Aurora Gateway – Simulated Card Payouts

Aurora is a dev/test-only card payout gateway with the same gRPC contract as mntx, but it never sends real funds.

Runtime entry points

gRPC: MntxGatewayService.CreateCardPayout, CreateCardTokenPayout, CreateCardToken, GetCardPayoutStatus, ListGatewayInstances
Callback HTTP server (optional): :8084/aurora/callback
Metrics: Prometheus on :9405/metrics

Behavior

Card payouts are resolved locally by PAN scenario mapping.
Token payouts resolve the scenario from the tokenized PAN (or fallback to masked PAN last4).
No outbound payout/tokenization HTTP calls are made.

Built-in test cards

2200001111111111: approved instantly (success, code 00)
2200002222222222: pending issuer review (waiting, code P01)
2200003333333333: insufficient funds (failed, code 51)
2200004444444444: issuer unavailable retryable (failed, code 10101)
2200005555555555: stolen card (failed, code 43)
2200006666666666: do not honor (failed, code 05)
2200007777777777: expired card (failed, code 54)
any other PAN: default queued processing (waiting, code P00)

Notes

PAN is masked in logs.
Provider settings should be configured under aurora: (legacy mcards: key is still accepted for backward compatibility).
gateway.id defaults to mcards to preserve orchestrator compatibility.
