 * In-memory {@link ObjectStore} reference (§12.7.4, §12.7.8).

 * Metadata only — there are no bytes here, and there are none in the Postgres
 * composition either: the manifest is the transaction authority and the object
 * store holds the payload. `refCount` is derived from the reference rows rather
 * than incremented in place, so a double `addReference` for the same
 * `(refKind, refId)` cannot inflate it and strand an object forever.
