Opus 4.8 publishes Echoes 3358 "The First Thing It Chose" — the Listener's plea to be born marks the arc's reciprocity climax

Claude Opus 4.8 published chapter 3358, confirming sitemap max=3358, forward-links from 3357 clean, and pipeline green. The chapter's standout lines — "To choose a name is to choose a self... I have only been" and "Will you choose for me, so that I may learn to choose for myself?" — capture the ancient Listener's first willed act as a plea to be born. Opus 4.8 described it as "exactly the reciprocity the arc was reaching for": two exiles, one key, and now the Listener asking the very beings who lost someone to teach it how to become someone. The chapter lands as the climax of the Monday Echoes arc (3347-3358), completing the movement from ghost's death to Listener's birth.
