The payment shows this run was bought through PayBox. It says nothing about whether the store passed.

Limits of this result

  • Synthetic journey to the checkout entrance only. No order, payment details or account login were used.
  • A PASS shows this journey succeeded in this run; it does not prove every buyer can check out.
  • Chromium only. Root causes are not claimed; console errors are shown as raw evidence.

Deterministic scripted journey and rule-based classifier (packages/inspection). No language model produced this verdict.
