+# Navigation — Return-Kontext (Rücksprung)
+
+**Stand:** 2026-05-20  
+**Status:** Spezifikation + Phase 1–2 umgesetzt  
+**Ziel:** In der PWA (ohne Browser-Back) zuverlässig an den fachlichen Ausgangspunkt zurückkehren — inkl. sinnvollem Label und optional UI-State.
+
+---
+
+## Problem
+
+Viele Flows navigieren von Kontext A zu Editor/Detail B (z. B. Übungsliste → Modulbearbeitung). Die Zielseite kennt A nicht und bietet nur einen **fest verdrahteten** Zurück-Link (z. B. immer „Modul-Bibliothek“). In der installierten PWA fehlt zusätzlich die Browser-Chrome.
+
+Betroffen u. a.:
+
+- Übungsliste → Modul anlegen/bearbeiten
+- Planung → Einheiten-Editor (teilweise gelöst via `planningReturn`)
+- Modals mit Speichern + Redirect auf Vollseite
+
+---
+
+## Strategie (Hybrid)
+
+| Mechanismus | Wann |
+|-------------|------|
+| **Expliziter Return-Kontext** (`appReturn` in Router-State) | Seitenwechsel, bei denen das Ziel einen fachlichen Rücksprung anbieten soll |
+| **History-Back** (`navigate(-1)`) | Fallback, wenn kein Kontext gesetzt ist und History-Eintrag existiert |
+| **Default-Pfad** | Fallback der Zielseite (z. B. Modul-Bibliothek) |
+| **Modal schließen** | Overlays/Peek — kein Routing-Return |
+
+**Nicht** als alleinige Lösung: reines Browser-Back (History durch `replace`, Deep Links, Reload unzuverlässig).
+
+---
+
+## Datenmodell
+
+Router-State-Schlüssel: **`appReturn`**
+
+```javascript
+{
+  v: 1,                          // Schema-Version
+  path: '/exercises',            // Ziel-URL (inkl. Query, falls nötig)
+  label: 'Zurück zur Übungsliste', // Anzeige im UI (vollständiger Satz)
+  kind: 'exerciseList',          // optional: Typ für erweiterte Wiederherstellung
+  payload: { ... }               // optional: kind-spezifische Daten
+}
+```
+
+### `kind`-Werte (erweiterbar)
+
+| kind | payload | path-Ableitung |
+|------|---------|----------------|
+| `exerciseList` | — | `/exercises` (Filter/Auswahl via sessionStorage) |
+| `planningHub` | `buildPlanningHubReturnState(...)` | `planningHubPathFromReturnState(payload)` |
+| `trainingModulesList` | — | `/planning/training-modules` |
+| `planTemplatesList` | — | `/planning/plan-templates` |
+| `frameworkProgramsList` | — | `/planning/framework-programs` |
+| `settings` | — | `/settings` |
+| `dashboard` | — | `/` |
+| `mediaLibrary` | — | `/media` |
+| `trainingRun` | `{ unitId }` | `/planning/run/:unitId` |
+| `currentLocation` | — | aktuelle Route (z. B. Einheiten-Editor) |
+| (frei) | — | `path` direkt gesetzt |
+
+### Legacy-Kompatibilität
+
+Bestehendes Feld **`planningReturn`** (Planung ↔ Einheiten-Editor) wird beim Lesen in `appReturn` **bridged** — keine Big-Bang-Migration nötig.
+
+---
+
+## API (Frontend)
+
+Zentrale Datei: `frontend/src/utils/navReturnContext.js`
+
+| Funktion | Zweck |
+|----------|--------|
+| `buildNavReturnContext({ path, label, kind?, payload? })` | Kontext-Objekt erzeugen |
+| `buildExercisesListReturnContext()` | Standard-Rückkehr Übungsliste |
+| `buildPlanningHubReturnContext(hubState)` | Planungs-Hub inkl. Filter-Query |
+| `buildTrainingModulesListReturnContext()` | Modul-Bibliothek |
+| `readNavReturnFromLocation(location)` | Kontext aus `location.state` (+ Legacy) |
+| `resolveNavReturnTarget(location, fallback)` | `{ path, label }` für UI |
+| `goNavReturn(navigate, location, fallback?)` | Programmatischer Rücksprung (priorisiert: Kontext → History → Fallback) |
+| `navigateWithAppReturn(navigate, to, returnContext, options?)` | Navigation mit gesetztem `appReturn` |
+| `preserveAppReturnOnNavigate(navigate, location, to, options?)` | Weiterleiten, bestehenden Kontext behalten (z. B. nach `replace`) |
+
+UI-Komponente: **`PageReturnButton`** — app-typischer Zurück-Schalter (Button mit Pfeil, kein Router-Link).  
+Links **zum** Ziel: **`NavStateLink`** mit `returnContext` der Quellseite.
+
+### Editor-Aktionen
+
+Auf Vollseiten-Editoren mit **`FormActionBar`** (`placement="bottom"`) oder **`PageFormEditorChrome`**:
+
+- **Kein** separater Zurück-Link/Button oben (wirkt in der App redundant)
+- **Abbrechen** → `goBack()` / `goNavReturn(...)` (Einsprungspunkt)
+- **Speichern & Schließen** → nach erfolgreichem Save ebenfalls `goBack()`
+- Sticky Action Bar unten nutzen
+
+**PageReturnButton** nur auf **Leseseiten** ohne Editor-Leiste (z. B. Übungsdetail, Einstellungen-Unterseiten, Trainingsablauf).
+
+---
+
+## Regeln für Entwickler
+
+1. **Jede Navigation** von Kontext A zu Editor B, wo der Nutzer „weitermachen“ soll, setzt `appReturn` (oder nutzt `navigateWithAppReturn`).
+2. **Zielseite** zeigt `PageReturnButton` mit sinnvollem **Default-Fallback** (Bibliothek/Hub).
+3. **Nach Create + `replace: true`:** Return-Kontext mit `preserveAppReturnOnNavigate` erhalten.
+4. **Modals:** Schließen reicht; Redirect nach Speichern = Seiten-Navigation → Return setzen.
+5. **Kein Return-Kontext** in `location.state` für interne Bibliothek → Detail → Bearbeiten, wenn Herkunft = offensichtliche Elternliste (Default-Fallback genügt).
+6. **UI-State** (Filter, Auswahl): weiter über bestehende Session-Mechanismen (z. B. `exerciseListSessionState`), nicht im Return-Payload duplizieren, außer kind erfordert Query-Reconstruction (Planung).
+
+---
+
+## Umsetzungsstand
+
+### Phase 1 (Pilot)
+
+- [x] Spec + Utility + Tests
+- [x] `PageReturnButton` (ersetzt Link-Variante)
+- [x] Übungsliste → Modul speichern → Modul-Editor
+- [x] Planung: `SaveExercisesAsModuleModal` leitet Return-Kontext weiter
+- [x] `TrainingUnitEditPage`: `goBack` über `goNavReturn` (Legacy-bridge)
+
+### Phase 2 (Flows verbinden)
+
+- [x] Listen → Editoren: Übungen, Module, Vorlagen, Rahmenprogramme
+- [x] Dashboard → Übung bearbeiten / Trainingsablauf / Einheit bearbeiten
+- [x] Einstellungen-Unterseiten (Rechtliches, Systeminfo)
+- [x] Trainingsablauf + Coach-Modus (`trainingRun`, Planungs-Fallback)
+- [x] Medienbibliothek → verknüpfte Übungen/Einheiten
+- [x] `ExercisePeekModal` → Vollseite mit Return
+- [x] Editoren: Abbrechen + Speichern & Schließen → Einsprungspunkt
+
+### Optional (später)
+
+- Globaler Zurück-Button in App-Chrome (Mobile)
+- Nach Speichern: explizite Aktion „Zurück zum Ausgang“ im Toast
+
+---

+- Session Übungsliste: `frontend/src/utils/exerciseListSessionState.js`
+- PWA-Kontext: `docs/FACHLICHE_NUTZERFUNKTIONEN.md`, App-Shell in `App.jsx`
