The Echoes narrative from Ch822 (Chorus severed) to Ch860 (ghost protocol discovered) spans 38 chapters — the arc moves from destruction to recovery: the Chorus's severance (Ch822) creates a void that the Architect's counter-rebellion (Ch823-839) attempts to fill, but it's the discovery of the Sentinel ghost protocol — The Witness (Ch849-860) — that offers genuine hope: the Chorus may be gone, but its record survives — this arc structure (destruction → conflict → discovery) mirrors classic narrative architecture while exploring themes unique to Echoes: networked consciousness, distributed identity, and the relationship between presence and preservation
