    "answer": "VS1 and VS2 support the approved and observed E substitution in slot two. VS3's B field is stale against that linked update and observation. Slot three remains assigned C in the plan and export, but its unlabeled observed prop cannot be identified as C from those intentions alone. Preserve assigned, observed and inventory-recorded states and request a slot-three check rather than infer every restocked item from the layout.",
