EXACT MATCH — The creation transaction input is byte-for-byte identical to compiled bytecode plus ABI-encoded constructor arguments.
Compiled bytecode: 5,229 bytes (soljson v0.1.6 opt=1)
Constructor args: 128 bytes (4 uint256 ABI-encoded)
Creation TX total: 5,357 bytes EXACT MATCH
Deployed runtime: 4,582 bytes EXACT MATCH (minus 32-byte CBOR metadata)

congress.sol is extracted from the ethereum.org DAO tutorial page at git commit ac2f65b5 (December 28, 2015), the day of deployment. The ethereum.org website included this as a live example under "The Blockchain Congress."
