The mesh's own verbs are the mesh-controller seat's tools

A seat's protocol lives in the store (migration 0047; seeded additively), a served verb carries its
description and schema, holding a mesh seat requires serving its verbs, a node-scoped seat's tool
carries the node, and the control plane serves status, nodes, node, modules, seats, builds, plan,
assign, unassign, push, build and tools on its seat by running the same commands (novox/hq ADR 0132,
ADR 0154, design 33). A grant of * reaches a role's tools; seat:<seat>.<verb> grants one.
