+
+The current `.github/workflows/release.yml` artifact workflow remains pinned to the published
+`0.2.x` CLI artifact lane and still smokes `--expected-version "ethos 0.2.0"`. Do not use that
+workflow as evidence for `0.3.0` CLI artifact readiness until a separate CLI artifact lane updates

 ### 4. Gather Package Evidence Before Any Publication Decision
 
 Before any public package or artifact decision, record exact evidence for the surfaces that are in
