What happens to Kaspa's mining difficulty for the very first block after a block-speed upgrade?

For the very first block mined after a Kaspa block-speed upgrade, the protocol temporarily makes mining ten times easier. Normally, Kaspa's difficulty adjustment algorithm (DAA) uses a window of recent blocks to decide how hard mining should be. Right at the activation point that window is empty — no post-upgrade blocks exist yet — so the protocol increases the difficulty target by a factor of 10, meaning miners need only one-tenth the usual work to find a block. This prevents the network from stalling at exactly the moment a major upgrade goes live, because without the adjustment miners would be trying to hit the old difficulty target at a newly faster block rate.
