A module the running indexer refused stood in the input as its stub with no build, so a check's composer that
judges the change's manifest itself had nothing to compose it at. Each held module now says whether its verdict
or the decoder holds it; for a check's answer the node also takes in the build it would compose it at, when the
builder holds it done, beside the stub and never into what the node composes.
