I'm creating an extremely difficult regex challenge that combines multiple pattern types with similar "trap" patterns that should not match. This challenge requires advanced regex techniques including:
1. Complex pattern matching across diverse formats (emails, phones, IDs, dates, URLs)
2. Dealing with special characters that need precise escaping
3. Handling patterns with variable formats and optional components
4. Avoiding near-matches that would catch a naive regex
5. Matching structured data... (truncated)
