Small enough to explain.

I / PURPOSE

Build to understand

Starting with a blank kernel makes every dependency a choice. We can teach the reason for an entry stack, watch the processor deliver a fault and test what survives when an application ends. Rust is the first choice for implementation; assembly is reserved for the boundaries where the CPU requires it.

II / METHOD

Make the claim observable

Each mission asks a question small enough to answer in a real VM. A printed message alone cannot prove that an app ran in user mode. Independent register and page-table inspection can corroborate it. A timeout must be recorded as a failure when the guest was expected to regain control.

III / HORIZON

A Kingdom in the stars

The celestial identity expresses a long view: small systems, explicit resource budgets and the ability to operate locally. Space is an inspiration, not a claim of flight qualification. The first practical destination is a VM that can host useful applications and services.

Kingdoms host applications; Realms are meant to hold people’s belongings. Giving a program a place to run should never silently give it access to someone’s documents.
