Alex OS is the reasoning layer behind this website — a separate FastAPI service that sits between the CMS and the public site. It reads the content registry, reasons over it through configurable profiles, and returns structured recommendations, answers, and actions. It's enhancement-only: if the service goes offline, the core site still works normally.
It runs as its own service alongside the CMS rather than inside it. It reads the published content registry, embeds it, retrieves against a question, and reasons over the result through configurable profiles before returning a structured answer, recommendation or action. The separation is deliberate and the dependency is one-way: the public site calls Alex OS for enhancement, so if the service is unavailable, pages render and navigation works exactly as before — the visitor loses the assistant, not the site.
