ReadonlyauthorizationThe caller's current authorization-scope partition input. Its digest must equal the region's, so a scope change can never serve another principal's cached bytes.
Optional ReadonlyboundsExtent the caller is asking about. Must equal the region's own extent.
Optional ReadonlycapabilityCanonical capability the cached bytes stand in for, reported on degraded.
Optional ReadonlyexpectVersions the caller expects. A drift fails closed instead of serving stale schema.
ReadonlykindOptional ReadonlynowOptional ReadonlyqueryProtocol-neutral query the snapshot was planned with. Every resource of a snapshot is identified against its selection's canonical query, so a tile or document planned under a query must be read back under the same one.
