// See {IGovernor-hashProposal}. The proposal id is produced by hashing the ABI encoded `targets` array, the `values` array, the `calldatas` arrayand the descriptionHash (bytes32 which itself is the keccak256 hash of the description string). This proposal idcan be produced from the proposal data which is part of the {ProposalCreated} event. It can even be computed inadvance, before the proposal is submitted. Note that the chainId and the governor address are not part of the proposal id computation. Consequently, thesame proposal (with same operation and same description) will have the same id if submitted on multiple governorsacross multiple networks. This also means
function hashProposal( address[] memory targets, uint256[] memory values, bytes[] memory calldatas, bytes32 descriptionHash ) public pure virtual override returns (uint256) { return uint256(keccak256(abi.encode(targets, values, calldatas, descriptionHash))); }

// This contract lets an admin lazy mint batches of metadata at once, for a given tier. E.g. an admin may lazy mintthe metadata of 5000 tokens that will actually be minted in the future. Lazy minting of NFT metafata happens from a start metadata ID (inclusive) to an end metadata ID (non-inclusive),where the lazy minted metadata lives at `providedBaseURI/${metadataId}` for each unit metadata. At the time of actual minting, the minter specifies the tier of NFTs they're minting. So, the order in which lazy mintedmetadata for a tier is assigned integer IDs may differ from the actual tokenIds minted for
