ZCLAW 架构优化 - Phase 2: 领域重组 实施计划

For agentic workers: REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 按领域重组代码结构，迁移到 Valtio 状态管理，引入 XState 状态机

Architecture: 创建 domains/ 目录，按业务领域组织代码，使用 Valtio 替代 Zustand，使用 XState 管理 Hands 状态

Tech Stack: TypeScript, Valtio, XState, React

Spec Reference: docs/superpowers/specs/2026-03-21-architecture-optimization-design.md

Duration: 4 周 (16 人日)

export { useHandsState, useHands, useApprovalQueue, useHandsActions } from './hooks';

• Step 4: 提交 Hands Domain

cd g:/ZClaw_zclaw && git add desktop/src/domains/hands/
git commit -m "$(cat <<'EOF'
refactor(hands): complete hands domain migration

- Add Valtio store for hands state
- Add React hooks for hands access
- Export all from domain index

Chunk 4: Shared Module 提取

Task 4.1: 创建共享错误处理

Files:

• Create: desktop/src/shared/error-handling.ts

• Create: desktop/src/shared/types.ts

• Create: desktop/src/shared/index.ts

• Step 1: 创建错误处理工具

Create desktop/src/shared/error-handling.ts:

/**
 * Shared Error Handling
 *
 * Unified error handling utilities.
 */

export class AppError extends Error {
  constructor(
    message: string,
    public code: string,
    public cause?: Error
  ) {
    super(message);
    this.name = 'AppError';
  }
}

export function isError(error: unknown): error is Error {
  return error instanceof Error;
}

export function getErrorMessage(error: unknown): string {
  if (isError(error)) {
    return error.message;
  }
  return String(error);
}

export function wrapError(error: unknown, code: string): AppError {
  if (error instanceof AppError) {
    return error;
  }
  return new AppError(getErrorMessage(error), code, isError(error) ? error : undefined);
}

• Step 2: 创建共享类型

Create desktop/src/shared/types.ts:

/**
 * Shared Types
 */

export type Result<T, E = Error> =
  | { ok: true; value: T }
  | { ok: false; error: E };

export type AsyncResult<T, E = Error> = Promise<Result<T, E>>;

export interface PaginatedResponse<T> {
  items: T[];
  total: number;
  page: number;
  pageSize: number;
}

• Step 3: 创建 Index

Create desktop/src/shared/index.ts:

/**
 * Shared Module
 */
export * from './error-handling';
export * from './types';

• Step 4: 提交共享模块

cd g:/ZClaw_zclaw && git add desktop/src/shared/
git commit -m "$(cat <<'EOF'
refactor(shared): create shared module

- Add AppError class for unified error handling
- Add Result type for functional error handling
- Add PaginatedResponse type

Chunk 5: 集成和验证

Task 5.1: 创建向后兼容层

Files:

• Modify: desktop/src/store/chatStore.ts

• Step 1: 更新旧 Store 重导出

Update desktop/src/store/chatStore.ts to re-export from domain:

/**
 * Chat Store - Backward Compatibility Layer
 *
 * This file re-exports from the new domains/chat module.
 * Import from '@/domains/chat' for new code.
 */
export * from '../domains/chat';

• Step 2: 提交兼容层

cd g:/ZClaw_zclaw && git add desktop/src/store/chatStore.ts
git commit -m "$(cat <<'EOF'
refactor(chat): add backward compatibility layer

- Re-export from domains/chat for backward compatibility
- Maintains existing import paths

)"

---

Task 5.2: 运行测试验证

• Step 1: 运行 Chat Store 测试

Run:

cd g:/ZClaw_zclaw/desktop && pnpm test tests/store/chatStore.test.ts

Expected: Tests pass with new Valtio store

• Step 2: 运行所有测试

Run:

cd g:/ZClaw_zclaw/desktop && pnpm test

Expected: No new test failures

---

Task 5.3: 更新文档

• Step 1: 创建 Phase 2 变更日志

Create docs/changelogs/2026-03-21-phase2-domain-reorganization.md

---

Verification Checklist

Domain Structure

• domains/chat/ created with types, store, hooks
• domains/hands/ created with types, machine, store, hooks
• shared/ created with error-handling, types

State Management

• Valtio installed and configured
• Chat store migrated to Valtio
• Hands store migrated to Valtio
• XState machine created for hands

Compatibility

• Backward compatibility layer in place
• Existing imports still work
• Tests passing

---

Next Steps (Phase 3)

• Valtio 性能优化
• XState 状态机完整集成
• Intelligence 缓存增强
• 组件迁移到新 Hooks
