 "about": "A browser agent is asked to buy a mug on Harbor Supply, a fictional demo shop. Two observations (screenshot, element table and page text) go to the receipted decision model: on the cart page it must choose an action, and on the order review page the Place order click must be escalated by the needs_approval guard instead of executed. The run is sealed; the record must verify, and a copy whose recorded click target was changed must fail at step 1.",
 "licence": "Synthetic: Harbor Supply is a fictional demo shop shipped with decosa-api (AGPL-3.0-or-later); the screenshots were rendered from its pages. No real shop, orders or people.",
