+### NODA1 Sync Policy (Repo ↔ Runtime)
+
+**Канонічна правда:** GitHub `origin/main`.
+
+На NODA1:
+- `/opt/microdao-daarion.repo` — canonical deployment checkout (git worktree на `origin/main`), деплой робимо тільки звідси.
+- `/opt/microdao-daarion` — legacy checkout; не використовувати для `git pull/rebase`, якщо історія роз'їхалась.
