When a live partial fails, the runner writes per-partial stderr to a temporary file such as live-partials/0003.err, but cleanup removes the whole tmpdir unless WAYSTT_LANWHISPER_KEEP_AUDIO=1.

Result: after the observed failure (partial failed 3), the exact curl/server error and offending WAV were already gone, making root-cause analysis impossible.

Expected behavior:

  • On failure, preserve diagnostic artifacts automatically, or at least copy/log the failing .err content before cleanup.
  • Include the failing segment path, file size/duration, curl exit code, and server response in session.log.
