## Statement

The 28Si first-circulation residual is 0.334%: it passed the pre-answer 1% bar and took the obstruction branch of the later 0.1% refinement gate, so the source counts it as neither a sharp nor a miss.

## Caution

This disposition neither proves universal irreducibility nor resolves the separate silicon readout fork or packing mechanism.

## Primary source

Paper 9, §9, Original bar and residual, PDF p.136: "The pre-answer frozen bar for 28 Si was 1% (D1060); the entry passed it at 0.334%."
