feedback7 UIBACK: 准备就绪 folds the shop bar and cancelling the ready unfolds it again (GitHub #138 by blackyang40-cmd; the owner's decision of 2026-10-07 — dragging an operator by its body is not part of it): gameLogic readyShopFold over the confirmed m.private.ready, only a change inside one prep round counts (not a reconnect's first state, the new round's reset, a phase outside the prep); the enemy pen keeps the state it returns to; test/ui/ready-fold.test.js + ready-fold.e2e.test.js; golden: unchanged (client only)
