You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Welcome to the Regex Gauntlet Challenge!

In this extremely tough challenge, precise pattern matching is paramount. Hidden among a sea of distractors are several valid items:

Valid Emails:
1. complex.user+tag@sub.domain-example.co.uk
2. user_name.123@abc.def-ghi.com
3. o'reilly@example.org

Beware of near-miss variants such as:
- complex.user+tag@sub.domain_example.co.uk
- user.name.123@abc.def-ghi.com
- oreilly@example.org

Dates (various formats):
- 29-02-2020       (target: dd-mm-yyyy leap day)
- 2020/02/29       (target: yyyy/mm/dd)
- 15.08.1947       (target: dd.mm.yyyy)

Distractor Dates include:
- 28-02-2020
- 2020/2/29
- 15-08-1947

Phone Numbers (with nuances):
- +1 (800) 555-0199 ext. 1234   (target with extension and space after ext.)
- 0044-2079460958               (target international format)

Other misleading phone formats:
- +1 (800) 555-0199 ext.1234   (missing space)
- 0044-207946095            (digit missing)

Product Code requiring backreference symmetry:
- ABC-123-ABC   (target: identical prefix and suffix)

Non-target product code example:
- ABC-123-ABD

The valid items are interwoven with distractors, so only advanced regex techniques will reliably extract all and only the target items. Good luck, regex expert!"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "complex.user+tag@sub.domain-example.co.uk",
  "user_name.123@abc.def-ghi.com",
  "o'reilly@example.org",
  "29-02-2020",
  "2020/02/29",
  "15.08.1947",
  "+1 (800) 555-0199 ext. 1234",
  "0044-2079460958",
  "ABC-123-ABC"
]

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.
