+## TypeScript enum 重构（全量消除 enum）
+用户决定改用纯联合类型，自行修改依赖方。全项目 18 处 enum 分两类处理：
+
+### 改为纯联合类型（字符串枚举，仅作类型用）
+- `Attachment.ts` AttachmentBizType、`Template.ts` TemplateBizType
+- `Model.ts` RunEnv / OrderType / ImageType（ImageType 值为 ir-auto 等，与 key 不同）
+- `Comment.ts` CommentReplyBizType / CommentBizType
+- `User.ts` UserAttachType（在 UserAPI.ts 有值引用，已同步改为字符串字面量，import 改 type-only）
+
+### 改为 const 对象 + 派生类型（数字枚举或运行时值引用，纯联合不可行）
+- `User.ts` LoginType、`Article.ts` ArticleType / ArticleAttachType / ArticleSoftwareDownloadType / ArticleSoftwareRuntime（数字枚举，保留数值避免破坏数据契约）
+- `deviceStore.ts` Breakpoints（数字，用于比较 width < Breakpoints.SM）
+- `IOSize.ts` Unit（用 Object.keys/values + Unit.KB 值引用）
+- `Prismjs.ts` PrismjsType / PrismjsViewer（Map 键值引用）
+- `directives/Popup.ts` PopupType（switch case 值引用）
+
+### 结论
+- `vue-tsc --noEmit` 通过（exit 0）
+- ESLint 因项目缺 eslint.config.js（仍用旧 .eslintrc，ESLint9 不支持）无法运行，属项目既有配置问题
+- 判断依据：纯联合无运行时存在，凡 `Object.keys(enum)`、`map.set(Enum.X)`、`case Enum.X`、`Enum.X` 作值的都无法纯联合，必须 const 对象
+
+## Storage.ts 设计修正
+- `getString` 返回 `string | null`（对齐 `localStorage.getItem` 契约），不再 throw
+- `getJSON` 返回 `unknown`，键不存在时返回 `null`，值无法解析时才抛错
+- `getObject` 返回 `T | null`，不再 throw（修正原 JSDoc 已写 `T | undefined` 但代码 throw 的矛盾）
+- `is` / `not` 键不存在时自然返回 `false` / `true`，不再崩
+- `has` 去掉死代码 `!== undefined`（localStorage.getItem 只返回 string|null），单次查询
+- `vue-tsc --noEmit` 通过
+
+## Toolkit.ts debounce 修复
+- **Bug 修复**：`cancel()` 原先只清定时器不重置 `leading` 状态，导致立即模式下 cancel 后首次调用丢失 leading 触发
+- **类型修复**：返回类型从 `T & { cancel(): void }` 改为 `((...args: Parameters<T>) => void) & { cancel(): void }`，防抖函数实际返回 void 而非 T 的返回值
+- 补充完整 JSDoc（含 `@example`），说明立即模式（leading + trailing）和延迟模式（trailing only）的行为差异
+- 状态变量 `immediate` → `leading`，参数 `defaultImmediate` → `immediate`，语义更清晰
+- 去掉 `eslint-disable-next-line` 和多余注释
+- `vue-tsc --noEmit` 通过
