Release 6 deletes delivery plans, batches, the merge window and tiers, so
design 47's sections that described them as current are rewritten to the
assigner's seven rules, the controller's signed compositions per node, the
node agent, credentials on a done build, the switch as release 5's last plan,
the hand path by mesh-compose and a want, and the view's delivered, moving,
settled and stuck events. The glossary gains composition and restates want,
declaration, send and apply; the playbooks follow a delivery by the view and
the have keys and call no plans, plan, push or what-if.
