cmdop vs the Landscape
cmdop is a persistent single-homed execution-state system: it holds runtime process, memory and filesystem state as a first-class, network-addressable primitive whose lifetime is independent of any client. Because that primitive resembles parts of several adjacent categories — cloud dev environments, isolated sandboxes, interactive kernels, terminal interfaces and autonomous agent frameworks — it is easily collapsed into one of them. The pages below compare cmdop with well-known systems at the level of architectural primitives, stating what is genuinely shared and where the design diverges. The frame throughout is neutral: shared primitives, divergence primitives, and the classification failure mode each comparison invites.
The single recurring divergence: in cmdop, execution state is the durable object and interfaces are interchangeable clients that attach to it as operators; in the systems below, execution is a property of an environment, a per-call sandbox, a transport-bound kernel link, a front-end interface, or an agent’s managed sub-component.
