+# csc 项目 UI 文案可直接替换清单
+
+- 目的：筛选出**只需要替换展示文案**、即可让 UI 页面显示 `CoStrict` 而不是 `Claude` / `Claude Code` / `Anthropic` 的内容。
+- 筛选原则：
+  1. 仅保留用户可见文案，例如 `title`、`subtitle`、`message`、`placeholder`、`label`、`aria-label`、`<Text>` 文本。
+  2. 不纳入命令、包名、环境变量、URL、路径、主题 token、埋点名、注释说明。
+  3. 对账号体系、订阅体系、Desktop/Chrome 集成等文案，标记为“**可替换但需谨慎**”。
+
+---
+
+## 一、高置信：可直接文本替换的 UI 文案
+
+这部分基本都属于纯展示文本，直接替换后主要影响界面显示，不会直接触发命令、配置或协议变更。
+
