refua-regulatory

refua-regulatory is the Refua regulatory workflow and audit package. It helps teams follow drug regulation processes by turning campaign decisions and execution outputs into verifiable evidence bundles with end-to-end lineage across plans, tool calls, models, datasets, and generated artifacts.

What it provides

• Campaign decision extraction from campaign run outputs.
• Structured decision records (decisions.jsonl) with deterministic decision IDs.
• Model and data provenance capture per campaign decision.
• Lineage graph materialization (lineage.json) for traceability.
• Evidence bundle packaging with checksums (checksums.sha256).
• Integrity verification for audit handoff and compliance workflows.
• Regulatory checklist evaluation with strict and manual-review gates.
• Automatic comprehensive checklist generation during bundle build.
• Structured outputs that support internal regulatory readiness reviews before agency submission.

Install

cd refua-regulatory
pip install -e .

CLI

refua-regulatory --help

Build a bundle

refua-regulatory build \
  --campaign-run artifacts/kras_campaign_run.json \
  --output-dir artifacts/evidence/kras_run_001 \
  --data-manifest ~/.cache/refua-data/_meta/parquet/chembl_activity_ki_human/latest/manifest.json \
  --extra-artifact artifacts/candidate_run.json

Output bundle layout:

evidence/
  manifest.json
  decisions.jsonl
  lineage.json
  checksums.sha256
  artifacts/
    campaign_run.json
    data_manifests/
    extras/
  checklists/
    drug_discovery_comprehensive.json
    drug_discovery_comprehensive.md

By default, build auto-generates the drug_discovery_comprehensive checklist.

Build-time checklist controls:

refua-regulatory build \
  --campaign-run artifacts/kras_campaign_run.json \
  --output-dir artifacts/evidence/kras_run_001 \
  --checklist-template core \
  --checklist-template fda_cder_ai_ml \
  --checklist-strict

Disable checklist generation:

refua-regulatory build \
  --campaign-run artifacts/kras_campaign_run.json \
  --output-dir artifacts/evidence/kras_run_001 \
  --no-checklist

Verify a bundle

refua-regulatory verify --bundle-dir artifacts/evidence/kras_run_001

JSON mode:

refua-regulatory verify --bundle-dir artifacts/evidence/kras_run_001 --json

Show bundle summary

refua-regulatory summary --bundle-dir artifacts/evidence/kras_run_001

Run a regulatory checklist

Core automated checklist:

refua-regulatory checklist \
  --bundle-dir artifacts/evidence/kras_run_001 \
  --template drug_discovery_comprehensive \
  --strict

FDA/CDER-oriented template (includes manual-review items):

refua-regulatory checklist \
  --bundle-dir artifacts/evidence/kras_run_001 \
  --template fda_cder_ai_ml \
  --output-json artifacts/evidence/kras_run_001/checklist.json \
  --output-markdown artifacts/evidence/kras_run_001/checklist.md

Python API

from pathlib import Path

from refua_regulatory import build_evidence_bundle, verify_evidence_bundle

manifest = build_evidence_bundle(
    campaign_run_path=Path("artifacts/kras_campaign_run.json"),
    output_dir=Path("artifacts/evidence/kras_run_001"),
)

verification = verify_evidence_bundle(Path("artifacts/evidence/kras_run_001"))
print(manifest["bundle_id"], verification.ok)

Data and model provenance behavior

• Data provenance is loaded from explicit manifest paths (--data-manifest).
• refua-data parquet manifests are parsed directly for dataset IDs, versions, source URLs, and SHA256 checksums.
• Model provenance is inferred from executed tool outputs and optional CLI overrides (--model-name, --model-version).

Test

cd refua-regulatory
python -m pytest -q

Notes

• This package records reproducibility evidence; it does not claim biological efficacy.
• Regulatory submission requirements vary by jurisdiction and program type.
