shellcheck SC2034: - first_time_install.sh: 'type' loop variable also unused in the wifi status loop (we previously fixed 'device' → '_' but left 'type'). Changed to '_ _ state' since neither device nor type is referenced. ESLint no-undef: - app.js: typeof guards don't satisfy no-undef; added updateSystemStats to the /* global */ declaration alongside showNotification. nosec annotation: - web_interface/app.py: app.run(host='0.0.0.0') line changed when we fixed debug=True, giving it a new issue ID. Re-added # nosec B104. pyflakes F401: - scripts/dev/test_pillow_compat.py: ImageFilter was imported but never used in the smoke test. Removed from the import. Codacy API suppressions (false positives on changed lines): - disk_cache.py 0o660 chmod (2x): lines changed when # nosec B103 was added, producing new Semgrep issue IDs. Re-suppressed. - pages_v3.py raw-html-concat: Semgrep does not recognise escape() as a sanitizer; the escape() call IS the correct fix. - app.py flask 0.0.0.0: same line as B104 above; Semgrep rule also re-suppressed.

Exercises the Pillow APIs used throughout LEDMatrix to verify a new
