+| `getFeedPairs` | `GET /auth/feed?lang=&limit=&exclude=` | returns "pairs", the feed unit |
+| `saveProgress` | `POST /auth/progress` | books EP/streak; returns the **milestone contract** (see below) |

+| `setDailyGoal` | `PUT /auth/goal` | Tagesziel (EP/Tag) setzen; Backend klemmt auf 5–500 |
+
+`saveProgress` returns `{ total_ep, level, prev_level, streak_days, streak_increased, daily_ep, daily_goal_ep, goal_just_reached, unlocked_achievements }` — `Feed.jsx` leitet daraus die Feier-Momente ab (Level-Up/Streak/Tagesziel/Achievement). Felder degradieren defensiv: fehlen sie (älteres Backend), greifen lokale Fallbacks.
+
+`src/pages/Profil.jsx` rendert die Begrüßung (`language_target_greeting`), **führt mit Momentum** (`% bis Level X` + Capability-Satz), zeigt Kategorie-Stufen (`stats.categories` + `categoryTier`), Wochenvergleich, Streak-Status, Erfolge-Grid (`getAchievements`) und einen Sound-Toggle.
+
+### Fortschritts-/Feier-System (Momente)
+
+Macht Fortschritt spürbar statt nur zählbar. Bausteine:
+
+- **`src/utils/leveling.js`** — spiegelt die Backend-Level-Kurve (`levelForEp`/`levelInfo`, Level 1 bei 20 EP). Backend ist Single Source of Truth; das ist Fallback + %-Anzeige.
+- **`MilestoneOverlay`** (`components/`) — Vollbild-Feier, getriggert aus der `saveProgress`-Response. Typen: `level` / `streak` (Schwellen 3/7/14/30/50/100/200/365) / `goal` / `achievement`. Konfetti via `utils/confetti.js`.
+- **`EpFloat`** — „+N EP" schwebt am Bestätigen-Button auf; EP-Badge zählt hoch (`hooks/useCountUp.js`).
+- **`SessionSummary`** — ersetzt die End-Sackgasse mit Zahlen + Story-Zeilen.
+- **Combo** + variables Lob/ermutigendes Fehler-Feedback (`utils/praise.js`, dort auch `categoryTier`/`capabilitySentence`).
+- **`utils/sound.js`** — dezente WebAudio-Belohnung (Mute-Pref in localStorage).
+- **`utils/streak.js`** + **`utils/streakReminder.js`** — Loss-Aversion-Nudge im Feed („Serie endet in X Std") und lokale Tages-Erinnerung via **`@capacitor/local-notifications`** (kein APNs nötig; nur nativ, web no-op — braucht `npx cap sync ios`).

 Several content functions (`getWords`, `getQuestions`, `getActiveLearningPair`, `assetUrl`, …) are **stubs** returning empty/null — content endpoints are not built yet. Don't assume they fetch anything.
