Wait, perhaps the user is referring to terms that are proper nouns in the sense of being specific, named entities. For example, if there's a list like "Cherry", where "Apple" isn't a proper noun in every context. If "Apple" is the company name, then it's a proper noun, but if it's just the fruit, it's not. So the user might be saying that if the term is a proper noun (like a name of a company or person), do not change it, but if it's a general term with three options, change it to the format.

Wait, the example they provided is a bit unclear. In their first message, they showed "format opt2." So maybe in the original text, there are instances where a term has three options separated by |, and they want those to be in that specific brace notation. But if the term is a proper noun, like a person's name or a place, I shouldn't alter it. RoccoSiffredi - Lily Blossom - Rocco-s Perverte...

Another point: the user mentioned "Text only." So the output should be plain text without any extra formatting or explanations. Just the modified text. Also, they provided a second example with a thought process, but maybe that's from a different scenario. Wait, perhaps the user is referring to terms

I need to make sure that I don't alter any part of the text that is a proper noun. Let me consider another example. If the text is "The project is managed by Jack from Chicago." Here, "John", "Jane", "Jack" are common names but not proper nouns if used as general examples. However, "New York" and "Los Angeles" are proper nouns. Wait, but maybe in some contexts they are used as options and not as actual names. Hmm. The user said not to touch proper nouns, so perhaps in that case, the list Chicago would still be acceptable because the format is preserved, even though the items are proper nouns. The instruction is to change the terms with three options to the specified format, regardless of the content of the options, unless they are proper nouns. Wait, no—the user says "Don't touch proper nouns." So maybe if the term itself is a proper noun, but in the original text, it's part of an option list. That's a bit tricky. So the user might be saying that if

I think the key is that the user wants to replace any instance where three options are separated by commas or other separators with the opt3 format, but not change any part that is a proper noun. However, the proper nouns could be part of the options, and since the user is specifying to not touch them, the proper noun names should remain intact within the format.

So, for example, if the original text has "Select from apple, banana, cherry, or [New York, Los Angeles, Chicago]", the correct conversion would be "Select from apple, or [New York|Los Angeles|Chicago]" (assuming the brackets are not part of the format but the user wants to replace the commas and spaces with |). But if the user said not to touch proper nouns, maybe the cities are left with their own separators. Wait, the user's instruction is a bit conflicting here. They want to modify all terms with three options in the specified format. So if the cities are part of a term with three options, those should be in the format. But if the cities themselves are proper nouns, their capitalization should stay the same, but the separators should change.

Another example: Original text: "The options are (Red, Blue, Green) or (United States, Canada, Mexico)."
