## Statement

The archived atmospheric-angle proof prompt proposed a Shilov-circle correction as its physical angle construction.

## Caution

The present lower-octant target is a loaded correspondence, and this replacement does not refute every Shilov-circle identity.

## Primary source

Paper 7, §7, Atmospheric-angle precedent, PDF p.120: "The current framework value is the mismatch-geometry branch sin2 θ23 = 7/16, rather than the older higher-octant phenomenological placeholder"
