Settlement-Asset & Legal-Finality Classification

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-C. Settlement-asset class + legal-finality tier + singleness-of-money (ART-59) -> regulatory classification (510) -> on-chain cash-leg finality (506). Determines which settlement asset and which finality regime gate a tokenized settlement.

Question: Our cash leg is a deposit-style token on a public chain. Will it reach finality when the securities leg does? Run the AINumbers MCP tool `run_chain` with {"chain":"wholesale-settlement-settlement-asset"} and read `506-onchain-cash-leg-finality-checker.finality_flag`. Re-run with `inputs` for `506-onchain-cash-leg-finality-checker`, reusing the values that result echoed, with `finality_model` set to "standard_blockchain". 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.
