+# 🎯 Spec Kit 重新开始 - 完整开发工作流
+
+## 📋 项目重置状态
+
+**✅ 已完成:**
+- main分支清理完毕 (87个TypeScript文件)
+- 中文宪章v1.2.0生效，库优先架构原则
+- 一致性检查工具完备
+- 现有feature已备份至 `backup/features/20250928/`
+- 清理现有feature分支，准备全新开始
+
+---
+
+## 🎯 新Feature开发工作流 (基于中文宪章)
+
+### Phase 1: 项目架构规划 📐
+
+#### 1.1 核心库识别和规划
+**遵循宪章原则一: 库优先架构**
+
+```bash
+# 第一步: 识别核心业务库
+libs/
+├── core-trading/          # 核心交易逻辑库
+├── multi-exchange/        # 多交易所适配器库
+├── credential-manager/    # 凭证管理库
+├── risk-control/          # 风险控制库
+├── market-data/           # 市场数据库
+└── http-client/           # HTTP客户端库
+```
+
+#### 1.2 项目级别依赖架构
+
+```
+应用层 (src/)
+    ↓
+业务库层 (libs/)
+    ↓
+基础设施层 (packages/)
+    ↓
+外部依赖 (node_modules/)
+```
+
+### Phase 2: Feature开发标准流程 🔄
+
+#### 2.1 Feature启动 (`/specify`)
+
+```bash
+# 创建新feature规格
+/specify "实现可扩展的多平台HTTP客户端，支持Pacifica和未来交易所集成"
+```
+
+#### 2.2 规划确认 (`/plan`)
+
+```bash
+# 生成实施计划
+/plan
+```
+
+#### 2.3 任务生成 (`/tasks`)
+
+```bash
+# 生成开发任务列表
+/tasks
+```
+
+#### 2.4 质量分析 (`/analyze`)
+
+```bash
+# 检查一致性和质量
+/analyze
+```
+
+#### 2.5 实施执行 (`/implement`)
+
+```bash
+# 开始实施
+/implement
+```
+
+### Phase 3: 库优先开发模式 📚
+
+#### 3.1 每个Feature必须首先创建独立库
+
+```typescript
+// 示例: HTTP Client库结构
+libs/http-client/
+├── src/
+│   ├── core/
+│   │   ├── HttpClient.ts       # 核心HTTP客户端
+│   │   ├── ProxyManager.ts     # 代理管理
+│   │   └── CredentialMatcher.ts # 凭证匹配
+│   ├── adapters/
+│   │   ├── PacificaAdapter.ts  # Pacifica适配器
+│   │   └── BaseExchangeAdapter.ts # 基础适配器
+│   └── index.ts
+├── tests/
+│   ├── unit/                   # 单元测试(真实环境)
+│   ├── integration/            # 集成测试
+│   └── contracts/              # 契约测试
+├── package.json
+└── README.md
+```
+
+#### 3.2 应用层集成
+
+```typescript
+// src/ 中只进行库的集成和配置
+import { HttpClient } from '@libs/http-client'
+import { CredentialManager } from '@libs/credential-manager'
+
+// 配置和使用，不包含业务逻辑
+const client = new HttpClient({
+  credentialManager: new CredentialManager(config),
+  proxy: proxyConfig
+})
+```
+
+### Phase 4: 质量保证体系 🛡️
+
+#### 4.1 测试策略 (遵循宪章原则一)
+
+```bash
+# 优先真实环境测试
+tests/
+├── unit/              # 真实数据库测试
+├── integration/       # 实际服务测试
+├── contracts/         # API契约测试
+└── e2e/              # 端到端真实场景
+```
+
+#### 4.2 Feature依赖检查
+
+```bash
+# 开发前检查
+.specify/scripts/check-feature-dependencies.sh
+
+# 合并前验证
+.specify/scripts/pre-merge-consistency-check.sh <feature-branch>
+```
+
+### Phase 5: 实际开发流程示例 🚀
+
+#### 5.1 创建第一个Feature: HTTP客户端库
+
+```bash
+# Step 1: 规格定义
+/specify "创建可扩展的多平台HTTP客户端库，支持智能凭证匹配和代理切换，首先实现Pacifica集成"
+
+# Step 2: 创建feature分支
+git checkout -b 001-http-client-lib
+
+# Step 3: 生成计划和任务
+/plan
+/tasks
+
+# Step 4: 开始库优先实施
+mkdir -p libs/http-client
+cd libs/http-client
+npm init -y
+
+# Step 5: 遵循TDD，先写契约测试
+mkdir -p tests/contracts
+# ... 契约测试编写
+
+# Step 6: 实施核心库
+# ... 核心逻辑开发
+
+# Step 7: 应用层集成
+# ... src/中集成使用
+
+# Step 8: 一致性检查
+.specify/scripts/pre-merge-consistency-check.sh 001-http-client-lib
+
+# Step 9: 合并到main
+git checkout main && git merge --no-ff 001-http-client-lib
+```
+
+---
+

+# 数据模型设计：凭证管理模块
+
+**特性**：001-credential-manager
+**日期**：2025-09-28
+**状态**：Phase 1 - 数据模型设计
+
+## 核心实体模型
+
+### 1. Platform（平台）
+
+**描述**：代表不同的交易平台，定义了特定的签名和认证规则。
+
+**属性**：
+- `id`: string - 平台唯一标识符
+- `name`: string - 平台显示名称
+- `signatureType`: SignatureType - 签名算法类型
+
+**枚举值**：
+```typescript
+enum Platform {
+  PACIFICA = 'pacifica',
+  ASTER = 'aster',
+  BINANCE = 'binance'
+}
+
+enum SignatureType {
+  ED25519 = 'ed25519',
+  ECDSA_ETHEREUM = 'ecdsa-ethereum',
+  HMAC_SHA256 = 'hmac-sha256'
+}
+```
+
+**验证规则**：
+- id必须是有效的平台枚举值
+- name不能为空
+- signatureType必须与平台匹配
+
+---
+
+### 2. Account（账户）
+
+**描述**：包含账户ID、平台类型、凭证信息的基本数据结构。
+
+**属性**：
+```typescript
+interface Account {
+  id: string;                    // 账户唯一ID
+  platform: Platform;           // 所属平台
+  credentials: Credentials;      // 凭证信息
+  metadata?: {                   // 可选元数据
+    alias?: string;              // 账户别名
+    description?: string;        // 账户描述
+    [key: string]: any;         // 其他自定义字段
+  };
+}
+```
+
+**凭证结构**：
+```typescript
+type Credentials = PacificaCredentials | AsterCredentials | BinanceCredentials;
+
+interface PacificaCredentials {
+  type: 'pacifica';
+  privateKey: string;            // 64字符十六进制Ed25519私钥
+}
+
+interface AsterCredentials {
+  type: 'aster';
+  privateKey: string;            // 以太坊格式私钥
+}
+
+interface BinanceCredentials {
+  type: 'binance';
+  apiKey: string;               // API密钥
+  secretKey: string;            // 密钥对
+}
+```
+
+**验证规则**：
+- id在所有账户中必须唯一
+- platform必须是有效的Platform枚举值
+- credentials类型必须与platform匹配
+- Pacifica私钥必须是64字符十六进制字符串
+- Aster私钥必须是以太坊格式（0x前缀）
+- Binance API密钥不能为空
+
+---
+
+### 3. Signer（签名器）
+
+**描述**：提供统一签名接口的组件，内部根据平台类型调用对应算法。
+
+**接口定义**：
+```typescript
+interface Signer {
+  // 统一签名接口
+  sign(accountId: string, message: Uint8Array): Promise<SignResult>;
+
+  // 验证签名
+  verify(accountId: string, message: Uint8Array, signature: string): Promise<boolean>;
+
+  // 获取账户信息
+  getAccount(accountId: string): Account | null;
+
+  // 列出所有账户
+  listAccounts(): Account[];
+}
+
+interface SignResult {
+  success: boolean;
+  signature?: string;           // Base64编码的签名
+  algorithm: string;           // 使用的签名算法
+  timestamp: Date;             // 签名时间戳
+  error?: string;              // 错误信息
+}
+```
+
+**平台特定签名策略**：
+```typescript
+interface SignerStrategy {
+  platform: Platform;
+  sign(message: Uint8Array, credentials: Credentials): Promise<string>;
+  verify(message: Uint8Array, signature: string, publicKey: string): Promise<boolean>;
+}
+```
+
+---
+
+### 4. ConfigLoader（配置加载器）
+
+**描述**：负责从配置文件加载账户信息并监听文件变更。
+
+**接口定义**：
+```typescript
+interface ConfigLoader {
+  // 加载配置文件
+  loadConfig(filePath: string): Promise<LoadResult>;
+
+  // 开始监听文件变更
+  watchConfig(filePath: string, callback: (accounts: Account[]) => void): void;
+
+  // 停止监听
+  stopWatching(): void;
+}
+
+interface LoadResult {
+  success: boolean;
+  accounts: Account[];
+  errors?: string[];
+  loadTime: number;            // 加载耗时（毫秒）
+}
+```
+
+**配置文件格式**：
+```typescript
+interface ConfigFile {
+  version: string;             // 配置文件版本
+  accounts: AccountConfig[];
+}
+
+interface AccountConfig {
+  id: string;
+  platform: Platform;
+  credentials: Credentials;
+  metadata?: Record<string, any>;
+}
+```
+
+---
+
+## 实体关系图
+
+```
+ConfigLoader (1) ←→ (N) Account
+    ↓
+Account (N) ←→ (1) Signer
+    ↓
+Signer (1) ←→ (N) SignerStrategy
+    ↓
+SignerStrategy (N) ←→ (1) Platform
+```
+
+**关系说明**：
+1. ConfigLoader加载多个Account
+2. Signer管理多个Account
+3. Signer使用多个SignerStrategy（按平台）
+4. 每个SignerStrategy对应一个Platform
+
+---
+
+## 状态变化流程
+
+### 配置文件生命周期
+```
+[文件创建] → [首次加载] → [监听变更] → [热重载] → [验证] → [更新内存]
+     ↓         ↓          ↓         ↓        ↓         ↓
+   CREATED → LOADING → WATCHING → RELOADING → VALIDATED → UPDATED
+```
+
+### 账户状态管理
+```typescript
+enum AccountStatus {
+  LOADING = 'loading',      // 正在加载
+  ACTIVE = 'active',        // 活跃可用
+  ERROR = 'error',          // 错误状态
+  REMOVED = 'removed'       // 已移除
+}
+```
+
+**状态转换规则**：
+- LOADING → ACTIVE：凭证验证成功
+- ACTIVE → ERROR：签名失败或凭证无效
+- ANY → REMOVED：从配置文件中删除
+- ERROR → ACTIVE：问题解决后重新验证
+
+---
+
+## JSON配置格式

+## 错误处理模型
+
+### 错误分类
+```typescript
+enum ErrorType {
+  CONFIG_LOAD_ERROR = 'config_load_error',
+  VALIDATION_ERROR = 'validation_error',
+  SIGNATURE_ERROR = 'signature_error',
+  PLATFORM_DETECTION_ERROR = 'platform_detection_error'
+}
+
+interface CredentialError {
+  type: ErrorType;
+  message: string;
+  accountId?: string;
+  timestamp: Date;
+  details?: any;
+}
+```
+
+### 错误处理策略
+- **配置加载错误**：记录错误，跳过无效账户，继续加载其他账户
+- **验证错误**：标记账户为ERROR状态，不影响其他账户
+- **签名错误**：返回错误结果，记录日志，不影响后续操作
+- **平台识别错误**：使用默认策略或手动指定平台

+
+## 总结
+基于现有的交易系统实现，需要构建一个凭证管理模块，支持多平台账户（Pacifica、Aster、Binance）的热加载、智能平台识别和统一签名接口。该模块将作为独立库提供给其他交易模块使用，确保符合库优先架构原则。
+
+**关键需求**：
+- FR-001: 配置文件热加载（<100ms）
+- FR-002: 智能平台识别
+- FR-003: 统一签名接口（<50ms）
+- FR-004: 账户信息查询
+
+**技术方案**：基于现有TypeScript 5.1+基础架构，使用@noble/ed25519实现Ed25519签名，Node.js fs.watch实现热加载，策略模式支持多平台扩展。
+
+## 技术背景
+**语言/版本**： TypeScript 5.1+，Node.js 18+
+**主要依赖**： @noble/ed25519，@noble/hashes，Jest
+**存储**： JSON配置文件，内存缓存
+**测试框架**： Jest，ts-jest
+**目标平台**： Node.js服务端，Linux/macOS
+**项目类型**： 独立库模块（支持其他交易模块）
+**性能目标**： 文件加载<100ms，签名操作<50ms
+**约束条件**： 热加载支持，多平台兼容，类型安全
+**规模/范围**： 支持数百个账户，3个主要平台（可扩展）
+
+## 宪章核对（Constitution Check）
+*关卡：必须在 Phase 0 前通过，并在 Phase 1 后再次确认。*
+
+### 原则一：库优先架构与现实测试
+- ✅ **库优先**：凭证管理器将作为独立npm库实现于`libs/credential-manager/`
+- ✅ **现实测试**：使用真实Ed25519签名算法和实际文件系统监听，避免模拟
+- ✅ **契约测试**：实施前编写失败的契约测试确保接口正确性
+
+### 原则二：Delta中性优先
+- ✅ **适用性**：凭证管理模块不直接涉及交易执行，但为交易模块提供安全签名服务
+- ✅ **风险控制**：确保私钥安全存储和签名操作的正确性，防止签名错误导致意外交易
+
+### 原则三：确定性市场数据摄取
+- N/A：凭证管理模块不涉及市场数据
+
+### 原则四：资金保护与风险控制
+- ✅ **账户安全**：实施严格的凭证验证和错误处理，防止无效签名
+- ✅ **操作审计**：记录所有签名操作和账户管理操作
+
+### 原则五：透明可观测性与审计
+- ✅ **结构化日志**：记录账户加载、签名操作、错误处理的详细日志
+- ✅ **性能监控**：追踪文件加载和签名操作性能指标
+- ✅ **端到端追踪**：为每个操作提供关联ID

+
+**结构决策**：采用独立库架构，符合宪章的库优先原则。该库可以被主项目和其他模块独立引用，提供完整的凭证管理功能。
+
+## Phase 0：概述与调研
+1. **从技术背景提取未知项**：
+   - 每个 NEEDS CLARIFICATION → 研究任务
+   - 每个新依赖 → 最佳实践任务
+   - 每个外部集成 → 设计模式任务
+2. **生成调研任务**：
+   ```
+   对每个未知项：
+     任务：调研 {未知点} 在 {功能背景} 的最佳做法
+   对每个技术选项：
+     任务：收集 {技术} 在 {领域} 的最佳实践
+   ```
+3. **整理输出**至 `research.md`：
+   - 决策：选择方案
+   - 理由：为何选择
+   - 备选：评估过的其他方案
+
+**产出**：research.md，所有未知项已解决
+
+## Phase 1：设计与契约
+*前提：research.md 已完成*
+
+1. **从功能规范提取实体** → `data-model.md`
+   - 实体名称、字段、关系
+   - 验证规则
+   - 状态变化若有
+2. **从需求生成 API 契约**
+   - 每个用户行为 → 对应接口
+   - REST/GraphQL 等标准格式
+   - 输出到 `/contracts/`
+3. **从契约生成契约测试**
+   - 每个接口一个测试文件
+   - 校验请求/响应结构
+   - 测试必须先失败
+4. **从用户故事提取测试场景**
+   - 每个故事 → 集成测试场景
+   - Quickstart 测试 = 验收步骤
+5. **增量更新 agent 文件**（O(1) 操作）：
+   - 运行 `.specify/scripts/bash/update-agent-context.sh claude`
+   - 仅添加本轮新增技术信息
+   - 保留手工补充内容
+   - 记录最近 3 次变更
+   - 保持文件在 150 行以内
+
+**产出**：data-model.md、/contracts/*、失败的契约测试、quickstart.md、更新后的 agent 文件
+
+## Phase 2：任务规划方法
+*说明 /tasks 命令的工作方式（本阶段不执行）*
+
+**任务生成策略**：
+- 以 `.specify/templates/tasks-template.md` 为基线
+- 根据 Phase 1 文档（契约、数据模型、quickstart）生成任务
+
+**从契约生成的任务**：
+- 每个接口契约 → 契约测试任务 [P]（必须先失败）
+- ICredentialManager → credential-manager契约测试
+- IConfigLoader → config-loader契约测试
+- ISigner → signer契约测试
+- IPlatformDetector → platform-detector契约测试
+
+**从数据模型生成的任务**：
+- 每个核心实体 → 模型创建任务 [P]
+- Platform、Account、Credentials → types.ts实现
+- SignResult、LoadResult → 结果类型实现
+- CredentialManagerError → 错误处理实现
+
+**从quickstart生成的任务**：
+- 每个示例场景 → 集成测试任务
+- 基础使用 → 基础功能集成测试
+- 签名操作 → 签名流程集成测试
+- 热加载监听 → 文件监听集成测试
+- 多平台签名 → 平台策略集成测试
+
+**库优先架构任务**：
+- 独立库结构创建
+- package.json配置
+- TypeScript配置
+- Jest测试配置
+- 构建和发布配置
+
+**TDD实现顺序**：
+1. 测试先行：所有契约测试必须先失败
+2. 核心模型：types → Account → Signer
+3. 平台策略：PacificaSigner → AsterSigner → BinanceSigner
+4. 服务层：ConfigLoader → PlatformDetector → CredentialManager
+5. 工厂和集成：CredentialManagerFactory → 全局管理器
+6. 验证和优化：性能测试 → 错误处理 → 生产优化
+
+**依赖关系管理**：
+- [P] 标记并行任务（不同文件，无依赖）
+- 严格按照 types → 实现 → 集成 → 验证 顺序
+- Ed25519库集成必须在Pacifica实现之前
+- 配置文件监听必须在热加载测试之前
+
+**预估输出**：
+- tasks.md：约30-35个有序任务
+- 5个主要阶段：Setup → Tests → Core → Integration → Polish
+- 符合库优先架构和现实测试原则
+
+**性能验证任务**：
+- 文件加载<100ms验证
+- 签名操作<50ms验证
+- 内存使用监控
+- 并发操作测试
+
+**注意**：Phase 2 由 /tasks 完成，非 /plan 输出
+
+## Phase 3+：后续实施
+*超出 /plan 命令范围*
+
+**Phase 3**：执行 /tasks 生成 tasks.md  
+**Phase 4**：按 tasks.md 实施  
+**Phase 5**：验证（运行测试、执行 quickstart、性能验证）
+

+      }
+    }
+  ]
+}
+```
+
+## 快速开始示例
+
+### 示例1：基础使用
+
+```typescript
+import { CredentialManagerFactory } from '@your-org/credential-manager';
+
+async function basicUsage() {
+  // 1. 创建凭证管理器
+  const factory = new CredentialManagerFactory();
+  const manager = await factory.create({
+    enableFileWatching: true,
+    enableLogging: true
+  });
+
+  // 2. 加载配置文件
+  const result = await manager.loadConfig('./config/accounts.json');
+  console.log(`加载成功: ${result.accounts.length} 个账户`);
+
+  // 3. 列出所有账户
+  const accounts = manager.listAccounts();
+  accounts.forEach(account => {
+    console.log(`账户: ${account.id} (${account.platform})`);
+  });
+
+  // 4. 获取特定账户
+  const account = manager.getAccount('pacifica-main-001');
+  if (account) {
+    console.log(`找到账户: ${account.metadata?.alias}`);
+  }
+
+  return manager;
+}
+```
+
+### 示例2：签名操作
+
+```typescript
+async function signingExample(manager) {
+  // 1. 准备要签名的消息
+  const message = new TextEncoder().encode('Hello, Pacifica!');
+
+  // 2. 执行签名 (系统自动识别平台类型)
+  const signResult = await manager.sign('pacifica-main-001', message);
+
+  if (signResult.success) {
+    console.log('签名成功:', {
+      signature: signResult.signature,
+      algorithm: signResult.algorithm,
+      timestamp: signResult.timestamp
+    });
+
+    // 3. 验证签名
+    const isValid = await manager.verify('pacifica-main-001', message, signResult.signature!);
+    console.log('签名验证:', isValid ? '通过' : '失败');
+  } else {
+    console.error('签名失败:', signResult.error);
+  }
+
+  return signResult;
+}
+```
+
+### 示例3：热加载监听
+
+```typescript
+async function hotReloadExample(manager) {
+  // 1. 开始监听配置文件变更
+  manager.watchConfig('./config/accounts.json', (accounts) => {
+    console.log(`配置文件已更新，重新加载了 ${accounts.length} 个账户`);
+
+    accounts.forEach(account => {
+      console.log(`- ${account.id}: ${account.platform} (${account.status})`);
+    });
+  });
+
+  console.log('开始监听配置文件变更...');
+  console.log('现在可以修改 accounts.json 文件来测试热加载功能');
+
+  // 2. 模拟运行一段时间
+  await new Promise(resolve => setTimeout(resolve, 30000));
+
+  // 3. 停止监听
+  manager.stopWatching();
+  console.log('停止监听配置文件变更');
+}
+```
+
+### 示例4：多平台签名
+
+```typescript
+async function multiPlatformExample(manager) {
+  const testMessage = new TextEncoder().encode('多平台测试消息');
+
+  // 获取所有账户并按平台分组
+  const accounts = manager.listAccounts();
+  const platformGroups = accounts.reduce((groups, account) => {
+    if (!groups[account.platform]) {
+      groups[account.platform] = [];
+    }
+    groups[account.platform].push(account);
+    return groups;
+  }, {} as Record<string, any[]>);
+
+  // 为每个平台的每个账户执行签名
+  for (const [platform, platformAccounts] of Object.entries(platformGroups)) {
+    console.log(`\n=== ${platform.toUpperCase()} 平台签名测试 ===`);
+
+    for (const account of platformAccounts) {
+      try {

+          console.log(`✅ ${account.id}: 签名成功 (${duration}ms)`);
+          console.log(`   算法: ${result.algorithm}`);
+          console.log(`   签名: ${result.signature?.substring(0, 20)}...`);
+        } else {
+          console.log(`❌ ${account.id}: 签名失败 - ${result.error}`);
+        }
+      } catch (error) {
+        console.log(`💥 ${account.id}: 签名异常 - ${error.message}`);
+      }
+    }
+  }
+}
+```
+

+# Tasks: 凭证管理模块 (Credential Manager)
+
+**Input**: Design documents from `/specs/001-credential-manager/`
+**Prerequisites**: plan.md (required), research.md, data-model.md, contracts/
+
+## Execution Flow (main)
+```
+1. Load plan.md from feature directory
+   → Extract: TypeScript 5.1+, @noble/ed25519, Node.js fs.watch, strategy pattern
+   → Structure: libs/credential-manager/ (独立库实现)
+2. Load design documents:
+   → data-model.md: Platform, Account, Signer, ConfigLoader entities
+   → contracts/: credential-manager.ts, pacifica-signer.ts
+   → research.md: Ed25519签名库、文件监听、智能识别、统一接口
+3. Generate tasks by category:
+   → Setup: 库结构、依赖安装、@noble/ed25519
+   → Tests: 契约测试、集成测试、性能测试
+   → Core: 凭证管理器、平台检测器、签名器
+   → Integration: 文件监听、配置加载、错误处理
+   → Polish: 单元测试、性能验证、快速开始文档
+4. Apply TDD rules:
+   → 契约测试先行（必须失败）
+   → 不同文件标记[P]并行
+   → 签名操作<50ms、文件加载<100ms性能要求
+5. Number tasks sequentially (T001, T002...)
+6. Validate completeness: 所有契约有测试、所有实体有模型
+```

+## Dependencies
+- Setup (T001-T006) before everything
+- Tests (T007-T015) before implementation (T016-T029)
+- T016 blocks T017-T019 (types dependency)
+- T018 blocks T030-T031 (ConfigLoader dependency)
+- T019 blocks T020-T022 (detector interface dependency)
+- T023-T025 must complete before T026 (PacificaSigner dependency)
+- T026-T027 blocks T033 (signer dependency)
+- T029 blocks T035 (factory dependency)
+- Implementation before polish (T036-T044)
+
+## Parallel Example
+```
+# Launch contract tests T007-T010 together:
+Task: "Contract test ICredentialManager interface in libs/credential-manager/tests/contract/test_credential_manager.ts"
+Task: "Contract test IPacificaSigner interface in libs/credential-manager/tests/contract/test_pacifica_signer.ts"
+Task: "Contract test IConfigLoader interface in libs/credential-manager/tests/contract/test_config_loader.ts"
+Task: "Contract test ISigner interface in libs/credential-manager/tests/contract/test_signer.ts"
+
+# Launch platform detectors T020-T022 together:
+Task: "PacificaDetector strategy in libs/credential-manager/src/platforms/pacifica/PacificaDetector.ts"
+Task: "AsterDetector strategy in libs/credential-manager/src/platforms/aster/AsterDetector.ts"
+Task: "BinanceDetector strategy in libs/credential-manager/src/platforms/binance/BinanceDetector.ts"
+```
+
+## Notes
+- [P] tasks = different files, no dependencies
+- Verify contract tests fail before implementing
+- 库优先架构: 独立package.json in libs/credential-manager/
+- 性能要求: 签名<50ms, 文件加载<100ms
+- Ed25519签名使用@noble/ed25519库
+- 配置文件热加载使用Node.js fs.watch
+- 平台智能识别使用多重检测器模式
+
+## Task Generation Rules
+*Applied during main() execution*
+
+1. **From Contracts**:
+   - credential-manager.ts → ICredentialManager, IConfigLoader, ISigner contract tests [P]
+   - pacifica-signer.ts → IPacificaSigner contract test [P]
+
+2. **From Data Model**:
+   - Platform, Account, Signer → model creation tasks [P]
+   - ConfigLoader → file watching and validation tasks
+
+3. **From User Stories (quickstart.md)**:
+   - 基础使用 → account management integration test [P]
+   - 签名操作 → Pacifica signing integration test [P]
+   - 热加载监听 → hot loading integration test [P]
+   - 多平台签名 → platform detection integration test [P]
+
+4. **Ordering**:
+   - Setup → Tests → Models → Services → Integration → Polish
+   - 文件监听依赖ConfigLoader
+   - 签名器依赖平台检测器
+   - 工厂依赖所有核心组件
+
