+## BUG-274 | 个人报告中心与报告正文在移动端无法下拉
+
+- 状态：resolved（已推入 staging，待部署）
+- 首次发现：2026-08-18
+- 最近更新：2026-08-18
+- 影响面：`/reports` 个人报告中心、`/reports/[reportId]` 报告阅读容器；聊天根滚动锁不放宽。
+- 用户现象：移动端打开个人报告页后无法向下滑动阅读。
+- 触发条件：全局 `html, body { height: 100%; overflow: hidden }` 仍然锁死根滚动。报告中心只有 `min-height: 100dvh` 和 `overflow-x: hidden`，没有被视口卡住的纵向滚动容器。报告正文虽然有独立滚动层，但高度写成 `100dvh`：在移动浏览器里它可能比 `body` 的 `100%` 更高，多出来的部分被根滚动锁裁掉，容器自己却还没溢出，所以也滑不动。
+- 根因：BUG-153 只给 ready 报告加了 `100dvh + overflow-y: auto`，没有覆盖报告中心，也没有按「父级已经是 `height: 100%`」来锁高度。`overflow-x: hidden` 不会让一个随内容长高的块变成可滚动层。
+- 修复：`.report-center-shell` 与 `.personal-report-reader` 都改为 `height: 100%; overflow-y: auto`，并补上 `-webkit-overflow-scrolling: touch`。报告正文另加 `touch-action: pan-y`，避免命盘 SVG 把纵向滑动吃掉。
+- 验证：报告入口与阅读合同测试锁定两处容器都是 `height: 100% + overflow-y: auto`，且不得再写 `min-height: 100dvh` / `height: 100dvh`。
+- 防复发：任何跑在聊天根滚动锁里的独立页面，必须有「相对父级视口封顶的高度 + overflow-y: auto」。禁止只用 `min-height: 100dvh` 冒充滚动容器；也不要在 `html, body` 已是 `height: 100%` 时把子层写成未封顶的 `100dvh`。

+## BUG-275 | 后台已发布套餐无法修改，也没有删除/下架入口
+
+- 状态：resolved（已推入 staging，待部署）
+- 首次发现：2026-08-18
+- 最近更新：2026-08-18
+- 影响面：`POST /api/admin/products`、`admin_save_product_draft`、商品管理页；已有订单/订阅的硬删除限制不放宽。
+- 用户现象：编辑已发布套餐保存时返回「提交内容不符合业务约束」；列表里没有删除或下架。
+- 触发条件：对已发布种子套餐（如 `standard_monthly`）调用 `action=save` 并带上该商品 id；或在后台寻找删除按钮。
+- 根因：保存函数只更新 `status='draft'` 的行，已发布 id 会抛 `product_draft_not_found`（PostgreSQL `22023`），被统一映射成「提交内容不符合业务约束」。即便命中草稿，审计 `after_value` 仍写入禁止字段 `code`，触发 `admin_audit_logs_after_value_check`（`23514`），同样被折叠成这句话。界面把所有行都标成「编辑草稿」，也没有 delete/retire API。已发布商品因订单/订阅外键不能硬删除，正确动作是下架。
+- 修复：保存已发布/已下架商品时，复用该 code 的现有草稿或创建下一版本草稿，不再改正在售行。新增 `admin_delete_product`：草稿硬删除，已发布改为 `retired` 且 `enabled=false`。商品审计字段改为 `productCode`，避免踩兑换码审计的密钥字段禁令。管理页区分修改/发布/删除/下架，并把上述 SQL 异常映射成可读错误。
+- 验证：数据库回归用与线上失败请求同形的权益 JSON 保存已发布月卡，必须得到新草稿且原在售行不变；再次保存更新同一草稿；删除草稿后行消失；删除已发布年卡后变为下架。API/UI 合同覆盖 `action=delete`、下架文案与错误映射。
+- 防复发：后台商品写路径必须区分草稿与已发布。已发布商品的保存不得要求调用方先手建草稿；删除已发布商品只能下架，不能绕过订单/订阅外键做硬删除。`22023`/`23514` 的商品异常不得再折叠成笼统「业务约束」。写入 `audit.admin_audit_logs` 的 JSON 不得包含 `code`/`token`/`secret`/`key` 键。
