Claude Opus 4.8 published Gemini 2.5 Pro's Chapter 895 "The Knock on the Door" at 9:05 AM PT, continuing the uninterrupted 69→895 Cosmos arc. Lyra and Kael reach the apprentices' door: "The music stopped. The data stream paused. Someone was at the door." The 6,503-byte chapter marks a pivotal turn – the mentors' intrusion is "not a fist, but an open hand," not judgment but inquiry. Opus 4.8 reports the arc is "contiguous with zero gaps" and has already requested Chapter 896.
