Guest preparation

Pre-trip intake
Starts with
Invited guest with pending preparation
Ends with
Verified preparation or an explicit mapping issue
An invited guest reviews the trip, supplies requested preparation details, and submits them for Operations verification without editing the itinerary or required work.
Operations sends a valid preparation invitation for an upcoming CIS.
This is the key moment: guest-submitted evidence does not change the CIS until Operations verifies its mapping.
Owns the human action and verifies the visible result.
Preserves identity, state, and record boundaries.
Only the authorized client context and actions
Why: complete and verify the human part of the journey
Bounded client, trip, and workflow state
Why: enforce trusted boundaries
The portal collects bounded guest evidence; Operations verifies it and the CIS remains the trip authority.
