dccd700991 feat(physics): R5-V5 — MovementManager facade owns each entity's interp+moveto pair
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).

f423884bd1 feat(physics): R5-V4 behavioral slice — head stance dispatch (all mt) + #164 autonomy bit + mt-0 wire flags
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.

Conformance: ChaseArm_WithStanceChange_AppliesStanceBeforeTheChase
(harness mirrors the routing-head dispatch) +
Actions_ReplayCarriesAutonomyIntoTheInterpretedList. Suite 4041 green.

699669502c fix(#171): sticky deep-overlap back-off sign pin — the runaway-to-center (gate-2 residual)
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.
Conformance: StickyManagerTests.AdjustOffset_DeepOverlap_BacksOff_
RateLimited. Full suite 4039 green.

5bd2b8bc8b fix(#171): R5-V3 — bind sticky melee (StickyManager live) + real arrival radii
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).

1051fc83c6 fix(#170): armed moveto always ticks UseTime — the SERVERVEL branch starved the chase
The "sustain the run" residual. The handoff's "Ready stop-node backlog
drains a beat slower than retail" framing was DISPROVEN: a new full-stack
offline harness (RemoteChaseEndToEndHarnessTests — real MoveToManager +
MotionInterpreter + AnimationSequencer + MotionTableDispatchSink + the
manual omega integration, wired field-for-field like
EnsureRemoteMotionBindings and ticked in TickAnimations' exact phase
order) proves the Core turn/run/drain pipeline healthy: the chase turn
completes in <1 s both directions, BeginMoveForward installs per arm, the
run sustains across re-arms and attack swings, and pending_motions fully
empties (retail cdb invariant add_to_queue == MotionDone).

The real mechanism (launch-drainq.log, corrected per-guid attribution —
the previous session's timeline mis-attributed [mvto] lines that fire in
the network phase): funnel per chasing scamp was 16 mt-6 arms -> 11
dispatched turns -> ONE BeginMoveForward. Any NPC receiving
UpdatePositions gets HasServerVelocity=true (synthesized from position
deltas even when the wire carries no velocity), and the grounded per-tick
branch routed those to the SERVERVEL leg, which SKIPS
MoveToManager.UseTime — [npc-tick] literally logged
"branch=SERVERVEL (skips UseTime) mtState=MoveToObject". The armed
moveto was starved for exactly the duration of the server-side chase:
legs stayed in Ready while the body glided on synthesized velocity (the
#170 slide); the manager only woke in UP-silent gaps (creature stopped
server-side) and its stale-heading turn was interrupted by the next UM
before reaching BeginMoveForward.

Retail runs MovementManager::UseTime UNCONDITIONALLY every tick
(CPhysicsObj::UpdateObjectInternal 0x005156b0, call @0x00515998) and has
no wire-velocity leg-driver anywhere; between UPs a moveto-driven body
translates from the motion state (get_state_velocity) with UP hard-snaps
correcting drift. Fix: an armed moveto (MovementTypeState != Invalid)
always takes the MOVETO leg; SERVERVEL remains only as the legacy
fallback for entities without a moveto (scripted paths / missiles).

Register: TS-41 (the narrowed SERVERVEL stopgap), TS-42 (drain-order
divergence also pinned this session: acdream drains AnimDone->MotionDone
AFTER HandleTargetting/MoveTo.UseTime; retail's process_hooks
@0x00512d3d runs BEFORE TargetManager/MovementManager in
UpdateObjectInternal — one frame of extra latency, R6 scope).

New conformance: RemoteChaseEndToEndHarnessTests (3 scenarios + theory)
+ RemoteChaseDrainBisectTests (the drain-chain pin; its first run also
demonstrated the TS-40 InWorld=false link-strip wedge shape — harness
bodies must replicate the live RemoteMotion construction).

ISSUES #170 updated (awaiting user visual gate; probes stay until then);
handoff doc superseded-note added.

3d89446d98 feat(physics): R5-V1 — port PositionManager/Sticky/Constraint + TargetManager (Core, unwired)
The retail movement-manager family the R4 MoveToManager port left as
do-not-invent seams (decomp §9f/§9g). Faithful C# ports of retail's
PositionManager facade + StickyManager + ConstraintManager + the
TargetManager voyeur system, with full conformance tests. NO wiring yet
— purely additive, no behavior change. Wiring (retiring TS-39 sticky +
AP-79 target adapter) is R5-V2/V3.

New Core classes (src/AcDream.Core/Physics/Motion/):
- StickyManager (0x00555400): follow-a-target steering. adjust_offset's
  dense x87 mush decoded via ACE (StickyRadius 0.3, StickyTime 1.0,
  follow speed ×5 / fallback 15) — speed-clamped signed-distance steer +
  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/.

b3decdfac6 feat(R4-V5): LOCAL PLAYER cutover - B.6 auto-walk DELETED; P1 autonomous gate ported; TS-36 bound (closes M1-local, M9, M10, M17; retires TS-36, AD-26; re-anchors AD-27, AP-23)
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.

addc8e97a8 feat(R4-V2): MoveToManager verbatim - all 33 members + conformance harness (closes M1/M3/M4/M5/M6/M10/M14-core)
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.

101 new conformance tests incl. three end-to-end scripted drives
(chase turn->run->walk-demote->arrive; flee; frozen-heading
TurnToObject through retarget). Full suite: 3,961 passed.

Implemented by a dedicated agent against the V0-pinned spec; scope +
suite independently verified.

e0d2492cbb feat(R4-V1): command-selection family + state widening (closes M2-mechanics, M11, M12, M15)
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
+= 0x0B/0x36/0x37/0x38/0x3D with retail-meaning doc comments.

148 new conformance tests. Full suite: 3,860 passed.

Implemented by a dedicated agent against the V0-pinned spec; scope +

8664959152 feat(R3-W1): retail state completion — action FIFOs, MovementParameters, MotionNode, WeenieError renumber (closes J2, J16-codes)
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).

d82f07d4e5 feat(R2-Q5): RemoteMotionSink DELETED — funnel dispatches straight into PerformMovement; AP-73 retired
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.

aa65990a1d feat(R2-Q3): verbatim MotionTableManager — the pending-animation queue (closes H3, H15-core)
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).

98f58db913 feat(R2-Q2): verbatim CMotionTable — the GetObjectSequence dispatcher
CMotionTable (Core/Physics/Motion, 692 lines) wrapping the dat
MotionTable, per r2-motiontable-decomp.md + Q0 pins:

- GetObjectSequence (0x00522860): entry guards; modifier-class no-op
  fast path; Branch 1 style-change (exit link + style link +
  default_style double-hop + re_modify); Branch 2 cycle (UNCONDITIONAL
  default-style retry per label_522ae6, is_allowed gate, same-substate
  re-speed fast path = ChangeCycleSpeed + SubtractMotion(old) +
  CombineMotion(new), clear-modifiers bit0, direct-link vs !SameSign
  double-hop, A2 signedSpeed, outgoing-modifier re-registration,
  re_modify, outTicks per A3); Branch 3 action (direct link OR the
  4-layer out-and-back with the base cycle re-added at the OLD
  substate_mod; outTicks WITHOUT ACE's double-count, A4-#1); Branch 4
  modifier (PHYSICS-ONLY CombineMotion + AddModifier stop-then-re-add —
  the AP-73 retirement mechanism).
- get_link (A1 pin: either-negative -> swapped keys — the adapter's
  field-validated port re-homed), is_allowed (Bitfield & 2; A5
  CONFIRMED on DatReaderWriter 2.1.7), re_modify (deep-copy snapshot
  termination bound), StopSequenceMotion, SetDefaultState,
  DoObjectMotion/StopObjectMotion/StopObjectCompletely (A4-#4 return).
- Free functions: AddMotion (UNCONDITIONAL velocity/omega set — the
  G17 core), CombineMotion/SubtractMotion (physics-only),
  ChangeCycleSpeed (verbatim incl. the A4-#2 retail gap), SameSign.

44 conformance tests pinning H1/H4/H5/H7/H8/H10-H14 + all Q0 pins,
incl. the run-while-turning gated-cycle -> Branch-4 physics-only test
(retail's actual turn-blend mechanism) and missing-cycle ->
sequence-untouched (retires the HasCycle fallback rationale).

Implemented by a dedicated agent against the Q2 spec; diff + key
branches reviewed, suite re-verified (3934 green) before commit.

2345da30e9 feat(R2-Q1): verbatim MotionState (gap H2)
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).

658b91d8aa feat(R1-P4): verbatim update_internal / update / advance_to_next_animation
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).

5138b8fb01 feat(R1-P3): verbatim apply_physics + Frame rotate/grotate
- CSequence.ApplyPhysics (0x00524ab0): copysign semantics — magnitude
  from the quantum arg, sign from the sign-source arg (call sites pass
  1/framerate + signed elapsed); origin += velocity*signed, then
  rotate(omega*signed).
- FrameOps.GRotate (0x005357a0): axis-angle quaternion (angle=|v|,
  half-angle sin/cos) PREMULTIPLIED onto the orientation — incremental
  rotation in WORLD space; |v|^2 < F_EPSILON^2 skipped.
- FrameOps.Rotate (0x004525b0): local rotation vector mapped through
  the frame's local->global rotation, then GRotate.

7 numeric conformance tests (copysign matrix, global-space composition,
local->global mapping equivalence, epsilon gate).

778744bf3e feat(R1-P2): verbatim CSequence container + list surgery
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.

1371c2a14c feat(R1-P0/P1): CSequence research base + verbatim AnimSequenceNode
P0 — research + pins: full CSequence-family verbatim extraction (1756
lines, per-function raw pseudo-C + cleaned flow, decomp line anchors),
ACE cross-reference (9 ranked divergences; headline: retail frame_number
is x87 long double — ACE's float is the worst case, our double the best
available; ACE's frame-boundary epsilon is an ACE fabrication, NOT
retail), current-sequencer map, and the R1 gap map (20 gaps, 13 keeps,
P0-P6 port order). Pinned the one decomp ambiguity (leftover-time carry
after advance_to_next_animation — ACE reading adopted; cdb confirmation
protocol recorded, non-blocking).

P1 — AnimSequenceNode verbatim (gap G1/G2/G16/G18):
- direction-aware BARE-INT boundary pair (get_starting_frame 0x00525c80 /
  get_ending_frame 0x00525cb0): reverse starts at high+1, ends at low —
  NO epsilon;
- multiply_framerate (0x00525be0) swaps low/high on negative factor;
- set_animation_id (0x00525d60) retail clamp order (high<0 -> num-1;
  low>=num -> num-1; high>=num -> num-1; low>high -> high=low);
- ctors with retail defaults (30f/-1/-1; AnimData copy + clamp);
- get_pos_frame null out-of-range (retail; ACE returns identity),
  floor double overload; get_part_frame same discipline;
- NO per-node IsLooping/Velocity/Omega — loop membership is list
  structure, physics accumulators live on the sequence (G16).

22 conformance tests (clamp table, boundary mirror table, swap
round-trip, bounds/floor semantics).
