 ====== How maps are selected ======
-Selection starts with the active source catalog and the room's hard filters: game mode, key count where applicable, difficulty, playable length, pass-count policy, age policy when enabled, and availability. [[commands:pool|.pool]] gives the current room settings.
+Pool eligibility, freshness, player feedback, and mode-specific preferences work together to select maps.
+^ Availability | All lobbies; filters vary by room |
+^ Documentation status | Current behavior |

 ===== Freshness and preference =====
-The bot avoids recent played or skipped maps, excludes maps already reserved in the visible playlist, and spaces songs. Player [[wiki:ratings|feedback]] affects weighting. Mania also has [[wiki:mania_styles|structural preferences]] and experimental [[wiki:mania_farm|farm evidence]]. Preference cannot make an ineligible map pass the hard filters.

 ===== Why the pool changes =====
 The catalog, active difficulty range, and filters all influence eligible counts. Research coverage grows over time; experimental classifications can change after validation. See [[wiki:style_fallback|fallback]] and [[troubleshooting:repeats|repeated maps]].
+===== Sparse catalog expansion =====
+A separate sparse-pool mechanism can progressively broaden playable length and configured ranked-map age while retaining star-rating, pass-count, quality, status, key-mode, and download boundaries. It prefers the original candidates before expanded ones. This catalog expansion is different from [[wiki:style_fallback|style exhaustion fallback]], which softens style evidence within the resulting eligible catalog.
+===== Worked example =====
+Type ''.pool'' to inspect the active range and filters. A style or source request still has to find eligible maps inside the applicable selection policy.
+===== Limitations =====
+Sparse-catalog expansion and style exhaustion fallback are separate mechanisms. Research evidence and pool counts can change.
