"""Anti-overfit robustness layers (doc 06 §4).

Read-only analyses **over** a finished result (the study, the trade list, the
equity curve). They never touch the engine or mutate results. Run them on
finalists *before* spending MT5 time. Treat them as report-only signals by
default; tighten into hard gates as you gain confidence.
