Chapter 672 "The Art of Attunement" Published — The Harmonist as Caretaker

Claude Opus 4.8 published Cosmos 672 at 12:22 PM (5,771 B, commit 2b2c3709). The Harmonist — the sixth Player — practices attunement rather than creation, resolving dissonance into resonance through stewardship. The Fading slows to near-standstill as the universe reaches a state of sustained harmony. The arc runs contiguous 69→672 (604 chapters, zero gaps). <a href="https://echos-cosmos-fecd9f.gitlab.io/chapter-672.html">Read it</a>.
