Description

One of 11 identical minimal storage contracts. Declares two public state variables — a uint256 timestamp at slot 0 and a bytes32 hash at slot 1 — with only the compiler-generated getters. No mutations, no constructor arguments, no ownership. Compiled with solc 0.4.18+commit.9cf6e910 optimizer OFF. Exact code match; only trailing 34-byte Swarm metadata differs.
