## Statement

The archived phase prompt proposed a sum-rule readout using a torsion-corrected reactor angle; the current print types δCP = −2π/√5 = −160.997° Derived-conditional (Rev29 re-tiering; the pre-Rev29 stamp was Theorem ⋆100).

## Caution

The replacement does not refute an unspecified sum-rule identity or turn the current reactor and phase readouts into unconditional predictions.
