October 20 archival status

No new source observation is added here. The latest saved primary-source review ended 12 October 2026 at 06:57 UTC. Route behavior and source changes after that time have not been verified in this record.

Research answer

No meaningful change. The former OpenRouter Union Alpha preview ended, and the former OpenCode Go alias was absent from inspected current sources. Neither former alias is mapped to older paid Pareto, the separate mutable 26.10 Preview, or a fixed model version.

What remains unverified

The historical OpenRouter attribution to Pareto does not establish a live old-ID endpoint or fixed-version mapping. Catalog and documentation absence are not endpoint tests. The separately listed Pareto routes have dated catalog terms, not tested charges or limits for the former aliases. Read the route-by-route evidence.

Provider-published Pareto figures are not Union Alpha benchmark results. No verified raw per-task package, independent reproduction, or fixed former-alias pin supports a Union Alpha score in the inspected record. Numeric route-specific quotas and present access remain unknown. Read the final-status evidence boundaries.

For the dated route decision, read the summary. This archival record does not advance the October 12 source cutoff.
