Formal Methods Foundations

Turn a requirement into a checkable property and report precisely what the evidence establishes. A verified finite abstraction is evidence about that abstraction; implementation correctness needs a demonstrated correspondence.

When to use

Triggers: “prove this invariant”, “model check this workflow”, “safety versus liveness”, “temporal specification”, “SAT/SMT verification”, “refinement mapping”, “find a counterexample”.

A routine unit-test request belongs to testing; protocol design belongs to distributed systems. Use this skill when the specification, formal property, or verification boundary is the central question.
