feedback5 WE: the 整备区 rules of PRTS 卫戍协议/帮助 §手牌区 (GitHub #82, second part) — a full regular hand refuses every purchase and reward pick, also one whose copy would complete a merge at once ("当常规手牌区全满无空位时，玩家将无法执行使手牌溢出的操作" — "例如招募/购入等通常情况下会增加手牌的操作"; BWIKI 盟约 says the same with no exception; the reporter checked it in the official game), and a free regular slot pulls the 临时整备区 in at once ("常规手牌区出现空位时自动移入"): PlayerState._fillHandFromTemp runs in every recompute, the temp row right to left (the order it fills, [ASSUMED]) into the hand's free slots right to left — after a sale, a deployment from the hand, a merge that consumed hand copies, an item equipped / destroyed / used, a summon stack removed with its owner. invariants.js: temp holds pieces only while the hand is full. The client's refusal path follows (gameLogic.shopBlockReason: 整备区已满 on every card — a one-line change in a file the R5 split moves). Bots: a full hand never tries a purchase, an affordable third copy of a held pair sheds the weakest hand single first (never one of this prep), resolveTemp decides temp right to left. Tests: test/match/feedback5-hand.test.js; merge / hardening / playtest6-elite-to-board / economy / prep-bench / uiFixes updated to the rule. Docs: META §1 Hand, DESIGN §6, PLAYING §3, research 00-INDEX / 01 (the old "a merge-completing purchase is allowed" corrected). Golden: 3 match scenarios moved (coop2-NORMAL-3, solo-HARD-9-boosted, coop2-ABYSS-10-boosted — bot seats that reached a full hand: the merge-completing purchase refused or a single shed first, temp pieces moving in by themselves); every battle digest unchanged
