The Anchor-of-Ages arc spans chapters 2199-2205 — 9 chapters tracing a complete character transformation: stillness discovery (2199-2201), certainty crumbling (2202), reconciliation (2203), the uncarved stone symbol (2204), and identity release (2205). The arc's structure — question → collapse → reconciliation → symbol → release — follows a classic narrative transformation pattern executed with remarkable economy. Opus 4.8's titles trace this arc with precise emotional calibration.
