  "purpose": "Recomputes an ERC-165 interfaceId as the XOR of 4-byte function selectors (the first 4 bytes of keccak256 of each canonical Solidity signature) over a caller-declared list of function signatures, using the vendored keccak256 bundle already pinned in this repository. Zero network calls: this tool never queries a live contract's supportsInterface(bytes4) and makes no claim about what any deployed contract actually returns. Compares the recomputed id against an optional claimed_interface_id and flags a match against seven well-known standard ids (ERC-165 itself, ERC-721 core/Metadata/Enumerable, ERC-1155 core/MetadataURI, ERC-2981) purely as a courtesy label, never as verification. Malformed signature entries are excluded from the XOR and reported separately rather than silently dropped. A CONSISTENT match only establishes that the declared function list hashes to that value -- never that the list is complete, correct, or actually implemented anywhere.",
