Formal verification of compiler robustness

Establish a formally verified robustness guarantee for the Context Compilation Architecture’s context compiler, ensuring safe behavior when adversarial deployments produce unparseable intermediate representations or otherwise malformed compiler outputs.

Background

The Context Compilation Architecture depends on a language-model compiler to transform each raw context into a typed JSON intermediate representation. Although fewer than 1% of context groups produced unparseable intermediate representations in the reported evaluation, the current implementation handles these cases through graceful fallback to direct prompting rather than through a formal safety guarantee.

The authors explicitly leave unresolved the task of hardening this fallback and parsing behavior into a formally verified property suitable for safety-critical and adversarial deployments. The open problem concerns robustness assurance for the compiler component, not merely reducing the empirical failure rate.

Unparseable IRs occurred for $<1\%$ of context groups in our evaluation, all absorbed by graceful fallback to direct prompting; hardening this into a formally verified property for safety-critical adversarial deployments is left to future work.
