flagtengu_concurrent_onquery_detected
An analytics event, not a feature flag. Claude Code logs it, with no fields, when a new query is submitted while another query is still running; the new query does not run, and its user prompts (other than some internal and notification messages) are put back on the input queue.

Is this right?

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
