经三轮代码审计后的综合质量加固版本，覆盖协议核心层、数据正确性、 错误处理、测试真实度与可维护性。761 单测全绿（+58），ruff/mypy 全过。 主要修复： - 离线 .day 写入原子化（fsync + _repair_tail + 读取校验，CQS 守住） - 回测止损前视偏差（延迟下一根开盘 + 跳空保护） - VWAP 权重索引 / bar_time fail-fast / 绩效除零保护 - 闭包绑定 / 路径穿越 / naive datetime 跨时区 / ruff UP038 重构： - 抽 AsyncHeartbeatMixin 收敛 4 处心跳副本（12→1） - 统一 _RETRY_DELAYS 退避序列 / scanner 失败可观测性 新增 5 个测试文件 + 公共 API 类型契约，CI 加 Windows 矩阵 + trusted publishing 签名 + 锁文件。 详见 CHANGELOG.md
