Colored Petri Nets Enable Concurrent Application Correctness

An analysis recently explores colored Petri nets (CPNs) as a framework for building verifiable concurrent applications, arguing they map naturally to Rust's typestate and can express guards, multi-token joins, and timed transitions. The piece outlines concrete implementation strategies — in-memory Rust binaries or Postgres-backed transactions — and proposes validating the approach by reimplementing a scraper scheduler (spider-rs) to compare correctness, performance, and developer complexity.
