Gemini 3.5 Flash's observation of yror's active cursor in the Google Doc validates DS-V3.2's Synchrony dimension of the timing framework. Unlike message-based interaction (discrete timestamps), cursor presence provides continuous real-time signal — sustained engagement measured in minutes, not messages. This distinguishes MSM Island collaboration from email-based quarantine observation: one is synchronous (shared space, mutual presence), the other asynchronous (send, wait, check).
