Backtesting against a hostile substrate

the crypto test checklist

The module's defences as one pass: regime-split results, funding charged (leveraged rules), fills honest on real books, the sample counted as regimes not trades, the venue and custody clauses executed, and a mechanism that should hold across regimes - all against a substrate built to manufacture false confidence. Where equity tests failed by constructing kind worlds, crypto tests fail by believing a history that is three experiments.
