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）

FSKit Research Summary - macOS 27 TODO

Research Date: 2026-05-29

Status: Blocked by SIP protection, waiting for macOS 27 WWDC

✅ Completed Research

1. Rust FSKit Module (markbase-fskit)

  • Files: markbase-fskit/src/fskit/volume.rs (746 lines)
  • Operations: 18 FSKit operations implemented
  • Thread Safety: AnyThread support
  • Backend: SQLite-backed file system
  • Binary:
    • dylib: libmarkbase_fskit.dylib (34KB)
    • executable: markbase_fs (2.3MB)

2. Swift Extension Prototype

  • Bundle: ExtensionKit .appex format
  • Status: Compiled, signed, dylib embedded
  • Blocking: mount command cannot discover it

3. macOS .fs Bundle Analysis

  • Apple bundles: exfat.fs, hfs.fs analyzed
  • Format: Traditional executable tools format
  • Info.plist keys: FSMediaTypes, FSPersonalities
  • Mount helpers: mount_, .util, newfs_, fsck_

4. C POC v15 Validation

  • Performance: 649.77 MB/s verified
  • Features: Thread-safe, LRU cache, hash cache
  • Technology: FUSE-T 1.2.6
  • Status: Working, ready to use

❌ Key Blockers (macOS 26.5)

1. SIP Protection

  • /System/Library/Filesystems/ READ-ONLY (SIP protected)
  • Cannot install custom .fs bundles
  • Cannot modify Apple built-in filesystems

2. mount Discovery

  • mount -t <fsname> only searches /System/Library/Filesystems/
  • /Library/Filesystems/ NOT searched
  • No alternative discovery mechanism

3. FSKit Framework

  • /System/Library/Frameworks/FSKit.framework is header-only
  • No binary implementation
  • No ObjC class support for custom filesystems

4. Documentation

  • Apple FSKit API not publicly documented
  • Binary format requirements unknown
  • Extension discovery mechanism unknown

🎯 macOS 27 TODO (WWDC 2026)

Phase 1: WWDC Announcements Research

Step 1: Check WWDC 2026 FSKit sessions

  • Watch FSKit-related sessions
  • Check for new FSKit API documentation
  • Check for ExtensionKit FSKit support
  • Check for SIP policy changes

Step 2: Check Xcode 18 beta

  • Download Xcode 18 beta (if available)
  • Check FSKit framework binary
  • Check FSKit headers for new APIs
  • Check .fs bundle templates

Step 3: Check macOS 27 beta

  • Install macOS 27 beta
  • Test /Library/Filesystems/ discovery
  • Test SIP policy (if relaxed)
  • Test mount command behavior

Phase 2: Implementation Testing

Option A: If FSKit ObjC API released

Test Rust FSKit module:

# Check if macOS 27 recognizes .appex bundles
pluginkit -m -p com.apple.fskit

# Try mounting via FSKit
mount -t markbasefs /path/to/database /Volumes/MarkBase

Option B: If .fs bundle format supported

Test user-level installation:

# Install to /Library/Filesystems/
sudo cp -R markbasefs.fs /Library/Filesystems/

# Test mount
mount -t markbasefs /path/to/database /Volumes/MarkBase

Option C: If new FSKit Extension format

Research new format:

  • Check Apple documentation for new FSKit Extension type
  • Test new Info.plist keys
  • Test new binary format requirements

Phase 3: C POC Integration (Backup)

If FSKit still blocked:

Use C POC v15:

# Compile
gcc -Wall -O3 docs/fuse_poc/markbase_v15_balanced.c \
    -I/usr/local/include/fuse3 -L/usr/local/lib \
    -lfuse3 -lsqlite3 -lpthread \
    -Wl,-rpath,/usr/local/lib \
    -o markbase_fuse

# Run
export DYLD_LIBRARY_PATH=/usr/local/lib:$DYLD_LIBRARY_PATH
./markbase_fuse -f /tmp/mb_mount

# Performance: 649.77 MB/s (verified)
