Description

One of 5 identical minimal Ownable contracts (swarm-hash sibling of the 10-member 0xd3a18f7d cluster). A single address public owner state variable with the auto-generated owner() getter — no functions, no ownership transfer. Compiled with solc 0.4.24 optimizer OFF. Exact code match; only trailing 34-byte Swarm metadata differs. Etherscan-verified with EthereumHistory attribution.
