 - Direct pushes to `main` or `master` branches

 - Shell script syntax with `shellcheck`
 - Code formatting with `shfmt` (2-space indentation, no tabs)
 - Optional checks: `checkbashisms`, syntax validation

 - Executable files with shell shebangs (`#!/bin/bash`, `#!/bin/sh`, etc.)

 This repo automates Linux desktop bootstrap, hardening, and i3 setup. It’s primarily Bash scripts with idempotent installers, systemd units, and policy guardrails. Use these notes to work effectively with the codebase.

 ## Big picture
+
 - fresh-install/: end-to-end bootstrap for Arch/Ubuntu workstations. Reads package lists, configures pacman/makepkg, sets up GPU drivers, i3, hosts guard, pacman wrapper, and useful services. Example: `fresh-install/main.sh` orchestrates most steps and sources `detect_gpu*.sh`.
 - hosts/: manages a highly-opinionated `/etc/hosts` via StevenBlack upstream with custom edits, plus “guard” friction:
  - `hosts/install.sh` builds and locks `/etc/hosts` (immutable/append-only; selective unblocks; custom blocks).
@ -15,11 +16,13 @@ This repo automates Linux desktop bootstrap, hardening, and i3 setup. It’s pri
 - i3-configuration/: installs i3 and i3blocks configs with small font sizing logic (`i3-configuration/install.sh`).

 ## Conventions you should follow
+
 - Bash style: use `set -e` or `set -euo pipefail`, re-exec with sudo if not root, be idempotent, and log to `/var/log/*` with timestamps. Examples: `setup_periodic_system.sh`, `hosts/guard/setup_hosts_guard.sh`.
 - Install via templates: scripts under `scripts/system-maintenance/bin` and `.../systemd` are templates. The setup script substitutes placeholders like `__HOSTS_INSTALL_SCRIPT__` and `__PACMAN_WRAPPER_INSTALL__` before installing to `/usr/local/bin` and `/etc/systemd/system`. Don’t edit installed copies directly; modify templates and the setup script.
 - Package lists: `fresh-install/pacman_packages.txt` and `aur_packages.txt` treat any line not starting with lowercase alnum as a comment.

 ## Core workflows (what to run)
+
 - Fresh machine: run from repo root
  - `fresh-install/main.sh` (bootstraps configs, GPU, hosts, i3, pacman wrapper, services). It assumes the repo is at `~/linux-configuration` in some steps.
 - Periodic services: `sudo scripts/setup_periodic_system.sh` (installs timer, startup service, hosts monitor, and browser pre-exec wrapper; then performs an initial run).

 - i3 config: `i3-configuration/install.sh` (copies `i3` and `i3blocks`, adjusts font size; installs required tools conditionally for Arch/Ubuntu).

 ## Integration points and gotchas
+
 - Pacman interception: `pacman_wrapper.sh` sets `PACMAN_BIN=/usr/bin/pacman.orig` and symlinks `/usr/bin/pacman` -> wrapper. Keep this invariant when changing the wrapper.
 - Hosts hooks: Wrapper calls `/usr/local/share/hosts-guard/pacman-pre-unlock-hosts.sh` and `...post-relock-hosts.sh` if installed; keep paths stable or update both installer and wrapper.
 - Logs: check `/var/log/periodic-system-maintenance.log` and `/var/log/hosts-file-monitor.log` for service behavior; timer and services live under `scripts/system-maintenance/systemd/` (templates).
 - Browser pre-exec: setup creates `/usr/local/bin/browser-preexec-wrapper` and symlinks common browser names to it; it silently re-runs the hosts installer before launching the real binary in `/usr/bin`.

 ## Patterns to reuse when adding features
+
 - Follow the sudo re-exec + idempotent install pattern from `setup_periodic_system.sh` and `hosts/guard/setup_hosts_guard.sh`.
 - Add new periodic behaviors as templates under `scripts/system-maintenance/bin` and `.../systemd`, then extend `setup_periodic_system.sh` to install/enable them.
 - Extend package policy by updating `scripts/digital_wellbeing/pacman/pacman_blocked_keywords.txt` or by adding `check_for_<pkg>` + `prompt_for_<pkg>_challenge` blocks in the wrapper.
 - Run `scripts/meta/shell_check.sh` to detect things to fix before committing.

 - 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-bind-mount.service - Read-only bind mount
- hosts/guard/pacman-hooks/*.sh - Pre/post transaction hooks for pacman

+
 - 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

 The installer will check for required dependencies:

 This system is designed to be difficult to bypass:

 ### 1. **Immutable State Files**
+
 - State files are protected with `chattr +i` (immutable flag)
 - Cannot be edited even by root without removing the flag first
 - Automatically re-applied after each update

 ### 2. **Auto-Restart Service**
+
 - Systemd service automatically restarts if killed
 - Runs continuously in the background
 - Starts automatically on boot

 ### 3. **Hosts File Integration**
+
 - Integrates with the repository's hosts guard system
 - Uses immutable `/etc/hosts` file
 - Cannot be easily bypassed by changing DNS

 ### 4. **Process Integrity**
+
 - Monitors actual active windows, not just running processes
 - Detects if you switch away from work applications
 - VS Code requires specific repository to be open

 ### 5. **Decay Mechanism**
+
 - Using Steam/distractions consumes your earned work time
 - Forces sustained work habits, not just one-time work sessions
 - Fair: 30 minutes of decay per hour of distraction usage

 ### 6. **Locked Configuration**
+
 - Configuration is embedded in the installed script
 - Cannot be easily modified without reinstalling
 - Protected script location in `/usr/local/bin`

 Technically yes, but it's designed to make bypassing more effort than just doing the work:

 - You'd need to fake window activity (complex)
