# Missingness-aware rubric aggregation

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Aggregate supplied weighted rubric scores with exact normalized fractions and conservative lower/upper bounds for missing ratings. Optional threshold reports certain pass, certain fail or unknown; does not assign ratings or renormalize away missing criteria.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Aggregate an explicit agent evaluation rubric without hiding missing scores

## Outside this profile
- Extracting facts or judging truth, semantic correctness, evidence authenticity, causal effects, or production readiness
- Fetching data, executing models or user code, changing datasets, authorizing actions, or contacting live services
- Inferring population quality, statistical significance, uncertainty intervals, or generalization from a supplied sample
