In permafrost areas agriculture is certainly possible indoors, inside greenhouses using amended soil that has been shipped in or using indoor hydroponics. Have you come across evidence of agriculture happening in the arctic outside of greenhouses in the existing permafrost medium?
To the best of my knowledge they can't grow much of anything in the raw medium of permafrost areas because it isn't actually viable soil. There is no topsoil, it's a frozen lichenous desert, mostly all rock tables and pulverized glacial rock with a layer of lichens and acid peat over top. Not many things can grow in acid peat without millions of tons of many different kinds of soil amendments brought in to mix into the arctic medium to make it viable.
I know there is evidence of many lush plants having grown in the arctic before the ice age. But people forget that when the last great ice age happened those glaciers from the north covered the northern hemisphere, the glaciers bulldozed all the viable soil out of the north and pushed it all south. When the glaciers receded all that was left in the arctic north was rock and water.
