**Status:** human_needed
**Re-verification:** No -- initial verification
## Goal Achievement
### Observable Truths (from Success Criteria)
| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Sounds spielen bei richtigem Tastendruck, Belohnung und neuem Waldelement; Mute-Button funktioniert und Zustand bleibt nach Reload | VERIFIED (code) | playCorrectSound called in screens.ts:217,293; playRewardSound in reward.ts:204; playForestElementSound in scene.ts:48; mute-btn wired in main.ts:24-54 with getSettings/saveSettings persistence |
| 2 | Buchstaben fallen sanft (keine ruckartigen Animationen), Sternenstaub-Animation erscheint bei Erfolg | VERIFIED (code) | @keyframes leaf-fall in main.css:331 with translateX sway; @keyframes stardust in main.css:388 on .falling-letter--dissolve pseudo-elements |
| 3 | Sprachausgabe liest Companion-Text vor wenn aktiviert (Web Speech API, Deutsch) | VERIFIED (code) | speakText in speech.ts:31-53 checks speechEnabled, uses de-DE, rate 0.9, pitch 1.1; called from reward.ts:208 and app.ts:219 |
| 4 | Export und Import funktionieren: Exportieren, Browser-Daten loeschen, Importieren, Fortschritt wiederhergestellt | VERIFIED (code) | exportData in parent.ts:242-262 creates JSON blob download; importData in parent.ts:267-301 validates + confirms + saves; resetAllData in parent.ts:318-324 double-confirms + clears 5 stores |
| 5 | Keine unbehandelten Exceptions in der Browser-Konsole bei normalem Gebrauch | VERIFIED (code) | Global error + unhandledrejection handlers in main.ts:6-16 show error-overlay; all audio functions use try/catch with silent fallback |

### Human Verification Required
### 1. Audio Playback at Correct Touch Points
**Test:** Start a lesson, type correct letters. Complete a lesson to see reward. Return to forest when new element appears.
**Expected:** Short beep on each correct key, ascending melody on reward screen, glitter sound when new forest element renders.
**Why human:** Web Audio API sounds require a browser with audio output.
### 2. Mute Button Persistence
**Test:** Click mute button (bottom-right corner), verify icon changes. Reload page, verify mute state persists.
**Expected:** Icon toggles between speaker and muted speaker; state survives page reload.
**Why human:** Requires interactive browser session to verify visual state and persistence.
### 3. Speech Synthesis for Companion Text
**Test:** Enable speechEnabled in settings (currently defaults to false), navigate to forest screen or complete a lesson.
**Expected:** Companion greeting and reward comment read aloud in German via Web Speech API.
**Why human:** TTS requires audio output and a browser with speech synthesis support.
### 4. Export/Import Round-Trip
**Test:** Open parent area (code 1234), click "Fortschritt exportieren", clear browser data (Application > Clear Storage), click "Fortschritt importieren" and select the exported file.
**Expected:** JSON file downloads, after import progress is restored (current level, sessions, character selection).
**Why human:** Requires interactive file dialogs and manual browser data clearing.
### 5. Leaf-Fall and Stardust Animation Quality
**Test:** Start a lesson, observe falling letters. Type correct letters and observe dissolve animation.
**Expected:** Letters sway side-to-side like leaves (not just float). Stardust sparkle particles appear on correct keypress dissolve.
**Why human:** Animation quality and smoothness require visual assessment.
### 6. Responsive Layout at 700px
**Test:** Resize browser window to less than 700px width.
**Expected:** Keyboard keys shrink, fonts scale down, grid columns adjust.
**Why human:** Layout responsiveness requires visual verification.
### 7. Error Overlay on Exception
**Test:** Open browser console and run `throw new Error('test')`.
**Expected:** Child-friendly overlay with tree emoji and "Oh, der Wald braucht kurz eine Pause..." message appears. Reload button works.
**Why human:** Requires running browser with dev console.
### Gaps Summary
No code-level gaps found. All 13 requirements are satisfied at the implementation level. All artifacts exist, are substantive (no stubs), are properly wired, and data flows through the connections.
The remaining verification is purely behavioral -- confirming that audio plays correctly, animations look smooth, and the export/import round-trip works in a real browser. These items cannot be verified programmatically and require human testing.
