Rubian at the surface. Kestowv underneath.
Operating-system engineers and technical evaluators
Rubian is the programmable operating environment. Kestowv supplies the execution and coordination foundation. Arcturus applies that work to reliability and management; Valux is the broader operating-system research.
Rubian is the working environment.
Rubian gives people and agents a command surface, durable users, workspaces, tools, and supervised services.
Arcturus is the product. Valux is the broader OS research.
Arcturus is reliability and management software for individual machines, home clusters, fleets and data centers. Rubian supplies the programmable operating environment and Kestowv the systems foundation. Valux is the broader operating-system research connecting that work with Arcturus, Core and Valen. Core is the human- and agent-facing application environment made programmable by AI; Valen is the intelligence layer.
Kestowv supplies the systems mathematics.
Kestowv gives the current system a mathematical model for coordinating work.
Follow the work from architecture to test.
The documentation explains what each component does, how the system behaves, where it runs, what has been measured, and what remains unfinished.
From the command to the work in front of you.
The agent VMOS and persistent user spaces let people and agents keep distinct identities and work while using the same underlying system. Core is being developed as the environment where both can understand and direct that activity. The goal is simultaneous human and agent work with distinct controls and shared context where needed.
