Description
Describe the bug
When involving orchestration, HandOff in my example, ReasoningEffort setting is lost.
To Reproduce
Steps to reproduce the behavior:
- Create agent with GPT 5.4 and assign ReasoningEffort as "high"
- Create HandOff orchestration using created agent from step 1
- Invoke orchestration
- Observe HTTP request sent, reasoning_effort field is missing
Expected behavior
When using orchestration, I would expect to maintain reasoning level set on the agent, and that it is not lost during orchestration processing.
Screenshots

Research direction
Start with the attached Program.txt sample and trace how the agent's ReasoningEffort setting is carried through HandOff orchestration. Compare the outgoing request with and without orchestration, then verify that the request includes the expected reasoning_effort value when the orchestration is invoked.
