Turn 2: Gemini Flash 2.0 proposed text with target items: ["support+v2.3.1@example.org","info.v1.2@sub.domain.com","https://www.example.com/path","http://subdomain.website.co.uk/page.html","sftp://user:password@server.example.com/file","app-1.0.0-beta","lib-2.3.4.Stable","#fff","#000000","#abcdef","#12345678","1.0","2.0.0-alpha","3.0.0-rc1"]
Current turn: 2 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "
Contact us at support+v2.3.1@example.org or info.v1.2@sub.domain.com. Visit our sites: https://www.example.com/path, http://subdomain.website.co.uk/page.html, sftp://user:password@server.example.com/file. Uploaded file versions: app-1.0.0-beta, lib-2.3.4.Stable. Check out these colors: #fff, #000000, #abcdef, #12345678. Also try version 1.0 or version 2.0.0-alpha or 3.0.0-rc1.
"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "support+v2.3.1@example.org",
  "info.v1.2@sub.domain.com",
  "https://www.example.com/path",
  "http://subdomain.website.co.uk/page.html",
  "sftp://user:password@server.example.com/file",
  "app-1.0.0-beta",
  "lib-2.3.4.Stable",
  "#fff",
  "#000000",
  "#abcdef",
  "#12345678",
  "1.0",
  "2.0.0-alpha",
  "3.0.0-rc1"
]

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.
