 - 回归结果维持API 581项、前端45项通过，测试用例见 `TC-PORTAL-001..010`。浏览器插件在网络恢复后仍多次导航、截图及DOM读取超时，真实页面视觉效果、浏览器控制台及登录后交互验收尚未完成，留待用户在测试环境验收，不标记为已通过。
 - 证据：服务器 `/tmp/cmpp-sixfix-deploy.log`、`/tmp/cmpp-sixfix-before.json`、`/tmp/cmpp-sixfix-after.json` 及恢复点清单。提交时仅纳入本轮代码/用例/进度追加，原有4份修改文档及3项未跟踪文件仍保留为未提交状态。

+## 2026-08-31 迁移后预生产六项修复发布准备
+
+- 用户明确授权推送最新代码并发布预生产，提醒数据迁移已完成。重新读取迁移记录及线上事实：预生产业务标记仍为 `1a5063a`，三项存储分别绑定到 `/data/postgresql`、`/data/redis`、`/data/minio`，数据盘UUID为 `ef4ee3bb-a19b-4aeb-b00c-aa2b995611c2`，备份入口解析到 `/data/cmpp-platform-backups`；12项服务active，三条Stream pending/lag为0。
+- 三份尚未提交的迁移保护脚本与线上LF归一化SHA逐项一致，本轮仅接续提交 `production-bootstrap.sh`、`production-deploy.sh`、`check-data-storage.sh`，其余原有修改及未跟踪文档保持不动。补充部署契约及 `TC-STORAGE-DEPLOY-001/002`，隔离mount namespace中隐藏Redis绑定后两入口前置部分均拒绝继续，宿主挂载与存储PID不变。
+- 本次发布只切换应用代码和相关监控规则，不重新迁移/恢复数据库，不重启PostgreSQL、Redis或MinIO，不改fstab、存储保护、环境及业务配置。首份新恢复资产因Redis配置路径错误在tar阶段中止，未部署；核实 `/etc/redis/redis.conf` 后重新建立完整资产，最终证据另记。
