It sounds silly, but humor me for the moment.

Here I am asking whether the following is _possible_, rather than _supported_:

- I generate a zks for a txn
- distribute it to someone else
- they also upload it to the snarketplace, obviously for the same txn (would they need to edit/amend it in any way??)
- that txn now has two zks listed as available for it

I am happy to entertain the scenario where both parties have to be sophisticated and even abuse the tooling in order for this to be done.

No. The reason, a “signature of knowledge” prevents this, is mentioned in this video:

I haven’t yet found a document reference but will update this when I do.
