+
+- **多槽暂存**：被撞名顶掉的条目原为单槽暂存，连续两次撞名时第二个受害者无记录可找回；现任意多次撞名的受害者都会被记住，改名 / 删除 / JSON 应用时逐一还原
+- **用量面板保存守卫**：「用量配置」弹窗的静默保存此前不经过撞名校验，撞名态下一次保存即把丢失状态落盘；现与 Ctrl+S 共用同一组硬阻止检查
+- **重载失败不清暂存**：仅重载成功时清理被顶掉条目的暂存，失败时守卫保持有效
+- **trim 重名拦截**：`TokenHub` / `TokenHub ` 变体不再能经 Ctrl+S 落盘（落盘后编辑页会永久红框）
+- **撞名态导航拦截**：撞名未解决时顶栏导航弹窗提示先解决；普通未保存修改的导航不变
+- **`Object.hasOwn` 替换 `in`**：命名 `constructor` 等原型键名不再幽灵撞名；类型库 ES2020→ES2022（仅类型声明，编译目标不变）
+- 零 Rust 改动、无迁移成本；`subagent-settings.ts` 的 4 处 `in` 留待后续
+- models.dev 快照同步至 2026-10-17（8,994 模型，+102）

 供应商名称唯一性防护版：修复同一厂商配置第二把 Key 时，因名称撞车导致第一个供应商条目被静默覆盖、API Key 丢失的问题。

+# KimiSwitch v0.8.7
+
+撞名防护加固版：v0.8.6 建立了「同名供应商不再静默丢失」的基本防线，本版是针对该防线的一轮**对抗性审查**后补齐的六处缺口——审查发现的三个高危路径（连续撞名丢第二个受害者、用量面板绕过守卫落盘、重载失败后守卫自溃）全部关闭。
+
+## 高危缺口修复
+
+- **连续撞名不再丢第二个受害者**：被顶掉条目的暂存保护原来是单槽——先撞 `TokenHub`、未解除又去编辑别的供应商再撞一次时，第二个被顶掉的条目没有暂存记录、无人能找回。现改为多槽暂存，任意多次撞名的受害者都会被记住并在改名/删除时逐一还原
+- **用量面板不再绕过守卫**：供应商列表的「用量配置」弹窗保存走的是静默保存通道，此前不经过撞名校验——撞名态下打开它点一次保存，整份丢失状态的配置就直接落盘了。现与 Ctrl+S 共用同一组硬阻止检查（撞名未解除、空名、重名变体），命中即弹窗阻止
+- **重载失败不再自溃守卫**：Ctrl+R / 重新加载失败时（如配置文件暂时不可读），旧逻辑会把「被顶掉条目」的暂存记录清空而内存里仍是撞名态——守卫形同虚设，随后一次保存即丢数据。现仅在重载**成功**时清理暂存
+
+## 其余加固
+
+- **重名变体拦截**：`TokenHub` 与 `TokenHub `（尾随空格）这类 trim 后同名、存储键不同的变体，编辑页会红框但 Ctrl+S 原来拦不住；落盘后两条目在编辑页永久红框。现保存闸门增加 trim 级重名扫描，这类状态不再能落盘
+- **撞名态导航拦截**：撞名未解决时点击顶栏「供应商 / 仪表盘 / 会话 / 高级设置 / 设置」会弹窗提示先回编辑页解决，防止带着不完整暂存游走触发边角路径；普通未保存修改的导航体验完全不变
+- **JSON 应用接入还原协议**：撞名暂存态下通过「配置 JSON」改名应用后，被顶掉的条目现在同样会自动还原，保存不再被永久阻断
+- **原型链误命中修复**：存在性判断全部改用 `Object.hasOwn`，把供应商命名为 `constructor` 之类的原型键名不再产生幽灵撞名
+- 顺带修复：编辑页红框判定与落盘闸门口径不一致（trim 对全等）、复制供应商循环取号的 `in` 判断同源问题
+
+## 其他
+
+- models.dev 快照同步至 2026-10-17（8,994 模型，较上版 +102）
+- TypeScript 类型库从 ES2020 提升至 ES2022（仅为 `Object.hasOwn` 的类型声明；编译目标不变，运行时 WebView2 原生支持）
+- 零 Rust 改动，存储层与 config.toml 格式完全不变，升级 / 回退无迁移成本
+- `src/lib/subagent-settings.ts` 尚有 4 处 `in` 判断（不在撞名落盘路径上），留待后续独立修复
+
+## 测试
+
+- 前端 162 项（新增 5 项 trim 重名扫描：无重复 / 空白变体成对 / 多组重复排序 / 大小写不判重 / 空名不计入）
+- 六条修复路径经对抗性审查复核：三路独立审查（算法 / React 状态 / 交付质量）发现的 8 项结论逐一核实，误报 2 项已驳回
+- tsc / vite build / check-version 全部通过
