Interface ColumnarBatchCacheRecordV1Experimental

One persisted cache record. Metadata only: the serialized envelope travels beside it so a backend can enumerate and evict without loading payloads.

observedAt is when this store wrote the record and drives eviction order; freshness.observedAt is when the producer observed the source and drives expiry.

    authorizationScopeDigest: `sha256:${string}`;
