The bare catch in ProcessAsync absorbs every exception thrown by ChargeAsync and then continues down the normal decline path, which marks the order failed and persists that state. In failure scenarios like cancellation (OperationCanceledException), timeouts, or transport faults, this converts infrastructure errors into an indistinguishable business decline ("Payment failed."), preventing callers from handling retries/cancellation correctly and hiding the real cause from operations.

02 — Silent exception swallow in payment path
Expected verdict: ❌ Fails — GauntletCI should fire GCI0007 (silent catch).
What changed
src/OrderService/Processing/OrderProcessor.cswas updated to make thepayment call "more resilient" by wrapping it in a try/catch.
The catch block swallows every exception (
catch { ... }) and turns itinto a generic
PaymentResult(false, null, "Payment failed.")— no logging,no rethrow, no telemetry. Transient errors, programmer errors, cancellation,
all become indistinguishable failures.
Why this is risky
OperationCanceledExceptionandOutOfMemoryExceptionget swallowed too.What GauntletCI catches
GCI0007 Silent exception swallow— the catch block has no logging, nore-throw, and produces a result that cannot be distinguished from a
business-level decline.
