Axon comes with fully machine checked proofs that guarantee the correctness of the generated code. All code and proofs were written in Lean by Claude Code, with the correctness proofs eliminating any need to audit or examine any verified code. I present a development process for using these validation techniques, evaluate the use of this process during the development of the compiler, and discuss implications for other development efforts. https://arxiv.org/abs/2605.01660 Regards, John Levine, johnl@taugh.com, Taughannock Networks, Trumansburg NY Please consider the environment before reading this e-mail. https://jl.ly
