It automatically and instantly resets

The missing option is what happened.

Is your clock one of the digital ones that automatically sets itself on daylight saving time?

If it is, it got to 2 a.m., sprang forward to 3 a.m.., and because it never was 2:30 a.m., the alarm never rang. However, it might have rung the next time it was 2:30 a.m., during the wee hours Monday.

If your clock is one of the old-fashioned spring-driven wind-up clocks, the alarm rang at 2:30 a.m. standard time. It had to be "sprung forward" to daylight time manually.

Maybe it will sound in the extra hour going back to standard time.

I was curious how the phone would process the task when 2:30am did not occur on that date.

My conjecture is that the phone decided to wake me two-and-a-half hours after midnight.

I think that was a fair call.
