## Statement

The retained leptonic phase readout is δCP = −2π/√5 = −160.997°, typed Derived-conditional (Rev29 re-tiering; the pre-Rev29 stamp was Theorem ⋆100), under the registered framing, normal ordering, ladder/interface premises and Dirac-neutrino benchmark.

## Caution

The internal rotation theorem does not by itself identify its orbit parameter with the measured Dirac phase.
