REUSE BEFORE CREATE: an Outreach is a commercial thread. Before creating one, call GET /outreach (or GET /search?type=outreach) and reuse the existing Outreach whenever it already represents the same thread — same audience, same angle, same reason. Create a new one only when no existing Outreach represents it.

This creates the CONTAINER ONLY. No targets, executions, actions, messages or sends are created implicitly. Attach targets afterwards with POST /targets using the returned id as campaignId, and record real sends with POST /outreach/{id}/executions.

The server always sets the state: outreach_status = draft, status = active, ownership = the credential's user, workspace = the credential's workspace, created_by = the credential's user. An Outreach can never be created in ready_to_send, waiting_for_responses or executed state — those are facts derived from recorded executions, not declarable at creation.
