validating-claim-verify

Actively test and verify specific claims about correctness, safety, or behavior through experiments and observable evidence. Use when: (1) asked to verify a claim about code behavior, correctness, or performance, (2) statements about behavior appear without verification evidence or test results, (3) language includes modal uncertainty markers like "should work" where verification is possible, (4) discussion analyzes implementation through reading rather than execution and observation.
