When that stream later reaches exhaustion or exits its context,_process_complete_responseends its span before checking_mark_response_emittedand ignores theFalseresult.

Problem
esponses_wrappers.py keeps a module-global
esponses dict. Entries are inserted on create/get/streaming paths but only removed in cancel wrappers, so any response that finishes normally stays for the life of the process (#4473 reports OOM from retained TracedData). A later
etrieve/parse on an already completed response could also emit a degraded duplicate span.
Solution
esponse_status == "completed" so in-progress entries remain available for Responses.retrieve polling (CodeRabbit review on this PR).
responsesdict #4473 part 2).Testing
Agent dimension
streaming-state (observability memory retention on agent/response streams)
Core value
Completed agent Responses traces no longer pin TracedData for the process lifetime, and retrieve-after-complete no longer emits a degraded duplicate span.
