      <description>운용 컴퓨터를 바꾸는 날마다 아침 매매가 비었다. 수칙으로 막았다가 재발했고, 테스트를 통과한 수정은 저장을 한 번도 하지 않았다. 조건이 참일 때 동작하는지가 아니라, 그 조건이 참이 되는 순간이 실제로 오는지를 물어야 했다.</description>

      <description>코스닥 종목이 코스피 기준 손절선을 받던 결함을 고치고 테스트까지 붙였다. 그런데 두 시장의 값 자리를 서로 바꿔 넣어도 테스트는 전부 통과했다. 테스트를 늘리는 대신 틀릴 수 없는 모양으로 바꿨다.</description>

      <description>매수 판단을 맡긴 언어 모델을 바꿔 보기 전에, 바꾸지 않았을 때 얼마나 흔들리는지부터 쟀다. 15건으로는 2.4%였고, 전량으로 다시 재니 7.98%였다.</description>

      <description>매수 판단 단계를 빼는 게 낫다는 결과가 나왔다. 실제 운용의 제약 하나를 빠뜨리고 잰 값이었다. 그 제약을 넣자 빼는 안이 가장 나빴다.</description>

      <description>매매 기록을 짝지어 만든 표의 총합이 원장과 원 단위까지 일치했다. 그런데 결론의 부호가 반대였다. 검산해야 할 것은 합계가 아니라 건수와 분해였다.</description>

      <description>시세를 받아 캐시에 쌓는 루프가 장이 갈수록 무거워졌다. 한 바퀴가 33.4초에서 364.2초로 늘었고, 진짜 피해는 루프가 아니라 그 캐시를 읽는 쪽에 났다.</description>

      <description>판단을 한 번 더 검증하려고 둔 호출이었다. 88건을 전수로 뜯어보니 두 판단의 불일치가 0건이었고, 그 0건은 안전의 증거가 아니라 복제의 증거였다.</description>
