 # VeBench
 
-Labeled corpora for **VeRA: Mining and Verifying Feature-Pipeline Rewrites with
-an MLIR-Style IR and SMT** (ICDE 2026). Each item is labeled with lowering
-status, admission tier (Tier P proof / Tier E test), guard, and verdict.
+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.
