Engine Overview

This guide provides a quick orientation to the solver engines and how their docs are organized.

Projects

• PRAXIS (Rust): primary probabilistic risk analysis solver
  • Docs: PRAXIS API
• SCRAM (C++): fault tree analysis engine with Node.js bindings
  • Docs (C++): Classes index
  • Docs (C++): Files index
  • Docs (C++): Namespaces index
  • Docs (TS bindings): scram-node API

Tech stack

• PRAXIS: Rust (nightly), compiled to a native binary
• SCRAM: C++ engine with Node.js bindings via node-addon-api and cmake-js
• Nx for orchestration; pnpm for package management

Conventions

• C++ docs focus on the public API; internal and third-party namespaces are excluded from navigation.
• PRAXIS API docs are generated with cargo-docs-md from rustdoc JSON output.
• Source for SCRAM lives under packages/engine/scram; PRAXIS lives under apps/solvers/praxis.
