Make every domain verifiable

The verification layer
for AI

Logos builds verification infrastructure that makes AI agents deployable in correctness-sensitive domains: domain-specific knowledge is formalised into machine-checkable specifications, and agents iterate against a theorem prover until their code is proven correct.
