fs/dataset deleted — generic File[T] wrapper didn't earn its abstraction layer gitshallow.ShallowRepo → Repo (redundant with package name) gitshallow.Repo.Register(func() error) — callbacks fire after each sync gitshallow.Repo.Init/Run — full lifecycle in one package caller (check-ip-blacklist) holds atomic.Pointer[Cohort] directly
