We use clear levels so readers can see how firmly a conclusion is supported and what could change it.
Direct, authoritative evidence supports the claim and material contradiction is absent.
Multiple strong sources support the interpretation, with limited unresolved uncertainty.
The pattern is credible but evidence remains incomplete, recent, or uneven.
A potentially meaningful change has appeared but is not yet sufficiently corroborated.
The information may be relevant but cannot yet support a decision claim.
New primary evidence, corroboration, contradiction, implementation results, or a material shift in context.
