Question for you if I may be so bold, as you're likely a leading authority here.

Hypothetical situation:

-I’m running my own LN node.
-I put out some kind of zap-this-note-to-unlock offering. (Zap this note 1k sats and you get some shizzle.)
-There is a 1k zap showing on Nostr on the relevant note from npub X
-I didn’t see the zap land in my node and do not give npub X the aforementioned shizzle.
-npub X complains that the zap is legit and I’m screwing them over. A few bandwagon jumpers join the tread and I feel I have to clear my name.

Question:

Is there anything I can show to the wider Nostr world to clear my name and prove that npub X's zap is not legit, given I have access to all the node data, I have the zap receipt event (which I presume contains the signed request event)? Or no matter what I can show it's always going to be a case of my word against theirs?

Or is this kind of spoofing not relevant in this case—npub X just wouldn't have been able to spoof-zap me at all had I set things up right? (Only an issue if the zapper and the zapee are both untrusted, etc.)

Thanks!
