`os-console` is the human-facing surface of the PointSav platform — a Command Ledger that connects to one [[totebox-os|Totebox]] and renders its state to the operator. It does not store data and does not run services; it is a high-fidelity terminal purpose-built around keyboard-driven operator flow. The reference point is the Bloomberg Terminal: a single keyboard, a small set of function keys, and a relentless focus on the operator's context. The binary is written from scratch in Rust for sub-50-millisecond cold start and a 15-megabyte footprint. This article covers how os-console runs, the F-key surface, the rendering stack, and the two operating modes.

## How it runs

`os-console` ships as a single executable. On the host operating system — Windows, macOS, or Linux — it acts as a Virtual Machine Monitor: it uses the host's native virtualisation API to create a small, isolated VM in RAM and boots an seL4 environment inside it.

## Single, unified, universal

`os-console` is one product. There is no "Home" edition and no "Pro" edition. An individual hosting one Totebox uses the same Command Ledger as the administrator of a Reporting Issuer aggregating hundreds. Commercial differentiation is determined by the presence or absence of `os-orchestration`, never by a tiered Console.
