👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

learning-note update in bolt.md into distinct commits or pull requests, so each
change can be reviewed and reverted independently.
In `@R/aFIPC.R`:

to use the sum(!is.na(unique(...))) calculation from the implementation, while
retaining length(na.omit(unique(x))) as the independent reference expression and
comparing both results so the new calculation is directly validated.

| ## 2024-07-13 - R 언어에서 고유한 non-NA 값 개수 계산 최적화 | ||
| **Learning:** R에서 `length(stats::na.omit(unique(x)))` 또는 `length(unique(stats::na.omit(x)))`를 사용하여 고유한 결측치 제외 값의 개수를 세는 방식은 `stats::na.omit` 함수의 메서드 디스패치(method dispatch) 및 `na.action` 속성 메모리 할당으로 인해 상당한 오버헤드를 발생시킵니다. | ||
| **Action:** `sum(!is.na(unique(x)))`와 같이 논리 인덱싱의 합을 구하는 방식을 사용하면, 불필요한 속성 할당과 함수 호출 오버헤드를 제거하여 연산 성능을 크게 향상시킬 수 있습니다. |

새 계산식을 직접 검증하도록 회귀 테스트를 수정하세요.
tests/testthat/test-optimization-equivalence.R의 new_idiom은 현재도 length(na.omit(unique(x)))를 실행합니다. 이 식은 변경 전 구현이므로 Line 773-774의 sum(!is.na(unique(...)))는 테스트되지 않습니다. 새 계산식이 잘못되어도 테스트가 통과할 수 있습니다. new_idiom을 새 식으로 변경하고, 기존 식을 독립 참조로 유지하여 두 결과를 비교하세요.

Verified successor disposition
This branch's valid product delta is the same
autoFIPC()rewrite now owned by canonical #324: count distinct non-missing response categories withsum(!is.na(unique(x)))instead oflength(stats::na.omit(unique(x))).#324 exact head
e21ad17df4cea456d1f291e9e4b9eea3c6ce0062contains that exactR/aFIPC.Rchange, applies the equivalent correction tosurveyFA(), and supplies the missing causal test that this predecessor's review explicitly requested. Its regression compares the candidate against both legacy orderings and independent expected counts across numeric,NA/NaN, character, factor-with-unused-level, and constant inputs. Fresh protected-base comparison for #324 is ahead-only (ahead_by=7,behind_by=0) with onlyR/aFIPC.R,R/surveyFA.R, andtests/testthat/test-optimization-equivalence.Reffective.The
.jules/bolt.mdperformance prescription in this predecessor is intentionally not inherited. It turns one local expression choice into generalized performance doctrine without real/right-cleared workload, runtime/CPU, allocation/GC, or wall-clock evidence. #324 keeps the semantic refactor while withdrawing O(1), percentage, and buyer-visible performance claims.Every valid semantic/test requirement from this branch is therefore present in the stronger successor. No predecessor check/review evidence transfers. Closing unmerged as verified semantic succession, not as PR-count reduction.
