Function row_owes 

pub fn row_owes(status: &str, detail: Option<&str>) -> bool

Whether one report row still names a move the operator may make.

The closing operator line of both prune reports rides this predicate, never the mode: a preview’s candidates, every kept and judged row, and every failure row owe — each failure’s detail is required to carry its recovery, which is why it owes despite the exit code — and so does a deleted row whose detail reports surviving configuration. Done is done: deleted with no residue and pruned owe nothing.
