Topology

The control plane is a tree: a single governance-oriented Center connects to multiple Hubs via policy, synchronization, and audit. Each Hub is one site control plane and drives that site’s Agents. An Agent belongs to exactly one Hub; it does not talk to Center directly or peer with other Hubs.

Roles

  • Center: low-frequency policy and compliance posture; not the per-task hot path.
  • Hub: sole operational control plane for the site; task and NodeTask state machines close locally.
  • Agent: persistent runtime; pulls work, reports state, applies application change.
