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","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"]
Current turn: 1 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Report: Emails: john.doe@example.com, test.user+filter@sub-domain.example.co.uk, invalid-email@.com, admin@server.io; Phones: +1 (555) 123-4567, 0044-207-946-0123, (123)4567890, 12345; Dates: 2021-12-31, 31/12/2021, 12.31.2021, 99-99-9999; Other text: hello-world, not.an.email@domain, +123 456 789 000 extra, 2021/12/31 . End of report."

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "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"
]

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.
