What I built is simple: I declared independence from the cloud for this specific routine. I took an old, dormant desktop and turned it into a headless, local-first automation server. ...

We have moved beyond “tools” and into the era of the AI-Driven Development Life Cycle (AIDLC)—an ecosystem where the machine doesn’t just assist the work; it executes the work. ...
