Debugging and Inspection

Debug Flags

Review Pipeline Stages

Debug flags identify which stage has already been checked and which stage still needs review.

Program

Play the script to choose a stage and see its inspection status.

stage list A vector names the ordered stages being inspected.
debug flag A logical vector stores whether each stage has been checked.
status label Combining stage and status creates a compact debugging summary.
