私密保存一键完成,点击“打开”后右侧栏直接进入可编辑文档。 +6. 自由文档无编制/审核/批准限制,也不会进入 workflow。 +7. 共享前仅本人和代表本人的智能体可用;共享后同项目成员可见;撤回后立即失效。 +8. 其他用户无法通过列表、直接 API、搜索、摘要、智能体、导出或缓存推断私密内容。 +9. 所有导出、保存、共享、撤回与智能体读取均有不含正文的审计记录。 + +### 14.2

+## 十五、风险、取舍与后续演进 (Risks & Trade-offs) + +### 15.1 “复制到 Word 保留格式”不是绝对一致 + +不同目标应用对 Clipboard HTML 支持不同。设计目标是语义和主要样式保留,不承诺像素级一致;要求排版稳定时应引导用户下载 DOCX/PDF。 + +### 15.2 PDF 增加运行时复杂度 + +固定 Chromium worker 会增加镜像体积和运维成本,但能显著降低中文字体、分页和浏览器差异问题。将 PDF 独立开关、异步化,可以不拖慢复制、Markdown 和私密保存上线。 + +### 15.3 私密文档与现有 `DeliverableItem` 的兼容债务 + +短期可以通过适配器让右侧栏同时显示,长期应把“空间/可见性”和“治理模式/生命周期”拆成正交字段,避免 `private + drafting` 这种语义矛盾继续扩散。 + +### 15.4 管理员是否能看私密正文 + +本设计默认普通管理员不能通过产品 API 查看私密正文。运维取证若确需访问,应走独立的 break-glass 流程:双人审批、明确事由、短期授权、用户可见或合规可审计,而不是给 `ADMIN` 常态通配私密数据。 + +### 15.5 分享并不等于可撤回所有副本 + +取消共享可以阻断系统内后续访问、搜索和智能体检索,但无法删除成员已经合法下载或复制到外部系统的副本。产品文案必须真实表达这一边界。 + +### 15.6 后续扩展 + +- 多条回复勾选后合并为文档; +- 保存前让智能体“整理成正式文稿”,但需生成新回复并保留来源链; +- 组织品牌 DOCX/PDF 主题模板; +- 直接发送到 Google Docs/Drive、Microsoft 365 等连接器; +- 私密文档按用户显式授权共享给指定成员,而非整个项目; +- 受控工作流可通过“引用自由文档作为来源”的方式吸收内容,但必须由受控文档编制流程显式执行。 + +--- + +## 十六、最终设计原则 (Final Principles) + +1. **先判断内容是否适合成为文档,再提供导出按钮。** +2. **导出正文,不导出气泡 UI;导出快照,不导出变化中的流。** +3. **一个内容真源,多个格式适配器。** +4. **私密保存默认一步完成,共享必须用户主动确认。** +5. **自由文档和受控文档共用阅读入口,不共用治理状态机。** +6. **智能体的读取权限永远代表当前用户,而不是利用服务账号扩大权限。** +7. **隐私依靠确定性访问控制和数据血缘,不依靠模型“自觉保密”。** +8. **复杂性放在系统内部,界面只呈现复制、保存、下载和共享这些用户能理解的动作。** + +按照此规范实施后,用户可以把真正有办公价值的一次智能体回复快速带走或沉淀,同时不会把交互卡、系统状态和隐私边界一起“导出失控”。 diff --git a/go.mod b/go.mod index a7855513..e0c481a2 100644 --- a/go.mod +++ b/go.mod @@
