+## Commit Messages and Release Notes
+
+Release notes are derived in part from commit history, so commits for
+user-visible changes must record product intent rather than only the
+implementation mechanism.
+
+- Classify the commit by the user-visible behavior. Use `feat` only for a
+  capability users did not previously have. Use `fix` when restoring intended
+  behavior, removing inconsistency, or making two existing entry points reflect
+  the same underlying setting, even if the implementation adds new
+  synchronization logic.
+- Keep the subject concise, then add a commit body for non-trivial user-visible
+  changes. State the previous user-facing problem, the resulting behavior, and
+  the affected surface or workflow. Include permissions, migration,
+  compatibility, cost, data, preview-status, or other usage caveats when
+  relevant.
+- Describe the user outcome precisely. Do not promote an internal refactor,
+  synchronization mechanism, schema change, or newly added implementation code
+  to a product feature unless it creates a genuinely new user capability.
+- When a change is release-note worthy, include a short `Release note:` line in
+  the commit body written in user-facing language. Prefer a concrete usage
+  scenario and benefit over technical implementation terminology.
+- Treat commit messages as evidence, not as the sole source of truth. Before
+  drafting release notes, verify the diff and resulting behavior, correct any
+  inaccurate `feat` or `fix` classification, and include actionable usage
+  notes where the change affects defaults, synchronized settings, permissions,
+  resource usage, compatibility, or user data.
+
+Example:
+
+```text
+fix: unify project settings across channel entry points
+
+The top-left project settings and the project settings shown under messaging
+channels could present or save inconsistent values. They now edit the same
+project configuration for the project name, description, Runtime, and work
+mode.

-- 任务使用 `standard` 壳层，活动记录使用 `dashboard` 壳层。
-- “任务 / 活动”作为同级页面时使用 `PageTabs`。
-- 任务状态筛选使用 `SegmentedControl` 或筛选工具栏，不再模拟页签。
-- 活动记录保留审计字段和范围，支持独立容器横向滚动。
-- 批量停止、删除和清空历史遵循破坏性操作政策。
+- 使用 `dashboard` 壳层，并通过 `PageTabs` 提供“任务与会话 / 活动时间线 / 用量统计”三个同级视图。
+- 默认视图按“项目 → 任务或会话 → 活动详情”组织，项目范围持续可见，任务或会话详情可以折叠。
+- 任务或会话的综合状态以最近一次顶层请求对应的最终 Agent 结果为准；最终结果尚未产生时使用该请求的当前状态。中间工具或子专家的失败、取消和中断保留在活动详情中，但不得覆盖最终成功状态。
+- 活动时间线按项目分组、按任务或会话建立横向轨道，所有轨道共享同一执行顺序并按事件时间排列，以带身份名称的节点表达用户、主 Agent、子专家、工具、审批、状态和并行关系。节点内使用 `U / G / S / T / A` 拉丁字母简称，节点下显示完整身份或名称；选择节点后显示所属会话、不可变范围快照和完整详情。
+- 用量统计与活动记录分离，支持按项目、会话和模型切换统计维度，宽表格在独立容器内横向滚动。
+- 活动状态筛选使用 `SegmentedControl`，不与页面页签混合。清空历史遵循破坏性操作政策。

 ### 13.7 设置中心
 
 - 全页设置使用固定标题区、左侧分类导航和独立滚动的内容区。右上角关闭按钮是离开设置中心的稳定入口。
-- 全页设置标题区依靠留白与内容区分层，不在标题下方绘制贯穿整个工作区的分隔线；模态设置可以保留标题边界。
+- 左侧分类导航在宽屏使用 `220px`，中等窗口使用 `196px`，窄窗口转为横向滚动；纵向滚动条仅在内容溢出时占用右侧空间，不在左侧创建镜像预留，选项与左侧可见边界保持默认内距。分类标题使用正文级字号，分类说明使用辅助字号；右侧内容区在可用空间内流式伸缩，最大宽度使用 `standard` 壳层的 `960px`，不得以页面专属较窄宽度压缩表单。
+- 全页设置标题区与双栏内容使用共享 `--page-gutter`，标题、分类导航和内容区在同一页面边距基线上；标题继续使用标准 `PageHeader` 的底部分隔线与下内距。固定标题和双独立滚动区域不改变这些一级页面壳层规则；模态设置保留自身外框与标题边界。
 - 设置中心不显示全局操作页脚，避免重复关闭入口和没有功能意义的整宽分隔线。
 - 所有分类使用共享的 `SettingsCategoryHeader` 呈现分类标题、说明、错误与操作，不得在内容卡片内复制分类标题或创建页面专属操作栏。左侧分类名称与说明来自同一份分类定义，新增分类时不得分别维护导航和内容标题。
 - 当前分类存在“保存”或“测试”等未提交配置操作时，统一放在分类页头右侧；主保存操作在最右侧，测试等次操作排列在其左侧。
 - 自动生效、仅执行即时命令或自行管理编辑流程的分类不显示全局保存操作。窄窗口下操作区可以换行，但保存入口必须保持清晰可见。
 - 保存或测试成功统一进入应用通知视口，并按全局规则自动消失，不在分类页头或内容卡片中保留持久成功文案。加载、保存和测试错误显示在分类页头下方，并保留可处理的上下文。
+- Agent Runtime 分类页头的“保存设置”同时保存 Runtime 基础配置与 Runtime 原生定制，不在原生定制卡片内提供第二个保存入口。原生定制存在未保存更改时持续显示状态和撤销入口；切换设置分类或 Runtime 不丢弃草稿，关闭设置中心前必须先保存或撤销。
+- Agent Runtime 页面在低层程序与配置覆盖之外提供“能力与默认配置”区域。能力清单使用共享 `PageTabs`，按 Agents、Tools、Commands、Skills、MCP、Rules、Prompts、Resources、LSP、Formatters 和上下文 11 类单行滚动展示，一次只呈现当前分类的 `tabpanel`；清单只显示 Runtime 自有能力，不混入 GoodBuddy 分配的 Skills、临时 MCP 或 Continue 预设。Tools 必须独立于 Commands、LSP 和 Formatters，显示工具类型、来源及 Ask/Execute 可用性；清单状态必须区分完整、部分、不可用、仅连接和不支持，不能用进程连通性冒充清单可读。
+- “能力与默认配置”只显示一个模块标题，刷新入口位于该标题右侧，能力状态压缩为一行并排在默认 Agent 或 Continue 预设编辑器之前；不得再复制“Runtime 原生能力”等同义标题、说明或状态结论。刷新只更新能力快照，不覆盖未保存的原生定制草稿。
+- OpenCode 的默认 Agent 使用原生下拉选择；Continue 预设编辑器允许管理名称、说明、启用的 Rules 以及 Prompt 名称、说明和正文，并可展开查看原生 Rules 与启用预设 Rules 的最终合并顺序。持久启停仍使用共享 Switch，添加与删除使用明确按钮和可访问名称。
+- MCP 设置按“内置 MCP / 直连模型 / 自定义 MCP / 电脑控制”四个同级 `PageTabs` 组织。直连模型中的联网搜索与其他内置工具组使用一致的折叠卡片，展开后显示开关、测试状态、隐私说明和工具列表。内置 MCP 卡片与 Skills 一样提供持久启停和 Runtime 分配；直连模型、GoodBuddy 管理的 OpenCode 与 Continue 默认选中且可调整，DeepSeek Harness 必须以置灰、未选择和“暂不支持”文案持续显示，不能呈现为可保存的分配。魔法笔记 MCP 的自身启停与平台功能依赖分别显示，依赖未开启时保留用户配置并说明当前不会加载。
+- MCP Server 测试结果在同一展开卡片中分组显示 Tools、Prompts 和 Resources 的支持状态、数量与有界元数据；Prompt 参数标明必填项，Resource 只显示 URI、名称、类型和说明，不读取或渲染 Resource 内容。

+本文定义 DeepSeek Harness 在 GoodBuddy 中的架构边界、协议、执行策略、插件市场、界面、打包和验收要求。实现必须继续遵守 GoodBuddy 已有的 Main 进程安全边界、Ask/Execute 语义、取消、超时、有界输出和资源回收约定。
 
 ## 2. 摘要
 
-DeepSeek Harness 的底层库使用 Cordis 组合服务。GoodBuddy 不采用官方产品 profile、插件安装或市场机制，也不让用户配置覆盖安全服务，而是增加一个实验性的第三 Runtime，并完全自行维护 Host、控制协议、生命周期和兼容层。上游 DSH 包只是精确锁定并逐次审查的实现依赖，不构成 GoodBuddy 对 DSH 插件 ABI、插件目录或产品路线的承诺。
+DeepSeek Harness 的底层库使用 Cordis 组合服务。GoodBuddy 不采用官方产品 profile，也不允许用户配置覆盖内部 Host 或控制服务；GoodBuddy 自行维护 Host、控制协议和生命周期，同时提供一个由 Main 管理、默认关闭的 npm 插件市场。用户显式开启后，市场只搜索带精确 `dsh-plugin` 关键字的公共 npm 包，不代表 GoodBuddy 审核、推荐或承诺兼容这些包。
 
-GoodBuddy 并不迫切于把该能力做成 DSH 插件或进入插件市场。当前优先级是向用户提供稳定、可靠、可审计且可完整回收的 Runtime；只有未来真实用户需求和成熟度证明插件化确有价值时，才重新评估该形态。
+用户明确安装并启用的插件以当前用户权限运行。Ask/Execute 只控制模型经过 `tools/execute` 发起的工具调用：Ask 只允许 Host 中真实注册的 `read`、`skill` 和 Main 管理的 Web Search/Fetch 代理，Execute 放行 Host 中全部已注册工具。插件不能用同名工具冒充 Ask 允许项。插件安装脚本和初始化代码不属于模型工具调用，不能由 Ask 限制，因此界面在安装前必须明确确认这一边界。

    - 增加 GoodBuddy 所需的能力握手、每轮权限准备、会话释放、工具事件、推理、用量和安全凭据请求扩展。

 ### 10.1 模式映射
 
-| GoodBuddy 模式 | DSH 文件模式 | DSH 权限策略 | 行为 |
-| --- | --- | --- | --- |
-| Ask | `read-only` | `never` | 允许受控读取，不允许写入，不允许升级 |
-| Execute | `workspace-write` | `ask` | 允许工作区与受控临时目录写入；权限请求由 Main 自动单次授权，不弹出交互审批 |
-
-`danger-full-access` 只能作为某个已被沙箱拒绝的完全相同操作的一次性、更宽重试。Main 仅对该次重试自动返回 `allow-once`；它不能保存为默认值、复用于后续操作，或通过“始终允许”返回。
+| GoodBuddy 模式 | Host 内置与插件工具 | Main Web Search/Fetch | GoodBuddy 自定义 MCP | 行为 |
+| --- | --- | --- | --- | --- |
+| Ask | 只允许 Host Registry 中真实注册的 `read` 与 `skill`；其他 Host/插件工具一律拒绝 | 能力启用时注册 Main 的精确代理对象，无逐次审批 | 不注册 | 模型工具调用保持只读 |
+| Execute | 放行 Host 中全部已注册的内置与插件工具 | 能力启用时注册 Main 代理 | 按分配注册并经过既有 RuntimeAuthorizer | 不增加插件权限层，以当前用户权限运行 |
 
 ### 10.2 Ask 模式
 
-- Main 即使收到权限请求也固定拒绝。
-- Harness Control Plane 禁止 `sandbox_permissions` 升级。
-- 文件写入和 Shell 写入都由 DSH 共享 Sandbox Policy 强制拒绝。
-- 只读不等于无限输出，读取仍受路径、字节和工具结果上限控制。
-- 首版不向 Ask 暴露 GoodBuddy 的可变数据工具。
+- Harness Control Plane 在 `tools/execute` 分发边界识别当前 Session 和在途请求。
+- 采用所有权感知的只读允许列表，只接受 Registry 中真实的 `read`、`skill` 和 Main 注册的 Web 代理对象；`write`、`edit`、Shell、MCP 及任意新插件工具默认拒绝。只比较工具名不足以授权，插件注册同名工具仍会被拒绝。
+- Ask 不注册 Main 代理的 MCP 工具。
+- Web Search/Fetch 的凭据、传输与结果限制保留在 Main；Utility 只看到有界 schema 和结果。
+- 只读不等于无限输出，读取仍受字节和工具结果上限控制。
+- 插件安装脚本和 Cordis 初始化生命周期不经过 `tools/execute`。Ask 不能把已启用第三方代码变成沙箱，也不能保证第三方代码没有启动副作用。
 
 ### 10.3 Execute 模式
 
-- 工作区根来自 Session 创建时的规范化绝对路径。
-- 工具不能自行更换工作区根。
-- 工作区内操作按 DSH `workspace-write` 执行。
-- 只有真实沙箱拒绝后的同一操作，才可请求一次升级。
-- Main 不调用 `ToolApprovalBroker`，而是对当前 Execute 请求自动返回 `allow-once`；界面不进入等待审批状态，也不弹出审批对话框。
+- 工作区来自 Session 创建时的规范化绝对路径，并作为文件与命令工具的默认工作目录。
+- DSH 本地 Filesystem、Bash 或 PowerShell Provider 直接使用 GoodBuddy 客户端当前用户的 OS 权限。
+- 工作区不是 containment 边界；绝对路径和命令可访问当前用户本来有权访问的主机资源。
+- 已启用插件注册的工具与内置工具使用同一分发路径；GoodBuddy 不增加插件权限矩阵或逐工具确认。
+- Main 代理的 MCP 工具继续执行分配、schema、活动请求、模式和 RuntimeAuthorizer 校验。
 - 所有工具调用仍作为活动事件记录；Ask 和 delegation 路径继续固定拒绝。
-- Harness Control Plane 不接受 `allow_always`，也不把未知结果解释为允许。
 
-### 10.4 沙箱可用性
+### 10.4 Runtime OS 沙箱
 
-- `strict`：要求完整强制执行。仅有 `partial` 或无 Runner 时 Runtime 不可用。
-- `auto`：允许官方报告的 `full` 或 `partial`，但必须在状态卡显示实际强制程度。
-- `off`：不允许 Harness 退化到无限制工具执行。首版将 Execute 标记为不可用，Ask 仍只能在可强制只读时运行。
