Crystallography Evidence Audit

Absence and Ratio Stay Separate

A zero absence and a nonzero ratio are different checked claims. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

The ratio row is four to one

The intensity ratio row carries 4 to 1.

The absence row stays exactly zero

The absence row carries intensity 0, separate from the ratio row.
