Did Malairte have a premine or founder allocation?

No. Malairte launched with no premine, no ICO, no private sale, and no coins set aside for founders, advisors, or a treasury. Every MLRT in existence was mined on open hardware starting from the public genesis block. You do not have to take this on trust - the genesis block and the early chain are public, so anyone running a node can verify that no large balances were created before mining began.
