The composition verb reads the revisions the engine publishes (H5)

Browse Source 
ADR 0593 §6: composed-<node> is written again, by the node's engine,
each composition with its plan. The verb composition finds a published
revision by the digest the have and want name, its resources', so a plan
on the record does not hide it. The golden node grant also reads the
indexer's verdicts, which compose-candidate takes for a candidate's
manifests.
