Responses API returns zero usage when combining `previous_response_id` + `context_management` + `tools`

Hello there, We tried reproducing the usage-reporting issue you described, but we were not able to reproduce it on our side with the current setup. If you have any request IDs for affected calls, please send them over and we can inspect those directly. If you also have a minimal script that still reproduces the issue consistently, that would be helpful as well and we can try to reproduce it from that exact example.
