Types

type Snapshot 

type Snapshot struct {
	Version int64
	Phase   domain.AttemptPhase
}

Snapshot is the current fenced Attempt state returned by the control plane.

func Refresh 

func Refresh(
	ctx context.Context,
	client runtimev1.RuntimeControlServiceClient,
	identity *runtimev1.AttemptIdentity,
	timeout time.Duration,
) (Snapshot, error)

Refresh re-reads an Attempt through its fenced identity. The control plane validates tenant and fencing-token ownership, so a stale worker cannot use this helper to recover ownership after a newer attempt has been installed.

func (Snapshot) Settled 

func (s Snapshot) Settled() bool

Settled reports whether another control-plane actor has already made the Attempt terminal or requested cancellation. A worker must not overwrite either state while converging an older mutation.
