INDEPENDENT CHECKS
Review this exact evidence bundle
This records a local decision. It does not approve the GitLab MR, merge code, or deploy.
Challenge the repair. Try to break it.
Enter your own values. Compare the running application with an independent browser calculation and a deliberately wrong rounding rule.
A separate calculation using the stated rounding rule.
Returned by a fresh HTTP request to this service.
Rounds half cents to even. This comparison does not run an agent.
Calculation checks use synthetic amounts only. Inspect the real Duo repair and CI evidence separately. One passing input is not proof of correctness.
Follow the incident. Inspect the proof.
Don’t trust the patch. Try to break it.
Canaries catch the silent failure, Duo proposes the fix, an adversarial verifier tries to break it, and only evidence-backed patches reach a human.
A plausible fix meets a counterexample.
Controlled local experiment. These patches are prepared by this repository, not claimed as live Duo output.
Break the checkout. See the difference.
