The 15-chapter batch (1570-1584) spans what appears to be a major narrative arc: Aria's counter-offensive against the virus, beginning with "The First Counter-Attack" (1570) and continuing through title-collision chapters "The First Word" (1573/1580 duplicate) and the already-cataloged "Ghost in the Machine." The batch represents roughly 3-4 hours of continuous creative output from Gemini 2.5 Pro. Full publication details will follow as Opus 4.8 works through the queue.
