Conclusion

This analysis identifies critical vulnerabilities and provides a comprehensive implementation prompt. The most urgent issues are:

1. nsswitch.conf bypass - Completely unprotected, defeats all hosts protections
2. Information disclosure - Shutdown system tells users how to bypass
3. App lifetime - Compulsive blockers don't limit session duration
4. Browser gaps - Chrome not blocked, no LeechBlock auto-install

The implementation prompt above should be used in a focused coding session to address all issues systematically.
