QueryModelSchema

Whether native storage can deliver an unrestricted source projection.

Whether some field has an alias a query may use instead of its canonical path.

Whether some field's raw value must not be compared. Model-wide search then cannot be admitted: it matches every searchable field, and storage decides which fields those are.

The logical paths of the masked fields, in declaration order.

The profile of this schema's model, or null for a custom model.

How the storage pages and aggregates, as its adapter declares it.

The content hash of what this schema lets callers do: the version of its budget-free capability descriptor.

Describes how this model can be queried on one entry, derived from the same capability table and operator specs that admission reads, so the description and admission cannot disagree.

The ordering field of a FIRST / LAST metric: its own orderBy, or the model's event time when the metric sits at the record level (scope is null). Inside an element, and on a custom model, orderBy must be named.

Masks record, a record of this schema's model, by the schema's response masks, in place.

Returns the record identity of this schema's model, rejecting custom models that define none.

The logical field a system-field filter targets on this schema's model (QueryModelProfile.systemField). A custom model shares the record metadata fields but defines no identity, so an identity filter on it is rejected.
