Why this test exists
A practical Stripe Link checkout readiness preflight
Agentic commerce is not a license to test a live purchase. Before a browser agent approaches checkout, teams need to know whether products are discoverable, variants and prices are understandable, the cart state is stable, authorization is explicit, and a sandbox path has a safe stopping point.
The Stripe Link Checkout Preflight projects observable public commerce signals into a sandbox-oriented contract and receipt. Its evidence includes an explicit unobservable Stripe Link row until Link is genuinely tested. It never asks for a card, clicks a final payment control, confirms an order, or asserts that Link is available merely because Stripe appears on the page.
