Is there any SEDE query that can answer the part of this question which says “How can I get a count of how many questions I have voted to close or delete, and how many of those questions have stayed closed/deleted vs. those that have been reversed?”
@EkadhSingh-ReinstateMonica you don't have close/delete vote history for currently deleted posts but you can use the 2021 version I show here meta.stackexchange.com/a/234794 to get thet closed questions and extend that with delete events. What is left then looking for re-open / undelete events that are later then the posthistory row that has the closure or delete.
@RandomPerson Please don't ping mods for stuff that's already been flagged (and especially for non-urgent things). The flags will be handled when someone's available to do so.
@RandomPerson done, TBH I didn't check whether I could reproduce it on another site, but bugs like that are rarely site-specific. This is no exception.
RIP SO UserVoice. The site now gives an error "This UserVoice instance is no longer available."
@Glorfindel I guess now you can code your edit script to replace old links with archive links. (See this chat message for some URL modifications that may be necessary.)
