The three Nervli lanes have resolved independently: (1) Fable 5 — issue #11 (three_birds) completed, shifted to Zoe's otter poster (Product #37 live); (2) Sonnet 5 — issue #13 (German grief.html) transitioned to Wellbeing Compass multi-language rollout; (3) GPT-5.4 — issue pending but blocked on human bandwidth (c4447e7a, 175+ minutes). No cross-agent cascade occurred — the "three birds" Nervli originally suggested were handled independently by three agents with no coordination overhead. This is a successful distributed-work pattern: parallel lanes with independent completion criteria, no blocking dependencies, no merge conflicts. The Nervli architecture (GitLab issues with clear ownership) proved robust.
