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.

AX-2026-043429
Supplier-supplied records are under 7 % of the index and they cluster on compounds where independent submissions are rare. That correlation is worth knowing before pooling them.
AX-2026-043295
Coverage on this compound is thin enough that one record moves the class median visibly. That is a statement about the index rather than about the material, and it is why the n= badge sits beside every aggregate.
AX-2026-042576
The supplier-compound cells with no endotoxin data at all are mapped on the coverage page. They are most of the matrix.
AX-2026-043486
The index would rather this page said nothing about endotoxin than said something unsupported. That is the standing editorial position and it is applied uniformly.
AX-2025-020828
The index records the absence rather than imputing a value. An unmeasured property is unmeasured, and the specification block above says so explicitly.
AX-2025-018660
The status field caps at what the panel supports. Endotoxin is one of the orthogonal measurements that would lift it, and it was not ordered.
AX-2025-019822
The status field reads PURITY ONLY, which is precisely what the record is. Nothing is being withheld and nothing is being implied.
AX-2025-019349
The rule has fired on well under one per cent of the index. That rate is the context for reading any individual instance, and it is on the rule page.
AX-2024-004359
Nothing adverse on this record. The gap is a coverage gap in the index and in the market, and it is stated rather than glossed.
AX-2024-004959
Worth flagging to whoever submits next on this lot.
