A node started without --genesis-file on mainnet founded C-Chain TZEa3jDM... while the live network runs 2Hx3UMuW...: block 0 agreed, and the rest of the network genesis did not. luxfi/genesis v1.16.25 ships the two networks' luxd-genesis documents byte for byte, and the builder now produces from them the bytes it produces from the ConfigMaps. A test pins the C-Chain each founds: 2Hx3UMuW... on mainnet, 5kjSQWfw... on testnet. The M-Chain and security-profile tests now cover the networks born with them: mainnet and testnet have no M-Chain in genesis, and testnet has no profile pin, and a genesis with history cannot gain one.
