- _on_realize implementiert (war nur connected, nicht definiert) - do_unrealize für as_file() Context-Manager-Cleanup - threading.Lock für _greetd_sock Race Condition - TOML-Parsing-Fehler abfangen statt Crash - last-user Datei: Längen- und Zeichenvalidierung - detect_locale: non-alpha LANG-Werte abweisen - exec_cmd Plausibility-Check mit shutil.which - Exception-Details ins Log statt in die UI - subprocess.run Timeout für Power-Actions - Sequence[Path] statt tuple[Path, ...] in get_sessions - Mock-Server _recvall für fragmentierte Reads - [behavior]-Config-Sektion entfernt (unimplementiert) - Design Decisions in CLAUDE.md dokumentiert
