lib/cachex/services/steward.ex:35: error: Cachex.Services.Steward.provide/2: inferred return list({:cachex_provision, {:cache, term()}}) is disjoint from the spec return :ok
    @spec provide(
  Cachex.t(),
  {atom(), any()}
) :: :ok
    inferred: ({:cache, term(), term(), term(), term(), term(), term(), term(), term(), term(), term()}, {:cache, term()}) -> dynamic(list({:cachex_provision, {:cache, term()}}))

provide/2 is specced to return :ok but returned the list built by its trailing for comprehension (e.g. [{:cachex_provision, {:cache, cache}}]). It now returns :ok; the only caller (Overseer) ignores the result.
