plan.Plan.run

The result does not depend on the planner; the number of tmux invocations, and how precisely a failure can be attributed, do.

Errors

Returns an error when tmux cannot be reached, a process cannot be captured, a slot dependency is invalid, or a creating operation does not return valid IDs. Validation happens before the first command. A command tmux *refuses* is reported through the returned PlanResult , not as an error, because a plan may expect one.

On a handle from Server::over_control_mode, a plan holding a super::ops::Pause fails with crate::ControlModeErrorKind::BlockingCommand before anything is sent, as Self::run_over_control_mode does.

Cancel safety

The effect can be partial: steps already dispatched stay done, and the PlanResult naming them, with the ids of what they created, is lost with the future. A retry runs the whole plan again.
