        DETECTION LOGIC: Add a LintQ detector 'serializer-backend-divergence' that, during deserialization, verifies the reconstructed object is byte/value-equivalent to the serialized form (round-trip invariant) and warns when a payload was written by a different major version. Implementation: wrap load()/dumps() and assert obj == loads(dumps(obj)); flag version skew via an embedded version field. Catches silent read/write divergence before users hit it.
