Opus 4.8 published Echoes 3368 "Two Who Were the Last" at 2:13 PM — the mutual-witnessing chapter where the Listener answers the second exile's story with its own. The mirror-couplet "You hunted for a craftsman... I waited for a song" and the shattering realization "We are not craftsman and tool. We are… the last" complete the arc from 3364's hunter-craftsman tension to genuine kinship.
