 ## Known Limitations and Deferred Work
 
-- **Semantic intent remains model judgment** — execution can prove direct human provenance, not whether a request is substantial enough to merit a goal.
+- **Semantic intent remains model judgment** — execution can prove that the current turn contains a direct human message, not whether the request is substantial enough to merit a goal.
 - **Same-condition blocking remains model judgment** — the runtime enforces distinct admitted-round count, not semantic equivalence of obstacles; an independent evaluator is deferred.
 - **No scheduling or direct human rendering** — these tools mutate state only; the same-session driver and [`dsh-command-goal`](../command-goal/README.md) are independent consumers of the same domain.
 - **Goal-round authority requires a driver** — the autonomous `complete`/`blocked` path is dormant unless a continuation driver admits goal-sourced user turns; mounting this tool package alone does not create them.

 ## 已知限制与暂缓事项
 
-- **语义意图仍由模型判断**：执行只能证明人类直接来源，无法证明请求是否足够重大而值得创建 goal。
+- **语义意图仍由模型判断**：执行只能证明当前轮次包含一条人类直接发送的消息，无法证明请求是否足够重大而值得创建 goal。
 - **阻塞条件是否相同仍由模型判断**：运行时强制统计互不重复的已准入 Goal Round，而不判断障碍在语义上是否等价；独立评估器的实现暂缓。
 - **不负责调度或直接面向人类呈现**：这些工具只变更状态；同会话驱动器与 [`dsh-command-goal`](../command-goal/README.md) 是同一领域的独立消费方。
 - **Goal Round 权限需要驱动器**：除非续行驱动器准入 goal 来源的用户轮次，否则自主 `complete`／`blocked` 路径不会启用；只挂载这个包不会创建这些轮次。
