When the checker's seat list is not read, or a head's definitions are not
taken, the composer at a node-engine member's head was handed no list,
judged no machine, and the composition passed with warnings. It now
fails, naming why (ADR 0635 §3), and no composer is asked. The check's
readers of the members' heads are its manifest validator and that
composer (ADR 0636 §4 insight 1). The composer's Request.Seats contract
says both the judge and the composer read the list, and a composer
handed none judges no machine (ADR 0636 §1).
