 ## 2026-08-09 - [대용량 로그 스캔 시 정규표현식 실행 전 O(N) 서브스트링 검증 선행]
 **Learning:** `classify_testthat_failure`에서 테스트 실패 내역이 없는 2MB 로그 파일을 대상으로 정규표현식을 실행하면 약 20ms가 소요되지만, 단순 문자열 검색은 약 1ms만 소요됩니다. 문자열 존재 여부가 정규표현식 매칭의 전제 조건일 때, 콜드 패스(Cold Path)에서 순서 최적화는 매우 큰 성능 차이를 만듭니다.
 **Action:** 대용량 텍스트 입력(CI 로그 등)에서 복잡한 정규표현식을 파싱하기 전에 항상 빠른 O(N) 문자열 존재 여부 확인을 먼저 수행하십시오.
+## 2026-08-19 - Python에서 정규식 검색(Regex Search)을 통한 스캔 최적화
+**Learning:** `scripts/ci/redact_sensitive_log.py`에서 민감한 데이터를 마스킹할 때 문자열을 문자 단위로 반복(`cursor += 1`)하며 검사하는 방식은 큰 문자열에 대해 파이썬에서 O(N)의 오버헤드를 발생시키는 성능 병목 지점이었습니다. 추가적으로, 단순 문자열 매칭 시 숫자나 기호를 포함하여 우회하려는 시크릿(예: t0k3n)도 함께 탐지하기 위해 난독화 패턴 확장이 필요합니다.
+**Action:** 대용량 문자열을 스캔할 때는 수동으로 문자를 하나씩 전진(`cursor += 1`)시키는 대신, 미리 컴파일된 정규식의 `.search(text, cursor)`를 사용하여 C 속도로 다음 매치 지점까지 효율적으로 건너뛰고 매치 주변의 문맥(키나 따옴표 등)을 파악하기 위해 역추적(backtrack)하는 방식을 사용해야 합니다.
