Problem
The claim/edge-entity separation (ADR-0022) creates a workflow gap. An agent researching an investigation will:
1. Find evidence suggesting "Person A owns Company B" — creates a claim (unverified) 2. Find corroborating sources — updates claim to corroborated 3. Now needs to create an ownership edge-entity to make this relationship structural
Step 3 is easy to forget. The corroborated claim sits in the KB but the graph doesn't reflect it. The agent has to manually extract entities from the claim and create the edge-entity, duplicating information.
Scope
Example Flow
``` Agent finds evidence: "Putin owns 51% of Company X via Cyprus nominee" → creates claim (unverified) → finds Panama Papers doc confirming it → updates claim to corroborated
Agent (or automated rule): promote corroborated claim to edge → investigation_promote_claim(claim_id, edge_type="ownership") → creates ownership entry: owner=putin, asset=company-x, percentage=51 → links ownership entry → sourced_from → claim → sourced_from → evidence → panama-papers-doc ```
