 # CHANGELOG
 
+- [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)
 - [2026-09-20 08:14] FEAT: 订单模块 v0.1 实现与二维平面图全量采集——FastAPI 分层架构(api/services/repositories/models)、订单状态机(意向单→正式单→生产中→完工/取消)、7节点生产进度、审计日志、JWT认证、样板库API；创建契约对齐目标站{contract_id,drawing_data,pic_url}；254张样板平面图全部下载成功并静态挂载；端到端冒烟测试7/7通过 (Files: src/huamenchuang/**, pyproject.toml, README.md, doc/API.md, data/windoor-images/*, data/fetch-images.py)
