We compute the least checking that keeps such a system sound. It is an entropy of the costs of the changes, and an endless chain of improvements stays sound at finite cost exactly when that entropy is finite. A stack of checked layers costs more than its layers would cost alone. We also compute how many guesses a proposer needs before a right one appears: human authors come close to this least number, and language models need $1.5$ to $4.3$ times as many. Anaxia, an engine built on these laws, rebuilt the published 2016 counterexample to Steinberg's conjecture from the rules of a colouring problem alone. The engine is a work in progress, and its rules and search are being revised and extended for the open problems it has not yet settled. \par\medskip\upshape\noindent\textit{2020 Mathematics Subject Classification.} 68T05; 68T20; 94A17; 60J80; 05C15. \end{abstract} \keywords{recursive self-improvement; verification; entropy; automated discovery} \maketitle \makeatletter\renewcommand\l@subsection[2]{}\renewcommand\l@subsubsection[2]{}\makeatother \tableofcontents \input{sections/sec01_intro} \input{sections/sec02_history} \input{sections/sec02b_related} \input{sections/sec03_model} \input{sections/sec04_entropy} \input{sections/sec05_huffman} \input{sections/sec06_renyi} \input{sections/sec07_chains} \input{sections/sec08_singularity} \input{sections/sec08b_online} \input{sections/sec08c_agents} \input{sections/sec08d_gap} \input{sections/sec09_branching} \input{sections/sec09b_towers} \input{sections/sec12_network} \input{sections/sec10c_benchmark} \input{sections/sec10d_experiments} \input{sections/sec10g_construct} \input{sections/sec10f_hodge} \input{sections/sec11_status} \appendix \input{sections/appA_derivations} \input{sections/appB_checks} \input{sections/appC_hardware} \input{sections/appD_sources} \input{sections/sec08e_brains} \input{sections/sec10_scaling} \input{sections/sec10b_cases} \input{sections/declarations} \input{sections/bibliography} \end{document}
