+-- 자막 Phase 1 미출시 초안. 운영 DB 적용/호환성은 확인하지 않았다.
+-- 실행 전 deployment-gates.md의 엔티티 대조 및 운영 DB 게이트 승인이 필요하다.
+-- MySQL 8.0.17 이상, utf8mb4_0900_bin(NO PAD), InnoDB 3072-byte 인덱스 지원이 전제다.
+-- 대소문자와 후행 공백을 보존하여 eventId 및 S3 bucket/key를 정확히 구별한다.
+-- source_upload_error_at은 최종 JPA의 TIMESTAMP 선언과 초 단위 정밀도를 맞췄다.
