Course redesign puts software specification front and center for first-year students and builds a tiny custom language that adds contracts and property-based testing plus a lightweight concurrency model so assignments actually include a timing side‑channel fix, a compiler optimization proof, multiple maze representation roundtrips, a simple memory allocator, and a working Lamport snapshot implementation. Runtime contract checks and generated test inputs find counterexamples quickly, student interviews report better transfer to real tools, and course artifacts and code are available for reuse.
