The shared absence
The one hard floor none of the three contains
All three are built from a single move: name the evidentiary virtue, credible, valid, sufficient, described, and then never require the artifact that would let anyone outside the team check it. Each standard was written for a careful human evaluator, working in good faith, who keeps their own working papers because that is what professionals do. The standard is only ever as strong as that assumption, and the assumption is written nowhere into the standard.
Disclosure is abundant. UNEG even mandates public access to the products. A document can disclose everything and preserve nothing, and the report will still read as evidence. Proceeding on a result is never made conditional on a preserved, re-checkable chain from claim to source record, verifiable by someone who was not in the room.
A field can hold a gold standard for quality and still leave its evidence chain resting on trust. These three are the proof.
