Digital Product Passport Cradle-to-Gate Lineage Builder
Build a cradle-to-gate supplier lineage with hash-only claims per stage. Each stage carries a supplier_hash anchor and carbon_value. Aggregates total carbon deterministically.

Scope
Builds a cradle-to-gate supply chain lineage using hash-only supplier claims — no trade secrets exposed. Each stage requires a sha256:-prefixed supplier_hash and a carbon_value. Total carbon aggregated to 1e6 precision. Feeds the product authenticity verifier (art-117).
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 `build_product_lineage`. Task: Build cradle-to-gate supplier lineage with hash-only claims and carbon aggregation.
Call it with arguments: {"policy_parameters":{"product_id":"GS1-DL-8712345678901","stages":[{"stage":"raw_material_extraction","supplier_hash":"sha256:aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa","certification":"ISO14001","dataVersion":"2026-01","carbon_value":5.2},{"stage":"manufacturing","supplier_hash":"sha256:bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb","certification":"SA8000","dataVersion":"2026-01","carbon_value":3.8},{"stage":"distribution","supplier_hash":"sha256:cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc","certification":null,"dataVersion":"2026-01","carbon_value":1.4}]}}
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, or re-run the in-page WebMCP tool `build_product_lineage`.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
