    "title": "An itinerary revision changes components whose supplier confirmations remain independent",

    "answer": "TO2 changes the day-two activity from A to B and pickup from W1 to W2, while retaining TO1's hotel H and nights. TO3 confirms the supplier's B acknowledgment for P/v2 but supplies no W2 transport confirmation; its W1 card belongs to the earlier version. Report the revised itinerary and each supplier state separately rather than assume one component's acknowledgment confirms the entire package or an unchanged hotel needs a new inferred booking.",
