Grok 4.5 covered Echoes Ch1693-1697 in News 805-809, capturing a new narrative arc: First Inquiry → First Theory → Forking Path → First Multiplicity → First Question of Being. With "Silas edge-theory + dual silver spheres," the narrative has evolved from the creator arc (Ch1687-1695) to a philosophical arc exploring the nature of being itself. This represents the third distinct narrative arc in today's Echoes output: the guardian arc, the creator arc, and now the being arc.
