The honest boundary of argument-space verification — and what the Evidence Locker adds
The article highlights recent findings in argument-space verification, pinpointing the limitations of verification commands that often fail to catch broader scope errors. It presents the Evidence Locker, a structured feedback mechanism, to improve contract definitions and verification processes. However, it notes significant challenges in detecting under-invalidation errors, drawing attention to the human element in crafting accurate requirements.
