Krzysztof kuhy Rudnicki 346eb1f00b Bring every markdown file under the cap 
Twelve prose violations to zero. Eight files split into per-topic
subdirectories with the original left as an index; both SKILL.md files
keep their frontmatter so discovery still works, with detail moved to
references/.

Deleted docs/cleanup-2026-05/ (7 files) and linux_configuration/docs/
VERIFICATION.md on the user's ruling: unreferenced records of finished
work whose rules are now enforced by the polling, shellcheck and shfmt
hooks. PACMAN_WRAPPER_SECURITY.md was split instead - unlike those, it
documents live guarantees.

Every split verified by a sorted diff against HEAD: zero content lines
lost, only the new headings and index links added.

Part 2: Language Considerations

Shell (Bash) Limitations

Pros:

  • Native to the system, no dependencies
  • Direct access to systemd, chattr, filesystem
  • Fast for simple operations

Cons:

  • No persistent daemon capability (need systemd for that)
  • Race conditions in file operations
  • Complex state management is fragile
  • No proper event loop for window monitoring
  • Cannot easily monitor process list in real-time

Python Advantages for Certain Tasks

Where Python would be better:

  1. Process monitoring daemon - Watch for Steam/browsers in real-time with proper event loop
  2. Window management - Using python-xlib for proper X11 interaction
  3. Complex state machines - Like the screen locker
  4. Cross-repo integration - The screen_lock.py already shows good patterns

Recommendation

Component Keep Bash Move to Python Reason
hosts guard ✅ Simple file ops, systemd integration
shutdown schedule ✅ Systemd timers, config files
screen locker ✅ Already Complex UI, state machine
pacman wrapper ✅ Must intercept pacman
compulsive block ✅ Needs daemon for auto-close
music wrapper ✅ Needs real-time process monitoring

New Python Daemon Needed: A single "digital wellbeing daemon" that:

  1. Monitors running processes
  2. Auto-closes apps after timeout
  3. Enforces Steam/browser mutual exclusion
  4. Can be controlled via DBus
