📊 技術突破總結

1. FUSE-T Binary 發現

• ✅ 不是 /usr/local/bin/fuse-t
• ✅ 實際位置：/Library/Application Support/fuse-t/bin/go-nfsv4
• ✅ 統一 binary 支援 3種 backend

2. Backend Detection

• ✅ macOS 26.4.1 → FSKit (native, fastest)
• ✅ macOS <26 → NFSv4 (stable)
• ✅ Auto detection working
• ✅ Manual selection supported

3. SQLite-backed Operations

• ✅ getattr() - file_nodes query
• ✅ readdir() - children query
• ✅ read() - file_locations query
• ✅ Ready for real mount

4. Performance Design

• ✅ LRU cache (10,000 entries)
• ✅ Write buffer (64KB chunks)
• ✅ Target: 600MB/s write throughput

📦 立即可執行的 Phase 2 測試

Simple Mount Test

# 1. Create test source
mkdir -p /tmp/test_source
echo "Hello FUSE" > /tmp/test_source/test.txt

# 2. Mount using MarkBase CLI
cargo run -- fuse mount --user test --dir /Volumes/MarkBase_test --backend nfs

# 3. Verify mount
mount | grep MarkBase_test
ls /Volumes/MarkBase_test
cat /Volumes/MarkBase_test/test.txt

# 4. Unmount
cargo run -- fuse unmount --dir /Volumes/MarkBase_test

Warren User Mount

# 1. Mount warren user (12659 nodes)
cargo run -- fuse mount --user warren --dir /Volumes/MarkBase_warren --backend fskit

# 2. Verify file tree
ls /Volumes/MarkBase_warren | wc -l
# Expected: 12659 nodes

# 3. Test file access
find /Volumes/MarkBase_warren -name "*.jpg" | wc -l
# Expected: 2371 jpg files

# 4. Performance test (Phase 4)
# AJA System Test: 4K ProRes 4444, target 600MB/s write
