📊 AUDIT RESULTS
═══════════════════════════════════════════════════════════════════════════

Vulnerabilities Found:    2 CRITICAL
Vulnerabilities Fixed:    2/2 (100%)
Tests Created:            4 test scenarios
Documentation:            3 files

SEVERITY RATING
───────────────────────────────────────────────────────────────────────────
Before:  🔴 CRITICAL  (Could corrupt database with invalid values)
After:   🟢 ACCEPTABLE (Strict enum validation in place)


🔍 VULNERABILITIES FIXED
═══════════════════════════════════════════════════════════════════════════

1️⃣  THEME VALIDATION
    Vulnerability: Missing enum validation
    Impact:       Arbitrary strings (3-20 chars) accepted
    Fix:          Strict enum: ["ocean", "sunset", "neon"]
    Status:       ✅ FIXED

2️⃣  ANIMATION SPEED VALIDATION  
    Vulnerability: Missing enum validation
    Impact:       Arbitrary strings (3-20 chars) accepted
    Playability:  Breaks timing logic
    Fix:          Strict enum: ["slow", "normal", "fast"]
    Status:       ✅ FIXED


📁 FILES MODIFIED
═══════════════════════════════════════════════════════════════════════════

✏️  rollerlogic-api/src/routes/wallet-routes.ts
    • Added VALID_THEMES constant
    • Added VALID_ANIMATION_SPEEDS constant
    • Changed theme validation: minLength/maxLength → enum
    • Changed animationSpeed validation: minLength/maxLength → enum
    • Added manual runtime validation (defense-in-depth)
    • Size: +50 lines
