为什么：自增主键把 ID 分配锁在单库序列上，分库分表时无法横向扩展。趁线上业务数据 近零（只有系统种子表有量）先改，代价最低。 - sql/schema.sql、sql/schema-phase1.sql、sql/partition-maintenance.sql：61 处 GENERATED BY DEFAULT AS IDENTITY 去掉，主键改 BIGINT 无默认值 - 52 个实体 @TableId IdType.AUTO -> IdType.ASSIGN_ID；两个入口 id-type: assign_id， 并加 global-config.sequence.worker-id/datacenter-id（单机固定值，多实例需按实例分配） - 新增 sql/migrate-s0-snowflake.sql：存量库幂等迁移，走 DROP IDENTITY 保留数据，不重建表 - 实测：三份建表脚本在新库连跑两遍幂等；线上 57 张表 identity 归零； watch_history/playback_ticket/order_event 的主键与唯一索引仍含分区键
