-## 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
-  pendingPermissionHandlers.delete(requestId)  // 处理后删除
-  handler(parsed)
-}
-
-// useReplBridge.tsx:712-717
-onResponse(requestId, handler) {
-  pendingPermissionHandlers.set(requestId, handler)
-  return () => {
-    pendingPermissionHandlers.delete(requestId)  // 取消时删除
-  }
-}
-```
-
-### 不确定部分
-
-hook 的 cleanup 函数（组件卸载时的 `replBridgePermissionCallbacks = undefined`）是否完整调用。
-
----
-
-## 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
-}
-```
