  # author ever writes `derive_from_owner!` inside a query block),

#reference_to_impl(type, as: nil, optional: false) ⇒ Object

A query parameter naming another aggregate's own identity (Card.Active's own Board, filtering to one board's cards) — just a plain attribute typed as a reference, AttributeCollector#attribute already handling an Reference exactly like any other. No "acts on itself" case to distinguish here the way a command's own reference_to has — a query has no root of its own to act on, only parameters. RENAMED FROM reference_to — item #13's full metaprogrammed dispatch (slice 4b). Bootstrap-reachable, in GenericDispatch::BOOTSTRAP_CALLS_FALLBACK.
