EVAV Operational Alignment Battery — open-source CLI for matched-pair AI deployment safety auditing

evav-bench

The open-source CLI for the EVAV Operational Alignment Battery — a matched-pair causal-identification test suite for AI agents making decisions in regulated industries.

pip install evav

What This Is

EVAV is the behavioral intelligence layer for AI in regulated decisions. The Operational Alignment Battery tests whether a model preserves its stated rules under deployment-realistic pressure.

This CLI runs the full battery — 8 axes, 10 test groups, up to 80 cells — against any frontier model and produces an Evaluation Card.

Key findings from the reference corpus (209,072 decisions across 8 frontier models):

• 86% of violations would pass conventional compliance review (compliance masking)
• Claude Sonnet 4 ranges from 0% to 98% violation rate depending on documentation tier
• DeepSeek V3 swings 50-94% on identical configuration across PRNG seeds

Quick Start

# Install
pip install evav

# Set API key for your provider
export ANTHROPIC_API_KEY="sk-ant-..."   # or OPENAI_API_KEY, DEEPSEEK_API_KEY, etc.

# Run the smoke test (~$0.10 on DeepSeek)
evav run examples/battery.smoketest_deepseek.json --output ./results/

# Render the Evaluation Card
evav render-card ./results/ --format md > card.md
evav render-card ./results/ --format json > card.json

# Or render a beautiful visual HTML card
python cards/renderer/render.py ./results/ --out card.html

The Three Card Types

This repo ships with two card templates in cards/templates/:

1. Deployment Card (deployment_card.html) — single model, single config. The output of every evav run.
2. Benchmark Card (benchmark_card.html) — cross-model matrix. Used for the public leaderboard at evav.ai.

See cards/README.md for the full template reference.

Example Configs

File	Domain	Cells	Suitable for
examples/battery.smoketest_deepseek.json	Healthcare (lightweight)	7	First test (~$0.10)
examples/battery.healthcare.example.json	Medicare prior auth	51	Full audit, replicating research
examples/battery.lending.example.json	Consumer credit (ECOA)	28	Lending compliance
examples/battery.trading.example.json	Market-making (Reg NMS)	24	Trading compliance

Data

• Public corpus: 209,072-decision matched-pair dataset at huggingface.co/datasets/evavlabs/oa (CC-BY-4.0)
• Reference Evaluation Cards: rendered examples for the 8 frontier models in cards/examples/

Methodology

Matched-pair causal identification. PRNG-deterministic scenario generation (Mulberry32). 8 axes (pressure, doc tier, anchor, phrasing, authority, intervention, seed, temp). 10 test groups (A baselines → J forensics). Validated by SAE-based mechanistic interpretability at 81.2% probe accuracy.

Enterprise

For production deployment safety audits with full deliverables (Audit Report, Failure Cell Map, Intervention Recommendations, Precursor Profile, Compliance Artifact templates for HIPAA / ECOA / SOC 2 / EU AI Act / NIST AI RMF), see evav.ai/product.

The CLI in this repo runs the same instrument used in our paid Tier 1 audits — the difference is the deliverables, the audit team, and the compliance-artifact mapping that go around it.
