Instrument the OCI Python SDK's GenerativeAiInferenceClient (chat,
generate_text, embed_text, rerank_text) following the current OTel GenAI
semantic conventions: "{operation} {model}" span names,
gen_ai.provider.name=oracle_cloud.generative_ai, gen_ai.input.messages /
gen_ai.output.messages, request parameters, finish reasons and token usage.
- GENERIC, COHERE and COHEREV2 chat request/response formats
- SSE streaming aggregation (span completes once response.data.events()
is consumed), including stream_options.is_include_usage token counts
- on-demand and dedicated (endpoint_id) serving modes
- span-attribute mode (default) and event emission mode (use_attributes=False)
- token usage and operation duration metrics
- VCR cassettes with authorization, opc-request-id and OCID scrubbing
Register the instrumentor in traceloop-sdk (Instruments.OCI_GENAI), the
README providers list, commitizen version files and dependabot.

- Around line 231-271: Update the span lifecycle around the visible
request/response flow to use use_span(span, end_on_exit=False) while
_handle_request, wrapped(*args, **kwargs), and synchronous response handling
execute, so telemetry and nested spans use the client span context. Ensure
OCIGenAIStreamWrapper.events() and _finish_streaming_span also reactivate this
same span before emitting response events or recording metrics, while preserving
the existing explicit span.end() behavior.

GeneratorExit as an incomplete or cancelled stream rather than successful
completion, while preserving successful finalization only for normal exhaustion.
Override OCIGenAIStreamWrapper.close to close the wrapped SSEClient and finalize
the span with the incomplete or cancelled status when the stream is abandoned or
explicitly closed.

- Run request handling, the SDK call and synchronous response handling under use_span(span, end_on_exit=False) so emitted GenAI events carry the client span's trace context and spans created inside the SDK call become children instead of siblings. The span is reactivated while the SSE stream is read (never across a yield) and in _finish_streaming_span before response events and metrics are recorded. - OCIGenAIStreamWrapper: GeneratorExit and other BaseExceptions finish the span as incomplete (status left UNSET, partial output kept), close() closes the wrapped SSEClient and finishes the span, and only a stream consumed to the end is marked OK. on_done now receives a complete flag. - README: alt text on the PyPI badge. - tests: restore TRACELOOP_TRACE_CONTENT through monkeypatch instead of deleting it; add span-context correlation and stream lifecycle tests.

Included review availability: Your plan provides up to 8 included reviews per hour; 7 remain after this review.
When the caller leaves the events() loop early (GeneratorExit, or any other BaseException), OCIGenAIStreamWrapper now closes the wrapped SSEClient after finishing the span as incomplete, instead of leaving the HTTP event source open until garbage collection. The close is best-effort: a failure is logged at debug level and never masks the exception being propagated. A later explicit close() by the caller stays safe, since requests/urllib3 treat a second close as a no-op. Tests assert the fake event source is closed on early exit (wrapper unit test and instrumented-client test) and that a failing close() does not raise or double-report the stream.
