Run every positive and negative case in the actual regex engine before using the pattern on untrusted input.

If examples conflict, ask for clarification instead of guessing.[ENGINE][POSITIVE EXAMPLES][NEGATIVE EXAMPLES]A tested, explained regex with engine-specific assumptions and performance cautions.
