 # CHANGELOG
 
+- [2026-10-05 07:30] TEST: v2.40 全量 254 套模板视觉校验——v2.39 消费路径全量回归 0 缺陷。新增两个常驻校验资产: ①frontend/scripts/verify-sash-panels.mjs(结构级: 渲染器同路径全量跑 重放/扇推断/锚点匹配/inferSashPanels, A~E 五级异常分类+子格覆盖度断言, 实测 254 文件/409 形状/570 扇/726 子格(裙板 150/格条 58) 0 异常) ②frontend/scripts/patrol-render-all.mjs(渲染级: 无头浏览器逐套切换样板真实渲染, 收集 JS 异常+画布非透明像素活性, 实测 254/254 OK 0 空白 0 异常); 6 套代表性样板视觉抽验通过(704 平开窗/31637 推拉门格条裙板/31343 双扇门裙板/31353 三扇推拉16条扇内分割/31593 平开窗/31603 四扇推拉)——v2.39 为渲染器/工具层共性修复, 全量样板自动受益, 无需逐套修改 (Files: frontend/scripts/verify-sash-panels.mjs, frontend/scripts/patrol-render-all.mjs)
 - [2026-10-05 07:14] FEAT: v2.39 渲染视觉与图纸对齐——源站原生扇内结构全量消费(扇内分割/裙板/格条/编号)。数据层诊断: 704(mm.sp=2 三区域+A1 平开扇)/31637(Frame 无分割+Slide 双推拉扇, 扇自带 mm.sp 裙板分割+mm.fls 玻璃/Panel 挂接+mm.dbs.bars decorationChinese 格条, hc=2 主格+gp=80 回纹)数据本身完整, 自研渲染器只消费顶层 mm.sp 未下钻扇内。新增 types/drawing.ts inferSashPanels(扇矩形构造临时 shape 复用 replayShape 全语义重放扇内分割, fls 按 polyId{idx,pos} 树寻址挂玻璃/裙板(type=Panel 判定), dbs.bars 格条解析 tp/gp/hc); 三渲染器消费: WindoorCanvas(2D 图纸: 裙板实色+格条内框/主格/四角回纹+玻璃编号 A1~A4)+RenderCanvas(效果图: 同语义)+WindoorThreed(3D: 裙板实体板+格条条体; 修复单 region 多扇时第二扇被 used 丢弃(改 glyph 自身矩形+共享区域保留静态底玻璃)); 扇形状按 sp 锚点归属匹配(修 sashes 数组序与视觉序交叉); WindoorCanvas 挂载加 ResizeObserver+零尺寸保护(修 el-dialog 内首帧 0 尺寸空白, 与 v2.38 3D 同型); 视觉验收: 704 渲染(开向三角/把手/编号)与 31637 四视图(双推拉+中式格条+裙板)均与官方参考图对齐; 回归: 254 套数据校验 0 失败+24 页巡检 0 异常+冒烟 60/60 (Files: frontend/src/types/drawing.ts, frontend/src/components/WindoorCanvas.vue, frontend/src/components/RenderCanvas.vue, frontend/src/components/WindoorThreed.vue)
 - [2026-10-05 06:23] FIX: v2.38 效果图页切 Tab 后 3D 展示空白修复。根因: WindoorThreed 在 /rendering 页以 v-show=false(display:none) 挂载, 容器 clientWidth=0 时 Three.js 以 0 尺寸初始化(camera.aspect=0/0=NaN), 页内切 Tab 显示后仅 window resize 事件无法触发重设尺寸→画布永远空白(直接访问 /threed 路由正常, 故 24 页巡检未覆盖); 修复: onResize 加零尺寸保护(避免 NaN 投影矩阵)+ResizeObserver 监听容器(显示瞬间尺寸 0→正常自动恢复)+初始 setSize 兜底 ||1; 无头复验 /rendering 切 Tab 场景渲染正常; 巡检 24 页 0 异常 (Files: frontend/src/components/WindoorThreed.vue)
 - [2026-10-05 06:11] FIX: v2.37 效果图渲染歪斜线修复——Canvas stroke 落错路径。根因: 玻璃多边形 fill 后叠加高光四边形(beginPath 新路径), 其后 ctx.stroke() 描的是最后构建的高光斜四边形而非玻璃多边形, 型材线全部变成斜线; 同型缺陷 3 处一并修复: RenderCanvas.vue(效果图渲染, stroke 移至高光前)+variantRenderer.ts renderAI(AI 炫图本地渲染, restore 后重建玻璃多边形路径再 stroke)+photoCompose.ts(照片式 AI 合成, 同 RenderCanvas 改法); 排查方法: 无头浏览器 hook moveTo/lineTo/beginPath 还原绘制序列, 证实矩形区域路径全部轴对齐、歪线恰为 3 个高光平行四边形; 高光斜带本为设计效果(clip 玻璃内)保留不变; 巡检 24 页 0 异常 (Files: frontend/src/components/RenderCanvas.vue, frontend/src/components/variantRenderer.ts, frontend/src/components/photoCompose.ts)
