## 1. `@deepseek-ai/dsh-session-persistence-jsonl`（DeepSeek Harness）

| 项 | 值 |
|---|---|
| 上游项目 | DeepSeek Harness (DSH) |
| 上游仓库 | <https://github.com/deepseek-ai/deepseek-harness> |
| 涉及的包 | `@deepseek-ai/dsh-session-persistence-jsonl` |
| 使用位置 | 本仓库 `src/zstd.mjs` 的 `scanZstdFrames()` |
| 许可证 | MIT，`Copyright (c) 2026 DeepSeek` |

本项目的 `src/zstd.mjs` 中，Zstandard 多帧日志的**帧边界扫描逻辑**改写自该包的
`scanZstdFrames()` 实现（DSH 的 `session.*.jsonl.zstd` 是追加写入的多帧 zstd，
必须按帧边界切分后逐帧解压）。上游实现与本项目实现同构，其版权声明与许可声明
按 MIT 要求保留如下。

`src/zstd.mjs` in this project adapts the Zstandard multi-frame **frame-boundary scanning
logic** from that package's `scanZstdFrames()` implementation. The upstream copyright and
permission notice are retained below, as required by the MIT license.
