💡 What: transcript_search.py에서 검색어 필터링 시 초기 집합(candidates) 할당 과정에서 불필요하게 set(postings)로 방어적 복사본을 생성하던 코드를 원본 참조(postings)를 직접 사용하도록 수정했습니다.
🎯 Why: 교집합 연산자(&)는 본질적으로 새로운 집합을 반환하므로, 초기 O(N)의 set() 복사는 불필요한 메모리 할당과 성능 저하를 초래하는 병목 지점이기 때문입니다.
📊 Impact: 검색 시 첫 번째 단어에 대한 O(N) 집합 복사 연산을 제거하여 검색 실행 시간과 메모리 사용량을 절감합니다.
🔬 Measurement: tests/test_transcript_search.py 및 전체 테스트 스위트가 정상 통과하는 것을 확인하여 기능 변경 없이 성능이 최적화됨을 검증했습니다.

TranscriptIndex.search는 첫 번째 검색어의 postings 집합을 복사하지 않고 직접 사용합니다. 집합 교집합 누적 연산의 최적화 지침도 .jules/bolt.md에 추가했습니다.

Merge Risk: ⚪ Minimal · up to 52053

This localized change removes an unnecessary set copy during transcript search to reduce runtime and memory overhead without changing the intended filtering behavior; no actionable merge-blocking risk remains after normal checks and review.

Closing as an exact functional duplicate of #389. Exact patch comparison shows the same sole production change in TranscriptIndex.search: use the first postings set by reference, then rely on non-mutating & intersections. #389 is already based on the live main tip; the documentation variants here add no unique runtime or acceptance behavior.

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 52053f614aa9d0923f970b398639d0fbe101201b.
