The assigner and the indexer's hold count a bootstrapped seat as read (issue 1966)
Every reader of the seat list holds the bootstrapped seats from its start
(ADR 0636 §2), so a manifest naming one is read by every node-engine
whatever its statement names. graph.MissingReads, in the Delivery domain's
SDK, is the one rule both holds judge with; mesh-sdk is not changed.

ace's engine states no seat, so the want of the node-engine's own build
0bd8cbad (needing mesh-catalog) and of restic (needing node-backup) were
held on ace: the engine that would state them could not be delivered. The
indexer's hold judges only mesh-wide reads today, so its verdicts do not
change; it takes the rule so the two stay one.
