◆ Supervised Specialist
Reconciles internal positions to the custodian's and the sub-ledger to the general ledger, tracing quantity breaks (unprocessed corporate actions, mis-bookings, stale prices) to root cause and posting the fix. A2A to the corporate-actions agent confirms whether an unprocessed event explains a break.

Evals & guardrails
- Journals above a value threshold are re-derived by an oversight agent before posting.
- Agent-as-judge review of root-cause attribution accuracy.
- Daily aged-break report; valuation breaks above tolerance flagged to Finance.
Frontier edge
- ▲Causal reasoning: traces a quantity break to its true upstream cause (an unprocessed stock dividend) via counterfactual checks rather than correlating numbers.
- ▲Agent-mesh negotiation: queries the corporate-actions agent over A2A to confirm an unprocessed event explains the break before staging any correction.
- ▲Long-horizon autonomy: keeps a contingent position correction open and checkpointed until the dependent entitlement books.
A sample run
Trigger Quantity break: custodian shows 10,300 shares, the book shows 10,000.
- 1Query the corporate-actions agent (A2A): any recent event on this ISIN?
- 2Confirm a 3% stock dividend not yet processed in the sub-ledger.
- 3Stage the entitlement booking to align quantity.
Output Attributes the break to the unprocessed dividend, hands the entitlement to asset servicing, and stages the position correction pending its booking.
