 前端提供三种整体权限模式：“请求批准”只执行 OpenCode 明确允许的白名单，其他权限请求逐次交给用户确认；“自动批准”额外自动放行低风险业务工具、skill，以及真实路径位于工作区安全子树且不涉及 `.env`、`data/`、`logs/` 的 glob/grep；工作区根目录的宽泛搜索仍需确认。“始终允许”自动放行当前对话中所有未被 OpenCode 明确禁止的权限请求。自动放行统一使用单次批准，切换整体模式后立即恢复对应策略，不会写入持久授权。
 
-单次权限请求支持“允许一次”“保存授权”和“拒绝”。“保存授权”使用 OpenCode 的 `always` 回复，仅保存 OpenCode 为本次请求建议的权限范围，并只在当前 OpenCode 会话内生效。外部目录以及 `.env`、`data/`、`logs/` 路径仍由静态配置明确禁止，三种整体模式都不能绕过这些拒绝规则。
+单次权限请求支持“允许一次”“保存授权”和“拒绝”。“保存授权”使用 OpenCode 的 `always` 回复，仅保存 OpenCode 为本次请求建议的权限范围，并只在当前 OpenCode 会话内生效。任意外部目录默认仍由静态配置禁止；`.env` 的直接访问以及通过结构化读写工具访问普通 `data/`、`logs/` 路径仍保持禁止。真实聊天会话使用 `data/conversation-workspaces/<随机目录>/` 作为独立工作目录，结果导入只能读取当前对话目录。普通 `rm <文件>` 仍可审批执行，常见的 `rm -rf`/`rm -fr` 递归强制删除形式会被静态拒绝。
 
-`store_render_ref` 只会从 `RESULT_REF_IMPORT_DIR`（默认 `./data/result-imports`）导入包装格式 JSON。文件必须包含 `metadata`、`location.file_path` 和 `data`，且真实路径不能越出导入目录；单文件默认上限为 128 MiB，成功导入后源包装文件会被删除。
+`store_render_ref` 只会从当前对话绑定的工作目录导入包装格式 JSON；工作区根目录固定为项目内的 `./data/conversation-workspaces`，以确保 OpenCode 能继续发现项目配置和工具。文件必须包含 `metadata`、`location.file_path` 和 `data`，且真实路径不能越出当前对话目录；单文件默认上限为 128 MiB，成功导入后只删除这一份源包装文件。升级前已经存在的会话没有独立工作目录，需要新建对话后才能使用该导入能力。
 
 CLI 桥接层对 stdout 设置独立的 128 MiB 硬上限（`MAX_CLI_OUTPUT_BYTES`）；stderr 最多保留 256 KiB（`MAX_CLI_STDERR_BYTES`），超出后截断但不会终止 CLI。`MAX_INLINE_RESULT_BYTES`（默认 12000 字节）只控制 OpenCode 的内联阈值，较大结果由 OpenCode 写入标准 `tool-output` 目录。Agent 启动时及后续定期清理其中超过 `RESULT_REF_TTL_HOURS`（默认 7 天）的 `tool_*` 文件。
