Save Playground Comparison

One rated A/B exchange.

Both answers in full, which is the disclosure the comparison consent flag covers: a preference with no answers attached is a datum nobody can later check, and the page's own history list shows the question and the two model ids from these columns.

A row in the comparison history: the question, the pair, the verdict.

Deliberately without the two answers. The list shows a dozen rows at once and none of them renders an answer body, so sending them would move megabytes to draw a few lines of text. There is no detail endpoint either, because the page has no screen that reads one back: a comparison is a judgment that was recorded, not a transcript to resume.
