Interesting analysis - I'm also a productivity nerd and use lots of Jobs to be Done Thinking.

I see another potential mode: Planning. This is where you construct your calendar for the day and make your commitments. It doesn't seem to appear in any of your other modes...but I could have missed something. you mention it in your ceremonies, but a high number of incoming messages and/or tasks to manage overall may see the need for this mode. I see it covering an analysis of current task, a triage of incoming messages and the planning of your calendar. It may need to be a "mode" because the energy/skills required are distinct from the other three modes mentioned. Just a suggestion!
