Handle is how the caller appears on this board: their chosen handle, falling back to their username, on a user board; their org id on the global board. Present even when unlisted — this is the caller looking at themselves.
Listed says whether the caller is publicly visible on this board: opted in on a user board, org opted in (or the viewer is a platform admin) on the global one. False is the prompt to offer the opt-in, and explains an unranked global self.
Metric is whichever of the three values above the board was ranked by, so a client can compare the caller against the rows without re-reading the request. Metric <= 0 is exactly the case that leaves Ranked false.
OfTotal is the size of the universe Rank is out of — "rank N of OfTotal". On a user board that is the org's users with any usage in the window; on the global board it is every active org for a platform admin, and the count of opted-in orgs for everyone else.
Rank is the caller's 1-based standing, computed as (subjects whose windowed metric strictly exceeds the caller's) + 1. It is exact against the whole ranked universe, not just the returned page, so it can far exceed len(rows). Read it only when Ranked.
Ranked is false when the caller holds no position: they had no usage in the window, or (on the global board) their org has not opted into public listing and so is not ranked against a set it never joined. Rank is then 0 and means nothing.
