Adds occasional verified Double Time picks alongside NoMod in Standard Ranked lobbies. DT is an eligible speed variant, not a DT-only map source.

• Automatic DT eligibility starts when the midpoint of the active star range is above 5.5★. At exactly 5.5★ or below, it stays off unless players opt in.
• .dt allows DT at any range; .nm opts out. Overrides reset with the empty-room session.
• With fresh choices in both variant pools, DT has a 25% selection chance and does not follow another DT pick. NoMod remains the majority; this is not a fixed session quota.
• Uses locally calculated actual DT stars and speed-adjusted length, not a fixed multiplier on NoMod stars.
• Playlist items apply their own DT/NoMod settings so speed does not leak into the next normal map. Labels show +DT, and PP lookups and remaining-time estimates follow the variant.
• Normal map/song repeat protection is shared between the NoMod and DT versions.

Current official chart metadata and the cached revision must agree before a DT map enters play. Uncertain or stale evidence falls back safely to NoMod. The initial catalog covers 8,605 cached Ranked Standard charts, before room filters; it is not every map in the Standard database.

Not Farm-only: Farm DT candidates need positive Farm evidence with DT/NC top-play evidence; Stream and Jump have their own qualifying structural evidence. DT and NC evidence share one plain 1.5× DT variant; NC is not queued separately. Mania and Loved do not use mixed DT. See selection, opt-out and safety details.

Included in cumulative v6.7.13, queued at the October 4, 2026, 13:13 PDT review. Neither Standard room was running v6.7.11+ at that snapshot. Occupied rooms wait until empty and idle; newer notes do not prove this feature is already active everywhere.
