feedback1 WB: bounty drafts offer the cards of their half (late bounty enemies no longer in the R3 draft)

Player report #2: boss bounties, second-half specials and their upgraded copies
showed up in the first 悬赏决策 draft. A draft up to R7 (the official wave
generator's first half) now offers the 接下来两场作战 cards, a draft from R8 the
下场作战 and multi-round cards, with no tier window (the official late draft
screenshot shows boss bounties worth 1 to 6 together). choices.json cards.bounty
draftHalf, schedule bountyHalf; the mode's inactive enemy list no longer thins
the bounty draft (PRTS 11/18 note).

+ * 险境 co-op R3 / R6), 2 = the drafts from R8 on (R9). The official card list of each draft event (enemy_initial_1..10,
+ * bounty_hunter_1..15, bossInitial_1..6) is server-side; what the official side shows:
+ *   - the one official co-op 悬赏决策 screenshot (Bahamut 12294, research 06 §15 "Wrkhtxv") holds six boss bounties —
+ *     “复仇者” 6, “庞贝” 2, W 1, 萨卡兹百夫长 2, “邪魔的利刃” 3, 碎骨 1 — with the team at LP 6 / 10 / 9 / 15: a late
+ *     draft, coin values 1–6 together;
+ *   - the data's six faction series pair the battles with the wave generator's halves (specialEnemyInfoDict
+ *     isInFirstHalf): "接下来两场作战" (_4–_6) bring first-half enemies or their attached keys (妖怪, 磨砻, 逐腐兽, 萨卡兹
+ *     枯朽战车, 山海众头目, 深池伙友卫队 …), "下场作战" (_7 / _8) second-half specials or their upgraded copies (法术大师A2,
+ *     假想敌：蚀裂, 尖端萨卡兹枯朽战车, 新硎, 家族暗影灭迹人, 异光体孽生者 …).
+ * Rule: a "接下来两场作战" card (data `round` 2) is a first-half card; a "下场作战" card (the boss bounties, the 特异 giants,
+ * the faction _7 / _8 cards, 源石虫·特训) and a multi-round card (the 假想敌, a second-half special each) a second-half
+ * one [ASSUMED beyond the evidence above]. Not a drafted card ⇒ null.
