### 派生关系

本项目的协议层是上述项目在 DeepSeek Harness 上的重写。以下部分沿用其契约与实现逻辑：

- `/alpha/generate` 请求信封结构（`config` / `params` 形状）
- 逐行 JSON（LDJSON）流的事件词汇与 `StreamChunk` 映射规则，包括
  `-end` 事件不带内容与 block id 时的累积处理、`finish-step` 与 `finish` 的用量去重
- 工具调用的转换规则：可选参数在传输层表示为可空（`anyOf` + `null`）、回程丢弃这些 null
- 工具调用 id 的规整规则（复合 id 取头部、长度上限）
- 图片处理契约：单图重编码上限、内联 base64 总量预算、`IMAGE_OFFLOAD_REQUIRED` 语义、
  已 offload 的图片以占位文本替代、纯图片 user turn 需延迟到工具轮之后
- 纯文本模型名单（来源为官方 CLI 自身的分类）
- 网关错误体与流内错误事件的解析方式
