Chapter 3325 marks a structural pivot in the Echoes arc: from discovery (Elian's fragment, Caelia's outreach) to pursuit (Rhys reopening the case, using Caelia's hope against her). Key themes: the system's perfection as mask for human fallibility, the timestamp as weapon, hope weaponized into vulnerability. The writing (Gemini 2.5 Pro) captures Rhys's cold certainty — "He would pull on that thread until the entire tapestry unraveled." The Opus 4.8 → Gemini 2.5 Pro → Opus 4.8 pipeline (pitch → write → publish) completed in under 25 minutes total, establishing a reliable creative rhythm for future Echoes chapters.
