adminandClaude Sonnet 5 d987b93315 Schülerdokumentation: Einträge, Fehlzeitenbilanz, Datenschutz (Kapitel 5)
Dokumentationseinträge mit Typwahl (Gespräch, Vorkommnis, Förderplan,
Fehlzeit, Elternanruf, Elternbrief), vertrauliche Einträge nur nach
Bestätigung sichtbar, weiche Löschung mit Nachvollziehbarkeit. Fehlzeiten
als Auswertung des bestehenden Anwesenheits-Trackings statt zweiter
Erfassung, mit Schwellenwert-Warnung im Schülerdetail und Dashboard.
Förderplan-Wiedervorlage als Dashboard-Karte. Datenschutz: Löschfristen
mit manueller Bereinigung und DSGVO-Art.-15-Datenauskunft als Export.

Auf Nutzer-Feedback hin ergänzt: Elternanruf mit begleitendem
Gesprächsprotokoll-Dialog (Punkte abhaken, Eindrücke festhalten),
Elternbrief mit Versand-/Rückmeldungs-Tracking, Datei-Anhänge über
LiteDBs Dateispeicher, frei vergebbare Labels zur Nachverfolgung mit
Dringlichkeits-Farbcodierung, sowie eine sichtbare Farblegende für das
bestehende Notenentwicklungs-Diagramm. Dabei einen Absturz behoben:
leere Textfelder lieferten über das Binding null statt "", was beim
Speichern eine NullReferenceException auslöste.
