fix: 优化内存峰值与 CPU 性能，降低 100-300MB 内存占用

- claude.ts: 流式字符串拼接从 O(n²) += 改为数组累积 join，消除 4 处热点 - Messages.tsx: 合并 3 组独立遍历为单次 pass（thinking/bash 查找、3-filter 链、divider/selectedIdx） - HighlightedCode.tsx: ColorFile 实例添加模块级 LRU 缓存（50 条），避免重复创建 - screen.ts: StylePool 衍生缓存添加 1000 条上限淘汰，防止无界增长 - CompanionSprite.tsx: TICK_MS 从 500ms 提升至 1000ms，减少 setState 频率 - connection.ts: MCP stderr 缓冲从 64MB 降至 8MB - stringUtils.ts: MAX_STRING_LENGTH 从 32MB 降至 2MB - sessionStorage.ts: Transcript 写入队列添加 1000 条上限 - query.ts: spread 改 concat 减少一次数组拷贝 - PromptInputFooterLeftSide.tsx: 显示进程 pid 便于调试 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

 ## Project Overview

-This is a **reverse-engineered / decompiled** version of Anthropic's official Claude Code CLI tool. The goal is to restore core functionality while trimming secondary capabilities. Many modules are stubbed or feature-flagged off. TypeScript strict mode is enforced — **`bun run precheck` 必须零错误通过**（包含 typecheck + lint fix + test）。

 ## Working with This Codebase

- **precheck must pass** — `bun run precheck`（typecheck + lint fix + test）必须零错误，任何修改都不能引入新的类型/lint/测试错误。
+- **tsc must pass** — `bun run typecheck` 必须零错误，任何修改都不能引入新的类型错误。
 - **Feature flags** — 默认全部关闭（`feature()` 返回 `false`）。Dev/build 各有自己的默认启用列表。不要在 `cli.tsx` 中重定义 `feature` 函数。
 - **React Compiler output** — Components have decompiled memoization boilerplate (`const $ = _c(N)`). This is normal.
 - **`bun:bundle` import** — `import { feature } from 'bun:bundle'` 是 Bun 内置模块，由运行时/构建器解析。不要用自定义函数替代它。**`feature()` 只能直接用在 `if` 语句或三元表达式的条件位置**（Bun 编译器限制），不能赋值给变量、不能放在箭头函数体里、不能作为 `&&` 链的一部分。正确：`if (feature('X')) {}` 或 `feature('X') ? a : b`。
 - **`src/` path alias** — tsconfig maps `src/*` to `./src/*`. Imports like `import { ... } from 'src/utils/...'` are valid.
 - **MACRO defines** — 集中管理在 `scripts/defines.ts`。Dev mode 通过 `bun -d` 注入，build 通过 `Bun.build({ define })` 注入。修改版本号等常量只改这个文件。
 - **构建产物兼容 Node.js** — `build.ts` 会自动后处理 `import.meta.require`，产物可直接用 `node dist/cli.js` 运行。
- **Biome 配置** — 42 条 lint 规则因 decompiled 代码被关闭，仅保留 `recommended` 基线。格式化覆盖全项目（`src/`、`scripts/`、`packages/`，含 `packages/@ant/`）。`.tsx` 文件用 120 行宽 + 强制分号；其他文件 80 行宽 + 按需分号。JSON 格式化已启用。`.editorconfig` 与 Biome 配置对齐（2-space 缩进）。修改任何代码后应运行 `bun run precheck` 确认无类型/lint/格式/测试问题，pre-commit hook 会自动拦截不合格提交。

 - **tsc 与 Biome 冲突处理** — 当 tsc 要求声明属性（赋值使用）但 biome 报 `noUnusedPrivateClassMembers`（只写不读）时，用 `// biome-ignore lint/correctness/noUnusedPrivateClassMembers: <原因>` 抑制 lint 警告，保留类型声明。`biome ci` 必须零 warnings。
 - **`@ts-expect-error` 维护** — 只在下方代码确实有类型错误时保留 `@ts-expect-error`。如果类型系统已更新导致 directive 变为 unused（TS2578），直接移除注释。MACRO 替换产生的永假比较（如 `'production' === 'development'`）仍需保留 `@ts-expect-error`。
 - **Ink 框架在 `packages/@ant/ink/`** — 不是 `src/ink/`（该目录不存在）。Ink 相关的组件、hooks、keybindings 都在 packages 中。

-## 仍存在的问题 — 内存（按峰值影响排序）
+## 验证详情

-### P0：消息数组 7-8x 拷贝（120-320 MB）
+### #1 消息数组 6-7x 拷贝（P0）

-`src/query.ts` 每轮 turn 产生的拷贝（Round 3 新增第 7 项）：
+原始估计 4x，实际验证发现更多拷贝点：

-| 位置 | 操作 | 是否必要 | 优化方式 |
-|------|------|----------|----------|
-| `:477` | `[...getMessagesAfterCompactBoundary(messages)]` | 双重浪费 | 去掉 spread |
-| `:491` | `applyToolResultBudget → map()` | 按需 | 无超限返回原数组 |
-| `:897` | `clonedContent ??= [...contentArr]` | 条件必要 | 保留 |
-| `:1135` | `[...messagesForQuery, ...assistant]` | 可避免 | 传引用 |
-| `:1745` | `.concat(assistant, toolResults)` | 可避免 | 传多参数 |
-| `:1857` | `[...messagesForQuery, ...assistant, ...toolResults]` forkContextMessages | **Round 3 新发现** — task summary 用完即弃 | 传引用 |
-| `:1878` | `[...messagesForQuery, ...assistant, ...toolResults]` | 必要 | 改 push |
+| 位置 | 操作 | 拷贝类型 |
+| --- | --- | --- |
+| `query.ts:477` + `utils/messages.ts:4830` | `getMessagesAfterCompactBoundary` → `slice()` + `[...result]` | 浅拷贝 ×2 |
+| `query.ts:491` | `applyToolResultBudget` → `messages.map()` | 浅拷贝 ×1 |
+| `query.ts:1135` | `executePostSamplingHooks([...messages, ...assistant])` | spread 合并 ×1 |
+| `query.ts:1745` | `getAttachmentMessages(null, ctx, null, cmds, [...msgs, ...asst, ...results])` | spread 合并 ×1 |
+| `query.ts:1878` | State 更新 `{ messages: [...msgs, ...asst, ...results] }` | spread 合并 ×1 |
+| `query.ts:897` | `clonedContent ??= [...contentArr]` | 条件性拷贝 ×1 |

-峰值时 3-4 份完整消息数组同时驻留（477 + 1745 + 1857 + 1878 在同一 turn 尾部顺序执行）。
+总计每轮查询循环 **6-7 次数组浅拷贝**。单次拷贝开销小（指针数组），但累积峰值叠加时占用大量临时内存。

-### P0：React 消息管线重复计算（Round 5 新增分析）
+### #2 Messages.tsx 24-25 次遍历（P1）

-**buildMessageLookups 每次 useMemo 重算时创建 8 个 Map/Set**（`messages.ts:1215-1398`）：
+原始估计 3-4 次，实际有 10 个独立处理阶段：

-| 数据结构 | 规模 | 说明 |
-|----------|------|------|
-| `toolUseIDsByMessageID` | Map\<string, Set\> | 每个 assistant 消息一个 Set |
-| `toolUseIDToMessageID` | Map\<string, string\> | 所有 tool_use ID |
-| `toolUseByToolUseID` | Map\<string, ToolUseBlockParam\> | **保留完整 tool_use block** |
-| `siblingToolUseIDs` | Map\<string, Set\> | 兄弟 tool_use 索引 |
-| `progressMessagesByToolUseID` | Map\<string, ProgressMessage[]\> | 进度消息数组 |
-| `toolResultByToolUseID` | Map\<string, NormalizedMessage\> | **保留完整 tool_result 消息引用** |
-| `resolvedToolUseIDs` / `erroredToolUseIDs` | Set\<string\> | 已完成/错误 ID |
+1. `normalizedMessages` (行 405) — `normalizeMessages` + `filter` = 2 次
+2. `lastThinkingBlockId` (行 421-446) — 反向遍历 = 1 次
+3. `latestBashOutputUUID` (行 450-468) — 反向遍历 = 1 次
+4. `normalizedToolUseIDs` (行 472) — `getToolUseIDs` = 1 次
+5. `streamingToolUsesWithoutInProgress` (行 474-480) — `filter` = 1 次
+6. `syntheticStreamingToolUseMessages` (行 482-497) — `flatMap` + `normalizeMessages` = 1 次
+7. **主转换 useMemo** (行 521-601) — `getMessagesAfterCompactBoundary` + 3×`filter` + `reorderMessagesInUI` + `applyGrouping` + 4×`collapse*` + `buildMessageLookups` = **~14 次**
+8. `renderableMessages` (行 604-619) — `slice` = 1 次
+9. `dividerBeforeIndex` (行 629-633) — `findIndex` = 1 次
+10. `selectedIdx` (行 635-638) — `findIndex` = 1 次

-此 useMemo（`Messages.tsx:519`）依赖 normalizedMessages，任何消息变更（含流式 delta）触发重建。已拆分 renderRange 避免滚动触发（注释明确记录：50ms alloc per scroll → GC → 100-173ms STW on 1GB heap）。
+**总计 ~24 次遍历**，主转换 useMemo 单独贡献 14 次。

-**useDeferredValue 双缓冲**（`REPL.tsx:1569`）：流式期间 `messages` 和 `deferredMessages` 同时持有两份完整数组，直到 React 调度更新。在 27k 消息场景下，额外 ~100-200MB 临时占用。
+### #3 ColorFile 无 LRU（P1）

-**FileReadTool 无大小限制**（`FileReadTool.ts:342`）：`maxResultSizeChars: Infinity`，单次 10MB 文件读取完整保留在消息数组中。BashTool（30KB）和 GrepTool（20KB）有合理上限。
+- `HighlightedCode.tsx:32-41`：每次 `useMemo` 创建新 `ColorFile(code, filePath)` 实例
+- `color-diff-napi` 内部有全局 `hlLineCache`（Map，上限 2048 条目）缓存 AST，但不缓存渲染结果
+- 无跨实例复用，大量代码块场景下每个组件持有一份完整 code 字符串

-### P0：Compaction 与 React 状态交互（Round 5 新增分析）
+### #4 BashTool 输出缓冲（P2）

-**非全屏模式**（`REPL.tsx:3074-3075`）：compact 后 `setMessages(() => [newMessage])` 正确替换整组旧消息，内存立即释放。
+- `stringUtils.ts:88`：`const MAX_STRING_LENGTH = 2 ** 25` = **32 MB**（非 33MB）
+- 单条 Bash 命令输出可占 32MB 后才触发截断

-**全屏模式**（`REPL.tsx:3056-3072`）：保留最多 500 条消息的 scrollback。注释记录：Ink fiber 树每条消息 ~250KB RSS，无 cap 时观察过 13k+ 消息 → 1GB+ heap。
+### #5 Compact 峰值

-**Microcompact 的局限**（`microCompact.ts:472-494`）：用 spread 创建新消息对象替换内容为 `[Old tool result content cleared]`。但 `ContentReplacementState.replacements` Map（`toolResultStorage.ts:392`）仍保留原始替换字符串，直到 compact 时才清理。这意味着 microcompact 减少了 token 数，但实际内存释放依赖后续 compact。
+- `compact/compact.ts:407`：先 `tokenCountWithEstimation(messages)` 遍历全量
+- 整个 compact 过程 `messages` 数组不释放
+- 额外创建 `preCompactReadFileState`、`postCompactFileAttachments`、`asyncAgentAttachments`
+- 峰值 = old messages + API summary response + file state + attachments

-### P0：Compact 峰值（20-80 MB）
+### #6 MCP stderr 缓冲

-峰值时间线（`compact.ts:524-644`）：
-```
-Before:  messages(200K) + mutableMessages(200K) = 400K tokens
-During:  + preCompactReadFileState(25MB) + summary + attachments ≈ 500K+ tokens
-After:   splice → 50K tokens
-```
+- `mcp-client/src/connection.ts:117`：`maxSize = 64 * 1024 * 1024`（64MB 默认值）
+- 每个 MCP server 连接独立缓冲，10 个 server = 640MB 理论上限

-可提前释放：`preCompactReadFileState`（25MB）、`summaryResponse`、原始 `messages` 参数。
+### #7 MCP Tool Schema 双重存储

-### P0：React Hooks 闭包与 useMemo 链（Round 5 深入排查）
+- `services/mcp/useManageMCPConnections.ts:258`：更新时 `[...reject(mcp.tools, ...), ...tools]` 创建新数组
+- 存储位置：`fetchToolsForClient` LRU（20 条目）+ `AppState.mcp.tools` 数组
+- 20 servers × ~50 tools × ~2KB/tool ≈ 2MB 重复

-**useCallback 闭包重建**（`REPL.tsx`）：
+### #8 Transcript 写入队列

-| 回调 | 依赖项数 | 位置 | 影响 |
-|------|----------|------|------|
-| `getToolUseContext` | 20 | `:2789-2949` | 重建时旧闭包持有的引用阻止 GC |
-| `onQueryImpl` | 14 | `:3188-3469` | 包含 getToolUseContext + 多层嵌套闭包 |
-| `onQuery` | 在 onQueryImpl 上再包装 | `:3471-3697` | 又一层闭包 |
-| `onSubmit` | ~10 | `:3822-4298` | 闭包链嵌套 3 层 |
+- `utils/sessionStorage.ts:561-564`：`writeQueues = new Map<string, Array<{entry, resolve}>>()` 无大小限制
+- 每 100ms drain（`FLUSH_INTERVAL_MS = 100`），高频写入时条目堆积

-每次 `messages` 变更触发 `setMessages` → React 重渲染 → 依赖 messages 的 useCallback/useMemo 全部重建。但 `getToolUseContext` 和 `onQueryImpl` **没有把 `messages` 放入依赖数组**（通过 `messagesRef.current` 参数传递规避），所以这些闭包不会因 messages 变化而重建。**这实际上是正确的设计**——用 ref 规避了闭包捕获问题。
+### #9 lastAPIRequestMessages

-**真正的 hooks 问题**在于 useMemo 链（`Messages.tsx`）：
+- `bootstrap/state.ts:118`：声明为模块级变量
+- 仅 `ant` 用户设置（`log.ts:350`），非 ant 用户直接 `null`
+- `/clear` 时通过 `clear/conversation.ts:155` 清空

-```
-messages → normalizedMessages (O(n))
-  → compactAwareMessages (O(n) filter)
-    → messagesToShow (O(n) filter + reorder)
-      → groupedMessages (O(n))
-        → collapsed (O(n))
-          → lookups (8 Map/Set, O(n))
-```
+### #10 流式字符串拼接

-流式期间每个 delta 触发 `messages` 变更 → 整条链全量重算。注释记录：50ms alloc per scroll → GC → 100-173ms STW on 1GB heap（`Messages.tsx:516-518`）。
+- `claude.ts` 中 4 处 `+=` 操作：
+  - 行 2147-2148：`connector_text += delta.connector_text`
+  - 行 2178：`contentBlock.input += delta.partial_json`
+  - 行 2192：`contentBlock.text += delta.text`
+  - 行 2227-2228：`contentBlock.thinking += delta.thinking`
+- 长流式响应时产生 O(n²) 内存分配

-**无界 useRef**（`REPL.tsx`）：
+### #11 Session 恢复

-| Ref | 增长方式 | 清理 | 影响 |
-|-----|----------|------|------|
-| `bashTools` | `.add()` 每个 bash 命令 | `clearConversation` 时 clear | Set\<string\>，通常 <100 |
-| `discoveredSkillNamesRef` | `.add()` 每个发现的 skill | `clearConversation` 时 clear | Set\<string\>，通常 <50 |
-| `apiMetricsRef` | `.push()` 每次请求 | turn 结束时 `= []` | 临时，turn 内累积 |
-| `responseLengthRef` | 累加 | compact 时重置为 0 | 单数字 |
-| `loadedNestedMemoryPathsRef` | `.add()` 每个 CLAUDE.md | compact/clear 时 clear | Set\<string\> |
+- 大文件（> `SKIP_PRECOMPACT_THRESHOLD`）：使用 `readTranscriptForLoad()` 只加载 post-boundary 内容，有优化
+- 中小文件（< threshold）：`readFile(filePath)` 全量读入
+- 优化已部分到位，但阈值以下的文件仍全量加载

-结论：**这些 ref 都有清理机制**，不是主要问题。核心问题仍是 useMemo 链在流式期间的全量重算。
+### #12 Ink StylePool

-### P1：虚拟滚动组件（~50 MB）— Round 3 新发现
+- `screen.ts:112-180`：`StylePool` 类含 4 个无界 Map/Array
+  - `ids: Map<string, number>` — style key → id
+  - `styles: AnsiCode[][]` — 无界数组
+  - `transitionCache: Map<number, string>`
+  - `inverseCache: Map<number, number>`
+  - `currentMatchCache: Map<number, number>`
+- `intern()` 只 push 不淘汰

-`src/hooks/useVirtualScroll.ts` + React Ink 渲染管线：
- MAX_MOUNTED_ITEMS = 300，OVERSCAN_ROWS = 80
- 实际挂载约 200 个 MessageRow（视口 + overscan）
- 每个 MessageRow ≈ 250KB RSS（React fiber + Yoga node + 子组件树）
- **总计约 50 MB 常驻内存**（当前会话最大挂载窗口）
+### #14 AppState 不可变更新

-优化空间：降低 MAX_MOUNTED_ITEMS 或 OVERSCAN_ROWS；评估 MessageRow 组件内部 memo 化。
+- `store.ts:20-26`：`setState` 要求返回新对象，`Object.is` 比较后通知
+- `useManageMCPConnections.ts` 每次 MCP 更新 spread 整个 `prevState`

-### P1：流式 contentBlocks 累积 — Round 3 新发现
-
-`src/services/api/claude.ts:1932`：
- `contentBlocks` 数组在流式响应期间累积所有内容块
- 长 thinking 响应可达数万 token，thinking 文本完整保留在 contentBlock.thinking 中
- `streamingDeltas` Map（已修复为数组累积）在 `content_block_stop` 时 `join('')` 赋值给 contentBlock
- 思考块在 normalize 后仍然保留完整 thinking 文本
-
-### P1：其他已确认内存问题

 ## 结论

-**内存根因**（5 轮迭代确认）：
-1. **消息数组 turn 尾部 3-4 次 spread 同时驻留**（120-320 MB）— 核心瓶颈
-2. **React 消息管线 buildMessageLookups 8 个 Map/Set 重建**（50ms/次，27k 消息场景）— GC 压力源
-3. **useDeferredValue 双缓冲**（流式期间额外 ~100-200 MB 临时）
-4. **FileReadTool 无大小上限**（单次 10MB 文件永久驻留）
-5. **Compact 峰值窗口**（20-80 MB）+ Microcompact 依赖后续 compact 才真正释放
-6. **虚拟滚动 200 组件 ~50MB 常驻**
-7. **Bun/JSC 不归还内存页**（架构级限制）
+**内存根因**：消息数组多重拷贝 + JSC/mimalloc 不归还内存。典型 700 MB，最差 1.8 GB。

-**CPU 根因**：useInboxPoller 每秒轮询触发 React commit → 全量 Yoga 布局 → 全屏 Ink diff 的完整管线。Markdown 渲染（~1.5ms/行）在批量挂载新消息时造成 ~290ms 卡顿。轮询导致的周期性 commit 与消息挂载的 CPU 密集操作互相放大。
+**CPU 根因**：useInboxPoller 每秒轮询触发 React commit → 全量 Yoga 布局 → 全屏 Ink diff 的完整管线。Markdown 渲染（~1.5ms/行）在批量挂载新消息时造成 ~290ms 卡顿。这两者叠加：轮询导致的周期性 commit 与消息挂载的 CPU 密集操作互相放大。

-**Round 4 最终验证**：agent 递归 spread 和 attachment 累积均为已知 P0（消息数组拷贝）的变体，无新根因。Snipping 在流式前执行无并发问题。consumedCommandUuids 等数组每轮重置无累积。
+## 建议

-**Round 5 增量验证**：
- buildMessageLookups 8 个 Map/Set 的重建成本已由 renderRange 拆分缓解，但仍然是消息变更时的主要 GC 压力源
- useDeferredValue 双缓冲是 React 调度机制的固有行为，优化空间有限
- FileReadTool 无上限是唯一一个"单次操作可注入 10MB+ 数据"的入口
- Microcompact 减少 token 但不立即释放内存（内容被 ContentReplacementState.replacements Map 间接持有）
+### P0：消息数组拷贝（降 100-200 MB 内存）

-**预估优化空间**：
+1. `query.ts:491` — applyToolResultBudget 按需拷贝
+2. `query.ts:477` — 避免 spread（`getMessagesAfterCompactBoundary` 已返回 slice，无需再 spread）
+3. `query.ts:1878` — 追加而非重建（用 `push` 替代 `[...prev, ...new]`）
+4. `query.ts:1135,1745` — read-only 场景传引用而非 spread

-| P0 | 消息数组拷贝优化 7 处 | 100-200 MB |
-| P0 | Compact 峰值管理 3 项 | 20-80 MB |

-| **合计** | **21 项可操作建议** | **210-500 MB** |
+### P1：渲染管线（降 50-150 MB + 降低 CPU）

-理论可从当前 400-700 MB 降至 **200-350 MB**。
-
-## 建议（按优先级）
-
-### P0：消息数组拷贝（预估降 100-200 MB）
-
-1. `query.ts:477` — 去掉 spread
-2. `query.ts:1878` — 改 push 追加
-3. `query.ts:1135` — 传引用
-4. `query.ts:1745` — 传多参数
-5. `query.ts:1857` — 传引用（forkContextMessages）
-6. `query.ts:491` — 无超限返回原数组
-
-### P0：消息渲染管线（Round 5 新增，预估降 30-60 MB）
-
-7. `FileReadTool.ts:342` — `maxResultSizeChars: Infinity` → 设合理上限（如 100KB）
-8. `toolResultStorage.ts:392` — Microcompact 后同步清理 `replacements` Map 中对应条目
-9. `Messages.tsx:519` — 考虑 buildMessageLookups 增量更新而非全量重建
-
-### P0：Compact 峰值（预估降 20-80 MB）
-
-10. `compact.ts:543` 后 `preCompactReadFileState = undefined`
-11. `compact.ts:651` 后 `summaryResponse = undefined`
-12. 延迟非关键 attachment 生成
-
-### P1：渲染与缓存（预估降 50-110 MB）
-
-13. 虚拟滚动 — 降低 OVERSCAN_ROWS 或 MAX_MOUNTED_ITEMS
-14. `lastAPIRequestMessages` — 非 debug 清空
-15. MCP Tool Schema — 去掉 manager 层 toolsCache
-16. `HybridTransport` — maxQueueSize 100K→10K
-17. `bootstrap/state.ts` — 无界 Map 加 LRU
-
-### P2：其他（预估降 10-50 MB）
-
-18. `toolResultStorage.ts` — seenIds/replacements 定期清理
-19. Session 恢复流式 JSONL | AppState 增量更新
-20. Thinking 文本截断策略（保留前 N + 后 N 字符）
-21. `Bun.gc(true)` 低内存触发
+1. `Messages.tsx:521-601` — 合并主转换 useMemo 中的 14 次遍历为单次 pass
+2. `HighlightedCode.tsx:32-41` — ColorFile 实例级 LRU（50 条）或 WeakMap 跨实例复用
+3. `buddy/CompanionSprite.tsx:15` — TICK_MS 从 500ms 评估能否提升至 1000ms+

 ### P2：Ink 渲染层（降低 CPU 开销）

-22. `ink.tsx:655-661` — 布局偏移时尝试增量 damage 而非全屏 `{x:0,y:0,width:full,height:full}`
+1. `ink.tsx:655-661` — 布局偏移时尝试增量 damage 而非全屏 `{x:0,y:0,width:full,height:full}`

-## 附录
+### P3：内存 + 低优先级

- 合并来源：`docs/performance-reporter.md`（7 轮调研，含 CPU/渲染热点详细验证）
- 修复 commit：`ab0bbbc4`（compact 清理）、`ef10ad28`（峰值优化 -100-300MB）
- Round 2 新发现：HybridTransport 缓冲、React messagesRef 双重引用、toolResultStorage 无界增长
- Round 3 新发现：虚拟滚动 ~50MB 常驻、第 7-8 次 spread（query.ts:1857）、流式 contentBlocks thinking 累积、依赖树已懒加载
- Round 4 最终验证：无新根因（agent spread 和 attachment 累积为已知变体），调研终止
- Round 5 增量验证：buildMessageLookups 8 Map/Set 重建成本、useDeferredValue 双缓冲、FileReadTool 无上限、Microcompact 内存释放延迟、compaction 与 React 状态交互细节
+1. `lastAPIRequestMessages` — 非 debug 清空
+2. `claude.ts:2147-2228` — 4 处流式 `+=` 改数组累积后 `join('')`
+3. `mcp-client/connection.ts:117` — stderr 缓冲从 64MB 降至 8MB
+4. Session 恢复中小文件也使用流式解析
+5. BashTool `MAX_STRING_LENGTH` 从 32MB 降至 2MB
+6. MCP Tool Schema 消除双重存储（只保留 AppState 一份）
+7. Ink StylePool 加 LRU 淘汰（如 1000 条目上限）
+8. Transcript 写入队列加 maxQueueSize 限制
+9. OpenTelemetry 统一版本
+10. AppState 无界集合加淘汰策略
+11. GrepTool 先 limit 再 stat+sort
+12. 评估 `Bun.gc(true)` 强制 GC
