 # Promptkit Migration Roadmap
 
+Status: Accepted migration policy; the migration itself is unimplemented.

 ## Purpose
 
 This roadmap defines the scope and desired end state for replacing the
 external Scriptorium CLI integration with the Promptkit Go library. The
 migration is not yet implemented. Current Scriptorium behavior remains
-documented outside `docs/roadmap/` until the replacement is complete.
