"""스윙 5·6회차 — 결과 불명 매도·DT 물량 과다매도 방지 회귀 테스트 (2026-10-02).

모든 시나리오는 상태를 가진 KIS 시뮬레이터(보유/주문가능 수량이 주문에 따라 실제로 줄어듦)
위에서 **3주기 이상** 돌린다. 5회차 수정은 확인 대기를 1주기만 보호해 3주기째 DT 물량을 팔았다
(6회차 C-1 재현 ①②). 6회차 수정:
  (c) 국내 매도 직전 항상 KIS 실보유 확인, 상한 = min(주문가능, 보유) − DT 인메모리
  (a) 결과 불명 체결분을 KIS 보유 감소로 확인해 장부(TradeHistory·reflect_sell·ActiveTrade·
      loss_tracker) 반영 후 그 주기 skip
  (b) 결과 불명 직후 Portfolio sync 요청

규약(CLAUDE.md §4.1): 주문 목은 공통 종단(safe_place_order). 기대값은 settings.*.
