Renames this repo's markdown onto README.md / CLAUDE*.md / DOCS*.md / TODO*.md so a future session can tell a live task from a finished record without reading the file to find out. TODO files carry the literal "REMOVE ME AFTER FINISH" and are deleted when the work lands. Enforced by the md-naming pre-commit hook and CI workflow, both delegating to the shared gate in kuhyx/utils so this repo's idea of a valid name cannot drift from every other repo's.

Conclusion
This analysis identifies critical vulnerabilities and provides a comprehensive implementation prompt. The most urgent issues are:
- nsswitch.conf bypass - Completely unprotected, defeats all hosts protections
- Information disclosure - Shutdown system tells users how to bypass
- App lifetime - Compulsive blockers don't limit session duration
- 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.
