Jev-as-a-Judge
A confidence-gated evaluation pattern that accepts clear Jev judgments and escalates uncertain cases to a comparator or human reviewer.
This independently maintained workflow translates the cited Jev-as-a-Judge research into an auditable accept-or-escalate pattern. The research findings remain scoped to the paper experiments.

Workflow implementation guide
This editorial pattern requires local evaluation before operational use. Empty tested-version fields mean the directory has not run it against a pinned model release.
Business problem
Evaluation pipelines need a cheaper first-pass judge while preserving an escalation path for uncertain or high-impact cases.
Who this is for
Teams evaluating AI outputs with auditable acceptance and escalation rules.
Model selection notes
The workflow is derived from the cited paper and Jev confidence documentation. Type Safe has not reproduced the paper results or live-tested this example.

Detailed execution steps

- 2Obtain a Jev verdict and confidence.
- 3Validate the structured result.
- 4Accept only above a calibrated threshold.
- 5Escalate uncertain cases to a stronger comparator or human reviewer.
- 6Record both judgments and final disposition.

Confidence policy
Tune separate acceptance and rejection behavior against labeled samples; do not copy a threshold from the paper without local evaluation.
Human review policy
Escalate low-confidence, safety-sensitive, policy-sensitive, and disputed cases even when the first-pass verdict is accept.
Privacy notes
Store the minimum evaluation text needed for audit and apply retention and access controls to model outputs.
Cost notes
The paper reports performance within three points of its strongest comparator on selected tasks at 0.36% of that comparator fee, and a confidence cascade retaining 99% of comparator accuracy. These are scoped research findings, not a production guarantee.
Common failure modes
- ✓Threshold overfits one dataset
- ✓Comparator disagreement is discarded
- ✓Research result is generalized beyond tested tasks
Troubleshooting
- ✓Track coverage and accuracy together.
- ✓Review disagreement samples.
- ✓Version rubrics, thresholds, and comparator settings.

Keep the declared inputs and outputs visible in code review. Validate every model response before it reaches a database, API, or customer-facing action.
