The grants part must tell a reading of the running tool runner from an older
one, and the node-engine's composition reads the withheld subjects through a
verb of the seat, never the grants part's state.
Builds: design 46 7 §6 (the node's record takes the runner's capabilities and fingerprint; the seat mesh-grants' verb withheld, class read, callers the node-engine, persons and the operator, input node, with a fixture), lead answer A-203 (runner-capabilities, runner-fingerprint; withheld's input and answer)
