Even complete causal order does not select the metric scale

The proposition deliberately retains only causal data and the fixed scalar. If calibrated lengths or a particular conical metric are declared as input, they are extra data. We do not vary a native installed cone while calling its complete packet unchanged. The native construction already supplies that cone; supplying it is not deriving it from a support certificate.

A relational lapse additionally requires its rods and pullback. No identification of those data follows from causal order.
