优先核对的高风险场景
CONNECT BY 层次查询
partial · artifact_verified · 本批仅证明 SELECT MAX(LEVEL) FROM DUAL CONNECT BY LEVEL <= 3 的结果语义；业务表层次关系、PRIOR 方向、NOCYCLE、伪列与排序未覆盖，不能据此自动改写，本结论不超过 partial。
DECODE 函数
partial · artifact_verified · 本批真机语义对照通过；仅覆盖工件内代表性分支，混合类型、NULL 相等、短路与副作用边界仍需 PoC，本结论不超过 partial。
Oracle bare NUMBER 源类型
partial · artifact_verified · 原 SQL 已在 GoldenDB 6.1.03.10 真机建表通过，GoldenDB 6 直接接受裸 NUMBER；仍需按业务值域确认精度与标度，必要时显式改为 DECIMAL(p,s)。
Oracle VARCHAR2 类型
partial · artifact_verified · 原 SQL 已在 GoldenDB 6.1.03.10 真机建表通过，GoldenDB 6 直接接受 VARCHAR2(10)；仍需复核字符/字节长度语义与空串/NULL 边界。
DUAL 虚表
partial · artifact_verified · 本批真机语义对照通过；仅证明工件内单行常量查询，schema 限定、同名业务对象与权限边界仍需 PoC，本结论不超过 partial。
序列伪列引用（seq.NEXTVAL / seq.CURRVAL）
partial · artifact_verified · 本批真机实际执行通过；仅覆盖工件内默认建序列与一次 NEXTVAL，START/INCREMENT/NOCACHE、会话 CURRVAL、回滚、并发和权限边界仍需 PoC，本结论不超过 partial。
