 # CHANGELOG
 
+- [2026-09-22 00:55] FIX: v2.7 3D 开合滑杆真实按压驱动验证——el-slider 非原生 range(无 click 跳转), 改为按压手柄-移动-释放完整序列驱动; 开合两态截图对比脚本 open-compare.mjs; 滑杆 v-model 正常回写 (Files: frontend/scripts/open-compare.mjs)
 - [2026-09-22 00:30] FIX: v2.6 组合画布选中根因修复+右键菜单+3D 三场景。①选中失效根因: Vue3 布尔 prop 缺省转换(editable 缺省→false 拦截选中), withDefaults 默认 true 修复; ②右键菜单: 右键单元弹操作菜单(旋转×2/镜像/底边对齐/删除), 动作经 emit('ctx') 由父组件统一执行, document 级委托+移除 @mousedown.stop(其拦截冒泡致动作失效的行为级验证); ③3D 三场景: 室内(窗后整墙+木地板)/室外(外墙围绕+草地)/影棚(网格), 场景联动背景色, Real-browser 截图验证(旋转后 1600×1800 宽高互换✓/删除后画布清空✓/三场景渲染✓) (Files: frontend/src/components/CombineCanvas.vue, frontend/src/components/WindoorThreed.vue, frontend/src/views/CombineView.vue, frontend/scripts/verify-menu.mjs)
 - [2026-09-21 13:20] FIX: v2.5 浏览器级可视化验证与修复闭环。①新增 ui-shots.mjs/open-shot.mjs: puppeteer-core 驱动系统 Edge 无头截图+页面报错捕获(6 页面+开合状态); ②修复 watch immediate 首跑 camera 未创建(解析失败根因); ③修复 inferSashGlyphs 兜底 bboxOf 传段对象(286 个 NaN 扇矩形→0); ④profileGeo 自交轮廓重写; ⑤样板接口返回 total(修复计数 49)与前端各消费方; ⑥等高对齐落地到加入时(组合画布两单元同高底对齐); ⑦渲染页默认模式随路由+自动选中首样板+选择器回填; ⑧router 支持 token 直通(开发便捷); ⑨shadowMap.type 移除(r186); ⑩综合截图验证: 样板库/组合/3D/工作台全部正常, 无页面报错 (Files: frontend/src/**, src/huamenchuang/api/windoor.py, src/huamenchuang/scripts/seed.py, frontend/scripts/*)
 - [2026-09-21 13:05] FIX: v2.4 组合画布回归自由拖拽——移除拖动松手后的强制自动排列(其剥夺了自由摆放能力); 吸附升级为标准六边缘对齐(拖动单元左/中/右×其余单元左/中/右, 上/中/下同理, 取最近者吸附+辅助线), 允许自由重叠摆放; 自动排列保留为可选整理按钮; 参考 Konva/Fabric 吸附标准模式与掘金/CSDN 实现分析 (Files: frontend/src/components/CombineCanvas.vue, frontend/src/views/CombineView.vue)
