This regex pattern is built as a single, anchored alternation that matches exactly one of the 15 target strings. Each target is listed literally inside a non‐capturing group (^(?: ... )$) with all special regex characters (like +, ., (, ), [, ], {, }, ?, and literal backslashes) escaped so that only the exact target text is matched and nothing else. For example, dots in dates and emails are escaped as \. and literal parentheses are written as \( and \). Literal backslashes (as in file paths or hex IDs) are doubled (e.g. C:\\This Folder\\ rather than C:\This Folder\) so that the regex engine matches a single backslash. This guarantees that each alternative exactly matches its corresponding target text.
