The c2dc1a88 wedge fix paired every StopCompletely A9 node with a
completable motion-table type-5 entry via DefaultSink?.StopCompletely()
- but EnterPlayerModeNow called the initial SetPosition (whose teleport
idle is StopCompletely, R3-W6) BEFORE the sequencer/DefaultSink bind
block, so the login A9 node dispatched against a NULL sink and stayed
an orphan. Head-pop-any semantics mean a queue with one orphan never
reaches empty again (later completions just relabel the backlog), so
MotionsPending stayed true at every UseTime and the MoveToManager's
retail wait-for-anims gate (BeginTurnToHeading) never opened: every
server MoveTo armed (movingTo=True, Initialized=True, tracker fed,
node plan built) and the body never moved.
Pinned live by the [autowalk-gate] probe: type=MoveToObject init=True
contact=True motionsPending=True pm=[0x41000003] nodes=[TurnToHeading,
MoveToPosition] curCmd=0 - identical every half-second, forever.
Fix: the sequencer/sink bind block in EnterPlayerModeNow moves ABOVE
the initial physics Resolve + SetPosition (no data dependency - the
block only needs playerEntity/_animatedEntities). Teleport-arrival
SetPositions were already safe (sink long bound). Test rigs
(PlayerMoveToCutoverTests.MakeRig, W6EdgeDrivenMovementTests) mirror
the fixed order, and a new LoginQueue_DrainsToEmpty_UnderProductionFeed
test pins the invariant the probe caught: after login, pending_motions
must reach EMPTY under the production completion feed.
The [autowalk-gate]/[autowalk-feed] diagnostics stay in for the live
verify pass (TEMPORARY-tagged; strip when #5 closes). Full suite
green: 3,958.
