A delivery runner receives the window and the door, nothing else
The recipient-roles table gives the delivery role three constraint types. Derive them from the example household and see that every health, schedule and device fact is withheld with a reason.

Passos
Derive what a delivery service may receive from the twelve facets of the example household.
deriveConstraintsBoth constraints come from one facet, the household's receiving rules; the facet's own value (the hour, the door) is not in the answer.
The child's allergy is the first withheld facet, because the role is not allowed that constraint type; the robot's firmware is withheld because no consent names a delivery service.
Resultado
You know that a role's allow-list in profiles/household/recipient-roles.json decides what travels, and that the answer carries facet ids and reasons, never values. Next: 081 derives the richest role, the meal planner.
