Runtime model
The Planner runtime, written in Lisp, manages the execution of Planner programs. Runtime-based languages rely on a host process to interpret or compile code at runtime rather than compiling entirely ahead-of-time to native machine code. This means running Planner programs requires the runtime to be present on the target system.
The choice of Lisp for the runtime gives Planner access to native performance, established platform abstractions, and existing ecosystem libraries.
