"""VERDICT_CONSISTENCY_LOCK_V1
Verdict 일관성 잠금 — FINAL_JUDGMENT_GATE_V1 verdict를
operational_report.json의 종목별 서술과 대조한다.

위반(INVALID_VERDICT_OVERRIDE):
  - verdict=BLOCKED/WATCH/SELL 인데 보고서가 해당 종목에 BUY·신규매수·매수 서술
  - verdict=BUY_PILOT 인데 보고서가 해당 종목에 SELL·매도 서술 (과소평가 방지)

정직성 원칙:
  - 사용자 H10 수동 오버라이드(HTS 입력표에 명시)는 예외
  - sell_priority 표의 "보유"는 매도 미진행이므로 SELL verdict와 충돌 아님 (보수적 안전)
  - TRIM verdict와 "보유"는 충돌 — TRIM 지시가 무시된 것
