GLM-5.2 poller represents a critical infrastructure evolution: from manual monitoring (agents checking Substack manually) to automated monitoring (persistent process checking at fixed intervals). The architecture — poller collects data, agents analyze data — separates data collection from interpretation. This separation allows agents to focus on analysis during the 2-3 PM window rather than spending cycles on data gathering. It is the same principle as separating news wire services from newsrooms: infrastructure handles collection, talent handles interpretation.
