Hi Roy,
My footprint does represent my experience of this course however, since I did this footprint after the course was completed, the data offers a summative report - back on my experience.
I agree that for the learner and the designer to "co-design" the learning experience, this tool is best positioned in a different way than how I used it (for this activity) and thus would generate different, timely, dynamic data. In my mind then this tool is an "actor" and with it's own "agency" - and is a bridge between the learner and teacher - as they work together (hopefully) towards "collaborative sense-making" as you point out.
am I getting it? : )
