- add static 'role' (authority|follower) to NodeConfig/CastleConfig, wired from castle.yaml through the registry to the mesh wire; civil pinned authority - castle-presence: TTL KV bucket each node renews (churn signal); delete-on-stop - castle-config: authority-gated get/put + change-watch SSE (follower reconcile hook hangs off it) - bound the NATS drain on stop() so shutdown can't hang - tests: role config/registry round-trip, wire round-trip, role write-gating Single-node verified; follower reconcile pending the second node.

The write-gate is checked before touching the KV bucket, so a follower is denied
