🧹 [code health improvement description]

[seonghobae]

🎯 What: Moved content.splitlines() execution outside of the SCAN_RULES iteration loop in _scan_file.
💡 Why: content.splitlines() was being redundantly executed for every single rule in SCAN_RULES. Extracting it to a variable reduces unnecessary repeated overhead and improves code readability.
✅ Verification: Ran python3 scanner/cli/vibesec.py scan . manually to ensure the scanner logic functions and parses files successfully as before. Also ran python3 -m py_compile scanner/cli/vibesec.py.
✨ Result: Enhanced performance marginally per file scan, by avoiding re-computation of content.splitlines() on every loop iteration, leading to cleaner code.

📝 Walkthrough

Summary by CodeRabbit

릴리스 노트

• 최적화
  • 파일 스캔 성능을 개선했습니다. 라인 목록이 한 번만 생성되고 스캔 규칙들이 동일한 배열을 재사용하도록 변경되어 메모리 효율성이 향상되었습니다.

전체 요약

_scan_file 함수에서 라인 목록 생성 방식을 변경했습니다. content.splitlines()를 직접 열거하는 대신 미리 lines 변수에 저장한 후, 규칙 루프에서 동일한 배열을 기준으로 순회하도록 개선되었습니다. 이로 인해 라인 목록이 한 번만 생성되고 각 규칙에서 재사용됩니다.

변경 사항

라인 분해 최적화

레이어 / 파일	요약
라인 사전 생성 및 재사용 scanner/cli/vibesec.py	_scan_file 함수에서 lines = content.splitlines()로 라인 배열을 미리 생성하고, 규칙 필터링 루프에서 이 배열을 반복 사용하도록 리팩토링되었습니다.

예상 검토 난이도

🎯 1 (Trivial) | ⏱️ ~5분

축하 시

🐰 한 번의 분해로 충분하네,
라인 목록을 미리 만들고,
모든 규칙이 함께 나누네,
효율의 토끼 발걸음,
더 빠른 스캔의 시작이라!

Reviewed the diff — hoisting splitlines() out of the inner loop is a safe cleanup with unchanged scan behavior.
