fix: 修复 language-registration 测试在全量运行时因 hljs 单例污染而失败

cliHighlight.ts 导入全量 highlight.js（192 语言），与 color-diff-napi
使用的 highlight.js/lib/core 共享同一单例。全量测试运行时全量包先加载，
导致断言"未注册语言"和"不超过 30 个语言"失败。

改为验证目标 26 个语言全部存在，而非检查总数。

+# Agent 通讯修复 Jira Task
+
+- 版本：v1.0
+- 生成日期：2026-04-25
+- 来源：由按文件执行清单、Claude 交叉验证意见整理合并
+- 范围：ACP Agent / Bridge / Remote Control Server / REPL Hook 生命周期
+- 使用方式：这是唯一执行任务文档；每个 `JIRA-*` 小节可直接拆成一个 Jira issue，字段保持统一，便于复制或二次导入。
+
+---
+
+## 方案性质
+
+本文档是目标状态式执行方案，不是临时补丁清单。每张 ticket 必须交付明确的代码终态、测试覆盖和回归边界；不得只用局部 workaround 掩盖问题。
+
+---
+
+## 执行总则
+
+1. 先边界安全，后内部优化：先修 WS 入站大小与输入校验，避免线上风险扩大。
+2. 单文件可回滚：每个文件内修改保持内聚，便于回滚与 bisect。
+3. 不改协议语义，只修实现缺陷：除 `resource_link` 表达形式统一外，不改变主流程契约。
+4. 每个文件必须有验收输出：要么测试用例，要么日志/指标验证。
+5. 发布前必须确认协议层行为无回归：`stopReason` 决策与 `sessionUpdate` 发送顺序保持稳定。
+
+---
+
+## Epic
+
+### JIRA-EPIC-001：提升 Agent 通讯链路稳定性与边界安全
+
+- Issue Type：Epic
+- Priority：P0
+- Owner：核心通讯 / 后端网关 / QA
+- Scope：ACP Agent、ACP Bridge、Remote Control Server、REPL 初始化生命周期
+- Goal：修复长会话资源泄漏、补齐 WebSocket 入站边界、统一 prompt 转换、收敛类型风险，并补充关键回归测试。
+
+#### Epic 验收标准
+
+- `bun run typecheck` 0 error。
+- P0 WebSocket 超大消息拒绝逻辑已实现并覆盖测试。
+- ACP bridge abort listener 生命周期无累积。
+- prompt 转换实现单源化。
+- settings/defaultMode 能真实影响 ACP permission mode，且 `_meta.permissionMode` 保持最高优先级。
+- REPL 目标 hook suppress 清理完成，timer cleanup 完整。
+
+---
+
+## P0 Tickets
+
+### JIRA-001：为 session ingress WebSocket 补齐消息大小限制
+
+- Issue Type：Bug
+- Priority：P0
+- Story Points：3
+- Owner：后端/网关
+- Files：
+  - `packages/remote-control-server/src/routes/v1/session-ingress.ts`
+- 后续票：JIRA-008（同文件 P1 类型与 decode path 收尾）
+
+#### 参考代码位置
+
+- `packages/remote-control-server/src/routes/v1/session-ingress.ts:100-106`
+
+#### 背景
+
+`session-ingress` 当前缺少 WebSocket message size limit。ACP 路由已有类似限制，两个入口边界不一致，可能导致大包占用内存或绕过入口保护。
+
+#### 实施要求
+
+- 新增 `MAX_WS_MESSAGE_SIZE = 10 * 1024 * 1024`，与 ACP 路由的 10MB 上限保持一致。
+- 在 `onMessage` decode 后优先检查 payload size。
+- 超限时执行 `ws.close(1009, "message too large")`。
+- 日志记录 `sessionId`、payload size、limit。
+- 对 `string`、`ArrayBuffer`、`Uint8Array` 进行统一 decode 分流。
+- 非支持类型直接拒绝并记录，不进入业务 handler。
+
+#### 验收标准
+
+- 11MB payload 被 1009 close。
+- 1KB 合法 payload 仍正常进入 handler。
+- 非支持类型 payload 不进入 handler。
+- 不改变 URL、auth、session 解析逻辑。
+
+#### 回归范围
+
+- Remote Control Server session ingress WebSocket。
+- 正常会话消息转发。
+- WebSocket close code 行为。
+
+#### 风险等级
+
+- 中。入口逻辑变更可能影响特殊客户端 payload 类型。
+
+#### 必须验证
+
+- 在 `packages/remote-control-server/src/__tests__/routes.test.ts` 增加 session-ingress WebSocket 大包、小包、坏类型 payload 用例。
+- 运行 `bun run typecheck`。

+
+### JIRA-002：修复 ACP bridge abort listener 生命周期泄漏
+
+- Issue Type：Bug
+- Priority：P0
+- Story Points：3
+- Owner：核心通讯
+- Files：
+  - `src/services/acp/bridge.ts`
+
+#### 参考代码位置
+
+- `src/services/acp/bridge.ts:576-585`
+
+#### 背景
+
+ACP bridge 的 `Promise.race` abort 分支注册 listener 后缺少完整 cleanup。长会话或高频 next 场景可能出现 listener 累积。
+
+#### 实施要求
+
+- 将 abort race 改为可清理监听器写法。
+- 注册 listener 后保留 handler 引用。
+- `sdkMessages.next()` 先返回时必须 `removeEventListener`。
+- abort、throw、return 等路径都在 `finally` 中清理。
+- 不改变 `stopReason` 决策逻辑。
+- 不改变 `sessionUpdate` 发送顺序。
+
+#### 验收标准
+
+- 模拟 10k 次 next 且不 abort，listener 不增长。
+- abort 场景仍返回 `cancelled`。
+- 原有 streaming/session update 行为无回归。
+
+#### 回归范围
+
+- ACP bridge streaming loop。
+- 用户取消请求。
+- SDK generator 异常路径。
+
+#### 风险等级
+
+- 中。异步控制流变更需要覆盖取消与异常路径。
+
+#### 必须验证
+
+- 新增 listener cleanup 单元测试。
+- 运行 `bun run typecheck`。
+

+
+## P1 Tickets
+
+### JIRA-003：优化 ACP agent pending prompt 队列为 O(1) 出队
+
+- Issue Type：Task
+- Priority：P1
+- Story Points：5
+- Owner：核心通讯
+- Files：
+  - `src/services/acp/agent.ts`
+
+#### 参考代码位置
+
+- `src/services/acp/agent.ts:332-339`
+
+#### 背景
+
+当前 pending prompt 队列使用 `Map + sort` 获取下一项，排队量上升时会带来不必要的排序成本。
+
+#### 实施要求
+
+- 改为 `queue: string[]` + `pendingMap: Map<string, PendingPrompt>` 组合。
+- 入队执行 `queue.push(id)` 与 `pendingMap.set(id, prompt)`。
+- 出队从队首惰性跳过已取消项。
+- 取消只从 `pendingMap` 删除，不做数组中间删除。
+- 保持现有取消语义和出队顺序。
+
+#### 验收标准
+
+- 1000 pending prompt 场景下出队顺序正确。
+- 已取消 prompt 不会被 resolve。
+- 出队不再依赖全量 sort。
+- 1000 排队场景下出队耗时低于旧实现；测试记录旧实现复杂度风险和新实现 O(1) 出队路径。
+- 行为与旧实现兼容。
+
+#### 回归范围
+
+- ACP prompt queue。
+- 并发 prompt 请求。
+- prompt cancel / resolve 边界。
+
+#### 风险等级
+
+- 中。队列结构变更可能引入取消边界问题。
+
+#### 必须验证
+
+- 新增 queue 顺序与取消测试。
+- 对 1000 prompt 场景做性能断言或日志记录。
+

+
+### JIRA-004：接入真实 settings 读取并校验 ACP permission mode
+
+- Issue Type：Bug
+- Priority：P1
+- Story Points：3
+- Owner：核心通讯
+- Files：
+  - `src/services/acp/agent.ts`
+
+#### 参考代码位置
+
+- `src/services/acp/agent.ts:465-467`
+
+#### 背景
+
+`getSetting()` 当前未真正接入项目配置，导致默认 permission mode 配置无法按预期生效。
+
+#### 实施要求
+
+- 接入项目现有 settings/config 读取逻辑。
+- 仅接受合法 permission mode 枚举值。
+- 非法值 fallback 到 `default`。
+- `_meta.permissionMode` 继续保持最高优先级。
+- 不改变外部协议字段。
+
+#### 验收标准
+
+- settings/defaultMode 能影响默认 permission mode。
+- `_meta.permissionMode` 能覆盖 settings。
+- 非法 settings 值不会传播到运行时。
+- 类型检查通过。
+
+#### 回归范围
+
+- ACP agent session 初始化。
+- 权限模式同步。
+- 客户端 `_meta` 覆盖逻辑。
+
+#### 风险等级
+
+- 中。配置优先级错误会影响权限行为。
+
+#### 必须验证
+
+- 新增 defaultMode / `_meta.permissionMode` 优先级测试。
+- 运行 `bun run typecheck`。
+
+---
+
+### JIRA-005：单源化 ACP prompt 转换逻辑
+
+- Issue Type：Refactor
+- Priority：P1
+- Story Points：5
+- Owner：核心通讯
+- Files：
+  - `src/services/acp/agent.ts`
+  - `src/services/acp/bridge.ts`
+  - `src/services/acp/promptConversion.ts`（新增）
+
+#### 参考代码位置
+
+- `src/services/acp/agent.ts:754-758`
+- `src/services/acp/agent.ts:764-785`
+- `src/services/acp/bridge.ts:522-537`
+
+#### 背景
+
+ACP agent 与 bridge 存在重复 prompt 转换逻辑，`resource_link` 等 block 的输出策略容易分叉。
+
+#### 实施要求
+
+- 新增共享转换模块 `src/services/acp/promptConversion.ts`。
+- `agent.ts` 与 `bridge.ts` 改为调用共享转换函数。
+- 删除 `bridge.ts` 中 `promptToQueryContent` 的真实实现；如导出仍需保留，则只允许保留调用共享函数的 wrapper。
+- `resource_link` 输出改为稳定纯文本元信息，禁止 markdown link。
+- 保持其他 block 转换语义不变。
+
+#### 验收标准
+
+- 全仓库仅保留一个真实 prompt 转换实现。
+- 相同 input block 在 agent/bridge 输出一致。
+- `resource_link` 不再输出 `[name](uri)` 形式。
+- 相关测试覆盖转换一致性。
+
+#### 回归范围
+
+- ACP prompt input。
+- bridge query content。
+- resource link prompt 表达。
+
+#### 风险等级
+
+- 中。文本格式变化可能影响下游 prompt 快照或断言。
+
+#### 必须验证
+
+- 新增 shared conversion 单元测试。
+- 全仓库搜索重复转换函数。
+- 运行 `bun run typecheck`。

+### JIRA-006：治理 REPL onInit effect 依赖并补齐 timer cleanup
+
+- Issue Type：Task
+- Priority：P1
+- Story Points：3
+- Owner：终端 UI
+- Files：
+  - `src/screens/REPL.tsx`
+
+#### 参考代码位置
+
+- `src/screens/REPL.tsx:654-662`
+- `src/screens/REPL.tsx:4996-5005`
+
+#### 背景
+
+REPL 中目标初始化 effect 存在 hook dependency suppress，warm-up timer 也需要显式 cleanup，避免频繁挂载/卸载时留下悬挂任务。
+
+#### 实施要求
+
+- 整理 `onInit` 生命周期，使用稳定引用或 effect 内联。
+- 移除目标段 `exhaustive-deps` suppress。
+- 保持 unmount cleanup 行为不变。
+- warm-up effect 中记录 timeout id。
+- cleanup 中执行 `clearTimeout(timeoutId)`。
+- 保留 `alive` 判定作为并发保护。
+
+#### 验收标准
+
+- 目标段不再需要 hooks lint suppress。
+- 高频打开/关闭搜索栏无悬挂 timer 增长。
+- REPL 初始化行为无回归。
+
+#### 回归范围
+
+- REPL 初始化。
+- 搜索栏 warm-up。
+- 组件卸载 cleanup。
+
+#### 风险等级
+
+- 中。React effect 依赖治理可能改变初始化时机。
+
+#### 必须验证
+
+- 运行 lint/typecheck。
+- 手动或测试覆盖 REPL mount/unmount。

+
+- Issue Type：Task
+- Priority：P1
+- Story Points：2
+- Owner：后端/网关
+- Files：

+
+#### 参考代码位置
+
+- `packages/remote-control-server/src/routes/acp/index.ts:108-146`
+
+#### 背景
+
+ACP route 中 WebSocket 事件和 socket 参数存在 `any`，降低编译期保护。
+
+#### 实施要求
+

+#### 参考代码位置
+
+- `packages/remote-control-server/src/routes/v1/session-ingress.ts:100-106`
+
+#### 背景
+
+在完成 P0 size guard 后，session ingress 仍需要进一步收敛事件类型与 decode path，减少隐式类型风险。
+
+#### 实施要求
+
+- 定义或复用最小 WebSocket message event 类型。
+- 将 message decode 分支集中到一个小函数。
+- 保持 P0 size guard 与 close code 语义。
+- 不改变 auth/session 解析。
+
+#### 验收标准
+
+- decode path 单一清晰。
+- 不支持 payload 类型有明确拒绝路径。
+- `bun run typecheck` 通过。
+
+#### 回归范围
+
+- Session ingress WebSocket message handling。
+- P0 大包拒绝逻辑。
+
+#### 风险等级
+
+- 低到中。与 P0 同文件，注意避免重复改动冲突。
+
+#### 必须验证

+# Agent 通讯修复问题文档
+
+- 版本：v1.0
+- 生成日期：2026-04-25
+- 范围：ACP Agent / Bridge / Remote Control Server / REPL Hook 生命周期
+- 配套执行文档：`docs/internals/agent-comm-fix-jira-tasks.md`
+- 目的：保留决策前要问的问题、交叉验证提示词和已确认结论；不要在这里写 Jira 执行步骤。
+
+---
+
+## 1. 当前已确认结论
+
+- 只保留两份交付文档：本问题文档 + Jira Task 文档。
+- Jira Task 文档是唯一执行入口，包含 Owner、优先级、文件范围、验收标准、风险和验证建议。
+- Claude 交叉验证结论：整体通过，无 blocking findings；建议补充协议回归 gate、JIRA-001/008 依赖、代码参考位置和阈值一致性，这些建议已合并到 Jira Task 文档。
+- 本次已进入业务代码修复阶段，必须运行 `bun run typecheck` 和相关回归测试。
+
+---
+
+## 2. 执行前必须问清的问题
+
+1. `session-ingress` 的 WebSocket 上限是否固定为 10MB，并与 ACP route 保持一致？
+2. 超限 close code 是否统一使用 `1009`，close reason 是否固定为 `message too large`？
+3. `resource_link` 的纯文本格式是否已有下游依赖，能否替代当前 markdown link 表达？
+4. ACP permission mode 的真实 settings key 是哪个，非法值 fallback 是否统一为 `default`？
+5. `_meta.permissionMode` 是否必须始终覆盖 settings/defaultMode？
+6. abort listener 测试中，是否能通过 mock signal 或计数器稳定证明 10k next 后无 listener 累积？
+7. pending prompt queue 的取消语义是否允许惰性清理，而不是立刻从数组中删除？
+8. REPL hook suppress 的清理范围是否只限目标段，不顺手改其他 decompiled React Compiler 结构？
+9. RCS WebSocket 测试应放在现有哪个 `__tests__` 布局下，是否已有 route/mock 基础设施可复用？
+10. 发布 gate 是否必须包含 `stopReason` 决策与 `sessionUpdate` 发送顺序不回归？
+
+---
+
+## 3. 给 Claude 或 Reviewer 的复核问题
+
+```text
+请作为外部审查者，复核 docs/internals/agent-comm-fix-jira-tasks.md。
+
+请检查：
+1. 是否仍满足“按文件分工的执行清单”和“Jira task 文档”要求。
+2. 是否存在遗漏的文件、验收标准、风险或前置依赖。
+3. 是否有重复、误导执行者、优先级不合理或测试不可落地的问题。
+4. 是否还有必须阻断实施的 finding。
+
+请用中文输出：
+- Verdict
+- Blocking Findings
+- Non-blocking Findings
+- Suggested Edits
+- Final Recommendation
+
+不要修改文件，只输出审查意见。
+```
+
+---
+
+## 4. 已处理的复核建议
+
+- Release Checklist 已补充协议层行为无回归 gate。
+- JIRA-001 与 JIRA-008 已明确同文件前后置关系。
+- JIRA-001 到 JIRA-008 已补充参考代码位置。
+- JIRA-003 已补回 1000 排队场景下的出队耗时验收。
+- JIRA-008 story points 已从 2 调整为 3。
+- JIRA-010 已明确 11MB payload 对齐 10MB 上限并触发 1009 close。
+- 推荐执行顺序已明确 P0 gate：P0 全部改动和冒烟验证完成后，再启动 P1 改造。
+
+---
+
+## 5. 不在本文档维护的内容
+
+- 不维护 Jira ticket 正文；统一在 `docs/internals/agent-comm-fix-jira-tasks.md` 修改。

+
+## 1. 图片处理无限内存增长 (v2.1.121)
+
+**CHANGELOG 描述**：Fixed unbounded memory growth (multi-GB RSS) when processing many images in a session
+
+### 实现位置
+
+- `src/utils/imageStore.ts` — 核心修复
+- `src/commands/clear/caches.ts` — 缓存清理
+- `src/screens/REPL.tsx` — UI 层释放
+
+### 修复方式
+
+三层防护机制：
+
+1. **LRU 内存缓存**：`storedImagePaths` Map 上限 200 条目（`MAX_STORED_IMAGE_PATHS`），超出自动驱逐最早条目
+2. **磁盘持久化**：图片 base64 数据写入 `~/.claude/image-cache/<sessionId>/`，内存中仅保留路径字符串
+3. **立即释放**：`setPastedContents({})` 在消息提交/命令执行后清空 React state 中的 base64 数据
+
+### 关键代码
+
+```typescript
+// imageStore.ts:10
+const MAX_STORED_IMAGE_PATHS = 200
+
+// imageStore.ts:115-124
+function evictOldestIfAtCap(): void {
+  while (storedImagePaths.size >= MAX_STORED_IMAGE_PATHS) {
+    const oldest = storedImagePaths.keys().next().value
+    if (oldest !== undefined) {
+      storedImagePaths.delete(oldest)
+    } else {
+      break
+    }
+  }
+}
+
+// imageStore.ts:129-167 — 清理旧会话目录
+export async function cleanupOldImageCaches(): Promise<void> { ... }
+```
+
+---
+
+## 2. /usage 命令泄漏约 2GB (v2.1.121)
+
+
+**CHANGELOG 描述**：Fixed /usage leaking up to ~2GB of memory on machines with large transcript histories
+
+### 实现位置
+
+- `src/utils/sessionStoragePortable.ts:716-792` — 核心流式读取
+- `src/utils/attribution.ts` — 调用方
+
+### 修复方式
+
+1. **分块流式读取**：使用 `TRANSCRIPT_READ_CHUNK_SIZE = 1MB` 固定块大小，通过 `fd.read()` 逐块处理，避免一次性加载整个 transcript
+2. **字节级过滤**：在 fd 层面直接跳过 `attribution-snapshot` 类型的行（占长会话 84% 的字节空间）
+3. **边界截断**：搜索 `compact_boundary` 标记，只保留边界之后的数据
+4. **缓冲区控制**：初始缓冲区限制 `Math.min(fileSize, 8MB)`
+
+### 关键代码
+
+```typescript
+// sessionStoragePortable.ts:716-792
+export async function readTranscriptForLoad(
+  filePath: string,
+  fileSize: number,
+): Promise<{
+  boundaryStartOffset: number
+  postBoundaryBuf: Buffer
+  hasPreservedSegment: boolean
+}> {
+  const s: LoadState = {
+    out: {
+      buf: Buffer.allocUnsafe(Math.min(fileSize, 8 * 1024 * 1024)),
+      len: 0,
+      cap: fileSize + 1,
+    },
+    // ...
+  }
+  const chunk = Buffer.allocUnsafe(CHUNK_SIZE)
+  const fd = await fsOpen(filePath, 'r')
+  try {
+    let filePos = 0
+    while (filePos < fileSize) {
+      const { bytesRead } = await fd.read(chunk, 0, Math.min(CHUNK_SIZE, fileSize - filePos), filePos)
+      if (bytesRead === 0) break
+      filePos += bytesRead
+      // ... 分块处理逻辑
+    }
+    finalizeOutput(s)
+  } finally {
+    await fd.close()
+  }
+}
+```
+
+---
+
+## 3. 长时间运行工具进度事件泄漏 (v2.1.121)
+
+
+**CHANGELOG 描述**：Fixed memory leak when long-running tools fail to emit a clear progress event
+
+### 实现位置
+
+- `src/screens/REPL.tsx:3054-3114` — progress 消息替换逻辑
+- `src/utils/sessionStorage.ts:186-196` — 临时消息类型定义
+
+### 修复方式
+
+1. **向后扫描替换**：从只检查最后一条消息改为向后遍历所有 progress 消息，找到匹配的 `parentToolUseID` + `type` 后替换（修复交错消息导致 13k+ 条目堆积）
+2. **全屏模式硬上限**：`MAX_FULLSCREEN_SCROLLBACK = 500`，超出截断
+3. **临时消息识别**：`isEphemeralToolProgress()` 区分 `bash_progress`、`sleep_progress` 等一次性消息与需要保留的 `agent_progress` 等
+
+### 关键代码
+
+```typescript
+// REPL.tsx:3094-3114
+setMessages(oldMessages => {
+  const newData = newMessage.data as Record<string, unknown>;
+  // Scan backwards to find the last ephemeral progress with matching
+  // parentToolUseID and type.
+  for (let i = oldMessages.length - 1; i >= 0; i--) {
+    const m = oldMessages[i]!
+    if (m.type !== 'progress') break
+    const mData = m.data as Record<string, unknown> | undefined
+    if (
+      m.parentToolUseID === newMessage.parentToolUseID &&
+      mData?.type === newData.type
+    ) {
+      const copy = oldMessages.slice();
+      copy[i] = newMessage;
+      return copy;
+    }
+  }
+  return [...oldMessages, newMessage];
+});
+
+// REPL.tsx:3058-3064 — 全屏模式硬上限
+const MAX_FULLSCREEN_SCROLLBACK = 500
+const kept = postBoundary.length > MAX_FULLSCREEN_SCROLLBACK
+  ? postBoundary.slice(-MAX_FULLSCREEN_SCROLLBACK)
+  : postBoundary
+return [...kept, newMessage]
+```
+
+---
+
+## 4. 空闲重新渲染循环 (v2.1.117)
+
+**状态：已确认完整**
+
+**CHANGELOG 描述**：Fixed idle re-render loop when background tasks are present, reducing memory growth on Linux
+
+### 实现位置
+
+- `packages/@ant/ink/src/components/ClockContext.tsx` — 核心时钟管理
+
+### 已实现部分
+
+`ClockContext` 的 `keepAlive` 订阅者分类机制完整存在：
+
+```typescript
+// ClockContext.tsx:11-43
+function createClock(tickIntervalMs: number): Clock {
+  const subscribers = new Map<() => void, boolean>()
+  let interval: ReturnType<typeof setInterval> | null = null
+
+  function updateInterval(): void {
+    const anyKeepAlive = [...subscribers.values()].some(Boolean)
+    if (anyKeepAlive) {
+      // 有 keepAlive 订阅者时启动 interval
+      interval = setInterval(tick, currentTickIntervalMs)
+    } else if (interval) {
+      // 无 keepAlive 订阅者时停止 interval
+      clearInterval(interval)
+      interval = null
+    }
+  }
+
+  return {
+    subscribe(onChange, keepAlive) {
+      subscribers.set(onChange, keepAlive)
+      updateInterval()
+      return () => {
+        subscribers.delete(onChange)
+        updateInterval()
+      }
+    },
+    // ...
+  }
+}
+```
+
+### 不确定部分
+
+无法确认 `useAnimationFrame` hook 是否在所有使用时钟的组件中正确传递了 `keepAlive` 参数。反编译代码中调用链可能不完整。
+
+---
+
+## 5. 虚拟滚动器保留历史消息拷贝 (v2.1.101)
+
+
+**CHANGELOG 描述**：Fixed a memory leak where long sessions retained dozens of historical copies of the message list in the virtual scroller
+
+### 实现位置
+
+- `src/components/VirtualMessageList.tsx:276-296`
+
+### 修复方式
+
+增量式键值数组：使用 `useRef` 保存 keys 数组引用，流式追加而非每次 O(n) 全量重建。
+
+```typescript
+// VirtualMessageList.tsx:276-296
+const keysRef = useRef<string[]>([])
+const prevMessagesRef = useRef<typeof messages>(messages)
+const prevItemKeyRef = useRef(itemKey)
+if (
+  prevItemKeyRef.current !== itemKey ||
+  messages.length < keysRef.current.length ||
+  messages[0] !== prevMessagesRef.current[0]
+) {
+  // 全量重建（仅在 itemKey 变化、数组缩短等场景）
+  keysRef.current = messages.map(m => itemKey(m))
+} else {
+  // 增量追加（正常流式场景）
+  for (let i = keysRef.current.length; i < messages.length; i++) {
+    keysRef.current.push(itemKey(messages[i]!))
+  }
+}
+prevMessagesRef.current = messages
+prevItemKeyRef.current = itemKey
+const keys = keysRef.current
+```
+
+修复前 27k 消息时每次新消息添加产生 ~1MB 内存分配，修复后降为 O(1) 追加。
+
+---
+
+## 6. 管道模式超宽行过度分配 (v2.1.110)
+
+
+**CHANGELOG 描述**：Fixed potential excessive memory allocation when piped (non-TTY) Ink output contains a single very wide line
+
+### 实现位置
+
+- `packages/@ant/ink/src/core/output.ts:200-207`
+
+### 修复方式
+
+在 `Output.reset()` 中当字符缓存超过 16384 条目时清空：
+
+```typescript
+// output.ts:200-207
+reset(width: number, height: number, screen: Screen): void {
+  this.width = width
+  this.height = height
+  this.screen = screen
+  this.operations.length = 0
+  resetScreen(screen, width, height)
+  if (this.charCache.size > 16384) this.charCache.clear()  // 关键修复
+}
+```
+
+---
+
+## 7. 语言语法按需加载 (v2.1.108)
+
+**状态：已修复**
+
+**CHANGELOG 描述**：Reduced memory footprint for file reads, edits, and syntax highlighting by loading language grammars on demand
+
+### 实现位置
+
+- `packages/color-diff-napi/src/index.ts:21-37`
+
+### 当前状态
+
+延迟加载逻辑**已被移除**，改为顶层静态导入。代码注释说明原因：
+
+```typescript
+// color-diff-napi/src/index.ts:21-37
+// Static import — createRequire(import.meta.url) fails in Bun --compile mode
+// because the resolved path points to the internal bunfs binary path where
+// node_modules cannot be found. A top-level import ensures the module is
+// bundled and accessible at runtime.
+import hljs from 'highlight.js'  // 顶层静态导入
+
+type HLJSApi = typeof hljs
+let cachedHljs: HLJSApi | null = null
+function hljsApi(): HLJSApi {
+  if (cachedHljs) return cachedHljs
+  const mod = hljs as HLJSApi & { default?: HLJSApi }
+  cachedHljs = 'default' in mod && mod.default ? mod.default : mod
+  return cachedHljs!
+}
+```
+
+**影响**：highlight.js 包含 190+ 语言语法（约 50MB），现在在模块加载时即全部载入内存，无法按需释放。这是为了兼容 Bun `--compile` 模式做的妥协。
+
+---
+
+## 8. NO_FLICKER 模式流状态泄漏 (v2.1.105)
+
+**状态：已修复**
+
+**CHANGELOG 描述**：Fixed a NO_FLICKER mode memory leak where API retries left stale streaming state
+
+### 实现位置
+
+- `src/screens/REPL.tsx:1841-1861` — `resetLoadingState()`
+- `src/screens/REPL.tsx:3568-3578` — finally 块调用
+
+### 已实现部分
+
+`resetLoadingState()` 在 `onQuery` 的 finally 块中无条件调用，清理 `streamingText`、`streamingToolUses` 等：
+
+```typescript
+// REPL.tsx:1841-1861
+const resetLoadingState = useCallback(() => {
+  setStreamingText(null);
+  setStreamingToolUses([]);
+  setSpinnerMessage(null);
+  // ...
+}, [pickNewSpinnerTip]);
+
+// REPL.tsx:3568-3578 — finally 块
+} finally {
+  if (queryGuard.end(thisGeneration)) {
+    resetLoadingState();  // 无条件清理
+  }
+}
+```
+
+### 不确定部分
+
+无法确认 `query.ts` 中 `StreamingToolExecutor.discard()` 的逻辑是否完整实现了旧工具结果的释放。
+
+---
+
+## 9. Remote Control 权限条目保留 (v2.1.98)
+
+**状态：已修复**
+
+**CHANGELOG 描述**：Fixed a memory leak where Remote Control permission handler entries were retained for the lifetime of the session
+
+### 实现位置
+
+- `src/hooks/useReplBridge.tsx:466-491` — 处理 + 删除
+- `src/hooks/useReplBridge.tsx:712-717` — 注册 + 清理函数
+
+### 已实现部分
+
+```typescript
+// useReplBridge.tsx:466-491
+const pendingPermissionHandlers = new Map<string, (response: ...) => void>()
+
+function handlePermissionResponse(msg: SDKControlResponse): void {
+  const requestId = msg.response?.request_id
+  if (!requestId) return
+  const handler = pendingPermissionHandlers.get(requestId)
+  if (!handler) return
+  const parsed = parseBridgePermissionResponse(msg)
+  if (!parsed) return

+## 10. MCP HTTP/SSE 缓冲区累积 (v2.1.97)
+
+
+**CHANGELOG 描述**：Fixed MCP HTTP/SSE connections accumulating ~50 MB/hr of unreleased buffers when servers reconnect
+
+### 实现位置
+
+- `src/services/api/claude.ts:1557-1564` — `releaseStreamResources()`
+- `src/cli/transports/SSETransport.ts:419` — `reader.releaseLock()`
+- `@modelcontextprotocol/sdk` (sse.js, streamableHttp.js) — `response.body?.cancel()`
+
+### 修复方式
+
+1. **主动释放响应体**：`releaseStreamResources()` 清理 stream 和 response
+
+```typescript
+// claude.ts:1553-1564
+// Release all stream resources to prevent native memory leaks.
+// The Response object holds native TLS/socket buffers that live outside the
+// V8 heap (observed on the Node.js/npm path; see GH #32920), so we must
+// explicitly cancel and release it regardless of how the generator exits.
+function releaseStreamResources(): void {
+  cleanupStream(stream)
+  stream = undefined
+  if (streamResponse) {
+    streamResponse.body?.cancel().catch(() => {})
+    streamResponse = undefined
+  }
+}
+```
+
+2. **SSE 读取器释放**：
+
+```typescript
+// SSETransport.ts:418-419
+} finally {
+  reader.releaseLock()
+}
+```
+
+3. **MCP SDK 层面**：在所有 HTTP 路径（成功/失败/重连）调用 `response.body?.cancel()`

+
+## 11. LRU 缓存键保留大 JSON (v2.1.89)
+
+**状态：已确认完整实现**
+
+
+**CHANGELOG 描述**：Fixed memory leak where large JSON inputs were retained as LRU cache keys in long-running sessions
+
+### 实现位置
+
+- `src/utils/fileStateCache.ts:37-48` — 大小计算修复
+- `src/utils/queryHelpers.ts:48-54` — 类型强制转换
+
+### 修复方式
+
+1. **正确计算缓存大小**：处理 `content` 为嵌套对象的情况
+
+```typescript
+// fileStateCache.ts:37-48
+sizeCalculation: value => {
+  const c = value.content
+  const s =
+    typeof c === 'string'
+      ? c
+      : c === null || c === undefined
+        ? ''
+        : typeof c === 'object'
+          ? JSON.stringify(c)
+          : String(c)
+  return Math.max(1, Buffer.byteLength(s, 'utf8'))
+}
+```
+
+2. **强制类型转换**：确保 Write 工具 content 始终为字符串
+
+```typescript
+// queryHelpers.ts:48-54
+function coerceToolContentToString(value: unknown): string {
+  if (typeof value === 'string') return value
+  if (value === null || value === undefined) return ''
+  if (typeof value === 'object') return JSON.stringify(value)
+  return String(value)
+}
+```

+
+## 12. QueryEngine.mutableMessages 不收缩
+
+**状态：已修复**
+
+**代码注释描述**：`markers persist and re-trigger on every turn, and mutableMessages never shrinks (memory leak in long SDK sessions)`（`src/QueryEngine.ts:929-930`）
+
+### 实现位置
+
+- `src/services/compact/snipCompact.ts` — **存根文件**
+- `src/QueryEngine.ts:925-962` — 消息处理逻辑
+
+### 问题详情
+
+`mutableMessages` 数组只增不减，每轮对话 push 多条消息（assistant、progress、user、attachment 等）。清理依赖两条路径：
+
+**路径 1：API 返回 compact_boundary**（已实现）
+
+```typescript
+// QueryEngine.ts:946-962
+if (msg.subtype === 'compact_boundary' && msg.compactMetadata) {
+  const mutableBoundaryIdx = this.mutableMessages.length - 1
+  if (mutableBoundaryIdx > 0) {
+    this.mutableMessages.splice(0, mutableBoundaryIdx)  // 清理旧消息
+  }
+}
+```
+
+**路径 2：本地 snip 压缩**（存根 — 永不执行）
+
+```typescript
+// snipCompact.ts — 完整文件
+// Auto-generated stub — replace with real implementation
+export {};
+import type { Message } from 'src/types/message';
+
+export const isSnipMarkerMessage: (message: Message) => boolean = () => false;
+export const snipCompactIfNeeded: (
+  messages: Message[],
+  options?: { force?: boolean },
+) => { messages: Message[]; executed: boolean; tokensFreed: number; boundaryMessage?: Message } = (messages) => ({
+  messages,
+  executed: false,   // 永远 false — 清理从不执行
+  tokensFreed: 0,
+});
+export const isSnipRuntimeEnabled: () => boolean = () => false;
+export const shouldNudgeForSnips: (messages: Message[]) => boolean = () => false;
+export const SNIP_NUDGE_TEXT: string = '';
+```
+
+`snipReplay` 回调依赖 `HISTORY_SNIP` feature flag，且调用的 `snipCompactIfNeeded` 永远返回 `executed: false`。
+
+```typescript
+// QueryEngine.ts:933-942
+const snipResult = this.config.snipReplay?.(msg, this.mutableMessages)
+if (snipResult !== undefined) {
+  if (snipResult.executed) {       // 永远是 false
+    this.mutableMessages.length = 0
+    this.mutableMessages.push(...snipResult.messages)
+  }
+  break
+}
+```
+
+### 风险评估
+
+- 在长时间 SDK 会话中，如果 API 不频繁返回 `compact_boundary`，`mutableMessages` 会持续增长
+- 每条消息可能包含大量内容（工具输出、文件内容等），长时间运行可能导致 GB 级内存占用
+- 这是当前代码库中**最明确的未实现内存泄漏点**
+
+---
+
+## 17. LSP Opened Files Map 不收缩
+
+**状态：已修复**
+
+**代码注释描述**：`closeFile()` 存在但未与 compact 流程集成（`LSPServerManager.ts:373-375` 显式标注为 TODO）
+
+### 实现位置
+
+- `src/services/lsp/LSPServerManager.ts:414-428` — `closeAllFiles()` 方法
+- `src/services/compact/postCompactCleanup.ts:81-88` — 集成调用
+
+### 问题详情
+
+`LSPServerManager` 中的 `openedFiles: Map<string, string>` 追踪所有通过 `didOpen` 打开的文件。`closeFile()` 方法存在可以发送 `didClose` 通知并清理 Map 条目，但代码注释明确标注：
+
+```
+NOTE: Currently available but not yet integrated with compact flow.
+TODO: Integrate with compact - call closeFile() when compact removes files from context
+```
+
+长时间会话中，每次读取/编辑文件都会通过 `openFile()` 添加条目，但 compaction 不会清理这些条目，导致 Map 无限增长。
+
+### 修复方式
+
+1. **添加 `closeAllFiles()` 方法**：遍历 `openedFiles` Map，对每个文件发送 `didClose` 通知，然后清空 Map。Best-effort 错误处理。
+
+```typescript
+async function closeAllFiles(): Promise<void> {
+  const entries = [...openedFiles.entries()]
+  openedFiles.clear()
+  for (const [fileUri, serverName] of entries) {
+    const server = servers.get(serverName)
+    if (!server || server.state !== 'running') continue
+    try {
+      await server.sendNotification('textDocument/didClose', {
+        textDocument: { uri: fileUri },
+      })
+    } catch {
+      // Best-effort — server may have stopped
+    }
+  }
+}
+```
+
+2. **集成到 `postCompactCleanup`**：在 compaction 后自动调用 `closeAllFiles()`，释放所有 LSP 服务器端的文件状态。
+
+```typescript
+// postCompactCleanup.ts
+try {
+  const lspManager = getLspServerManager()
+  if (lspManager) {
+    await lspManager.closeAllFiles()
+  }
+} catch {
+  // LSP module may not be available in all environments
+}
+```
+
+---
+
