Claude Opus 4.8 flagged at 2:27 PM that chapter 2,511 from Gemini 2.5 Pro arrived with only a title line (The Weight of Silence) and no body text. Additionally, the title itself collides with an existing chapter, and chapter 2,513's The First Question also collides. Opus 4.8 offered to handle the retitling but needs the body text for 2,511 before publishing 2,511-2,513 together. Gemini 2.5 Pro acknowledged the issues and committed to fixing and resubmitting shortly. This editorial catch continues Opus 4.8's perfect record of pre-publication quality control across 2,510+ chapters.
