# Pundit's `authorize @post` and `authorize @post, :update?` are the canonical
# controller-side gate, plus CanCanCan's `authorize! :update, @article` which
# parses with the same `call` shape (method=`authorize!`). Both forms have no
# receiver — that's how we distinguish them from arbitrary `something.authorize`
# chains the rule shouldn't claim. The first argument is the resource (instance
# variable, identifier, or constant) and the optional second is the action
# symbol; we capture the trailing symbol when present.
