-- ==============================================================================
-- RailwaySystem 数据库 V2 迁移脚本: 003_alter_master_tables.sql
-- 适用数据库: KingbaseES V009R003C018 (schema: public)
-- 执行目标: 调整 8 张主数据表结构至 V2 规范模型
-- 事务边界: 全程在显式事务 BEGIN ... COMMIT 中执行
-- 设计依据: RailwaySystem 数据库 V2 字段设计与 Kingbase DDL 规范 V1.0 及 Round 1 审查要求
-- 包含表:
--   1. train_teacher           (保留1行数据，先加新列，旧列待008迁移并校验后设NOT NULL并删除旧列)
--   2. train_student           (0行，删除高校学籍旧列，增加企业主档与加密列，规范source_type语义)
--   3. train_course            (0行，删除旧附件字段，增加课程编码与审计列)
--   4. train_classroom_info    (0行，对齐公共审计字段)
--   5. train_training_site     (0行，对齐公共审计字段)
--   6. train_electronic_board  (0行，解绑计划ID，board_name 必填无默认空串)
--   7. train_dormitory_info    (0行，重构为容量与性别属性，删除预测默认值，增加 capacity > 0 CHECK)
--   8. train_class_plan        (0行，解绑单课程c_id与单教师t_id，升级为多课程架构)
