Checklist: Ranking a mod

• Does the mod require new difficulty attributes?
  • If yes, then we
    • need to add new cached rows for a new set of mod combinations to the database, or
    • need to make realtime difficulty calculation work somehow.
• Does the mod have settings which influence difficulty attributes?
  • If yes, then we need to make realtime difficulty calculation work somehow.
• Does the mod strictly not require new difficulty attributes, but it should reuse difficulty attributes of another mod? (compare: daycore reusing difficulty attributes of half time)
  • If yes, a server-side change doing this must be made (compare: https://github.com/ppy/osu-queue-score-statistics/pull/177)
• Can the mod be described as "difficulty reduction"?
  • If mod.Type != ModType.DifficultyReduction, it must be changed to such, or this server-side check for medals must be adjusted.
  • Regardless of type, this server-side check for challenge packs must be adjusted.
