docs: update repository guidelines and project structure details

- Introduced a clientOrderId system for better order identification.
- Updated order creation logic to ensure unique clientOrderIds.
- Improved order cancellation methods to maintain accurate current orders.
- Added tests for new clientOrderId functionality and level state tracking.
- Ensured that desired orders have an intent field set for clarity.
- Enhanced snapshot functionality to include level states for grid lines.

 # Repository Guidelines
 
-## Project Structure & Module Organization
-The Bun entry point (`index.ts`) lives at the repo root for quick CLI smoke checks. All production code is under `src/`:
+## Package Manager
 
-- `src/strategy/` gathers every live trading engine (`maker`, `offset-maker`, `trend`). Shared helpers for strategy wiring sit in `src/strategy/common/`.
-- `src/core/` keeps order coordination plus shared libs used by multiple strategies.
-- `src/exchanges/` exposes the adapters and REST/websocket clients.
-- `src/ui/` implements the Ink dashboards for each strategy (they remain independent dashboards).
-- `src/logging/` contains the trade log helper.
-- `src/utils/` and `src/config.ts` hold cross-cutting utilities and runtime config.
-- `docs/` stores reference material, while `tests/` contains Vitest suites.
+**必须使用 Bun** — 本项目使用 Bun 作为包管理器和运行时。所有命令都必须用 bun 执行，**不要使用 npm、yarn 或 npx**。
 
-## Build, Test, and Development Commands
-- `bun install` – install dependencies.
-- `bun run index.ts` – launch the CLI menu.
-- `bun x vitest run` – execute the full test suite; `bun x vitest --watch` for incremental runs.
+## Project Structure
 
-Strategy-specific scripts still execute through the CLI; there is no separate `legacy/` workspace.
+入口 `index.ts` 在仓库根目录，用于 CLI 启动。所有生产代码在 `src/` 下：
 
-## Coding Style & Naming Conventions
-Use modern TypeScript with ES modules, two-space indentation, and sorted imports (external → internal). Favor `camelCase` for variables/functions and `PascalCase` for classes/enums. Place new strategies under `src/strategy/`, shared utilities under `src/utils/` or `src/strategy/common/` when they only apply to strategies. Keep comments focused on non-obvious trading logic.

-## Testing Guidelines
-Vitest powers unit/integration tests. Co-locate new tests next to their subject using `<feature>.test.ts`. Strategies should have coverage for order lifecycle, risk guards, and websocket edge cases. Run `bun x vitest --watch` during development for fast feedback.
+辅助目录：
+- `tests/` — Vitest 测试套件（大部分测试在此，少量与逻辑共处于 `src/`）
+- `docs/` — 交易所 API 参考文档
+- `scripts/` — 一次性脚本（密钥派生等）
+- `skills/` — AI 助手技能配置
 
-## Commit & Pull Request Guidelines
-Follow lightweight Conventional Commits (e.g. `feat: add hedging status panel`). Scope each commit to a single module or strategy. PRs should include:
-- Summary of changes.
-- Validation notes (commands run, environments touched).
-- Relevant logs or screenshots for behavior changes.
-Link issues/tasks when available.
+## Commands
+
+```bash
+bun install                  # 安装依赖
+bun run dev                  # 启动 CLI 菜单（等同于 bun run index.ts）
+bun run test                 # 执行全部测试（bun x vitest run）
+bun x vitest --watch         # 增量测试
+bun x tsc --noEmit           # 类型检查（无 typecheck 脚本，直接用 tsc）
+bun run lint                 # oxlint 检查
+bun run lint:fix             # oxlint 自动修复
+```
+
+⚠️ **不要用 `bun test`** — 那是 Bun 内置 runner，不支持 `vi.resetModules()`、`vi.waitFor()` 等 Vitest API。必须用 `bun run test`。
+
+## Coding Style
+
+- 现代 TypeScript + ES modules，严格模式（`strict: true`）
+- 两空格缩进，imports 按 external → internal 排序
+- 变量/函数用 `camelCase`，类/枚举用 `PascalCase`
+- 新策略放 `src/strategy/`，策略共享工具放 `src/strategy/common/`
+- 跨领域工具放 `src/utils/`
+- 注释只写非显而易见的交易逻辑
+- JSX 用于 Ink UI 组件（`react-jsx`）
+
+## Testing
+
+Vitest 驱动所有测试。测试文件两种位置：
+- `tests/<feature>.test.ts` — 大部分测试
+- `src/<module>/<feature>.test.ts` — 纯逻辑单元测试（如 `maker-points-logic.test.ts`、`swing-logic.test.ts`）
+
+策略测试应覆盖：订单生命周期、风控守卫、WebSocket 边界情况、状态恢复。
+
+## Commit Guidelines
+
+Conventional Commits（`feat:` / `fix:` / `refactor:` / `test:`），每次提交作用域限单个模块或策略。
 
 ## Environment & Secrets
-Duplicate `.env.example` to `.env` and populate API keys (Aster/GRVT) before running strategies. Do not commit secrets—use local `.env` or deployment secret managers. Rotate keys if they leak into logs or backups.
+
+复制 `.env.example` 为 `.env` 填入 API 密钥。**不要读取、打印或提交 `.env` 和任何密钥。** 泄露立即轮换。
+
+## Safety
+
+- 永远不要读取、运行、打印或访问 `.env` 或任何 secrets
+- 代码中遇到项目依赖时，先查版本再查文档，避免过时知识导致错误
