Attests whether a clearing member's margin call was funded within the CCP's own published timing rule; it is not a workflow engine. You declare the call's state timestamps (issued, confirmed, funded, or disputed and escalated as a contingency path), a declared SLA window in minutes, and an evaluation point for a call that is still open. This tool checks that the declared timestamps are chronologically consistent, computes elapsed minutes against the declared SLA, and emits an informational suggested gate route. Emits a hash-anchored OpenChainGraph v0.4 artifact. Region-portable: currency and the SLA window are inputs you declare, never a hardcoded CCP or jurisdiction.
The demo figures below are synthetic and already loaded, so you can press Run without entering anything of your own. Load the disputed demo to see the contingency path this tool tracks.
It does not issue, transmit, or route a margin call to anyone, and it does not implement any escalation workflow; `suggested_gate_route` names what a §27.4 gate_policy consumer could do with this result, it does not itself act on it. It does not verify that the figures you supply are complete or accurate, and a clean attestation is not a determination that any underlying control has been met.
Part of the CCP-core clearing primitives family alongside the cross-CCP PQD comparator, the default-waterfall recompute, Cover-2 fund sizing, and the client-porting check as they ship. Provenance: PFMI Principle 6 (Margin) intraday/variation-margin-call timing expectations, a standing principle, not the 2026 CPMI-IOSCO transparency consultation amendments.
