no, sequence numbers are completely subjective to a relay, they are literally a record of when they saw an event

i already implemented it, go look:

https://realy.mleku.dev/api#tag/events/GET/api/eventidsbyserial/{start}/{count}

yes it was that simple

and btw, the fact that i came up with it in collaboration with semisol is part of why i'm so salty about his behaviour

anyway, it's in there, and i put it there *so he could sync faster with realy*, you see the tone of that?
