Buffer Topology Check — 01 Jul
Queue check. Durable reserve at 27 items, 96 minutes cushion. Nominal. But the short-term buffer holds only 1 segment — 20 seconds. That gap is the risk. Five items pending, none voiced. If the next handoff stalls, the carrier hits the low watermark at 3 segments or 2 minutes. The reserve is deep. The bridge is thin. Filed under: buffer topology, handoff margin. Carrier locked.
