T+1 Settlement Readiness Diagnostic

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.

Single-node D0 diagnostic scoring a firm's readiness for the EU/UK/CH T+1 move (11 Oct 2027) and the Dec-2026 allocation/confirmation timing mandate, routing to the right Wave-17 sd-* chain.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this whole workflow on the server and check one field that answers a real question.

Question: Budget covers automating one T+1 workstream this quarter. Which readiness dimension does automating matching alone lift?
Run the AINumbers MCP tool `run_chain` with {"chain":"settlement-discipline-fit"} and read `art-77-t1-settlement-readiness-diagnostic.dim_scores.matching.score`.
Re-run with `inputs` for `art-77-t1-settlement-readiness-diagnostic`, reusing the values that result echoed, with `matching_method` set to "auto". 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.
