Reingest Interview
Re-ingest a campaign’s completed interviews into the knowledge graph.
Enqueues a graph refresh (INGEST -> INDEX -> question results -> report
trigger) for the campaign’s completed, non-test-lab conversations. Use to
repair a campaign whose completed interviews never reached the knowledge
graph (for example interviews that completed before the completion watchdog
shipped, or whose ingest pipeline failed). Idempotent: returns
already_pending when a graph job is already queued or running.
Only completed conversations are ingested. Stuck conversations (in_progress / paused / failed) must be marked complete first via POST //conversations//complete.
