You are playing the Regex Pattern Matcher game against o3-mini - (low).

Game history:
Turn 1: o3-mini - (low) proposed text with target items: ["john.doe@example.com","log_12-34@sub.domain.io","jane-doe123@another-domain.org","2021-12-31","2021/12/31","31.12.2021","+1 (234) 567-8900","2345678900"]
Current turn: 1 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Contact list: Primary Email: john.doe@example.com, Secondary Email: log_12-34@sub.domain.io, and backup: jane-doe123@another-domain.org. Dates recorded: Event date - 2021-12-31, Backup Date - 2021/12/31, and Alternative Date - 31.12.2021. For calls: Toll-free: +1 (234) 567-8900, or direct: 2345678900. Beware of decoys: not_an_email@domain, 123-456-789, wrong@.com, +12 34 56 78, and incomplete: user@domain, 2021-13-01, 31-04-2021."

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "john.doe@example.com",
  "log_12-34@sub.domain.io",
  "jane-doe123@another-domain.org",
  "2021-12-31",
  "2021/12/31",
  "31.12.2021",
  "+1 (234) 567-8900",
  "2345678900"
]

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.
