The Authoring Lifecycle: A Comprehensive Methodology for AI-Native Software Architecture

AI introduces the Authoring Lifecycle, a proprietary methodology that fundamentally shifts software engineering from "Software Development" to "Software Authoring" due to the advanced capabilities of Large Language Models (LLMs). This methodology posits that the primary unit of value shifts from the codebase itself to the context used to generate it, and aims to counteract the inherent flaws of LLMs, such as sycophancy and context drift. The system is structured around two main protocols: the ISDE Protocol (Ideation, Selection, Documentation, Execution), which creates an immutable "Prompt Packet" or "Bible" before code is generated, and the ISOS Protocol (Infrastructure, Stress, Observability, Security), which hardens the resulting "soft" software through adversarial testing and automated governance. Crucially, the approach enforces Stateless Coding and treats code as disposable, advocating for replacement over repair, which enables a single human operator, the "Party of One," to execute the functions of an entire traditional software team.
