also show Off by default. Neither is a judgement about the game.

Every count here comes from a game we measured — not an estimate.

what the badges and the blanks mean

measured — we watched this happen.
declared — the game says so, and we did not check.
derived — we grouped what the game told us.
A blank is a gap in our measurement, not a no. Each facet spells its own: not identified, not declared, nothing negotiated.
A measured zero is a count. An unknown count is not a zero and never sorts as one.
Open-ended facets list their 20 commonest values. The rest are reachable by search and by URL.
