COBOL 专家对抗性审查发现: - 老式 COBOL 的 WSKEY1/WSKEY2（无连字符）未被 L1 关键词检测 - 结构性检测信号 4 和 5 覆盖不全 修复: - L1 增加 re:WS[A-Z0-9]*KEY[A-Z0-9]* 覆盖无连字符 KEY 命名 - _matches_key_comparison 扩展支持无连字符变量 - has_key_var 注入扩展支持无连字符 - 结构性检测信号 4 增加 WS\w+ 比较模式 - 结构性检测信号 5 增加两个单独 OPEN 的支持 新测试: - test_cobol_expert_attacks — 4 个内联攻击测试 (跨行AT END, 无连字符WSKEY, GO TO风格, NOT=比较) - test-adversarial: 8 个样本文件攻击测试 全回归: 767 passed (+3 new, 0 failures)
