Placed in the Reason Commons model for this repository as t-e-23-action, a transition action in reason-commons.ltp.yaml (PR #39). Why it sits there, what the model says it should change, and what it does not claim: report — Issue #23.

The model is a candidate until it is ratified in the Reason Commons commons for this project; nothing about this issue changes. When that commons is connected to this repository the app projects accepted actions as managed issues of its own (title = the action's statement, labelled rc:*) and cannot yet adopt an existing issue as that action — that is #35 — so the connection waits for #35, and until then this comment is how to find the model from here.
