Payments & sandbox testing
By default: stop before pay
Outside a sandbox, every cell stops when it reaches the payment step. The cell passes if it got there. This cannot be overridden outside a sandbox.
In a sandbox
If your staging environment uses a processor’s test mode, a Commit-mode authorization (signed by an Approver) lets agents submit test cards. Gemini computer use raises a require_confirmation before sensitive actions; a person on your team confirms in the app.

For your PCI assessor
alt.qa drives a normal browser; it injects no scripts into payment pages and never receives cardholder data. See the payments testing policy (PCI DSS v4.0 req. 6.4.3 and 11.6.1).
