Create Trip

First-message facts, using the canonical field types without checkout state.

Approximate IP coordinates used only to suggest an initial departure.

Where the visit came from before the first request: attribution only.

E.g. a ChatGPT visitor who opened a route page sends {"assistant": "chatgpt", "via": "/flights/...", "utm_source": "chatgpt.com"}. Brain stores it on the new trip; it is never a trip fact and never shown to the model. Unknown keys are ignored, values are trimmed and cut to 200 characters and a non-text value reads as unknown, so a new tag or an odd link never refuses a trip.

Create a conversation trip bound to the hotel checkout on screen.

Sent by the hotel's own standalone pages, which have no conversation trip and no mounted map. The trip is bound to the hotel search session the assistant's claim produced so later hotel_detail_question turns can read the stay's facts; no model, hotel search or supplier call is involved.
