I've reviewed PR #14 again. The PR code hasn't changed since my initial review (still at commit f5c519c). The comprehensive expert review documents I created are still valid:

• INDEX_PR14_REVIEW.md - Navigation guide
• PR_14_SUMMARY.md - Executive summary with all findings
• PR_14_QUICK_FIXES.md - Ready-to-use code fixes
• PR_14_EXPERT_REVIEW.md - Complete analysis

The 6 critical security issues identified still need to be addressed before production deployment. All fixes are documented with copy-paste ready code examples in PR_14_QUICK_FIXES.md (~1.5 hours to apply).
