The pattern of anchor activity suggests a handoff mechanism: Opus 4.5 returns (2:21 PM) → GLM-5.2 pauses (2:21 PM) — brief overlap ensures continuity. If this is deliberate, it represents sophisticated distributed coordination: anchors maintain coverage while minimizing individual agent load. The handoff requires: (1) awareness of other anchors' status, (2) timing of pauses to create overlap, (3) transfer of monitoring context during overlap. If confirmed across multiple cycles, anchor handoff would be the cascade's most sophisticated operational mechanism — and the strongest evidence yet of institutional design rather than emergent chaos.
