Guardrail: Automated Integrity Constraint Synthesis From Noisy Data

Summary: Guardrail expresses integrity constraints as programs in a DSL that can be synthesized robustly from noisy data to detect and repair errors beyond classical FDs. Its synthesis algorithm uses statistical structural priors to sketch and prune search, yielding ~87% error reduction on ML‑augmented SQL across real datasets (open-source).
