+- [ ] **本地录音与离线转写**（开发中）：采集麦克风音频并使用已选择的本地模型离线转写，补齐取消、资源释放和 Electron 打包验证。
+- [x] **版本检查**：仅检查固定官方 Release 和当前平台清单，不自动下载或安装。
+- [x] **内网兼容模式**：默认开启；允许应用内 HTTP 与无效、自签名或过期的 HTTPS 证书，关闭后恢复严格地址和证书校验。
+
+### 开放接口、团队协作与远程执行
+
+- [x] **远程任务委派**：仅在用户显式配置端点和令牌后启用，按全局内网兼容模式使用 HTTP(S)，结果进入持久化发件箱。
+- [ ] **Headless Runtime API 与受控分享**（规划中）：提供本机优先的任务提交、流式事件、状态和成果 API，并使用带范围、有效期、限流和撤销能力的访问令牌。
+- [ ] **GoodBuddy Team Hub**（规划中）：以可选独立服务提供组织、成员、RBAC、项目共享、远程 Agent 注册、策略下发和租户级审计。
+- [ ] **多云远程沙盒 Agent**（规划中）：管理阿里云 ECS、腾讯云 CVM、AWS EC2，并通过 SSH + Agent 提供专用自主沙盒。
+
+## 重大功能规划
+
+### Agent 框架与协作能力
+
+参考 MesaLogo 中已经存在或正在验证的 Action Space、受控工作流、Subagent、MCP 管理、批量实验和运行观测思路，GoodBuddy 计划在现有本地优先架构上逐步增加以下能力。这里列出的项目均为 GoodBuddy 自身规划，不表示 MesaLogo 的原型或路线图已在 GoodBuddy 中提供。
+
+- [ ] **项目 Agent Space 与策略包**：不新增与 Project 重复的一级概念，而是在现有 Project 中统一角色、知识集合、Skills/MCP、默认模型、变量、工作模式、审批策略、预算和超时，并支持模板化复用。
+- [ ] **统一 Run Graph**：先统一父子任务、节点、模型调用、知识命中、工具审批、用量、成果和取消事件，作为工作流、可执行 Subagent、批量实验和回放的共同基础。
+- [ ] **MCP Server Control Plane**：由 Main 进程统一管理 `stdio`、HTTP 和 SSE Server，执行连接验证、健康检查、重连、Schema 缓存、环境变量白名单、资源配额、项目或任务隔离以及逐次审批和审计。
+- [ ] **可视化受控工作流**：首版只支持开始、Agent/Subagent、知识、声明式条件、审批、成果和结束节点；流程需要版本化、校验、取消和恢复。任意网络请求或执行节点不得绕过现有 Runtime 与审批边界。
+- [ ] **可执行 Subagent**：保留现有专家默认只读语义，只在显式 Execute 委派中允许受控工具，限制深度、并行数、Token、时间、成果范围和父子权限继承。
+- [ ] **批量运行与对比实验室**：对模型、Prompt、角色和工作流版本进行参数扫描与 A/B 对比，展示质量评分、耗时、Token、费用、失败率和成果差异。
+- [ ] **时态记忆与事实冲突检测**：在现有知识图谱和证据链上增加事实有效期、当前状态、过期与矛盾检测、核验流程及来源回溯。
+- [ ] **Headless Runtime API**：作为可选、本机默认仅监听 loopback 的服务，提供任务提交、流式事件、状态和成果下载；访问令牌必须具有 scope、有效期、速率限制、项目限制和撤销能力。
+- [ ] **GoodBuddy Team Hub**：作为独立可选服务提供组织、成员、RBAC、项目共享、远程 Agent 注册、策略下发和租户级审计，不把 Electron Renderer 或云端服务改造成用户凭据持有者。
+
+安全边界保持不变：Ask/Plan 必须在 Runtime 边界只读；Execute、MCP、网络和 Subagent 工具均经过 Main 进程审批与审计；不得照搬进程内脚本执行、任意 URL 请求、仅以 `created_by` 模拟多租户或共享无隔离 MCP 会话等做法。
+
+### 知识工作空间与魔法笔记
+
+- [ ] **魔法笔记 / Magic Notes**：建设本地优先的结构化笔记工作空间，支持将用户选中的对话片段、知识条目、文档摘录和网页摘录收集为可编辑笔记，并持续保留来源、位置和引用关系。
+- [ ] **受控 AI 笔记操作**：提供总结、改写、续写、整理和关联知识等显式操作；操作结果先进入笔记或待确认变更，不静默回写或修改来源知识。
+
+### 多云远程沙盒 Agent
+
+GoodBuddy 将支持把专用云主机作为模型可自主使用的远程沙盒。首批计划接入：
+
+- 阿里云 ECS
+- 腾讯云 CVM
+- AWS EC2
+- 其他可通过 SSH 管理的 Linux 主机
+
+计划包含以下能力：
+
+- [ ] **云主机控制面**：通过云厂商官方 API 发现、创建、启动、停止和删除实例，创建前展示地域、规格、镜像、网络和费用相关配置。
+- [ ] **SSH + GoodBuddy Agent**：校验 SSH 主机指纹后，以专用非 root 账户安装、升级和配对 Agent，不要求模型接触 SSH 私钥。
+- [ ] **沙盒内自主执行**：用户可将明确指定的专用实例设为自主沙盒。模型在该沙盒的工作目录内连续执行命令、修改文件和运行任务，不逐条请求审批。
+- [ ] **控制面与执行面隔离**：云 API 密钥、临时凭据和 SSH 私钥只保存在 Main 进程的系统加密存储中，不下发给 Renderer、模型或远程任务。模型的自主权限不包含云账户管理权限。
+- [ ] **高风险操作保护**：删除实例、修改安全组或网络、扩缩容和其他可能产生额外费用或数据损失的控制面操作仍需单独确认。
+- [ ] **可观测与可恢复**：实时回传心跳、日志、进度、退出状态和有界成果文件，支持取消、超时、断线重连、失败诊断和完整活动审计。
+- [ ] **跨云一致体验**：使用统一的实例状态、Agent 能力和任务协议；阿里云、腾讯云、AWS 的差异由独立 Provider Adapter 隔离。
