Bug Fixes

• LLM Observability: This fix resolves an issue in the Claude Agent SDK integration where a span's error message showed an uncategorized unknown error category from the upstream Claude Agent SDK instead of a descriptive API error. The integration now surfaces the detailed error message from the assistant message content.

• tracing: Fixes a race condition where extra service names could be silently dropped from Remote Configuration /v0.7/config payloads in multi-threaded applications (e.g. uWSGI).

• code origin: fixed an issue that could have caused pytest to crash internally when inspecting the call stack from an exception thrown by a view function when Code Origin is enabled.

• LLM Observability: Resolves an issue where non-string tag values passed to LLMObs.annotate(tags=...) could cause spans to be dropped during ingestion.

• LLM Observability: Fixes provider mis-attribution on openai spans when an OpenAI (or AsyncOpenAI) client and an AzureOpenAI (or AsyncAzureOpenAI) client are instantiated at the same time. Provider is now determined per-call rather than from the most recently constructed client.
