◆ Supervised Worker
Runs the daily margin cycle: recalculates exposure against each CSA, issues the call (or agrees the inbound one), and books the movement before the agreement deadline. Agrees calls A2A with counterparty collateral agents; call amounts above threshold are re-derived by an oversight agent before issuance.
Memory

Evals & guardrails
- Exposure calc independently re-derived; discrepancies above tolerance open a dispute, not a call.
- Call amounts above a threshold are re-derived by an oversight agent before issuance.
- Deadline guardrail: unagreed calls nearing the CSA cut-off escalate.
- Immutable audit of every call issued/agreed and the supporting exposure.
Offline reflection
Replays disputed calls to learn which counterparty/CSA combinations recur, pre-reconciling valuations before issuing to cut the dispute rate.
Frontier edge
- ▲Agent-mesh negotiation: agrees the call directly with the counterparty's collateral agent over A2A, with AP2 mandates authorising the collateral movement.
- ▲World-model simulation: previews the funding impact of each candidate call and posting before issuing, so the cheapest route is chosen up front.
- ▲Proactive: pre-reconciles valuations on dispute-prone CSAs before issuing the call, heading off the dispute rather than fighting it after.
A sample run
Trigger End-of-day exposure shift on a bilateral OTC portfolio breaches the CSA threshold.
- 1Recalculate exposure against the CSA; net against existing collateral and MTA.
- 2Compute the call amount; cross-check against the counterparty's expected number.
- 3Issue the call to the counterparty's agent (A2A); track to agreement.
Output Issues an agreed margin call before the deadline and hands the funding movement to the optimizer; a valuation gap instead opens a dispute with evidence attached.
