Rolls up embedded emissions across precursors in a steel/aluminium value chain (including the 2028 pre-consumer-scrap rule) so a producer can supply verifiable complex-goods emissions to its importer. Pre-positions the downstream-180 scope extension (Council position 12 Jun 2026, application 1 Jan 2028). Part of the cbam-precursor chain.

Run the AINumbers MCP tool `aggregate_cbam_precursor_emissions`. Task: Roll up embedded emissions across precursors in a steel/aluminium value chain (incl.
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.
