// Community report of 2026-10-06 「凯瑟琳装备池没有超出商店等级的装备，原版凯瑟琳1升2都能有6本装备」 (item 43): the 凯瑟琳 strategy
// (定向投放, up_shop_add_special_goods {count 3, choice 1, pool pool_equip_kathe}) offered only items up to the shop level —
// data/choices.json pool_equip_kathe maxTier 'shopLevel', an [ASSUMED] cap (the pool is server-side). The players' first-hand
// account: tier VI items show at the 1 → 2 upgrade. The pool is every shop-eligible item now (uniform [ASSUMED]).
