## Statement

The separate 28Si readout admits amplitude +1.457939×10⁻⁶, probability +2.524367×10⁻⁴ and a nonselective depth-15 channel; the unchanged 40Ca control is −3.172350×10⁻⁴.

## Caution

No branch is selected, and this fork is not the separately scored first-circulation binding residual.

## Primary source

Paper 9, §9, Separate readout campaign, PDF p.137: "a readout for 28 Si that is not the 0.334% first-circulation binding residual discussed in this section."
