1What is an error?Draft 1 · · Established: The distinctions between error, bad outcome, surprise and imperfection are argued from the cited sources and the author's notes. The Mars Climate Orbiter and US Airways 1549 facts come from the investigation reports listed at the end; the Replit case comes from public posts by the user and by Replit's chief executive, and what is known only from the agent's own replies is marked as such. All checked 2026-10-24. The four conditions are the study's working definition, agreed on 2026-10-09; how each is applied is still a proposal. · Not established: No test of the framework has been run. Whether the four-condition definition is right or complete, whether error and mistake are one thing or two, and whether errors exist only under one interpretation or always are open questions. The Replit walk-through is an illustration, not an assessment. Nothing here shows that the framework can predict any error, an AI agent's included. · agent-drafted, not adopted
2Why do errors always exist?Draft 1 · · Established: The cited facts and quoted passages (the 1994 honours-thesis study, Carroll's map, Box on models, Hayek, Ashby, Clausewitz, the Rogers Commission report and Feynman's appendix on Challenger, Popov and colleagues' block-stacking task and DeepMind's survey of specification gaming, the Claude 3.7 Sonnet system card, Haselton and Nettle, and Legendre) come from the sources listed at the end, checked 2026-10-24. · Not established: The argument that errors cannot be eliminated is the author's proposal, not a tested result; whether the book claims that errors always exist, or that they appear wherever a limited model meets conditions it was not built for, is not decided. Not established: whether an error needs a cost; which errors are critical, or whether they can be recognised in advance; the scale hypothesis about AI agents, stated only as a working hypothesis with no completed test; any ability of the framework to predict errors, an AI agent's included. · agent-drafted, not adopted
