Warren ffc3f03744 Implement block-level checksum: Phase 1-4 complete
Phase 1: VfsBlockChecksum struct + JSON storage (~240 lines)
- VfsBlockChecksum: offset + SHA-256 hash
- VfsChecksumFile: block_size + algorithm + blocks + file_size
- compute_block_hash() + verify_block_hash()
- ChecksumMode: Lazy (default) + OnRead
- ScrubResult: total/verified/corrupted/repaired blocks metrics

Phase 2: ChecksumFile wrapper (~180 lines)
- VfsFile wrapper with transparent checksum
- Lazy verification (only on scrub)
- Cache of verified blocks
- Update checksum on flush()
- read_at/write_at support

Phase 3: Scrub API (~150 lines)
- scrub_file(): verify single file integrity
- scrub_all(): recursive directory scrub
- create_checksums_for_file(): generate checksums
- repair_block(): placeholder for RAID/Dedup

Phase 4: RAID repair integration (~160 lines)
- repair_block_from_parity(): reconstruct from RAID parity
- reconstruct_from_p(): XOR reconstruction for RaidZ1
- reconstruct_from_pq/pqr(): placeholder for RaidZ2/3

Tests: 15 checksum tests pass (465 total)

Momentry Display Engine - Markdown渲染與檔案樹管理系統

功能特色

  • Markdown渲染支援表格、footnote、tasklist -檔案樹管理SQLite持久化
  • REST API18+路由)
  • macOS音訊控制音訊裝置切換、音量控制 -多種顯示模式tree, list, grid_sm, grid_lg

##安裝

###必要條件

  • Rust 1.92+
  • macOS音訊功能需 macOS
  • SwitchAudioSource音訊裝置切換
#安裝 Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

#安裝 SwitchAudioSourcemacOS
brew install switchaudio-source

###建構

cargo build

##使用

###啟動伺服器

cargo run -- display                #預設 port 11438
cargo run -- display -p8080         #自訂 port
cargo run -- display README.md      #顯示指定檔案

###渲染 Markdown

cargo run -- render README.md       #輸出到 stdout
cargo run -- render README.md -o output.html

##測試

cargo test                          #執行所有測試
cargo test test_insert              #執行特定測試

File Tree功能

REST API

路由 方法 功能
/api/v2/tree/:user_id GET 取得檔案樹
/api/v2/tree/:user_id/node POST 建立節點
/api/v2/tree/:user_id/node/:node_id PUT/DELETE 更新/刪除節點
/api/v2/tree/:user_id/node/:node_id/move PUT 移動節點
/api/v2/tree/:user_id/node/:node_id/alias PATCH 更新別名

###顯示模式

  • tree - 樹狀顯示
  • list - 列表顯示
  • grid_sm - 小格狀顯示
  • grid_lg - 大格狀顯示

###範例

curl http://localhost:11438/api/v2/tree/demo?mode=tree
curl http://localhost:11438/api/v2/tree/demo?mode=list
