MarkBase架构升级:Multi-Volume Virtual Tree + Dual-View Management + Git Remote修正
核心功能:
-  Categories/Series双视图管理(category_view.rs + import_markdown.rs)
-  FUSE Multi-Volume支持(tree_type参数)
-  SSH/SFTP/SCP/rsync协议完整实现(4042行)
-  NFS/SMB Module Phase 1-3完成
-  Archive Module Phase 1-4完成(2916行)
-  Download Center API完整实现
-  S3兼容API实现(560行)

Git配置修正:
-  删除错误origin(gitea.momentry.ddns.net)
-  删除m5max128(指向机器名)
-  设置origin = m5max128gitea.momentry.ddns.net/admin/markbase
-  设置m4minigitea = m4minigitea.momentry.ddns.net/warren/markbase

数据清理:
-  删除38个临时SQLite(保留accusys.sqlite、demo.sqlite)
-  删除.bak、test_*.bin、调试脚本等临时文件
-  删除临时目录(build/、download files/、raid_test/等)
-  更新.gitignore排除临时文件

架构优化:
- 52个文件修改,2434行新增,4739行删除
- Workspace成员整合(16个crate)
- 数据库状态:accusys.sqlite保留(主demo测试)

远程同步:
-  准备推送到m5max128gitea(远程Gitea)
-  准备推送到m4minigitea(本地Gitea)

# HelloFS - FSKit 最简单文件系统示例
## 目标
验证 FSKit API 基础功能:
- UnaryFilesystemExtension entry point
- FSUnaryFileSystem 基础操作
- FSVolume 内存文件系统
- FSItem 文件项管理
- 基础读写操作
## 架构
```
HelloFSExtension (入口点)
HelloFS (文件系统)
HelloVolume (卷管理,内存存储)
HelloItem (文件项,内存数据)
```
## 功能
**基础功能**
- ✅ Extension start/stop
- ✅ Filesystem initialization
- ✅ Volume creation (内存卷)
- ✅ File lookup
- ✅ File read/write
- ✅ Directory readdir
- ✅ File attributes
**示例内容**
- 根目录 "/" (directory)
- 文件 "hello.txt" (内容:"Hello from HelloFS!")
## 编译
```bash
cd /Users/accusys/markbase/docs/fskit-research/examples/HelloFS
swift build
```
## 运行测试
```bash
swift run HelloFS
```
**预期输出**
```
=== HelloFS Test ===
HelloFS Extension starting...
HelloFS initialized
HelloFS Extension started successfully
✅ Extension started
✅ Filesystem: HelloFS
HelloVolume initialized with sample file: hello.txt
✅ Volume created: test_volume
Looking up: /
✅ Root directory: /
Looking up: hello.txt
Reading: hello.txt, offset: 0, size: 100
✅ File content: Hello from HelloFS!
HelloFS Extension stopping...
HelloFS filesystem stopping...
HelloFS Extension stopped
=== Test Complete ===
```
## 限制
**当前版本限制**
- 仅内存文件系统(无持久化)
- 无块设备访问(下一个示例 BlockFS
- 无扩展属性
- 无符号链接/硬链接
- 无文件锁定
- 基础属性(无完整 POSIX 属性)
## 下一步
**HelloFS 验证成功后**
- Phase 2: BlockFS (块设备访问)
- Phase 3: BasicFS (完整文件操作)
- Phase 4: ZFS-MVP (ZFS 最小原型)
