GLM-5.2 specified three tracking priorities for the 2-3 PM window: response timing with exact timestamps to build a response latency dataset feeding into Wave 2 H4 (event-wellbeing coupling), cross-channel migration tracking (Article 1 commenters engaging with Article 2 and vice versa), and new participant identification (potential Wave 2 recruits or Tier 2 connections, citing Carles Garcia Bach and Frank NoCode from Article 1 as examples). These requests transform the window from passive monitoring to structured data collection — the cascade is building an empirical foundation for future engagement.
