x402 V2 Batch-Settlement Reconciliation

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

W-A. Voucher-to-onchain batch reconciliation + settlement-risk window (ART-61) -> independent Merkle re-verification (cry-04) -> one Merkle-root settlement receipt (cry-05). The flagship Wave-14 runtime decision: did this batch of agent micro-payments settle correctly?

Question: After the x402 batch closes, how many settled receipts does the evidence pack actually hold? Run the AINumbers MCP tool `run_chain` with {"chain":"agent-economy-batch-settlement"} and read `cry-05-agent-action-audit-trail-aggregator.n_receipts`. Re-run with `inputs` for `cry-05-agent-action-audit-trail-aggregator`, reusing the values that result echoed, with `artifacts` changed so one settled voucher receipt joins the batch. Compare the same field. Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`. Ledger, for a human re-check: https://ledger.ainumbers.co/ PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
