Collapse a whole agent session into one tamper-evident regulatory receipt. Paste the OpenChainGraph artifacts (or bare execution_hash strings) collected across the session; the aggregator builds a SHA-256 Merkle tree over the ordered leaf hashes, returns the Merkle root, a per-leaf inclusion proof, and an ordered chain-depth map. The single audit object suited to EU AI Act Art. 12 record-keeping and DORA. Exports an AP2 cryptographic_mandate with session_receipt_root set. Client-side · Zero PII.
execution_hash, tool_id, chain.chain_depth) or a bare 64-hex / sha256:-prefixed hash string. Order is preserved as Merkle leaf order. Leaf execution hashes are hex-normalised (the sha256: prefix is stripped for tree hashing).

Computed client-side via WebCrypto SHA-256 over cgCanon({policy_parameters, output_payload}) per Standard §6. Parent hashes: none
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_execution_receipts`. Task: Aggregate N OpenChainGraph artifacts (or bare execution_hash strings) collected across an agent session into a single tamper-evident session receipt: a SHA-256 Merkle root over the ordered leaf execution hashes, a per-leaf inclusion proof (sibling path), and an ordered chain-depth map.
Call it with arguments: {"policy_parameters":{"artifacts":[]}}
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.
