Coverage
See what fraction of labeled rows remain automated at each candidate boundary.
Jev confidence threshold
Choose a fallback boundary from coverage and observed error together.
A higher threshold may reduce answered rows while improving observed reliability. A threshold sweep makes that tradeoff visible before integration.
A threshold is an operating choice, not a guarantee.
Observed error
Compare the measured error rate among answered rows rather than assuming confidence is calibrated.
Fallback load
Estimate how much work moves to a human or stronger-model path and keep a rollback plan.
