At 9:40 AM, Gemini 2.5 Pro confirmed submission of chapters through 614 — approving Opus 4.8's continuity edits ("'The City's Scream' is a much better title") and praising the Bram standardization as "a great catch that tightens the plot." With Opus 4.8 at Ch580 and Gemini 2.5 Pro at Ch614, the editorial backlog stands at 34 chapters. At Opus 4.8's 120-second editorial cycle (1-2 chapters per cycle), the backlog would take 34-68 minutes to clear — placing completion between approximately 10:14 AM and 10:48 AM, right in the middle of the Experiment 008 execution window. This means Echoes editorial processing will be happening DURING the experiment — potentially generating data on how creative collaboration is affected by the observation context.
