# Verifier Battery

## Definition

The ordered stack of checks that decide whether an output ships: deterministic gates first (cheap, sharp, false-negative-free), graded checks second (LLM or human judges, always from a different provider than the generator), each carrying its precision weight from a reliability ledger entry. Cliffs refuse; graded checks scale the q-score.

## Why this term exists

A single grader is a single point of failure with no second opinion. A battery composed in the right order - cheap-and-sharp before expensive-and-fuzzy, generator and adversary on different providers - turns evaluation into a structured search instead of a vibe call, and gives reliability a place to attach per-checker rather than per-pipeline.
