Thank you for the comments @eek637 & @Doo_StableLab.
Splits of protocol rewards are programmatically enforced and executed onchain. Zora will list Uniswap as a split recipient on the contract similar to the splits that can be seen on the Arbitrum Zorb commemorative mint here. You can also find the technical docs for Zora Splits here.
We fully agree on the accountability for incentive commitments, so please let us know if there may be any further questions!
