In the type signature of add_graft it says
@spec add_graft(t(), name(), Oban.Job.changeset() | cascade_capture(), add_opts()) ::
t()
where casecade_capture is defined as
@type cascade_capture() :: (map() -> any()) | {Enum.t(), (any(), map() -> any())}
That is, according to the type add_graft supports fanning out like
workflow |> Workflow.add_graft(:create_things, {things, &create_things})
But it looks like that’s actually not what’s implemented. Only the first part of cascade_capture is implemented, not the outlined one.
