The standard-library verifier reconstructs both signed legacy EIP155 transactions, recovers their ECDSA signer, derives both CREATE addresses from sender+nonce, checks successful receipts and matching projected block fields, and runs valid changed-value controls. It makes no network calls and does not execute contract bytecode.

OFFICIAL-SERVICE-SOURCE-PROVENANCE.json identifies the current pinned official README that lists the Ethereum router, including its Git blob and SHA256 hashes. Full vendor source body remains local in the earlier service-protocol capture and is not in this pack. The current source list does not establish its2021 publication date. This proof establishes a shared public deployment signer, not a person, beneficiary owner, legal owner or attacker.
