def key
  if async_preview?
    raise ActiveStorage::Preview::UnprocessedError unless preview_variant_processed?
    find_preview_variant_record.image.blob.key
  else
    super
  end
end

#processed ⇒ Object

Enqueue (or no-op if already done) the same ProcessJob the VariantWithRecord path uses, so Preview-side and VariantWithRecord-side processing converge on a single record-and-job machinery rather than the gem’s earlier two-path design (one writing to preview_image’s variant_records, one to the original blob’s).
