Contract 4.2.0

Badges as a player says them (Jamie, 2026-09-19: the milestone mail read 'MasterySkeletonWarriors (level 5)'; it is Guards Mastery). The API names a badge by Supercell's internal identifier and carries no display name, so every surface that says a badge now carries a label beside the identifier: elixir_timeline's badge_earned and legendary_badge_earned items gain facts.badge_label (facts.badge stays the identifier badges_holders matches on) and their text reads 'took Guards Mastery to level 5' or 'earned Beating Death'; players_profile.badges[] gains label; badges_rarity.badges[] and badges_holders gain label. Mastery badges resolve the card's internal codename to its shown name (AxeMan is Executioner, RageBarbarian is Lumberjack, SkeletonWarriors is Guards); dated badges say the month (SeasonalBadge_202509 is Season September 2025).
