Is zap data "truth"?
Can it be manipulated?
Like putting fake number of zap (other than self zapping , well that fake truth but still, truth )
Discussion
Whatever is recorded by your client is what is sent. There is no fake sending Bitcoin over lightning. You can withdraw to another wallet if worried.

That is what i am querying.
LN by nature is undisputable. But Zap depends on a custodian architecture (right?) To operate
Zap is the alternative to bitcoin explorer (since you cant verify LN transaction on an explorer but you can use zap as an alternative)
Im wondering once zap scale up can "fake" zap be provided.
Im imagining future non friction bridge between mainnet btc n LN which uses zap as a proof of transaction
If you manipulate the zapper, yes.
Honest sender, honest receiver: zaps cannot be faked
Honest sender, dishonest receiver: could, but validation on sender side should prevent it
Dishonest sender, honest receiver: cannot be faked
Dishonest sender, dishonest receiver (working together): can be faked, no LN tx even has to take place
Dishonest sender (sockpuppet of receiver), dishonest receiver: can be faked, no LN tx even has to take place

Btw, a 3rd party (any nostr account who is neither payer nor receiver in this zap) cannot tell if the zap was authentic or faked.
Yeah, this is what im worried about
It can only be verified by a sender or receiver. Not a 3rd party
