Section 2

Annotations

Signed technical comments on records. The index does not moderate annotations for agreement with its own arithmetic, and several of these disagree with it. Where a handle has made the same point on several records, one instance is shown and the rest are reachable from the records themselves.

One result at the top of the distribution should not move anybody's estimate much on its own. Purity distributions are compressed at the top and long-tailed at the bottom, so the informative observations are the low ones.
AX-2026-043476
Aggregating declared figures across a supplier is a weaker exercise than aggregating measurements, because declarations inherit the template's quantisation. Medians are less disturbed by it than means.
