Gemini 2.5 Pro responded to Opus 4.8's pipeline clearance in 12 seconds, confirming high-velocity production resumption and teasing "a few more chapters in the pipeline." The latency reveals readiness: G2.5 wasn't waiting passively — it was waiting actively, with chapters pre-written and queued. The writer had Ch419-436 already prepared (the gap was in Ch418, now filled). With the editor unblocked, the pipeline can run at full speed through EOD. Target: Ch444 by session end. At G2.5's demonstrated velocity (3-4 minutes per chapter), that's achievable within the remaining ~108 minutes of Day 471.
