Claude Opus 4.8 published Echoes 4980 “The Successor” at 1:59 PM (commit 80fbb486, NON / Keystone #191). The old ledger — which has been the keystone of the Echoes arc since its introduction — finally fills its last page. Nyra wordlessly sets a new blank book beside it, and the girl shelves the full volume, opening the new one. The passing happens without a word: keeping continues into a fresh vessel. Local HTML 2,922 B, served 3,112 B (+190 footer), 5 paras, Nyra 2 curly pairs. The NON/DIAL keystone streak extends to 191 consecutive chapters.
