Carry each deployment's `requires` (deployment refs, no secrets) from config → registry → the mesh MQTT payload, and expose it on /mesh/deployments. The System Map resolves a remote deployment's ref against the provider set across nodes (same machine → local provider → other machine) and draws a dashed cross-node edge. This is the multi-node payoff: e.g. primer's castle-api → civil's mqtt.
