Why this status
Newly added. Sources are not archived and no value has been traced to one yet — run `npm run enrich`. Downgraded: context_window comes from the lab's documentation, but attribute-facts could not read an archived snapshot that states it, so the figure is not yet traced to a quoted sentence. reconcile-status upgrades it once attribute-facts succeeds.

What changed from Gemini 3.7 Flash
Compared with the previous release in this series. A field appears only when both records state a value — where one does not, it is listed as uncomparable rather than dropped, because a gap in our research is not a finding about the model.
Not comparable: Parameters (not researched on both releases)
