-# 2-of-3 服务器参与选项 - 纯新增实施方案
-
-## 目标
-允许 2-of-3 MPC 用户勾选"包含服务器备份"参与签名，以便在丢失一个设备时转出资产。
-
-## 核心设计
-
-### 安全限制
- **仅** 2-of-3 配置显示此选项
- 其他配置（3-of-5, 4-of-7等）不显示
-
-### 实施范围
- ✅ 只修改 Android 客户端
- ❌ **不需要**修改后端（account-service, message-router）
- ✅ 纯新增代码，现有逻辑保持不变
-
-## 修改文件清单
-
-### 1. TssRepository.kt（2处新增）
-
-#### 1.1 新增辅助方法（private）
-```kotlin
-// 位置：3712行之前（类内部末尾）
-/**
- * 构建参与方列表（新增辅助方法）
- * @param participants 所有参与方
- * @param includeServerParties 是否包含服务器方（默认 false，保持现有行为）
- */
-private fun buildSigningParticipantList(

-    includeServerParties: Boolean = false
-): List<Pair<String, Int>> {

-        // 包含所有参与方（含服务器）
-        participants
-    } else {
-        // 过滤掉服务器方（现有行为）
-        participants.filter { !it.partyId.startsWith("co-managed-party-") }
-    }
-    return filtered.map { Pair(it.partyId, it.partyIndex) }
-}
-```
-
-#### 1.2 新增签名会话创建方法
-```kotlin
-// 位置：buildSigningParticipantList 之后
-/**
- * 创建签名会话（支持选择是否包含服务器）
- * @param includeServerBackup 是否包含服务器备份参与方（仅 2-of-3 时使用）
- * 新增方法，不影响现有 createSignSession

-```kotlin

-
-### 3. TransferScreen.kt（UI 新增）
-
-```kotlin
-// 在交易确认界面新增复选框（Step 2）
-// 位置：密码输入框之后
-
-// 仅在 2-of-3 时显示
-if (wallet.thresholdT == 2 && wallet.thresholdN == 3) {

-    var includeServerBackup by remember { mutableStateOf(false) }
-
-    Row(
-        modifier = Modifier
-            .fillMaxWidth()
-            .padding(horizontal = 16.dp),
-        verticalAlignment = Alignment.CenterVertically
-    ) {
-        Checkbox(
-            checked = includeServerBackup,
-            onCheckedChange = { includeServerBackup = it }
-        )
-        Spacer(modifier = Modifier.width(8.dp))
-        Column {
-            Text(
-                text = "包含服务器备份参与签名",
-                style = MaterialTheme.typography.bodyMedium
-            )
-            Text(

-            )
-        }
-    }
-}
-```
-
-### 4. MainActivity.kt（传递参数）
-
-```kotlin
-// 修改 TransferScreen 的 onConfirmTransaction 回调
-onConfirmTransaction = { includeServer ->
-    viewModel.initiateSignSessionWithOptions(
-        shareId = shareId,
-        password = "",
-        includeServerBackup = includeServer
-    )
-}
-```
-
-## 测试场景
-
-### 场景1：2-of-3 正常使用（不勾选）
- 设备A + 设备B 签名 ✅
- 服务器被过滤（现有行为）
-
-### 场景2：2-of-3 设备丢失（勾选）
- 设备A + 服务器 签名 ✅
- 用户明确勾选"包含服务器备份"
-
-### 场景3：3-of-5 配置
- 不显示复选框 ✅
- 保持现有行为
-
-## 优势
-
-1. ✅ **零后端修改**：后端只接收 parties 数组
-2. ✅ **完全向后兼容**：默认行为不变
-3. ✅ **安全限制**：仅 2-of-3 可用
-4. ✅ **纯新增**：不修改现有方法
-5. ✅ **用户明确选择**：需要主动勾选
-
-## 实施顺序
-
-1. TssRepository：新增辅助方法
-2. TssRepository：新增 createSignSessionWithOptions
-3. MainViewModel：新增 initiateSignSessionWithOptions
-4. TransferScreen：新增 UI 复选框
-5. MainActivity：传递参数
-6. 测试编译和功能
