Cookwala / SDK and scenarios / 088

Your home as a grocer, a neighbour's robot and an insurer would see it

Run the same twelve household facts through three recipient roles and count what each receives: five constraints, three, none. No value ever appears: a budget cap is a cap, not your income.

Audience: home cook · Goal: Make people healthier, Robots for people · Level: beginner

Read first: /docs/HOUSEHOLD-CONTEXT/ /trust/

Steps

  1. The grocer: allergen block, labelling, delivery window, access point, budget cap. deriveConstraints

  2. A second robot: no-movement zone, pet-safe storage, available equipment. deriveConstraints

  3. An insurer: nothing from this household, which has no device fault facet. deriveConstraints

  4. In every answer the disclosed list is empty: no raw fact travelled to anyone.

Outcome

You can see, for any role, what leaves your home before it leaves. Next: 089 follows one allergy to two different recipients.

Command line
