Data

Where a value comes from

The model can fill any parameter of a skill; only the args of the submit calls and the APIs' authentication are out of its reach. What must be right — an amount, a price — is computed by the tenant: a skill's update: {price: …} guard, or its invoke. See Policies.

How long

On the server side, nothing expires on its own today: see Context.

What does not exist yet

No controlled origin (set_by), no data classes, no uniqueness (unique), no validity period (valid_for): the target describes them in Data.
