTarget stores false (models the wire
mt-6's unpack store; part of the AP-23 adaptation) so the
event-driven applies (e.g. HitGround mid-moveto) route interpreted
and cannot clobber the manager's dispatched motions with idle raw
state.
Tests: new ServerMoveToPosition_ProductionCompletionFeed_WalksToArrival
drives the controller under the PRODUCTION completion feed
(sequencer.Advance -> MotionDoneTarget) instead of force-draining -
this is the test that reproduced the live wedge (queue stuck at the
two A9 Ready orphans) and now proves the drain. Existing cutover tests
mirror the wire-path autonomous store before PerformMovement. Full
suite green: 3,957.

The local player now runs server MoveTos through the same verbatim
MoveToManager remotes got in V4. One commit, GameWindow + controller,
per the no-fan-out rule for coupled slices.
P1 gate (V0-pins.md P1, ported verbatim): CPhysics::SetObjectMovement
(0x00509690 @0050972e) drops any movement event whose wire autonomous
byte is set when the addressed object IsThePlayer - ACE's self-addressed
MoveToState reflection (MovementData.cs:162 IsAutonomous=1) never
reaches unpack_movement, which is what makes the retail unconditional
unpack-head interrupt safe. Gate placed AFTER the sequence gates
(retail order). The stale "ACE follows every mt=0x06 with an mt=0x00"
comment block dies with the code it excused (its causal story was
pre-#75; refuted in V0-pins P1).
Run-rate re-anchor (P1 contingency NOT needed - no AD row): the echo
tap ApplyServerRunRate is deleted outright. Both retail feeds already
exist: PlayerDescription skills via SetCharacterSkills (K-fix7) into
InqRunRate (preferred by apply_run_to_command/get_state_velocity), and
the mt-6/7 my_run_rate wire write (M13) now performed for the player by
the shared RouteServerMoveTo. The tap's InterpretedState.ForwardSpeed
overwrite was a pre-R3 mechanism that fought the ported machinery.
B.6 auto-walk deleted wholesale (~330 lines): fields, Begin/End/
DriveServerAutoWalk, IsServerAutoWalking, AutoWalkArrived, the
autoWalkConsumedMotion gates, the #69 turn-dir edge synthesizer, and
the relocated AutoWalkArrivalEpsilon/AutoWalkTurnRateFor constants
(AD-26 retired - the invented 5/30-degree bands are gone; arrival is
retail's distance predicate; turn-first is the TurnToHeading node).
TS-36 retired: Motion.InterruptCurrentMovement binds to
MoveTo.CancelMoveTo(ActionCancelled). Movement-key edges (ctor-default
params carry the 0x8000 CancelMoveTo bit), Shift (set_hold_run
interrupt:true), jump(), StopCompletely, and teleport all cancel a
running moveto through the retail chain - verified by controller-level
tests, not assumed.
MoveToComplete seam WIDENED to natural completion (Core): retail's
BeginNextNode empty-queue completion is inline CleanUp+StopCompletely
(raw @00529d47) and notifies nothing - the client-addition seam had to
fire there (both sticky and non-sticky exits) or AD-27's deferred
close-range Use/PickUp re-send never fires. Never fires on CancelMoveTo.
AD-27 re-anchored from the deleted AutoWalkArrived event.
InstallSpeculativeTurnToTarget rewired through the player's manager
(retail 9a/9b client-initiated shape): close-range -> TurnToObject,
far -> MoveToObject; AP-23 radius buckets + the #77 CanCharge
prediction survive as the params source (row re-anchored).
Per-tick: MoveTo.UseTime() at the old DriveServerAutoWalk slot
(provisional until R6, per the plan's placement decision); the P4
player-side TargetTracker twin (fields + pre-Update feed) mirrors the
remote adapter (AP-79 row widened). HitGround dual-call added on the
player landing edge AND the remote landing site - the latter closes a
V4 wiring-contract gap the adversarial review caught (retail 2d order:
minterp then moveto; without it a landing NPC's moveto never re-arms).
Also from the adversarial review: the mt-8 unresolvable-target degrade
now performs retail's params.desired_heading = wire_heading
substitution (decomp 2f case 8; invisible against ACE per P6, required
for the verbatim degrade); the V4 remote MoveToManager binding gets a
real curTime clock (the ctor stub advanced 1/30s per READ, skewing the
progress/fail-distance windows - note: the pending V4 NPC smoke ran on
the skewed clock); TS-33 row extended with the orientation-diff gap
(ApproxPositionEqual vs retail Frame::is_equal full-frame compare - a
stationary heading snap does not reach the wire; masked against ACE,
R7 outbound scope owns the fix).
MoveToMath gains HeadingFromYaw/YawFromHeading (the P5 scalar bridge
for yaw-authoritative bodies - the player's heading snap must write
Yaw, not the quaternion the controller re-derives every frame).
Tests: 3,956 green (+8). New: MoveToManagerCompletionSeamTests (arrival
fires once with None, no refire, cancel never fires, sticky handoff
order) + PlayerMoveToCutoverTests (EnterPlayerModeNow-shape rig: walks
to arrival with zero user input and zero MotionStateChanged frames -
the #75 invariant by construction; TurnToHeading rotates Yaw and snaps
exact; W-edge and jump cancel without firing complete). W6 edge suite
retargeted from the deleted echo tap to a direct apply pass (the
regression lives in ApplyInterpretedMovement, not the wire trigger).
Spec: docs/research/2026-07-03-r4-moveto/r4-port-plan.md section 3 V5.

Every remote's server-directed movement now runs the verbatim retail
MoveToManager. EnsureRemoteMotionBindings constructs it per remote with
the full V2 seam set (position/heading/velocity providers, the P4
TargetTracker adapter via setTarget/clearTarget storing the tracked
guid on RemoteMotion) and binds InterruptCurrentMovement ->
CancelMoveTo(0x36) - the retail interrupt chain (TS-36 remote side).
UM routing is retail's unpack_movement dispatch (0x00524440): the
head-interrupt + unstick fire for EVERY movement type, then mt 6/7
build MovementParameters.FromWire(raw bitfield - now surfaced by the
parser) + a MovementStruct (mt 6 resolves the target guid against the
entity table, degrading to MoveToPosition at the wire origin per the
plan's 2f; my_run_rate written from MoveToRunRate per @300603) ->
MoveTo.PerformMovement; mt 8/9 likewise via FromWireTurnTo; ONLY mt 0
flows through the interpreted funnel (the PlanMoveToStart seed is
DELETED - retail never routes MoveTo types through the interpreted
state copy).
Per tick: the P4 tracker feeds HandleUpdateTarget(Ok/ExitWorld) from
the live entity table, then UseTime runs the manager's steering/
arrival/fail handlers, then apply_current_movement recomputes velocity
- the same shape ordinary locomotion uses. The legacy driver branches,
the stale-destination timer, and the ClampApproachVelocity band-aid
are gone; arrival now uses retail cylinder distance (watch melee-range
stop distance in the visual pass).
DELETED: RemoteMoveToDriver.cs + its tests (OriginToWorld relocated
verbatim to MoveToMath; the B.6 auto-walk's two surviving constants
inlined into PlayerMovementController, dying with it in V5);
ServerControlledLocomotion.PlanMoveToStart + tests (PlanFromVelocity
survives - new AP-80 row); the RemoteMotion MoveTo capture fields.
Registers: AD-8/AD-9/AP-8/AP-9 retired; AP-79 (TargetTracker adapter,
retire R5) + AP-80 added.
Full suite green: 3,948 passed. Live smoke launched - NPC
chase/wander behavior pending user verification (recorded in the
session handoff).

The retail server-directed-movement brain (0x00529010-0x0052a987),
Core-only with every App dependency as a ctor/property seam for the
V4/V5 cutovers: node-plan builders for all four movement types
(TurnToObject's desired-heading clobber quirk VERBATIM; TurnToHeading's
immediate BeginNextNode - ACE's one-tick-late gap not copied),
PerformMovement (cancel 0x36 + unstick first), BeginNextNode with the
sticky handoff order (radius/height/tlid read BEFORE CleanUp),
BeginMoveForward (GetCommand walk/run cascade + stored-params
write-back + progress-clock seed), HandleMoveToPosition (chase arrival
dist <= distance_to_object per the adjudicated BN inversion; fail
distance -> 0x3D; progress >= 0.25 units/s over >= 1 s, incremental AND
overall; fail_progress_count write-only - retail has NO give-up
threshold and none was invented), HandleTurnToHeading (20/340 aux
deadband; the Ghidra-confirmed heading_diff mirror), HandleUpdateTarget
0x0052a7d0 (deferred-start: object moves wait for the first Ok
callback; retargets reset the progress clock without requeueing),
UseTime's initialized gate, InitializeLocalVariables per retail (flags
word + context_id zeroed, floats stale, FLT_MAX resets - not ACE's
transpositions).
TDD catch: default(Quaternion) is the ZERO quaternion, not identity -
a fresh manager's heading computations would silently read 90 degrees;
explicit IdentityPosition resets match the decomp's identity-Frame
semantics. Also pinned: retail's explicit double adjust_motion in
_DoMotion/_StopMotion; entry points never drain pending_actions (only
PerformMovement's cancel does) - re-issues must route through
PerformMovement, documented + tested.

MovementParameters gains the verbatim selection family:
GetCommand 0x0052aa00 (the walk-vs-run cascade INCLUDING the CanCharge
0x10 fast-path ACE dropped - retail's default can_charge=false + the
fast-path present, the A13+A15 canceling-pair trap avoided; inclusive
threshold edge per the raw), TowardsAndAway, GetDesiredHeading per the
live Ghidra decompile (fwd-towards 0 / fwd-away 180 / back-towards 180
/ back-away 0), FromWire/FromWireTurnTo (UnPackNet semantics, all 18 A4
masks round-tripped).
New MoveToMath: HeadingDiff per the live Ghidra decompile of 0x00528fb0
(the 360-diff NOT-TurnRight mirror + F_EPSILON 0.000199999995f - the
BN "arg unused" artifact corrected), HeadingGreater (the visible
TurnRight idiom), PositionHeading/Get/SetHeading reusing the codebase's
single yaw-heading convention (P5), CylinderDistance (PDB arg order;
planar-minus-radii shape documented as the interpretation - the raw's
x87 body is garbled; seam noted).
MovementType gains Invalid + retail 6/7/8/9; MovementStruct widened
(ObjectId/TopLevelId/Pos/Radius/Height/Params, additive); WeenieError

P1 (BLOCKER -> RESOLVED, no adaptation needed): retail's
CPhysics::SetObjectMovement (0x00509690) drops any movement event whose
wire AUTONOMOUS byte is set when the addressed object IsThePlayer -
BEFORE unpack_movement's unconditional head-interrupt ever runs. ACE's
mt-0 MoveToState echo is IsAutonomous=1 HARDCODED (MovementData.cs:162)
and only exists when the client itself sends a MoveToState (the
2026-05-14 'echo kills auto-walk' trace was the pre-#75 build whose
overlay leaked outbound packets - post-#75 there is no echo at moveto
start). acdream parses isAutonomous (UpdateMotion.cs:129) and consumes
it NOWHERE; MotionSequenceGate cites 0x00509690 in its own doc but
omitted this final branch. V-commits port the missing gate tail and the
verbatim head-cancel lands cleanly; the informal GameWindow
no-cancel-on-non-MoveTo note retires.
P3 (Ghidra-confirmed live, textual verdict independently identical):
heading_diff 0x00528fb0 HAS the TurnLeft mirror - 360-diff whenever the
turn command != TurnRight; the extraction's 'arg unused' was a BN
x87-setcc artifact (the W6b class). P2 Ghidra-confirmed:
get_desired_heading = fwd-towards 0 / fwd-away 180 / back-towards
180 / back-away 0. ghidra-confirmations.md holds both raw decompiles.
P4-P7 pinned per V0-pins.md. RemoteMoveToDriver's stale chase/flee
class-doc claim corrected (retail and ACE AGREE on the predicates).

User live report (the R3 visual pass): pressing W stopped the local
player instantly (retail observers saw run + rubber-band back — our AP
never moved); S/strafe appeared to work. The edge tracer + a
harness-with-echo repro converged on the funnel:
ApplyInterpretedMovement live-read InterpretedState.ForwardCommand
AFTER the style dispatch. The style dispatch SUCCEEDS against the real
MotionTableDispatchSink (GetObjectSequence Branch 1 style==target →
success — verified in the raw @298636), which gates the
ModifyInterpretedState write → InterpretedMotionState::ApplyMotion's
style branch resets forward_command to Ready UNCONDITIONALLY (raw
0051ea6c — our port is verbatim). Retail SELF-HEALS: its compiled
apply pass reads the axis fields into registers BEFORE the style call,
so the fwd dispatch re-applies the pre-reset command and the field
recovers within the pass — proven by our own 183-case live-retail
observer trace (the fwd dispatch carries the wire's RunForward after
the style dispatch on the same UM). The BN pseudo-C's apparent
post-style field reads at 0x528687 are decompiler rendering of hoisted
registers — the same artifact class as the A1 polarity inversion.
Under the live-field read, every apply pass (the ~10Hz ACE UM echo via
ApplyServerRunRate included) dispatched Ready and left the field
permanently Ready; the controller's per-frame get_state_velocity then
zeroed the body. The 183-case suite could not catch it: its
RecordingSink's return value doesn't mirror the real sink's
style-success, so the resetting state-write never ran under test.
Fix: entry-cache fwd/sidestep/turn commands+speeds (and the my_run_rate
read) before the style dispatch — restoring the S2a funnel's original
semantics through the W5 merge.
3 new regression tests bind the REAL sink over a real sequencer
(the masked condition): a full apply pass self-heals forward; 2 seconds
of held-W with echo cadence covers meters not centimeters; Shift
walk↔run toggling survives mid-transition echoes. Full suite: 3,734
passed. Temp diagnostics removed.

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

The two parallel DoInterpretedMotion implementations MERGE into one
verbatim pair (0x00528360/@305639): contact gate, StandingLongJump
state-only branch, Dead → RemoveLinkAnimations, the jump_error_code
double-check WITH the DisableJumpDuringLink 0x20000 leg (W2's TODO(W5)
resolved — MovementParameters now flows), ModifyInterpretedState
gating, CurCell-null tail, AddToQueue with the real ContextId;
StopInterpretedMotion's post-stop Ready node + raw-mirror RemoveMotion.
Legacy overloads + ApplyMotionToInterpretedState DELETED. The funnel's
public surface unchanged (183-case suite compiles + passes as-is).
DoMotion 0x00528d20 verbatim: cancel_moveto interrupt; SetHoldKey(key,
cancelMoveToBit) BEFORE adjust_motion; params re-default for the
interpreted call; combat-stance gates on the ORIGINAL id (Crouch/Sit/
Sleep → 0x3f/0x40/0x41; & 0x2000000 → 0x42 outside NonCombat); action
depth cap ≥6 → 0x45; raw mirror ORIGINAL id. StopMotion 0x00528530
mirror shape. StopCompletely 0x00527e40 with the A9 snapshot quirk
(motion_allows_jump on the OLD forward command, stashed in the queued
node) + the J9 fix (sidestep/turn SPEEDS untouched — the 1.0 resets
were a divergence). PerformMovement flushes zero-tick completions after
every dispatched op via the new CheckForCompletedMotions seam
(0x0050fe30) — bound App-side per entity (remotes via
EnsureRemoteMotionBindings, player at the sequencer bind site).
PORT DISCOVERY (not in the W0 pins): retail's DoInterpretedMotion
RESULT gates both add_to_queue AND the state write — a void sink let
the style dispatch's apply-only failure clobber ForwardCommand before
the forward axis read it, regressing 74/183 live-trace cases.
IInterpretedMotionSink.ApplyMotion/StopMotion now return bool
(documented on the interface with the raw anchors); one funnel
assertion corrected with raw-line citations (airborne ForwardCommand
ends at Falling under the fully-wired verbatim algorithm).
62 new gate-table tests. Full suite: 3,729 passed.
Implemented by a dedicated agent against the W0-pinned spec; seam
bound + suite independently re-verified by the orchestrator.

Core (dedicated agent, independently reviewed): HitGround 0x00528ac0 /
LeaveGround 0x00528b00 verbatim (creature+gravity gates, the
RemoveLinkAnimations seam — K-fix18's retail mechanism — velocity via
GetLeaveGroundVelocity with the autonomous flag, jump-state resets,
apply_current_movement re-sync); enter_default_state 0x00528c80 per A8
(fresh states, InitializeMotionTables seam, sentinel APPENDED without
draining pending_motions — pinned, Initted=1, LeaveGround tail);
Initted gates; the A3 IsThePlayer dual dispatch in
apply_current_movement / ReportExhaustion / SetWeenieObject /
SetPhysicsObject (a remote player routes INTERPRETED — the
ACE-divergence pin); set_hold_run 0x00528b70 + SetHoldKey 0x00528bb0
(XOR guard, None-only-from-Run); adjust_motion creature guard wired
(TS-34 retired); PhysicsBody.LastMoveWasAutonomous +
set_local_velocity(autonomous). Port discovery: retail's
apply_raw_movement 0x005287e0 / apply_interpreted_movement 0x00528600
ARE the already-shipped D6.2a/funnel functions — the dual dispatch
composes them instead of duplicating.
App cutover (orchestrator): the skipTransitionLink flag + both K-fix18
call sites DELETED (AP-74 retired). MotionInterpreter.DefaultSink routes
apply_current_movement's interpreted branch through the REAL funnel
dispatch when a sink is bound — so a remote's LeaveGround engages
Falling via the contact-gated funnel, replacing the forced SetCycle
(J19); the per-remote MotionTableDispatchSink is now PERSISTENT
(EnsureRemoteMotionBindings: DefaultSink + RemoveLinkAnimations +
InitializeMotionTables seams, idempotent from both the UM and
VectorUpdate paths; wire velocity re-applied after LeaveGround so it
stays authoritative). Player: seams bound to the player sequencer; the
controller's grounded→airborne EDGE now fires LeaveGround (jump()
clears OnWalkable and the same frame's transition detection fires it —
retail's order; walk-off-a-ledge gets the momentum fallback + link
strip it never had); the manual jump-block LeaveGround deleted;
LastMoveWasAutonomous set at the controller chokepoint (W6 refines).
Trace S8 re-expressed as the retail mechanism (Falling dispatch +
RemoveAllLinkAnimations = same final state the flag produced). 43 new
lifecycle tests. Registers: TS-34 + AP-74 retired; TS-38, AP-77, AP-78
added. Full suite: 3,665 passed. Live smoke: in-world clean.

JumpChargeIsAllowed 0x00527a50 (CanJump→0x49 before posture; Fallen +
Crouch..Sleeping→0x48), ChargeJump 0x005281c0 — now the ONLY place
standing_longjump arms (grounded Contact+OnWalkable + forward Ready +
no sidestep/turn, raw @305453-305466); the S2a-flagged side effect
inside contact_allows_move is DELETED (J6) with regression pins that
contact checks never touch the flag (the funnel's StandingLongJump
branch is local-player scope; the controller wires ChargeJump in W4/W6
— remotes never charge client-side, no interim regression).
jump_is_allowed 0x005282b0 full chain replaces the 15-line
approximation: IsFullyConstrained→0x47 (new PhysicsBody stub, TS-35)
BEFORE the pending-head peek (A2 ordering, pinned); head peek fires
whenever the queue is non-empty (no ACE Count>1 gate; nonzero
jump_error_code short-circuits the whole chain — test proves
JumpStaminaCost is never consulted); retail entry shape verbatim
(non-creature-weenie and gravity-off skip the ground gate; null
physics obj → 0x24 NOT 8 per A10); charge → MotionAllowsJump(fwd)
double-check → JumpStaminaCost gate (new IWeenieObject member,
always-affordable PlayerWeenie stub — TS-5 extended).
GetJumpVZ/GetLeaveGroundVelocity: epsilon corrected to retail's
0.000199999995f (was 0.001 — regression-pinned at extent 0.0005);
A5 shape (clamp 1.0, weenie-null 10.0f); A6 momentum fallback fires
only when ALL THREE components are sub-epsilon and overwrites all
three with global→local(m_velocityVector).
Jump 0x00528780: InterruptCurrentMovement no-op seam (TS-36, →R4
cancel_moveto), fires unconditionally; standing_longjump cleared ONLY
on failure (success keeps it — pinned). IWeenieObject.IsThePlayer()
(PlayerWeenie true) lands for W4's A3 dispatch.
51 new tests + 1 re-pin; superseded pre-W3 jump tests removed. Full
suite: 3,623 passed. Registers: TS-5 extended, TS-35/36/37 added.
Implemented by a dedicated agent against the W0-pinned spec; arming

MotionInterpreter implements IMotionDoneSink: pending_motions
(LinkedList<MotionNode>, AD-34 wording) + add_to_queue 0x00527b80 +
motions_pending 0x00527fe0 + MotionDone 0x00527ec0 verbatim (action-class
head → UnstickFromObject no-op seam (→R5 StickyManager) + BOTH states'
action-FIFO pops; head popped UNCONDITIONALLY — A7: never match-by-id,
params unread in this build) + HandleExitWorld 0x00527f30 (the raw
decompile's null-physics-obj branch would infinite-loop if translated
literally — adjudicated as retail dead code, documented on the method) +
is_standing_still 0x00527fa0 + MotionAllowsJump 0x005279e0 with the
A1-pinned literal blocklist (28-case boundary table test: Fallen blocks,
Falling passes — ACE's transposition NOT copied).
Queue producers wired into the funnel per the decomp anchors
(re-verified from the raw text): DispatchInterpretedMotion's success
path computes jump_error_code via retail's double-check shape
(motion_allows_jump(motion), then forward_command when non-action;
the DisableJumpDuringLink params leg is TODO(W5) — no MovementParameters
threaded yet) + add_to_queue; apply_interpreted_movement's turn-stop
re-queues the Ready node (@305766-305785 — the plan's producer #2 and #3
are the SAME site; StopInterpretedMotion's internal add_to_queue @305657
is W5 scope). ContextId=0 with TODO(W5): retail's own compiled code
reads an UNINITIALIZED local for it at this call site.
GameWindow: MotionDoneTarget now binds the entity's REAL consumer —
player via PlayerMovementController.Motion (new internal property),
remotes via RemoteMotion.Motion — resolved AT FIRE TIME (a remote's
RemoteMotion can be created after its first anim tick; an eager capture
would drop completions forever). Despawn runs BOTH layers' exit-world
drains (manager then interp) per §4. AD-36 narrowed (consumed for
creature-class; doors/statics recorder-only until R5).
51 new conformance cases incl. the end-to-end chain test:
MotionTableManager.AnimationDone → sink → interp pending head pops in
step. 183-case observer-trace + funnel suites green unchanged (queue
side effects additive). Full suite: 3,582 passed.
Implemented by a dedicated agent (MotionInterpreter side) against the
W0-pinned spec; producer placements + MotionAllowsJump branch algebra
independently reviewed against the raw decomp; GameWindow wiring by the
orchestrator.

InterpretedMotionState + the unified RawMotionState (LegacyRawMotionState
folded away) gain retail's action FIFO + ApplyMotion/RemoveMotion, ported
verbatim from the raw named decomp (0x0051e790/0x0051eb60 region, pc
293252-293703) including two genuine retail quirks pinned by tests and
independently re-verified against the raw text before commit:
- RawMotionState::ApplyMotion's RunForward (0x44000007) dead branch — a
cycle-class apply of literal RunForward writes NOTHING (retail encodes
run as WalkForward + HoldKey_Run on the raw state; same family as the
D6 apply_run_to_command early-return).
- InterpretedMotionState::RemoveMotion's exact-match-only TurnRight/
SideStepRight handling (left variants fall through to the style/
forward branches).
MovementParameters verbatim (A4 pin): 18 named flags per the absolute
mask table, ctor = 0x1EE0F expansion + distance_to_object 0.6 /
fail_distance FLT_MAX / speed 1 / walk_run_threshhold 15 / hold_key
Invalid — with the two ACE-divergence traps ported RETAIL-side
(can_charge FALSE where ACE defaults true; threshold 15.0 not 1.0).
MotionNode {ContextId, Motion, JumpErrorCode} (acclient.h:53293) — the
pending_motions node W2 consumes.
WeenieError renumbered to retail's numeric semantics (A10 table):
NotGrounded=0x24, GeneralMovementFailure 0x24→0x47, new 0x3f/0x40/0x41
combat-stance rejects + 0x42 chat-emote + 0x45 action-depth; the
airborne jump/action returns corrected 0x48→0x24 per the A10 sweep
(incl. jump_is_allowed's null-physics-obj 0x24-not-8 divergence from
ACE). Codes are local-only — wire untouched.
Outbound packer proof: RawMotionStatePacker unmodified; all 6
golden-byte RawMotionStatePackTests pass unmodified. TS-24 register row
updated (capability landed; outbound wiring still open).
Implemented by a dedicated agent against the W0-pinned spec; quirks,
scope, and suite independently verified. Full suite green: 3,531
(374+425+713+2015+4 pre-existing skips).

The funnel's retail-ordered dispatches now go directly into the entity's
motion-table stack via Motion/MotionTableDispatchSink (Core):
ApplyMotion → PerformMovement(InterpretedCommand), StopMotion →
PerformMovement(StopInterpretedCommand). No axis collection, no
single-cycle priority pick, no Commit pass, no HasCycle probe, no
Run→Walk→Ready fallback chain — GetObjectSequence 0x00522860 +
is_allowed decide (closes H4, H5-callers, H11-callers, H15, H17-carry).
Run-while-turning now blends for real: the turn is a Branch-4 modifier
combined over the untouched run substate (AP-73 DELETED from the
register).
AnimationSequencer gains the public PerformMovement passthrough (lazy
initialize_state + locomotion velocity synthesis on success — AP-75;
remote body translation via PositionManager.ComputeOffset depends on
CurrentVelocity) and InitializeState(); HasCycle DELETED (the miss
hazard is structurally gone — GetObjectSequence checks the cycle before
any surgery; new conformance test pins sequence+state untouched on a
miss).
GameWindow: sink swap with the TurnApplied/TurnStopped ObservedOmega
callbacks (H17 carried verbatim — register AP-76, retire R6); spawn +
door sites run retail's enter-world order (initialize_state installs
the table default, the wire's initial motion dispatches unguarded — the
L.1c fallback chains deleted); despawn drains the pending queue via
HandleExitWorld (MotionDone success:false per entry, 0x0051bda0).
5 new MotionTableDispatchSink conformance tests (lazy init, Branch-4
turn blend + callback, Case-B stop unwind, Case-A stop re-drive,
miss no-op). Full suite green: 3,462 passed.
Live smoke vs ACE: in-world, NPC emote/Ready UMs dispatching through
the new path, [MOTIONDONE] completions firing across entities — first
live proof of the Q3→Q4→Q5 chain. Zero exceptions.
Registers: AP-73 deleted; AP-76 added.

AnimationSequencer becomes a thin shim over the verbatim R2 stack:
SetCycle dispatches the style change (Branch 1) then the motion (Branch
2/3/4) through MotionTableManager.PerformMovement; PlayAction is the
same dispatch (actions rebuild via Branch 3; modifiers are Branch 4
physics-only combine_motion — the AP-73 turn-blend mechanism now runs
for real). CurrentStyle/CurrentMotion/CurrentSpeedMod are read-only
mirrors of MotionState (post-adjust_motion, signed mod). Lazy
initialize_state on first drive (retail lazy-create analog) keeps
undriven sequencers do-nothing.
DELETED legacy inventions (net -648 lines): the adapter fast-path
(replaced by Branch-2 fast re-speed: change_cycle_speed +
subtract/combine_motion), Fix B + IsLocomotionCycleLowByte (replaced by
remove_redundant_links on the pending queue — the retail mechanism the
2026-05-03 cdb trace pointed at), the stop-anim low-byte fallback
(replaced by get_link's reversed-key double-hop — retail's actual
backward-walk settle plays the windup link REVERSED), GetLink/BuildNode/
EnqueueMotionData + the G17 HasVelocity/HasOmega gate (add_motion sets
unconditionally), MultiplyCyclicFramerate + the G13 composite,
PlayAction's insert-before-tail machinery, SCFAST/SCFULL diagnostics.
KEPT at the adapter (register rows): the boundary adjust_motion remap +
locomotion velocity/omega synthesis (AP-75, retire R3-W6/R6), K-fix18
skip-link as post-dispatch RemoveAllLinkAnimations (AP-74, retire
R3-W4 when LeaveGround fires it).
GameWindow queue-drain wiring (the §4 G6 seam): each drained AnimDone
hook → manager.AnimationDone(true) (retail AnimDoneHook::Execute
0x00526c20 → Hook_AnimDone 0x0050fda0 chain), UseTime once per tick
(0x00517d57/0x00517d67); IMotionDoneSink bound to an
ACDREAM_DUMP_MOTION recorder (AD-36 — R3 rebinds to
MotionInterpreter.MotionDone).
Conformance: the 11-scenario pre-cutover trace suite (a6235a36) replays
green with six EXPECTED-DIFF annotations (double-hop walk-run routing,
reversed settle links, Branch-4 physics-only modifiers, Branch-1
style-change links, post-adjust mirrors) — everything unannotated is
byte-identical. Legacy suites repaired by a dedicated agent (fixtures
gain the retail-mandatory StyleDefaults + class-bit-tagged ids;
reflection state-poking replaced with real dispatch; zero category-D
regressions — the suspected cursor bug was a fixture class-bit gap),
plus two vacuously-passing tests fixed. Register: stale IA-4 deleted
(R1-P1 ported the negative-factor swap).
Full suite green: 3,458 passed (374+425+713+1946).
Closes H6, H7, H8, H9, H10-adapter, H16-wiring (r2-port-plan.md §3 Q4).

11 scripted scenarios (spawn idle, idle→walk link, walk→run cyclic-to-
cyclic, fast re-speed, backward-walk remap, stop-settle fallback, emote
action, K-fix18 skip-link, turn modifier, style change, link-drain
sentinel count) snapshotting the CSequence core's list state after every
SetCycle/PlayAction against the LEGACY adapter (fast-path + Fix B +
stop-anim fallback + G17 gate). These are the parity bar for the Q4
PerformMovement cutover — intentional post-cutover changes get
EXPECTED-DIFF annotations, everything else must stay byte-identical.
Notable pre-cutover behavior captured: the S6 link-before-link stacking
(old reversed link kept mid-drain while the settle link appends behind).
Adds the internal AnimationSequencer.Core test seam.

Ports retail's MotionTableManager (0x0051bxxx; r2-motiontable-decomp.md
§11) above the Q2 CMotionTable: add_to_queue 0x0051bfe0 (append +
immediate collapse), remove_redundant_links 0x0051bf20 (TAIL-ANCHORED
single scan, NOT ACE's restructured loop — cycle-tail block mask
0xb0000000 = STYLE|MODIFIER|ACTION, style-tail 0x70000000 =
CYCLE|MODIFIER|ACTION; the decomp's prose gloss of those masks was
imprecise, the literal constants are ported), truncate_animation_list
0x0051bca0 (zero NumAnims IN PLACE from the tail through the matched
node's successor + CSequence.RemoveLinkAnimations), AnimationDone
0x0051bce0 (counter-driven countdown chain: one call can pop MULTIPLE
entries; action-class pops MotionState's action FIFO; drained-list
counter reset), CheckForCompletedMotions 0x0051be00 / UseTime (zero-tick
sweep, success hardcoded true), initialize_state 0x0051c030 (0x41000003
sentinel), HandleEnterWorld/HandleExitWorld drains (MotionDone
success:false; enter also strips link anims), PerformMovement 0x0051c0b0
(error codes 7 / 0x43 / 0; StopCompletely queues the Ready sentinel
UNCONDITIONALLY).
IMotionDoneSink is the R2 seam standing in for CPhysicsObj::MotionDone —
R3 binds MotionInterpreter.MotionDone (r2-port-plan.md §4 contract).
This queue + remove_redundant_links IS the retail mechanism our old
'Fix B' rapid-motion collapse approximated — Q4 deletes Fix B and routes
SetCycle/PlayAction through PerformMovement.
47 conformance tests: countdown-chain tables, truncate blocked/allowed
matrices for both masks, zero-tick vs counter sweep, world drains, the
walk-run-walk-run collapse trace, the 2026-05-03 walk-to-run golden
(both nodes queued, truncate not firing), PerformMovement error matrix.
Register: AD-34 extended (pending_animations managed LinkedList);
AD-35 added (NotHandled sentinel vs retail's dead-code pointer-leak
default case).
Implemented by a dedicated agent against the committed Q3 spec; diff
scope, mask semantics, truncation range, counter reset, and
PerformMovement paths independently verified against the decomp raw
text before commit. Build + full suite green (3,447 passed).

Style/Substate/SubstateMod + the two independent MotionList chains with
retail's exact disciplines: modifier PUSH-FRONT stack
(add_modifier_no_check 0x00525ff0; add_modifier 0x00526340 refusing
duplicates AND the current base substate; remove_modifier by node;
clear_modifiers) and action TAIL-APPEND FIFO (add_action 0x005260a0;
remove_action_head 0x00526120 returning the popped motion, 0 when
empty; clear_actions). Deep-copy ctor clones both chains (Q0-pins
A4-#5: re_modify's snapshot is a termination bound, never shared).
11 discipline-table tests. Next: Q2 (CMotionTable + free functions —
the GetObjectSequence dispatcher).

- 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).

The adapter keeps its full public surface (every consumer compiles
unchanged) while the internals move to Motion.CSequence:
DELETED (legacy invented mechanisms, per the R1 gap map + Phase R
mandate): the AnimNode class + adapter queue/_currNode/_firstCyclic/
_framePosition, the ACE-fabricated FrameEpsilon boundary math, the
safety=64 advance cap, ClearCyclicTail surgery, the stale-head
_currNode relocation block, per-node IsLooping/Velocity/Omega, the
adapter-side AdvanceToNextAnimation/ApplyPosFrame/ExecuteHooks, the
per-node !IsLooping AnimationDone gate (now the core's list-structure
head != first_cyclic gate, G5).
REHOSTED: SetCycle rebuild = RemoveCyclicAnims (+ClearAnimations for
K-fix18) + retail add_motion appends (framerate-only AnimData scaling,
G10 loop membership: the LAST appended node is the cyclic tail) + Fix B
via RemoveAllLinkAnimations (the core's snap-forward IS Fix B's
behavior); Advance = core.Update(dt, null) with hooks flowing through
an IAnimHookQueue adapter into the existing ConsumePendingHooks drain;
fast path = core.MultiplyCyclicAnimationFramerate + the adapter-level
velocity rescale (R2's change_cycle_speed composite stand-in, G13).
Kept byte-identical: adjust_motion remap, GetLink + stop-anim fallback,
K-fix18, velocity synthesis, SlerpRetailClient, the #61 render-side
clamp, SCFAST/SCFULL diagnostics.
Tests: 2 updated with decomp citations — the reverse-start boundary now
pins retail's bare-int HighFrame+1 (0x00525c80, no epsilon, G1); the
root-motion accumulation test pins the inert-stub state pending P6's
Frame wiring (G7). All 44 sequencer tests + the 56 core tests + full
suite green (3346).
Implemented by a dedicated agent against the P5 spec; diff + tests
reviewed, suite re-verified before commit.

The CSequence frame-advance core (gaps G3/G4/G5/G6/G8/G9/G19),
ACE-verified skeleton + retail constants + the P0-pinned leftover carry:
- update_internal (0x005255d0): frame_number += framerate*dt; overshoot
clamps to the RAW high/low frame with leftover-time computation +
animDone; the pose/physics/hook triple fires for EVERY crossed integer
frame (ascending fwd / descending rev, strict > < boundaries, NO
epsilon, NO safety cap); AnimDone is a LIST-STRUCTURE gate (head !=
first_cyclic) queuing the global AnimDoneHook; iterative loop carries
the leftover into the next node (P0 pin — a lag spike fast-forwards
through multiple queued nodes in one tick).
- advance_to_next_animation (0x005252b0): four pose ops per transition
(subtract1 outgoing @ current frame + residual physics; step — fwd
wraps to first_cyclic, REVERSE wraps to the LIST TAIL, asymmetric by
design; reseed from the incoming direction-aware boundary; combine
incoming + physics). Pose ops run in BOTH directions — ACE's
framerate-sign gates are ACE-isms, decomp is unconditional modulo the
degenerate-framerate guard.
- update (0x00525b80): non-empty -> update_internal + apricot; empty +
frame -> accumulated-physics free motion (G8).
- execute_hooks (0x00524830): direction filter (Both or match) QUEUING
into the IAnimHookQueue host seam (stands in for CPhysicsObj.anim_hooks
+ the AnimDoneHook singleton; drain placement moves in R6). Null part
frame guarded (documented safe divergence vs retail's latent deref).
- FrameOps.Combine/Subtract1: the AFrame pose composition (verified
math from the pre-R1 port, now against DatReaderWriter Frame).
10 conformance tests: single-tick goldens, exact-integer boundary
sit (the old #61 flash class), cyclic wrap without AnimDone,
link->cycle fast-forward proving hook order (link hooks -> ANIMDONE ->
cycle hooks) AND the carry, reverse descending hooks with the OOB
high+1 start, reverse tail-wrap, zero-framerate physics-only,
empty-list free motion, pos-frame root motion into the caller Frame,
apricot trim via update. Full suite 3346 green.
R1 remaining: P5 (adapter cutover — AnimationSequencer rehosted on the
core, legacy epsilon/stale-head/safety-cap DELETED) + P6 (root-motion
wiring + API narrowing).

CSequence (Core/Physics/Motion): anim-node list with retail's exact
cursor semantics —
- append_animation (0x00525510): first_cyclic slides to the JUST-
APPENDED node on EVERY call (the cyclic tail is always the last
appended node); curr_anim seeds to head + get_starting_frame only
when null; unresolvable anims discarded (G10);
- remove_cyclic_anims (0x00524e40): removed curr_anim snaps BACK to
prev at get_ending_frame (or 0.0); first_cyclic = new tail;
- remove_link_animations/remove_all_link_animations (0x00524be0/
0x00524ca0): removed curr_anim snaps FORWARD to first_cyclic at
get_starting_frame (G11);
- apricot (0x00524b40, PDB-verified retail name): consumed-head trim
bounded by curr_anim AND first_cyclic;
- clear (0x005255b0) resets placement fields too — raw body is
authority over the gap map's G20 note;
- sequence-level velocity/omega with set/combine/subtract (G12);
- multiply_cyclic_animation_fr touches framerates ONLY (G13 —
velocity rescale belongs to R2's change_cycle_speed composite);
- placement frame family + floored accessors (G14).
Register: AD-33 (double vs x87 long double frame_number, G15),
AD-34 (managed LinkedList vs intrusive DLList).
17 list-surgery state-table tests; 39 total R1 tests green.

own autonomous echoes).

implements); blocked non-action motions take the apply-only path —
retail's real mechanism behind K-fix17's 'airborne remotes keep
their cycle' empirical guard.
- contact_allows_move REWRITTEN VERBATIM from the real 0x00528240
(pseudo-C 305471): Falling/0x40000011 + turns always allowed,
non-creature weenies + no-gravity bypass, else Contact+OnWalkable.
The previous body conflated jump_charge_is_allowed (0x00527a50)
posture checks — the 2026-06-04 deep-dive divergence, now retired.
Six tests that pinned the misattributed behavior corrected
(grounded posture does NOT block motion; airborne accepts
Falling/turns only).
- IWeenieObject.IsCreature (default true) for the gate's non-creature
bypass.
Conformance harness (the user-requested 'prove it equals retail'
apparatus, layer 1): RetailObserverTraceConformanceTests parses the
LIVE cdb trace of a retail observer (Fixtures/l2g-observer-trace.log,
captured via tools/cdb/l2g-observer.cdb) into 183 golden cases —
each [MTIS] input state replayed through our funnel must produce
retail's exact [DIM] dispatch sequence. 183/183 conformant, including
the airborne jump case (replayed contact-free; pre-gate vs post-gate
accounting + HitGround second-pass truncation documented in-test).
13 synthetic funnel tests cover the branches the trace missed
(actions, stamps, longjump, sidestep).
GameWindow integration (S2b) follows; funnel not yet wired.

Port retail's three-stamp inbound gate for 0xF74C UpdateMotion:
- MotionSequenceGate (Core/Physics): CPhysicsObj::is_newer (0x00451ad0)
wraparound u16 compare, verbatim per ACE PhysicsObj.is_newer (the BN
pseudo-C setcc returns are garbled; ACE + branch structure are the
oracle). Gates: INSTANCE_TS at dispatch (stale incarnation drops
before any stamp is touched), MOVEMENT_TS strictly-newer (stamped
BEFORE the server-control check, per CPhysics::SetObjectMovement
0x00509690), SERVER_CONTROLLED_MOVE_TS drop-when-stored-newer.
- Seed from CreateObject's PhysicsDesc timestamp block (index 1 =
ObjectMovement now parsed; ACE WorldObject_Networking.cs:411-420
order) — without seeding, entities whose movement sequence is past
0x8000 at spawn would drop every UM against a zero stamp.
Adopt-on-first / advance-only-after, so the #138 rehydrate replay of
retained spawns cannot regress live stamps.
- UpdateMotion + EntitySpawn now carry instance/movement/serverControl
sequences + isAutonomous (was parsed-past; isAutonomous feeds the
S2 funnel's last_move_was_autonomous). Gate wired at the top of
OnLiveMotionUpdated before any state mutation; [UM_STALE] diag under
ACDREAM_DUMP_MOTION / ACDREAM_REMOTE_VEL_DIAG; gate dropped with the
entity on DeleteObject.
Register: AD-32 added (adopt-newer-incarnation instead of retail's
QueueBlobForObject); TS-26 updated (UM side closed, UP side open).
Deviation map: docs/research/2026-07-02-inbound-motion-deviation-map.md.
19 new gate tests + parser coverage; full suite 3276 green.

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).

Ports the three retail outbound-movement packers verbatim (decomp-derived
golden bytes, confirmed via the Ghidra bridge, cross-checked vs holtburger):
- D1 — RawMotionState::Pack (0x0051ed10): new AcDream.Core.Physics.RawMotionState
data type (11 fields + actions, retail defaults) + RawMotionStatePacker that
sets a flag bit only when the field DIFFERS from its default. MoveToState.Build
now takes a RawMotionState instead of presence-based nullable params, so the
over-sent forwardSpeed=1.0 / currentHoldKey=None / default per-axis holdkeys are
no longer emitted. num_actions packs into bits 11-15 (not "bits 11-31").
- D3 — MoveToStatePack::Pack (0x005168f0) trailing byte =
(standingLongjump ? 0x02 : 0) | (contact ? 0x01 : 0); explicit contact/
standingLongjump params (standingLongjump=false honestly until the feature lands).
- D4 — JumpAction rewritten to retail JumpPack::Pack (0x00516d10): extent,
velocity, full Position, four u16 timestamps, align. Removed the spurious
objectGuid/spellId u32s; Position is now packed (it was absent). Body 56 bytes.
- Position::Pack (0x005a9640) / Frame::Pack (0x00535130) verified already-correct
(cellId, origin xyz, quaternion wxyz); locked with a golden test, no change.
GameWindow callers adapted minimally: build the RawMotionState from the existing
MovementResult values (behavior preserved except the intended D1 omissions) and
pass cellId/position/rotation to the Jump send. Pre-existing MotionInterpreter
placeholder struct RawMotionState renamed LegacyRawMotionState (D6/Phase-2 scope,
pure rename) to free the name for the retail-faithful type.
D5 audit: confirmed a real divergence — retail SendMovementEvent (0x006b4680)
stamps only last_sent_position_time after an MTS while SendPositionEvent
(0x006b4770) stamps all three; acdream's NotePositionSent stamps all three on
both paths. Left unchanged (comments added at both call sites), recorded as
register TS-33, deferred to a dedicated cadence-port slice.
Tests: RawMotionStatePackTests / MoveToStateGoldenTests / JumpActionTests /
PositionPackTests + updated MoveToStateTests / AutonomousPositionTests. Full
suite green (Core.Net.Tests 372, full solution 3228 passed / 4 pre-existing skips).
Register: TS-24/TS-25 refreshed (packer now supports actions/style; runtime
emission still deferred), TS-33 added. Roadmap L.2b shipped note added.

Splits MotionCommandResolver's single ACE-modern lookup into an
IMotionCommandCatalog seam with two implementations:
- AceModernCommandCatalog (runtime default): built cleanly from the
DatReaderWriter MotionCommand enum (mirrors ACE + local DAT MotionTables)
with a documented class-priority tiebreak. The old blind 0x016E-0x0197
per-range override is DELETED — verified the ACE matrix (LifestoneRecall
0x0153 to 0x10000153, MarketplaceRecall 0x0166, AllegianceHometownRecall
0x0171, OffhandSlashHigh 0x0173) resolves correctly straight from the enum
with no override. Stale shift-start comment corrected to SnowAngelState
(0x43000115 to 0x43000118), not AllegianceHometownRecall.
- Retail2013CommandCatalog (conformance/reference): full verbatim extraction
of command_ids[0x198] at 0x007c73e8 (acclient_2013_pseudo_c.txt:1017259-1017667),
direct wire-low to full index lookup. 408 entries, anchors verified against
source ([0x150]=0x10000150, [0x153]=0x09000153, [0x197]=0x10000197).
MotionCommandResolver.ReconstructFullCommand stays a static facade delegating
to an AceModern singleton — all ~10 runtime callers unchanged.
Removing the override exposed a pre-existing bug: CombatAnimationPlanner's
late-combat command block uses 2013 numbering, not ACE/DRW. Corrected the one
catalog test assertion pinned to the override's output (wire 0x0170 to
0x09000170 IssueSlashCommand, its true DRW identity) and filed the planner bug
as #159 rather than silently patching out-of-scope code.
Tests: +catalog matrices (ACE/2013), class-priority collisions, boundary
cases, real-DAT availability (gap-doc hit counts reproduced). Build + full
suite green (Core.Tests 1718, no regressions).

An OPEN door (ETHEREAL_PS 0x4 set on Use) still stopped the player with a
residual threshold block after the collision sweep, despite swinging open
visually.
The resolver runs two collision passes per step: the main sweep and a
step-down (foot-sphere "is there floor?") sub-pass. acdream tested the
ethereal door in BOTH; the main pass cleared it (BSPQuery Path 1 + the
Layer-2 override) but the step-down pass had no escape, leaving a Collided
result at the sill -- the "can-sized cylinder on the ground threshold".
Retail's CPhysicsObj::FindObjCollisions (pc:276795-276806) SKIPS an ethereal
target when sphere_path.step_down != 0 -- it only tests it in the main pass.
So an open door is fully passable everywhere; the swung panel's position is
irrelevant (ethereal = no collision; the swing animation is purely visual).
Port that branch verbatim: an ethereal-for-this-test target (target state &
0x4, OR mover-ethereal vs a non-static target) is `continue`d when
sp.StepDown is set.
Live-verified (user confirmed): the door now blocks 0x while open (0x1000C),
still blocks while closed (0x10008); pre-fix it blocked 217x while open.
Core suite green (1595/0).
(An earlier "animate the door collision" theory was wrong and dropped -- if
collision tracked the swung panel you'd bump the panel in its open position,
which retail does not do. The user caught it.)
