Goal Achievement
Observable Truths (from ROADMAP.md Success Criteria)
| # | Truth | Status | Evidence |
|---|---|---|---|
| 1 | npm run generate-assets generiert alle Character Sheets und Avatare erfolgreich in src/assets/generated/ |
VERIFIED | scripts/generate-assets.ts exists, imports generateImage from src/api/gemini.ts, reads config via fs.readFileSync. All 9 PNGs exist: 4 character sheets (561-834KB), 4 avatars (512-768KB), 1 style reference (1MB). npm script "generate-assets": "tsx scripts/generate-assets.ts" present in package.json. |
| 2 | Der Willkommens-Screen zeigt echte generierte Avatare statt Platzhalter | VERIFIED | src/companion/characters.ts has 4 static imports of avatar PNGs (import feeLilaAvatar from "../assets/companions/fee-lila/avatar.png" etc.) and avatarUrl field on CompanionDefinition. src/ui/screens.ts renders <img class="companion-card__avatar" src="${c.avatarUrl}"> with onerror fallback to emoji span. CSS .companion-card__avatar styled at 80px round. |
| 3 | Ein Begruessungstext der Begleitfigur wird generiert (deutsch, max 25 Woerter) oder ein Fallback-Text erscheint wenn kein API-Key vorhanden ist | VERIFIED | src/companion/companion.ts exports getGreeting() which calls loadConfig() -> checkRateLimit() -> generateText() -> fallback via getRandomFallbackGreeting(). System prompt enforces "max. 25 Woerter", "Kein Englisch". src/app.ts calls getGreeting(progress.selectedCharacter, db) for returning users and displays result in #forest-greeting-text. 10 fallback greetings in src/companion/fallbacks.ts, all simple German. |
| 4 | Ein Waldelement-Bild kann mit Stil-Referenz generiert werden; bei fehlendem API-Key zeigt die App Fallback-Bilder ohne Absturz | VERIFIED | src/api/gemini.ts generateImage() accepts referenceImages: Blob[], converts to base64 inlineData, sets responseModalities: ["IMAGE"], returns null on failure. src/companion/fallbacks.ts provides getRandomFallbackForestComment(). 7 SVG fallback images exist in src/assets/fallback-images/ (all with 200x200 viewBox, gradient-based, no text elements, under 2KB each). loadConfig() returns null when config unavailable, triggering fallback path. |

Human Verification Required
1. Visual Avatar Display
Test: Open the app in a browser, check that 4 companion cards on the welcome screen show real watercolor-style avatar images (not emoji). Expected: Each card displays a distinct character image (fairy, unicorn, fox, owl) in pastel watercolor style. Why human: Visual quality and style consistency cannot be verified programmatically.
2. Companion Greeting Flow
Test: Select a companion, complete setup, then revisit the app. Verify the forest screen shows the companion avatar and a greeting text. Expected: Avatar image appears next to a short German greeting (either AI-generated or from the fallback pool). Why human: Requires running the app with browser, IndexedDB state, and potentially Gemini API connectivity.
3. Fallback Degradation
Test: Temporarily remove or rename public/config.json, then load the app.
Expected: App loads without errors. Greeting text shows a fallback. No console crashes.
Why human: Requires manual config manipulation and browser testing.
Gaps Summary
No gaps found. All 4 success criteria verified. All 14 requirement IDs (GAPI-01 through GAPI-06, ASST-01 through ASST-04, COMP-01 through COMP-04) are satisfied. 31 tests pass. TypeScript compiles cleanly. All artifacts exist, are substantive, and are wired together.
