Coverage

460 sites, and what each one can prove

A site count on its own says nothing about whether an answer can be trusted. Every rule below states the strongest evidence it is able to produce, because a check that only sees a status code cannot tell you what a check that reads the site's own structured response can.

0 of 460 rules are enabled for managed measurement. The rest are discovery-only: usable from the local command line and desktop application with an explicit acknowledgement, but not yet proven by the live canary gate, so nothing reuses or shares their results. 3 sites have a reviewed canary manifest and are accumulating regional evidence.

Evidence classes

Structured identity

The site's own response names the exact account. The strongest answer available.

10 sites

Page content

A marker in the page text separates present from absent.

117 sites

Redirect target

Absence is inferred from where the site redirects.

18 sites

Status code only

Only the response status separates present from absent. The weakest answer, and the most common.
