R3 route-status audit · 20 Sep 2026 UTC
Union Alpha is retired; its former Go alias is no longer listed
The historical OpenRouter preview is still attributed to Pareto by Unbiased, while the current paid unbiased/pareto route remains a separately scoped catalog listing. R3 found the former OpenCode Go alias absent from the current Go docs and public catalog. No request was sent: n = 0.
Decision
Do not start an integration on either former identifier. Do not use
stealth/union-alpha or configure opencode-go/union-alpha. A paid Pareto evaluation needs its own approved access, budget and current route-specific data-terms review.Former preview

unbiased/pareto is catalog-listed with paid metadata, but R3 did not test it or establish an immutable preview snapshot. R3-S03Former OpenCode Go alias

n = 0 requests
No old-slug or Go-alias request was sent. The Go alias lacked both a current listing and a pre-existing authorized credential. There is no R3 HTTP status, response, headers, latency, capacity, availability, tool, image, routing, or rate-limit observation.
Route decision record
| Identifier | What R3 documents | What it does not establish | Safe next action |
|---|---|---|---|
stealth/union-alpha | Historical reveal to Pareto; free period ended; omitted from current catalog. | Old-ID API behavior, a current quota, or current retention. | Do not integrate. Treat old specs and privacy wording as historical metadata. |
unbiased/pareto | Current paid listing; declared 262,144 context, 131,072 output, text/image input and tools/tool choice. | Paid entitlement, behavior, privacy, SLA, performance, components, or preview equivalence. | Evaluate only in a separately approved successor study. |
union-alpha / opencode-go/union-alpha | Absent from inspected current Go docs and public model catalog. | An HTTP error, entitlement, current price, quota, privacy policy, or mapping to Pareto. | Do not configure it. Monitor for an official re-listing and explicit mapping. |
Limit reader
Do not transfer claims across routes: historic Go “Unlimited” / 0-day wording is not current Union Alpha policy; generic OpenRouter free-variant rules are not a Union Alpha or Pareto quota; catalog telemetry is not an R3 capacity test.
What changed in R3
Sep 16 · R1Free anonymous preview listed; four environment attempts ended at DNS before HTTP.
Sep 18 · R2Preview was disclosed as Pareto by Unbiased; Go alias was documented but untested.
Sep 20 · R3Former Go alias is absent from inspected current Go docs/catalog; the audit sent zero requests and preserved the route-equivalence gap.
