_No response_

Start by reproducing the failure described after upgrading to 0.1.30 with an arbitrary prompt, then inspect the request and retry path that reports HTTP 529. Identify the affected platform, installation method, and relevant logs before narrowing the cause. Done means the service no longer repeatedly reports as busy and retries for this case, with a regression check.
