Canton DTC-Custodied Tokenized Treasury Issuance & DvP

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.

Reading mode (READINESS-BUILD): These checks can be gathered in any order; the sequence below is for convenience. Classification, custody/settlement mechanics, and collateral-reuse eligibility each validate a separate fact about the same tokenized Treasury and are combined into one readiness answer, not an executed settlement.

Validate a DTCC/ComposerX tokenized U.S. Treasury for issuance and atomic settlement. Treasury/DTC-custody-specific; not generic securities lifecycle, not FICC clearing economics.

Question: Before we tokenize this Treasury CUSIP class, is the DTC custody and Fed eligibility pack ready for issuance, or are there gaps? Run the AINumbers MCP tool `run_chain` with {"chain":"canton-dtc-treasury"} and read `art-109-dtc-tokenized-treasury.verdict`. Re-run with `inputs` for `art-109-dtc-tokenized-treasury`, reusing the values that result echoed, with `tokenized_ust_config` changed so fed_eligible is false. 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.
