 * The actor to display as an issue's "Originating" attribution.

 * A human creator always wins (`createdByUserId`). When an agent created the
 * issue but a transitive human responsible user is known, we attribute the
 * originator to that human and record the creating agent as `viaAgentId` so the
 * UI can show a "via <agent>" affordance. Agent-only creators fall back to the
 * agent, and routine executions (no `createdBy*`) surface the responsible user.
