COBALT-TLA

Overview

COBALT-TLA is a neuro-symbolic verification architecture that integrates an LLM with the TLA+ TLC model checker in a tight loop.

Architecture Highlights

It uses the verifier as a hallucination-free oracle. The LLM generates TLA+ specifications and properties, the TLC model checker evaluates them, and the trace feedback is fed back to the LLM to refine the design or find exploits.

Significance

It provides a strong architectural precedent for the verifier as a first-class oracle rather than a post-hoc linter, and has discovered real exploits in practice.
