Security Hardening

All shell configs are hardened against the CIS Linux Benchmark §5.4 (Linux) and PowerShell STIG (Windows). Controls applied:

Control	Linux (bash/zsh/tcsh)	PowerShell
Session timeout	TMOUT=900 (15 min, readonly)	—
Default umask	umask 027	—
History privacy	HISTCONTROL=ignorespace:erasedups / setopt HIST_IGNORE_SPACE	AddToHistoryHandler drops lines matching password|token|secret|…
History size cap	HISTSIZE=1000 / SAVEHIST=1000	MaximumHistoryCount 1000
History persistence	—	HistorySaveStyle SaveIncrementally
PATH safety	Strips . and empty segments	—

Note: trim_at in both Starship configs uses .local — replace with your actual domain if needed.

Prerequisites

• A Nerd Font installed and enabled in your terminal
  (configs use JetBrains Mono Nerd Font)

Omarchy (Full Desktop Backup)

omarchy/ mirrors ~/.config for an Omarchy Linux install — Hyprland, Waybar, Walker, terminals, and every other app Omarchy templates into your config, plus custom hooks/themes. See omarchy/README.md for restore and update steps (short version: ./omarchy/install.sh).
