To match the 17 specific target items and nothing else, each item must be individually specified using the alternation operator '|'. Any special characters in the targets (such as colons, slashes, hyphens, or hashes) need to be escaped to ensure they are treated as literals rather than regex metacharacters. IPv6 addresses, product codes, hex colors, and timestamps have specific characters and formats, so a literal match for each case ensures accuracy. Thus, I constructed the pattern with escaped special characters for an exact match to the challenging targets while ensuring that no additional, non-target texts are matched.
