卡⑤T1-T3(迭代47·Esc浮窗与营地顶栏批): Esc浮窗三钮+MainEscFlow四态路由+CampHudBand顶栏栏+设置语境分支+断言批——终态六枚落满

- 三新件: camp_esc_overlay(modal_shell+三钮,退出=danger_button,零动效零新素材)/main_esc_flow(静态承接件零成员态:is_camp_context+on_esc_input四态路由+_other_modal_open登记册集合查询+三出口动线)/camp_hud_band(48px浮层+keystone_badge,refresh_camp=bus目标册契约面)
- 接线: ui_registry contract+node()第六槽(营地层与设置层之间——契约3栈语义正解);ui_camp_modals六枚落满(卡⑥终态);main_ui_build实例化+三出口薄委托接线+bus目标册纳入HUD栏;main.gd _unhandled_input(契约9接线定稿:KEY_ESCAPE配physical/pressed非echo/禁轮询/不挂ui_cancel)+三薄委托零新增成员;presenter.open_camp尾挂刷新单口(契约5时机②);main_overlay_flow._on_settings_closed语境分支(谓词=esc_overlay.visible谁开谁收)
- 契约9分支序修正: ①先于②(设置开在浮窗之上态先命中无反馈——浮窗不隔层关闭;首装②先被实机场景证伪,孤检2红溯源后按卡面编号归位)
- 断言批: screen_flow Esc步十断言(根态唤起/再按关窗/echo零响应/子界面无反馈/HUD直写显式触发9999/设置开态不误关/关设置回浮窗/返回动线四可见性/菜单语境不唤起)+ui_struct浮窗段(三钮仅三/零动效双件源码+子树AnimPlayer=0/debug_badge零波及)
- 验证: 冒烟PASS+system_test 69项0失败+七探针全绿(screen_flow/ui_struct含Esc段/ui_click问题=0/ui_probe/ui_contrast36对/shot);S9/S10/S13归基线
