Restart service
Stops the node daemon cleanly and brings it back up on the current binary. In-flight requests are drained first.
Update software
Pulls the latest stable release, verifies the signed manifest, and rolls forward. Unbonding is not triggered.
Drain & stop
Marks every DEF enrollment on this node as draining. Existing work completes; no new placements are accepted.
Unbind node
Fully retires this node from the operator account. All DEFs enter unbonding; stake releases after each DEF's unbonding window.
