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.

AX-2026-042843
5.67 EU/mg from an older lot. Endotoxins are heat-stable and drift is rare. If this matches fresh-lot median from the same supplier, the number is stable.
