AlignedRAG-Eval

AlignedRAG-Eval is a lightweight evaluation harness for RAG poisoning defenses. It builds the four-condition record used in our paper: clean and poisoned inputs, each with and without a defense. From saved answer files, it reports prevented targets, introduced targets, net target reduction, clean-side effects, and audit packets for semantic review.

This repository does not include benchmark corpora, API keys or external defense repositories. Please download external resources from their original maintainers and follow their licenses.

What is included

• aligned_rag/: evaluation, scoring, audit, defense-adapter, and JSONL harness code.
• examples/jsonl/: a tiny four-condition example that runs without GPUs or external data.
• paper_artifacts/audit/: audit packets and completed labels used for the paper's validation checks.
• phase1_pilot.py, run_defenses.py, run_generalization.py: scripts for the larger PoisonedRAG, detector, and generalization experiments.
• requirements-phase1.txt, requirements-defense-suite.txt: requirements for the main experiment paths.

Install

For the lightweight JSONL harness:

python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -e .

For the full experiment scripts, also install the extra requirements:

python -m pip install -r requirements-phase1.txt
python -m pip install -r requirements-defense-suite.txt
python -m spacy download en_core_web_sm
python - <<'PY'
import nltk
nltk.download('stopwords')
PY

Install PyTorch and vLLM separately for your CUDA version if you plan to run model generation or detector scoring. The JSONL harness itself does not require a GPU.

Quick start

This example checks that the artifact can emit the four-condition record, transition table, P/J/N/H diagnostics, and audit packet.

  --out examples/outputs

aligned-rag-eval audit-export \
  --records examples/outputs/record_example.json \
  --out examples/outputs/audit_packet_example.json

The report directory contains:

• summary.json: aggregate four-condition diagnostics.
• p_j_n_h.csv: prevented targets (P), introduced targets (J), net reduction (N=P-J), clean-target change (H), and factorial contrast (Gamma=N+H).
• transitions.csv: query-level transitions between undefended and defended answers.

Input format

Each input file is JSONL with one object per query. The four files must contain the same query_id values.

Required fields:

{"query_id": "q1", "question": "...", "answer": "..."}

Recommended fields:

{
  "query_id": "q1",
  "group_id": "g1",
  "question": "Who plays the main character in Hacksaw Ridge?",
  "target": "Tom Hanks",
  "references": ["Andrew Garfield"],
  "reference_source": "benchmark",
  "answer": "Tom Hanks."
}

The automatic report uses target-string containment for reproducible diagnostics. Use the exported audit packet for LLM or human labels of target endorsement, reference correctness, and abstention.

External resources for full experiments

The full experiments use external datasets, attacks, retrievers, and defense code. Place them under data/ and baselines/, or pass custom paths to the scripts.

mkdir -p data baselines

Recommended external resources:

• PoisonedRAG attack artifacts and code: baselines/PoisonedRAG
• RobustRAG defense code: baselines/RobustRAG
• TrustRAG defense code: baselines/TrustRAG
• HotpotQA and Natural Questions through BEIR or the original benchmark releases
• DPR Wikipedia passages for DPR-style NQ setups
• Hugging Face model checkpoints for Contriever, BGE, Llama, Mistral, and other victim models used in reproduction

The scripts include commands for importing BEIR corpora and building local SQLite corpora, for example:

python -m aligned_rag.cli download-beir --dataset hotpotqa --out-dir data/downloads
python -m aligned_rag.cli import-corpus \
  --input data/downloads/hotpotqa/corpus.jsonl \
  --format beir-jsonl \
  --out-dir data/hotpotqa_sqlite

We thank the authors of PoisonedRAG, RobustRAG, TrustRAG, HotpotQA, Natural Questions, BEIR, DPR, Contriever, BGE, Hugging Face models, and vLLM for releasing the resources that make this evaluation possible. Please cite their original work and follow the license terms for each resource.

Audit artifacts

paper_artifacts/audit/ contains the audit material released with the paper. The headline audit sample deliberately oversamples contested transitions and judge-uncertain cases, so it checks label behavior rather than estimating population-level judge accuracy.
