# 聊天历史导航
|
|
|
|
聊天历史导航负责长会话的连续滚动、窗口化渲染，以及后续的对话 minimap。第一阶段先取消向上滚动时每次增加 80 条消息的产品限制，保留已有的消息窗口化机制；第二阶段再评估 minimap。

## 文档导航
|
|
|
|
| 文档 | 权威职责 |
|
|
| --- | --- |
|
|
| [产品需求](./prd.md) | 用户问题、范围、验收和非目标 |
|
|
| [技术设计与测试计划](./technical-design.md) | 当前实现边界、实验分组、性能指标和执行步骤 |
|
|
| [实施进度](./progress.md) | 已验证事实、命令、结果和遗留问题 |
|
|
|
|
## 术语
|
|
|
|
- **历史窗口**：允许滚动访问的消息范围。第一阶段扩大为当前已加载会话的全部消息。
|
|
- **DOM 窗口**：实际挂载消息组件的范围。继续由消息高度估算和最多约 60 条挂载消息控制。
|
|
- **minimap**：对话右侧的轻量纵向全局导航概览，不等于完整渲染所有消息。
