Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 从 research_results 抽出纯回测核心能力，形成独立成员仓。 ## 模块（10 个核心） | 模块 | 内容 | |---|---| | alpha_factors | 158 alpha 公式 + 24 基础算子（移植自 qlib alpha158）+ JSONB 工具 | | execution | 执行仿真（成本/滑点/T+1/涨跌停/部分成交/价差）+ 多日 NAV + PnL 拆解 | | indicators | 50+ 技术指标（MACD/KDJ/布林/ATR/ADX/等） | | data_adapter | 桥接 qtdb_pro 长表与新模块（rename/long-wide/复权/vwap 代理） | | backtest | weight-based 多日仿真 | | metrics / perf_stats | 绩效指标 | | factor_library | 通用方法（turnover/IC/winsorize/OLS） | | portfolio_decomp / risk | 组合分解 + 风险指标 | | logging | 统一 logger（标准库 + 可选 loguru） | ## 设计原则 - 零重型依赖（numpy/pandas/scipy） - mypy strict 0 errors（12 source files） - 394 tests passed（从 research_results 复制 + 适配） - ruff clean ## 与 research_results 的关系 - research_results 通过 re-export wrapper 保持向后兼容（src.shared.X → quant_engine.X） - 47 proj 的 import 路径暂时不变，后续逐步迁移 - 本仓角色：researchhub_workspace 引擎层 Co-Authored-By: Mavis --- .gitignore | 14 + README.md | 86 + pyproject.toml | 66 +
