+# 远程消息通道项目与微信 ClawBot 集成 PRD
+
+## 文档信息
+
+| 项目 | 内容 |
+| --- | --- |
+| 状态 | 已实施，待真实微信账号联调 |
+| 版本 | 1.0 |
+| 日期 | 2026-08-09 |
+| 适用产品 | GoodBuddy 桌面端 |
+| 首期范围 | 微信 ClawBot、企业微信、钉钉的通道项目；微信文字 Ask 与 Execute |
+
+## 1. 背景
+
+GoodBuddy 已支持企业微信和钉钉远程消息通道，但目前通道仅存在于设置页和后台服务中。远程消息进入任务系统后，用户无法在项目与会话导航中持续、明确地识别：
+
+1. 消息来自哪个平台。
+2. 当前正在与哪个发送者或群聊对话。
+3. 远程执行任务使用哪个工作目录。
+4. 执行请求、审批、工具调用和结果归属于哪个范围。
+
+GoodBuddy 同时计划接入腾讯官方微信 ClawBot。微信 ClawBot 使用扫码授权，不使用 App ID 或 Secret，并需要在本机持续运行通信服务。微信消息既要支持只读对话，也要支持受控执行。
+
+为避免把通道来源、发送者身份和执行范围混在一起，本功能使用“通道项目 + 远程会话”的两级结构：
+
+- 通道项目标识平台并确定默认工作目录和默认模式。
+- 远程会话标识具体发送者或群聊。
+- 消息记录具体发送者和本次实际使用的模式。
+- 任务与活动记录执行、审批、工具调用和结果。
+
+## 2. 已确认的产品决策
+
+1. 微信 ClawBot、企业微信、钉钉分别对应一个系统管理的通道项目。
+2. 三个通道项目在通道设置服务初始化时幂等创建，不等待用户完成连接配置。
+3. Renderer 不直接创建通道项目。Main 进程保证项目存在，设置卡片首次展示时即可引用对应项目。
+4. 通道项目默认根目录为当前操作系统用户目录。
+5. 同一通道中的不同私聊用户或群聊分别建立独立远程会话。
+6. 微信 ClawBot 首期只支持个人微信私聊和文字消息。
+7. 微信卡片可以配置默认“对话”或“执行”模式。
+8. “对话”映射为 GoodBuddy `Ask`；“执行”映射为 `Execute`。
+9. 微信 Execute 请求必须先在本机进行请求级确认，不能通过同一个微信通道批准自身。
+10. 请求级确认通过后，任务仍受现有 Runtime、沙箱、能力开关、工具审批和活动审计约束。
+11. 停用或断开通道不得删除通道项目、远程会话、任务、活动或成果历史。
+12. 通道项目由系统管理，用户不能永久删除；用户可以修改其工作目录和默认模式。
+
+## 3. 目标
+
+### 3.1 用户目标
+
+- 在项目切换器中一眼识别微信、企业微信和钉钉来源。
+- 在通道项目中区分不同发送者和群聊。
+- 在设置卡片中完成连接、启停、模式和工作目录配置。
+- 通过微信进行只读问答或发起受控执行任务。
+- 在本机明确确认远程 Execute 请求，并查看完整执行记录。
+- 保留通道关闭前后的历史上下文和审计记录。
+
+### 3.2 产品目标
+
+- 将远程通道纳入 GoodBuddy 现有 Project、Conversation、Task、Activity 和 Artifact 信息架构。
+- 复用现有 ChannelService 的白名单、去重、并发、取消、输出限制和错误脱敏能力。
+- 保持 Electron Main、Preload、Renderer 和不可信子进程之间的安全边界。
+- 为后续图片、语音、文件、多账号和更多通道提供稳定扩展点。
+
+## 4. 非目标
+
+首期不包含：
+
+- 微信群聊。
+- 微信图片、语音、视频和文件收发。
+- 多个个人微信账号同时绑定。
+- 通过微信批准 Execute 请求或工具调用。
+- 无需本机确认的远程自主执行。
+- 主动群发、营销消息或任意联系人发现。
+- 将微信会话自动合并进普通本地会话。
+- 删除或迁移现有企业微信、钉钉历史数据。
+- 把完整 OpenClaw Runtime 打包进 GoodBuddy。
+
+## 5. 信息架构
+
+### 5.1 项目分组
+
+项目选择器增加“远程通道”分组：
+
+```text
+普通项目
+├─ 默认项目
+└─ 用户创建的其他项目
+
+远程通道
+├─ 微信 ClawBot
+├─ 企业微信
+└─ 钉钉
+```
+
+每个通道项目持续显示连接状态：
+
+- 未配置
+- 已停用
+- 正在连接
+- 等待扫码
+- 已连接
+- 连接失败
+
+通道状态不得只通过颜色表达。
+
+### 5.2 项目、会话和消息关系
+
+```text
+通道项目
+  └─ 远程会话
+       └─ 消息
+            └─ 可选任务 / 活动 / 成果
+```
+
+职责划分：
+
+| 层级 | 负责内容 |
+| --- | --- |
+| 通道项目 | 平台、连接状态、默认根目录、默认模式 |
+| 远程会话 | 平台账号、私聊用户或群聊、连续上下文 |
+| 消息 | 具体发送者、本次实际模式、正文、时间和处理状态 |
+| 任务与活动 | 请求级确认、Runtime、工具审批、执行结果和错误 |
+
+### 5.3 会话命名
+
+- 微信 ClawBot：优先使用已绑定用户昵称；不可用时显示“我的微信”。
+- 企业微信私聊：优先使用平台显示名，否则显示脱敏发送者 ID。
+- 钉钉私聊：优先使用平台显示名，否则显示脱敏发送者 ID。
+- 群聊：使用群名称；每条消息仍显示具体发送者。
+- 不得把原始 Token、上下文令牌或完整敏感标识作为会话标题。
+
+## 6. 通道项目生命周期
+
+### 6.1 自动创建
+
+应用初始化通道设置服务时，Main 进程执行 `ensureChannelProjects()`：
+
+1. 按稳定通道标识查找 `weixin`、`wecom`、`dingtalk` 对应项目。
+2. 缺失时创建系统管理项目。
+3. 已存在时复用，不重复创建。
+4. 如果存在同名普通项目，不得按名称占用或修改该项目。
+5. 创建失败时保留其他通道可用，并在设置快照中返回有界错误。
+
+默认值：
+
+| 通道 | 项目名称 | 根目录 | 默认模式 |
+| --- | --- | --- | --- |
+| `weixin` | 微信 ClawBot | 用户目录 | Ask |
+| `wecom` | 企业微信 | 用户目录 | Ask |
+| `dingtalk` | 钉钉 | 用户目录 | Ask |
+
+### 6.2 系统管理约束
+
+- 通道项目不能从普通项目危险区永久删除。
+- 停用通道不归档项目。
+- 断开微信不删除项目和历史。
+- 数据迁移或异常导致项目缺失时，下次初始化自动修复。
+- 用户可以修改项目根目录、描述和默认模式。
+- 项目名称首期由系统管理，避免来源名称被改到不可识别；后续如允许自定义，必须持续显示通道徽标。
+
+### 6.3 默认用户目录
+
+通道项目默认使用操作系统用户目录。设置卡片必须显示完整目录，并在首次启用 Execute 时明确说明该范围可能包含桌面、下载、文档和其他私人文件。
+
+如果根目录不存在、不可访问或不是目录：
+
+- Ask 仍可在不读取本地文件的边界内工作。
+- Execute 不得启动。
+- 设置卡片显示就近错误和“选择目录”操作。
+
+## 7. 设置页产品需求
+
+### 7.1 导航
+
+设置页标签由“企业通信”改为：
+
+- 标题：消息通道
+- 说明：微信 ClawBot、企业微信与钉钉
+
+### 7.2 卡片通用结构
+
+每个通道卡片包含：
+
+1. 通道名称和连接状态。
+2. 启用开关。
+3. 默认处理模式。
+4. 默认工作目录。
+5. 对应通道项目及“打开”操作。
+6. 平台特有的连接配置。
+7. 最近错误或最近连接时间。
+
+示意：
+
+```text
+微信 ClawBot                              已连接
+
+已绑定账号：微信用户 ****8a3f
+最近收到消息：今天 14:32
+
+启用微信通道                              [开关]
+
+默认处理模式
+[ 对话 ] [ 执行 ]
+
+默认工作目录
+C:\Users\用户名                           [选择目录]
+
+通道项目
+微信 ClawBot                              [打开]
+
+[断开连接]
+```
+
+“对话 / 执行”是互斥状态，应使用语义化分段控件，不使用两个独立复选框。
+
+### 7.3 模式说明
+
+- 对话：只读回答，不调用工具或修改内容。
+- 执行：允许发起工具任务，但需要本机请求级确认，并继续遵守现有审批规则。
+
+默认模式从 Ask 切换到 Execute 时显示风险确认：
+
+```text
+允许此通道默认发起执行任务？
+
+远程消息可能要求 GoodBuddy 读取或修改默认工作目录中的内容。
+每个执行请求仍需要在这台电脑上确认。
+
+默认工作目录：
+C:\Users\用户名
+
+[取消] [确认启用]
+```
+
+### 7.4 微信扫码绑定
+
+未绑定时显示“绑定个人微信”。扫码对话框包含：
+
+- 本地渲染的二维码。
+- 扫码和手机确认步骤。
+- 二维码剩余有效时间。
+- 刷新和取消操作。
+- 等待扫码、已扫描、需要验证码、已连接、已过期和失败状态。
+
+二维码过期时不得继续接受旧扫码结果。
+
+需要配对数字时，在同一对话框中显示验证码输入。验证码不得写入日志或持久化。
+
+### 7.5 企业微信和钉钉
+
+企业微信和钉钉继续使用现有凭据表单、环境变量只读覆盖和连接测试，但增加：
+
+- 通道项目显示。
+- 默认处理模式。
+- 默认工作目录。
+- 打开通道项目。
+
+现有发送者白名单和群聊提及设置继续有效。
+
+## 8. 远程会话需求
+
+### 8.1 会话创建与复用
+
+收到合法消息后，根据以下稳定键查找会话：
+
+```text
+channel + accountId + externalConversationId
+```
+
+- 未找到时，在对应通道项目下创建远程会话。
+- 已找到时继续使用现有会话。
+- 微信私聊的 `externalConversationId` 首期可由绑定账号和发送者稳定标识组成。
+- 不得仅按显示名称匹配会话。
+- 消息重试不得创建重复会话或重复任务。
+
+### 8.2 新建上下文
+
+首期支持以下方式创建新上下文：
+
+- 微信发送 `/new`。
+- GoodBuddy 会话页面点击“新建远程会话”。
+
+新会话仍属于相同通道项目。旧会话保留并可搜索。
+
+### 8.3 展示
+
+最近对话和聊天标题区显示：
+
+- 通道图标和名称。
+- 私聊用户或群聊名称。
+- 当前连接状态。
+- 默认模式。
+- 未读状态。
+
+每条远程消息记录实际模式：
+
+- Ask
+- Execute
+- 等待本机确认
+- 已拒绝
+- 执行中
+- 等待工具审批
+- 已完成
+- 失败
+
+收到普通远程消息时不得强制切换当前页面。应增加未读标记和全局通知。Execute 请求等待确认时显示高优先级全局入口。
+
+## 9. Ask 与 Execute
+
+### 9.1 模式解析
+
+每条消息的模式按以下优先级确定：
+
+1. 显式 `/ask` 或“对话：”前缀使用 Ask。
+2. 显式 `/execute`、`/exec` 或“执行：”前缀使用 Execute。
+3. 没有前缀时使用通道项目的默认模式。
+
+前缀仅用于选择模式，不进入发送给模型的正文。
+
+### 9.2 Ask
+
+- 在 Runtime 边界保持只读。
+- 不提供工具授权回调，或所有工具请求返回拒绝。
+- 不修改文件、数据库、系统状态或远程状态。
+- 结果以有界文字返回原通道并写入远程会话。
+
+### 9.3 Execute 请求级确认
+
+Execute 消息通过身份、长度、去重和并发检查后：
+
+1. 创建状态为“等待远程执行确认”的任务。
+2. 向微信回复“执行请求已发送到电脑，等待确认”。
+3. 显示桌面通知和 GoodBuddy 全局确认对话框。
+4. 用户在 120 秒内选择“拒绝”或“仅允许此任务”。
+5. 超时、应用退出、通道停用或会话失效均自动拒绝。
+6. 确认通过后才调用 Execute Runtime。
+
+请求级确认不得提供：
+
+- 此会话永久允许。
+- 此发送者永久允许。
+- 微信内确认。
+- 自动确认。
+
+确认内容必须显示：
+
+- 通道。
+- 发送者。
+- 完整有界任务正文。
+- 通道项目。
+- 默认工作目录。
+- 超时时间。
+- “具体工具仍受现有控制”的说明。
+
+### 9.4 工具控制
+
+请求级确认不是工具授权替代品：
+
+- OpenCode、Continue 和直连模型仍执行各自现有能力检查。
+- Runtime 沙箱模式继续有效。
+- 禁止策略继续拒绝工具。
+- 需要逐工具审批的 Runtime 继续发送本机审批事件。
+- 远程来源不得扩大 `session` 或 `permanent` 授权范围。
+- 任何工具结果都进入现有任务和活动审计。
+
+### 9.5 结果回传
+
+- 成功：回传有界文字结果。
+- 失败：回传经过脱敏、长度受限的用户可处理错误。
+- 取消：回传“任务已取消”。
+- 拒绝或超时：回传“电脑端未允许此次执行”。
+- 结果投递失败时保留发件箱记录并显示通道错误，不重复执行任务。
+
+## 10. 微信 ClawBot 通信架构
+
+### 10.1 进程边界
+
+微信通信运行在独立 Node Sidecar 中：
+
+```text
+微信
+  ↕ 腾讯 iLink HTTPS / CDN
+微信 Sidecar
+  ↕ 严格、有界、可验证的进程协议
+Main ChannelDriver
+  ↕
+ChannelService
+  ↕
+GoodBuddy Runtime 与审批
+```
+
+禁止：
+
+- 在 Renderer 中加载微信通信代码。
+- 向 Renderer 暴露 Token、上下文令牌或原始腾讯响应。
+- 把腾讯插件直接加载进 Electron Main。
+- 运行 `openclaw-weixin-cli` 安装器。
+- 仅为微信通道打包完整 OpenClaw。
+
+### 10.2 首期 Sidecar 能力
+
+- 获取和刷新二维码。
+- 轮询扫码状态。
+- 提交一次性验证码。
+- 加载内存中的加密解封凭据。
+- 长轮询文字消息。
+- 发送文字回复。
+- 保持会话 `context_token` 和同步游标。
+- 有界重试、退避、停止和异常退出。
+
+### 10.3 协议扩展
+
+现有 `wechat-sidecar-protocol.ts` 需要拆分为两个方向：
+
+Sidecar 到 Main：
+
+- `status`
+- `qr`
+- `verification_required`
+- `connected`
+- `inbound_text`
+- `reply_result`
+- `fatal_error`
+
+Main 到 Sidecar：
+
+- `start_login`
+- `submit_verification`
+- `start_account`
+- `send_reply`
+- `disconnect`
+- `shutdown`
+
+所有消息使用严格 Zod Schema、版本号、最大长度和关联 ID。协议拒绝未知字段。Token、Cookie、Session 和上下文令牌不得出现在普通状态或消息事件中。
+
+## 11. 凭据与网络安全
+
+### 11.1 凭据
+
+- 微信 bot token 使用 Electron `safeStorage` 加密后保存在 Main 管理的设置文件。
+- 上下文令牌由 Sidecar 运行时持有；如需跨重启保存，必须由 Main 加密持久化。
+- 凭据不得出现在命令行参数、普通环境变量、stdout、Renderer IPC、通知或错误消息中。
+- Sidecar 通过私有继承管道接收本次运行所需凭据。
+- 安全存储不可用时不能完成微信绑定或启用通道。
+
+### 11.2 网络
+
+- 扫码入口固定为已审核的腾讯 HTTPS 主机。
+- 服务端返回的 API 主机和重定向主机必须通过腾讯主机允许列表验证后才能携带 Token 请求。
+- 不允许明文 HTTP 发送微信凭据。
+- 全局“内网兼容模式”不得放宽微信凭据端点的 HTTPS 和主机验证。
+- 日志中的 URL 移除查询字符串，响应体对 Token 和上下文令牌脱敏。
+
+### 11.3 断开与解绑
+
+产品区分：
+
+- 停用：停止收发，保留本地绑定凭据。
+- 断开本地连接：停止收发并清除本地凭据。
+- 微信端解除绑定：只有腾讯提供并验证服务端撤销能力后才可承诺。
+
+当前不得把本地清除描述为“已在微信端彻底解绑”。
+
+## 12. 数据与契约建议
+
+### 12.1 Project
+
+为项目增加可向后兼容的来源字段：
+
+```ts
+type ProjectKind = 'user' | 'channel'
+type ProjectChannel = 'weixin' | 'wecom' | 'dingtalk'
+```
+
+通道项目包含：
+
+- `kind: 'channel'`
+- `channel`
+- 稳定且唯一的通道绑定
+
+现有项目迁移为 `kind: 'user'`。不得通过项目名称推断通道。
+
+### 12.2 Conversation
+
+增加远程会话映射，至少包含：
+
+- `conversationId`
+- `projectId`
+- `channel`
+- `accountId`
+- `externalConversationId`
+- `conversationType`
+- 脱敏显示名
+- 创建和最近消息时间
+
+唯一约束：
+
+```text
+channel + accountId + externalConversationId
+```
+
+### 12.3 Channel Settings
+
+通道公开设置增加：
+
+- `projectId`
+- `defaultWorkMode`
+- `rootPath`
+- `status`
+
+微信私有设置增加加密字段：
+
+- bot token
+- bot/account ID
+- 绑定用户 ID
+- 经验证的 API base URL
+
+Renderer 快照只返回是否已配置和脱敏标识。
+
+### 12.4 任务来源
+
+远程任务保留：
+
+- 通道项目 ID。
+- 远程会话 ID。
+- 通道。
+- 脱敏发送者。
+- 实际工作模式。
+- 请求级确认结果。
+
+不得把 Execute 任务伪装成普通本地任务或只读 delegation。
+
+## 13. IPC 与 Preload
+
+建议增加窄接口：
+
+- 获取通道设置快照。
+- 保存通道项目配置。
+- 开始微信扫码。
+- 刷新微信扫码。
+- 提交微信验证码。
+- 断开微信本地连接。
+- 订阅微信连接状态。
+- 响应远程 Execute 请求级确认。
+- 打开对应通道项目。
+
+所有 IPC：
+
+- 使用共享 Zod Schema 验证。
+- 验证可信 Renderer sender。
+- 不接收 Renderer 提供的项目类型或通道身份作为可信事实。
+- 不返回凭据。
+
+## 14. 关键异常流程
+
+### 14.1 项目重名
+
+存在名为“微信 ClawBot”的普通项目时，仍创建独立通道项目，并通过通道类型而非名称识别。UI 可以显示同名，但必须有“远程通道”分组和微信徽标。
+
+### 14.2 通道项目缺失
+
+如果数据库异常或旧版本操作导致绑定项目缺失，Main 初始化时重新创建并修复设置引用。历史会话无法安全迁移时保留原归属并给出诊断，不静默丢弃。
+
+### 14.3 连接中退出
+
+- 取消二维码轮询。
+- 清除内存验证码。
+- 停止 Sidecar。
+- 不保存未确认凭据。
+
+### 14.4 执行确认期间断线
+
+本机确认仍可拒绝，但不得在通道已断开后启动新的 Execute。已开始的任务按用户明确选择和现有取消策略处理，结果进入本地审计；恢复连接后不得自动重复执行。
+
+### 14.5 重复消息
+
+使用稳定平台消息 ID 去重。平台消息 ID 缺失时，使用账号、会话、发送者、时间和内容摘要构造有界稳定键。确认、任务创建和回复必须共用同一个去重声明。
+
+## 15. 可访问性与响应式
+
+- 通道状态同时使用文字和图标。
+- 模式选择使用语义化单选/分段控件和方向键。
+- 二维码提供状态文字和备用刷新操作，但不把敏感二维码链接作为可复制文本。
+- 验证码错误与输入框建立 `aria-describedby` 关联。
+- Execute 风险确认初始焦点位于“取消”。
+- 关闭对话框后焦点返回触发按钮。
+- 窄窗口下卡片单列，二维码对话框保留 16px 外边距。
+- 浅色、深色和 200% 文字缩放下可完成绑定和确认。
+
+## 16. 验收标准
+
+### 16.1 通道项目
+
+- [ ] 新安装首次启动后存在微信 ClawBot、企业微信和钉钉三个通道项目。
+- [ ] 重启应用不会重复创建通道项目。
+- [ ] 同名普通项目不会被占用或修改。
+- [ ] 通道项目默认根目录为当前用户目录，默认模式为 Ask。
+- [ ] 通道项目在项目选择器的“远程通道”分组中显示。
+- [ ] 停用或断开通道不会删除项目和历史。
+- [ ] 普通项目删除流程不能永久删除通道项目。
+
+### 16.2 设置卡片
+
+- [ ] 设置标签显示为“消息通道”。
+- [ ] 三张卡片均显示项目、根目录、默认模式和连接状态。
+- [ ] 微信卡片可以完成扫码、过期刷新、验证码和连接状态展示。
+- [ ] 切换默认 Execute 前显示目录范围和风险确认。
+- [ ] Renderer 无法读取任何微信 Token 或上下文令牌。
+
+### 16.3 会话
+
+- [ ] 不同通道的消息进入不同通道项目。
+- [ ] 不同发送者或群聊进入独立远程会话。
+- [ ] 重复平台事件不会创建重复会话、消息或任务。
+- [ ] 最近对话、聊天标题和消息均能识别通道与发送者。
+- [ ] 收到普通消息不会强制切换当前页面。
+
+### 16.4 Ask
+
+- [ ] 普通消息默认按卡片配置进入 Ask。
+- [ ] Ask 在 Runtime 边界拒绝所有工具。
+- [ ] 有界结果回传原通道并写入远程会话。
+
+### 16.5 Execute
+
+- [ ] 默认 Execute 或显式执行前缀会创建本机请求级确认。
+- [ ] 未确认、拒绝、超时、退出和停用均不会执行。
+- [ ] 微信消息不能批准自身的 Execute 请求。
+- [ ] 确认后任务使用对应通道项目根目录。
+- [ ] Runtime、沙箱、能力和工具审批规则继续生效。
+- [ ] 任务、活动、工具、成果和最终结果关联到通道项目与远程会话。
+
+### 16.6 生命周期与安全
+
+- [ ] Sidecar 异常退出不会导致 Main 崩溃，并有有界重启限制。
+- [ ] 应用退出会取消长轮询并停止 Sidecar。
+- [ ] 微信凭据使用系统安全存储加密。
+- [ ] 任何普通日志、IPC、错误和通知中不存在凭据。
+- [ ] Token 只发送到已审核的腾讯 HTTPS 主机。
+
+## 17. 实施阶段
+
+### 阶段一：通道项目基础
+
+- Project 数据迁移与通道类型。
+- 三个通道项目幂等创建。
+- 项目选择器“远程通道”分组。
+- 三张设置卡片接入项目、目录和模式配置。
+- 企业微信、钉钉消息建立独立远程会话。
+
+### 阶段二：微信文字通道
+
+- 微信 iLink Sidecar。
+- 扫码、验证码、加密凭据和生命周期。
+- 微信文字收发与稳定去重。
+- 微信远程会话。
+- Ask 模式。
+
+### 阶段三：受控 Execute
+
+- 本机请求级确认。
+- Execute Runtime 接入。
+- 工具审批和活动关联。
+- 结果回传、取消、超时和失败恢复。
+
+### 阶段四：后续扩展
+
+- 有界图片、语音、文件和视频。
+- 多微信账号。
+- 更细的项目路由。
+- 已验证的微信端解除绑定。
+
+## 18. 测试要求
+
+至少覆盖：
+
+- 数据迁移和通道项目幂等创建。
+- 同名普通项目隔离。
+- 设置 Schema 与 Renderer 脱敏快照。
+- QR 状态机、过期、验证码和非法转换。
+- Sidecar 双向协议未知字段、超长字段和凭据泄漏拒绝。
+- 腾讯主机允许列表和重定向校验。
+- 消息去重、会话映射、并发和取消。
+- Ask 工具拒绝。
+- Execute 请求级确认通过、拒绝、超时、退出和断线。
+- 工具审批不被远程来源绕过。
+- 发件箱投递失败不重复执行。
+- 项目选择器、设置卡片、扫码对话框和确认对话框的键盘与无障碍行为。
+- Windows、macOS、Linux 的默认用户目录和 Sidecar 关闭行为。
+
+实现完成后运行：
+
+```text
+npm test
+npm run typecheck
+npm run lint
+npm run build
+```
+
+## 19. 发布条件
+
+满足以下条件后才可默认向用户提供微信 Execute：
+
+1. 微信文字 Ask 全流程稳定。
+2. 请求级确认不能从远程通道绕过。
+3. 凭据不会进入 Renderer、日志或普通子进程参数。
+4. Sidecar 网络目标和重定向已实施严格允许列表。
+5. 通道项目和远程会话的来源标识在所有入口持续可见。
+6. 任务重复投递不会导致重复执行。
+7. 应用退出、断线和更新过程中不会留下失控执行。
+8. 腾讯 iLink 独立宿主使用范围和本地断开语义已完成发布前确认。
