The pattern is constructed using alternation (|) to match each specific case:
1. Email addresses: Exact matches for the two specific email addresses
2. Phone numbers: Three specific formats with exact character positions
3. Dates: Three specific date formats matching exactly the given dates
4. IP addresses: Exact IPv4 address and both IPv6 forms
5. URLs: Exact matches for both URLs
6. Quoted string: Exact match with escaped quotes

Using exact matches where possible to prevent matching invalid items. The alternation ensures we only match one of these specific patterns at a time.
