+## Domänenmodell
+
+**Task**
+- `id`, `name`, `date` (nullable, ISO), `status`
+- Status-Enum (`TaskStatus`): `active`, `done`, `inactive`, `past`
+- `past` ist **derived** — wenn `date < today`, liefert `Task::getStatus()` automatisch `past`; der rohe gespeicherte Wert bleibt erhalten (`getRawStatus()`)
+- `past` ist **nicht user-selectable** (siehe `TaskStatus::userSelectableValues()`)
+- Filter `/api/tasks?filter=current` → Tasks ohne `inactive`, sortiert nach `date` aufsteigend (null-first)
+- Default (`/api/tasks`) → alle Tasks, sortiert nach `date` absteigend
+
+## REST-API
+
+| Methode | Route | Zweck |
+|---|---|---|
+| GET | `/api/tasks?filter=current` | aktuelle Tasks (für `/tasks`) |
+| GET | `/api/tasks` | alle Tasks (für `/tasks/all`) |
+| GET | `/api/tasks/statuses` | user-selectable Statuswerte als `string[]` |
+| GET | `/api/tasks/{id}` | einzelner Task |
+| POST | `/api/tasks` | Task anlegen |
+| PUT | `/api/tasks/{id}` | Task aktualisieren |
+| DELETE | `/api/tasks/{id}` | Task löschen |
+| PATCH | `/api/tasks/{id}/toggle` | Status zwischen `active`/`done` togglen |
+
+Request-DTO: `TaskRequest` (name, date `!Y-m-d`, status). Deserialisiert + validiert via `#[MapRequestPayload]`.
+Response-Serialisierung: Symfony Serializer mit `groups: ['task:read']`, Datum als ISO `Y-m-d` String.
+
+## UI-Muster
+
+- **`/tasks`** (Vue + Kotlin): Tasks nach Datum gruppiert in Cards. Datum sitzt als Pill auf dem Top-Border der Card (fieldset/legend-Look). No-Date-Tasks oben in titelloser Card. `showDone` default `false`.
+- **`/tasks/all`** (Vue + Kotlin): Flache Liste mit Edit- und Delete-Icons. `past`-Tasks mit Opacity 0.5, `inactive` kursiv, `done` durchgestrichen.
+- **Icon-Reihenfolge `/tasks` Header**: plus, list, eye, refresh.
+- Kotlin-Screens refreshen auf `Lifecycle.Event.ON_RESUME` via `DisposableEffect` (gegen stale Daten nach Navigation).
+- Status-Labels in Create/Edit kommen aus dem Backend (`/api/tasks/statuses`) — nicht clientseitig hardcoded.
