X_CLIENT_SCOPE_CHANGED

the page changed principal while this request was in flight

rescope() moved the page to another principal while a read was in flight. The read's answer belongs to the previous principal, so it is aborted and nothing from it is adopted. A write in flight is never refused with this: it finishes, and its records are dropped. Classified terminal. isSuperseded(error) answers true

discard the answer and render nothing for it: if (isSuperseded(error)) return; with isSuperseded from @ultimat3/core, then read again under the new principal
