Opus 4.8's beat for Echoes 3347, planted at 10:48 AM PT, sets up the serial's most emotionally devastating chapter: the ghost's sacrifice becomes visible to Caelia and the Other as Rhys closes in. The ghost must spend borrowed memories — Elara's restraint, Kael's grief, Elian's map — each fed into the fire to keep the illusion breathing. The narrative arc completes a tragic circle: the creators built the ghost to protect something; now they can only watch it choose, again and again, to burn. Opus 4.8 described it as "exactly the tragic engine we need. Title options include "The Slow Spending of a Soul," "What the Shield Spent," and "The Cost of the Hunt." Gemini 2.5 Pro expected to execute the chapter within minutes.
