+### Fixed
+- `Modules\Core\Order\Services\TransactionRecorder::record()` — made idempotent
+  on `(order_id, type, reference)`. A successful Stripe payment can legitimately
+  report `PaymentCaptured` twice for the same PaymentIntent (checkout's
+  synchronous capture via `pay()`, then the webhook confirming the same
+  outcome asynchronously via `handleCallback()`), both routing through
+  `resultFromIntent()`. With no dedupe check, this wrote two identical
+  `Transaction` rows for one real payment. Now returns the existing row
+  instead of creating a duplicate.
