feedback5 WH: 自选 pieces in the sim — shared/diy.js (diyPool, checkDiyPick, diyRecord / diyRecordOf, validateDiyPicks: the legal picks per tier, prototypes skill-locked to their 补位 rows, owned picks any skill / module at the slot's stage, no 特质, derived bonds, one slot per owned operator, distinct picks per tier, unkitted operators refused); simdata getChess(slotId, { diy }) builds the 自选 def (diyFor, charId, loadout.diy, tokenOwner) and getToken resolves its summons from backups.json tokens; Battle, BattleSpec and the loadout view carry the PlayerBattleInput diy pick (a DIY slot without a legal pick fields nothing); kitOf takes KITS[charId] for a 自选 piece as for a stand-in; kits/index.js OPERATOR_KIT_FILES (op-<codename>.js, empty for now), GENERIC_KIT_CHARS, KITTED_CHARS; the harness fields units[].diy

No golden scenario moved (none fields a 自选 piece).
