Broadens the preferred duration for shorter DT maps without demoting DT picks that were already preferred.

• Default DT preference becomes 1:00–2:30 of played time; NoMod and Mania retain 1:30–2:30.
• Shorter-than-preferred maps remain possible, and longer eligible maps can appear occasionally.
• The hard limit uses actual played time. A 4:30 source chart becomes 3:00 with DT and can qualify under a 4:00 limit as an occasional longer pick.
• A 6:00 source chart becomes 4:00 with DT and fits that cap. A source duration of 6:01 rounds up to 4:01 with DT and is excluded.
• Stars, source eligibility, DT mix rate, feedback and repeat safeguards remain unchanged. Existing queued picks are preserved.

DT's preferred minimum is the configured minimum divided by 1.5 and rounded up; the preferred maximum remains in played seconds. Existing JSON duration settings apply, with no new setting. This changes preference, not catalog coverage: a length-eligible chart still needs verified DT evidence and must pass every other room filter. See mixed DT and duration policy.

Includes v6.7.9 personal language guidance, v6.7.10 sparse Standard pass-count fallback, v6.7.11 mixed DT and v6.7.12 reduced Mania LN weighting, along with prior patches. All 658 offline tests passed.

Verified snapshot: October 4, 2026, 13:13 PDT. All four workers were healthy and waiting for v6.7.13 at their normal empty-safe gate:

Follow-up at 13:20 PDT: Room 3 had reached v6.7.13; Rooms 1, 2 and 4 remained healthy and waiting on the versions in the table. The Standard DT feature was still pending in both Standard rooms at that check.

Each room waits until continuously empty and idle for at least 30 seconds. Players and spectators are not removed to deploy an update. This table is a dated snapshot, not live telemetry; check each room title and Live lobbies. The shared supervisor's version can differ from worker versions.
