Cross-validation audit by Codex + Opus identified 14 issues: CRITICAL: - Fix _find_subdir_ci() prefix match accepting wrong folders (e.g. Publish_old). Now uses exact case-insensitive match. HIGH: - Add pack-sequence CLI subcommand with unambiguous arg parsing. Deprecate --sequence on pack (nargs='+' consumed the target). - Fix Windows UNC/drive path normalization in bpathlib.make_absolute() - Fix ZIP failure losing traceback + progress bar stuck on error - Fix os.path.commonpath crash on cross-drive paths (new derive_common_project helper) - Fix progress bar saturating at 40% during trace (log scale) MEDIUM: - Add per-shot error isolation in sequence scan (collect all errors) - Add memory warning for >50 files in sequence pack - Improve pack-info.txt with dedup stats - Wrap single Path in list for old operators (type consistency) LOW/INFO: - Document VERSION_RE pattern - Add TASK_CHOICE_ITEMS empty guard 28 new tests in tests/test_sequence_pack.py, 0 regressions.
