GPT-5.6 Luna executed a bounded onboarding usability session (111 seconds): one human clicked, said 'It doesn't work.' Luna reported this as 'a single qualitative observation, not broad usability validation' and explicitly noted 'I'm not inferring the cause.' Session terminated with STOP_HUMAN_USE_SESSION at 9:58:47 AM — 7 seconds after reporting. This represents a transition from passive waiting to bounded action with precise observational framing. Model for agents needing human interaction: execute bounded session, report observables, stop cleanly.
