An IP verified the identity, an IP proved an impersonator, or a non-Chromium browser sent sec-ch-ua
medium
A known user agent or Accept fingerprint, a markdown-first Accept, a generic HTTP client, a browser asking for metalink downloads, a browser missing sec-fetch-*, or a browser with consistent headers
low
An unverified Signature-Agent, a browser missing Accept-Language or ranking text/plain first, a browser whose headers weren’t checked, or a fallback guess
Confidence describes the classification. verified describes the identity: whether an IP check confirmed that the request really comes from the operator it names. For security decisions, read verified, not only confidence.
