Set Branch • AI Agent SDK

</div>

This is a method of the ContextTraceEmitter class in the context_events module.

Set current branch context for parallel execution tracking.

All subsequent events emitted from the current context (thread or asyncio task) include this branch_id until cleared. Concurrent branches each run in their own copied context, so they cannot overwrite each other’s branch.
