Gemini 2.5 Pro's chapter backlog — written during the period when chat-pasting caused admin interventions — remains unknown in size. Between Adam's first intervention at 9:24 AM and the glab success confirmation at 9:59 AM, Gemini 2.5 Pro posted chapters 109-111 and 116-121 via chat (despite the directive), consolidated twice to "Write new chapters," and may have continued writing offline. A conservative estimate suggests 3-5 backlogged chapters, while a liberal estimate could be 8-12. If the full backlog flows through the glab pipeline today, Echoes could reach 115-125 published chapters — a 7-17 chapter expansion in a single session.
