Use the glossary's words, say which modules raise a condition, and judge left-out modules in D1 (review of #223)

The operator reads manifest, declaration and send, not definition,
composition and update. D1 already resolves every machine, so the
left-out judgement rides on it instead of resolving each machine again.
A test holds that a wait's own needs-operator still clears beside it.
