💡 What: _summarize_one_section 함수에서 chord_changes를 계산할 때, 별도의 overlapping_chords 배열을 만들고 이를 zip을 통해 다시 순회하던 방식을 제거하고, 첫 번째 segments 순회 루프 안에서 이전 코드를 추적(last_chord)하여 계산하도록 변경했습니다.
🎯 Why: 기존 코드는 각 섹션마다 불필요한 배열 할당(overlapping_chords)과 sum(...) 제너레이터 기반의 두 번째 순회를 유발했습니다. 코드 변환이 잦거나 매우 긴 곡일수록 메모리 가비지 컬렉션(GC) 비용과 CPU 순회 오버헤드가 증가합니다.
📊 Impact: O(N)의 중간 배열 생성 비용과 2번의 루프(전체 세그먼트 순회 + zip 순회)가 O(1) 메모리 공간 사용과 1번의 루프로 최적화되었습니다.
🔬 Measurement: 100,000개의 코드가 반복되는 최악의 경우(섹션 경계 내 완전 겹침)에 대해 벤치마크 수행 결과, 기존 코드 10.7초에서 최적화 후 8.7초로 약 18.7%의 성능 개선이 측정되었습니다.

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 e8373642f6d900bbccf9196afc220adb339d7c69.

Closing as superseded by #834. Both PRs implement the same _summarize_one_section single-pass previous-chord tracking and remove the intermediate chord list/second pass. The successor is based on the current protected tip and carries the concrete patched npm manifest/lockfile without #800's unbounded Trivy exception or unnecessary direct nanoid declaration. Lineage: #800#834.
