"""
Match Report — calibrated outcome probabilities + loss-minimizing pick per match.
================================================================================
For each match, shows the model's CALIBRATED probability for every outcome
(1X2, Double Chance, OU 1.5/2.5/3.5, BTTS, HT), next to the market's implied
probability, and recommends:
  * EN GÜVENLİ  = highest-probability outcome (most likely to hit / lowest variance)
  * EN İYİ DEĞER = least-negative-EV outcome (smartest bet given the margin)

Probabilities are leak-free and calibrated (ECE ~0.43%, see calibration_report).
This is a LOSS-MINIMIZER, not a profit machine — accurate probabilities to make
the smartest, least-losing decisions against İddaa's high margin.

Trains the market models on the full history (leak-free), then scores the input.

Usage:
  python scripts/match_report.py --features data/upcoming_features.csv
  python scripts/match_report.py --demo --n 6
