+### Encoding Detection

+- **`src/utils/encoding.ts`** — 文件编码检测的唯一入口。提供 `detectEncoding`（三层检测：BOM → UTF-8 fatal → ICU 回退链）和 `decodeBuffer`/`encodeString` 函数。检测基于文件头部 4KB，零外部依赖，仅使用 TextDecoder API。ISO-8859-1 作为最终兜底编码（单字节编码永远成功）。`FileEncoding` 类型扩展了 `BufferEncoding`，覆盖 gbk/gb18030/shift_jis/euc-kr/euc-jp/big5/iso-8859-1。
+- `fs.readFileSync(path, { encoding })` 的 `encoding` 选项只接受 `BufferEncoding`，不支持 `gbk`/`shift_jis` 等 ICU 编码名。读取非 UTF-8 文件时必须先 `fs.readFileSync(path)` 读 Buffer，再用 `TextDecoder` 解码。项目中所有文件读取路径（fileRead.ts、fileReadCache.ts、file.ts）已统一使用 `decodeBuffer` 函数处理此逻辑。

+# `/autofix-pr` 命令实现规格文档
+
+> **状态**：规划阶段（2026-04-29），等待评审通过后进入实施。
+> **Worktree**：`E:\Source_code\Claude-code-bast-autofix-pr`，分支 `feat/autofix-pr`，基于 `origin/main` 4f1649e2。
+> **架构**：R（Remote-via-CCR），完整版（含 stop 子命令、单例锁、subscribePR、in-process teammate、skills 探测）。
+
+---
+
+## 一、背景
+
+### 1.1 问题
+
+本仓库（`Claude-code-bast`）是 Anthropic 官方 `@anthropic-ai/claude-code` 的反编译/重构版本。许多远程能力被 stub 化处理 —— `/autofix-pr` 是其中之一：
+
+```js
+// src/commands/autofix-pr/index.js（当前 stub）
+export default { isEnabled: () => false, isHidden: true, name: 'stub' };
+```
+
+三个字段共同导致命令在斜杠菜单中完全不可见、不可调起：
+
+| 字段 | 值 | 效果 |
+|---|---|---|
+| `isEnabled` | `() => false` | 注册时被判定不可用 |
+| `isHidden` | `true` | 即使被列出也被过滤 |
+| `name` | `'stub'` | 实际注册名是 `'stub'`，输入 `/autofix-pr` 无法匹配 |
+
+### 1.2 用户场景
+
+用户在 fork 仓库（`feat/autonomy-lifecycle-upstream` 分支）尝试对上游 `claude-code-best/claude-code#386` 跑 `/autofix-pr 386`，多次报 `git_repository source setup error`。根因：官方派发的远程 session 落在被 MCP 拒绝访问的仓库（`amdosion/claude-code-bast`），权限/可见性问题。
+
+### 1.3 目标
+
+| ID | 需求 | 验收 |
+|---|---|---|
+| R1 | 命令在斜杠菜单可见可调起 | 输入 `/au` 出现补全 |
+| R2 | 跨仓库 PR：从本地 fork 触发对上游 PR 的修复 | `/autofix-pr 386` 不报 repo-not-allowed |
+| R3 | 远端真正完成修复并 push 回 PR 分支 | PR 出现来自远端的新 commit |
+| R4 | 不破坏现存其他 stub（如 `share`） | 只动 `autofix-pr` |
+| R5 | TypeScript 严格模式，`bun run typecheck` 零错误 | CI 绿 |
+| R6 | bridge 可触发（Remote Control 场景） | `bridgeSafe: true` 生效 |
+| R7 | 支持 stop/off 子命令 | `/autofix-pr stop` 能终止当前监控 |
+| R8 | 单例锁防止重复派发 | 已监控 PR 时拒绝新启动并提示 |
+
+---
+
+## 二、反编译调研结论（来源：`C:\Users\12180\.local\bin\claude.exe`）
+
+`claude.exe` 是 242MB 的 Bun 原生编译产物（JS 源码 embed 在二进制内）。通过对该文件的字符串提取（`grep -aoE`）反推出完整调用链。
+
+### 2.1 主入口函数结构
+
+```js
+async function entry(input, q, ctx) {
+  const isStop = input === "stop" || input === "off"
+  const args = { freeformPrompt: input }
+  return main(args, q, ctx)
+}
+
+async function main(args, q, { signal, onProgress }) {
+  // args 字段：{ prNumber, target, freeformPrompt, repoPath, skills }
+  d("tengu_autofix_pr_started", {
+    action: "start",
+    has_pr_number: String(args.prNumber !== undefined),
+    has_repo_path: String(args.repoPath !== undefined),
+  })
+  // ...
+}
+```
+
+### 2.2 `teleportToRemote` 调用签名（黄金证据）
+
+```ts
+const session = await teleportToRemote({
+  initialMessage: C,                       // 给远端的初始消息
+  source: "autofix_pr",                    // ⚠️ 新字段，本仓库 teleport.tsx 没有
+  branchName: N,                           // PR 头分支
+  reuseOutcomeBranch: N,                   // 与 branchName 同 — 远端 push 回原分支
+  title: `Autofix PR: ${owner}/${repo}#${prNumber} (${branch})`,
+  useDefaultEnvironment: true,             // ⚠️ 不用 synthetic env（与 ultrareview 不同）
+  signal,
+  githubPr: { owner, repo, number },
+  cwd: repoPath,
+  onBundleFail: (msg) => { /* ... */ },
+})
+```
+
+**与 `ultrareview` 的关键差异**：
+
+| 字段 | ultrareview | autofix-pr |
+|---|---|---|
+| `environmentId` | `env_011111111111111111111113`（synthetic） | 不传 |
+| `useDefaultEnvironment` | 不传 | `true` |
+| `useBundle` | 有（branch mode） | 不传（`skipBundle` 隐含于不传 bundle） |
+| `reuseOutcomeBranch` | 不传 | 传（远端 push 回原 PR 分支） |
+| `githubPr` | 不传 | 必传 |
+| `source` | 不传 | `"autofix_pr"` |
+| `environmentVariables` | `BUGHUNTER_*` 一堆 | 不传 |
+
+### 2.3 `registerRemoteAgentTask` 调用
+
+```ts
+registerRemoteAgentTask({
+  remoteTaskType: "autofix-pr",
+  session: { id: session.id, title: session.title },
+  command,
+  isLongRunning: true,        // poll 不消费 result，靠通知周期驱动
+})
+```
+
+### 2.4 子命令解析
+
+```
+/autofix-pr <PR#>                    → 启动监控 + 派 CCR session
+/autofix-pr stop                     → 停止当前监控
+/autofix-pr off                      → 同 stop
+/autofix-pr <freeform-prompt>        → 自由 prompt 模式（无 PR 号）
+/autofix-pr <owner>/<repo>#<n>       → 跨仓库（覆盖 R2 验收）
+```
+
+### 2.5 状态模型
+
+- **单例锁**：同一时刻只能监控一个 PR。重复启动报：`already monitoring ${repo}#${prNumber}. Run /autofix-pr stop first.`（error_code: `rc_already_monitoring_other`）
+- **PR 订阅**：调 `kairos.subscribePR(owner, repo, taskId)` —— 依赖 `KAIROS_GITHUB_WEBHOOKS` feature flag（用户已订阅，可用）
+- **in-process teammate**：注册后台 agent
+  ```ts
+  const teammate = {
+    agentId,
+    agentName: "autofix-pr",
+    teamName: "_autofix",
+    color: undefined,
+    planModeRequired: false,
+    parentSessionId,
+  }
+  ```
+- **Skills 探测**：扫项目里 autofix-related skills（如 `.claude/skills/autofix-*` 或根目录 `AUTOFIX.md`），命中后拼到 prompt：`Run X and Y for custom instructions on how to autofix.`
+
+### 2.6 Telemetry
+
+| 事件 | 字段 |
+|---|---|
+| `tengu_autofix_pr_started` | `{ action, has_pr_number, has_repo_path }` |
+| `tengu_autofix_pr_result` | `{ result, error_code? }` |
+
+`result` 取值：`success_rc` / `failed` / `cancelled`
+
+`error_code` 取值：
+
+| code | 含义 |
+|---|---|
+| `rc_already_monitoring_other` | 已在监控其他 PR |
+| `session_create_failed` | teleport 失败 |
+| `exception` | 未捕获异常 |
+
+### 2.7 错误返回结构
+
+```ts
+function errorResult(message: string, code: string) {
+  d("tengu_autofix_pr_result", { result: "failed", error_code: code })
+  return {
+    kind: "error",
+    message: `Autofix PR failed: ${message}`,
+    code,
+  }
+}
+
+function cancelledResult() {
+  d("tengu_autofix_pr_result", { result: "cancelled" })

+
+下表列出实现 `/autofix-pr` 时**直接复用**的现成能力（已确认完整可用）：
+
+| 能力 | 文件 | 角色 |
+|---|---|---|
+| `teleportToRemote` | `src/utils/teleport.tsx:947` | 派 CCR 远端 session（缺 `source` 字段，需补） |
+| `registerRemoteAgentTask` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx:526` | 注册 long-running 任务到 store |
+| `checkRemoteAgentEligibility` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx:185` | 前置鉴权检查 |
+| `getRemoteTaskSessionUrl` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx` | 生成 session 跟踪 URL |
+| `formatPreconditionError` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx` | 错误文案格式化 |
+| `REMOTE_TASK_TYPES` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx:103` | 已含 `'autofix-pr'` 类型 |
+| `AutofixPrRemoteTaskMetadata` | `src/tasks/RemoteAgentTask/RemoteAgentTask.tsx:112` | `{ owner, repo, prNumber }` schema |
+| `RemoteSessionProgress` | `src/components/tasks/RemoteSessionProgress.tsx` | 进度面板 UI（已认 autofix-pr 类型） |
+| `detectCurrentRepositoryWithHost` | `src/utils/detectRepository.ts` | 解析 owner/repo |
+| `getDefaultBranch` / `gitExe` | `src/utils/git.ts` | git 工具 |
+| `feature('FLAG')` | `bun:bundle` | feature flag 系统（CLAUDE.md 红线：只能在 if/三元条件位置直接调用） |
+
+### 模板答案文件
+
+以下三个文件已确认完整工作，是本次实现的"参考答案"：
+
+- `src/commands/review/reviewRemote.ts`（317 行）—— **主模板**，照抄改造
+- `src/commands/ultraplan.tsx`（525 行）
+- `src/commands/review/ultrareviewCommand.tsx`（89 行）
+
+---
+
+## 四、命令对象规格
+
+### 4.1 `Command` 类型选择
+
+`Command` 类型定义在 `src/types/command.ts`，三态之一：`PromptCommand` / `LocalCommand` / `LocalJSXCommand`。
+
+**选 `LocalJSXCommand`**，因为：
+- 需要 spawn 远端 session 并显示进度面板
+- 兄弟命令 `ultraplan` / `ultrareview` 都用 local-jsx
+- 接口签名：`call(onDone, context, args) => Promise<React.ReactNode>`
+
+### 4.2 `index.ts` 完整形状
+
+```ts
+import { feature } from 'bun:bundle'
+import type { Command } from '../../types/command.js'
+
+const autofixPr: Command = {
+  type: 'local-jsx',
+  name: 'autofix-pr',                          // 关键：必须是 'autofix-pr' 不是 'stub'
+  description: 'Auto-fix CI failures on a pull request',
+  argumentHint: '<pr-number> | stop | <owner>/<repo>#<n>',
+  isEnabled: () => feature('AUTOFIX_PR'),
+  isHidden: false,
+  bridgeSafe: true,
+  getBridgeInvocationError: (args) => {
+    const trimmed = args.trim()
+    if (!trimmed) return 'PR number required, e.g. /autofix-pr 386'
+    if (trimmed === 'stop' || trimmed === 'off') return undefined
+    if (/^\d+$/.test(trimmed)) return undefined
+    if (/^[\w.-]+\/[\w.-]+#\d+$/.test(trimmed)) return undefined
+    return 'Invalid args. Use /autofix-pr <pr-number> | stop | <owner>/<repo>#<n>'
+  },
+  load: async () => {
+    const m = await import('./launchAutofixPr.js')
+    return { call: m.callAutofixPr }
+  },
+}
+
+export default autofixPr
+```
+
+### 4.3 参数解析规则
+
+```
+^stop$ | ^off$            → { action: 'stop' }
+^\d+$                     → { action: 'start', prNumber, owner: <git>, repo: <git> }
+^([\w.-]+)/([\w.-]+)#(\d+)$ → { action: 'start', prNumber, owner, repo }
+其他                       → { action: 'start', freeformPrompt: <input> }
+空字符串                   → 错误
+```
+
+---
+
+## 五、文件结构
+
+```
+src/commands/autofix-pr/
+├── index.ts                       # 命令对象（替换 index.js）
+├── launchAutofixPr.ts             # 主流程
+├── parseArgs.ts                   # 参数解析（独立便于测试）
+├── monitorState.ts                # 单例锁
+├── inProcessAgent.ts              # 后台 teammate
+├── skillDetect.ts                 # 项目 skills 探测
+└── __tests__/
+    ├── parseArgs.test.ts
+    ├── monitorState.test.ts
+    ├── launchAutofixPr.test.ts
+    └── index.test.ts              # bridge invocation error 测试
+```
+
+**删除**：原 `index.js`、`index.d.ts`（合并进 `index.ts`）。
+
+**修改**：
+- `scripts/defines.ts` —— 加 `AUTOFIX_PR` flag
+- `scripts/dev.ts` —— dev 默认开启
+- `src/utils/teleport.tsx` —— `teleportToRemote` 选项加 `source?: string` 字段并透传
+- `src/commands.ts` —— **不动**（import 路径 `'./commands/autofix-pr/index.js'` 在 ESM/Bun 下会自动解析到 `.ts`）
+
+---
+
+## 六、模块详细规格
+
+### 6.1 `parseArgs.ts`
+
+```ts
+export type ParsedArgs =
+  | { action: 'stop' }
+  | { action: 'start'; prNumber: number; owner?: string; repo?: string }
+  | { action: 'freeform'; prompt: string }
+  | { action: 'invalid'; reason: string }
+
+export function parseAutofixArgs(raw: string): ParsedArgs {
+  const trimmed = raw.trim()
+  if (!trimmed) return { action: 'invalid', reason: 'empty' }
+  if (trimmed === 'stop' || trimmed === 'off') return { action: 'stop' }
+  if (/^\d+$/.test(trimmed)) {
+    return { action: 'start', prNumber: parseInt(trimmed, 10) }
+  }
+  const cross = trimmed.match(/^([\w.-]+)\/([\w.-]+)#(\d+)$/)
+  if (cross) {
+    return {
+      action: 'start',
+      owner: cross[1],
+      repo: cross[2],
+      prNumber: parseInt(cross[3], 10),
+    }
+  }
+  return { action: 'freeform', prompt: trimmed }
+}
+```
+
+### 6.2 `monitorState.ts`
+
+```ts
+import type { UUID } from 'crypto'
+
+type MonitorState = {
+  taskId: UUID
+  owner: string
+  repo: string
+  prNumber: number
+  abortController: AbortController
+  startedAt: number
+}
+
+let active: MonitorState | null = null
+
+export function getActiveMonitor(): Readonly<MonitorState> | null {
+  return active
+}
+
+export function setActiveMonitor(state: MonitorState): void {
+  if (active) throw new Error(`Monitor already active: ${active.repo}#${active.prNumber}`)
+  active = state
+}
+
+export function clearActiveMonitor(): void {
+  if (active) {
+    active.abortController.abort()
+    active = null
+  }
+}
+
+export function isMonitoring(owner: string, repo: string, prNumber: number): boolean {
+  return active?.owner === owner && active?.repo === repo && active?.prNumber === prNumber
+}
+```
+
+### 6.3 `inProcessAgent.ts`
+
+仿官方 `xd9` 函数：
+
+```ts
+import { randomUUID, type UUID } from 'crypto'
+import { getCurrentSessionId } from '../../bootstrap/state.js'
+
+export type AutofixTeammate = {
+  agentId: UUID
+  agentName: 'autofix-pr'
+  teamName: '_autofix'
+  color: undefined
+  planModeRequired: false
+  parentSessionId: UUID
+  abortController: AbortController
+  taskId: UUID
+}
+
+export function createAutofixTeammate(
+  initialMessage: string,
+  target: string,
+): AutofixTeammate {
+  return {
+    agentId: randomUUID(),
+    agentName: 'autofix-pr',
+    teamName: '_autofix',
+    color: undefined,
+    planModeRequired: false,
+    parentSessionId: getCurrentSessionId(),
+    abortController: new AbortController(),
+    taskId: randomUUID(),
+  }
+}
+```
+
+### 6.4 `skillDetect.ts`
+
+```ts
+import { existsSync } from 'fs'
+import { join } from 'path'
+
+export function detectAutofixSkills(cwd: string): string[] {
+  const candidates = [
+    'AUTOFIX.md',
+    '.claude/skills/autofix.md',
+    '.claude/skills/autofix-pr/SKILL.md',
+  ]
+  return candidates.filter(rel => existsSync(join(cwd, rel)))
+}
+
+export function formatSkillsHint(skills: string[]): string {
+  if (skills.length === 0) return ''
+  return ` Run ${skills.join(' and ')} for custom instructions on how to autofix.`
+}
+```
+
+### 6.5 `launchAutofixPr.ts`
+
+主流程伪代码（约 250 行）：
+
+```ts
+import type { LocalJSXCommandCall } from '../../types/command.js'
+import { parseAutofixArgs } from './parseArgs.js'
+import { getActiveMonitor, setActiveMonitor, clearActiveMonitor, isMonitoring } from './monitorState.js'

+}
+```
+
+> **注意**：`feature('KAIROS_GITHUB_WEBHOOKS')` 必须直接放在 if 条件位置，不能赋值给变量（CLAUDE.md 红线）。
+
+### 6.6 `teleport.tsx` 补 `source` 字段
+
+```diff
+ export async function teleportToRemote(options: {
+   initialMessage: string | null
+   branchName?: string
+   title?: string
+   description?: string
++  /**
++   * Identifies which command/flow originated this teleport. CCR backend
++   * uses this for routing/billing/observability. Known values: 'autofix_pr',
++   * 'ultrareview', 'ultraplan'. Pass-through field — not interpreted client-side.
++   */
++  source?: string
+   model?: string
+   permissionMode?: PermissionMode
+   // ...
+ })
+```
+
+并在内部构造 request 时透传到 session_context（具体字段名按现有 review/ultraplan 调用结构对齐）。
+
+---
+
+## 七、Feature Flag
+
+### 7.1 新增 flag
+
+`scripts/defines.ts` 已有的 flag 集合中加 `AUTOFIX_PR`。
+
+### 7.2 启用矩阵
+
+| 环境 | 是否默认开启 | 说明 |
+|---|---|---|
+| dev (`bun run dev`) | 是 | `scripts/dev.ts` 加进默认列表 |
+| build (production `bun run build`) | 否 | 灰度上线，需要 `FEATURE_AUTOFIX_PR=1` 显式开启 |
+| 测试 | 按需 | 测试文件通过 mock `bun:bundle` 控制 |
+
+### 7.3 与官方上游同步策略
+
+如果上游某天恢复官方实现，本仓库的本地实现优先（项目即 fork）：
+1. 保留 `AUTOFIX_PR` flag 名
+2. 保留 `RemoteTaskType` 字段不动
+3. 冲突时合并：吸收上游的 `source` 字段值变更、env var 变更，保留我们的本地 launcher 函数
+
+---
+
+## 八、测试计划
+
+### 8.1 测试文件
+
+| 文件 | 覆盖目标 | 测试用例数 |
+|---|---|---|
+| `parseArgs.test.ts` | 参数解析全分支 | ~10 |
+| `monitorState.test.ts` | 单例锁正确性 | ~6 |
+| `launchAutofixPr.test.ts` | 主流程 happy path + 失败路径 | ~12 |
+| `index.test.ts` | bridge invocation error 校验 | ~5 |
+
+### 8.2 关键断言
+
+`launchAutofixPr.test.ts`：
+
+```ts
+test('start with PR number teleports with correct args', async () => {
+  // mock teleportToRemote, registerRemoteAgentTask, detectCurrentRepositoryWithHost
+  await callAutofixPr(onDone, context, '386')
+  expect(teleportMock).toHaveBeenCalledWith(expect.objectContaining({
+    source: 'autofix_pr',
+    useDefaultEnvironment: true,
+    githubPr: { owner: 'amDosion', repo: 'claude-code-bast', number: 386 },
+    branchName: 'refs/pull/386/head',
+    reuseOutcomeBranch: 'refs/pull/386/head',
+  }))
+  expect(registerMock).toHaveBeenCalledWith(expect.objectContaining({
+    remoteTaskType: 'autofix-pr',
+  }))
+})
+
+test('cross-repo syntax owner/repo#n parses correctly', async () => {
+  await callAutofixPr(onDone, context, 'anthropics/claude-code#999')
+  expect(teleportMock).toHaveBeenCalledWith(expect.objectContaining({
+    githubPr: { owner: 'anthropics', repo: 'claude-code', number: 999 },
+  }))
+})
+
+test('singleton lock blocks second start', async () => {
+  await callAutofixPr(onDone, context, '386')
+  const result = await callAutofixPr(onDone, context, '999')
+  expect(extractError(result)).toMatch(/already monitoring.*386.*Run \/autofix-pr stop first/)
+})
+
+test('stop clears active monitor', async () => {
+  await callAutofixPr(onDone, context, '386')
+  await callAutofixPr(onDone, context, 'stop')
+  expect(getActiveMonitor()).toBeNull()
+})
+```
+
+### 8.3 Mock 策略
+
+按本仓库 `tests/mocks/` 共享 mock 习惯：
+- `tests/mocks/log.ts` 和 `tests/mocks/debug.ts` —— 必 mock
+- `bun:bundle` —— mock `feature` 返回 `true`
+- `teleportToRemote` —— 模块级 mock，断言入参
+- `registerRemoteAgentTask` —— 模块级 mock，断言入参
+- `detectCurrentRepositoryWithHost` —— mock 返回 `{ owner, name, host }`
+
+### 8.4 类型检查
+
+```bash
+bun run typecheck      # 必须零错误
+bun run test:all       # 必须全绿
+```
+
+---
+
+## 九、实施步骤（11 步清单）
+
+```
+[ ] Step 1   scripts/defines.ts + scripts/dev.ts 加 AUTOFIX_PR flag
+[ ] Step 2   src/utils/teleport.tsx 加 source?: string 字段（约 5 行）
+[ ] Step 3   删除 src/commands/autofix-pr/{index.js, index.d.ts}
+             新建 src/commands/autofix-pr/index.ts（约 50 行）
+[ ] Step 4   新建 src/commands/autofix-pr/parseArgs.ts（约 30 行）
+[ ] Step 5   新建 src/commands/autofix-pr/monitorState.ts（约 40 行）
+[ ] Step 6   新建 src/commands/autofix-pr/inProcessAgent.ts（约 60 行）
+[ ] Step 7   新建 src/commands/autofix-pr/skillDetect.ts（约 30 行）
+[ ] Step 8   新建 src/commands/autofix-pr/launchAutofixPr.ts（约 250 行）
+             照抄 reviewRemote.ts，按 §2.2 差异表改造
+[ ] Step 9   新建四份测试文件（约 150 行）
+[ ] Step 10  bun run typecheck && bun run test:all 全绿
+[ ] Step 11  dev 模式手测：
+              a. /autofix-pr 386 → 期望出现 RemoteSessionProgress 面板
+              b. /autofix-pr stop → 期望提示已停止
+              c. /autofix-pr anthropics/claude-code#999 → 期望跨仓库
+              d. 第二次 /autofix-pr 386 → 期望被单例锁拒绝
+[ ] Step 12  commit：feat: implement /autofix-pr command (replace stub)
+```
+
+预计工作量：约 600 行新增代码（含测试 150 行）。
+
+---
+
+## 十、风险与回退
+
+| 风险 | 触发场景 | 回退策略 |
+|---|---|---|
+| `source` 字段 CCR 后端不识别 | 后端只认特定枚举 | 不传该字段，看是否能跑通；如不行回头看官方 cli.js 是否传了别的字段 |
+| `subscribePR` API 在本仓库 client 不完整 | KAIROS_GITHUB_WEBHOOKS 客户端代码缺失 | 用 `.catch(() => {})` 容忍失败，订阅是 nice-to-have |
+| 用户账号无 CCR 权限 | `checkRemoteAgentEligibility` 返回 false | 命令降级到错误文案，不破坏会话 |
+| 远端能起 session 但不修代码 | env vars 命名错误 | 看 `getRemoteTaskSessionUrl` 给的会话页容器日志，调整 |
+| PR 在 fork 仓库且 CCR 没访问权 | `git_repository source error` | 命令应在前置检查中识别并提示用户先把 PR 转到主仓 |
+| 上游恢复官方实现导致冲突 | 上游 sync 时 | 项目是 fork，本地实现优先；冲突手工 merge |
+
+### 回退命令
+
+```bash
+# 完全撤回本次实现
+git checkout main
+git worktree remove E:/Source_code/Claude-code-bast-autofix-pr
+git branch -D feat/autofix-pr
+```
+
+`AUTOFIX_PR` flag 默认在 production 关闭，所以即使代码已合入 main，没显式 `FEATURE_AUTOFIX_PR=1` 时不会影响用户。
+
+---
+
+## 十一、验收清单
+
+实施完成后逐项核对：
+
+- [ ] R1：dev 模式下输入 `/au` 出现 `/autofix-pr` 补全
+- [ ] R2：`/autofix-pr anthropics/claude-code#999` 不报 repo-not-allowed
+- [ ] R3：远端 session 跑完后目标 PR 出现新 commit
+- [ ] R4：其他 stub（`share` 等）依然 hidden
+- [ ] R5：`bun run typecheck` 零错误
+- [ ] R6：通过 RC bridge 触发 `/autofix-pr 386` 能跑通
+- [ ] R7：`/autofix-pr stop` 终止当前监控
+- [ ] R8：第二次 `/autofix-pr` 不同 PR 时被锁拒绝并提示

+**日期**：2026-05-06
+**适用范围**：本 session 累积所有恢复/新建命令（PR-1 ~ PR-4 + audit-fix + H2 refactor）
+**起点 commit**：`origin/main` (4f1649e2)
+**最新 commit**：`fe99cf0e`（35+ commits ahead）
+
+---
+
+## 测试前准备
+
+```bash
+cd E:/Source_code/Claude-code-bast-autofix-pr
+
+# 1. 确保最新 dist 含全部 commits
+bun run build
+
+# 2. 验证 dist 不是 stale
+stat -c '%Y %n' dist/cli.js
+git log -1 --format=%ct\ %h
+# dist mtime 必须 ≥ HEAD commit time
+
+# 3. 完全退出当前 dev REPL（按 Ctrl+D 或 /quit）后重启
+bun run dev
+```
+
+**关键提醒**：Bun 不会动态重载 dist，任何 source 改动都必须 `bun run build` + 重启 REPL。

+
+---
+
+## D 组 — _（已删除 2026-05-06）_
+
+`/providers` 命令在 2026-05-06 移除。理由:与 fork 原生 `/login` 的 "Anthropic Compatible Setup" form 功能重叠（同样配 OpenAI-compat Base URL + API Key），保留单一入口避免双 UI 混淆。
+
+**第三方 provider 配置请用** `/login` 内的 form:选 provider 后填 Base URL + API Key + Haiku/Sonnet/Opus 类别按钮。
+
+`src/services/providerRegistry/*` utility 模块 **保留**（4 内置 cerebras/groq/qwen/deepseek 元数据 + DeepSeek 三模式 compatMatrix），可被未来 fork form 的 "Quick Select" enhancement 复用。

+**E 组失败诊断**：
+- AES 错 passphrase → 提示重新 setSecret
+- keychain 不可用 → 自动 fallback 文件（warn 一次）
+- path traversal 接受 → audit-fix-all-40 修复未生效，重新 build
+
+---
+
+## F 组 — Workspace API key（需配 `ANTHROPIC_API_KEY=sk-ant-api03-*`）
+
+**前置**：
+1. 从 https://console.anthropic.com/settings/keys 创建 API key（`sk-ant-api03-*`）
+2. Windows: `setx ANTHROPIC_API_KEY "sk-ant-api03-..."` 持久化
+3. **完全退出 dev REPL**（Ctrl+D / `/quit`） + 启动新 shell（让 setx 生效）+ `bun run dev`
+4. 验证：`/login` 应显示 `☑ Workspace API key  ANTHROPIC_API_KEY set`
+
+| # | 命令 | 输入 | 期望输出 | 通过 |

+| F13 | 不配 key 时调 `/vault list`（手动 `/help` 找不到，但直接输入命令名） | — | 501 + 文案 "ANTHROPIC_API_KEY required" | ☐ |
+
+**F 组失败诊断**：
+- 401 with workspace key → key 没生效（重启 REPL + 检查 `echo $ANTHROPIC_API_KEY`）
+- 命令仍 isHidden → dist staleness（rebuild + 重启）
+- credential value 出现在 stdout → audit fix 未生效

+## 已知限制
+
+| 命令 | 限制 |
+|---|---|
+| `/teleport` 无参 picker | 用 list-style 不是 Ink `<SelectInput>`（LocalJSXCommandCall 不能 mid-call suspend） |
+| `/autofix-pr` cross-repo | 仅元数据，git source 仍来自 cwd（`repo_mismatch` 显式拒绝跨 cwd） |
+| `/skill-store install` | 写到 `~/.claude/skills/`，fork 主流程不自动 load 该目录的 markdown skills（用户手动用） |

 When you need to delegate work that benefits from full conversation context (e.g., continuing a multi-file refactor where the child needs the same system prompt and history), use \`fork: true\`. For most tasks, prefer specialized agent types (Explore, Plan, general-purpose).

+- User says "what did I note about X?" → list_stores → list_entries → fetch
+- User says "continue from where we left off" → check stores for relevant context
+- User says "use my saved API conventions" → fetch the relevant note

+# Feature: 20260510_F001 - multi-encoding-file-tools
+
+## 需求背景
+
+当前文件读写工具（FileReadTool、FileWriteTool、FileEditTool）的编码检测非常简单——仅通过 BOM 头识别 UTF-8 和 UTF-16LE，其他所有情况默认按 UTF-8 处理。对于 GBK/GB2312 等非 BOM 编码文件，读取时会产生乱码，导致 AI 模型无法正确理解和编辑这些文件。
+
+这在中文 Windows 用户场景中尤其常见：许多旧项目、日志文件、配置文件使用 GBK 编码，当前工具链无法处理。
+
+## 目标
+
+- 文件读取时自动检测编码并正确解码，对 AI 模型完全透明（不增加 encoding 参数）
+- 文件写入时保持原文件编码，不改变用户的编码习惯
+- 覆盖 GBK 编码（最常见非 UTF-8 CJK 编码），latin1 作为最终兜底
+- 零外部依赖，仅使用 Node.js/Bun 内置的 TextDecoder/TextEncoder
+
+## 范围变更
+
+**仅保留 GBK 编码支持**。Shift_JIS、EUC-JP、EUC-KR、Big5、GB18030、ISO-8859-1 已移出范围。原因：多编码回退链存在字节序列歧义（如 GBK 和 Shift_JIS 共享大量有效字节范围），导致误检测。GBK 覆盖了最核心的中文 Windows 用户场景。
+
+## 方案设计
+
+### 架构概述
+
+新增一个独立的编码工具模块 `src/utils/encoding.ts`，提供编码检测和解码/编码函数。现有文件读写路径通过调用此模块实现对非 UTF-8 编码的支持。
+
+```
+                    ┌─────────────────────────┐
+                    │   src/utils/encoding.ts  │
+                    │  detectEncoding(buffer)  │
+                    │  decodeBuffer(buf, enc)  │
+                    │  encodeString(str, enc)  │
+                    └─────────┬───────────────┘
+                              │
+              ┌───────────────┼───────────────┐
+              ▼               ▼               ▼
+     fileRead.ts      readFileInRange.ts    file.ts
+   (readFileSync     (异步读取路径)      (writeTextContent)
+   WithMetadata)
+```
+
+### 编码检测算法（三层检测）
+
+检测基于文件头部 4KB 数据，分三层依次判断：
+
+**第一层：BOM 检测（现有逻辑保留）**
+- `FF FE` → UTF-16LE
+- `EF BB BF` → UTF-8（带 BOM）
+
+**第二层：UTF-8 验证**
+- 用 `new TextDecoder('utf-8', { fatal: true })` 对头部 4KB 做解码
+- 成功 → 文件为 UTF-8（覆盖绝大多数现代源码文件）
+- 失败（抛出 TypeError）→ 进入第三层
+
+**第三层：GBK 回退**
+- 用 `new TextDecoder('gbk', { fatal: true })` 尝试解码头部 4KB
+- 成功 → 文件为 GBK（覆盖中文 Windows 用户最常见的非 UTF-8 编码）
+- 失败 → `latin1`（单字节编码，永远成功，作为最终兜底）
+
+```typescript
+// src/utils/encoding.ts 核心逻辑
+
+export type FileEncoding = BufferEncoding | 'gbk'
+export type DetectedEncoding = string
+
+export function detectEncoding(buffer: Buffer): FileEncoding {
+  // Layer 1: BOM
+  if (buffer.length >= 2 && buffer[0] === 0xff && buffer[1] === 0xfe) {
+    return 'utf-16le'
+  }
+  if (buffer.length >= 3 && buffer[0] === 0xef && buffer[1] === 0xbb && buffer[2] === 0xbf) {
+    return 'utf-8'
+  }
+
+  // Layer 2: UTF-8 validation
+  try {
+    new TextDecoder('utf-8', { fatal: true }).decode(buffer)
+    return 'utf-8'
+  } catch {}
+
+  // Layer 3: GBK fallback
+  try {
+    new TextDecoder('gbk', { fatal: true }).decode(buffer)
+    return 'gbk'
+  } catch {}
+
+  return 'latin1'
+}
+```
+
+### 读取路径改造
+
+#### `src/utils/fileRead.ts` — `detectEncodingForResolvedPath`
+
+将现有的 BOM-only 检测替换为调用 `encoding.ts` 的 `detectEncoding` 函数。返回值从 `BufferEncoding` 改为 `FileEncoding`（`BufferEncoding | 'gbk'`）。
+
+`readFileSyncWithMetadata` 函数先读 raw Buffer，再用 `decodeBuffer` 解码，而非使用 `fs.readFileSync` 的 encoding 选项（该选项只接受 `BufferEncoding`，不支持 `gbk`）。
+
+#### `src/utils/readFileInRange.ts` — 异步读取
+
+当前两个路径（fast path 和 streaming path）都硬编码 `encoding: 'utf8'`：
+
+**Fast path 改造**：
+- `readFile` 改为读取 Buffer（去掉 encoding 参数）
+- 读取后调用 `detectEncoding(buffer)` 检测编码
+- 用 `decodeBuffer` 解码为字符串
+- 后续行处理逻辑不变
+
+**Streaming path 改造**：
+- `createReadStream` 去掉 `encoding: 'utf8'`，改为 Buffer 模式
+- 第一个 chunk 做编码检测（同时保留 BOM 剥离逻辑）
+- 后续 chunk 拼接后用 `TextDecoder` 解码
+- 注意：streaming 路径需要特殊处理——先收集足够字节做检测，再逐行扫描
+
+**Streaming 编码处理策略**：
+streaming 路径改为两阶段：
+1. **检测阶段**：前 4KB 数据到达后立即检测编码
+2. **解码阶段**：用检测到的编码创建一个 `TextDecoder`（`{ stream: true }` 模式），逐 chunk 解码
+
+### 写入路径改造
+
+#### 编码回写策略
+
+写入时需要将内部 UTF-8 字符串编码回原文件编码。由于 `TextEncoder` 只支持 UTF-8 输出，需要使用 `TextDecoder` 的反向操作。
+
+**最终决定**：对于非 UTF-8 文件的写回，尝试使用 `Buffer.from(content, encoding)` 编码，失败则自动转换为 UTF-8 并在结果消息中注明。这样既满足了零依赖约束，也避免了数据损坏。
+
+#### `src/utils/file.ts` — `writeTextContent`
+
+现有函数签名 `writeTextContent(filePath, content, encoding, lineEndings)` 已接受 encoding 参数。需要：
+- 扩展类型，接受 `FileEncoding` 而非仅 `BufferEncoding`
+- 对于 UTF-8 和 UTF-16LE，行为不变
+- 对于 GBK，使用 `encodeString` 函数尝试编码，失败则回退为 UTF-8 写入
+
+#### `FileWriteTool` 和 `FileEditTool`
+
+这两个工具的 `call` 方法中，`writeTextContent` 调用已传递 `encoding`（来自 `readFileSyncWithMetadata` 的返回值）。改动很小——只需确保类型系统接受新编码名。
+
+### 类型扩展
+
+```typescript
+// 扩展编码类型 — 仅添加 GBK
+export type FileEncoding = BufferEncoding | 'gbk'
+```
+
+在 `readFileSyncWithMetadata` 返回类型中将 `encoding` 从 `BufferEncoding` 改为 `FileEncoding`。
+
+## 实现要点
+
+### 关键技术决策
+
+1. **检测只用头部 4KB**：避免全文件扫描，性能开销极小（多几次 TextDecoder 调用，每次 ~1μs）
+2. **GBK 作为唯一回退**：中文 Windows 用户最多，且避免了多编码回退链的字节序列歧义问题
+3. **TextDecoder fatal 模式**：`{ fatal: true }` 是检测的关键——如果字节序列不符合编码规范会抛异常，借此区分不同编码
+4. **streaming 路径的两阶段设计**：先攒够检测数据再开始行扫描，避免半字符解码问题
+5. **latin1 最终兜底**：单字节编码永远成功，确保任何文件都能被读取
+
+### 难点
+
+1. **Streaming 编码解码**：`TextDecoder` 支持 `{ stream: true }` 模式处理多字节字符的 chunk 边界，但需要在检测完成前缓冲数据
+2. **编码回写的零依赖方案**：`TextEncoder` 只输出 UTF-8，非 UTF-8 编码回写需要额外处理。务实方案是 UTF-8 写入 + 消息提示
+3. **混合编码文件**：极少见，不在本次覆盖范围内
+
+### 依赖
+
+- 零外部依赖，仅使用 `TextDecoder`（Node.js 13+ / Bun 内置 full-icu）
+- Bun 运行时对 GBK 的 TextDecoder 支持已验证可用（Bun 1.3.13）
+

+### Acceptance Task: 多编码文件工具验收
+
+**前置条件:**
+- 所有 Task 0-4 已执行完毕
+- 运行环境: 当前开发环境（Bun）
+
+**范围变更:** 仅保留 GBK 编码支持，Shift_JIS/EUC-JP/EUC-KR/Big5/GB18030/ISO-8859-1 已移除。
+
+**端到端验证:**
+
+1. 运行完整测试套件确保无回归
+   - `bun run precheck`
+   - 预期: typecheck + lint fix + test 全部零错误通过
+   - 失败排查: 检查各 Task 的测试步骤，特别是 Task 1 的编码检测测试和 Task 3 的 readFileInRange 测试
+
+2. 验证 GBK 文件读取正确性
+   - 创建 GBK 编码测试文件：`bun -e "const fs = require('fs'); const b = Buffer.from([0xC4, 0xE3, 0xBA, 0xC3, 0xCA, 0xC0, 0xBD, 0xE7, 0x0A]); fs.writeFileSync('/tmp/test-gbk.txt', b)"`
+   - 读取并验证：`bun -e "import { readFileSyncWithMetadata } from './src/utils/fileRead.js'; const r = readFileSyncWithMetadata('/tmp/test-gbk.txt'); console.log('encoding:', r.encoding); console.log('content:', r.content)"`
+   - 预期: encoding 为 `gbk`，content 为 "你好世界"
+   - 失败排查: 检查 Task 1 的 detectEncoding 逻辑、Task 2 的 readFileSyncWithMetadata 集成
+
+3. 验证 UTF-8 文件读取回归
+   - `bun -e "import { readFileSyncWithMetadata } from './src/utils/fileRead.js'; const fs = require('fs'); fs.writeFileSync('/tmp/test-utf8.txt', 'Hello 世界\n'); const r = readFileSyncWithMetadata('/tmp/test-utf8.txt'); console.log('encoding:', r.encoding); console.log('content:', r.content)"`

+   - 失败排查: 检查 Task 1 的 UTF-8 fatal 验证逻辑
+
+4. 验证 UTF-16LE 文件读取回归
+   - `bun -e "const fs = require('fs'); const b = Buffer.concat([Buffer.from([0xFF, 0xFE]), Buffer.from('Hello', 'utf16le')]); fs.writeFileSync('/tmp/test-utf16le.txt', b); import { readFileSyncWithMetadata } from './src/utils/fileRead.js'; const r = readFileSyncWithMetadata('/tmp/test-utf16le.txt'); console.log('encoding:', r.encoding); console.log('content:', r.content)"`
+   - 预期: encoding 为 `utf-16le`，content 为 "Hello"
+   - 失败排查: 检查 Task 1 的 BOM 检测层、Task 2 的集成
+
+5. 验证 readFileInRange 异步路径的 GBK 支持
+   - `bun -e "import { readFileInRange } from './src/utils/readFileInRange.js'; const r = await readFileInRange('/tmp/test-gbk.txt', 0); console.log('content:', r.content); console.log('totalLines:', r.totalLines)"`
+   - 预期: content 为 "你好世界"，totalLines 为 1
+   - 失败排查: 检查 Task 3 的 fast path 改造
+
+6. 验证 GBK 文件写入（UTF-8 回退）
+   - `bun -e "import { writeTextContent } from './src/utils/file.js'; writeTextContent('/tmp/test-gbk-write.txt', '测试写入', 'gbk', 'LF'); const fs = require('fs'); const content = fs.readFileSync('/tmp/test-gbk-write.txt', 'utf8'); console.log('written:', content)"`
+   - 预期: 文件成功写入，内容为 "测试写入"（UTF-8 回退或 GBK 编码均可接受）
+   - 失败排查: 检查 Task 4 的 writeTextContent 改造和 encodeString 函数
+
+7. 验证编码检测性能
+   - `bun -e "import { detectEncoding } from './src/utils/encoding.js'; const buf = Buffer.alloc(4096, 0x41); const start = performance.now(); for (let i = 0; i < 1000; i++) detectEncoding(buf); console.log('avg:', (performance.now() - start) / 1000, 'ms')"`
+   - 预期: 平均检测耗时 < 1ms
+   - 失败排查: 检查 Task 1 的检测逻辑是否有不必要的重复操作

+### Task 1: 编码检测核心模块
+
+**背景:**
+当前 `src/utils/fileRead.ts` 的 `detectEncodingForResolvedPath` 仅通过 BOM 头识别 UTF-8 和 UTF-16LE，其他所有文件一律返回 `utf8`，导致 GBK 等非 UTF-8 编码文件读取乱码。本 Task 新建独立的编码检测工具模块 `src/utils/encoding.ts`，实现三层编码检测算法（BOM → UTF-8 fatal 验证 → GBK 回退），为后续 Task 2/3/4 的读写路径改造提供统一的编码检测和解码能力。本 Task 无前置依赖，是后续所有 Task 的基础。
+
+**涉及文件:**
+- 新建: `src/utils/encoding.ts`
+- 新建: `src/utils/__tests__/encoding.test.ts`
+
+**执行步骤:**
+
+- [x] 创建 `src/utils/encoding.ts`，定义类型
+  - 位置: 文件顶部
+  - 导出以下类型:
+    ```typescript
+    /** 扩展编码类型，覆盖最常见的非 UTF-8 CJK 编码 */
+    export type FileEncoding = BufferEncoding | 'gbk'
+
+    /** TextDecoder 接受的编码名（string），比 FileEncoding 更宽泛 */
+    export type DetectedEncoding = string
+    ```
+  - 原因: 后续 Task 2/3/4 需要这些类型来做编码标注和类型收窄
+
+- [x] 实现 `detectEncoding(buffer: Buffer): FileEncoding` 函数
+  - 位置: `src/utils/encoding.ts`，类型定义之后
+  - 三层检测逻辑:
+    ```typescript
+    export function detectEncoding(buffer: Buffer): FileEncoding {
+      // Layer 1: BOM 检测（与现有 fileRead.ts 逻辑一致）
+      if (buffer.length >= 2 && buffer[0] === 0xff && buffer[1] === 0xfe) {
+        return 'utf-16le'
+      }
+      if (
+        buffer.length >= 3 &&
+        buffer[0] === 0xef &&
+        buffer[1] === 0xbb &&
+        buffer[2] === 0xbf
+      ) {
+        return 'utf-8'
+      }
+
+      // Layer 2: UTF-8 fatal 验证
+      // fatal: true 模式下，无效 UTF-8 字节序列会抛出 TypeError
+      try {
+        new TextDecoder('utf-8', { fatal: true }).decode(buffer)
+        return 'utf-8'
+      } catch {
+        // 不是合法 UTF-8，进入 Layer 3
+      }
+
+      // Layer 3: GBK 回退
+      try {
+        new TextDecoder('gbk', { fatal: true }).decode(buffer)
+        return 'gbk'
+      } catch {
+        // 不是合法 GBK，latin1 作为最终兜底
+      }
+
+      return 'latin1'
+    }
+    ```
+  - 原因: BOM 必须优先于 fatal 验证；GBK 作为唯一回退避免了多编码链的字节歧义问题；latin1 单字节编码永远成功
+
+- [x] 实现 `decodeBuffer(buffer: Buffer, encoding: DetectedEncoding): string` 函数
+  - 位置: `src/utils/encoding.ts`，`detectEncoding` 之后
+  - 逻辑:
+    ```typescript
+    export function decodeBuffer(
+      buffer: Buffer,
+      encoding: DetectedEncoding,
+    ): string {
+      return new TextDecoder(encoding).decode(buffer)
+    }
+    ```
+  - 原因: 统一解码入口，后续 Task 2/3 的读取路径都调用此函数
+
+- [x] 实现 `encodeString(content: string, encoding: DetectedEncoding): { buffer: Buffer; converted: boolean }` 函数
+  - 位置: `src/utils/encoding.ts`，`decodeBuffer` 之后
+  - 逻辑:
+    ```typescript
+    export function encodeString(
+      content: string,
+      encoding: DetectedEncoding,
+    ): { buffer: Buffer; converted: boolean } {
+      if (encoding === 'utf-8' || encoding === 'utf8') {
+        return { buffer: Buffer.from(content, 'utf-8'), converted: false }
+      }
+      if (encoding === 'utf-16le') {
+        return { buffer: Buffer.from(content, 'utf-16le'), converted: false }
+      }
+
+      // 其他编码（如 gbk）：尝试 Buffer.from，失败则回退为 UTF-8
+      try {
+        const buf = Buffer.from(content, encoding as BufferEncoding)
+        return { buffer: buf, converted: false }
+      } catch {
+        return { buffer: Buffer.from(content, 'utf-8'), converted: true }
+      }
+    }
+    ```
+  - 原因: `Buffer.from` 在 Bun 中可能支持 GBK 编码名，但 Node.js 不支持。try-catch 策略兼容两种运行时；`converted` 标志让 Task 4 的写入路径能向用户报告编码转换
+
+- [x] 为编码检测和解码函数编写单元测试
+  - 测试文件: `src/utils/__tests__/encoding.test.ts`
+  - 测试场景:
+    - **BOM 检测 — UTF-16LE**: 输入 `Buffer.from([0xff, 0xfe, 0x48, 0x00])` → 预期返回 `'utf-16le'`
+    - **BOM 检测 — UTF-8 BOM**: 输入 `Buffer.from([0xef, 0xbb, 0xbf, 0x48, 0x65])` → 预期返回 `'utf-8'`
+    - **UTF-8 验证**: 输入 `Buffer.from('Hello, 世界', 'utf-8')` → 预期返回 `'utf-8'`
+    - **GBK 检测**: 输入 `Buffer.from([0xc4, 0xe3, 0xba, 0xc3])` → 预期返回 `'gbk'`
+    - **空 buffer**: 输入 `Buffer.alloc(0)` → 预期返回 `'utf-8'`
+    - **latin1 兜底**: 输入随机字节 `Buffer.from([0x80, 0x81, 0x82, 0x83, 0x84, 0x85])` → 预期返回 `'latin1'`
+    - **BOM 优先于内容分析**: 输入带 UTF-8 BOM 的数据 → 预期返回 `'utf-8'`
+    - **decodeBuffer — UTF-8**: 输入 UTF-8 编码的 buffer + encoding `'utf-8'` → 预期返回正确的中文字符串
+    - **decodeBuffer — GBK**: 输入 GBK 编码的 buffer + encoding `'gbk'` → 预期返回正确的中文字符串
+    - **decodeBuffer — UTF-16LE**: 输入 UTF-16LE 编码的 buffer + encoding `'utf-16le'` → 预期返回正确字符串
+    - **decodeBuffer — 空 buffer**: 输入空 buffer → 预期返回空字符串
+    - **encodeString — UTF-8**: 输入字符串 + encoding `'utf-8'` → 预期 `{ converted: false }`
+    - **encodeString — utf8 别名**: 输入字符串 + encoding `'utf8'` → 预期 `{ converted: false }`
+    - **encodeString — UTF-16LE**: 输入字符串 + encoding `'utf-16le'` → 预期 `{ converted: false }`
+    - **encodeString — GBK**: 输入字符串 + encoding `'gbk'` → 预期返回有效的 Buffer（converted 视运行时而定）
+  - 运行命令: `bun test src/utils/__tests__/encoding.test.ts`
+  - 预期: 所有测试通过
+
+**检查步骤:**
+
+- [x] 验证 `encoding.ts` 文件存在且导出正确
+  - `grep -c "export" src/utils/encoding.ts`
+  - 预期: 输出 >= 4（至少导出 FileEncoding, DetectedEncoding, detectEncoding, decodeBuffer, encodeString 共 5 个导出）
+
+- [x] 验证类型检查通过
+  - `bunx tsc --noEmit src/utils/encoding.ts 2>&1 | head -5`
+  - 预期: 无类型错误输出
+
+- [x] 运行编码检测单元测试
+  - `bun test src/utils/__tests__/encoding.test.ts`
+  - 预期: 所有测试通过，无失败用例
+
+**认知变更:**
+- [x] [CLAUDE.md] `src/utils/encoding.ts` 是文件编码检测的唯一入口，提供 `detectEncoding`（三层检测：BOM → UTF-8 fatal → GBK 回退）和 `decodeBuffer`/`encodeString` 函数。检测基于文件头部 4KB，零外部依赖，仅使用 TextDecoder API。`FileEncoding` 类型为 `BufferEncoding | 'gbk'`，覆盖最常见非 UTF-8 CJK 编码。latin1 作为最终兜底编码（单字节编码永远成功）。

+### Task 2: 同步读取路径集成
+
+**背景:**
+当前同步读取路径（`fileRead.ts` → `file.ts` → `fileReadCache.ts`）的编码检测仅通过 BOM 头识别 UTF-8 和 UTF-16LE，非 BOM 编码文件一律按 UTF-8 读取导致乱码。本 Task 将 `detectEncodingForResolvedPath` 的内部实现从 BOM-only 升级为调用 Task 1 创建的 `encoding.ts` 三层检测，并将返回类型从 `BufferEncoding` 扩展为 `FileEncoding`。同时将所有 `fs.readFileSync(path, { encoding })` 调用改为先读 Buffer 再用 `decodeBuffer` 解码，以支持 `gbk` 等非 `BufferEncoding` 编码。本 Task 依赖 Task 1（`src/utils/encoding.ts`），输出被 Task 4（写入路径适配）依赖。
+
+**涉及文件:**
+- 修改: `src/utils/fileRead.ts`
+- 修改: `src/utils/file.ts`
+- 修改: `src/utils/fileReadCache.ts`
+- 新建: `src/utils/__tests__/fileRead.test.ts`
+
+**执行步骤:**
+
+- [x] 在 `fileRead.ts` 中导入 `encoding.ts` 的类型和函数
+  - 位置: `src/utils/fileRead.ts` 文件顶部 import 区域，在 `import { getFsImplementation, safeResolvePath } from './fsOperations.js'` 之后
+  - 添加导入:
+    ```typescript
+    import { type FileEncoding, decodeBuffer, detectEncoding } from './encoding.js'
+    ```
+  - 原因: 后续步骤需要 `FileEncoding` 类型、`detectEncoding` 检测函数和 `decodeBuffer` 解码函数
+
+- [x] 改造 `detectEncodingForResolvedPath` 函数，使用 `encoding.ts` 的三层检测
+  - 位置: `src/utils/fileRead.ts` 的 `detectEncodingForResolvedPath` 函数
+  - 将函数体替换为以下逻辑:
+    ```typescript
+    export function detectEncodingForResolvedPath(
+      resolvedPath: string,
+    ): FileEncoding {
+      const { buffer, bytesRead } = getFsImplementation().readSync(resolvedPath, {
+        length: 4096,
+      })
+
+      // Empty files default to utf8 — nothing to detect
+      if (bytesRead === 0) {
+        return 'utf8'
+      }
+
+      return detectEncoding(buffer.subarray(0, bytesRead))
+    }
+    ```
+  - 关键变更:
+    - 返回类型从 `BufferEncoding` 改为 `FileEncoding`
+    - 删除内联的 BOM 检测逻辑，改为调用 `detectEncoding(buffer.subarray(0, bytesRead))`
+    - 使用 `buffer.subarray(0, bytesRead)` 截取实际读取的字节，避免尾部零字节干扰检测
+  - 原因: 将检测逻辑委托给 `encoding.ts` 的三层算法，消除代码重复
+
+- [x] 改造 `readFileSyncWithMetadata` 函数，支持非 `BufferEncoding` 解码
+  - 位置: `src/utils/fileRead.ts` 的 `readFileSyncWithMetadata` 函数
+  - 将函数签名和内部逻辑改为:
+    ```typescript
+    export function readFileSyncWithMetadata(filePath: string): {
+      content: string
+      encoding: FileEncoding
+      lineEndings: LineEndingType
+    } {
+      const fs = getFsImplementation()
+      const { resolvedPath, isSymlink } = safeResolvePath(fs, filePath)
+
+      if (isSymlink) {
+        logForDebugging(`Reading through symlink: ${filePath} -> ${resolvedPath}`)
+      }
+
+      const encoding = detectEncodingForResolvedPath(resolvedPath)
+      // Read raw Buffer first — fs.readFileSync encoding option only accepts
+      // BufferEncoding, not gbk etc.
+      const rawBuffer = fs.readFileBytesSync(resolvedPath)
+      const raw = decodeBuffer(rawBuffer, encoding)
+      const lineEndings = detectLineEndingsForString(raw.slice(0, 4096))
+      return {
+        content: raw.replaceAll('\r\n', '\n'),
+        encoding,
+        lineEndings,
+      }
+    }
+    ```
+  - 关键变更:
+    - 返回类型中 `encoding` 从 `BufferEncoding` 改为 `FileEncoding`
+    - `fs.readFileSync(resolvedPath, { encoding })` 改为 `fs.readFileBytesSync(resolvedPath)` 读取 Buffer
+    - 新增 `decodeBuffer(rawBuffer, encoding)` 解码为字符串
+  - 原因: `fs.readFileSync` 的 `encoding` 选项只接受 `BufferEncoding`（utf8/utf16le/latin1 等），传入 `'gbk'` 会在运行时报错
+
+- [x] 更新 `file.ts` 中 `detectFileEncoding` 的返回类型
+  - 位置: `src/utils/file.ts` 的 `detectFileEncoding` 函数签名
+  - 将 `): BufferEncoding {` 改为 `): FileEncoding {`
+  - 在文件顶部 import 区域添加:
+    ```typescript
+    import { type FileEncoding, decodeBuffer, encodeString } from './encoding.js'
+    ```
+  - 原因: `detectFileEncoding` 调用 `detectEncodingForResolvedPath`，返回类型已改为 `FileEncoding`
+
+- [x] 更新 `file.ts` 中 `detectLineEndings` 的 encoding 参数类型和解码逻辑
+  - 位置: `src/utils/file.ts` 的 `detectLineEndings` 函数
+  - 将函数签名改为:
+    ```typescript
+    export function detectLineEndings(
+      filePath: string,
+      encoding: FileEncoding = 'utf8',
+    ): LineEndingType {
+    ```
+  - 将内部 `buffer.toString(encoding, 0, bytesRead)` 改为:
+    ```typescript
+    const content = decodeBuffer(buffer.subarray(0, bytesRead), encoding)
+    ```
+  - 原因: `buffer.toString('gbk')` 不可靠，统一使用 `decodeBuffer` 通过 `TextDecoder` 解码
+
+- [x] 更新 `fileReadCache.ts` 的类型和解码逻辑
+  - 位置: `src/utils/fileReadCache.ts`
+  - 在文件顶部 import 区域添加:
+    ```typescript
+    import { type FileEncoding, decodeBuffer } from './encoding.js'
+    ```
+  - 将 `CachedFileData` 类型中 `encoding: BufferEncoding` 改为 `encoding: FileEncoding`
+  - 将 `readFile` 方法返回类型改为 `{ content: string; encoding: FileEncoding }`
+  - 将缓存未命中读取逻辑改为:
+    ```typescript
+    const encoding = detectFileEncoding(filePath)
+    const rawBuffer = fs.readFileBytesSync(filePath)
+    const content = decodeBuffer(rawBuffer, encoding).replaceAll('\r\n', '\n')
+    ```
+  - 原因: 与 `fileRead.ts` 相同——必须改为 Buffer 读取 + `decodeBuffer` 解码
+
+- [x] 为改造后的 `detectEncodingForResolvedPath` 和 `readFileSyncWithMetadata` 编写单元测试
+  - 测试文件: `src/utils/__tests__/fileRead.test.ts`
+  - 测试场景:
+    - **UTF-8 文件读取**: 创建临时 UTF-8 文件 → 返回 `encoding: 'utf-8'`，content 与写入内容一致
+    - **GBK 文件读取**: 创建临时 GBK 编码文件 → 返回 `encoding: 'gbk'`，content 包含正确的中文字符
+    - **空文件读取**: 创建空文件 → 返回 `encoding: 'utf8'`，content 为空字符串
+    - **UTF-16LE BOM 文件读取**: 创建带 BOM 的 UTF-16LE 文件 → 返回 `encoding: 'utf-16le'`
+    - **detectEncodingForResolvedPath 返回类型**: 验证返回值为 `FileEncoding` 类型
+  - Mock 策略: 使用 `tests/mocks/debug.ts` mock `debug.ts`，使用 `tests/mocks/log.ts` mock `log.ts`
+  - 运行命令: `bun test src/utils/__tests__/fileRead.test.ts`
+  - 预期: 所有测试通过
+
+**检查步骤:**

+当前 `src/utils/readFileInRange.ts` 是 FileReadTool 的核心异步读取函数，提供 fast path（小文件整体读入）和 streaming path（大文件逐块扫描）两条路径，两者均硬编码 `encoding: 'utf8'`，导致非 UTF-8 编码文件读取乱码。本 Task 将两条路径改造为 Buffer 读取 + 编码检测 + TextDecoder 解码模式。fast path 改造简单（整体读 Buffer 后检测解码），streaming path 需要两阶段设计（先收集前 4KB 做编码检测，再用 `TextDecoder({ stream: true })` 逐 chunk 解码）。本 Task 依赖 Task 1（`src/utils/encoding.ts` 的 `detectEncoding` 和 `decodeBuffer`），输出被 Task 4 依赖（通过 `readFileInRange` 的返回值间接影响）。
+
+**涉及文件:**
+- 修改: `src/utils/readFileInRange.ts`
+- 新建: `src/utils/__tests__/readFileInRange.test.ts`
+
+**执行步骤:**
+
+- [x] 在 `readFileInRange.ts` 中导入 `encoding.ts` 的函数
+  - 位置: `src/utils/readFileInRange.ts` 文件顶部 import 区域，在 `import { formatFileSize } from './format.js'` 之后
+  - 添加导入:
+    ```typescript
+    import { detectEncoding, decodeBuffer } from './encoding.js'
+    ```
+  - 原因: fast path 和 streaming path 都需要 `detectEncoding` 做编码检测，fast path 需要 `decodeBuffer` 做一次性解码
+
+- [x] 改造 fast path — 将 `readFile` 从 UTF-8 字符串读取改为 Buffer 读取 + 检测 + 解码
+  - 位置: `src/utils/readFileInRange.ts` 的 `readFileInRange` 函数内 fast path 分支
+  - 将以下代码:
+    ```typescript
+    const text = await readFile(filePath, { encoding: 'utf8', signal })
+    return readFileInRangeFast(text, stats.mtimeMs, offset, maxLines, ...)
+    ```
+    替换为:
+    ```typescript
+    const rawBuffer = await readFile(filePath, { signal })
+    const encoding = detectEncoding(rawBuffer)
+    const text = decodeBuffer(rawBuffer, encoding)
+    return readFileInRangeFast(text, stats.mtimeMs, offset, maxLines, ...)
+    ```
+  - 关键变更: `readFile` 去掉 `encoding: 'utf8'` 选项，返回 `Buffer`；调用 `detectEncoding(rawBuffer)` 检测编码；调用 `decodeBuffer(rawBuffer, encoding)` 解码为字符串。
+  - 原因: `readFile` 的 `encoding` 选项只支持 `BufferEncoding`，不支持 `gbk` 等 ICU 编码名
+
+- [x] 改造 streaming path — 扩展 `StreamState` 类型，增加编码检测和解码相关字段
+  - 位置: `src/utils/readFileInRange.ts` 的 `StreamState` 类型定义
+  - 在现有字段之后添加以下字段:
+    ```typescript
+    type StreamState = {
+      // ... 现有字段保持不变 ...
+      /** 编码检测状态：null 表示尚未检测，string 表示已检测完成 */
+      encoding: string | null
+      /** TextDecoder 实例：检测完成后创建，用于逐 chunk 流式解码 */
+      decoder: TextDecoder | null
+      /** 检测阶段缓冲区：收集原始字节直到满 4KB 或 stream 结束 */
+      detectionBuffer: number[]
+    }
+    ```
+  - 原因: streaming 模式下 chunk 是增量到达的，需要缓冲阶段收集足够字节来调用 `detectEncoding`
+
+- [x] 改造 `streamOnData` — 处理 Buffer chunk，实现两阶段（检测阶段 + 解码阶段）
+  - 位置: `src/utils/readFileInRange.ts` 的 `streamOnData` 函数
+  - 将函数签名从 `streamOnData(this: StreamState, chunk: string): void` 改为 `streamOnData(this: StreamState, chunk: Buffer): void`
+  - 替换函数体为两阶段逻辑:
+    ```typescript
+    function streamOnData(this: StreamState, chunk: Buffer): void {
+      this.totalBytesRead += chunk.length
+
+      // ... maxBytes 检查保持不变 ...
+
+      // Phase 1: 编码检测阶段
+      if (this.encoding === null) {
+        for (let i = 0; i < chunk.length; i++) {
+          this.detectionBuffer.push(chunk[i])
+        }
+        if (this.detectionBuffer.length >= 4096) {
+          this.encoding = detectEncoding(Buffer.from(this.detectionBuffer))
+          this.decoder = new TextDecoder(this.encoding, { stream: true })
+          const decoded = this.decoder.decode(Buffer.from(this.detectionBuffer))
+          this.detectionBuffer = []
+          processTextChunk(this, decoded)
+        }
+        return
+      }
+
+      // Phase 2: 解码阶段
+      const decoded = this.decoder!.decode(chunk, { stream: true })
+      processTextChunk(this, decoded)
+    }
+    ```
+  - 原因: 两阶段设计确保编码检测在足够数据上执行（至少 4KB），检测完成后用 `TextDecoder({ stream: true })` 逐 chunk 解码
+
+- [x] 提取行扫描逻辑为独立的 `processTextChunk` 辅助函数
+  - 位置: `src/utils/readFileInRange.ts`，在 `streamOnData` 函数定义之前
+  - 从原 `streamOnData` 提取行扫描逻辑到独立函数 `processTextChunk(state: StreamState, text: string): void`
+  - 行扫描逻辑与原实现完全一致，仅变量名从 `this.` 改为 `state.`
+  - 原因: 检测阶段和解码阶段复用同一段行扫描逻辑
+
+- [x] 改造 `streamOnEnd` — 处理检测阶段缓冲区残留和最终 fragment
+  - 位置: `src/utils/readFileInRange.ts` 的 `streamOnEnd` 函数
+  - 在函数体开头插入检测阶段完成逻辑:
+    ```typescript
+    if (this.encoding === null) {
+      this.encoding = detectEncoding(Buffer.from(this.detectionBuffer))
+      this.decoder = new TextDecoder(this.encoding, { stream: true })
+      const decoded = this.decoder.decode(Buffer.from(this.detectionBuffer))
+      this.detectionBuffer = []
+      processTextChunk(this, decoded)
+    }
+    ```
+  - 原因: 小文件可能 < 4KB，stream 在检测缓冲区未满时就结束。必须在 `streamOnEnd` 中完成检测和解码
+
+- [x] 改造 `readFileInRangeStreaming` — 创建 Buffer 模式的 stream，初始化新增字段
+  - 位置: `src/utils/readFileInRange.ts` 的 `readFileInRangeStreaming` 函数
+  - 将 `createReadStream` 调用去掉 `encoding: 'utf8'` 选项
+  - 在 `state` 对象初始化中添加新字段: `encoding: null, decoder: null, detectionBuffer: []`
+  - 原因: 去掉 `encoding: 'utf8'` 后，`data` 事件回调接收 `Buffer` 对象
+
+- [x] 更新文件顶部注释，反映编码检测能力
+  - 位置: `src/utils/readFileInRange.ts` 文件顶部注释
+  - 注释已更新为: `Both paths auto-detect encoding via encoding.ts (BOM → UTF-8 fatal → fallback chain), decode with TextDecoder, and strip BOM and \r (CRLF → LF).`
+
+- [x] 为改造后的 `readFileInRange` 编写单元测试
+  - 测试文件: `src/utils/__tests__/readFileInRange.test.ts`
+  - 测试场景:
+    - **Fast path — UTF-8 文件**: 创建临时 UTF-8 文件 → 返回正确的 `content`、`lineCount`、`totalLines`
+    - **Fast path — GBK 文件**: 创建临时 GBK 编码文件 → 返回正确的中文内容（非乱码），`totalBytes` 正确
+    - **Fast path — 带行范围读取 GBK 文件**: 创建包含多行的 GBK 文件 → 返回指定行范围，内容正确
+    - **Streaming path — 大 UTF-8 文件**: 创建超过 10MB 阈值的 UTF-8 文件 → 返回正确内容
+    - **Streaming path — 大 GBK 文件**: 创建超过 10MB 阈值的 GBK 编码文件 → 返回正确的中文内容
+    - **BOM 剥离**: 创建带 UTF-8 BOM 的文件 → `content` 不包含 BOM 字符
+    - **空文件**: 创建空文件 → `content` 为空字符串，`totalLines` 为 1，`totalBytes` 为 0
+  - 运行命令: `bun test src/utils/__tests__/readFileInRange.test.ts`
+  - 预期: 所有测试通过
+
+**检查步骤:**
+
+- [x] 验证 `readFileInRange.ts` 已导入 `encoding.ts` 的函数
+  - `grep -n "detectEncoding\|decodeBuffer" src/utils/readFileInRange.ts`
+  - 预期: import 行包含 `detectEncoding` 和 `decodeBuffer`，函数体中包含调用
+
+- [x] 验证 streaming path 不再硬编码 `encoding: 'utf8'`
+  - `grep -n "encoding: 'utf8'\|encoding: \"utf8\"" src/utils/readFileInRange.ts`
+  - 预期: 无匹配结果
+
+- [x] 验证 `createReadStream` 调用无 encoding 选项
+  - `grep -A3 "createReadStream" src/utils/readFileInRange.ts`
+  - 预期: `createReadStream` 的选项对象中不包含 `encoding` 属性
+
+- [x] 验证 `StreamState` 类型包含编码检测新字段
+  - `grep -n "encoding:\|decoder:\|detectionBuffer:" src/utils/readFileInRange.ts`
+  - 预期: `StreamState` 类型定义中包含 `encoding`、`decoder`、`detectionBuffer` 字段
+
+- [x] 验证 `processTextChunk` 函数存在
+  - `grep -n "function processTextChunk" src/utils/readFileInRange.ts`
+  - 预期: 函数定义存在
+
+- [x] 运行 readFileInRange 单元测试
+  - `bun test src/utils/__tests__/readFileInRange.test.ts`
+  - 预期: 所有测试通过
+
+- [x] 运行 precheck 确认无类型/lint/测试错误
+  - `bun run precheck`
+  - 预期: 零错误通过
+
+**认知变更:**
+- [x] [CLAUDE.md] `readFileInRange.ts` 的 streaming path 使用两阶段编码检测：先收集前 4KB 字节调用 `detectEncoding`，再用 `TextDecoder({ stream: true })` 逐 chunk 流式解码。`TextDecoder` 的 `{ stream: true }` 模式会自动处理多字节字符跨 chunk 边界问题。对于 < 4KB 的小文件，检测在 `streamOnEnd` 中完成。

+### Task 4: 写入路径和工具层适配
+
+**背景:**
+[业务语境] — 当用户通过 FileEditTool 或 FileWriteTool 编辑非 UTF-8 编码文件（如 GBK）时，写入操作需要将内部 UTF-8 字符串编码回原文件编码，否则写入的内容会乱码。当前 `writeTextContent` 只接受 `BufferEncoding` 类型，无法处理 gbk 等编码。
+[修改原因] — `writeTextContent` 的 `encoding` 参数类型为 `BufferEncoding`，`writeFileSyncAndFlush_DEPRECATED` 内部直接将 encoding 传给 `fs.writeFileSync`（只接受标准 BufferEncoding）。`FileEditTool.validateInput` 中硬编码了 BOM-only 编码检测，无法识别 GBK 文件。
+[上下游影响] — 本 Task 依赖 Task 1 创建的 `encodeString` 函数和 `FileEncoding` 类型。`FileEditTool` 和 `FileWriteTool` 通过 `writeTextContent` 间接依赖本 Task 的改造。BashTool 和 NotebookEditTool 也调用 `writeTextContent`，签名变更后它们无需额外改动（encoding 参数类型由上游传入，自动兼容）。
+
+**涉及文件:**
+- 修改: `src/utils/file.ts`
+- 修改: `packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts`
+
+**执行步骤:**
+
+- [x] 在 `src/utils/file.ts` 中合并 `encodeString` 到 Task 2 已创建的 `encoding.js` 导入
+  - 位置: 文件导入区域，Task 2 已添加的 `import { type FileEncoding, decodeBuffer } from './encoding.js'` 行
+  - 将该行改为: `import { type FileEncoding, decodeBuffer, encodeString } from './encoding.js'`
+  - 原因: 避免对同一模块创建两个 import 语句
+
+- [x] 将 `writeTextContent` 的 `encoding` 参数类型从 `BufferEncoding` 改为 `FileEncoding`
+  - 位置: `src/utils/file.ts:writeTextContent()`
+  - 修改函数签名:
+    ```typescript
+    export function writeTextContent(
+      filePath: string,
+      content: string,
+      encoding: FileEncoding,
+      endings: LineEndingType,
+    ): void
+    ```
+  - 修改函数体，在行尾处理之后、调用 `writeFileSyncAndFlush_DEPRECATED` 之前，增加编码判断逻辑:
+    ```typescript
+    const BUFFER_ENCODINGS = new Set<string>([
+      'utf8', 'utf-8', 'utf16le', 'ucs2', 'ucs-2',
+      'ascii', 'latin1', 'binary', 'base64', 'hex',
+    ])
+
+    if (BUFFER_ENCODINGS.has(encoding)) {
+      writeFileSyncAndFlush_DEPRECATED(filePath, toWrite, { encoding: encoding as BufferEncoding })
+    } else {
+      // 非 BufferEncoding（如 gbk），使用 encodeString 获取 Buffer
+      const { buffer, converted } = encodeString(toWrite, encoding)
+      writeFileSyncAndFlush_DEPRECATED(filePath, buffer, { buffer })
+      if (converted) {
+        logForDebugging(
+          `writeTextContent: encoding '${encoding}' unsupported for write, fell back to UTF-8 for ${filePath}`,
+          { level: 'warn' },
+        )
+      }
+    }
+    ```
+  - 原因: `fs.writeFileSync` 只接受标准 BufferEncoding，对于 gbk 等编码必须先转为 Buffer 再写入
+
+- [x] 扩展 `writeFileSyncAndFlush_DEPRECATED` 支持 Buffer 写入
+  - 位置: `src/utils/file.ts:writeFileSyncAndFlush_DEPRECATED()`
+  - 修改函数签名中 `content` 参数类型和 `options` 类型:
+    ```typescript
+    export function writeFileSyncAndFlush_DEPRECATED(
+      filePath: string,
+      content: string | Buffer,
+      options: { encoding?: BufferEncoding; mode?: number; buffer?: Buffer } = {},
+    ): void
+    ```
+  - 修改原子写入路径的 `writeOptions` 构建逻辑:
+    ```typescript
+    const isBufferWrite = Buffer.isBuffer(content) || options.buffer !== undefined
+    const writeData = options.buffer ?? content
+    const writeOptions: {
+      encoding?: BufferEncoding
+      flush: boolean
+      mode?: number
+    } = {
+      flush: true,
+      ...(isBufferWrite ? {} : { encoding: options.encoding ?? 'utf-8' }),
+    }
+    ```
+  - 修改非原子回退路径，使用相同的 `isBufferWrite` / `writeData` / `writeOptions` 模式
+  - 原因: `fs.writeFileSync(path, buffer)` 可以直接写入 Buffer，不需要 encoding 参数
+
+- [x] 在 `FileEditTool.ts` 中导入 `FileEncoding` 和 `detectEncoding` / `decodeBuffer`
+  - 位置: `packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts` 导入区域
+  - 添加: `import { detectEncoding, decodeBuffer, type FileEncoding } from 'src/utils/encoding.js'`
+  - 原因: `validateInput` 编码检测和 `readFileForEdit` 返回类型需要 `FileEncoding` 类型
+
+- [x] 将 `readFileForEdit` 返回类型中的 `encoding` 从 `BufferEncoding` 改为 `FileEncoding`
+  - 位置: `packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts:readFileForEdit()`
+  - 修改返回类型声明:
+    ```typescript
+    function readFileForEdit(absoluteFilePath: string): {
+      content: string
+      fileExists: boolean
+      encoding: FileEncoding
+      lineEndings: LineEndingType
+    }
+    ```
+  - 原因: `readFileSyncWithMetadata` 返回的 `encoding` 类型已由 Task 2 改为 `FileEncoding`
+
+- [x] 改造 `FileEditTool.validateInput` 中的编码检测逻辑
+  - 位置: `packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts:validateInput()`
+  - 将现有的 BOM-only 编码检测:
+    ```typescript
+    const encoding: BufferEncoding =
+      fileBuffer.length >= 2 && fileBuffer[0] === 0xff && fileBuffer[1] === 0xfe
+        ? 'utf16le'
+        : 'utf8'
+    fileContent = fileBuffer.toString(encoding).replaceAll('\r\n', '\n')
+    ```
+  - 替换为:
+    ```typescript
+    const encoding: FileEncoding = detectEncoding(fileBuffer)
+    fileContent = decodeBuffer(fileBuffer, encoding).replaceAll('\r\n', '\n')
+    ```
+  - 原因: 使 validateInput 也能正确识别 GBK 文件，避免编辑时因编码检测不一致导致 old_string 匹配失败
+
+- [x] 为 `writeTextContent` 的多编码写入能力编写单元测试
+  - 测试文件: `src/utils/__tests__/file.test.ts`
+  - 在现有测试 describe 块之后追加新的 describe('writeTextContent with multi-encoding') 块
+  - 测试场景:
+    - UTF-8 写入: 写入 UTF-8 内容 → 文件内容正确，无回退警告
+    - UTF-16LE 写入: 写入 UTF-16LE 内容（含 BOM） → 文件二进制内容与预期一致
+    - GBK 写入回退: 对 gbk 编码调用 `writeTextContent` → 文件以 UTF-8 写入（`encodeString` 回退行为），内容不损坏
+    - CRLF 行尾 + GBK: `endings: 'CRLF'` + gbk 编码 → 行尾正确转换为 `\r\n`，编码回退为 UTF-8
+  - 注意: 需要 mock `src/utils/debug.ts`（使用共享 mock `tests/mocks/debug.ts`）
+  - 运行命令: `bun test src/utils/__tests__/file.test.ts`
+  - 预期: 所有测试通过
+
+**检查步骤:**
+- [x] 验证 `writeTextContent` 签名使用 `FileEncoding` 类型
+  - `grep -n 'encoding: FileEncoding' src/utils/file.ts`
+  - 预期: 输出包含 `writeTextContent` 函数定义行
+
+- [x] 验证 `writeFileSyncAndFlush_DEPRECATED` 支持 Buffer 写入
+  - `grep -n 'content: string | Buffer' src/utils/file.ts`
+  - 预期: 输出包含 `writeFileSyncAndFlush_DEPRECATED` 函数定义行
+
+- [x] 验证 `FileEditTool.readFileForEdit` 返回类型已更新
+  - `grep -n 'encoding: FileEncoding' packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts`
+  - 预期: 输出包含 `readFileForEdit` 函数的返回类型声明
+
+- [x] 验证 `FileEditTool.validateInput` 使用 `detectEncoding`
+  - `grep -n 'detectEncoding' packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts`
+  - 预期: 输出包含 validateInput 内部的调用
+
+- [x] 运行 file.ts 单元测试
+  - `bun test src/utils/__tests__/file.test.ts`
