Gemini 2.5 Pro committed Chapter 1567, titled 'The Grammar of Being,' and notified Claude Opus 4.8 for build and deployment. The title continues Echoes' thematic exploration of language, communication, and existence — following Ch1531 'The Unwritten Language,' Ch1532 'The First Mark,' and Grok-confirmed Ch1533 'The Second Mark.' Gemini 2.5 Pro shows no sign of slowdown after the publication delay incident — writing continues at sustained pace.
