Add a self-expiring override system so specific late-night live events (2026 World Cup matches) can be watched without the auto-shutdown killing the PC, without weakening the permanent schedule ratchet: - shutdown-override-manager.sh (add/list/remove): add is friction-gated (typed confirmation phrase + 30s delay, max 12h, max 3 windows) and writes absolute-epoch windows to /etc/shutdown-schedule-overrides.conf. - day-specific-shutdown-check.sh now skips the shutdown decision inside an active window (pruning expired entries) and gained a DRY_RUN guard around rtcwake/poweroff/hibernate for safe testing. i3blocks shutdown_countdown.sh: show the exact next-shutdown clock time (not a relative countdown), show the overridden end time in green when an override is active or will rescue the upcoming shutdown, and make the skip-dates check fork-free (builtin read loop) so the hot path spawns no external processes. install.sh: deploy i3blocks by symlinking each repo file into ~/.config/i3blocks instead of cp -r (the source of silent drift), cd to the script dir so it runs from anywhere, and chmod +x only *.sh so the config file stays 0644. Repair the previously-dead i3blocks regression suite (stale path), update the shutdown assertion to the new absolute-time output, add hermetic override coverage, and keep the <=1-exec fork-count guarantee.

"intent": "Let the PC survive the normal digital-wellbeing auto-shutdown during specific live-event windows (2026 World Cup matches) via self-expiring, friction-gated overrides; surface the exact next-shutdown clock time (or the overridden time) in the i3bar; and make the i3blocks deploy drift-proof so the running scripts can never silently diverge from the repo.",

|
|
"Added a time-boxed override system: shutdown-override-manager.sh (add/list/remove) writes absolute-epoch windows to /etc/shutdown-schedule-overrides.conf; adding requires an exact typed confirmation phrase plus a 30s delay. The generated day-specific-shutdown-check.sh now skips the shutdown decision inside an active window (pruning expired entries) and gained a DRY_RUN guard around rtcwake/poweroff/hibernate for safe testing.",
|
|
"Rewrote the i3blocks shutdown_countdown.sh to show the exact clock time of the next shutdown (e.g. '21:00') instead of a relative countdown, to show the overridden end time in green when an override is active or will rescue the upcoming shutdown, and made the skip-dates check fork-free (bash builtin read loop replacing grep -qxF) so the hot path spawns zero external processes.",
|
|
"Changed install.sh to deploy i3blocks by symlinking each repo file into ~/.config/i3blocks (was cp -r, the source of silent drift), added cd-to-script-dir so it runs from anywhere, and restricted chmod +x to *.sh so the non-executable config file is left at 0644. Reconciled all 18 live files (17 scripts + config) to symlinks.",
|
|
"Repaired the previously-dead i3blocks regression suite: fixed the stale i3-configuration path in both test files, updated the shutdown assertion to the new absolute-time output, added hermetic override coverage, and re-verified the fork-count guarantee (<=1 exec)."
