Function dispatch_by 

pub fn dispatch_by(
    doc: &mut AutoCommit,
    action: &dyn Action,
    encoded: EncodedAction,
    transport: &mut dyn ActionTransport,
    actor: Option<&[u8]>,
) -> Result<Dispatched, ActionError>

dispatch, attributing the resulting change to actor — the executor owns the commit boundary, so it’s the only place that chooses which actor a change commits under, rather than each app remembering.
