        // §3.8.4.4: RECURRENCE-ID refers to an instance of a recurring component
        if ('' === $main->getRrule() && [] === $main->getRdates() && [] === $main->getRdatePeriods()) {
            return ["UID '$uid' has a RECURRENCE-ID but its main event does not recur"];
        }
        // §3.8.4.4: RECURRENCE-ID MUST have the same value type as the DTSTART of the recurring component
        if (array_any($events, static fn ($event): bool => $event->isAllDay() !== $main->isAllDay())) {

    
The parameter event, which is an object, should be typehinted.
    

                    
Time to fix: about 1 hour
