  "changes": [
    "Added install_core_system.sh: installs workout screen locker, hosts blocking, and midnight shutdown timer unconditionally; prompts for steam enforcer, pacman wrapper, i3 config, compulsive block, focus daemon (--all/--none flags bypass prompts)",
    "Removed 9 files: pc_startup_visual_status.sh and its setup script (failed expectations), all thesis_work_tracker artefacts (failed expectations) including systemd unit and 2 test files",
    "Removed dead setup_pc_startup_monitor.sh call from fresh-install/main.sh"
