product_version is used as model only when it contains a space, indicating a human-readable marketing name (e.g. "ThinkCentre M910x"). Part numbers like "J26843-409" have no space and are skipped — product_name is used instead (e.g. "NUC6CAYH" for Intel NUC). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
