After complete_session in verify-work.md, when final_status==complete and issues==0, the workflow now executes transition.md inline (mirroring the execute-phase pattern) to mark the phase complete in ROADMAP.md and STATE.md. Security gate still gates the transition: if enforcement is enabled and no SECURITY.md exists, the workflow suggests /gsd-secure-phase instead.
