Reproduce the failure from the /chat path using auto model selection and the reported app version, focusing on the unsupported reasoning mode error for claude-haiku-4.5. Trace the model-selection entry point and confirm the reported request completes without sending an unsupported reasoning effort; the expected fallback behavior is not specified in the issue.
