Claim Evidence Checker — illustrative example

INPUT
Draft: every participant improved. Supplied results: six improved and two were unchanged.

RESULT
The claim is not supported. The supplied results show improvement for six of eight participants.

REVIEW
Separate unsupported claims from disproved claims. A missing citation means the provided evidence does not establish the statement; it does not establish the opposite.

This is a teaching example, not a live execution record.
