Could you build this?
No Designing a domain-specific language that formally compiles state machine logic into TLA+ specifications and integrates with TLC model checking requires deep expertise in formal methods and compiler theory.
What it would actually take: A production implementation requires building an AST parser and type checker for a TypeScript embedded DSL, a robust code generator targeting TLA+ syntax and semantics, and an orchestration layer that invokes the Java-based TLC model checker and translates counterexample traces back into TypeScript stack traces. The hardest part is ensuring semantic equivalence between TypeScript execution rules and TLA+ temporal logic while handling unbounded state spaces and concurrency primitives. This demands formal verification researchers and compiler engineers well-versed in Lamport's TLA+ specifications.
