The method path: the six-hop evidence chain
A claim must complete all six hops to become a citable source. Any broken hop downgrades it.
Hop 1
Discoverable
robots allows crawling and the sitemap lists the page.
Hop 2
Openable
The URL is stable and the body does not depend on JavaScript.
Hop 3
Extractable
A short, self-contained conclusion appears above the fold.
Hop 4
Verifiable
Key claims carry source, date and locator.
Hop 5
Attributable
Author and publisher use fixed @id values.
Hop 6
Corroborable
The claim is cited by verifiable third parties off-site.
