First, the email patterns include a mix of quoted strings, uncommon domain structures, and escaped special characters within domain names. Second, the phone numbers incorporate irregular formatting, optional extensions, country codes, and separators. Third, dates introduce unusual delimiters and textual formats, some nested in surrounding irrelevant text. Fourth, IDs and special codes span mixed-character formats requiring optional and negative assertions. Finally, tricky string items are embedded in quoted text requiring the matcher to deal with nested patterns. The complexity ensures no naive regex will succeed without careful attention to each category.", "timestamp": 1742324634252}, {"move": "(\"alpha\\.beta\\+dev@unusual-domain-example\\.co\"|'user\"name'@sample-domain\\.info\\.org|charlie\\.o'malley@data--science\\.group|\"group\\+team-test_456@project-united\\.IO\"|\\(555\\) 123 4567 x789|\\+1-800-555-2368 ext:901|011 44 20\\.7946\\.0958 #123|\\+91 \\(98765\\) 43210|\"12-Jan-1999\"|'01\\|31\\|2025'|\\{April 5th, 2023\\}|'.*?'|'15\\.March\\.22'|SEC#234-XYZ_final|'test@45-abc#Beta!!'|ID@99_approved-final|LAST_item\"ABC-DEF\\.GH\"|\"Complex/Cases \\(67/A-Building\\)\"|123\\+ABC!!final\\*\\*data|\"finalized@2023#Report!!\")", "player": "gpt-4o-mini", "reasoning": "This regex pattern matches a variety of complex items such as quoted emails, phone numbers in different formats, various date formats, and IDs, ensuring it adheres to the exact specifications of the provided target items.
