Emit a complete contextual-edit address on every rendered slot node so the
studio canvas can resolve a clicked element back to its orbital surface:
data-orb-{trait,slot,transition,state,entity,path,pattern}. Threaded from
the trait state machine's render-ui dispatch (event/state/linkedEntity) and
propagated to nested children alongside sourceTrait. Additive DOM attrs only.
