library.py hält die Regeln der Web-Bibliothek (53-library.js) als reine Funktionen: Status Angefangen/Ungelesen/Gelesen, Ordner (mehrere je Buch, Reihenfolge aus den verschlüsselten Bibliothekseinstellungen, "Ohne Ordner"), Suche ohne Akzente, sechs Sortierungen mit natürlicher Zahlenordnung, Weiterlesen-Karte aus den zuletzt gelesenen, Bücher/Zeitschriften. library_screen.py zeigt sie an (Tasten 1-4, o, /, s, m, c; Chips und Karte klickbar). Metadaten (Ordner, Seitenzahl, Zeitschrift) und die Ordnerreihenfolge kommen beim Abgleich; fehlt die Länge, rechnet die TUI sie für geladene Bücher aus dem Text (1800 Zeichen je Seite). crypto.encrypt für Stufe 3. 54 Tests, Smoke prüft Ordner/Länge/Prefs gegen den lokalen Server.
