   └─ PHP 8.0+? WordPress 6.0+? Extensions?
       ├─ ✅ Yes → Continue
       └─ ❌ No → Show what's needed, stop safely

2. Check: Are all files present?
   └─ All critical files exist?
       ├─ ✅ Yes → Continue
       └─ ❌ No → Show missing files, stop safely

3. Create: Database tables needed
   └─ Tables created successfully?
       ├─ ✅ Yes → Continue
       └─ ❌ No → Show error, stop safely

4. Success: Plugin is active and safe!

While Plugin Is Active

Every Hour:
1. Check: Are all files still there?
2. Check: Are all tables still there?
3. Found Issues?
   ├─ Can Auto-Repair? → Fix silently
   └─ Can't Auto-Repair? → Show notice

If Fatal Error Occurs

1. Detect: Fatal error in plugin code
2. Log: Save error details
3. Count: Increment error counter
