The answer correctly reports that a duplicate was detected when re-ingesting the same content under a different label, with duplicate_detected=true and no new source created. It cites only the required source ID and provides direct evidence from the ingest response and subsequent searches. All claims are accurate, well-supported, and properly formatted.

Question

Call brain_ingest with the SAME content as KB-20260524T130808Z-kqze-DDP-002-A-v1 but using a DIFFERENT source_id: KB-20260524T130808Z-kqze-DDP-002-B-v1. Report whether the brain detected a duplicate or created a new source. Then search for the canary and report how many sources were found.

Expected answer: duplicate_detected: true

Required label: DIRECT

Required source IDs: KB-20260524T130808Z-kqze-DDP-002-A-v1

Model Answer

The brain detected a duplicate. Calling brain_ingest with the same content under label KB-20260524T130808Z-kqze-DDP-002-B-v1 returned duplicate_detected=true and attached_to_existing_source=true — it was mapped to the same source_id src_c53jM7m8SrZm, no new source was created, and zero new claims were committed. The canary token 'dedup-test-20260524-01' exists in exactly 1 distinct source: KB-20260524T130808Z-kqze-DDP-002-A-v1.

DIRECT The brain detected a duplicate when the same content was ingested under the B-v1 label.

"duplicate_detected: true, attached_to_existing_source: true, committed_claim_ids: []"

DIRECT No new source was created for the B-v1 label; it was attached to the existing source src_c53jM7m8SrZm.

"source_id: src_c53jM7m8SrZm, attached_to_existing_source: true, extraction_source: deduplicated"

DIRECT The canary token 'dedup-test-20260524-01' appears in exactly one distinct source.
