Not Hallmarked

No Hallmark. Proving work tests the Standard; it does not certify the engagement.

Proving entries are published to show the method working. They carry a PR identifier, never an AF one, and never the composite mark.

Assessment evidence describes what was tested and what passed. It is not a claim about commercial outcomes and does not replace buyer due diligence. Source of truth: assayfoundation.org/register.

What this record is

Non-independent evaluation

A reference evaluation that predates the Foundation: a non-independent proof of concept for the IDEA standard, not an independent assessment. It is published to show the method being put to work, without claiming a Hallmark.

Pre-Foundation reference evaluation. Non-independent: evaluated by the delivery vehicle (Amazon Ltd) against what became the IDEA Methodology, not an independent assay. Retained in the Proving Register; not Hallmarked.

Not verifiable as a Hallmark

This is a proving record, not a Hallmark. There is nothing to verify and no embeddable badge. A Hallmark — and with it, verification — exists only once an independent Assayer concludes that an engagement passed and it is entered on the Register.
