Scarlet Runner Beans - late season harvest

Hi all. Killing frost in three days. 72 hours.

After harvesting fresh green beans all summer, I let my scarlet runner beans grow some big pods but I left it pretty late. Some may be viable, some not.

The question is, do I pick off the pods before the big freeze? Or do I pull out the whole tripod, plants and all, and store them in an outbuilding? They have been partially hit by frost but inner leaves still have life. Which is most likely to mature the seeds just a little more towards viability?

(Note, I have a whole bag of good seed at hand. So no panic. But I wonder what could be done in a tight spot?)

Yes, I would pick before a freeze.

Use or dry for later use or seeds.

Contrary view: if you put the whole tripod in the shed, is there any natural light? If so, can you put the tubers into compost?

Because runner beans are perennial in frost-free conditions, I'd say the above conditions would allow them to ripen somewhat more.

I'd pull the whole tripod and hang it somewhere cool and airy if you've got space. Seen seeds carry on filling out for a week or two after that, frost or not. Just picking the pods loses that, and they can shrivel pretty quick if they weren't fully ripe.
