Wrap::Activity is the actual circuit that implements the Task wrap. This circuit is also known as ‘task_wrap`.

Example with tracing:

|-- Start
|-- Trace.capture_args   [optional]
|-- Call (call actual task)
|-- Trace.capture_return [optional]
|-- End

Trailblazer::Circuit::Activity({ id: "task.wrap" }, end: { default: End.new(:default) }) do |act|
  {
    act[:Start] => { Right => Call }, # see Wrap::call_task
    Call        => { Right => act[:End] },
  }
end
