💡 무엇을
app.jscomputeTaskMetrics 함수 내부에서 사용되던 Array.prototype.reduce, Array.prototype.forEachMap 객체를 표준 for 루프와 Float64Array 형식화 배열(Typed Array)로 교체했습니다.

🎯 왜
기존 방식은 작업 목록을 순회할 때마다 고차 함수(higher-order function)의 콜백 할당, 가비지 컬렉션(GC) 부하, 그리고 Map 객체를 통한 해시 룩업 비용이 발생하여 렌더링 성능에 병목을 유발했습니다. 작업(task)의 개수가 많아질수록 이 오버헤드는 선형적으로 증가합니다. 이를 연속된 메모리 공간을 사용하는 Float64Array와 콜백 없는 표준 for 루프로 전환하여 자바스크립트 엔진의 배열 순회 및 데이터 접근 속도를 극대화하기 위함입니다.

📊 예상 효과

  • reduce, forEach 콜백 생성 및 실행에 따른 메모리 할당과 가비지 컬렉션(GC) 압박 제거
  • Map.setMap.get 호출 시 발생하는 해시 룩업(hash-lookup) 비용을 O(1)의 배열 인덱스 접근으로 단축시켜 작업 메트릭 계산 시 CPU 오버헤드 대폭 감소

🔬 검증 방법

  • npm run test:api && npm run test:unit && npm run test:e2e 전체 테스트 스위트를 실행하여 회귀 문제나 부작용이 없음을 확인했습니다. (기존 실패 케이스 1건 제외)

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

📝 Walkthrough

Walkthrough

computeTaskMetricsMap, reduce, forEach 대신 Float64Array와 표준 for 루프를 사용하도록 변경되었습니다. 동일한 계산 결과와 반환 객체를 유지합니다. 관련 성능 지침도 추가되었습니다.

Changes

반복 처리 성능 개선

Layer / File(s) Summary
작업 지표 계산 최적화
.jules/bolt.md, app.js
computeTaskMetrics가 작업 위치를 기준으로 Float64Array에 기간을 저장합니다. totalDays와 후속 기간 계산은 표준 for 루프로 처리합니다. 배열 고차 함수와 Map 사용 지침을 추가했습니다.
