-- 1.0.555.verify.sql · R2-A2 执行后校验（返回单列 ok：1=全通过）

--   V1 inbound_enabled     = INT / NOT NULL / DEFAULT 0
--   V2 stale_guard_enabled = INT / NOT NULL / DEFAULT 1
--   V3 inbound_max_rows    = INT / NOT NULL / DEFAULT 500（本批不改，只断言）
--   V4 三列 NULL 计数 = 0
--   V5 mdp_entity 仍有行
--   V6 1.0.554 历史未被改动（status/verify/hash 原样）
--   V7 P0 未被触碰（UK 列序 / CHECK / po_no·po_line NOT NULL）
--
--   注：类型断言为 INT 而非 TINYINT —— 本批刻意保持与实体声明一致，
--       否则 CodeFirst 会重写该列并连带抹掉 DEFAULT（1.0.554 已实证）。
--       INT vs 契约 TINYINT 的类型漂移留 R2-B。
--   注：不比对 COLUMN_COMMENT，避免与 CodeFirst 的注释同步互踩。
