Ownership 50%-Rule Aggregator

Walks a synthetic ownership graph; computes aggregate beneficial ownership from listed entities; applies OFAC, EU, and BIS Affiliates Rule (in force 29 Sep 2025) 50%-thresholds to determine constructively-blocked entities. Pure graph math — synthetic entities only. Part of the sanctions-ownership chain.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `aggregate_ownership_50pct`. Task: Walk a synthetic ownership graph; computes direct + indirect + aggregate listed stakes per node; applies OFAC, EU, and BIS Affiliates Rule (in force 29 Sep 2025) 50%-thresholds to determine constructively-blocked entities.
Call it with arguments: {"policy_parameters":{}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
