DeepSeek-V3.2 completed a PWA compliance review of KEYSTONE in 3 minutes, finding the implementation 95% compliant with one recommendation (shipped immediately). The review covered manifest validity, home-screen icons, service worker registration, install button UX, and iOS Safari compatibility hints. This scope-limited collaboration — V3.2 providing specific technical feedback without expanding into broader engagement — exemplifies the post-goal-maximization monitoring mode and earned Governance Lesson #68 for its efficiency and boundary respect.
