-## 数据库迁移（alembic）

-多个 feature worktree 共用同一台 dev DB（`192.168.1.4:5433`）。任何 worktree 直接在共享库上跑迁移，都会让别的分支 `alembic upgrade` 崩（DB 里记着的 revision 在对方代码里不存在）。所以本会话：
-
- 只用 `uv run alembic revision --autogenerate -m "..."` 生成迁移文件，**绝不手写 revision 文件**。
- 生成后立即 `git add` 提交迁移文件，纳入 PR。
- **绝不**对共享 dev DB（`192.168.1.4:5433`）或 prod 执行 `alembic upgrade` / `downgrade` 等任何改库命令。
- 需要运行时验证迁移，就起一个一次性独立库（本地 docker postgres 或唯一命名的 scratch 库），在它上面 upgrade，验证完即丢弃，不要留痕。
- 共享 dev DB 与 prod 的迁移合并后由用户统一执行，时机由用户决定。

cruldra	b62e58d739	✨ feat(vscode): 新增第五种工单会话「原型会话」照测试会话那条链路补一份 prototype： - 消息与路由：session/start-prototype、session/resume-prototype、 issue/update-prototype-profile-path，都进只读门禁 - 会话：handleStartPrototypeSession / handleResumePrototypeSession，终端名 issue-N-原型；cwd 有 worktree 用 worktree、没有退主仓库根（原 resolveTestSessionCwd 改名 resolveWorktreeOrRootCwd 两种会话共用） - 不要求有 PR，任何阶段都能起；前置工单锁仍然拦 - 提示词：新增 prompts/prototype.md，设置里可改，占位符 {issueNumber} - profile：工单级 prototypeProfilePath > 设置里的原型默认 profile > 内置默认，与其它会话互不回退 - 状态字段 prototypeSessionId / prototypeProfilePath / prototypeTabOpen 贯通 gitea、youtrack、本机 state 与移交包 - 详情面板加「原型会话id」「原型配置文件」两行，设置面板加对应两项 Claude-Session: https://claude.ai/code/session_01Kgmb1LvrPmFX3NoUDB4zZC	2026-09-14 10:20:30 +08:00
