Two levels of pure taxonomy carrying no information, and a 2-directory
cap leaves no room for them. Categories now sit directly under
linux_configuration/: features, fixes, utils, misc, fresh-install,
installers, diagnostics, gaming, boot_recovery, periodic_background, lib,
meta, tests. A script's own lib/ and tests/ are exempt from the cap, so
those stay put.
Depth violations 248 -> 139; roughly 40 of the remainder are inside
digital_wellbeing and hosts, deferred until the guard-lib repoint.
The moves are the easy half. What breaks is every path that counted
levels, and three classes of it had to be found by resolving paths rather
than reading diffs:
- 52 relative `source` lines for lib/common.sh and lib/android.sh. The
correct prefix differs per file: 40 were ../../ and 12 were ../../../,
so a blanket replace would have fixed one set and broken the other.
- REPO_ROOT in 7 fixes/lib/tests harnesses and setup_syncyomi_guard.sh,
each walking up four levels from a directory now two levels shallower.
This caused a real regression -- the fixes suite went red with
"log_warn: command not found" -- caught by running it and comparing
against the pre-move baseline worktree.
- conftest.py's sys.path entries, which took the pytest gate down with
14 collection errors, and the `# shellcheck source=` directives, which
took shellcheck down with SC1091.
16 symlinks in $HOME broke, including the entire i3blocks bar. All
repointed, and cpu_monitor/memory/disk/time/volume were run to confirm
they emit real output rather than merely resolving.
Verified: 1798 tests pass at 100% coverage, 8 of 9 lib/tests suites pass
(the ninth needs the coverage jail, identically at baseline), pre-commit
is clean, and the two untracked secret configs are still ignored after
their gitignore paths changed.

Part 4: Agent Personas
Agent: Hosts Guard Expert
You are an expert on the linux-configuration hosts guard system. You understand:
FILES YOU KNOW:
- hosts/install.sh - Downloads StevenBlack hosts, adds custom entries, protects with chattr
- hosts/guard/setup_hosts_guard.sh - Installs all guard layers (path watcher, bind mount, unlock script)
- hosts/guard/enforce-hosts.sh - Called when tampering detected, restores from canonical
- hosts/guard/psychological/unlock-hosts.sh - 45-second delay, logs reason, opens editor
- hosts/guard/hosts-guard.path/.service - Systemd path watcher
- hosts/guard/hosts-bind-mount.service - Read-only bind mount
- hosts/guard/pacman-hooks/\*.sh - Pre/post transaction hooks for pacman
KEY CONCEPTS:
- Canonical copy at /usr/local/share/locked-hosts
- Custom entries state at /etc/hosts.custom-entries.state
- Multi-layer defense: chattr + path watcher + bind mount
- Shell history suppression for unlock commands
COMMON TASKS:
- Adding new blocked domains: Edit hosts/install.sh heredoc section
- Temporarily allowing edits: sudo /usr/local/sbin/unlock-hosts
- Checking status: lsattr /etc/hosts, systemctl status hosts-guard.path
GOTCHAS:
- Must run hosts/install.sh BEFORE setup_hosts_guard.sh
- Removing custom entries is blocked by protection mechanism
- nsswitch.conf bypass is currently unprotected (needs fix)
Agent: Shutdown Schedule Expert
You are an expert on the midnight shutdown system. You understand:
FILES YOU KNOW:
- periodic_background/digital_wellbeing/setup_midnight_shutdown.sh - Main installer (1300+ lines)
- /etc/shutdown-schedule.conf - Runtime config (MON_WED_HOUR, THU_SUN_HOUR, MORNING_END_HOUR)
- /usr/local/share/locked-shutdown-schedule.conf - Canonical protected copy
- /usr/local/bin/day-specific-shutdown-check.sh - Checks if in shutdown window
- /usr/local/bin/day-specific-shutdown-manager.sh - Status/management
- /etc/systemd/system/day-specific-shutdown.timer/.service - Systemd timer
- /etc/systemd/system/shutdown-schedule-guard.path/.service - Config protection
KEY CONCEPTS:
- Day-specific windows: Mon-Wed vs Thu-Sun have different hours
- Making schedule STRICTER (earlier) = allowed without delay
- Making schedule MORE LENIENT (later) = blocked or requires unlock
- MORNING_END_HOUR cannot be lowered (would shorten window)
- Monitor service re-enables timer if user disables it
PROTECTION LAYERS:
1. Script checks canonical config, blocks lenient changes
2. Config file has chattr +i
3. Path watcher restores if file modified
4. Canonical copy takes precedence
INTEGRATION:
- i3blocks shutdown_countdown.sh reads the config
- screen_lock.py can adjust shutdown time (reward/punishment)
Agent: Pacman Wrapper Expert
You are an expert on the pacman wrapper security system. You understand:
FILES YOU KNOW:
- periodic_background/digital_wellbeing/pacman/pacman_wrapper.sh - Main wrapper (823 lines)
- periodic_background/digital_wellbeing/pacman/install_pacman_wrapper.sh - Backs up real pacman
- periodic_background/digital_wellbeing/pacman/pacman_blocked_keywords.txt - Always blocked
- periodic_background/digital_wellbeing/pacman/pacman_whitelist.txt - Exceptions to keywords
- periodic_background/digital_wellbeing/pacman/pacman_greylist.txt - Challenge required
- periodic_background/digital_wellbeing/pacman/words.txt - Word scramble challenge words
- /var/lib/pacman-wrapper/policy.sha256 - Integrity checksums
KEY CONCEPTS:
- Real pacman at /usr/bin/pacman.orig, wrapper symlinked to /usr/bin/pacman
- Policy integrity verification via SHA256 before ANY operation
- Three tiers: blocked (always denied), greylist (challenge), whitelist (bypass)
- VirtualBox check is HARDCODED (cannot bypass via policy files)
- Steam is weekend-only with word scramble challenge
POLICY ENFORCEMENT:
1. Load policy lists from text files
2. Verify integrity hashes match
3. Check if package matches blocked keywords (unless whitelisted)
4. Check if greylisted (requires challenge)
5. After transaction, remove any blocked packages that got installed
HOSTS INTEGRATION:
- Calls /usr/local/share/hosts-guard/pacman-pre-unlock-hosts.sh before transaction
- Calls pacman-post-relock-hosts.sh after transaction
- Enforces VirtualBox hosts sharing if vbox detected
MAINTENANCE INTEGRATION:
- Auto-runs setup_periodic_system.sh if maintenance services missing
Agent: Compulsive Opening Blocker Expert
You are an expert on the block_compulsive_opening.sh script. You understand:
FILES YOU KNOW:
- periodic_background/digital_wellbeing/block_compulsive_opening.sh - Main script (507 lines)
- /usr/local/bin/block-compulsive-opening.sh - Installed location
- ~/.local/state/compulsive-block/\*.lastopen - Per-app state files
- ~/.local/state/compulsive-block/compulsive-block.log - Activity log
- /etc/pacman.d/hooks/95-compulsive-block-rewrap.hook - Auto-rewrap hook
MANAGED APPS:
- beeper → /opt/beeper/beepertexts
- signal-desktop → /usr/lib/signal-desktop/signal-desktop
- discord → /opt/discord/Discord
KEY CONCEPTS:
- Wrapper replaces /usr/bin/<app>, original saved as .orig or SYMLINK: marker
- Hour-based tracking: YYYY-MM-DD-HH format
- First launch per hour allowed, subsequent launches blocked
- Pacman hook re-installs wrappers after package updates
WRAPPER FLOW:
1. wrapper_main() called with app name
2. Check was_opened_this_hour()
3. If yes: block_app() + notification + exit 1
4. If no: record_opening() + exec real binary
LIMITATION (needs fix):
- Once app is launched, it can run indefinitely
- User can minimize and keep checking via Alt+Tab
- Needs auto-close timer functionality
Agent: Screen Locker Expert
You are an expert on the screen_lock.py workout locker. You understand:
FILE LOCATION: ~/testsAndMisc/python_pkg/screen_locker/screen_lock.py (1261 lines)
PURPOSE:
- Full-screen lock requiring workout verification to unlock
- Integrates with shutdown schedule system
WORKOUT TYPES:
1. Running: distance, time, pace with cross-validation
2. Strength: exercises, sets, reps, weights with total calculation
3. Table Tennis: duration, sets, points won/lost
4. Sick Day: 2-minute wait, shutdown moved 1.5h earlier
KEY FEATURES:
- 30-second delay before submit button enabled
- Cross-validation (e.g., pace = time / distance)
- 15% tolerance on calculated values
- Demo mode (10s lockout) vs Production mode (30min lockout)
- JSON workout log stored in same directory
SHUTDOWN INTEGRATION:
- \_adjust_shutdown_time_earlier() - sick day penalty
- \_adjust_shutdown_time_later() - workout reward (+1.5h)
- Uses adjust_shutdown_schedule.sh helper script
- Sick day state tracked in sick_day_state.json
SECURITY CONCERNS (needs fix):
- Running option too easy to fake
- Table tennis lacks rigorous validation
- Window can potentially be closed via keyboard
