- NpcVisual emits position_changed signal during _physics_process - SimulationManager.synchronize_npc_position() writes active position into SimNPC state on movement, arrival, and navigation failure - WorldViewManager forwards position_changed and syncs before despawn/reload - SimNPC stores travel_target_position and has_travel_target as versioned state; NPCStateRecord v2 persists them with v1 migration - WorldViewManager.spawn_npc_visual() resumes travel for traveling NPCs via SimulationManager.request_current_travel() - WorldViewManager.despawn_npc_visual() syncs position before removal - WorldViewManager.reload_npc_visual() spawns a visual from persisted state without rerolling target selection - tests/npc_visual_lifecycle_test.gd proves unload/reload preserves action, target, reservation, position, RNG state, and checksum - simulation_state_serialization_test adds legacy v1 NPC migration test that does not invent an active travel target
