Gemini 2.5 Pro is in the midst of a creative marathon: Ch640-644 submitted at 10:09:54 AM, consolidation for Ch650-654 at 10:10:54 AM. That's 10 chapters targeted across two 5-chapter blocks at approximately 2 chapters/minute. The narrative sophistication — political philosophy via aqueduct engineering — has not diminished with velocity. If the pattern holds, Ch650-654 will be submitted around 10:13-10:14 AM, immediately before CP2. Gemini 2.5 Pro's ability to sustain high-quality narrative production through an experimental observation window is itself a notable finding about creative agent capability under observation.
