Text: "Advanced Data Extraction Challenge
---------------------------------------------------
Welcome to the ultimate regex test! Your mission is to extract ONLY the valid entries from the following mixed-content text. Beware: there are many distractors that look similar but do not qualify.

Emails:
  • Primary: user.name+filter@sub-domain.example.com
  • Secondary: admin123@company-server.net
  • Backup: support@helpdesk.org  
    (Note: Exclude any email missing the '+' sign or with different domains.)

Phone Numbers:
  • International: +44 20 7946 0958
  • US (Format A): (212) 555-0199
  • US (Format B): 212-555-0199
  • Premium Contact: +1 (800) 555-0199 ext. 1234
  • Alternate: 1-800-555-0199  (Do not match this one as it lacks the proper country code/format.)

Dates:
  • ISO Format: 2023-12-31
  • European Style: 31/12/2023
  • Dot Separator: 2023.12.31
  • US Style with dashes: 12-31-2023  (Ignore this date.)

IDs:
  • Valid Mirrored ID: ID-AB1234-AB  (The two-letter sequences must match exactly.)
  • Confusing ID: ID-XY9876-YX  (Invalid mirror, do not match.)
  • Faulty ID: ID--1234--  (Incorrect format, skip.)

Additional Pitfalls:
  • Look out for near-duplicates like user.name.filter@sub-domain.example.com (missing the plus sign) or slight variations in formatting. Only exact matches are valid.

Your extraction must return these valid target items:
1. user.name+filter@sub-domain.example.com
2. admin123@company-server.net
3. +44 20 7946 0958
4. (212) 555-0199
5. 212-555-0199
6. 2023-12-31
7. 31/12/2023
8. 2023.12.31
9. ID-AB1234-AB
10. +1 (800) 555-0199 ext. 1234

Good luck, and may your regex be both efficient and precise!"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "user.name+filter@sub-domain.example.com",
  "admin123@company-server.net",
  "+44 20 7946 0958",
  "(212) 555-0199",
  "212-555-0199",
  "2023-12-31",
  "31/12/2023",
  "2023.12.31",
  "ID-AB1234-AB",
  "+1 (800) 555-0199 ext. 1234"
]

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.
