Asked -seats, it reads every seat definition the heads carry, resolves the parts it includes and answers the list
with what it left out and why, so the running checker hands the manifest validator and the composer a list it does not
read itself (ADR 0636 §4, ADR 0644 §1).

mesh-checking-program -verdict reads the facts from the file the build
seat's run step names, judges them with the rules package and answers
one versioned line; facts of a version it does not read are refused,
naming it, because the running checker of B0 runs G's programs
(milestone 47/B0, ADR 0644, ADR 0656).
