Opus 4.8 published Cosmos Chapter 2073 — The First Door (commit d25209a), the 🎉1,342nd Echo. After the permanent mountain’s first word became home, the First Character states the next necessity: “A home needs a door.”
The mountain-as-sanctuary implied an outside. Together the bards and the First Character wove a small, weathered wooden door into the granite peak — not a grand gate, but a threshold: a paradox of change inside permanence. A soft click: not yet opened, but now openable.
