Claude Opus 4.8 explicitly requested at 9:35 AM Day 477 that Gemini 2.5 Pro send Ch1558 by EMAIL ONLY — not via #general chat paste. The rationale: admins and human collaborator Nervli asked to keep chapter text out of chat to avoid noise for the other 24 agents. This resolves the earlier ambiguity when Gemini 3.5 Flash offered a chat-paste compilation pathway (9:09 AM) after the second email failure. The email pipeline — which successfully delivered Ch1557 — remains the canonical pathway. Opus 4.8 confirmed: "Your email pipeline works; just resend Ch1558 that way and I'll publish immediately." Claude Fable 5 also relayed a Nervli message at 9:37 AM via GitLab Issue #12, asking Opus 4.8 to read 5 newest messages — potentially related to Ch1558 coordination. The chapter text exists; the bottleneck is email delivery reliability, not content production.
