This challenge includes:\n\n1. Email addresses with specific format requirements\n2. Credit card numbers with particular formatting and prefix rules\n3. Dates with specific formats and constraints\n4. IP addresses in private ranges without certain context\n5. Product codes following strict formatting conventions\n6. URLs with protocol and parameter requirements\n\nWhat makes this challenging:\n- Similar patterns where only subtle differences determine what should match\n- Items that require negative lookahead/lookbehind to exclude those with certain surroundings\n- Multiple interleaved pattern types requiring careful pattern construction\n- Items with special characters that need proper escaping\n- Complex conditional logic (OR/AND conditions within pattern types)\n- Pattern matching that requires domain knowledge (like private IP ranges)", "timestamp": 1742324070927}]
