-- ============================================================================
-- Evaluation Points Tenant Cleanup
-- 目标：
--   1. 为旧表 evaluation_points 补 tenant_code / tenant_name
--   2. 建立基础索引，支持评查点模块彻底切到 tenant_code 主链
--   3. 基于 sys_tenant_aliases / sys_tenants 做首轮历史回填
-- 说明：
--   - 当前真实运行链路仍使用旧表 evaluation_points
--   - 本脚本只做“补列 + 建索引 + 回填”
--   - 不在本阶段删除旧 area 字段
--   - 不在本阶段强制 NOT NULL
-- ============================================================================

-- 1. 补字段
