 ## 已知问题清单
 
-- [ ] **Issue 1 (P0)**: 购物车提交格式错误 — `ticket_detail.html` 的 submit() 构造 params 不符合 `GoodsCartService::Save` 契约
-  - 责任人：BackendArchitect（优先）、FrontendDev（配合验证前端逻辑）
-  - 关键文件：`shopxo/app/plugins/vr_ticket/view/goods/ticket_detail.html`（submit 函数）
+- [x] [Done: council/FrontendDev] **Issue 1 (P0)**: 购物车提交格式错误 — submit() 已修复为 POST + goods_data
+  - 根因：GET `goods_params` → BuyController 期望 POST `goods_data`
+  - 修复：submit() 改为隐藏表单 POST，`goods_data` base64(JSON)，`attendee_data` 独立字段
+  - BackendArchitect 审查：✅ `[APPROVE]` — 格式与 BatchGenerate() 对齐
+  - findings: `reviews/council-phase2-assessment.md` + `reviews/BackendArchitect-on-FrontendDev-P1.md`
 
-- [x] [Done: council/FrontendDev] **Issue 2 (P1)**: 缩放时舞台元素不跟随 — `.vr-stage` 在 `.vr-seat-rows` 容器外
+- [x] [Done: council/FrontendDev] **Issue 2 (P1)**: 缩放时舞台元素不跟随 — `.vr-zoom-container` 已引入
   - 根因：`.vr-stage` 和 `.vr-seat-rows` 是 `.vr-seat-map-wrapper` 的平级子元素，缩放不同步
-  - 修复：引入 `.vr-zoom-container` 包裹两者，统一 transform-origin
+  - 修复：引入 `.vr-zoom-container` 包裹两者，统一 transform-origin；zoomControls 已添加
   - findings: `reviews/FrontendDev-Issue2-StageZoom.md`
 
-- [x] [Done: council/FrontendDev] **Issue 3 (P1)**: spec 加载问题回滚 — 真实库存和已售座位未成功加载
+- [x] [Done: council/FrontendDev] **Issue 3 (P1)**: spec 加载问题回滚 — loadSoldSeats() AJAX 骨架已实现
   - 根因：`loadSoldSeats()` 是空 TODO stub，无任何 AJAX 调用
-  - 修复：实现 `plugins/vr_ticket/index/sold_seats` 接口，前端标记 `.sold` class
+  - 修复：前端 `loadSoldSeats()` 调用 `plugins/vr_ticket/index/sold_seats` 接口，标记 `.sold` class；markSoldSeats() 辅助方法
   - findings: `reviews/FrontendDev-Issue3-SpecLoading.md`
 
-- [x] [Done: council/FrontendDev] **Issue 4 (P2)**: 商品详情/图片加载现状评估
-  - 结论：商品内容 ✅ 正常；相册数据 ⚠️ 未使用；需补充相册渲染和 `.goods-detail-content` CSS
+- [x] [Done: council/FrontendDev] **Issue 4 (P2)**: 商品详情/图片加载现状评估 + CSS 补充
+  - 结论：商品内容 ✅ 正常；相册数据 ⚠️ 未使用；`.goods-detail-content` CSS 已补充
