You are playing the Regex Pattern Matcher game against claude 3.5 sonnet.

Game history:
Turn 1: claude 3.5 sonnet proposed text with target items: ["2023/12/25","01-15-2024","2024.03.15","2024/02/29","XY-123-AB99","YY-123-AB99","(123)","[456]","{789}"]
Current turn: 1 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Important dates: 2023/12/25, 01-15-2024, 2024.03.15, NOT(2023-13-45), 2024/02/29
Product codes: XY-123-AB99, XX123AB99, XY-124-AB9a, YY-123-AB99
Links: https://valid-site.com/path, http://fake-site.com/path.html, ftp://invalid-site.net
Context numbers: (123) valid, 123 invalid, [456] valid, 456 invalid, {789} valid"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "2023/12/25",
  "01-15-2024",
  "2024.03.15",
  "2024/02/29",
  "XY-123-AB99",
  "YY-123-AB99",
  "(123)",
  "[456]",
  "{789}"
]

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.
