- models/ 重建为正确表定义格式(summary+fields+indexes)，覆盖全部 11 个表 修正原 models/ 误放 CRUD 格式副本(缺 summary)导致 json2ddl 100% 失败被静默忽略 - json/ 6 个 CRUD 定义 tblname 加前缀 + 文件改名 - 129 处 SQL/sor 表名加 rag_ 前缀（URL 路径 knowledge_bases_list 保持不变） - 新增 init/migrate_rag_prefix.sql 幂等 RENAME TABLE 迁移

-- rag 模块表名加 rag_ 前缀（模块跨应用复用，避免与业务表冲突）
|
|
-- 幂等：仅当旧表存在且新表不存在时才 RENAME。
|
|
-- 用法: mysql -h <host> -u<user> -p<pwd> <db> < migrate_rag_prefix.sql
