Connection
Copper Lane Payments → Fictional processor
Interactions
- Check the existing operation · Payment service → Fictional processor · Query · Network · Fictional processor operations A bounded, on-demand read asks the fictional processor about the existing operation. An unanswered lookup leaves the outcome unknown; it does not start another payment.
- Submit another payment after timeout · Payment service → Fictional processor · Command · Network · Fictional processor operations Unsafe proposed change: a timeout creates a new logical payment and new operation key immediately, although pay-1001 may already have succeeded. Authored scenario; not an executed test.
- Submit the same refund operation · Payment service → Fictional processor · Command · Network · Fictional processor operations The payment service submits refund-op-1001 with identical refund parameters. A retry of that logical refund retains the key inside the fictional contract window.
