"""Kalibrierung der Gesamtempfehlung (2026-07-24, Idee 2 „Verdict ans eigene
Erfolgsrezept halten"): Ist die angezeigte Konfidenz (conf_pct) PRÄDIKTIV — sagt
conf=80 mehr Erfolg voraus als conf=55? Und: sind die unbelegten Verdict-Stimmen
(KI-Copilot ai_sentiment, news_score) prädiktiv?

Methodik wie beim P(break)-Modell (dem kalibrierten Erfolgsfall):
  - `recommendations` (LONG/SHORT) aus der DB, Sampling ≥15 min Abstand
    (Autokorrelation dämpfen — die Empfehlung ändert sich minütlich kaum).
  - Forward-Return = Signalrichtung × (Close[t+H] − Close[t0]) / ATR(M5, t0)
    für Horizonte 1 h und 2 h (M5-Bars von MT5; rec.timestamp = lokale Epoch,
    Bar-Zeit = Broker-Zeit → −3 h).
  - Bins über conf_pct → n / WR(fwd>0) / Ø-fwdR je Bin, in ZWEI Zeitraum-Hälften
    (Sign-Stabilität wie immer).
  - Copilot: ai_sentiment (LONG/bullish=+1, SHORT/bearish=−1) → Ø-fwdR in
    Copilot-Richtung (unabhängig vom Wave-Signal!). News: Vorzeichen news_score.
Kalibriert = monoton steigende Ø-fwdR über die conf-Bins, in BEIDEN Hälften.
