+# AI Policy
+
+The maintainers of this project don't want to interact directly with bots.
+Contributions must come from a human who understands the submitted code or text,
+can explain it, and is responsible for its quality as if they wrote it
+themselves. Using AI as a tool to help you write or reason about a contribution
+is fine; submitting AI output you don't understand, or relaying messages
+between a maintainer and an AI, is not.
+
+If you wish to include context from an interaction with AI in your comments, it
+must be in a quote block (e.g., using `>`) and disclosed as such. It must be
+accompanied by human commentary explaining the relevance and implications of
+the context.
+
+If you plan to contribute to termscp using AI tools, you **must** read,
+understand and follow this policy.
+
+## Disclosure
+
+You **must** disclose the use of AI tools in your contributions. You
+**must** perform this disclosure through the pull request template; filing
+PRs without using the pull request template is a violation of this policy.
+
+This applies to any AI tool that generated or substantially shaped the content
+you submit — code, prose or commit messages — including agents, chat assistants
+and AI-assisted editors. Mechanical editor autocompletion of a few characters
+does not need to be disclosed; if in doubt, disclose.
+
+## Translations
+
+AI is useful when communicating as a non-native English speaker. If you are
+using AI to edit your comments for this purpose, please take the time to ensure
+it reflects your own voice and ideas.
+
+## Provenance and licensing
+
+You are responsible for the provenance of anything you submit. AI tools can
+reproduce code or text from their training data verbatim, which may carry a
+license incompatible with this project. By contributing, you confirm the work
+is yours to submit under the project's license and does not infringe a third
+party's rights. The same standard that applies to code you write by hand.
+
+## Consequences
+
+Violating this policy may get your contribution rejected and, for repeated or
+egregious violations, get you blocked from the project without further warning.
+
+## Examples
+
+Examples of things that are not allowed:
+
+- Point an agent to a GitHub issue, ask it to solve the issue and open a PR,
+  without understanding the issue, the PR, or testing the solution yourself.
+- Copy responses from the AI when replying to questions from maintainers,
+  without understanding the question or the response.
+  In other words, you should not "play telephone" between your AI-generated code,
+  the reviewer, and the AI tool.
+
+## Inspiration
+
+This AI policy was inspired by:
+
+- [release-plz](https://github.com/release-plz/.github/blob/main/AI_POLICY.md)

 - **顶层的 Activities**：每个“视图”都是一个 Activity，并由 `Activity Manager` 来处理它们。这种方法受 Android 启发。它适用于具有不同视图的 ui，每个视图都有自己的组件和逻辑。Activities 与 `Context` 协作，`Context` 是用于在 activities 之间共享数据的数据持有者。
 - **Activities 显示 Applications**：每个 activity 可以显示不同的 **Applications**。一个 application 包含一个 **View**，它基本上是一个 **components** 列表，每个组件都有其属性。view 是组件的门面，同时也处理焦点，即当前处于活动状态的组件。你不能拥有多个活动组件，因此必须对此进行处理；与此同时，如果当前组件被销毁，焦点必须交还给之前处于活动状态的组件。**Application** 负责处理所有这些工作。要了解更多信息，请阅读 <https://github.com/veeso/tui-realm>。
-- **Components**：components 是围绕 tui 构建的，以便复用控件。这是通过 `Component` trait 实现的，该 trait 受 [React](https://reactjs.org/) 启发。每个组件都有其 *Properties*，并且可以拥有其 *States*。每个组件必须处理输入事件、接受新的属性，并提供一个用于**渲染**自身的方法。这一逻辑现在位于 [tui-realm](https://github.com/veeso/tui-realm) 中。

 - **Messages：基于 Elm 的方法**：输入事件采用受 [Elm](https://elm-lang.org/) 启发的方法来处理。在 Elm 中，你使用三个基本函数来实现 ui：**update**、**view** 和 **init**。termscp 将 Elm update 函数的等价实现编写为一个递归函数内部的大型 match 分支，你可以在每个 activity 的 `update.rs` 文件中找到它。这个 match 分支处理组件为响应传入的输入事件而产生的消息，并促使 activity 改变其状态。
 
 termscp 实现了一个名为 `Activity` 的 trait，它是 Android activity 的一个大幅精简版本。该 trait 提供以下方法：

+          collection to an absolute minimum: no tracking cookies, no advertising

+          process a limited amount of data that is technically unavoidable when
+          you visit any website — such as your IP address and server logs
+          handled by our hosting provider — together with anonymous, aggregated

+          browser, and page views). We also track a small number of anonymous
+          interaction events — for example clicks on the GitHub, crates.io, and
+          documentation links — to measure interest in the project; none of
+          these events contain personal data.
