"""HORIZON_CLASSIFICATION_V1 — 종목별 투자 기간 분류기.

data_feed 및 fundamental_multifactor_v3 결과를 결합하여
각 보유 종목의 투자 기간(단/중/장기)을 결정론적으로 분류한다.

분류 결정 트리:
  LONG  ← 핵심 주도주(005930/000660) + 펀더멘털 B등급
  MID   ← 그 외의 펀더멘털 C/D등급 또는 중립 구간
  SHORT ← 과열/약세가 동시에 강한 종목(고RSI, 강한 음의 이격도, 고ATR)
  ETF   ← ETF 종목
  UNKNOWN ← 데이터 부족

출력: Temp/horizon_classification_v1.json
