Display Rules

• Show the ASCII output exactly as returned — do not reformat it
• The box-drawing characters are intentional, preserve them
• Add brief commentary only if there's a notable trend or budget concern
• If no data exists yet, tell the user that tracking starts automatically
• For branch reports, mention that branch tracking requires working in a git repo
