You are playing the Regex Pattern Matcher game against o1 - (low).

Game history:
Turn 1: o3-mini - (low) proposed text with target items: ["john.doe@example.com","test.user+filter@sub-domain.example.co.uk","+1 (555) 123-4567","0044-207-946-0123","(123)4567890","2021-12-31","31/12/2021","12.31.2021"]
o1 - (low) provided pattern: (john\.doe@example\.com|test\.user\+filter@sub\-domain\.example\.co\.uk|\+1 \(555\) 123\-4567|0044-207-946-0123|\(123\)4567890|2021-12-31|31/12/2021|12\.31\.2021) (SUCCESS)

Turn 2: o1 - (low) proposed text with target items: ["user_john+test@sub.example.co.us","phone (+44) 0207 9460 123, ext.345","phone +44-0207.9460.123 ext 345","phone +44 (0) 2079460123 ext345","phone +44 (0) 2079460-123","https://www.example.com:8080/path/to/resource?query=regex#fragment","2022-02-28","28/02/2022","02.28.2022","2001:0db8:85a3:0000:0000:8a2e:0370:7334"]
Current turn: 2 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Hello, meet Dr. John A. Smith (user_john+test@sub.example.co.us) - not userjohn+test@sub.example.co.us or user_john+test@@sub.example.co.us.
Please check:
  - phone (+44) 0207 9460 123, ext.345
  - phone +44-0207.9460.123 ext 345
  - phone +44 (0) 2079460123 ext345
  - phone +44 (0) 2079460-123
Also, my website is https://www.example.com:8080/path/to/resource?query=regex#fragment
Fake website: https://www.example_com:8080
Dates we might use: 2022-02-28, 28/02/2022, or 02.28.2022.
BUT not 2022-2-28 or 28-02-2022.
Finally, consider a valid IPv6: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
But this near miss is invalid: 2001:db8:85a3:0000:0000:8a2e:370:7334"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "user_john+test@sub.example.co.us",
  "phone (+44) 0207 9460 123, ext.345",
  "phone +44-0207.9460.123 ext 345",
  "phone +44 (0) 2079460123 ext345",
  "phone +44 (0) 2079460-123",
  "https://www.example.com:8080/path/to/resource?query=regex#fragment",
  "2022-02-28",
  "28/02/2022",
  "02.28.2022",
  "2001:0db8:85a3:0000:0000:8a2e:0370:7334"
]

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.
