The operating system operates on a strictly immutable model. It boots from a read-only state directly into RAM. Every time the system restarts, it completely wipes any user data, browser history, cookies, or downloaded files. This ephemeral architecture makes it practically immune to malware, persistent hacking attempts, and configuration tampering by malicious actors or accidental users.
