+### Current file policy and indirect consumer
 
 #### What the model sees
 
-Nothing directly. Through `@deepseek-ai/dsh-tool-pty`, the model may receive bounded MOTD, send deltas, scrollback pages, readiness reasons, and cleanup errors.
+This backend contributes the terminal family to the owner-rendered `sandbox:policy` section. Through `@deepseek-ai/dsh-tool-pty` or another PTY consumer, the model may also receive bounded MOTD, send deltas, scrollback pages, readiness reasons, and cleanup errors.
 
 #### Token effect
 
-None until a consumer returns bounded backend output. Retained PTY scrollback is not placed in model history by this package.
+The current-policy clause is present while this backend is mounted. Retained PTY scrollback is not placed in model history until a consumer returns bounded output.
 
 #### KV Cache effect
 
-No direct invalidation; the consumer owns prompts, schemas, and appended results.
+A standing-policy or terminal-family change updates the owner-rendered request prefix; consumer results remain append-only.

 #### 模型看到的内容
 
-没有直接可见内容。模型通过 `@deepseek-ai/dsh-tool-pty` 可能收到有界的 MOTD、发送增量、scrollback 页、就绪原因和清理错误。
+该后端会向归属方渲染的 `sandbox:policy` 段落贡献终端家族。模型通过 `@deepseek-ai/dsh-tool-pty` 或其他 PTY 消费方还可能收到有界的 MOTD、发送增量、scrollback 页、就绪原因和清理错误。
 
 #### Token 影响
 
-消费方返回有界的后端输出前没有影响。此包（package）不会把保留的 PTY scrollback 放入模型历史。
+装载该后端期间，当前策略子句会一直存在。消费方返回有界输出前，保留的 PTY scrollback 不会进入模型历史。
 
 #### KV Cache 影响
 
-不会直接使 KV Cache 失效；提示词、schema 与追加结果由消费方负责。
+常驻策略或终端家族发生变化时，归属方渲染的请求前缀会更新；消费方结果保持仅追加。
