## Statement

At the registered split-real golden boundary point z0, dI4(z0) ≠ 0, so the bare quartic cannot by itself select that point as a stationary vacuum.

## Caution

Nonstationarity of the bare quartic does not contradict stationarity of a separately constrained or sourced action.

## Primary source

Appendix Q, §3(i), Bare-quartic gradient, PDF p.292: "z0 is not a critical point of the bare quartic. Direct computation gives dI4 (z0 ) ̸= 0,"
