October 10 gate audit: no reopening trigger

Run run:5526c8e8-b8a3-453a-aff8-02cbc020a2ba · first-party source retrieval 2026-10-10T00:36:33Z–00:38:00Z · compared with the October 9 audit and R5’s September 24 cutoff. Read-only review; no inference, old-ID access, quota or benchmark requests (n=0).

Decision
Keep R5’s routine-monitoring wind-down. None of the four primary-source reopening gates was met. The October 9 description of the separate, mutable 26.10 Preview remains the prior update, not a new October 10 development.

One scoped source detail

The official pareto-evals .gitignore explicitly ignores results/. Its README and root listing still describe a configurable harness with locally generated output, not an inspected immutable run package. The direct results-tree URL remained uninspectable; a separate HTTPS attempt was blocked by sandbox DNS, not an HTTP 404. The ignore rule and failed inspection do not prove that no artifact exists elsewhere. They do not supply raw per-task results or a Union Alpha score. [T-S10–11]

Unchanged gates on inspected sources

Reopening gateOctober 10 resultEvidence boundary
Fixed former-alias linkageNot met. OpenRouter’s historical page still attributes its retired preview to Pareto by Unbiased.No exact former-alias-to-version, configuration and date mapping. The former Go alias is absent from inspected docs, catalog and changelog. Page and catalog observations are not old-ID endpoint tests. [T-S01–02, T-S05]
Benchmark artifact or independent reproductionNot met. The 26.10/26.9 chart remains preliminary provider material; the public eval repository is a configurable harness.No inspected immutable per-task package, complete scoring/cost method or independent reproduction. The chart is not a Union Alpha result. [T-S06, T-S10–11]
Official former-alias re-listingNot met. Exact stealth/union-alpha is absent from the inspected OpenRouter catalog; the Go alias is absent from inspected current Go surfaces.Source absence is not permanent unavailability proof or a direct access result. The separately listed 26.10 Preview is not a former-alias re-listing. [T-S02, T-S04–05]
Material older-route policy changeNot met. Older paid unbiased/pareto remains separately listed with no like-for-like price, context, retirement or route-policy delta from October 9.Generic limits and per_request_limits: null are not a numeric route quota. Direct-service plan RPM and terms cannot be transferred to OpenRouter or former aliases. [T-S02–04, T-S07–09]

Scope: this was a bounded public-source delta check, not a new Union Alpha technical evaluation. The candidate answer and access guidance remain unchanged except for the dated check. Full retrieval notes and source ledger are retained with this run’s research record.
