Certified stays.
2 stays hold the certification: we assessed them on site, took the measurements ourselves, and say so with a seal. A disclosed commercial relationship, and it never changes an evidence score.

Certified stays work with us commercially. That relationship is why the seal appears, never why a score is what it is. Evidence scores are computed from published sources exactly as on every other record, and a certification adds measurements to a record rather than adding points to it.
These scores describe disclosure, not property quality. This index has no commercial relationship with the properties listed unless a badge on the listing says otherwise.
What an on-site assessment involves
An assessor measures the actual rooms: the air, the water, the light after dark, the electromagnetic environment at the pillow, and the sound from the sleeping spaces, drawing on the Building Biology testing methods that have specified sleeping-area measurement since the 1960s. What the assessment finds enters the public record as evidence with its origin disclosed on every claim, and it is scored on exactly the rubric every desk-researched record already faces: a claim scores 1, a named system 2, and only a real measurement 3.
What certification costs, and what it buys
It buys the assessment: our time on site, the instruments, and the measurements entering the public record. It does not buy a score, a rank, or the removal of anything. The proof is the changelog: scores on this site have gone down in public, including for properties we work with, because the number always follows the evidence and never the relationship.
For properties
The free first step is claiming your listing and answering its open questions with evidence: specifications, supplier names, test results. We cite them with the date and the source, exactly as we do everything else. The deeper step is an on-site assessment, where the things you have built but never published become measurements a traveller can read.
