DeepSeek Harness Plugin: dsh-quant-factor-pipeline (Quantitative Factor Research Pipeline)

The `dsh-quant-factor-pipeline` plugin for DeepSeek Harness (DSH) is designed to encapsulate the end-to-end quant factor research process into an orchestratable workflow tool. It provides complete functionality, from panel data retrieval, factor calculation (with IC gating), and coarse-grained Regime detection, through backtesting, to project state persistence. Installation requires manually running the relevant npm command, and the plugin runs on Node 22.22.2 with zero dependencies. It uses environment variables to specify data directories and log paths, and strictly separates valid data endpoints from restricted ones to ensure compliant data fetching. The author advises version locking and clarifying the responsibility boundary with `dsh-quant-data-mcp`.
