+W1,合同建档与现状确认,固定本轮目标为企业微信个人应用消息推送并确认当前公网仍只有 mock 通知渠道；本 Issue 不改业务数据。,1) 新合同 CSV 校验通过；2) 当前 mock 渠道与 R5 阻断原因记录清晰；3) 明确不使用群机器人作为正式审批通知口径。,流程级验证：git status --short；只读查询公网通知渠道摘要；python3 /home/shunli/.codex/skills/plan/scripts/validate_issues_csv.py issues/2026-05-11_08-56-44-wecom-personal-app-message-r5-closeout.csv。,git|python3|node|manual,DONE,DONE,DONE,issues/2026-05-11_08-56-44-wecom-personal-app-message-r5-closeout.csv,[],回滚路径：删除本 CSV；不涉及代码或远端数据。已确认 W1 合同存在，公网当前仍以 mock 渠道阻断真实企微个人消息验收。
+W2,后端企业微信个人应用消息适配器,新增 wecom_app_message 通知渠道模式，复用现有 WECOM_* 应用配置向绑定成员发送企业微信应用消息。,1) 渠道模式支持 wecom_app_message；2) textcard 带 deeplink，缺 deeplink 时降级 text；3) 仅向已绑定且启用通知的收件人发送；4) 无绑定不阻断业务并记录 wecom_app_no_bound_recipients；5) delivery 不记录 secret/token。,流程级验证：cd server && npm run prisma:validate；cd server && node --check src/services/integrations/im/wecom.js；cd server && node --check src/services/notificationDispatcher.js；cd server && npm test -- tests/unit/routes/notifications.test.js tests/unit/services/notificationDispatcher.test.js tests/unit/services/integrations/dispatcher.test.js tests/unit/routes/wecomAuth.test.js。,node|npm,DONE,DONE,DONE,server/src/services/integrations/im/wecom.js|server/src/services/notificationDispatcher.js|server/src/routes/notifications.js,"[""W1""]",不新增 Prisma migration；如企业微信 API 权限错误，记录错误码并停止 R5 完成。已通过 Prisma validate、node --check 和 4 组通知/企微单测。
+W3,管理端通知渠道支持个人应用消息,通知渠道管理页新增企微应用消息个人模式，隐藏 webhook 必填和 secret 要求，保留路由与模板配置。,1) 管理页模式可选 wecom_app_message；2) 该模式不要求 Webhook URL/Secret；3) Mock 和 webhook 旧配置不回归；4) typecheck/build 通过。,流程级验证：cd client && npm run typecheck；cd client && npm run build；人工或 Playwright 打开 /system/notification-channels 确认模式选项和字段可理解。,npm|playwright,DONE,DONE,DONE,client/src/pages/NotificationChannelsPage.tsx|client/src/api/notificationChannels.ts,"[""W2""]",仅管理端配置 UI；不改变普通用户页面。已通过前端 typecheck 与生产 build。
