"""GATE PORT06: trend_max=3.0/ema_long=200 sulle 6 fade LIVE (improvement-sweep punto 7).

Contesto. Il backtest canonico (build_everything) applica il filtro trend alle fade,
ma in produzione le SleeveSpec di _defs.py NON lo passano -> le fade live fadano anche
i trend/crolli estesi (es. MR01/MR02_ETH long ripetuti nel crash ETH del 2026-06-05).
Anche il test PORT06 del loss-guard Hurst (fade_lossguard_port_test) fu misurato su
entries GIA' trend-filtrate -> la config live attuale (hurst SENZA trend) non e' mai
stata gateata. hurst e trend si sovrappongono (entrambi tagliano il regime trending):
il delta marginale va misurato sul path live, non assunto dai numeri canonici.

Confronto, a livello PORT06 (stessa matematica pesi cap di Portfolio.backtest):
  LIVE      = fade con hurst_max=0.55 + EXIT-16 (sl_confirm 0.5 ATR), trend OFF  [prod oggi]
  CANDIDATO = LIVE + trend_max=3.0 / ema_long=200                                 [proposta]
  TREND-ONLY= EXIT-16 + trend, senza hurst                                         [diagnostica overlap]

Parita' preliminare: il replay (mode=orig, trend ON, no hurst, no EXIT-16) deve
riprodurre le equity fade canoniche (come exit16_port06_impact).

La maschera Hurst e' quella ESATTA del live: fade_base.hurst_skip_mask (close-only,
window=100, step=6) — non la cache di regime_lab.

GATE (sweep): PROMOSSO se OOS Sharpe non peggiora (>= base-0.02) E il DD scende,
e in FULL non degrada.
