 - Phase 3-4：按计划实施
 
 ## 总结
-为多平台交易账户（Pacifica、Aster、Binance）提供统一的HTTP API调用客户端。核心要求包括：
-- 高性能：<100ms响应时间，99.9%可用性，1000+并发请求
-- 集成现有凭证管理库进行平台特定认证
-- 智能重试逻辑：网络错误重试，认证错误立即失败
-- 完整日志记录：30天保留期，包含敏感数据
-- 分层超时：连接5s，读取30s，写入15s，支持HTTP代理
-- 集成架构：集成到现有代码库，支持多账户并发调用

+## Notes
 
-## Task Implementation Guidelines
-
-### Setup Tasks (T001-T004)
-- Integrate with existing project structure in src/
-- Ensure TypeScript configuration supports new directories
-- Use existing Jest configuration and testing infrastructure
-- Maintain compatibility with current build process
-
-### Contract Tests (T005-T010)
-- Import interface definitions from contracts/ documents
-- Write tests that MUST FAIL initially (no implementation exists)
-- Cover all public methods defined in http-client.contract.md and platform-adapter.contract.md
-- Test proxy configuration scenarios from quickstart.md
-- Use existing testing patterns from the codebase
-
-### Type Definitions (T015-T019)
-- Implement interfaces from contracts/ exactly as specified
-- Include all entities from data-model.md (6 core entities)
-- Support TypeScript strict mode compliance
-- Organize types logically across httpClient.ts, platformAdapter.ts, and common.ts files
-
-### Platform Adapters (T023-T025)
-- Implement IPlatformAdapter interface exactly
-- Integrate with libs/credential-manager for authentication
-- Support platform-specific authentication: Ed25519 (Pacifica), EIP-191 (Aster), HMAC-SHA256 (Binance)
-- Include platform-specific error mapping as defined in contracts
-- Use existing httpClient.ts as reference for HTTP implementation patterns
-
-### Integration Tests (T011-T014)
-- Validate all 4 quickstart.md scenarios work end-to-end
-- Test with real API endpoints (as specified in plan.md constitution check)
-- Include performance benchmarks (<100ms response time)
-- Verify extensive proxy switching scenarios from quickstart.md
-- Cover proxy pool, failover, and health checking functionality
-
-### Advanced Features (T026-T029)
-- Implement proxy pool management with round-robin, health checks, and failover
-- Support connection pooling for performance optimization
-- Provide comprehensive health monitoring across all platforms
-- Enable batch request processing with concurrency control
-
-## Validation Checklist
-*GATE: Checked before task completion*
-
-- [x] All contracts (2 files) have corresponding tests (T005-T010)
-- [x] All entities (6 core entities) have type definitions (T015-T019)
-- [x] All tests come before implementation (T005-T014 before T015+)
-- [x] Parallel tasks truly independent (different files)
-- [x] Each task specifies exact file path in src/ or tests/
+- **[P] tasks**: Different files, no dependencies, safe for parallel execution
+- **TDD Order**: All contract and integration tests (T005-T014) must fail before starting implementation
+- **Credential Integration**: Priority focus on integrating with existing `src/core/credential-manager/`
+- **Performance Targets**: <100ms response time, 99.9% availability, 1000+ concurrent requests
+- **Quality Gates**: ESLint compliance, TypeScript strict mode, no 'any' types
+- **Architecture**: Adapter pattern with credential-manager deep integration
+
+## Task Generation Rules Applied
+
+1. **From Contracts**:
+   - http-client.contract.md → T005-T007 (core client tests)
+   - platform-adapter.contract.md → T008-T010 (adapter tests)
+
+2. **From Data Model**:
+   - HttpClient entity → T019 (HttpClientCore)
+   - PlatformAccount entity → T022-T024 (platform adapters)
+   - HTTPRequest/Response entities → T015-T016 (type definitions)
+   - AuthenticationContext entity → T021 (AuthenticationManager)
+
+3. **From Quickstart Scenarios**:
+   - Multi-platform balance query → T011 (Pacifica integration test)
+   - Concurrent requests → T012 (multi-platform test)
+   - Authentication flow → T013 (credential integration test)
+   - Proxy configuration → T014 (proxy routing test)
+
+4. **From Research Decisions**:
+   - Adapter pattern → T020 (PlatformAdapterFactory)
+   - Performance optimization → T029 (PerformanceMonitor)
+   - Credential-manager integration → T021, T027 (AuthenticationManager)
+
+## Validation Checklist ✓
+
+- [x] All contracts have corresponding tests (T005-T010)
+- [x] All entities have model/implementation tasks (T015-T026)
+- [x] All tests come before implementation (Phase 3.2 → 3.3)
+- [x] Parallel tasks are truly independent (different files)
+- [x] Each task specifies exact file path
 - [x] No task modifies same file as another [P] task
-- [x] Integration architecture maintained throughout (not independent library)
-- [x] Platform extensibility requirements addressed (factory pattern)
-- [x] Performance targets verified (T037, <100ms response time)
-- [x] Integration with existing libs/credential-manager (T030)
-- [x] Comprehensive proxy functionality (proxy pools, failover, health checks)
-
-## Notes
-- [P] tasks = different files, no dependencies
-- Verify tests fail before implementing (TDD)
-- Commit after each task completion
-- Maintain integration with existing codebase (not independent library)
-- Focus on extensibility per research.md (dynamic platform registration)
-- All proxy features must support extensive configuration scenarios from quickstart.md
-- Performance tests must verify <100ms response time goal
-- Use existing httpClient.ts patterns and winston logging setup
-
-## Success Criteria
-Upon completion of all tasks:
-1. ✅ Integrated HTTP client functionality in src/utils/universalHttpClient.ts
-2. ✅ Support for 3 platforms (Pacifica, Aster, Binance) with platform adapters
-3. ✅ Easy platform extensibility via PlatformAdapterFactory
-4. ✅ All quickstart.md scenarios functional including extensive proxy configurations
-5. ✅ Performance targets met (<100ms, 1000+ concurrent)
-6. ✅ Comprehensive proxy support (pools, failover, health checks, rotation)
-7. ✅ Full integration with existing libs/credential-manager
-8. ✅ 90%+ test coverage with contract-first TDD methodology
+- [x] TDD approach maintained (tests fail before implementation)
+- [x] Credential-manager integration covered (T013, T021, T027)
+- [x] Performance requirements addressed (T031, T036, T037)
