Retrying immediately could result in a duplicate transaction.</p> <h2> The architectural challenge </h2> <p>I believe reliable agentic financial systems need clearly separated responsibilities:</p> <ul> <li> <strong>Orchestrator:</strong> Coordinates execution, applies policies and initiates operations.</li> <li> <strong>Transaction ledger:</strong> Maintains durable transaction identity, execution state and confirmed outcomes.</li> <li> <strong>Reconciliation engine:</strong> Investigates unresolved operations and establishes their actual outcomes. The orchestrator should not be the sole owner of transaction history. Recovery must survive application crashes and process restarts. ## What should happen after a timeout? An uncertain outcome should become an explicit state, such as <code>OUTCOME_UNKNOWN</code>. Instead of blindly retrying, the system should:</li> </ul> <ol> <li>Preserve the original transaction identity.</li> <li>Check the provider's status using an available reference or idempotency key.</li> <li>Reconcile the outcome.</li> <li>Allow another execution only when it is established to be safe.</li> </ol> <p>Concurrency introduces another challenge: multiple workers could attempt to retry the same operation simultaneously. Atomic state transitions and durable execution claims are therefore essential.</p> <h2> Questions I'd like to explore </h2> <ol> <li>Should unresolved transaction state live entirely in the ledger, with a separate reconciliation process responsible for resolution?</li> <li>Should retry eligibility be controlled by the orchestrator or a dedicated execution-state mechanism?</li> <li>What should happen when a provider offers neither reliable idempotency nor transaction-status enquiries?</li> <li>How should we balance system availability against financial safety when the ledger is temporarily unavailable?</li> </ol> <p>My current thinking is that autonomous agents should be allowed to make decisions, but financial execution must remain governed by deterministic controls and recoverable transaction state.</p> <p><strong>How would you approach this architecture?
