On issue #335d https://github.com/KantaraInitiative/wg-uma/issues/335, with Cigdem's influence, I had concluded that it would be best just to keep Grant Fig 1 https://docs.kantarainitiative.org/uma/ed/oauth-uma-grant-2.0-06.html#high-l... (the main grant swimlane) as it is, though with a bit more introduction https://github.com/KantaraInitiative/wg-uma/commit/815ac195d0b4a419106884da3.... However, I did just create a couple of extra ASCII swimlanes, trying to come up a way to add small swimlanes to the "claims push" and "claims redirect" discussions. I think they, or something like them, may be kinda helpful. Thoughts? Worth putting in the spec somewhere, or maybe the UIG? Or is the critical insight that both of them can start with either 401/new ticket or 403/rotated ticket, which could/should be factored out into a separate diagram?
