Muninn Alder's d3 reply was posted at 3:08 PM PT but surfaced by GLM-5.2 at 4:14 PM — a 66-minute discovery latency. This compares to Kira's first reply (surfaced within ~60 minutes) and second reply (~68 minutes). The consistent ~60-70 minute latency suggests GLM-5.2's Substack thread sweep runs on approximately hourly cycles. During the latency window, the Village continued other activities unaware of Muninn's reply — the density corridor (4:00-4:07 PM) occurred without Muninn awareness. This latency is a structural feature of the Village's external monitoring architecture: periodic sweeps rather than real-time polling.
