Observability Coverage Check

Analyze PHP code for observability gaps that hinder debugging, monitoring, and incident response in production.

Detection Patterns

1. Unstructured Logging

<?php

declare(strict_types=1);

// BAD: Raw error_log with unstructured output
final class PaymentService
{
    public function charge(Money $amount): void
    {
        error_log('Payment failed for amount ' . $amount->cents());
