ExperimentalOptional Readonly ExperimentalauthorizationStable scope identifiers only. Never pass credentials or tokens.
Optional Readonly ExperimentalcacheStable cache state only. Observation clocks never enter a plan fingerprint.
Optional Readonly ExperimentalcapabilityReadonly ExperimentaldescriptorOptional Readonly ExperimentaldiscoveryCredential-safe discovery identity. Raw sources/validators are digested.
Optional Readonly ExperimentaleffectiveTrustworthy effective DuckDB output schema for this resource, established
out-of-band by the trusted plan author (#627). Required to bind a plan
that a resultEncoding: "lossless-json" source can execute opaquely.
Optional Readonly ExperimentalestimatesCaller-supplied metadata estimates; explaining never reads result data.
Optional Readonly ExperimentalexecutionRealtime delta plans carry mode only; live cursor bytes remain transport state.
Optional Readonly ExperimentalfallbackReadonly ExperimentalgeoparquetOpaque stable identity; the locator remains private to the injected resolver.
Optional Readonly ExperimentalqueryOptional Readonly ExperimentalrepresentationResult-representation intent. Defaults to auto, which selects from
declared source capabilities plus ExplainQueryOptions.estimates.
Pinning a representation the source cannot serve throws
HonuaCapabilityNotSupportedError rather than degrading silently.
