In the design these notes draw on, a live model endpoint is scored by other models and measured partly on machines the scoring operator does not run. These are working notes on both: who judges the output, and what makes a measurement evidence. They are for someone deciding what to demand of a score before relying on it, not whether to buy one.
Where a judge's vendor also makes models it scores, the judge is a party to the score. What a cross-provider panel and outlier rejection contain, and what they leave open.
Paper 002Per-judge records, a content-keyed cache and plane isolation make a panel legible to its operator. A cached verdict is repeatable, not reproducible, and a reader gets nothing to check.
Paper 003A signature shows which enrolled key signed a result and that its bytes did not change, not that the probe was honest. Where the signed chain stops, and why.
Paper 004Promotion shows a partner result agreed, not that it was right. A derived region places where traffic left, and a provider's worst hours can arrive as missing rows.
No score from the design these notes describe can be re-run by anyone other than its operator: neither these notes nor the operator's public pages publish a rubric, prompt set, panel composition or test suite. Published studies suggest a panel from several providers dilutes a judge's preference for its own family's output, unevenly and without removing it; a cached verdict is repeatable, not reproducible. A probe's signature binds its result to an enrolled key, not to the world, and no worker signature reaches past ingestion; whether later steps are signed is not described, and first-party results skip admission. The public delayed feed, read 14 September 2026, lists 18 model series from five providers and carries no member scores, test version, region or signature. These notes measure neither panel nor fleet, and leave open whether any score in it is sound.
FrontierScore, a Digital One property, is the provenance of this method, not its subject. Its repository is not public: the design described is its builders' account, none of it checkable today, and its scale figures are left out. Feed figures were counted from snapshots of its public delayed feed taken 14 September 2026. Deliberately absent: prices, plans and tiers, availability, and deployment internals.
