October 12 source audit: no reopening trigger

Run run:e60478c1-268a-4d9f-9531-8825bfd3e7f6 · first-party source retrieval 2026-10-12T06:55:27Z–06:57:00Z · compared with the October 10 audit. Read-only review; no inference, old-ID access, quota or benchmark requests (n=0).

Decision
R6–R9 remain no-go; R5 routine-monitoring wind-down remains in force. The inspected sources supplied no fixed former-alias version mapping, qualifying raw benchmark package, official former-alias re-listing or active-route mapping, or material like-for-like change to the older paid route. No new Union Alpha technical or access result was established.

Official evaluation repository

The visible public repository root lists harness and code folders, but no results/ directory. The README describes comparison files and per-item JSONL as output from a local run. Its .gitignore still ignores results/. These observations do not provide raw results or prove that none exist elsewhere. [U-S01, U-S03]

The direct public recursive tree, tags and releases API URLs returned the browser tool's internal “not accessible” error, not HTTP 404 or verified empty responses. The HTML tags page was a cache miss. The HTML releases page said there were no releases, but its crawl was six days old and cannot settle the October 10–12 interval. A current complete artifact inventory remains unverified. [U-S02–03]

Gate results

GateOctober 12 resultEvidence boundary
R6 · fixed linkageNo-go. The historical OpenRouter page still attributes its former preview to Pareto by Unbiased.No exact former-alias-to-version/configuration/date mapping. The former Go alias was not found in inspected current docs, catalog or changelog. [U-S04, U-S06]
R7 · raw result or reproductionNo-go. No qualifying per-task result package or independent reproduction was verified.The public root observation is limited; direct tree, tags and releases inventory was uninspectable. The provider's preliminary chart is not a fixed Union Alpha result. [U-S01–03, U-S09]
R8 · former-alias re-listingNo-go. The exact former OpenRouter ID was absent from the inspected catalog; the Go alias was absent from inspected current Go surfaces.These are page/catalog observations, not old-ID endpoint tests or proof of permanent unavailability. The separate 26.10 Preview is not a former-alias re-listing. [U-S05–06, U-S08]
R9 · older-route policy deltaNo-go. Older paid unbiased/pareto remains separately listed with the October 10 price and context values.No inspected retirement/replacement statement, route-specific numeric quota or retention change. per_request_limits: null is not unlimited quota. Unbiased direct-service terms and historical stealth terms do not establish a like-for-like older-route delta. [U-S05, U-S07, U-S10–11]

The October 11 OpenCode v1.19.0 changelog entry covers unrelated product updates; it is a dated page change, not a Union Alpha finding. The separately listed 26.10 Preview was already recorded on October 9 and is not new here. [U-S06, U-S08]

Next step: no routine source check is scheduled after this one-time audit. Revisit only a qualifying primary-source lead or owner direction. The uninspectable URLs and cached release page leave a specific R7 evidence limit; they do not establish global artifact absence.
