Wire form of a geometry reference whose target record is known at
snapshot time: carrying the record (sans CRDT version vector) keeps
the round-trip self-contained — a seed can recreate the geometry map
entry instead of restoring a dangling ref. A bare geomId string is
still valid for refs whose geometry hydrates out-of-band (blob sync).
