+# Elternabläufe: Mitteilungen und Teilnahmeantworten
+
+## Verhalten
+
+- Die Übersicht zeigt offene Rückmeldungen und drei aktuelle Mitteilungen. Das Archiv unter `/dashboard/mitteilungen` enthält alle für das eigene Konto sichtbaren Meldungen, zwölf pro Seite.
+- Termine können eine Antwort pro Kind oder pro Familie verlangen. Familienzusagen brauchen mindestens einen teilnehmenden Erwachsenen; Absagen speichern 0 Erwachsene. Beide Elternkonten bearbeiten dieselbe Antwort.
+- Die Terminart schlägt bei neuen Terminen eine Antwortart vor. Die Verwaltung kann sie ändern, solange keine Antworten vorliegen. Danach verhindert auch die Server Action einen Wechsel. Normale Terminänderungen erhalten die bisherigen Teilnahmefelder.
+- Kinderantworten werden für alle eigenen aktiven Kinder gemeinsam in einer Transaktion gespeichert. Eigene und fremde Kinder dürfen nicht gemischt werden. Frist, Terminstatus, Haushalt, Kita und aktiviertes Terminmodul werden serverseitig geprüft.
+- Ohne eigene Rückmeldefrist gilt der Terminbeginn. Nach Fristablauf bleiben die Antworten im Kalender lesbar. Die Eingabe ist in Monatsansicht, Liste und Agenda erreichbar.
+- Empfängergruppen sind Eltern, ErzieherInnen oder beide. Die Gruppe steuert App-Anzeige, Lesestatus-Aktion, Anhänge und optionalen E-Mail-Versand. Admins können sämtliche Meldungen der eigenen Kita zur Verwaltung sehen. Eltern mit Koordinationsrolle gehören mit ihrem Haushalt zur Elterngruppe; Erzieherkonten gehören zur Erziehergruppe.
+- Teilnehmerhinweise werden nur bei einer Zusage des Haushalts oder für Admin/Koordination an den Kalender-Client übertragen.
+
+## Bestehende Daten und Schemaaktualisierung
+
+Das Projekt verwendet weiterhin `prisma db push`; es besitzt keine Prisma-Migrationshistorie. Der vorhandene Produktionsstart aktualisiert das Schema automatisch. Die neuen Pflichtfelder haben kompatible Defaults: bisherige Termine bleiben `CHILD`, bisherige Meldungen erhalten `ALLE`. Bestehende Kinderantworten werden nicht verändert.
+
+Für eine kontrollierte, einmalige Aktualisierung einer Datenbank mit dem bisherigen Schema liegt zusätzlich die additive SQL-Datei `prisma/updates/20261007_parent_flows.sql` vor. Sie ist eine Alternative zum ersten `db push`, kein nachträglich anzuwendender zweiter Schritt. Beispiel:
+
+```sh
+psql "$DATABASE_URL" -v ON_ERROR_STOP=1 --single-transaction -f prisma/updates/20261007_parent_flows.sql
+npm run prisma:generate
+```
+
+Die Datei gehört bewusst nicht in `prisma/migrations`: Eine Einführung von `prisma migrate deploy` würde zuerst eine Baseline für bereits existierende Datenbanken verlangen.
+
+## Verifikation
+
+```sh
+npm run test:parent-flows
+TEST_DATABASE_URL=postgresql://USER@127.0.0.1:PORT/TESTDB npm run test:parent-flows:integration
+npx tsc --noEmit
+npm run build
+```
+
+Die Integrationstests benötigen eine Node.js-Version mit experimentellem Modul-Mocking (hier geprüft mit Node.js 26), eine ausdrücklich über `TEST_DATABASE_URL` gesetzte lokale PostgreSQL-Testdatenbank und das aktuelle Schema. Sie legen eigene Kitas mit zufälligen IDs an und entfernen ausschließlich diese Testkitas wieder. Kein automatischer Zugriff auf `DATABASE_URL` ohne Testfreigabe.
+
+Die Tests prüfen Erwachsenenanzahl, gemischte Kinderantworten, gemeinsame Familienantworten, Fristablauf, Terminabsage, Moduldeaktivierung, Kita-/Haushaltsgrenzen, gesperrte Antwortart einschließlich paralleler erster Rückmeldung, erhaltene Terminoptionen sowie verweigerte Team-Meldungen und Anhänge für Eltern. E-Mail-Empfänger werden anhand derselben Gruppenregeln geprüft; es werden keine echten E-Mails verschickt.
+
+Zusätzlich im Browser geprüft: Familienzusage, unterschiedliche Antworten für zwei Kinder, verschwundene offene Hinweise, Lesen/Ändern der gemeinsamen Antwort aus einem zweiten Elternkonto, abgelaufene Eingabe, Kalender-Monats- und Agendaansicht, Lesestatus, Archivnavigation, Verwaltungsauswertung, gesperrte Antwortart und Eltern-/Erzieher-Empfängertrennung. Die Rückmeldeformulare und Übersicht wurden auch bei 390 Pixeln Breite visuell geprüft.
