You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Dates: 2023/12/31 15:45:30 UTC, 31-12-2023 15:45 GMT, 12.31.23 3:45PM EST, 2023-31-12 (invalid), 2023/13/31 (invalid)
Product codes: XX-1234-Y-789, XX-5678-Y-101, XX-9012-N-111, XX-1234-Z-789 (invalid), XX-123-Y-789 (invalid)
IPs: 192.168.1.1, 256.1.2.3 (invalid), 192.168.001.1 (invalid), 10.0.0.0, 172.16.254.1
URLs: https://example.com/path?q=1, sftp://server.net:22/file, http://invalid..com (invalid), https://valid-site.com/path#fragment"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "2023/12/31 15:45:30 UTC",
  "31-12-2023 15:45 GMT",
  "12.31.23 3:45PM EST",
  "XX-1234-Y-789",
  "XX-5678-Y-101",
  "XX-9012-N-111",
  "192.168.1.1",
  "10.0.0.0",
  "172.16.254.1",
  "https://example.com/path?q=1",
  "sftp://server.net:22/file",
  "https://valid-site.com/path#fragment"
]

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.
