"""TEST DECISIVO: impatto di EXIT-16 (close_confirm_sl, buffer=0.5 ATR) sul PORT06,
nel PATH CANONICO del backtest (NON exit_lab).

EXIT-16: lo SL intrabar e' DISATTIVATO; si esce al close del bar j solo se il close
ha sfondato il livello di buffer*ATR14:
  long  (d=1):  esci a close[j] se close[j] < sl0 - 0.5*atr14[j]
  short (d=-1): esci a close[j] se close[j] > sl0 + 0.5*atr14[j]
TP intrabar al livello e max_bars al close restano INVARIATI.

Metodo (come fu fatto per il loss-guard Hurst):
  1. build_everything() canonico -> equity giornaliere di TUTTI gli sleeve (cache intatta).
  2. ricostruisco le 6 equity fade in variante EXIT-16 replicando ESATTAMENTE
     fade_daily_equity/build_trades (stessi segnali fn(df,**params), trend_max=3.0,
     fee 0.10%RT*lev3, pos 0.15, compounding, non-overlap), cambiando SOLO il ramo SL.
  3. PARITA': con la SL-rule originale il replay deve riprodurre le equity canoniche.
  4. PORT06 base vs EXIT-16 con la STESSA matematica dei pesi (Portfolio.backtest):
     weighting cap, caps PAIRS 0.33, ribilancio 1D, metriche FULL e OOS.

NB: la leva 2x del portfolios.yml NON entra nel backtest (Portfolio.backtest la ignora;
e' un knob live). Le equity fade gia' includono lev=3 dentro build_trades.
