Quality terms must be backed by documents

Purity, assay, test method, and issuing lab fields should be treated as document-backed facts. They should not appear in titles, product copy, or structured data unless the related document supports them.

This is why a pending COA status is more trustworthy than an unsupported quality claim.

Separate catalog facts from document facts

A good research catalog separates product facts from quality documentation. Product pages can show name, SKU, size, price, format, stock status, and document status while the COA Library carries released document detail.

How quality facts should be published

When quality metadata becomes available, it should be entered by operators alongside the real document record and reviewed before publication.
