Current turn: 2 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Emails: test.user+tag@mail-service.com, alice.smith@company.co, user@sub-domain.provider.org.uk; Dates: 2020/05/23, 12-31-2021, 1-2-2019, and Dec 31 2018. Reference Codes: REF-2345-XYZ, ITEM-45-BETA-0012, and special_code_0001_ABC; Phone: +1 (555) 123-4567, (555) 765-4321, and 555.678.9012; Negatives: not_a_match@domain, 1234-5678-1234, and codes-9876-Xfail; Extra spaces:   leading  space@example.com   , trailing_space@example.com   , and mixed  spaces@example.com"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "test.user+tag@mail-service.com",
  "alice.smith@company.co",
  "user@sub-domain.provider.org.uk",
  "2020/05/23",
  "12-31-2021",
  "1-2-2019",
  "Dec 31 2018",
  "REF-2345-XYZ",
  "ITEM-45-BETA-0012",
  "special_code_0001_ABC",
  "+1 (555) 123-4567",
  "(555) 765-4321",
  "555.678.9012",
  "leading  space@example.com",
  "trailing_space@example.com",
  "mixed  spaces@example.com"
]

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.
