// Backend-TODOs (siehe Roadmap unten in diesem File)
|

// ─────────────────────────────────────────────────────────────────────────
|
||||
//
|
||||
// Die folgenden UI-Features sind aktuell als lokaler Stub im
|
||||
// `DeliveryWorkflowBloc` gebaut. Sie persistieren nichts am Server und
|
||||
// gehen verloren, sobald die Detail-Page geschlossen wird:
|
||||
//
|
||||
// * **B1 Bild-Notizen**: Foto-Upload-Endpoint fehlt. Domain-Feld
|
||||
// `DeliveryNote.image_attachment` existiert bereits als
|
||||
// Storage-Key — wir brauchen einen Endpoint, der Multipart-Upload
|
||||
// entgegennimmt und den Key zurückgibt, dann hier
|
||||
// `tourBloc.add(AddDeliveryNote(imageAttachment: key))` aufrufen.
|
||||
//
|
||||
// * ~~B4 Zahlungsmethode beim Abschluss ändern~~ — ERLEDIGT: Die im
|
||||
// Summary gewählte Methode (`paymentMethodOverrideId` im Workflow-State)
|
||||
// reist beim Abschluss am `/complete`-Endpoint mit und wird atomar auf
|
||||
// der Lieferung persistiert (Server prüft existiert + aktiv).
|
||||
//
|
||||
// * **B5 Unterschrift**: Signature-Pad-Bilder (Kunde + Fahrer)
|
||||
// hochladen + auf der Lieferung speichern. Backend hat dafür weder
|
||||
// Felder noch Endpoint. Explizit „nach der Session" verschoben.
|
||||
//
|
||||
// * **B6 Notiz-Templates**: Stammdaten (vordefinierte Notiz-Texte
|
||||
// zum Auswählen). Im alten Stand schon UI-seitig im NoteAddDialog
|
||||
// vorbereitet; aktuell zeigen wir nur das freie Textfeld.
|
||||
//
|
||||
// * **B7 `completeDelivery` im Frontend**: Repository-Methode +
|
||||
// Bloc-Event fehlt. Backend-Endpoint existiert (parameterlos).
|
||||
// Trigger: „Unterschreiben"-Button im Summary-Step — derzeit
|
||||
// SnackBar-Stub.
