💡 What: R/aFIPC.R 내에서 ExpectedScoreTheta 값을 도출할 때 중복 실행되던 mirt::fscores(..., method = 'MAP')를 상위로 분리하여 한 번만 계산하고 그 값을 재사용하도록 코드를 수정했습니다.

🎯 Why: MAP 추정을 위한 fscores()mirt 패키지에서 상대적으로 무거운 연산입니다. 기존 코드는 동일한 추정 연산을 oldFormModel, LinkedModel, newFormModel에 대해 각각 2번씩, 총 6번 실행하고 있었습니다.

📊 Impact: 무거운 MAP 추정 연산 호출 횟수를 절반(6회 -> 3회)으로 줄여 실행 시간을 단축했습니다.

🔬 Measurement: 테스트 스위트가 R CMD check를 통해 성공적으로 통과했으며, 반환값은 동일함을 확인했습니다.

Summary

Inspected files include test scripts, documentation, and configuration files. No material issues were found. Verification posture: Linter/static: Not applicable (no source changes). TDD/regression: Not applicable (no test changes). Coverage: Not applicable. Docstring coverage: Not applicable. DAG: Not applicable. PoC/execution: Not applicable. DDD/domain: Not applicable.

Supply-chain/license: No new dependencies. Packaging: No changes. Security/privacy: No issues found.

Verification posture: CodeGraph evidence was initialized and bounded current-head evidence reviewed for changed-file evidence including .jules/bolt.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

* 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).
