# Boss 微信式消息转发 Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 把当前原生 Android 的“备注转发页”重构成微信式消息转发链，支持单条消息转发、多选消息合并转发、统一目标会话选择页，以及服务端 `forwardSource / forwardBundle / approvalRequired` 账本结构。

**Architecture:** 保留现有 `BossState -> Next API -> BossApiClient -> 原生活动页` 主链，不引入新基础设施。服务端把 `POST /api/v1/projects/[projectId]/forwards` 从“备注转发”升级成结构化转发接口；原生端在 `ProjectDetailActivity` 内补消息操作菜单、多选状态和目标会话选择页，并以 `ForwardTargetActivity` 承接统一转发目标选择。

**Tech Stack:** Next.js App Router, TypeScript, file-backed `data/boss-state.json`, 原生 Android AppCompat + XML, HttpURLConnection, JUnit4

### Task 1: 升级服务端转发账本和接口结构

**Files:**
- Modify: `src/lib/boss-data.ts`
- Modify: `src/app/api/v1/projects/[projectId]/forwards/route.ts`
- Modify: `src/lib/boss-projections.ts`
- Test: `npm run build`

- [ ] **Step 1: 先把新的消息结构写进 failing contract 注释和类型定义**

在 `src/lib/boss-data.ts` 的 `MessageKind` 与 `Message` 附近先写出新结构，让后续编译先报缺字段：

```ts
export type MessageKind =
  | "text"
  | "voice_intent"
  | "image_intent"
  | "video_intent"
  | "forward_notice"
  | "forward_single"
  | "forward_bundle";

export interface ForwardSource {
  sourceProjectId: string;
  sourceProjectName: string;
  sourceThreadId?: string;
  sourceThreadTitle?: string;
  sourceMessageId: string;
  forwardedBy: string;
  forwardedAt: string;
}

export interface ForwardBundleItem {
  messageId: string;
  senderLabel: string;
  body: string;
  kind: string;
  sentAt: string;
}

export interface ForwardBundlePayload {
  sourceProjectId: string;
  sourceProjectName: string;
  sourceThreadId?: string;
  sourceThreadTitle?: string;
  itemCount: number;
  startedAt: string;
  endedAt: string;
  items: ForwardBundleItem[];
}

export interface Message {
  id: string;
  sender: MessageSender;
  senderLabel: string;
  body: string;
  sentAt: string;
  kind?: MessageKind;
  forwardSource?: ForwardSource;
  forwardBundle?: ForwardBundlePayload;
}
```

- [ ] **Step 2: 运行构建，确认当前实现还不支持这些结构**

Run:

```bash
cd /Users/kris/code/boss
npm run build
```

Expected: 先因为 `forwardProjectMessage` 和相关消息使用点不完整而失败，或者至少需要补 route / render 类型。

- [ ] **Step 3: 用最小实现升级 `forwardProjectMessage` 输入结构**

把 `src/lib/boss-data.ts` 的旧签名：

```ts
export async function forwardProjectMessage(payload: {
  sourceProjectId: string;
  targetProjectId: string;
  note: string;
})
```

改成：

```ts
export async function forwardProjectMessage(payload:
  | {
      sourceProjectId: string;
      mode: "single";
      targetProjectId: string;
      sourceMessageId: string;
      requestedBy: string;
    }
  | {
      sourceProjectId: string;
      mode: "bundle";
      targetProjectId: string;
      sourceMessageIds: string[];
      requestedBy: string;
    }
) {}
```

并补 3 个最小 helper：

```ts
function findProjectMessage(project: Project, messageId: string) {}
function buildForwardSingleMessage(input: { source: Project; target: Project; message: Message; requestedBy: string }) {}
function buildForwardBundleMessage(input: { source: Project; target: Project; messages: Message[]; requestedBy: string }) {}
```

最小行为要求：

- `single` 生成 `kind: "forward_single"`，并带 `forwardSource`
- `bundle` 生成 `kind: "forward_bundle"`，并带 `forwardBundle`
- `target.preview` 更新为新消息正文或卡片摘要
- `source` 侧继续写一条“已转发到《目标会话》”的轻量日志

- [ ] **Step 4: 在 `forwardProjectMessage` 里补审批闸口最小返回**

在 `src/lib/boss-data.ts` 内先加最小判定：

```ts
function requiresForwardApproval(source: Project, target: Project) {
  return source.collaborationMode === "approval_required" && target.id !== "master-agent";
}
```

并让 `forwardProjectMessage` 在命中审批时返回：

```ts
return {
  approvalRequired: true,
  approvalReason: "NON_DEVELOPMENT_THREAD_FORWARD",
};
```

要求：

- 审批场景下不写入目标消息账本
- 正常场景才写入目标消息账本并返回 `message`

- [ ] **Step 5: 升级 route 输入校验**

在 `src/app/api/v1/projects/[projectId]/forwards/route.ts` 里把旧输入：

```ts
{
  targetProjectId?: string;
  note?: string;
}
```

替换成：

```ts
type ForwardBody =
  | {
      mode?: "single";
      targetProjectId?: string;
      sourceMessageId?: string;
    }
  | {
      mode?: "bundle";
      targetProjectId?: string;
      sourceMessageIds?: string[];
    };
```

route 最小逻辑：

- `mode=single` 时要求 `sourceMessageId`
- `mode=bundle` 时要求 `sourceMessageIds.length > 1`
- 调用 `forwardProjectMessage({ ..., requestedBy: session.account })`
- 返回：

```ts
return NextResponse.json({
  ok: true,
  message: result.message ?? null,
  approvalRequired: Boolean(result.approvalRequired),
  approvalReason: result.approvalReason ?? null,
});
```

- [ ] **Step 6: 重新构建，确认类型闭合**

Run:

```bash
cd /Users/kris/code/boss
npm run build
```

Expected: `Compiled successfully`

- [ ] **Step 7: Commit**

```bash
git add src/lib/boss-data.ts src/app/api/v1/projects/[projectId]/forwards/route.ts src/lib/boss-projections.ts
git commit -m "feat: add structured message forwarding payloads"
```

### Task 2: 先用单测拉出原生多选转发状态机

**Files:**
- Modify: `android/app/src/main/java/com/hyzq/boss/ProjectChatUiState.java`
- Modify: `android/app/src/test/java/com/hyzq/boss/ProjectChatUiStateTest.java`

- [ ] **Step 1: 先写 failing test，覆盖多选模式切换**

在 `android/app/src/test/java/com/hyzq/boss/ProjectChatUiStateTest.java` 先补这些测试：

```java
@Test
public void entersMultiSelectModeAfterFirstToggle() {
    ProjectChatUiState.SelectionState state = ProjectChatUiState.toggleSelection(null, "m1");
    assertTrue(state.multiSelecting);
    assertEquals(1, state.selectedMessageIds.size());
    assertTrue(state.selectedMessageIds.contains("m1"));
}

@Test
public void deselectingLastMessageExitsMultiSelectMode() {
    ProjectChatUiState.SelectionState state = new ProjectChatUiState.SelectionState(true, java.util.Set.of("m1"));
    ProjectChatUiState.SelectionState next = ProjectChatUiState.toggleSelection(state, "m1");
    assertFalse(next.multiSelecting);
    assertTrue(next.selectedMessageIds.isEmpty());
}

@Test
public void bundleForwardRequiresAtLeastTwoMessages() {
    ProjectChatUiState.SelectionState state = new ProjectChatUiState.SelectionState(true, java.util.Set.of("m1"));
    assertFalse(ProjectChatUiState.canForwardSelection(state));
}
```

- [ ] **Step 2: 跑单测确认先红**

Run:

```bash
cd /Users/kris/code/boss/android
./gradlew testDebugUnitTest --tests com.hyzq.boss.ProjectChatUiStateTest --no-daemon
```

Expected: FAIL，提示 `SelectionState` / `toggleSelection` / `canForwardSelection` 尚未实现。

- [ ] **Step 3: 在 `ProjectChatUiState.java` 写最小实现**

补最小状态对象与 helper：

```java
public static final class SelectionState {
    public final boolean multiSelecting;
    public final java.util.Set<String> selectedMessageIds;

    public SelectionState(boolean multiSelecting, java.util.Set<String> selectedMessageIds) {
        this.multiSelecting = multiSelecting;
        this.selectedMessageIds = selectedMessageIds;
    }
}

public static SelectionState emptySelection() {
    return new SelectionState(false, new java.util.LinkedHashSet<>());
}

public static SelectionState toggleSelection(@Nullable SelectionState current, String messageId) {}

public static boolean canForwardSelection(@Nullable SelectionState state) {
    return state != null && state.selectedMessageIds.size() >= 2;
}
```

要求：

- 第一次 toggle 进入多选
- 取消最后一条选中后退出多选
- 保持插入顺序，后面 bundle 卡片会用到

- [ ] **Step 4: 跑单测确认转绿**

Run:

```bash
cd /Users/kris/code/boss/android
./gradlew testDebugUnitTest --tests com.hyzq.boss.ProjectChatUiStateTest --no-daemon
```

Expected: PASS

- [ ] **Step 5: Commit**

```bash
git add android/app/src/main/java/com/hyzq/boss/ProjectChatUiState.java android/app/src/test/java/com/hyzq/boss/ProjectChatUiStateTest.java
git commit -m "feat: add native chat forward selection state"
```

---

### Task 3: 先做会话选择页与 API payload builder，再接聊天页入口

**Files:**
- Modify: `android/app/src/main/java/com/hyzq/boss/BossApiClient.java`
- Create: `android/app/src/main/java/com/hyzq/boss/ForwardTargetActivity.java`
- Create: `android/app/src/test/java/com/hyzq/boss/ForwardTargetActivityTest.java`
- Modify: `android/app/src/main/java/com/hyzq/boss/ProjectForwardActivity.java`
- Modify: `android/app/src/main/AndroidManifest.xml`
- Create: `android/app/src/main/res/layout/activity_forward_target.xml`

- [ ] **Step 1: 先写 failing test，覆盖目标会话过滤和单选规则**

在 `android/app/src/test/java/com/hyzq/boss/ForwardTargetActivityTest.java` 先写：

```java
@Test
public void filtersOutSourceConversationFromTargets() {
    JSONArray conversations = new JSONArray()
            .put(new StubJSONObject().withString("projectId", "source").withString("projectTitle", "源会话"))
            .put(new StubJSONObject().withString("projectId", "target").withString("projectTitle", "目标会话"));

    java.util.List<JSONObject> result = ForwardTargetActivity.collectSelectableTargets(conversations, "source");

    assertEquals(1, result.size());
    assertEquals("target", result.get(0).optString("projectId"));
}

@Test
public void singleModeRequiresOneMessageId() throws Exception {
    JSONObject payload = ForwardTargetActivity.buildForwardPayload("single", "m1", java.util.List.of());
    assertEquals("single", payload.optString("mode"));
    assertEquals("m1", payload.optString("sourceMessageId"));
}

@Test
public void bundleModeUsesOrderedMessageIds() throws Exception {
    JSONObject payload = ForwardTargetActivity.buildForwardPayload("bundle", null, java.util.List.of("m1", "m2"));
    assertEquals("bundle", payload.optString("mode"));
    assertEquals(2, payload.optJSONArray("sourceMessageIds").length());
}
```

- [ ] **Step 2: 跑单测确认先红**

Run:

```bash
cd /Users/kris/code/boss/android
./gradlew testDebugUnitTest --tests com.hyzq.boss.ForwardTargetActivityTest --no-daemon
```

Expected: FAIL，提示 `ForwardTargetActivity` helper 未实现。

- [ ] **Step 3: 在 `BossApiClient.java` 补结构化转发方法**

把旧方法：

```java
public ApiResponse forwardProjectMessage(String projectId, String targetProjectId, String note)
```

替换为：

```java
public ApiResponse forwardProjectMessage(String projectId, String targetProjectId, JSONObject payload)
```

方法内最小逻辑：

```java
JSONObject requestPayload = payload == null ? new JSONObject() : payload;
requestPayload.put("targetProjectId", targetProjectId);
return requestWithRestore("POST", "/api/v1/projects/" + encode(projectId) + "/forwards", requestPayload);
```

- [ ] **Step 4: 写 `ForwardTargetActivity` 最小实现**

活动页至少需要：

```java
public static final String EXTRA_SOURCE_PROJECT_ID = "source_project_id";
public static final String EXTRA_FORWARD_MODE = "forward_mode";
public static final String EXTRA_SOURCE_MESSAGE_ID = "source_message_id";
public static final String EXTRA_SOURCE_MESSAGE_IDS = "source_message_ids";

static java.util.List<JSONObject> collectSelectableTargets(JSONArray conversations, String sourceProjectId) {}
static JSONObject buildForwardPayload(String mode, @Nullable String sourceMessageId, java.util.List<String> sourceMessageIds) throws JSONException {}
```

页面行为最小版：

- 拉取 `apiClient.getConversations()`
- 过滤源会话
- 列出微信式会话 cell
- 点中某个目标会话后调用新的 `forwardProjectMessage`
- `approvalRequired=true` 时先提示“已提交主 Agent 审批”
- 正常成功时 `setResult(RESULT_OK)` 后 finish

- [ ] **Step 5: 让旧 `ProjectForwardActivity` 只做兼容跳转**

在 `android/app/src/main/java/com/hyzq/boss/ProjectForwardActivity.java` 中删除旧备注输入主链，保留：

```java
Intent intent = new Intent(this, ForwardTargetActivity.class);
intent.putExtra(ForwardTargetActivity.EXTRA_SOURCE_PROJECT_ID, projectId);
intent.putExtra(ForwardTargetActivity.EXTRA_FORWARD_MODE, "single_legacy");
startActivity(intent);
finish();
```

并把标题副文案改成“正在切换到微信式转发”。

- [ ] **Step 6: 跑单测确认转绿**

Run:

```bash
cd /Users/kris/code/boss/android
./gradlew testDebugUnitTest --tests com.hyzq.boss.ForwardTargetActivityTest --no-daemon
```

Expected: PASS

- [ ] **Step 7: Commit**

```bash
git add android/app/src/main/java/com/hyzq/boss/BossApiClient.java android/app/src/main/java/com/hyzq/boss/ForwardTargetActivity.java android/app/src/main/java/com/hyzq/boss/ProjectForwardActivity.java android/app/src/main/AndroidManifest.xml android/app/src/main/res/layout/activity_forward_target.xml android/app/src/test/java/com/hyzq/boss/ForwardTargetActivityTest.java
git commit -m "feat: add native forward target picker"
```

---

### Task 4: 把消息长按、多选和转发结果真正接进聊天页

**Files:**
- Modify: `android/app/src/main/java/com/hyzq/boss/ProjectDetailActivity.java`
- Modify: `android/app/src/main/java/com/hyzq/boss/BossUi.java`
- Modify: `android/app/src/main/res/layout/activity_project_chat.xml`
- Modify: `android/app/src/main/java/com/hyzq/boss/ProjectChatUiState.java`
- Modify: `android/app/src/test/java/com/hyzq/boss/ProjectChatUiStateTest.java`

- [ ] **Step 1: 先写 failing test，覆盖 forward kind 的 UI 标签**

先在 `android/app/src/test/java/com/hyzq/boss/ProjectChatUiStateTest.java` 追加：

```java
@Test
public void singleForwardMessageUsesSingleModeLabel() {
    assertEquals("转发", ProjectChatUiState.labelForForwardKind("forward_single"));
}

@Test
public void bundleForwardMessageUsesBundleModeLabel() {
    assertEquals("聊天记录", ProjectChatUiState.labelForForwardKind("forward_bundle"));
}
```

- [ ] **Step 2: 跑单测确认先红**

Run:

```bash
cd /Users/kris/code/boss/android
./gradlew testDebugUnitTest --tests com.hyzq.boss.ProjectChatUiStateTest --no-daemon
```

Expected: FAIL，提示 `labelForForwardKind` 未定义。

- [ ] **Step 3: 在 `BossUi.java` 增加转发消息和聊天记录卡片**

新增两个 builder：

```java
public static LinearLayout buildForwardSingleBubble(
        Context context,
        String senderLabel,
        String body,
        @Nullable String meta,
        @Nullable String sourceLabel,
        boolean outgoing
) {}

public static LinearLayout buildForwardBundleCard(
        Context context,
        String senderLabel,
        String cardTitle,
        String summary,
        @Nullable String meta,
        boolean outgoing
) {}
```

要求：

- `forward_single` 仍看起来像普通消息 bubble
- `forward_bundle` 明显是聊天记录卡片，但不能长成控制台卡片

- [ ] **Step 4: 在 `ProjectDetailActivity.java` 接入长按与多选**

最小实现顺序：

1. 为每条消息 view 绑定 `messageId`
2. 长按消息时弹出原生 `AlertDialog` 操作菜单：`转发 / 多选 / 复制 / 删除 / 取消`
3. `转发` 时直接打开 `ForwardTargetActivity`
4. `多选` 时切换 `SelectionState`
5. 多选模式下顶部切为 `取消 + 已选数量`
6. 底部输入区切换为单按钮 `转发`

关键入口：

```java
private void openSingleForwardTarget(String sourceMessageId) {}
private void openBundleForwardTarget(java.util.List<String> sourceMessageIds) {}
private void enterMultiSelectFromMessage(String messageId) {}
private void exitMultiSelect() {}
```

- [ ] **Step 5: 在消息渲染分支中接入新 kind**

把现有 `labelForMessageKind(...)` 和消息渲染分支补成：

```java
case "forward_single":
    return BossUi.buildForwardSingleBubble(...);
case "forward_bundle":
    return BossUi.buildForwardBundleCard(...);
```

并让 `ProjectChatUiState.labelForForwardKind(...)` 提供：

```java
"forward_single" -> "转发"
"forward_bundle" -> "聊天记录"
```

- [ ] **Step 6: 跑 Android 编译和单测**

Run:

```bash
cd /Users/kris/code/boss/android
./gradlew testDebugUnitTest :app:compileDebugJavaWithJavac assembleDebug --no-daemon
```

Expected: `BUILD SUCCESSFUL`

- [ ] **Step 7: 跑 Web 构建与接口烟测**

Run:

```bash
cd /Users/kris/code/boss
npm run lint
npm run build
npm start
curl -sS http://127.0.0.1:3000/api/health
curl -sS -H 'Content-Type: application/json' -d '{"mode":"single","targetProjectId":"master-agent","sourceMessageId":"m-test"}' http://127.0.0.1:3000/api/v1/projects/boss-console-ui/forwards
```

Expected:

- `lint` 通过
- `build` 通过
- `/api/health` 返回 `{ ok: true }`
- `/forwards` 返回结构化 JSON，包含 `message` 或 `approvalRequired`

- [ ] **Step 8: Commit**

```bash
git add android/app/src/main/java/com/hyzq/boss/ProjectDetailActivity.java android/app/src/main/java/com/hyzq/boss/BossUi.java android/app/src/main/res/layout/activity_project_chat.xml android/app/src/main/java/com/hyzq/boss/ProjectChatUiState.java android/app/src/test/java/com/hyzq/boss/ProjectChatUiStateTest.java
git commit -m "feat: add wechat style native message forwarding"
```

### Task 5: 文档、发布和完整验证

**Files:**
- Modify: `README.md`
- Modify: `docs/architecture/current_runtime_and_deploy_status_cn.md`
- Modify: `docs/architecture/api_and_service_inventory_cn.md`

- [ ] **Step 1: 同步文档**

把以下事实写回文档：

- 原生 Android 已支持单条消息转发
- 原生 Android 已支持多选合并转发
- 新增 `ForwardTargetActivity`
- `POST /api/v1/projects/[projectId]/forwards` 已支持 `single / bundle`
- 单条消息落 `forwardSource`
- 多条消息落 `forwardBundle`
- 审批闸口已预留

- [ ] **Step 2: 完整验证**

Run:

```bash
cd /Users/kris/code/boss
npm run lint
npm run build
curl -sS http://127.0.0.1:3000/api/health
curl -sS http://127.0.0.1:4317/health
cd android && ./gradlew testDebugUnitTest :app:compileDebugJavaWithJavac assembleDebug --no-daemon
cd /Users/kris/code/boss
JAVA_HOME=$(/usr/libexec/java_home) npm run apk:release
JAVA_HOME=$(/usr/libexec/java_home) npm run aab:release
./scripts/deploy-server.sh
"$HOME/.codex/skills/boss-server-debug/scripts/server_ssh.sh" exec "curl -sS http://127.0.0.1:3000/api/health"
curl -sS https://boss.hyzq.net/api/health
```

Expected:

- 全部成功
- 公网元数据刷新到新版本

- [ ] **Step 3: Commit**

```bash
git add README.md docs/architecture/current_runtime_and_deploy_status_cn.md docs/architecture/api_and_service_inventory_cn.md
git commit -m "docs: update forwarding architecture and runtime status"
```
