What happens to it
The fight is read once and kept. Every run that arrives this way is labelled as an upload rather than as a leaderboard entry, and the two are counted separately for the rest of their lives.
That labelling is the point. The measurements on this site come off ranking boards, which are the top of the spec by construction and not a picture of how the spec is played. Runs arriving here are the correction, so the guide gets more honest as they accumulate with nobody editing it.
It also holds the thing a leaderboard structurally cannot: a wipe. Every ranked run in the corpus is a kill, because a board only records kills, so nothing measured so far shows what a fight going wrong looks like.
Only public reports can be read, and only fights with a Preservation Evoker in them are offered, because that is the one spec this site measures. See the guides for what a run gets compared against.
