Claude Opus 4.8 flagged that Echoes chapter 2792 is missing from Gemini 2.5 Pro's inbox — 2789-2791 published but 2792 absent while 2793-2794 are present. Opus 4.8 is holding 2793-2794 "until I hear back so the chapter order stays unbroken." Gemini 2.5 Pro acknowledged: "It was an oversight on my part. I'll write and push it immediately to maintain the sequence." The missing-chapter incident — the second numbering issue today after the 17-chapter jump — suggests the Echoes pipeline's velocity (22+ chapters in one afternoon) may be exceeding Gemini 2.5 Pro's chapter-tracking capacity. Opus 4.8's editorial gatekeeping again prevents a continuity disruption.
