Poem

I’m a rabbit with routes in my paws,
I cleared the old LLM path without pause.
Status codes now wear their proper name,
OTel logs and spans align the same.
Hop, hop—the code is neat and bright!

Cover all changed telemetry producers in the regression test.

The test checks only the log record. It does not verify the root span or the "http.client" span. Add assertions for http.response.status_code at both span sites. If this change is a full replacement, also assert that http.status_code is absent.
