SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Pact formal verification provides a framework to reason about function arguments, results, and database interactions using @model annotations, enabling invariant checks and counterexample analysis early in development.

Core Features & Use Cases

  • Property-based reasoning with @model on defun and defschema to encode correctness contracts.
  • Conservation proofs and reusable module properties to ensure data integrity.
  • Suitable for development, testing, and audit scenarios where formal guarantees are desired.

Quick Start

Annotate a sample defun with a simple @model property and then run typecheck to validate basic behavior.
