feedback5 WK: the 集成战略 (ISW-A) module rule is a roster rule — validateDiyPicks (so room.diy, PlayerState.setDiy and the picker) refuses it, checkDiyPick / diyRecordOf / the sim still compose any module of the form (the kits' tests and the golden diy family field them); shared/diy.js diyModuleOf; docs follow

Golden unchanged.
