OptimaOS: A Rust Kernel That Boots on Real x86_64 Hardware

The Problem: Fragmentation Through Forking Android is a Linux fork. Embedded distros are forks with custom patches per SoC. AI stacks run on separate codebases. Each fork means a separate security audit, a separate team, and its own accumulating regression debt. The bet: one kernel binary for all scenarios. Profile differences are runtime policy, not a fork of the codebase. This is locked in ADR-0002 as Single Kernel + Runtime Profile Overlays . It Boots on Real Hardware POST UEFI MODE MM_OK INT
