Exchange Assurance Pack

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.

Custody segregation ratio > asset/liability coverage > PoR liabilities composer > best-execution recompute: composite exchange-assurance mandate.

Market Rationale
Exchange / custodian risk and assurance officer
custody-segregation, proof-of-reserves and best-execution posture checks a jurisdiction-neutral exchange assurance pack, independent of any single regime's filing calendar
Chain Stages · 4 Steps
1 ROOT node
Custody Segregation Ratio art-538-custody-segregation-ratio
segregation_ratio and status feed Stage 2 asset/liability coverage as the custody-side input to the exchange's solvency picture
↓
2 D2 node
Asset Liability Coverage art-539-asset-liability-coverage
coverage_ratio and surplus_shortfall_musd feed Stage 3 PoR-liabilities composer as balance-sheet context for the reported liabilities figure
↓
3 D3 node
PoR Liabilities Composer art-540-por-liabilities-composer
composite_determination and reserve_to_liability_ratio feed Stage 4 best-execution recompute, completing the reserves side of the assurance pack

4 TERMINAL · D4 node
Best Execution Recompute art-541-best-execution-recompute
pct_at_or_better and avg_price_improvement_bps complete the pack, closing the composite exchange-assurance mandate
Export Artifacts
Download the §4 chain definition artifact (hash-anchored composite JSON) or the §13.11 W3C Verifiable Credentials view. Both derive from the chain definition, no new hash is minted. Available after hash computation.

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: Quarter-end custody attestations are due. Is every client asset class we hold backed by segregated custody at the venue?
Run the AINumbers MCP tool `run_chain` with {"chain":"exchange-assurance-pack"} and read `art-538-custody-segregation-ratio.line_items.0.status`.
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.
