Fresh-session handoff for the INBOUND (remote-entity) motion arc. Captures the
symptom (walk<->run transition without stopping = interpreter reacts too slowly
-> animation+position desync compounding through turns; plus sliding + stop
position errors), the root-cause hypothesis (acdream lacks retail's CMotionInterp/
CSequence motion-transition state machine: pending_motions/MotionDone), the
pre-paid research (2026-06-04 sequencer deep-dive, 2026-06-26 audit D7-D12), the
decomp anchors, the inbound code map, the /investigate-then-port plan, the
live-capture setup, and the discipline reminders (report-only, surgical
sequencer integration, decomp-verbatim). Prior outbound/local arc shipped clean
through d34721fa.
