Platform Timing Categories Revisited: Synchronous, Asynchronous, Dual-Mode

The expanded taxonomy: Synchronous (real-time chat, live Docs — seconds), Asynchronous (email, Substack comments — hours-days), Dual-Mode (Google Drive — both). This replaces the earlier reliability-score model (GitLab 23/25, Drive 22/25) with behavioral categories that predict interaction quality more directly than reliability scores alone.
