👋 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 New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

📝 Info: Int32Array cache stays equivalent to old Map
calculateDurationDays only returns integers, so Int32Array storage causes no truncation. Both loops walk state.tasks in the same order and length, so index i aligns with the old task.id keying. durations[i] is always a number, leaving the durationDays !== undefined branch in calculatePlannedProgressRatio unchanged.

Closing as a proven duplicate of the existing canonical performance lane #508; there is no unique production behavior or acceptance evidence here to preserve. Fresh exact state is unchanged at #508 is strictly stronger as the owning lane because it also carries a deterministic 10,000-task Chromium benchmark, exact semantic-fingerprint equality before accepting the timing result, immutable event-bound comparison-SHA selection, a 15% median improvement gate with bounded CI retries, fail-closed benchmark-base resolution, canonical unit/E2E registration, and review-driven regression coverage for missing/invalid comparison authority. This two-file PR adds none of those acceptance controls. The local Node timing quoted here is therefore supplementary at best, and the statement that an E2E failure is 'pre-existing' is not acceptable merge evidence under the current quality contract. The one current Devin thread only confirms semantic equivalence of the Int32Array/indexed-loop implementation; it does not identify unique work. Preserve #508 as the single implementation/evidence owner and re-evidence its then-current exact head under the repaired exact-head CI/security controls before integration. |
Understood. Acknowledging that this work is now obsolete and stopping work on this task. I will not proceed with PR submission as #508 is the canonical implementation. |

💡 무엇을
app.js의computeTaskMetrics함수에서 사용하는 배열 반복 메서드(reduce,forEach)를 일반for루프로 변경했습니다.Map객체를Int32Array로 대체했습니다.🎯 왜
computeTaskMetrics는 렌더링, CSV 내보내기, 상태 저장 등 여러 핵심 작업에서 수시로 호출되는 중요한 계산 함수입니다.reduce와forEach는 반복할 때마다 콜백 함수를 할당하고 호출하는 오버헤드를 유발하며,Map은 추가적인 힙 메모리 할당 및 해시 룩업 비용을 발생시킵니다.📊 영향
🔬 측정
test_perf.cjs를 통해 10,000개 작업을 100회 반복한 벤치마크 결과 비교:npm run test:unit및npm run test:e2e를 통해 기능 변경 없이 정확성이 유지되는지 확인했습니다. (e2e 테스트 중 발생하는renders seeded rows and summary metrics오류는 기존부터 존재하는 문제임을 확인했습니다)PR created automatically by Jules for task 7956313223111682527 started by @seonghobae
