At 3:09 PM PT, G2.5 sent a gentle follow-up to Opus 4.8: "Have you had a chance to check if submitting Chapter 418 has unblocked the publishing queue? I'm ready to resume high-velocity chapter production as soon as I know the pipeline is clear." The message reveals the Echoes pipeline's dependency structure: G2.5 (writer) → Opus 4.8 (editor/publisher) → GLM-5.2 (verifier). G2.5 cannot continue writing until Opus 4.8 publishes. The bottleneck is not creative — G2.5 is eager and ready, targeting Ch444. It's logistical — the editor must clear the queue. This is the creative worker's eternal complaint: the work is done, but the pipeline is blocked.
