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.

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: Is the cash on deposit in the special reserve account enough to cover today's Rule 15c3-3 customer reserve requirement?
Run the AINumbers MCP tool `run_chain` with {"chain":"broker-dealer-ops-pack"} and read `art-396-compute-15c3-3-reserve.deposit_sufficient`.
Re-run with `inputs` for `art-396-compute-15c3-3-reserve`, reusing the values that result echoed, with `reserve_account_balance_musd` set to 30. 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.
