Compound request integration tests: stitch_responses, capture_file_id, inherit_context, CREATE+CLOSE chain

- Add FileAndBuf struct wrapping file + reusable read_buf Vec
- read(): reuse Vec capacity across calls, use unsafe set_len to skip memset
- ~15% read throughput improvement (2.6 → 3.0 GB/s on localhost smbclient)

+
+## 开发阶段
+
+### Phase 1: FSKit Module基础（已开始）✅
+- ✅ 项目结构创建
+- ✅ FSKit Module配置文件
+- ✅ 核心代码文件
+- ✅ Frame Index Table实现
+- ✅ 测试文件
+- ⏳ Xcode项目生成（下一步）
+
+### Phase 2: Frame Index Table完善（待开始）
+- ❌ 性能优化
+- ❌ Frame Interpolation APIs完善
+- ❌ 单元测试完善
+
+### Phase 3: DriverKit驱动（等待审批通过）
+- ⏳ Block Storage Device (NVMe tier)
+- ⏳ SCSI Controller (HDD tier)
+- ⏳ Networking (Object Storage tier)
+
+### Phase 4: MarkBaseFMS完整功能
+- ❌ Frame Lock mechanism完善
+- ❌ 四层统一管理界面
+- ❌ Debug Kit (IORKit)
+- ❌ 系统集成测试
+
+## 下一步操作
+
+### 1. 生成Xcode项目
+
+```bash
+cd MarkBaseFS
+xcodegen generate
+```
+
+这会根据`project.yml`生成`MarkBaseFS.xcodeproj`。
+
+### 2. 打开Xcode项目
+
+```bash
+open MarkBaseFS.xcodeproj
+```
+
+### 3. 配置签名和证书
+
+在Xcode中：
+1. 选择项目 → MarkBaseFS target
+2. Signing & Capabilities → Team: K3TDMD9Y6B
+3. Signing Certificate: Developer ID Application: Accusys,Inc (K3TDMD9Y6B)
+
+### 4. 运行测试
+
+```bash
+# 在Xcode中运行测试
+Cmd + U
+
+# 或使用命令行
+xcodebuild test -project MarkBaseFS.xcodeproj -scheme MarkBaseFS -destination 'platform=macOS'
+```
+
+### 5. 构建应用
+
+```bash
+# 在Xcode中构建
+Cmd + B
+
+# 或使用命令行
+xcodebuild build -project MarkBaseFS.xcodeproj -scheme MarkBaseFS -configuration Release
+```
+

+- **API Key Path**: ~/.appstoreconnect/AuthKey_94FCMLS254.p8
+
+### 公证流程（待实现）
+
+```bash
+# 1. 构建Release版本
+xcodebuild -project MarkBaseFS.xcodeproj -scheme MarkBaseFS -configuration Release
+
+# 2. 创建Archive
+xcodebuild archive -project MarkBaseFS.xcodeproj -scheme MarkBaseFS -archivePath build/MarkBaseFS.xcarchive
+
+# 3. 导出应用
+xcodebuild -exportArchive -archivePath build/MarkBaseFS.xcarchive -exportOptionsPlist ExportOptions.plist -exportPath build/export
+
+# 4. 签名应用
+codesign --sign "Developer ID Application: Accusys,Inc (K3TDMD9Y6B)" --deep --force --verify --verbose --options runtime build/export/MarkBaseFS.app
+
+# 5. 公证
+xcrun notarytool submit build/export/MarkBaseFS.app.zip --apple-id "your_apple_id" --password "your_password" --team-id "K3TDMD9Y6B" --wait
+
+# 6. Staple
+xcrun stapler staple build/export/MarkBaseFS.app
+```
