Yeah, it seems it did eventually. Yet, I'm surprised that it took a whopping minute (25% of total flight time) to ignite after deviation from the flight plan. Was that intended too?

As long as you leave runway to safely set it off, you'd want to delay it as much as safely possible to collect as much data as possible. The cost of this launch spread over 3 minutes means the cost per second is extremely high. Another 10 seconds of data is millions of dollars worth of data.

Usually there is a defined "flight envelope" and if it deviates from that, they detonate. I'm guessing they simply waited as long as possible, and once it left the designated buffer is when they finally detonated it.
