A review reads the change. A check runs it.

Here is a two-character bug. A refund guard compares the requested amount with the captured amount. A tidy refactor drops the part that adds what was already refunded. The new line reads better than the old one. Every existing test still passes, because no test made two refunds. A reviewer, human or AI, approves it.

Nothing about that review was careless. It answered the question a review answers: does this change look right? The question that mattered was different: does the rule still hold? Can a second refund push the total past what was charged?

That question has an answer, and the answer is not an opinion. Create a payment of 100.00. Refund 50.00, which should succeed. Try to refund 50.01, which should be refused. Read the total. Either it is still 50.00 or it is not.

This is the gap Bracel is built for. Teams write code faster than ever, with more help from AI, and review it faster too. The volume of change goes up; the number of rules that must never break stays the same. Those rules deserve a check that runs them, on every pull request, before merge.

Running them is not exotic. It is what a good test does. The difference is where the rule lives and who owns it. In Bracel, the rule is a named, versioned, approved thing on your base branch. A pull request cannot rewrite the rule that judges it. The result lands on the pull request in plain terms: what was expected, what was observed, why the verdict follows, and what ran.

None of this replaces review. Review is where people decide what the code should do. A check is where the code shows what it actually does. You want both, and you want them to stop being confused with each other.
