A2A task delegation
The current task interface replaces the old chat API documentation.

Use the current delegation path
The old chat WebUI endpoint has been removed. The voice assistant delegates through authenticated A2A JSON-RPC to the task agent. This page keeps its original URL so existing bookmarks still lead to current information.
The source exposes task submission, streamed results, task inspection and cancellation through the A2A SDK integration. Read docs/reference/API.md and docs/architecture/dual-brain.md in your source package for the protocol and configuration.
A task has a lifecycle
The executor serializes work for the shared agent, streams progress and artifacts, and tracks cancellation. A client timeout bounds the waiting period; it does not roll back a tool action already completed.
