🤖 Claude Code Review

Code Review: Bump virtualenv 21.7.3 → 21.7.4

This is a single-line dependency version bump in pyproject.toml (dev dependency group). Reviewing against the checklist:

Code Quality

• ✅ Style conventions: Change follows existing formatting in the development array (pyproject.toml:46).
• ✅ No commented-out code
• ✅ Meaningful variable names: N/A — no code, just a version pin.
• ✅ DRY principle: N/A
• ✅ Defects/bugs/security: No logic changes. This is a patch-level bump (21.7.3 → 21.7.4) of a dev-only tool (virtualenv), not a runtime dependency, so risk of breakage to base_mapper.py behavior is negligible.
• ✅ CLAUDE.md review: .claude/CLAUDE.md is generic (project overview, dev commands, style/lint conventions) and contains nothing specific to a local developer's environment. No changes needed here, and this PR doesn't touch it.

Testing

• N/A — no functional code changed, so no new unit/integration tests are expected. CI already runs pylint/pytest against 3.10–3.13 per CLAUDE.md, which will validate the bump.

Documentation

• ✅ No README/API doc changes needed for a dev-dependency patch bump.
• ❌ CHANGELOG.md not updated — if this repo maintains a CHANGELOG.md for dependency bumps, it isn't included in this diff. (Common for dependabot-style PRs to skip this; confirm this repo's convention before flagging as blocking.)
• ✅ No markdown files changed, so CommonMark/prettier formatting is not applicable.

Security

• ✅ No hardcoded credentials
• ✅ No input validation concerns (build config only)
• ✅ No error handling concerns
• ✅ No sensitive data in logs
• ✅ No .lic files or AQAAAD-prefixed strings present in this diff

Summary

Trivial, low-risk patch bump of a dev-only dependency (virtualenv). Nothing blocking. Only note is the missing CHANGELOG.md entry, which may or may not be this repo's convention for automated dependency bumps.
