* fix: six bugs found testing main on a real Pi (ledpi) - Stopping the service now runs cleanup. systemd stops ledmatrix.service with SIGTERM, whose default action ended Python before run()'s finally block, so the update worker, Vegas and the panel were never torn down. main() now turns SIGTERM into KeyboardInterrupt, the Ctrl-C path. - "Now showing" no longer turns into "unknown". display_current_state was only written on a mode change and the web UI reads it with max_age=120, so a live game or a single plugin on screen for longer read as unknown. It is republished every 30 s while unchanged. - Switching Vegas on in the web UI works when it was off at startup. The coordinator was only created at startup; the config watcher now flags it and the render thread creates it. - configure_web_sudo.sh finds reboot and poweroff in /usr/sbin. Run as the web user it could not, silently dropped their rules and still said it granted them, so the web UI's Reboot/Shutdown stopped working. - check_system_compatibility.sh reports installed packages as installed. `dpkg -l | grep -q` under pipefail failed when grep exited early. - A network failure fetching GitHub repo info logs a WARNING, not ERROR.

The dpkg-query stub read $4, but the package name is the third (last) argument. Both now pass on a Pi. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(display): cover the follower, long-render and startup cases Review follow-ups on the ledpi fixes: - The pending Vegas start is applied before the sync-follower branch too (_apply_pending_vegas_init), which skips _is_vegas_mode_active() while a follower is connected but needs the coordinator for the leader's image. - _service_pending_changes(), which runs inside Vegas iterations and long screens, republishes a stale display_current_state as well; the main loop alone could be away for a 240 s Vegas iteration. - The SIGTERM handler is installed after DisplayController() is built, so a stop during parallel plugin loading keeps the default immediate exit.

Scripts
Helper scripts for installing, repairing, diagnosing and developing LEDMatrix. Most users only ever run the one-shot installer (see the project README); everything else here is for troubleshooting or development.
Status key: keep — part of install/runtime or referenced by docs, CI, tests or code; dev-only — for plugin/core development, not needed on a display; diagnostic — run by hand on a Pi when something is wrong.
Directories
| Directory | Status | What it holds |
|---|---|---|
install/ |
keep | The installers: one-shot, services, sudoers/WiFi permissions, cache setup, and the shared lib_*.sh helpers first_time_install.sh sources |
fix_perms/ |
keep | Permission repair scripts, plus the two root helpers the web interface runs through sudo (safe_plugin_rm.sh, safe_pip_install.sh) |
utils/ |
keep | Scripts run by systemd units or the web interface (conditional web start, WiFi monitor, update verify, DNS fix, Pixlet config editor, cache clearing) |
dev/ |
dev-only | Plugin linking, emulator runner, Vegas density audit, Pillow smoke test |
templates/ |
dev-only | dev_preview.html, the page dev_server.py serves |

Candidates for removal
Nothing in the repo (docs, CI, tests, other scripts or code) refers to these. They are kept for now; each one needs an owner decision before it goes.

One-off: adds missing default values to plugin config schemas |
analyze_plugin_schemas.py |
One-off: reports duplicate/inconsistent fields across plugin schemas |
audit_plugins.py |
