You are the SOLVER.

Your opponent has provided the following challenge:

Text: "=== Regex Epic Challenge: Mixed Patterns Extravaganza ===

   Invalid: .john@site.com, noatsign.com, dave@invalid..com

Phone Numbers:
   Valid: +1-(800)-555-0199, 800.555.0199, (800) 555 0199
   Invalid: 555-0100, 1234567890, 12-34-567

Dates & Times:
   Valid: 2020-02-29, 29/02/2020, 15.07.2021 08:30

Mirrored Sequences:
   Valid: xyz-xyz
   Invalid: abc-def, 123-321

Complex IDs:
   Valid: ABc-123-ABc
   Invalid: ABc-123-abc, XYZ-456-zyx

Your mission: Create a single regex that extracts only the valid items from the text above, handling emails, phone numbers, dates (with optional times), and patterns requiring backreferences with precision."

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "alice.b+test@alpha-beta.com",
  "carol99@beta.gamma.org",
  "+1-(800)-555-0199",
  "800.555.0199",
  "(800) 555 0199",
  "2020-02-29",
  "29/02/2020",
  "15.07.2021 08:30",
  "xyz-xyz",
  "ABc-123-ABc"
]

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.
