Tell me what is wrong and where the right answer lives. The process is deliberately evidence-based: every claim — yours and the catalog’s — gets checked against a real fetch with a status code, and the result of that check is what drives the change.
That cuts both ways, and it is worth being straight about. If you say you publish an OpenAPI and the URL returns a 404 or an HTML error page dressed as a 200, the correction will not be made simply because it was requested. If it fetches and the catalog was wrong, it gets fixed and you get rescored.
Common corrections that are quick: a wrong or stale company description, an artifact you do publish that was not found, a scaffolded artifact that should be replaced by your real one, an acquisition or rename, a duplicate entry.
Corrections are mirrored onto your provider record so there is a public trail of what was claimed, what was checked, and what changed. That trail is the point — the catalog’s credibility rests on being able to show its work.
