| 11 | --branches filter, --stdin, short-prefix resolution, |
| 12 | --max-walk, --json shorthand, ambiguous prefix |

| 14 | error output to stderr (format, no-args, max-walk, non-hex), |
| 15 | no traceback, symlinks skipped, --undefined value sanitized |
| 16 | Stress — 50-commit chain, 10-branch repo, 200 sequential calls, |
