 - 2026-07-14 BRD 发布批次复核：当前 `HEAD=1efde563` 已重新构建管理端 `assets/index-B9T505HT.js`（SHA-256 `66a827a7b3e5d794ae9da54c6e2276080995614fa52f54d49f746087663f8c94`）、`mobile-uni` H5 `assets/index-C1WoTt0t.js`（SHA-256 `bfb07609acecde3678ed18bf48ce022f36596c6b946e076436fe242cf3e15675`）和后端 `ruoyi-admin.jar`，产物时间均晚于当前提交；线上根站、`/h5/`、租户接口只读返回 `200`，线上资源仍未对齐本地。`release-preflight.sh` 因 `docs/FIGMA_DESIGN_INVENTORY.md` 与 `docs/FIGMA_DESIGN_SYSTEM_GUIDE.md` 两份用户未提交文档阻断，未执行生产静态同步、后端重启或业务数据写入；待用户完成 Figma 文档提交边界确认后再进入发布窗口。
 - 2026-07-14 BRD 验收脚本可执行性修复：`scripts/tests/demo-check-pilot-gates.test.sh` 原文件权限为 `100644`，按其 shebang 直接执行会 `permission denied`；现改为 `100755`。直接执行通过（含临时测试库行为校验），`scripts/tests/pilot-export-contract.test.mjs` 通过 `5/5`；未修改业务数据。
 - 2026-07-14 BRD 用户端回归复核：`mobile-uni` 类型检查通过，用户端单测 `53/53` 通过；源码中的“工作上报·建设中”属于 BRD 阶段二/三信息直达或北森/报事集成边界，候选人“等待后续通知”属于完成态提示，不新增一期空壳功能。测试进程曾输出既有 Vite WebSocket 端口占用警告，但测试退出码为 `0`，需在独立 CI/无并行开发服务环境再确认，不作为业务失败。
+- 2026-07-14 BRD 4.4 生产迁移顺序修复：每日三题评分模式迁移原先直接在 `score` 后添加 `score_mode`，旧生产表若缺少后来新增的 `score` 字段会迁移失败；现同一幂等脚本先补 `score`、再补 `score_mode`，并加入 `demo-check` marker。临时旧表连续执行两次迁移后得到 `score,score_mode`，未修改业务数据。
