Every preference was captured in the moment by whoever heard it, a butler's voice note, a concierge's typed line, and the AI organised them onto one profile owned by the group rather than any single property. Before he arrives in Paris, the duty manager reads the ninety-second living summary and sees the lily allergy carrying an AI flag as safety-critical. The Data Stream shows each preference attributed to the colleague who logged it and the property where it was first heard, including the reconciliation of an old "high floor" note against his later "nothing above the third floor." He is met as the guest the group already knows, and he rebooks Christmas before he checks out.
