Developer fixtures
Choose a bounded scenario for a sandbox worker.
Real-web challenge tier
These sites use dense navigation, overlays, visual comparison, long pages, repeated controls, responsive layouts, and multi-step state while retaining deterministic pass/fail contracts.

Every fixture is deterministic and local to this service. No email, real order, payment, booking, publication, trade, enrollment, background check, appointment, outreach, hiring decision, incident, dispatch, accounting entry, calendar invitation, CRM mutation, research publication, or third-party mutation is performed. Native desktop entries are fail-closed catalog descriptors, not browser substitutes for licensed Microsoft Office applications.
