A retry with the same `request_id` enters this branch, returns that existing row, and deliberately skips `_start_run()` again, leaving the turn permanently unqueued. The enqueue operation needs durable recovery semantics (for example, rollback/mark the placeholders on failure or requeue only a known-unsent run) rather than treating every existing assistant row as an active replay. ########## superset/ai/page_context.py: ########## @@ -0,0 +1,372 @@ +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.
