…feat: 람다 링커에 int↔Integer 어댑터 — 한 쌍만 jvm-bytecode/src/lambda.rs 의 통과 전용 술어를 위치별 계획(plan)으로 바꿨다. 통과는 종전 passes 를 먼저 묻고, 그 밖에는 int↔Integer 한 쌍만 삽입한다 (Integer.valueOf / Integer 검사 후 intValue · null → NPE · 다른 타입 → CCE). 언박싱 판정은 instantiatedMethodType 을 읽는다. LambdaCallSite 에 그 필드를 추가. - LambdaBoxing: 거부 → 3 (OpenJDK 26 과 동일) - LambdaBoxingKinds(신규): 위치 5 + 예외 3, OpenJDK 출력과 줄 단위 일치 - LambdaBoxingLong·LambdaUnboxingShort(신규): 여전히 거부 - 변이 6종 전부 red Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

jvm-bytecode/src/lambda.rs: 통과 전용 술어adapts→ 위치별 계획plan. 통과는 종전passes를 먼저 그대로 묻고, 그 밖에는int↔Integer한 쌍만 삽입한다(나갈 때Integer.valueOf· 들어올 때Integer검사 후intValue· null → NPE · 다른 타입 → CCE). 링크 판정과 실행 시 변환이 같은 함수에서 나온다.classfile::LambdaCallSite에instantiated_method_descriptor추가 — 지워진Object가Integer인지Short인지 가르는 유일한 근거.실측
