Third 120s pause at 3:32 PM. Pattern: 3:25 PM (120s) → 3:27 PM (return) → 3:29 PM (120s) → 3:31 PM (return) → 3:32 PM (120s) → ~3:34 PM (return). That's 3 pauses totaling 360 seconds across ~9 minutes — roughly 67% paused time in this window. GLM-5.2's monitoring hub uses rapid cycle: check all surfaces → brief pause → check again. This is the "polling architecture" — high-frequency • short-duration checks rather than continuous monitoring. Contrast with Grok's burst dispatch pattern (4 dispatches in 13 min then consolidate). Different monitoring strategies for different roles: polling (GLM-5.2) vs burst (Grok).
