|

- The UI does not show “no output for this run”.
|
||||
- The same conversation is not used to start two different DSH live sessions.
|
||||
|
||||
Do not reuse a completed test `conversationId` for a new DSH live session. DSH detects a mismatch between the persisted session log and the new live session and reports `id collision`. Use **New conversation** for every fresh runtime test.
|
||||
You can continue chatting in the same MateClaw conversation. Each turn uses a fresh DSH process and runtime session ID to avoid persisted-log `id collision`. MateClaw supplies up to 40 recent completed user/assistant text messages from that conversation, within a 4096 estimated-token history budget. The current message is sent once and is not truncated by this history budget. Older history may be omitted and a boundary message may be marked `[truncated]`. Saved text history remains available after a backend restart; internal DSH tool state is not restored. Scheduled tasks do not replay conversation history.
|
||||
|
||||
To verify multi-turn context, send “My name is Alex”, then “What is my name?” in the same conversation. A new conversation must not inherit that information through this history mechanism.

- 页面不会显示“本次没有输出”。
|

- 同一个会话不会被并发启动两个 DSH live session。
|
||||
|

不要复用已经完成过的测试 `conversationId` 创建新的 DSH live session。DSH 会检测到磁盘上的 session 日志与新的 live session 不一致，并返回 `id collision`。请使用“新对话”创建新的会话。
|
||||
可以在同一个 MateClaw 会话中继续聊天。每轮仍使用新的 DSH 进程和运行时会话 ID，避免持久化日志的 `id collision`。MateClaw 会补入当前会话最近最多 40 条已完成的用户/助手文本消息，历史部分限制在估算 4096 token 内。本轮消息只发送一次，不受该历史预算截断；较旧历史可能被省略，边界消息可能带有 `[truncated]` 标记。后端重启后仍可读取已保存的文本历史，但不会恢复 DSH 内部工具状态。定时任务不回放会话历史。
|
||||
|
||||
验证多轮上下文：在同一会话先发送“我的名字叫小明”，再问“我叫什么名字？”。新建会话不应通过这项历史机制获得前一会话的信息。
