TLAPS-Bench Authors Clarify: Proving Specs Does Not Mean Bug-Free Implementations

TLAPS-Bench uses agentic AI to build machine-checkable proofs for TLA+ specifications of real systems, helping find a read-consistency bug in SlateDB's WAL. Author tianyinxu clarified that it only verifies spec-level properties, so proving them does not mean the implementations are bug-free.
