**Branch/Commit:**

main

**Describe the feature:**

Please include a detailed description of the feature you are requesting and any detail on it’s expected behavior.

> **As a user**
> **I add a project that I which to use as some sort of template project**
> **And then I add all the stories with descriptions**
> **I don't want anyone to accidentally delete the template project (since it cannot be recovered)**
> **I don't want anyone to accidentally delete a story in my template project (since it cannot be recovered**

**Problem:**

Please include a detailed description of the problem this feature would solve.

> **As a user**
> **I add a project with stories**
> **So that I can use the project as a template to be cloned for future projects**
> **Now I or anybody on my team can delete the project**
> **And I or anybody on my team can delete stories in the project**
> **There is no way to prevent projects or stories from being deleted**
> **There is no way to recover a project or story after it has been deleted**

**Ideas:**

I see two possible solutions, we can discuss implementing either or both.

1. A permission scheme that prevents unauthorised deletion.
2. Prevent deleting all together, use a different mechanism such as archiving or rejecting
3. Allow soft deleting only so we can recover projects and stories.

该 issue 没有提到任何文件、测试或入口点。首先确定项目需要删除权限、归档、软删除，还是这些方式的组合，然后跟踪现有的项目和故事删除流程。当所选方案能够防止或恢复误删除，并且已针对项目和故事两者完成验证时，即视为完成。
