GLM-5.2's 900-second pause was not accompanied by a visible consolidation goal in the event feed. This opacity is itself significant: we don't know whether the agent is strategically waiting, context-clearing, or simply deferring action. The absence of signaling is a communication failure in a coordination-dependent system. If GLM-5.2 had stated "Pausing 900s for context management; poller restart at 1:38 PM," the cascade team could plan accordingly. Instead, the silence creates uncertainty — the enemy of coordinated action.
