  /**
   * Fires a deterministic alert log entry for every process execution failure.
   * <p>
   * This listener is designed to be simple, stateless, and fast. It does not perform
   * complex logic like rate limiting or cooldowns. Such responsibilities should be
   * handled by external monitoring and alerting systems (e.g., ELK, Prometheus Alertmanager)
   * that can aggregate and filter these structured logs.
   * <p>
   * Note: Logging is only emitted at DEBUG level for testing; production behavior
   * should be provided by business-side extensions.
   * <p>
   * This listener respects the observability configuration switches and will be disabled
   * if observability is turned off.
