Returns, for each requested destination country, the traveler-profile fields that compliance workflows require for a trip there. Requiredness is resolved from the processes mapped to that destination and the workflows attached to them — the same source of truth the trip-completeness check uses — so it reflects what will actually block a trip.

Fields whose requiredness depends on another profile value (e.g. only for certain nationalities) carry a conditions array; evaluate it against the traveler to decide whether the field applies.

Detecting changes: this endpoint returns a whole snapshot plus a version. Store the version and compare it on your next poll — if it is unchanged, nothing this endpoint reports has changed and you can skip reconciling. There is deliberately no since cursor: the underlying workflow links carry no timestamps and are hard-deleted, so a field that stopped being mandatory would leave no trace in a row-level feed.
