Residual Edge Analyzer

Overview

Test whether a strategy's apparent performance survives explicit comparison with predeclared baseline return series. Produce an auditable JSON artifact and a concise Markdown report without fetching data or changing trading exposure.

Treat this as a falsification gate after backtest-expert, not as trade authorization.

Prerequisites

• Use Python 3.9+.
• Prepare one CSV containing an ISO date, strategy return, and every baseline return on the same row.
• Prepare a JSON specification following references/input-contract.md.
• Supply actual period returns. Do not substitute CAGR, Sharpe, cumulative P&L, or other summary metrics.
