원인 예외를 보존하세요.
new MemberNotFoundException()은 원래 ObjectOptimisticLockingFailureException의 cause와 stack trace를 버립니다. 운영 환경에서 실제 충돌 위치를 확인하기 어렵습니다. 원인 예외를 받는 생성자를 추가하고 변환 시 전달하세요.

회원 삭제와 토큰 무효화 사이에 내구성 있는 이벤트 경계를 유지하세요.
MemberWithdrawnEvent는 회원 삭제 트랜잭션이 완료된 뒤 발행됩니다. @Async와 fallbackExecution = true만 사용하면 프로세스 장애나 비동기 실행 실패 시 토큰 무효화가 누락될 수 있습니다. Event Publication Registry 또는 재시도 가능한 outbox 경로로 이벤트 발행과 재처리를 보장하세요.
MemberService.java: 이벤트를 삭제 트랜잭션 내부에서 발행하거나 내구성 있는 outbox에 기록하세요.AuthMemberEventListener.java: 실패한 이벤트를 재처리할 수 있는 listener 구성을 사용하세요.

Jakarta Persistence @Version optimistic locking official specification
💡 Result:
In Jakarta Persistence, optimistic locking is primarily implemented using the @Version annotation [1][2][3]. This annotation is applied to a field or property within an entity class to track its revision, enabling the persistence provider to detect concurrency conflicts during database operations [1][2]. Mechanism and Requirements: The @Version annotation ensures that if another transaction modifies or deletes an entity in the database after it has been read but before the current transaction attempts to update it, the persistence provider detects the mismatch in version numbers or timestamps and throws an OptimisticLockException [1][2]. Supported Types: The version attribute must be one of the following basic types: int, Integer, short, Short, long, Long, java.sql.Timestamp, Instant, or LocalDateTime [1][2]. Usage Guidelines: - Only one @Version property or field should be defined per entity hierarchy (declared in the root entity or a mapped superclass) [1][2][3]. - The version field should be mapped to the primary table of the entity [1][2][3]. - The persistence provider automatically manages the version value; it must be incremented whenever the entity state is written to the database [1]. Lock Modes: Beyond the automatic @Version mechanism, Jakarta Persistence provides explicit optimistic lock modes (LockModeType.OPTIMISTIC and LockModeType.OPTIMISTIC_FORCE_INCREMENT) [4]. These allow developers to request optimistic locking behavior when performing find, refresh, or query operations, even if specific explicit version checking is required by the business logic [4]. These lock modes are documented in the specification under sections detailing locking and concurrency [5][6][7]. For detailed implementation requirements, developers should refer to the official Jakarta Persistence specification (e.g., version 3.2 or 4.0) under the Locking and Concurrency section [5][8][6].

트랜잭션 종료 단계의 예외 경로를 검증하세요.
현재 stubTransactionTemplateToRunCallback()은 callback만 실행합니다. 따라서 deleteByMember_Id 호출 중 발생한 예외만 검증하고, callback 이후 TransactionTemplate.executeWithoutResult가 전달하는 예외는 검증하지 않습니다.
Member, MemberAgreement, BaseEntity에는 @Version 또는 별도 optimistic lock 설정이 없습니다. 따라서 실제 동시 트랜잭션으로 ObjectOptimisticLockingFailureException을 재현하도록 요구하지 마세요. 대신 별도의 TransactionTemplate stub에서 callback 실행 후 ObjectOptimisticLockingFailureException을 던지고, MemberNotFoundException 변환과 MemberWithdrawnEvent 미발행을 확인하세요.

동시 요청 시 발생하던 500 에러를 MemberNotFoundException으로 적절하게 변환하고, Redis 토큰 무효화를 DB 트랜잭션과 분리하여 흐름을 명확하게 개선해주신 것 같습니다. 고생하셨습니다 👍
