+
+## Resolution
+
+`poll_inference` no longer propagates `result_channel.send(...)` with `?`.
+Instead, live-result delivery is routed through a small helper that
+tracks whether the frontend listener has already been lost:
+
+- First send failure: mark the result listener as unavailable, log a
+  warning, and best-effort send a `LiveStatusMessage::Warning`
+  explaining that transcription will continue in the background until
+  the user stops the session.
+- Subsequent chunks: skip re-sending to the dead result channel and
+  keep the worker running.
+
+Crucially, this path is now separate from actual transcription failure:
+inference errors still emit `LiveStatusMessage::Error` and stop the
+session, while listener-loss just stops live preview delivery.
+
+Regression test:
+
+- `result_listener_loss_is_warned_once_and_not_treated_as_inference_failure`
+  simulates a dead result channel, confirms the first processed chunk
+  downgrades to a warning, and confirms a second chunk still processes
+  successfully without a second warning.
