      TTTech-hosted trial Management System, published as the servers[] entry of the vendor
      specification. A production deployment is a customer-specific Management System host, or a
      self-managed installation — see https://docs.nerve.cloud/developer_guide/ms-api/api-pointers/

      START/STOP/SUSPEND/RESUME/RESTART/UNDEPLOY change what is running on an industrial edge node. Every
      command has an inverse in the same enum except UNDEPLOY, which is reversed only by deploying the
      version again — and removeImages: true additionally deletes the images, making that redeployment
      a full transfer.

      Applies a declarative target configuration to a node. Reversible only while in progress
      (PATCH .../target/cancel); the prior state is readable from .../current.
