====== v6.7.20: Snap-aim Jump rework ======

**Deployed player-facing update.** Reviewed October 5, 2026. At 15:11 PDT, Room 1 ran v6.7.20 and Rooms 2–4 ran its cumulative v6.7.21 bridge. This is a dated observation, not a live rollout feed; use [[status:start|Live lobbies]].

===== Player changes =====
  * Redefines [[commands:jump|.jump]] around sustained snap-aim patterns rather than requiring nearly all circles.
  * Includes circle-to-slider, slider-to-circle and slider-to-slider jumps, accounting for slider paths, repeats, speed changes and the cursor's exit position.
  * Farm and Jump remain separate: Farm score, map title and mapper do not determine Jump classification.
  * Prefers maps **under 90 played seconds, with no Jump preference minimum**, and perceived AR 9–10. These are soft preferences, not eligibility gates.
  * Uses weighted variety instead of repeatedly selecting only the highest Jump score. Feedback and global successful-clear weighting still matter.
  * Keeps fresh strong Jump evidence ahead of relaxed fallback. Last-ten played/skipped avoidance, playlist reservations, song spacing, stars and hard length filters remain.
  * When the tier exceeds the 1,200-candidate cap, samples eligible maps instead of permanently retaining only the highest scores.
  * Does not add pre-play ratings or automatically turn skips into bad ratings. Mania style behavior is unchanged.

===== Dated catalog analysis =====
Reanalysis used the active Standard catalog, not the separate expanding research database. It analyzed 92,896 usable cached charts; missing/invalid/non-native or identity-failing inputs were excluded. No live database promotion was performed.

For the analyzed 4.5–5.5★ band, at most 240 played seconds, at least 10,000 global passes and the eight-year age filter, before the runtime cap:

^ Tier ^ Before ^ v6.7.20 ^
| Strong Jump | 18 | 2,249 |
| Relaxed-only fallback | 201 | 3,175 |

All 13 available reference difficulties qualified as strong Jump. These are dated eligible-difficulty counts, not guaranteed current pool sizes, expert-labelled accuracy estimates or distinct song counts.

===== Preferences and later operator tuning =====
Jump's default soft bucket is under 90 seconds, with an 80% bucket choice when both groups exist, and a 1.5× perceived-AR 9–10 weight. Longer/lower-AR maps remain possible. DT uses actual playing length and perceived AR.

The separate October 5 [[wiki:duration_policy|operator duration policy]] sets the normal room preference to 90–135 seconds with a 240-second cap; Jump retains its own under-90-second exception. Settings are persistent outside code releases.
