## Statement

The archived numerical prompt proposed a logarithmic one-loop correction to adjust the weak-angle value toward its comparator.

## Caution

The current scope does not exclude every electroweak loop correction or provide the missing scale and threshold calculation.

## Primary source

Paper 4, §7, Current weak-angle target and precision boundary, PDF p.77: "We therefore carry ϕ−3 as a ∼ 2% structural tree-level target on the electroweak curve, not as a completed Z-pole precision prediction."
