## Executive Summary
What should ``verified'' mean when evaluating LLM-generated code? Many existing pipelines report a single verification number.

## Why It Matters (Strategic Analysis)
Single-metric verification in LLM code generation creates false trust by masking semantic vacuities and edge-case failures in generated programs. Exposing these failure surfaces necessitates integrating formal specification and rigorous multi-layered validation into automated software synthesis pipelines.
