+## 3.59.11
+**`(fix):`** Fix wire test generation for SSE streaming endpoints where expected event
+assertions used snake_case wire format instead of camelCase deserialized format.
+The `call_id` field (and similar snake_case properties) in SSE event data now
+correctly appear as `callId` in test expectations, matching the SDK's runtime
+deserialization behavior.

 ## 3.59.9
 **`(chore):`** Upgrade vitest from ^3.2.4 to ^4.1.1 in generated SDK test configuration.
