"""Validazione dei worker live multi-asset (TR01/ROT02/TSM01): il replay bar-by-bar del
worker riproduce la funzione di backtest di riferimento?

Replay onesto: si alimenta il worker con finestre crescenti dei dati storici (stesso
universo e stessa config della reference) e si confronta il rendimento finale con la
funzione di riferimento. Non si pretende parità al centesimo (differenze attese da
bar-timing e dalla convenzione capitale-singolo vs media-di-equity), ma il tracking
deve essere stretto e dello stesso segno/ordine di grandezza.

Riferimenti:
  TR01  -> honest_improve2._tr_basket_daily
  ROT02 -> honest_improve2._rot_daily_equity
  TSM01 -> tsmom_research.tsmom_sim

Run: uv run python scripts/analysis/validate_honest_workers.py
