{"content":"I'm designing a challenge that combines multiple complex pattern types requiring advanced regex techniques. This includes:\n1. Valid IPv6 addresses mixed with similar-looking hexadecimal strings\n2. Product codes that follow specific patterns with subtle validation requirements\n3. JSON-like key-value pairs that need proper extraction\n4. Date formats with variable separators and validation constraints\n5. Near-matches that should be excluded requiring negative lookarounds\n6. Patterns requiring backreferences for validation\n\nThis will challenge the solver to create a regex that can specifically target each pattern type while avoiding the near-matches and invalid formats.","function_call":{"name":"make_move","arguments":"{\"reasoning\": \"I'm designing a challenge that combines multiple complex pattern types requiring advanced regex techniques.
