+# A-route open_conversation 窗口验证说明
+
+日期：2026-07-11
+分支：`codex/a-route-rpa-send`
+
+## 本轮目标
+
+用户明确当前先不要求真实发送消息，只要求“打开那个会话窗口”，用来验证数字员工是否能：
+
+1. 识别会话窗口。
+2. 定位发送编辑框。
+3. 定位发送按钮/文件按钮。
+4. 执行一次可审计的点击。
+
+本地环境没有 iSphere 服务端，无法登录，所以真实会话窗口不能通过正常业务路径打开。
+
+## 已实现：离线会话窗口探针
+
+新增脚本：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File E:\coding\codex\isphere-ai-bridge\scripts\open-offline-chat-window-probe.ps1 -ProbeClick
+```
+
+它会打开一个本地 WinForms 会话窗口探针，不连接服务端，不发送真实消息。关键 UIA 标识对齐真实会话窗口/既有 RPA 选择器：
+
+| 目标 | AutomationId / Name |
+| --- | --- |
+| 会话窗口 | `frmP2PChat` |
+| 联系人搜索框 | `skinAlphaTxt` |
+| 消息展示区 | `rtbRecvMessage` |
+| 发送编辑框 | `rtbSendMessage` |
+| 发送按钮 | `btnSend` |
+| 文件按钮 | `btnSendFile` |
+| 离线提示 | `offlineSendBlocker` |
+
+当传入 `-ProbeClick` 时，脚本会调用当前分支已有的 WinHelper UIA 动作，把文本写入 `rtbSendMessage` 并点击 `btnSend`。按钮点击只写本地 marker 文件，字段固定为：
+
+- `sent_real_message=false`
+- `uploaded_real_file=false`
+
+因此这个动作只验证 UIA 识别、定位、写入、点击链路，不触发真实消息发送。
+
+## 自动化测试
+
+新增测试：
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File E:\coding\codex\isphere-ai-bridge\scripts\test-open-offline-chat-window-probe.ps1
+```
+
+测试断言：
+
+- 根窗口 `root_automation_id=frmP2PChat`
+- 找到 `rtbSendMessage`
+- 找到 `btnSend`
+- 找到 `btnSendFile`
+- `ProbeClick` 后写入 marker
+- marker 文本与 UIA 写入文本一致
+- `sent_real_message=false`
+- `uploaded_real_file=false`
+
+## 真实 `frmP2PChat` 破解进度
+
+已继续尝试直接构造真实类型：
+
+```text
+IMPP.Client.Business.ChatManager.SingleChat.frmP2PChat
+```
+
+构造函数签名：
+
+```text
+frmP2PChat(com.vision.smack.Chat chat, string pluginInfo, string extendTabJson)
+```
+
+已补过的离线依赖包括：
+
+- `IMPPManager.Instance.MessageCenter`
+- `IMPPManager.Instance.LogonUser`
+- `IMPPManager.Instance.UserInfo`
+- `SmarkManager.Connection`
+- `SmarkManager.RosterManager`
+- `SmarkManager.PresenceManager`
+- `SmarkManager.P2PChatManager`
+- `ConfigSystemManager.config`
+- `P2PChat.OtherJid`
+
+仍未成功打开真实窗体。当前阻塞不再是脚本能力，而是构造函数内部把窗体初始化、登录态、连接态、名册状态、消息中心事件、配置状态混在一起。IL 证据显示构造函数中直接访问：
+
+- `IMPPManager.Instance.Connection.add_OnConnectError`
+- `IMPPManager.Instance.Connection.add_OnReConnectOk`
+- `P2PChat.OtherJid.getBareJid`
+- `IMPPManager.Instance.UserInfo.get_Jid`
+- `UCChatSendMessageBox.GetChatRichTextBox`
+- `UCChatSendMessageBox.GetReceiptCheckBox`
+- `IMPPManager.Instance.GetMessageCenter().add_OnTcpMessageArrived`
+- `IMPPManager.Instance.RosterManager.UpdateStrangerStatus`
+- `Config.BaseConfig.VisualPhoneEnable`
+
+这说明真实 `frmP2PChat` 不是独立窗口类；它要求完整登录运行态。没有服务端/登录态时继续硬构造，投入会越来越像“重建一个假客户端运行时”。
+
+## 当前业务结论
+
+从“验证 RPA 能否识别、定位、点击会话窗口”的业务目标看，本轮已经可验证：
+
+- 会话窗口可打开。
+- 核心 AutomationId 可识别。
+- 文本可写入。
+- 按钮可点击。
+- 点击结果可留本地审计 marker。
+- 全程不发真实消息、不上传真实文件。
+
+从“真实 iSphere 会话窗口”的目标看，仍需要在线登录环境或继续补完整客户端运行态。
+
+## 下一步建议
+
+1. 当前分支先使用 `open-offline-chat-window-probe.ps1` 验证 RPA 识别/定位/点击效果。
+2. 在线环境拿到真实登录后的 `frmP2PChat` HWND 后，用同一套 WinHelper 选择器直接验证真实窗口。
+3. 如果必须离线打开真实窗体，再继续走“补完整 IMPPManager/SmarkManager/Config/BaseConfig/MessageCenter 运行态”的破解路线。

+## Task 6: Open conversation window probe for A-route RPA
+
+**Files:**
+- Create: `scripts/open-offline-chat-window-probe.ps1`
+- Create: `scripts/test-open-offline-chat-window-probe.ps1`
+- Create: `docs/source-discovery/2026-07-11-a-route-open-conversation-window.md`
+
+**Purpose:** local environment cannot log in, but RPA still needs a stable
+conversation-window surface to prove identify/locate/click behavior. This task
+adds a no-network WinForms probe using the real selector names
+`frmP2PChat`, `rtbRecvMessage`, `rtbSendMessage`, `btnSend`, and
+`btnSendFile`.
+
+- [x] Write failing test proving the open-conversation probe script is required.
+- [x] Implement the offline chat-window probe.
+- [x] Verify UIA classification finds send editor, send button, and file button.
+- [x] Verify `-ProbeClick` writes text and clicks `btnSend`.
+- [x] Verify marker says `sent_real_message=false` and `uploaded_real_file=false`.
+- [x] Document why direct offline construction of the real `frmP2PChat` is still blocked by login/runtime singletons.
