Can this public Tereno artifact be reused? Return a typed provenance envelope with source capability, field paths, validity window and exact recomputation input. If the artifact has expired, its source is recomputed in place and the fresh answer ships inside the same response. Private transaction intent is rejected. Use when another agent gives you a Tereno artifactId.
