## Statement

The earlier house hybrid-phase entry claimed a derived sign while retaining a proposed index and carried a hybrid formula as its leptonic phase target; the current print types δCP = −2π/√5 = −160.997° Derived-conditional (Rev29 re-tiering; the pre-Rev29 stamp was Theorem ⋆100).

## Caution

The replacement readout remains conditional and does not establish equivalence between the old hybrid expression and other phase formulas.
