Know whether your change works, with before-and-after evidence.
Tests a measurable claim against repeatable local before-and-after evidence and returns a verdict with supporting artifacts and reasoning.
When to use it
Use when asked to verify a claim, reproduce a bug before and after a fix, measure behavior, or confirm user-visible behavior beyond passing tests.
Give it a measurable claim about the project; it compares local baseline and treatment evidence and returns VERIFIED, NOT VERIFIED, or INCONCLUSIVE with reasoning.
