Scoring process

How this run was evaluated

This benchmark uses deterministic scoring. Published rules evaluate the response directly, so no AI judge is used and no judge cost is recorded.

Deterministic scoring

No judge required

The total cost is the tested model's inference cost.

Judge evidence

Independent assessment details

Not applicable. This suite uses deterministic scoring and requires no judge.

Run provenance

Versioned run identity

These timestamps delimit the recorded wall-clock lifecycle span. They do not measure active model execution time or comparable latency.

Authenticated publication

Signed release evidence

Most visitors only need the run JSON. The other files let auditors and developers independently verify the publication chain behind this result.

Start with this file

Recommended · this run

Single-run JSON

A sanitized, machine-readable copy of this exact result: model configuration, score, usage, execution, costs, judge summary and provenance. Best for reviewing, archiving or importing this run. The sanitized single-run JSON is a derived projection and is not separately signed.

Release verification files

These files work together. A single verification file is not useful on its own.

Release inventory

Public manifest

The signed inventory of this release. It lists every published file together with its SHA-256 digest and byte size.

Download signed manifest

Authenticity proof

Ed25519 signature

The detached signature over the exact manifest bytes. It lets the public detect whether the signed manifest was changed.

Verification key

Public key

The public verification key used to check the signature locally. It cannot be used to create a valid Kaelum signature.

Run index

A machine-readable directory of all 126 public runs, including their run IDs, benchmark versions and configuration references.

Benchmark dataset

Source aggregate

The complete published dataset for HGB Reporting, covering all model runs in this benchmark. Its hash and byte size are bound by the signed manifest.

The Ed25519 signature authenticates the exact public manifest bytes, including the release inventory. The manifest in turn binds this run's source aggregate by its SHA-256 digest and byte size.

Verify the evidence chain

  1. Verify the detached Ed25519 signature over the domain-prefixed exact manifest bytes using the published public key.
  2. Confirm that the sidecar payload SHA-256 equals the manifest SHA-256 shown above.
  3. Hash the source aggregate and compare its SHA-256 and byte size with the signed manifest entry.
  4. Resolve this run ID through the public run index and match its campaign ID inside that aggregate.
