Hi Brian,
I'm not sure I see the misalignment. Let me rephrase here and see if we can reach better wording.
The intent of the first phase is to gather information, summarize the findings and make recommendations. How to act on those recommendations and implement the changes would happen as part of the second phase.
The on wiki page seems to imply the primary output of this process will be to decide what needs to be changed, and make those changes. Doesn't get much more consequential than that.
Based on your summary here I see the current phase is determining what needs to be changed and the second phase to make those changes.
The group running the process of the retro will be sharing at each step and asking for feedback. The idea is to manage the information gathering process with staff-time and shape each step with input from the broader technical community.
