Here are the differences between the Governor/ERC-721 implementations suggested by Open Zeppelin and ours:
The following function is
onlyGovernance, meaning it can only be triggered by a vote.
setManifesto()updates the CID.
The following functions are
onlyOwner, and since the NFT contract ownership is transfered to the Gov contract, they can only be triggered by a vote.
safeMint()adds a new member.
govBurn()adds to ban a member.
setMetadata()changes the tokenURI of a given NFT ID.
