Fallback Strategy Audit

Analyze PHP code for missing or insufficient fallback strategies ensuring graceful degradation under failure conditions.

Detection Patterns

1. No Fallback on External Service Failure

// CRITICAL: Exception propagates — no graceful degradation
class ProductService
{
    public function getRecommendations(UserId $userId): array
    {
        return $this->recommendationApi->fetch($userId); // If API down → 500 error
    }
}

// CORRECT: Fallback to cached/default recommendations
