QueryModelDescriptor

data class QueryModelDescriptor(val model: QueryModel, val version: String, val timeZone: String, val record: RecordDescriptor, val limits: LimitsDescriptor, val analysis: AnalysisDescriptor, val fields: List<FieldDescriptor>, val elements: List<ElementDescriptor>, val dynamic: List<DynamicFieldDescriptor>, val constraints: List<ConstraintDescriptor>)

How a query model can be queried on one entry: the answer the GET of the query route gives to agents and the view engine; QueryJson writes and reads it.

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.
