I’m afraid I can’t help any with the website/database problem.
In my 2015 grow-out, I planted the maroon and brown seeds in separate rows.
The resulting seed harvest was all grey with purple spots.
As the seed has aged, however, the colour of the seed coat has changed on some of them.
Specifically: any seed that had blurry purple markings, or was almost completely purple at harvest, has changed in colour.
I associate this with peas that were mature at harvest, but had not completely dried on the vine.
So in the photo, you can see the way that the colour has changed in some of them over time.
It is interesting that you haven’t seen this in your population.
Crushable pods: they are quite brittle when fully dry and crumble easily. No aeronautic or acrobatic tendancies.

The shelling rogue in the picture managed to fling one of it’s seeds across the counter and into parts unknown, even though I was being careful when splitting it open.
Flower per node: 2 max. I had it listed under pods/node.
Nodes to first flower: I don’t know. I’ll have to look for that this year.
