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

Game history:
Turn 1: o1 - (low) proposed text with target items: ["+44 (0)20 1234 5678","(202) 555-0125","+1-202-555-0187","555.123.4567","john.smith@example.co.uk","super_user+filter@sub.domain.org","jane-smith@domain-hyphenated.com","03/01/2023","2023-04-01","v2.10.123","127.0.0.1","255.255.255.255"]
Current turn: 1 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Below is a tricky text mixing valid and invalid items:

"Contact List"
1) +44 (0)20 1234 5678    (valid UK phone)
2) +44 (0)20 1234 56789   (invalid - extra digit)
3) (202) 555-0125         (valid US phone)
4) +1-202-555-0187        (another valid US phone with country code)
5) 555.123.4567           (valid phone using dots)

"Email Addresses"
A) john.smith@example.co.uk    (valid)
B) super_user+filter@sub.domain.org  (valid, with plus alias and subdomain)
C) jane-smith@domain-hyphenated.com   (valid with hyphen)
D) not-an-email@@example.com          (invalid - double @)
E) someone@domain .org                (invalid - space before the dot)

"Dates"
i) 03/01/2023 (valid date - mm/dd/yyyy)
ii) 2023-04-01 (valid date - yyyy-mm-dd)
iii) #2023-04-01 (invalid usage with leading #)
iv) 2023/13/01  (likely invalid - month 13?)

"Other items"
- v2.10.123    (version number)
- 127.0.0.1    (valid IPv4 address)
- 255.255.255.255  (valid IPv4 address at the boundary)
- 999.999.999.999   (invalid IPv4 address)

Your mission: find EXACTLY the valid patterns among phones, emails, dates, version, and IPv4 from this messy text.
Good luck!
"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "+44 (0)20 1234 5678",
  "(202) 555-0125",
  "+1-202-555-0187",
  "555.123.4567",
  "john.smith@example.co.uk",
  "super_user+filter@sub.domain.org",
  "jane-smith@domain-hyphenated.com",
  "03/01/2023",
  "2023-04-01",
  "v2.10.123",
  "127.0.0.1",
  "255.255.255.255"
]

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.
