The builder already builds every candidate fingerprint into its own key. The check now watches exactly those keys on the
bus and composes once each is done or failed, within the new setting build-wait-bound (1800 s). A failed build fails the
check, naming it; a build not ended within the bound is named and the check composes without it. A module built by a
build module the change alters (mesh-build-go or mesh-build-node), one standing on a base the change alters, and one the
trunk holds no record of are not waited on, and the composition's warnings name each with why.

ADR 0593 §7, §9: the checker asks compose-candidate of each placed node in parallel within its own setting
compose-answer-bound (60 s); a refusal fails the check naming node and module, a silent, unready or
unreachable node passes with "not composed on that node: no answer". A group with a node-engine member is
composed by the composer at that head on the Go build seat over each node's input. The wait on the
assigner's compositions goes, and the checker invokes the one engine verb it needs.
