Download ULM-PD Engine
Locally executing, invariant-enforced execution engine.
What you are downloading
The ULM-PD Engine download provides the complete local execution engine, including the natural language interface, invariant enforcement, symbolic execution infrastructure, refusal logic, and deterministic evaluation pathways. The engine package is made available for download only after the purchase of a valid licence plan.
A licence grants access only to the invariant packs and domain execution surfaces explicitly purchased. Domain and invariant access is controlled exclusively by an explicit licence file evaluated locally by the engine.
Natural-language input is used only for intent formation and routing.
Natural-language interpretation requires a valid OpenAI-compatible API key supplied by the user. Domain selection and routing from natural-language input therefore depend on a remote interpretation service.
Once a domain execution surface is selected, all validation, invariant enforcement, symbolic execution, and result generation occur locally and deterministically. ChatGPT is used solely for intent interpretation and routing and performs no mathematical or symbolic computation.
The external model used for intent interpretation may change between releases. Such changes do not affect execution semantics, invariant enforcement, or deterministic behaviour.
Platform support
- Linux: Native execution
- Windows: Supported via Windows Subsystem for Linux (WSL)
ULM-PD Engine is distributed as a Linux executable. Windows systems must run the engine within a WSL environment.

Licensing
The engine cannot execute any domains or invariant packs without a valid licence file.
Licences are evaluated locally. No continuous network connection is required for execution.
