"""Validazione DURA del solo edge sopravvissuto alla ricerca shape: ML walk-forward
(LogisticRegression) sulle feature di FORMA. Tutto il resto della famiglia shape e' rumore.

Candidato: BTC logit W24H12 th0.58 (FULL +219% / OOS +42% / Sharpe 2.72 / 8-9 anni+,
regge fee 0.20% RT). Prima di promuoverlo a strategia serve (metodologia obbligatoria):
  1. ROBUSTEZZA MULTI-ASSET: stessa config su BTC/ETH/LTC/SOL/ADA/XRP 1h.
  2. WALK-FORWARD ROLLING (train fisso 2y) oltre all'expanding -> niente "memoria infinita".
  3. STRESS leva 2x + slippage doppio (fee 0.20% RT) -> regge in condizioni realistiche?
  4. ROBUSTEZZA SU GRIGLIA (th, W, H) -> plateau, non picco.
  5. CORRELAZIONE col MASTER + integrazione -> e' un diversificatore (free-lunch)?

Tutto netto-fee, OOS = ultimo 30%. Conta il PnL netto, non l'accuracy (lezione squeeze).

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