## Statement

Can the unit-endpoint-ray readout and round-trip squaring that define the reactor-angle target be forced from first principles?

## Caution

The finite moment law does not independently derive the physical reactor-angle attachment.

## Primary source

Appendix B, Lemma B.5′, Conditional readout status, PDF p.159: "it is a theorem given the unit-endpoint-ray readout rule, but that readout rule is not itself derived from the algebra"
