+## Verification
+- [x] Directories created: default/, zh-CN/, ja-JP/, en-US/
+- [x] Files created: common.json, domain.json, settings.json, errors.json
+- [x] Each file has >5 translation keys (minimum 20 per file)
+- [x] Flat key structure used (no nested objects)
+
+## Sample Content
+
+### common.json (default)
+```json
+{
+  "appName": "Kintone Manager",
+  "save": "保存",
+  "cancel": "取消",
+  "delete": "删除",
+  "edit": "编辑",
+  ...
+}
+```
+
+### domain.json (default)
+```json
+{
+  "title": "域名管理",
+  "addDomain": "添加域名",
+  "editDomain": "编辑域名",
+  ...
+}
+```
+
+### settings.json (default)
+```json
+{
+  "title": "设置",
+  "language": "语言",
+  "selectLanguage": "选择语言",
+  ...
+}
+```
+
+### errors.json (default)
+```json
+{
+  "networkError": "网络错误",
+  "invalidDomain": "无效的域名",
+  "connectionFailed": "连接失败",
+  ...
+}
+```
+
+## Notes
+- Structure was already in place from prior work
+- All translations follow flat key structure
+- Chinese is the default/source language
+- English and Japanese translations provided

+# Task 04: Locale Store - Compilation Evidence
+
+## Date: 2026-03-13
+
+## Files Created
+- src/renderer/src/stores/localeStore.ts
+
+## Verification
+
+### TypeScript Check
+```bash
+npx tsc --noEmit
+# Result: PASSED (no errors)
+```
+
+### Store Implementation
+- Uses Zustand with persist middleware
+- Imports LocaleCode and DEFAULT_LOCALE from @shared/types/locale
+- Persists only the locale state value (partialize pattern)
+- Exports useLocaleStore hook
+
+### State Shape
+```typescript
+interface LocaleState {
+  locale: LocaleCode;          // "zh-CN" | "ja-JP" | "en-US"
+  setLocale: (locale: LocaleCode) => void;
+}
+```
+
+### Default Value
+- locale: "zh-CN" (from DEFAULT_LOCALE constant)
+
+## Status: COMPLETED

+# Task 06: Configure @lobehub/i18n-cli
+
+## Completed Actions
+
+1. **Installed @lobehub/i18n-cli@^1.26.1** as dev dependency
+2. **Added npm script**: `"i18n": "lobe-i18n"` to package.json
+3. **Verified CLI works**: `npm run i18n -- --help` returns usage info
+
+## Existing Configuration (.i18nrc.js)
+
+```javascript
+module.exports = {
+  entry: ['src/renderer/src/locales/default/*.json'],
+  output: 'src/renderer/src/locales',
+  entryLocale: 'zh-CN',
+  outputLocales: ['en-US', 'ja-JP'],
+  apiKey: process.env.OPENAI_API_KEY || '',
+  apiModel: 'gpt-4o-mini',
+};
+```
+
+## CLI Usage
+
+```bash
+# Run translation
+npm run i18n
+
+# With markdown translation
+npm run i18n -- --with-md
+
+# Lint translations
+npm run i18n -- --lint
+```
+
+## Notes
+
+- Source locale: zh-CN (in `locales/default/`)
+- Output locales: en-US, ja-JP
+- API key must be set via `OPENAI_API_KEY` environment variable
+- Uses gpt-4o-mini model for translation
