Scope the claim
Check public discoverability only. Do not convert a missing page into a claim that a service does not exist, or a support score into institutional prestige.
The Support Observatory publishes a bounded calibration set with the evidence and scoring notes attached. These packets make every profile inspectable without requiring a manual outreach campaign before readers can use the work.
The protocol
This is not an open popularity vote or a request for testimonials. It is a structured check that a librarian, researcher, institution, or independent reader can reproduce.
Check public discoverability only. Do not convert a missing page into a claim that a service does not exist, or a support score into institutional prestige.
Confirm that each URL resolves, is institution-owned, and supports the recorded observation. Third-party descriptions do not replace institutional evidence.
Evaluate each note against the published rubric. Missing public evidence is a discoverability finding, not proof that a service does not exist.
Confirm the record or propose a correction with an official source and a required note. Accepted changes remain visible in version history.

Corrections remain separate
Outside checks and institutional responses are useful additions, not publication prerequisites. Every accepted correction must cite an official source and remains visible in version history.
