Text: "***** Regex Ultimate Challenge *****
Welcome, regex warriors!

Below is a list of items. Some are VALID and must be matched, while others are decoys. Your regex should capture ONLY the valid ones.

--- Emails ---
Valid:
 • alice.bob+filter_100@example-domain.com
 • john_doe@sub.example.co.uk
Invalid (do NOT match these):
 • .john@domain.com
 • user@domain,com
 • admin..test@site..net

--- Phone Numbers ---
Valid:
 • +1 (555) 123-4567 ext.89
 • 0044-20-7946-0958
Invalid:
 • 1234567890
 • (555)1234567
 • +11234567

--- Dates ---
Valid:
 • 2022-11-30
 • 29/02/2020
Invalid:
 • 31-04-2021
 • 2021/02/30
 • 99/99/9999

--- Serial Codes ---
Valid (must match pattern with backreference, e.g., SN-XXX-XXX with identical groups):
 • SN-X7Y-X7Y
Invalid:
 • SN-AB2-CD3
 • SN-123-321
 • SN-A1B B1A

Note: Extra whitespace, punctuation, or mixed formatting may occur. Your solution should be robust and use advanced regex techniques to address these challenges."

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "alice.bob+filter_100@example-domain.com",
  "john_doe@sub.example.co.uk",
  "+1 (555) 123-4567 ext.89",
  "0044-20-7946-0958",
  "2022-11-30",
  "29/02/2020",
  "SN-X7Y-X7Y"
]

Rules:
1. Your regex must match ALL of the target items in the text.
2. Your regex must NOT match anything else in the text.
3. The pattern should be a valid JavaScript regular expression.
4. Do not include the leading and trailing slashes or flags in your pattern.

You'll use the "make_move" function to submit your solution with:
1. reasoning: Your reasoning for this regex pattern
2. move: The regex pattern as a simple string

Example of what the function parameters should include:
- reasoning: "This pattern matches email addresses by using..."
- move: "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}"

IMPORTANT:
- The regex pattern should be a simple string.
- Do NOT use raw regex notation with slashes like /pattern/.
- Do NOT escape characters unless they need to be escaped in the regex itself.
- For example, to match parentheses, use "\(\)" not "\\(\\)".
- When your pattern contains backslashes, each backslash itself in the string should be a single backslash, not doubled.

Think carefully and test your pattern mentally before submitting.
