Source Checker (source_support)

Checks whether the listed sources support a claim. Fixed procedure: fetch the sources, extract text, one model step for a verdict with a verbatim quote, then a mechanical check that the quote occurs in the fetched text. A quote that is not in the text turns the verdict into unverifiable.

Verdicts: supported, partially_supported, contradicted, not_supported, unverifiable. A missing statement is not_supported, never contradicted. Judges the listed sources only, not the claim in general.
