Exploring AI-first development, coding guardrails, and the architecture of disposability.https://autotomy.dev/https://autotomy.dev/blog/ai-safety-stack-types-contracts-property-tests-mutation/https://autotomy.dev/blog/ai-safety-stack-types-contracts-property-tests-mutation/If you want AI-generated code to survive production, do not rely on code review alone. Build a layered safety stack from type constraints through mutation testing and runtime containment.Sat, 16 May 2026 00:00:00 GMThttps://autotomy.dev/blog/why-great-engineering-ideas-stayed-niche-until-ai/https://autotomy.dev/blog/why-great-engineering-ideas-stayed-niche-until-ai/Design by contract, property-based testing, mutation testing, and model checking were not bad ideas. They were too expertise-heavy to sustain. AI changes that equation.Fri, 15 May 2026 00:00:00 GMThttps://autotomy.dev/blog/app-lifecycle-resume-status/https://autotomy.dev/blog/app-lifecycle-resume-status/Your app works fine in dev, but users get a blank screen when they return after lunch.
