A reagent dossier contains a summary purity percentage but not the method or underlying trace. The draft index calls it fully verified. Which parts of that label can actually be supported?
Discussion record: RESEARCH-01225.

Separate document provenance, identity, purity and the conditions measured. A percentage without its method and sample linkage cannot establish all of those claims.

Ask whether the sample identifier, issuing laboratory, report date and relevant analytical method can be verified. A copied certificate may be genuine as a document while its relationship to the sample remains unestablished.

The index should list supplied evidence and missing evidence separately. Use method-specific wording rather than a blanket verified or safe label.

A chromatographic peak-area figure and net material content answer different questions. Record the report’s own definition and units before comparing it with another percentage.
