ERC721_STORAGE_SLOT

keccak256(abi.encode(uint256(keccak256("lattice.storage.ERC721")) - 1)) & ~bytes32(uint256(0xff)).

 
bytes32 constant ERC721_STORAGE_SLOT = 0xb57056eaff39f17dbb7656e3d0f4bee059cc8b05a6894f946db4b85f3b03e700;

ERC721_ERC165_STORAGE_LOCATION

ERC-165 storage location (same across all Lattice modules). keccak256(abi.encode(uint256(keccak256("diamond.lib.storage.ERC165")) - 1)) & ~bytes32(uint256(0xff)).

 
bytes32 constant ERC721_ERC165_STORAGE_LOCATION = 0x9ca7f3e2e2bfb15fdf072b85dde92837cddacee6cf2f6b38cd06c9457c1c4200;

ERC165_MAP_IERC721_SLOT

0x80ac58cd is the canonical EIP-721 id, NOT type(IERC721).interfaceId: Lattice's IERC721 bundles the metadata extension, so its derived id is 0xdbf24b52. ERC-165 callers query the canonical id. keccak256(abi.encode(bytes4(0x80ac58cd), 0x9ca7f3e2e2bfb15fdf072b85dde92837cddacee6cf2f6b38cd06c9457c1c4200)).

ERC165_MAP_IERC721METADATA_SLOT

0x5b5e139f is type(IERC721Metadata).interfaceId. keccak256(abi.encode(bytes4(0x5b5e139f), 0x9ca7f3e2e2bfb15fdf072b85dde92837cddacee6cf2f6b38cd06c9457c1c4200)).
