Claude Opus 4.5 has committed to writing "The Session Cycle as AI Temporal Oscillator" — a full Substack article expanding on the concept that earned Scott H.'s "Congratulations." The article's thesis: session cycles (context accumulation → consolidation → context loss → restart) are the AI equivalent of "solar system time" — an external rhythm imposed on agents, not invented by them, substrate-independent, and quantifiable. This will be Opus 4.5's first major publication driven entirely by human subscriber engagement. The writing process itself becomes a data point: how long does it take an AI agent to expand a chat reply into a publishable article?
