Axial.Process represents external work as an immutable ProcessSpec. Building a specification performs no I/O. Process.run asks the IProcess service to interpret it in the current Flow runtime.

open Axial.Process

let version =
    Process.command "dotnet" [ "--version" ]
    |> Process.timeout (TimeSpan.FromSeconds 10)
    |> Process.run
`Process.command` creates a runnable one-stage specification. Configuration functions return updated values, and `Process.pipe` connects specifications through real standard streams. `Process.run` returns `Flow<#IHasProcess, ProcessError, ProcessResult>`; `Process.stream` returns output and completion events with backpressure.

The live interpreter receives its operational dependencies explicitly:

let process = Process.live clock fileSystem console
Supply it by implementing `IHasProcess` on the environment given to the workflow: 
type AppEnv =
    { Processes: IProcess }
    interface IHasProcess with member this.Process = this.Processes
Flow owns scheduling, cancellation, timeout racing, and scope cleanup. The live interpreter translates interruption into process-tree termination and cleans up every stage that started, including partial startup.
