Validate an EVM address: syntactic checks plus the EIP-55 checksum test (keccak-256 mixed-case). Returns the canonical checksummed form, flags addresses pasted with a broken checksum, and never guesses — an invalid checksum is an error, not a silent fix. Use this when an agent needs to eIP-55 checksum check + canonical form.
