# VeBench

The labeled benchmark for **VeRA: Mining and Verifying Feature-Pipeline Rewrites
with an MLIR-Style IR and SMT** (ICDE 2026): nine components for verified
feature-pipeline rewrite mining. Generated components regenerate from fixed seeds
via the artifact (`scripts/export_bench.py`); real-code components ship as
license-stamped samples.
