QueryModelDescriptor

How a query model can be queried on one entry: the answer GET …/schema gives to agents and the view engine.

It publishes conclusions, never storage vocabulary: every listed operator, sort, group and function is admitted when used on its own, anything unlisted is rejected; combination rules are in constraints. Values, scopes and policy conditions may still reject a query at run time, with a structured violation. It exposes no physical names and does not depend on the caller, so it is cacheable; version is a hash of its content and doubles as the ETag.
