-- **`data/exchanges/rest.ts` 包含硬编码的 Binance API Key**（第 105-106 行），不要提交到公开仓库。
-- `env.yaml` 包含明文数据库密码且被 git 追踪，注意安全。
+- **所有 API Key 统一在 `env.yaml` 中管理**，禁止在代码中硬编码。新增交易所时在 `exchange` 段添加对应子配置即可。
+- `env.yaml` 包含明文密钥和数据库密码且被 git 追踪，注意安全，不要提交到公开仓库。
 - 未安装 Python 依赖（如 pydantic），`engine/` 目录有独立的 `.venv/`。
 - `db/pgsql/` 在 `.gitignore` 中，这是 TimescaleDB 数据目录（Docker volume 映射）。
 - `KLINE_INTERVAL_MS` 常量定义了两处：`data/exchanges/rest.ts` 和 `data/types/kline.ts` 的类型定义。新增周期需同步。
