A convert is an osu!standard beatmap played through Mania's converter rather than a chart originally authored for Mania. PoolRotator admits a vetted set supported by repeated top-play evidence and official Mania difficulty attributes.

The chosen columns and converted star rating must match the room. Unsupported key modes are rejected. The chart's actual converted structure is analyzed rather than assuming its Standard structure describes Mania.

In the current rollout, converts appear in Mania Variety only, with native charts kept as the majority: at most three of every ten ordinary Variety picks are vetted converts. Native structural and farm-only pools remain separate while feedback is gathered.

.map identifies chart origin; .pool reports eligible converts. See the convert update and styles.
