# Phase 1: Grundgeruest + Tippmechanik Verification Report

**Phase Goal:** Eine spielbare Tipp-Uebung im Browser, die ohne API funktioniert
**Verified:** 2026-03-29T11:18:00Z
**Status:** passed
**Re-verification:** No -- initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Die App startet via `npm run dev` und ist von aussen unter `http://<vps-ip>:5173` erreichbar | VERIFIED | vite.config.ts: `server: { host: "0.0.0.0", port: 5173 }`; package.json: `"dev": "vite --host"`; TypeScript compiles cleanly (`tsc --noEmit` passes) |
| 2 | Begleitfigur und Tastatur-Layout sind waehlbar und die Auswahl bleibt nach Browser-Reload erhalten | VERIFIED | screens.ts renders 4 companion cards from characters.ts, layout toggle DE/CH in HTML+JS, saveProgress on click, initApp checks selectedCharacter to skip welcome on reload |
| 3 | Stufe 1 (F, J, Leertaste) ist spielbar: Buchstaben erscheinen einzeln, richtiger Tastendruck loest sie auf, falscher Tastendruck tut nichts | VERIFIED | levels.ts level 1: `newKeys: ["f", "j", " "]`; typing.ts handleKeyPress returns correct/incorrect; screens.ts adds dissolve animation on correct, ignores wrong key (no letter change) |
| 4 | Nach 8-12 richtigen Buchstaben gilt die Uebung als abgeschlossen und Stufe 2 wird freigeschaltet | VERIFIED | typing.ts generates 8-12 letters; exerciseComplete triggers handleLessonComplete in app.ts; advances currentLevel and adds to completedLevels in IndexedDB |
| 5 | Die Wald-Uebersicht zeigt den Stufenstatus (locked / current / completed) korrekt an | VERIFIED | scene.ts getLevelStatus returns status from progress; renderLevelMap creates cards with level-card--locked/current/completed CSS classes; main.css styles each state distinctly |

**Score:** 5/5 truths verified

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| (none found) | - | - | - | - |

No TODOs, FIXMEs, placeholders, console.logs, or stub implementations detected in source files.

### Human Verification Required

### 1. Visual Welcome Screen

**Test:** Open app in browser, verify 4 companion cards display with emojis and names in a 2x2 grid
**Expected:** Cards show fairy, unicorn, fox, owl emojis with German names; clicking highlights with green border; DE/CH toggle works
**Why human:** Visual layout, spacing, color appearance cannot be verified programmatically

### 2. Typing Exercise Flow

**Test:** Select a companion, go to forest, start level 1; type correct and incorrect keys
**Expected:** Letters appear one at a time with float animation; correct key dissolves letter with scale-up effect; wrong key does nothing to letter but shows press animation on keyboard; after 8-12 correct letters returns to forest with level 1 completed
**Why human:** Animation smoothness, timing feel, overall UX flow cannot be verified with grep

### 3. Forest Level Map After Completion

**Test:** Complete level 1 and return to forest overview
**Expected:** Level 1 shows checkmark (completed), Level 2 shows arrow (current) with gold border, Levels 3-6 show lock (locked) with reduced opacity
**Why human:** Visual status indicators and color distinction need human eyes

### 4. Persistence After Reload

**Test:** Select companion + layout, complete a level, reload the browser
**Expected:** App skips welcome screen, goes directly to forest, progress preserved (completed levels still shown)
**Why human:** Full IndexedDB persistence lifecycle needs browser testing

### 5. External Network Access

**Test:** Access `http://<vps-ip>:5173` from another machine
**Expected:** App loads and is fully functional
**Why human:** Network accessibility depends on VPS firewall configuration

### Gaps Summary

No gaps found. All 5 success criteria are verified at the code level. All 25 phase requirements (FNDN-01 through PLSH-06) are satisfied with substantive implementations. All key links between modules are wired and functional. All 37 tests pass. TypeScript compiles without errors. No anti-patterns or stub code detected.

5 items flagged for human verification covering visual appearance, animation quality, persistence lifecycle, and network accessibility.
