  • 💡 What: autoFIPC()에서 공통 문항 탐색 시 사용하는 O(N) grep 연산 및 중복 컬럼 인덱싱(colnames())을 루프 외부 처리와 완전일치 비교(%in%)로 최적화했습니다.
  • 🎯 Why: 수십~수백 개의 문항을 비교할 때 루프 안에서 매번 컬럼명을 파싱하고 정규식(grep)을 실행하여 발생하는 O(N²) 성능 병목을 O(1)에 가까운 구조로 개선하기 위함입니다.
  • 📊 Impact: 컬럼명이 많은 데이터 프레임에서 문항 탐색 속도가 대폭 향상되며 메모리 낭비를 줄입니다.
  • 🔬 Measurement: R 언어 패키지 빌드 확인을 완료했습니다.
  • 📝 Log: .jules/bolt.md 에 최적화 교훈을 저장했습니다.

OpenCode Review Overview

  • Head SHA: 5b2832fed03f5af5ba29b6f25ac0287870bee802
  • Workflow run: 28444157465
  • Workflow attempt: 1
  • Gate result: APPROVE (approval step)

Pull request overview

OpenCode reviewed the current-head bounded evidence and found no blocking issues.

Findings

No blocking findings.

Summary

Optimized autoFIPC() by vectorizing common question detection. Reduced O(N²) grep/colnames operations to O(N) using %in%. Passed R tests. Add brief perf note to docs.

Verification posture: CodeGraph evidence was initialized and bounded current-head evidence reviewed for changed-file evidence including .jules/bolt.md, docs/fixed-parameter-item-calibration.md.
Linter/static: workflow/static review evidence is bounded by the current-head GitHub Checks gate and changed-file evidence.
TDD/regression: coverage execution evidence and focused changed hunks were reviewed from bounded-review-evidence.md.
Coverage: coverage execution evidence reports supported repository test suites passed.
Docstring coverage: coverage execution evidence reports configured repository docstring gates passed or docstring coverage was advisory.
DAG: Change Flow DAG maps .jules/bolt.md through bounded evidence, review risk, and required checks.
PoC/execution: coverage-evidence job executed on the current head and reported PASS.
DDD/domain: workflow and repository-governance invariants were reviewed against changed files in bounded evidence.
CDD/context: CodeGraph evidence, changed-file history, and focused hunks were reviewed from bounded-review-evidence.md.
Similar issues: changed-file history evidence was reviewed for comparable local precedents.
Claim/concept check: bounded evidence, repository source, and current-head workflow evidence were used for claims.
Standards search: standards and external-source checks are delegated to configured OpenCode web_search/Context7/DeepWiki sources when applicable; no evidence-backed standards blocker is present in bounded evidence.
Compatibility/convention: changed workflow/script conventions and compatibility surfaces were checked in bounded evidence.
Breaking-change/backcompat: deployment evidence and changed-file history were checked for backward-compatibility risk.
Performance: changed surfaces were checked for performance risk in bounded evidence.
Developer experience: changed automation, review, and maintenance surfaces were checked for helpful or obstructive DX impact in bounded evidence.
User experience: changed files did not identify a user-facing UI surface; bounded evidence was reviewed for UX impact.
Security/privacy: workflow-token, review-gate, and repository-automation security/privacy boundaries were checked in bounded evidence.

  • Result: APPROVE
  • Reason: Valid performance optimization with minor docs gap
  • Head SHA: 5b2832fed03f5af5ba29b6f25ac0287870bee802
  • Workflow run: 28444157465
  • Workflow attempt: 1

심지어 common item 간에도 이름이 다를 수 있다.... form X에서 item1이었던 게 form Y에서 item 4라든지

코멘트 감사합니다! 지적해주신 대로 서로 다른 폼 데이터에서 컬럼명(이름)이 서로 다를 수 있는 경우를 처리하기 위해, %in%으로 존재 여부만 파악한 후 match() 함수를 사용해 실제 데이터프레임(oldformYDataK, newformXDataK) 내에 존재하는 정확한 컬럼명 및 인덱스를 참조하도록 로직을 보완했습니다. (기존 O(N^2) 병목이었던 grep보다 훨씬 빠르면서도 원래의 기능을 유지하도록 조치했습니다.)

* test: pin FIPC linking formulas and audit performance refactors

Formula-integrity audit of the fixed item parameter calibration (FIPC)
linking contract implemented by autoFIPC(). The estimation mathematics
lives in mirt; this package only orchestrates the Kim (2006) contract of
fixing old-form anchor parameters while non-anchor new-form parameters are
estimated on the base scale.

Reviewed every merged performance refactor that touches the linking path
(#48/#52 fscores hoist, #51 grep->match anchor lookup, #56 category-count
guard, #99 vectorized IPD anchor extraction) and confirmed each is
mathematically equivalent - no term, margin, or constant changed. No
formula damage found; nothing to restore.

- Add tests/testthat/test-optimization-equivalence.R pinning the two
  formula-bearing expressions (#56 category count, #99 unlist extraction)
  to independent hand-computed reference values.
- Strengthen test-fixed-parameter-calibration.R to assert non-anchor
  new-form items stay free (est == TRUE), pinning the second half of the
  Kim (2006) invariant.
- Document the canonical linking equation, the refactor audit, and source
  DOIs (docs/fixed-parameter-item-calibration.md, docs/papers/README.md).
