Resolved record set returned by list-source resolution.
RecordIds are stringified composite-key payloads in the same format used
by MJ: List Detail.RecordID. For single-column primary keys this is just
the ID; for composite keys it is the canonical Field1|Value1||Field2|…
format.
EntityName is single-valued — Lists are single-entity by design. If a
caller mixes sources of different entities, the operation surfaces an
ENTITY_MISMATCH warning rather than silently coercing.
