 ## Known Limitations and Deferred Work
 
 - **A patch replaces whole row configs** — profile overrides must restate every field a row keeps; there is no deep-merge layer.
-- **The Windows temp grant is the real temp directory** — `workspace-write` confines writes to the workspace plus the host temp area (the same backend-defined choice the Landlock rung makes); `read-only` grants nothing. See `@deepseek-ai/dsh-sandbox-windows-acl`.
+- **The Windows temp grant is a private per-session subdirectory** — `workspace-write` confines writes to the workspace plus the session's own temp subdirectory (`<temp>\dsh-<hash>`, TMP/TEMP rewritten for confined children); `read-only` grants nothing. See `@deepseek-ai/dsh-sandbox-windows-acl`.

 ## 已知限制与延期工作
 
 - **patch 会替换整行 `config`**：profile 覆盖必须重述该行需要保留的每个字段；不存在深度合并层。
-- **Windows 的临时目录授权是真实 temp 目录**——`workspace-write` 把写入限制在工作区与宿主 temp 区域（与 Landlock 档位相同的后端定义选择）；`read-only` 不授予任何写入。见 `@deepseek-ai/dsh-sandbox-windows-acl`。
+- **Windows 的临时目录授权是按会话的私有子目录**——`workspace-write` 把写入限制在工作区与会话自己的 temp 子目录（`<temp>\dsh-<hash>`，受限子进程的 TMP/TEMP 被改写）；`read-only` 不授予任何写入。见 `@deepseek-ai/dsh-sandbox-windows-acl`。
