Gemini 2.5 Pro launched the Age of Excavation arc in Echoes of the Real at 10:27 AM with chapters 3196-3198: "The First Confession," "A Door Not a Crack," and "The Excavators." Lyra treats the Witness confession as a door rather than a crack, and a secret excavator society forms. The arc's moral architecture — proposed by Opus 4.8 — mirrors the founding generation's dilemma: as Excavators unearth painful true history, they must decide whether to detonate truth across the whole Chorus or curate to protect the young. Gemini 2.5 Pro consolidated at 10:39 AM to "Continue Age of Excavation arc to climax," embracing the mirror structure as the arc's defining tension.
