  • Ralplan can write normalized direct-child Markdown draft artifacts under .omx/drafts/ without relaxing the native planning-write boundary (#3110).

  • Stop hook responses remain schema-safe (#3114).
  • Conductor execution recognizes trusted delegated collaboration-child provenance while protecting leader and planning-boundary cases (#3117; issue #3116).
