 # CHANGELOG
 
+- [2026-09-20 10:39] FEAT: v0.5 画布尺寸编辑+自动报价+扇样式保真修复——①参数化尺寸编辑: W/H输入框与拖拽外框右缘/下缘/右下角手柄, 全部几何按比例自动缩放(料宽不变,最小300mm), 拖拽静默/松手提交, 撤销栈; ②自动报价: 画布变化600ms防抖自动调offer-price并实时显示总价(样板库/订单详情); ③修复"样板显示为默认样式": 扇样式推断引擎三级解析(有效bd→polyId区域映射双扇对半→帧bbox按扇数竖向均分), 还原真实分格/开向(od角度/inward空心标记/门标注), 无图纸订单显示引导提示 (Files: frontend/src/components/WindoorCanvas.vue, frontend/src/types/drawing.ts, frontend/src/views/*, doc/API.md)
 - [2026-09-20 09:04] FEAT: v0.4 画布编辑器(拖拽布置v1)——WindoorCanvas 增加 editable 模式：＋竖梃/＋横梃点击玻璃区域实时分割(两次交叉点法多边形重算+mm.sp分割线同步)、撤销栈；订单详情可保存图纸(PUT orders)，样板库可另存我的样板(新增 POST windoor/templates is_default=0)；10接口回归全通过 (Files: frontend/src/components/WindoorCanvas.vue, frontend/src/views/*, src/huamenchuang/api/windoor.py, src/huamenchuang/schemas/windoor.py, doc/API.md)
 - [2026-09-20 09:35] FEAT: v0.3 报价算料+仓库库存+前端扩展——报价引擎(从drawing_data几何提取外框/中梃/扇框型材清单+玻璃鞋带面积,套价格本计价)；仓库模块(材料CRUD/出入库/流水/负库存拦截/预警)；前端新增仓库页与报价弹窗(样板库/订单详情可唤起)；SQLite路径锚定项目根修复cwd问题；全接口回归9/9通过 (Files: src/huamenchuang/**, frontend/**, doc/API.md)
 - [2026-09-20 09:05] FEAT: 前后端全量开发 v0.2——后端新增客户/合同(意向单→正式)/优化下料(FFD)模块与订单合同快照；前端 Vue3+Element Plus 七页面(登录/工作台/订单/合同/客户/样板库/优化下料)与自研二维窗型画布渲染器(缩放/平移/开向标记/尺寸标注)；构建产物挂载后端+SPA history 回退；全接口回归 6/6 通过 (Files: src/huamenchuang/**, frontend/**, README.md, doc/API.md)
