💡 What: surveyFA.R에서 p-value의 최솟값을 찾을 때 사용되던 sort() 기반 탐색을 which.min()으로 변경했습니다.
🎯 Why: 전체 데이터를 정렬하는 sort()는 O(N log N)의 시간 복잡도를 가지며 큰 데이터에서 불필요한 병목을 유발합니다. 이를 which.min()으로 대체하여 O(N) 선형 탐색으로 최적화했습니다.
📊 Impact: 데이터의 최솟값 탐색에 필요한 불필요한 메모리 복사와 정렬 오버헤드가 제거되어 빠른 실행이 가능합니다.
🔬 Measurement: 기존 테스트 코드들이 모두 통과되는 것을 확인합니다.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

  • Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

  • Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

  • Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

  • Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

  • Result: REQUEST_CHANGES

  • Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head 6034b703de6b5d99e795d85d949d8c2981f23223.

Live source-diff 재감사 결과, 이 PR의 sort()→which.min() 변경(또는 #141의 경우 남은 코드 변경 없음)은 활성 대체 PR #158 (current head 01b5eee)에 포괄되어 있습니다. #158은 동일 O(N) 선택을 유지하면서 길이 0 결과, NA/threshold, fallback 경계와 전용 회귀 테스트 및 리뷰 수정을 포함합니다. 단일 검증 경로를 유지하기 위해 #158로 superseded 처리하여 닫습니다.
