            transport: :one_shot | :control,

Canonical action outcome and original transport evidence.

A completed outcome carries the action's value; failed, skipped and unknown
outcomes carry `nil`. Match the outcome before using the value. Command
acknowledgement remains distinct from external program completion.

A completed split carries `t:LibTmux.Pane.split_value/0`. See
`LibTmux.Pane.split/3` for its identity and lifetime limits.
