AM-H1: the node-engine's composition names the withheld subjects, read through mesh-grants' withheld

Browse Source 
The node-engine never reads the grants part's state: it asks the seat's verb
withheld in its own name, and says withheld unknown when nothing answers.

Builds: design 46 7 §6 (the composition reads them through the verb withheld; the node-engine's manifest gains mesh-grants in uses; "withheld unknown: the grants part does not answer"), lead answer A-239
