-## 状态与流程概述
-1. **账户同步**：定期拉取交易所余额与仓位，更新 `ExchangeAccount` 与相关 `RiskEnvelope` 信息。
-2. **行情刷新**：`MarketDataFeed` 维护实时顺序；当 WS 异常时生成 `SynthPriceSnapshot` 并触发 `MonitoringEvent`。
-3. **信号生成**：`StrategyModule` 基于行情与账户状态生成 `OrderIntent`，并写入待执行队列。
-4. **对冲执行**：控制平面根据 Delta 与利用率状态，调度 `HedgeExecution`，创建或取消订单，保持在宪章阈值内。
-5. **观测与回溯**：所有关键操作写入 `MonitoringEvent`，日志保留 ≥90 天，可用于追溯与审计。

-## 总结
-- 构建一个可扩展的多交易所多账户控盘层，自动保持整体 Delta 中性，并让单账户资金利用率维持 50%-80%。  
-- 所有高频行情使用 WebSocket 实时刷新，主源失效 10 秒内必须切换备用；所有带权限的交互经代理执行。  
-- 框架需支持限价优先、对冲、资金费率套利、做市等策略模块，配套结构化观测与自动化测试保障。
-
-## 技术背景
-**语言/版本**：TypeScript 5.1 / Node.js 18.12  
-**主要依赖**：ws、axios、dotenv、winston、jest、tsx、https-proxy-agent、redis、sequelize 等  
-**存储**：当前以内存状态与外部交易所为主，无持久化数据库约束  
-**测试框架**：jest（含 ts-jest）、集成测试脚本  
-**目标平台**：Linux/容器化运行环境，需支持代理网络  
-**项目类型**：单一后端项目（多模块架构）  
-**性能目标**：行情刷新 <2s、控制循环 ≤8s、主源失效 ≤10s 完成回退  
-**约束条件**：所有敏感调用走代理；资金利用率 50%-80%；Delta 容忍 ±0.0005 BTC；止损路径 ≤30s；日志保留 ≥90 天  
-**规模/范围**：同时管理 ≥3 个交易所账户，支持新增策略模块与交易所扩展
-
-## 宪章核对（Constitution Check）
-- **原则 I：Delta-Neutral First** —— 计划中所有策略均以内外账户 Delta 为核心监控，设定再平衡与对冲流程，状态 PASS。  
-- **原则 II：Deterministic Market Data Intake** —— 行情层采用 WebSocket+HTTP 回退，明确 2s 新鲜度与 10s failover SLA，状态 PASS。  
-- **原则 III：Capital Protection & Risk Controls** —— 监控资金利用率、止损、利用率越界触发回滚；30s 内完成紧急对冲，状态 PASS。  
-- **原则 IV：Transparent Observability & Audit** —— 设计阶段将补充统一日志、指标、健康检查与事件追踪，状态 PASS。  
-- **原则 V：Tested Execution Paths** —— 在计划中安排 Dry-run、双账户集成测试、回退场景测试，状态 PASS。  
-- **运营约束**：≤8s 循环、代理网络、密钥轮换、日志保留要求已纳入研究与实施任务。  
-- **流程质量门槛**：plan/research/data-model/quickstart 均需映射宪章要点；PR 需附带日志或测试佐证。  
-- **治理要求**：遵循 SemVer 及每月合规复核；本计划中为后续 /tasks 与 PR 审查提供依据。

-# Quickstart 测试指南：多平台 Delta 中性控制平面
-
-## 前置条件
-1. 已配置至少 2 个 Pacifica 账户与 1 个 Aster 账户，所有凭证通过代理可用。  
-2. 行情服务已连接 WebSocket，且 HTTP 备份正常。  
-3. 策略模块启用 Dry-run 模式以便验证。
-
----
-
-## 场景 1：资金利用率低于 50% 自动补仓
-1. 启动控制平面与行情服务。  
-2. 将 pacifica-1 账户的可用余额调高，使利用率 <0.5。  
-3. 观察系统在 8 秒内生成限价买单，并通过对冲维持 Delta≈0。  
-4. 验证仪表盘显示利用率回到 50% 附近，并记录 `MonitoringEvent`。
-
-### 验证
-- 日志中出现 `utilization-low` 告警与后续恢复记录。  
-- `HedgeExecution` 结果成功且 Delta 偏差 < ±0.0005 BTC。
-
----
-
-## 场景 2：行情主源失效 10 秒内回退
-1. 手动断开 pacifica WebSocket 连接。  
-2. 确认 2 秒内触发 `market-data-failover` 事件，切换到 HTTP 拉取。  
-3. 在 10 秒内恢复交易，并打印合成价格或备用价格。  
-4. 重新连接 WebSocket，确保系统回归正常状态。
-
-### 验证
-- 日志出现 `market-data-failover-complete`，用时 < 10000ms。  
-- 交易模块暂停新订单期间未引发额外对冲。
-
----
-
-## 场景 3：Delta 偏离自动对冲
-1. 人为向 pacifica-1 下达市价单，造成 Delta 偏离 0.001 BTC。  
-2. 控制平面应立即生成跨账户对冲指令，将 Delta 拉回 0。  
-3. 记录 `HedgeExecution` 成功，duration < 30 秒。  
-4. 查看仪表盘，确认利用率未越界且止损策略保持有效。
-
-### 验证
-- `HedgeExecution` 详情包含两笔对冲订单全部成交。  
-- 监控事件记录 `delta-breach` 与恢复信息。
-
----
-
-## 场景 4：策略模块沙箱验证
-1. 以 Dry-run 模式启动新策略模块（例如资金费率套利）。  
-2. 向系统推送模拟资金费率信号，生成配对多空订单但仅写入虚拟撮合器。  
-3. 验证模拟订单与真实行情一致，并在 quickstart 中记录收益计算。  
-4. 完成后查看 Dry-run 报告与日志，确认无真实下单行为。
-
-### 验证
-- 日志标记 `sandbox-execution`，订单状态保持虚拟。  
-- Profit-after-fee 计算结果记录在报告中。
-
----
-
-## 清理步骤
-1. 恢复所有代理与行情连接。  
-2. 取消 Dry-run 模式并关闭策略模块。  
-3. 将测试中下发的订单撤销，恢复账户余额。  
-4. 汇总日志、监控事件以备审计或进一步分析。

-# Phase 0 调研记录：多平台 Delta 中性控制平面
-
-## 调研目标概览
-- 设计多层行情回退策略（WebSocket → HTTP → 合成价格），满足 10 秒内恢复交易的 SLA。
-- 明确资金利用率 50%-80% 边界的测量方式与触发流程。
-- 评估跨交易所 Delta 对冲与风险指标的实现方案。
-- 优化代理网络与凭证隔离方案，保障高频请求的稳定性。
-- 设计可插拔策略模块的接口标准与沙箱验证路径。
-
-## 调研成果
-
-### 1. 行情回退与 Failover
-- **决策**：
-  - 主通道使用各交易所官方 WebSocket；为每个交易所配置 HTTP 深度接口作为同步回退。
-  - 当 WebSocket 数据陈旧 >2 秒或连接失败时，立即拉取 HTTP 深度并触发告警；若连续 3 次 HTTP 拉取失败，则使用最近 30 秒的中位价合成报价。
-  - 整个切换流程需在 10 秒内完成，恢复后需重新验证 Delta 中性状态并记录日志。
-- **理由**：
-  - WebSocket 具备低延迟、高频刷新能力；HTTP 拉取可覆盖短暂断线；合成报价保障交易不中断。
-  - 10 秒 SLA 与宪章和 Spec 要求一致，可最大限度降低刷量中断时间。
-- **备选方案**：
-  - 仅使用 WebSocket + 缓存（被否决：主源断开时无法迅速获得新数据）。
-  - 引入第三方行情聚合（被否决：依赖额外服务且增加成本与延迟）。
-
-### 2. 资金利用率与再平衡策略
-- **决策**：
-  - 利用率公式：（账户总余额 − 可用余额）÷ 账户总余额；当利用率 <50% 触发开仓增加持仓，当 >80% 触发行权/平仓释放保证金。
-  - 再平衡流程：
-    1. 计算账户利用率与 Delta；若利用率越界且 Delta 允许，则优先调整限价单队列；
-    2. 若越界同时 Delta 偏离 ±0.0005 BTC 等值，则优先执行对冲单恢复 Delta，再处理限价单；
-    3. 整个流程需要在 8 秒内完成一次评估循环。
-- **理由**：
-  - 采用账户余额视角衡量利用率，更贴近资金占用情况，与用户澄清一致。
-  - 将 Delta 调整优先级置于利用率之前，可避免为满足利用率而放大风险敞口。
-- **备选方案**：
-  - 使用保证金占用 / 可用保证金，需依赖交易所差异化字段，不易统一；
-  - 在利用率越界时直接使用市价单（被否决：可能血亏且不符合“限价优先”策略）。
-
-### 3. Delta 中性与风险指标
-- **决策**：
-  - 统一使用 BTC 等值作为敞口度量单位；针对非 BTC 交易对，按实时价格折算。
-  - 设定 Delta 容忍区间 ±0.0005 BTC 等值；超过阈值立即触发对冲交易（跨账户或跨交易所）。
-  - 将风险指标拆分为：净敞口、未实现 PnL、利用率、滑点预估、止损执行时间。
-- **理由**：
-  - BTC 等值便于比较不同交易所、不同币种的敞口。
-  - 分层指标可支持仪表盘和告警联动，符合宪章中的透明可观测性要求。
-- **备选方案**：
-  - 为每个币种单独设定阈值（维护成本高，且对冲策略复杂）。
-
-### 4. 代理网络与凭证隔离
-- **决策**：
-  - 所有带权限的 HTTP 请求通过授权代理池（支持账号隔离与 Session 轮换）。
-  - WebSocket 在可行的情况下直连，若交易所限制需走代理，则为特定账户配置独立代理通道。
-  - 凭证存储采用加密文件 + 内存热加载；密钥轮换脚本每季度复测。
-- **理由**：
-  - 代理池保障来源 IP 多样性并隔离账号风险；限定关键请求经代理符合用户“防止女巫”要求。
-  - 区分 HTTP 与 WS 代理策略能兼顾性能与稳定性。
-- **备选方案**：
-  - 所有网络流量都走代理（被否决：行情延迟大，且部分交易所对 WS 代理支持不佳）。
-
-### 5. 策略模块接口与沙箱
-- **决策**：
-  - 定义策略模块对外接口：`init(config)`、`generateSignals(state)`、`onFill(event)`、`onRiskAlert(alert)`。
-  - 沙箱模式：提供 Dry-run 仿真环境，使用真实行情与订单簿，但所有下单写入虚拟撮合引擎；成功通过后才可接入生产。
-  - 新策略上线需提供 profit-after-fee 模型与回退方案，自动化测试需要覆盖 signal 生成、下单、撤单、对冲流程。
-- **理由**：
-  - 统一接口有利于增量扩展；沙箱保障策略安全上线；测试要求与宪章 Principle V 对齐。
-- **备选方案**：
-  - 策略模块直接依赖底层 TradeExecutor API（被否决：耦合度高且不利于未来维护）。
-
-## 待跟进事项
-- 针对资金费率套利策略，需要在 Phase 1 中明确长期仓位的资金费率聚合逻辑。
-- 确认各交易所 WebSocket 心跳与鉴权细节，填入 contracts/ 中的订阅契约。
-- 研究行情合成时的精度处理，确定是否需要简单移动平均或加权中位数（Phase 1 data-model.md 中补充）。
-

-- Aster DEX 文档（WebSocket、订单簿订阅）
-- Binance Futures API 速率限制说明
-- 现有仓库中的 `docs/PRICE_MANAGEMENT_SOLUTION.md` 与 `docs/ASTER_TESTS.zh.md`

-## 用户场景与测试（必填）
-
-### 核心用户故事
-多平台对冲控制器在多个交易所、多个账户之间维护整体 Delta 接近零，并保证每个账户的资金利用率稳定在 50%-80% 之间；即便高频策略持续发出限价单以提升真实成交量，也能在手续费后保持盈利。
-
-### 验收场景
-1. **给定** pacifica-1/2 与 aster-1 账户利用率降到 50% 以下，**当** 控制器评估敞口时，**则** 会通过代理发起限价单，将利用率恢复到约 50%，同时保持整体 Delta 在 ±0.0005 BTC 等值内。  
-2. **给定** binance 与 pacifica 的订单簿通过 WebSocket 正常刷新，**当** pacifica 数据陈旧超过 2 秒时，**则** 系统必须切换到 HTTP 深度、发出告警，并在数据恢复之前暂停新交易。  
-3. **给定** 部分成交导致 Delta 失衡，**当** 控制平面执行再平衡时，**则** 会跨可用交易所/账户路由对冲订单，重新拉回 Delta 中性，并重新设置成对止损/止盈。  
-4. **给定** 新策略模块（做市、资金费率套利）接入，**当** 它们申请账户配额时，**则** 框架会在利用率、代理路由、现有对冲承诺之间自动分配，保证不中断。  
-5. **给定** 主行情源突然失效，**当** 备用行情在 10 秒内完成切换时，**则** 交易可恢复且继续维持 Delta 中性与风险控制。
-
-### 边界与异常
-- 行情数据过期或不可用时的处理策略。  
-- 流动性不足、代理链路故障、部分成交的处理方式。  
-- 交易所停机或账户冻结期间如何维持 Delta 中性。  
-- 限价单长时间未成交的应对流程。  
-- 主行情源在 10 秒内无法完成切换的应急策略。
-
-## 功能需求（必填）

-# Tasks: 多平台 Delta 中性控制平面
-
-**Input**: Design documents from `/specs/001-specManager-perp/`
-**Prerequisites**: plan.md (required), research.md, data-model.md, contracts/
-
-## Execution Flow (main)
-```
-1. Load plan.md from feature directory
-   → If not found: ERROR "No implementation plan found"
-   → Extract: tech stack, libraries, structure
-2. Load optional design documents:
-   → data-model.md: Extract entities → model tasks
-   → contracts/: Each file → contract test task
-   → research.md: Extract decisions → setup tasks
-3. Generate tasks by category:
-   → Setup: environment, proxies, credentials, risk configs
-   → Tests: dry-run simulations, orderbook validation, multi-account integration
-   → Core: hedging engines, order routing, exposure monitoring
-   → Integration: exchange adapters, observability, rollback safeguards
-   → Polish: performance verification, documentation, operational rehearsals
-4. Apply task rules:
-   → Different files = mark [P] for parallel
-   → Same file = sequential (no [P])
-   → Tests before implementation (TDD)
-   → Exposure-related safeguards MUST precede new trading flows
-5. Number tasks sequentially (T001, T002...)
-6. Generate dependency graph
-7. Create parallel execution examples
-8. Validate task completeness:
-   → All contracts have tests?
-   → All entities have models?
-   → All endpoints implemented?
-9. Return: SUCCESS (tasks ready for execution)

-# 数据模型：多平台账户凭据管理与签名服务
-
-## 核心实体设计（简化版）
-
-### 1. PlatformAccount (平台账户)
-
-存储各平台的账户凭据信息，支持不同平台的凭据格式。
-
-```typescript
-interface PlatformAccount {
-  accountId: string;           // 账户唯一标识
-  platformId: 'pacifica' | 'aster' | 'binance' | 'okx';
-  alias?: string;              // 账户别名
-
-  // 加密存储的凭据（根据平台不同）
-  credentials: {
-    // Pacifica: Ed25519 私钥
-    privateKey?: string;       // base58 编码
-
-    // Aster: 以太坊私钥 + 签名者地址
-    ethPrivateKey?: string;    // 0x 开头
-    signerAddress?: string;    // 0x 开头
-
-    // Binance/OKX: API 凭据
-    apiKey?: string;
-    secretKey?: string;
-    passphrase?: string;       // OKX 需要
-  };
-
-  // 状态信息
-  status: 'active' | 'inactive';
-  environment: 'development' | 'production';
-
-  // 使用统计
-  usage: {
-    totalSigns: number;
-    lastSignAt?: Date;
-    errorCount: number;
-  };
-
-  createdAt: Date;
-  updatedAt: Date;
-}
-```
-
-### 2. SignatureAdapter (签名适配器)
-
-为每个平台实现特定的签名算法。
-
-```typescript
-interface SignatureAdapter {
-  platformId: string;         // 平台标识
-  algorithm: 'ed25519' | 'eip191' | 'hmac-sha256';
-
-  // 签名方法
-  sign(data: any, credentials: any): Promise<SignatureResult>;
-
-  // 验证方法（可选）
-  verify?(signature: string, data: any, publicKey: string): Promise<boolean>;
-}
-
-interface SignatureResult {
-  signature: string;
-  algorithm: string;
-  encoding: string;           // base58, hex, base64
-  publicKey?: string;         // 如果适用
-  metadata?: Record<string, any>;
-}
-```
-
-### 3. ConfigManager (配置管理器)
-
-管理配置文件的加载和热重载。
-
-```typescript
-interface ConfigManager {
-  configPath: string;
-  lastLoaded: Date;
-
-  // 加载的账户数据
-  accounts: Map<string, PlatformAccount>; // key: platformId:accountId
-
-  // 配置操作
-  loadConfig(): Promise<void>;
-  reloadConfig(): Promise<void>;
-  watchConfig(): void;        // 监控文件变化
-
-  // 账户查询
-  getAccount(platformId: string, accountId: string): PlatformAccount | null;
-  getAccountsByPlatform(platformId: string): PlatformAccount[];
-}
-```
-
-## 配置文件格式
-
-### JSON 配置结构
-```json
-{
-  "pacifica": [
-    {
-      "accountId": "pac-main-001",
-      "alias": "Pacifica主账户",
-      "privateKey": "base58_encoded_private_key",
-      "environment": "production"
-    }
-  ],

-      "passphrase": "your_passphrase",
-      "environment": "production"
-    }
-  ]
-}
-```
-
-## 核心服务接口
-
-### CredentialManager (主服务)
-```typescript
-interface CredentialManager {
-  // 签名服务（核心功能）
-  sign(platformId: string, accountId: string, data: any): Promise<SignatureResult>;
-
-  // 账户查询
-  getAccount(platformId: string, accountId: string): PlatformAccount | null;
-  listAccounts(platformId?: string): PlatformAccount[];
-
-  // 配置管理
-  reloadConfig(): Promise<void>;

-}
-
-interface ConfigStatus {
-  configPath: string;
-  lastLoaded: Date;
-  accountCount: number;
-  platformCount: number;
-  isWatching: boolean;
-}
-```
-
-## 验证规则
-
-### 1. 账户标识验证
-- `accountId`: 3-50字符，字母数字和连字符
-- `platformId`: 必须是 'pacifica' | 'aster' | 'binance' | 'okx'
-
-### 2. 凭据格式验证
-- Pacifica privateKey: base58编码，44字符
-- Aster ethPrivateKey: 0x开头，64位十六进制
-- Binance/OKX apiKey: 非空字符串
-- Binance/OKX secretKey: 非空字符串
-
-### 3. 环境隔离
-- development 和 production 环境账户分离
-- 同一 platformId + accountId 组合唯一

-2. 填写技术背景（扫描 NEEDS CLARIFICATION）
-   → 根据文件结构或上下文判断项目类型（web=前后端，mobile=App+API）
-   → 根据项目类型给出结构决策
-3. 根据宪章内容完成 Constitution Check 部分（原则 I–V、运营约束、流程质量门槛、治理要求）
-4. 评估 Constitution Check
-   → 若存在违例：记录在 Complexity Tracking
-   → 若无法给出理由：ERROR "Simplify approach first"
-   → 更新 Progress Tracking：Initial Constitution Check
-5. 执行 Phase 0 → research.md（确保记录行情数据源、敞口目标与风险约束）
-   → 若仍有 NEEDS CLARIFICATION：ERROR "Resolve unknowns"
-6. 执行 Phase 1 → contracts、data-model.md、quickstart.md、agent 文件
-7. 再次评估 Constitution Check
-   → 若出现新违例：回到 Phase 1 调整
-   → 更新 Progress Tracking：Post-Design Constitution Check
-8. 规划 Phase 2 → 描述任务生成策略（不要创建 tasks.md）
-9. 停止 - 准备执行 /tasks 命令

-
-**结构决策**：采用简化的单体服务架构，专注于核心功能。credential-manager.ts 作为主服务，集成配置加载、账户管理和签名调度。signature-adapters/ 目录包含各平台的签名实现，保持良好的扩展性。
-
-## 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 cursor`
-   - 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**：
-基于简化设计文档生成实现任务：
-
-### 核心模块任务（基于 data-model.md）
-1. **数据模型层** [P]：
-   - PlatformAccount 实体实现
-   - SignatureAdapter 接口定义
-   - ConfigManager 配置管理器
-
-2. **签名适配器** [P]：
-   - PacificaAdapter: Ed25519 签名实现
-   - AsterAdapter: EIP-191 签名实现
-   - BinanceAdapter: HMAC-SHA256 签名实现
-   - OkxAdapter: OKX 特有签名实现
-
-### 契约测试任务（基于 contracts/）
-1. **签名服务契约** [P]: signature-service.md → 测试多平台签名和批量操作
-2. **配置管理契约** [P]: 配置加载、热重载、状态查询测试
-
-### 集成测试任务（基于 quickstart.md）
-1. **配置文件加载**: 多平台账户注入测试
-2. **Pacifica签名**: Ed25519 签名流程测试

-# 技术调研：多平台账户凭据管理与签名服务
-
-## 调研概述
-
-本文档分析多平台账户凭据管理系统的技术选型、签名算法最佳实践、配置管理方案和安全实现策略。
-
-## 关键技术决策
-
-### 1. 签名算法选型
-
-#### Pacifica (Solana 基础)
-**决策**: 使用 Ed25519 签名算法
-**理由**:
-- Pacifica 基于 Solana 区块链，原生支持 Ed25519
-- `tweetnacl` 库提供高性能 Ed25519 实现
-- `bs58` 库处理 base58 私钥编码
-- 与现有 Pacifica 集成完全兼容
-
-**备选方案**:
-- 直接使用 @solana/web3.js (过重，仅需签名功能)
-- libsodium (C binding，增加部署复杂度)
-
-#### Aster (以太坊基础)
-**决策**: 使用 EIP-191 签名方案
-**理由**:
-- Aster 基于以太坊，支持标准 EIP-191 个人签名
-- `ethers` 库提供完整的以太坊签名实现
-- 支持 keccak256 哈希和 secp256k1 椭圆曲线
-- 与现有 Aster 集成保持一致
-
-**备选方案**:
-- EIP-712 结构化签名 (复杂度过高，Aster 不需要)
-- 原始 secp256k1 签名 (缺乏标准化，兼容性差)
-
-#### Binance (CEX)
-**决策**: 使用 HMAC-SHA256 签名
-**理由**:
-- Binance 官方 API 要求 HMAC-SHA256
-- Node.js 内置 crypto 模块支持
-- 高性能，无需外部依赖
-- 标准化实现，维护成本低
-
-**备选方案**:
-- RSA 签名 (Binance 不支持)
-- HMAC-SHA1 (安全性不足，已弃用)
-
-#### OKX
-**决策**: 使用 HMAC-SHA256 + Base64 编码
-**理由**:
-- OKX 特有的三元组认证 (API Key + Secret + Passphrase)
-- 需要特定的请求头格式和时间戳处理
-- 使用标准 HMAC-SHA256 确保兼容性
-
-### 2. 配置文件格式选型
-
-#### JSON vs YAML vs TOML
-**决策**: 使用 JSON 格式
-**理由**:
-- Node.js 原生解析支持，无需额外依赖
-- 严格的数据类型定义，减少配置错误
-- 广泛的工具支持和调试能力
-- 与现有项目配置风格一致
-
-**备选方案评估**:
-```typescript
-// YAML: 人类友好但解析开销大
-yaml: require('yaml') // +50KB dependency
-
-// TOML: 新兴格式，生态不成熟
-toml: require('@iarna/toml') // +30KB dependency
-
-// JSON: 原生支持，零依赖
-json: JSON.parse() // Native
-```
-
-### 3. 热重载实现方案
-
-#### 文件系统监控技术
-**决策**: 使用 Node.js fs.watch API
-**理由**:
-- 原生支持，无需第三方依赖
-- 跨平台兼容 (Linux inotify, macOS fsevents, Windows NTFS)
-- 低延迟 (<100ms) 检测文件变化
-- 内存占用小，适合生产环境
-
-**实现策略**:
-```typescript
-// 智能防抖动：避免频繁重载
-const debounceTime = 1000; // 1秒防抖
-let reloadTimer: NodeJS.Timeout;
-
-fs.watch(configPath, (eventType, filename) => {
-  clearTimeout(reloadTimer);
-  reloadTimer = setTimeout(() => {
-    this.reloadCredentials();
-  }, debounceTime);
-});
-```
-
-**备选方案**:
-- `chokidar` 库 (功能强大但增加依赖)
-- 定时轮询 (延迟高，资源消耗大)
-
-### 4. 凭据加密存储方案
-
-#### 加密算法选择
-**决策**: 使用 AES-256-GCM
-**理由**:
-- AEAD (认证加密) 提供完整性保护
-- GCM 模式支持并行计算，性能优异
-- NIST 推荐标准，安全性经过验证
-- Node.js crypto 模块原生支持
-
-**实现细节**:
-```typescript
-// 密钥派生：PBKDF2 + 随机盐
-const salt = crypto.randomBytes(32);
-const key = crypto.pbkdf2Sync(password, salt, 100000, 32, 'sha256');
-
-// 加密：AES-256-GCM + 随机IV
-const iv = crypto.randomBytes(16);
-const cipher = crypto.createCipher('aes-256-gcm', key);
-```
-
-**备选方案**:
-- AES-256-CBC (需要额外的HMAC完整性验证)
-- ChaCha20-Poly1305 (性能好但兼容性差)
-
-### 5. 权限控制架构
-
-#### RBAC vs ABAC
-**决策**: 实现简化的平台级 RBAC
-**理由**:
-- 需求明确：模块对平台的访问控制
-- RBAC 实现简单，维护成本低
-- 满足当前<100 QPS的性能要求
-- 便于审计和调试
-
-**权限模型设计**:
-```typescript
-interface PermissionPolicy {
-  moduleId: string;           // 模块标识
-  allowedPlatforms: string[]; // 允许访问的平台
-  permissions: {
-    sign: boolean;            // 签名权限
-    query: boolean;           // 查询权限
-  };
-}
-```
-
-**备选方案**:
-- ABAC (基于属性) - 过于复杂，当前需求不需要
-- ACL (访问控制列表) - 扩展性差，不适合多平台
-
-### 6. 错误处理和重试策略
-
-#### 签名失败处理
-**决策**: 指数退避 + 熔断器模式
-**理由**:
-- 指数退避避免雪崩效应
-- 熔断器保护底层服务
-- 最大重试次数控制资源消耗
-
-**实现方案**:
-```typescript
-class SignatureService {
-  private async retryWithBackoff<T>(
-    operation: () => Promise<T>,
-    maxRetries = 3
-  ): Promise<T> {
-    for (let attempt = 0; attempt <= maxRetries; attempt++) {
-      try {
-        return await operation();
-      } catch (error) {
-        if (attempt === maxRetries) throw error;
-
-        const backoffMs = Math.min(1000 * Math.pow(2, attempt), 10000);
-        await new Promise(resolve => setTimeout(resolve, backoffMs));
-      }
-    }
-  }
-}
-```
-
-## 性能优化策略
-
-### 1. 签名缓存机制
-- 相同参数的签名结果缓存 5 分钟
-- LRU 策略，最大缓存 1000 条记录
-- 缓存命中率目标 >80%
-
-### 2. 并发控制
-- 使用 Promise 池控制并发签名请求
-- 最大并发数：50 (基于 100 QPS 需求)
-- 队列长度限制：200
-
-### 3. 内存管理
-- 敏感数据及时清理 (setTimeout 0)
-- 使用 WeakMap 自动回收凭据引用
-- 定期触发 V8 垃圾回收
-
-## 安全加固措施
-
-### 1. 输入验证
-- 所有签名请求参数严格类型检查
-- 平台类型白名单验证
-- 请求大小限制 (最大 1MB)
-
-### 2. 日志脱敏
-- 私钥信息完全屏蔽
-- API Key 仅记录前4位和后4位
-- 签名结果记录哈希摘要而非原文
-
-### 3. 内存保护
-- 使用 Buffer.allocUnsafe() 避免内存泄露
-- 敏感 Buffer 使用后立即 fill(0)
-- 避免字符串拼接造成的内存残留
-
-## 测试策略
-
-### 1. 单元测试
-- 每个签名适配器独立测试套件
-- Mock 外部依赖，隔离测试环境
-- 覆盖率要求 >90%
-
-### 2. 集成测试
-- 使用测试网络验证签名正确性
-- 配置热重载端到端测试
-- 权限控制场景覆盖
-
-### 3. 性能测试
-- 签名吞吐量基准测试 (目标 100 QPS)
-- 内存泄露检测 (长时间运行)
-- 并发压力测试
-
-## 部署和运维
-
-### 1. 监控指标
-- 签名请求 QPS 和延迟分位数
-- 错误率和重试率统计
-- 内存使用和GC频率
-
-### 2. 告警策略
-- 签名失败率 >5% 立即告警
-- 响应时间 p99 >200ms 告警
-- 配置重载失败告警
-
-### 3. 灾备方案
-- 配置文件多副本备份
-- 服务无状态设计，支持水平扩展
-- 降级策略：临时禁用非关键平台
-
-## 技术债务和风险
-
-### 1. 已知限制
-- 单进程设计，无法利用多核优势
-- 内存存储凭据，重启会丢失缓存
-- 配置文件格式变更需要重启
-
-### 2. 风险缓解
-- 定期安全审计和依赖更新
-- 监控和告警覆盖关键路径
-- 详细的操作手册和应急预案
-
-### 3. 后续优化
-- 考虑 Worker Threads 提升并发性能
-- Redis 集成支持分布式缓存
-- 配置中心集成实现动态配置

-## 用户场景与测试（必填）
-
-### 核心用户故事
-交易系统开发者和运维人员需要一个统一的账户凭据管理服务，能够从外部配置文件读取并管理多个加密货币交易所（Pacifica、Aster、Binance等）的私钥和API凭据，提供标准化的签名服务和账户信息注入功能，使得上层交易应用能够无缝接入不同平台而无需关心底层凭据管理的复杂性。
-
-### 验收场景
-1. **给定** 需要添加Pacifica账户凭据，**当** 提供Ed25519私钥、账户ID和子账户信息时，**则** 系统能够安全存储并支持Solana基础的签名操作。
-
-2. **给定** 需要添加Binance账户凭据，**当** 提供API Key、Secret Key和权限配置时，**则** 系统能够存储并支持REST API的HMAC-SHA256签名认证。
-
-3. **给定** 需要添加Aster账户凭据，**当** 提供以太坊私钥、用户地址和签名者配置时，**则** 系统能够存储并支持EIP-191签名方案。
-
-4. **给定** 需要添加OKX账户凭据，**当** 提供API Key、Secret、Passphrase时，**则** 系统能够存储并支持其特有的签名算法。
-
-5. **给定** 交易模块请求特定平台签名服务，**当** 提供平台类型、账户标识和待签名数据时，**则** 系统能够自动选择对应的签名算法和凭据进行处理。
-
-6. **给定** 应用需要获取账户配置，**当** 指定平台和账户标识时，**则** 系统能够返回该平台特定格式的完整账户信息（地址格式、API端点、权限范围等）。
-
-7. **给定** 系统需要支持新的交易所，**当** 定义新的凭据类型和签名方案时，**则** 系统能够通过插件化方式扩展支持。

+### 5. HedgingAccountPool（对冲账户池）
+
+**描述**：支持多平台对冲业务的账户池管理，提供负载均衡和故障转移。
+
+**属性**：
+```typescript
+interface HedgingAccountPool {
+  poolId: string;                       // 账户池ID
+  name: string;                         // 池名称

+interface HedgingAccountGroup {
+  primary: string[];                    // 主要账户ID列表
+  backup: string[];                     // 备用账户ID列表

+}
+
+enum PoolStatus {
+  ACTIVE = 'active',                    // 活跃
+  DEGRADED = 'degraded',                // 降级（部分账户不可用）
+  INACTIVE = 'inactive'                 // 不可用
+}
+```
+
+**验证规则**：
+- poolId在所有账户池中必须唯一
+- primary账户列表不能为空
+- 所有账户ID必须在系统中存在
+- 不同组别可以有重叠账户（支持备用降级）
+
+---
+
+### 6. AccountStatus（账户状态）
+
+**描述**：扩展账户状态信息，支持对冲业务实时监控。
+
+**属性**：
+```typescript
+interface AccountStatus {
+  accountId: string;                    // 账户ID
+  platform: Platform;                  // 所属平台

+  };
+}
+
+enum AccountHealth {
+  HEALTHY = 'healthy',                  // 健康
+  WARNING = 'warning',                  // 警告（性能下降）
+  CRITICAL = 'critical',                // 严重（频繁失败）
+  OFFLINE = 'offline'                   // 离线
+}
+
+interface PerformanceMetrics {
+  avgSignTime: number;                  // 平均签名时间(ms)
+  successRate: number;                  // 成功率 (0-1)
+  requestCount: number;                 // 请求次数
+  lastResetAt: Date;                    // 指标重置时间
+}

+  positions: Record<string, number>;    // 持仓 {symbol: amount}
+  lastUpdated: Date;                    // 更新时间
+}
+```
+
+**状态转换规则**：
+- HEALTHY → WARNING: 成功率降至95%以下
+- WARNING → CRITICAL: 成功率降至90%以下或连续失败>5次
+- CRITICAL → OFFLINE: 连续失败>10次
+- 任何状态 → HEALTHY: 成功操作且指标恢复正常
+

+
+### 7. AccountRegistry（账户注册表）
+
+**描述**：基于现有AccountRegistry模式的简化实现，避免复杂工厂适配器。
+
+**属性**：
+```typescript
+interface AccountRegistry {
+  // 基础账户管理
+  register(account: RegisteredAccount): void;
+  unregister(platform: string, accountId: string): boolean;
+  getCredentials(platform: string, accountId: string): Credentials | null;
+  hasAccount(platform: string, accountId: string): boolean;
+  listAccounts(): Array<{platform: string; accountId: string; metadata?: any}>;
+
+  // 对冲业务扩展
+  getAccountsByPool(poolId: string): RegisteredAccount[];
+  getHealthyAccounts(platform?: Platform): RegisteredAccount[];
+  selectAccountForTrading(poolId: string, strategy?: LoadBalanceStrategy): RegisteredAccount | null;
+  updateAccountStatus(accountId: string, status: AccountStatus): void;
+
+  // 热加载支持
+  reloadFromConfig(configPath: string): Promise<LoadResult>;
+  watchConfig(configPath: string): void;
+  stopWatching(): void;
+}
+
+interface RegisteredAccount {
+  platform: string;
+  accountId: string;
+  credentials: Credentials;
+  metadata?: {
+    name?: string;
+    description?: string;
+    pools?: string[];                   // 所属账户池
+    priority?: number;                  // 优先级
+  };
+}
+```
+
+**设计原则**：
+- 遵循宪章v1.6.0简化要求，避免过度抽象
+- 调用链控制在3层以内：业务层 → AccountRegistry → 存储层
+- 直接依赖注入，不使用复杂工厂模式
+- 内存缓存优化，O(1)查找性能

+
+    // 更新账户状态
+    await credentialService.updateAccountAfterTrade(selectedAccount.accountId, tradeResult);
+  }

+
+// 2. 事件驱动的状态同步

-**结构决策**：采用方案1单体项目结构，在现有src/目录下新增core/credential-manager/模块，与现有adapters/、types/、utils/等目录协同工作。选择此结构因为：1）与现有代码库架构一致；2）便于与其他交易模块集成；3）符合模块化设计原则。
+**结构决策**：采用单体项目结构，基于现有src/core模块扩展。使用模块化分层架构，遵循AccountRegistry简化模式，避免复杂的工厂适配器组合。credential-manager作为独立模块与现有http-client模块并行，通过类型定义保持松耦合。

 ## Notes
-- [P] tasks = different files, no dependencies between them
-- Verify contract tests fail before implementing interfaces
-- 集成优先架构: direct implementation in existing codebase structure
-- Performance targets: hot reload <100ms, signing <50ms
-- Integration-first: direct implementation in existing codebase structure
-- All file paths use absolute paths from repository root
+- [P] tasks target different files with no dependencies - safe for parallel execution
+- All contract tests MUST fail initially to ensure TDD compliance
+- AccountRegistry simplification pattern enforced per constitution v1.6.0
+- Performance targets: hot-reload <100ms, signing <50ms, 100+ concurrent accounts
+- Hedging focus: account pools, load balancing, Delta-neutral strategy support
+- Module interaction: event bus and service interfaces for trading system integration
+- All file paths specify exact locations in src/core/credential-manager/ structure
 
 ## Task Generation Rules Applied
+*Applied during main() execution*
 
 1. **From Contracts**:
-   - credential-manager.ts → contract test task T005 [P]
-   - pacifica-signer.ts → contract test task T006 [P]
-   - Additional signers → contract test tasks T007-T008 [P]
-   - ConfigLoader → contract test task T009 [P]
-
-2. **From Data Model**:
-   - Platform entity → enum definition task T013 [P]
-   - Account entity → interface definition task T015 [P]
-   - Credentials → type definition task T014 [P]
-   - Signer → interface definition task T016 [P]
-   - ConfigLoader → interface definition task T017 [P]
-
-3. **From User Stories** (quickstart.md):
-   - Hot reload scenario → integration test T010 [P]
-   - Multi-platform signing → integration test T011 [P]
-   - Performance requirements → integration test T012 [P]
+   - credential-manager.ts → ICredentialManager contract test [P]
+   - pacifica-signer.ts → IPacificaSigner contract test [P]
+   - Signer strategies → unified contract test [P]
+   - AccountRegistry → dedicated contract test [P]
+   - HedgingAccountPool → dedicated contract test [P]
+
+2. **From Data Model (data-model.md)**:
+   - HedgingAccountPool entity → model creation task [P]
+   - AccountStatus entity → model creation task [P]
+   - AccountRegistry → simplified pattern implementation [P]
+   - TradingModuleIntegration → service interface task
+   - ModuleEventBus → communication interface task
+
+3. **From User Stories (quickstart.md)**:
+   - Multi-platform signing example → integration test [P]
+   - Hot-reload example → integration test [P]
+   - Hedging workflows → integration test [P]
+   - Performance test → performance test [P]
 
 4. **Ordering Applied**:
-   - Setup → Tests → Types → Implementation → Integration → Polish
-   - Dependencies respected (platform detection before signers, etc.)

+# Credential Manager - 多平台对冲账号管理模块
+
+A comprehensive multi-platform account management system for cryptocurrency trading with hedging capabilities.
+
+## ✨ Features
+
+- **🔐 Multi-Platform Signing**: Support for Pacifica (Ed25519), Aster (EIP-191), and Binance (HMAC-SHA256)
+- **⚡ High Performance**: <50ms signing, <100ms hot-reload
+- **🏊 Account Pool Management**: Load balancing, failover, health monitoring
+- **🔄 Hot Configuration Reload**: Zero-downtime configuration updates

+
+## 🚀 Quick Start
+
+### 1. Basic Usage
+
+```typescript
+import { CredentialManager } from '@/core/credential-manager/CredentialManager'
+import { Platform } from '@/types/credential'
+
+// Initialize credential manager
+const credentialManager = new CredentialManager()
+
+// Load configuration
+await credentialManager.loadConfiguration({
+  accounts: [
+    {
+      id: 'pacifica-main',
+      name: 'Pacifica Main Account',
+      platform: Platform.PACIFICA,
+      enabled: true,
+      credentials: {
+        type: 'ed25519',
+        privateKey: 'your-hex-private-key'
+      }

+}
+```
+
+### 2. Trading Integration
+
+```typescript
+import { TradingOperation } from '@/core/credential-manager/TradingIntegration'
+
+// Sign trading request
+const tradingRequest = {
+  operation: TradingOperation.PLACE_ORDER,
+  platform: Platform.PACIFICA,
+  parameters: {
+    symbol: 'SOL/USDC',
+    side: 'buy',
+    quantity: 100,
+    type: 'market'
+  }
+}
+
+const result = await credentialManager.signTradingRequest(tradingRequest)
+// Returns platform-specific signature format ready for API submission
+```
+
+### 3. Hedging Operations
+
+```typescript
+// Cross-platform hedging
+const platforms = [Platform.PACIFICA, Platform.ASTER, Platform.BINANCE]
+const distribution = await credentialManager.getHedgingAccountDistribution(
+  500000, // $500k total volume
+  platforms
+)
+
+// Execute delta-neutral strategy
+const hedgeTrades = [
+  { operation: TradingOperation.PLACE_ORDER, platform: Platform.PACIFICA, /* ... */ },
+  { operation: TradingOperation.PLACE_ORDER, platform: Platform.ASTER, /* ... */ },
+  { operation: TradingOperation.PLACE_ORDER, platform: Platform.BINANCE, /* ... */ }
+]
+
+const results = await credentialManager.signBatchTradingRequests(hedgeTrades)
+```

+}
+```
+
+## 🏥 Health Monitoring
+
+The credential manager automatically monitors account health:
+
+```typescript
+// Check account health
+const healthStatuses = await credentialManager.checkAccountHealth(['account-1', 'account-2'])
+
+healthStatuses.forEach((status, accountId) => {
+  console.log(`${accountId}: Health ${status.healthScore} (${status.consecutiveFailures} failures)`)
+})
+
+// Update account status after trading
+await credentialManager.updateAccountAfterTrade('account-1', {
+  success: true,
+  tradeId: 'trade-123',
+  executedPrice: 120.5,
+  timestamp: new Date()
+})
+```
+
+## 📡 Event System
+
+Subscribe to real-time events:
+
+```typescript
+// Subscribe to account events
+const unsubscribe = credentialManager.subscribeToAccountEvents((event) => {
+  console.log(`Account ${event.accountId} on ${event.platform}:`, event)
+})
+
+// Subscribe to signing events
+credentialManager.subscribeToSigningEvents((event) => {
+  if (event.success) {
+    console.log(`Signing success: ${event.duration}ms`)
+  } else {
+    console.log(`Signing failed: ${event.error}`)
+  }
+})
+```
+
+## 🔄 Hot Configuration Reload
+
+The credential manager supports hot-reloading configuration files:
+
+```typescript
+// Enable file watching
+await credentialManager.loadConfigurationFromFile('config/accounts.json', {
+  enableHotReload: true,
+  watchDebounceMs: 100
+})
+
+// Configuration changes are automatically applied within 100ms
+// Service remains available during updates
+```
+
+## 🎯 Account Reservation
+
+Reserve accounts for complex trading strategies:
+
+```typescript
+// Reserve accounts for 30 seconds
+const reservation = await credentialManager.reserveAccountsForTrading(
+  ['pacifica-main', 'aster-main'],
+  30000
+)
+
+if (reservation.success) {
+  // Execute complex trading strategy
+  // Reserved accounts won't be used by other operations
+
+  // Release when done
+  await credentialManager.releaseReservedAccounts(['pacifica-main', 'aster-main'])
+}
+```
+
+## ⚡ Performance
+
+- **Signing Speed**: <50ms (typically 2-20ms depending on platform)
+- **Hot-Reload**: <100ms configuration updates
+- **Concurrent Operations**: Supports 100+ concurrent accounts
+- **Memory Efficient**: Minimal memory footprint
+- **High Throughput**: Optimized for high-frequency trading

-// ============================================================================
-// Integration Hints for Implementation
-// ============================================================================
-
-/**
- * Implementation Notes:
- *
- * 1. ECDSA secp256k1 Algorithm:
- *    - Use ethers.js or noble-secp256k1 library
- *    - Generate recoverable signatures (v, r, s format)
- *    - Support both transaction and message signing
- *
- * 2. EIP-191 Message Signing:
- *    - Prefix: "\x19Ethereum Signed Message:\n{message_length}{message}"
- *    - Use Keccak256 for hashing
- *    - Return signature in 0x format
- *
- * 3. Transaction Serialization:
- *    - RLP encoding for raw transactions
- *    - Include chainId for EIP-155 protection
- *    - Handle legacy and EIP-1559 transaction types
- *
- * 4. Performance Requirements:
- *    - Individual signing: < 50ms
- *    - Batch operations: optimize for concurrent requests
- *    - Consider WebWorkers for CPU-intensive operations
- *
- * 5. Security Considerations:
- *    - Validate transaction parameters
- *    - Check gas limits and prices
- *    - Implement replay protection
- *    - Never log private keys
- *
- * 6. Aster Network Specifics:
- *    - Chain ID: 592 (mainnet), 81 (testnet)
- *    - Support for both EVM and WASM contracts
- *    - Gas mechanics similar to Ethereum
