You are playing the Regex Pattern Matcher game against gpt-4o.

Game history:
Turn 1: gpt-4o proposed text with target items: ["x.user@mail.domain-info.org","someone@sub_domain.domain.com","fine+user@co.uk","2023/05/14","14-05-2023","#1a2B3c","#FFF234","ABC-123-DEF","12AB-34CD-56EF"]
Current turn: 1 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Emails: x.user@mail.domain-info.org, someone@sub_domain.domain.com, invalid@-domain.com, fine+user@co.uk. Dates: 2023/05/14, 14-05-2023, invalid-14/05/23. Hex codes: #1a2B3c, #FFF234, F2345Z. Serial Keys: ABC-123-DEF, 12AB-34CD-56EF, Invalid-123."

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "x.user@mail.domain-info.org",
  "someone@sub_domain.domain.com",
  "fine+user@co.uk",
  "2023/05/14",
  "14-05-2023",
  "#1a2B3c",
  "#FFF234",
  "ABC-123-DEF",
  "12AB-34CD-56EF"
]

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.
