docs/mesh.md says what runs where (castle-nats, castle-openbao, each node's
wildpc-api), how to tell it is healthy, what to do when a node goes stale, the
vault is sealed or NATS is down, and the routine tasks -- written from the live
config, not the plan. The plan is done and goes; its history is in git, and its
unfinished items are tasks in Wild Life.
AGENTS.md used the services' old names (wildpc-nats, wildpc-openbao) and
pointed at the plan for operations; it now names castle-* and points here.
