\section{Introduction}
\label{sec:introduction}
% TODO content notes:
% - Motivate why backtest correctness matters: a single off-by-one index in a
% vectorized backtester can silently fabricate alpha.
% - State the concrete finding up front: a 15-hyperparameter "golden kernel"
% (K12 / Iter12) produced via genetic-algorithm search showed Sharpe 14.49
% on BTCUSDT 1m data — and the same kernel, run honestly (bar-by-bar, no
% future information), collapses to Sharpe -0.25.
% - Frame the contribution: not just "we found a bug," but a reusable
% noise-harness methodology (Section 5) that any quant team can run against
% their own backtester to detect this class of defect using pure
% Geometric Brownian Motion data with zero real signal.
% - End with a roadmap of the paper (one sentence per remaining section).
