Port retail portal viewport projection and reveal behavior, preserve outbound combat style, drive remote and local grounded movement from authored CSequence root frames, and reuse the local prepared pose so animation hooks advance once.
User-verified portal, observer movement, combat stance, and short-tap locomotion gates. Release build passed with 5,767 tests and five intentional skips.

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.

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.
