Dynamic verification approaches support incrementality, but cannot provide static guarantees. To bridge this gap, prior work proposed gradual verification, which supports incrementality by allowing every assertion to be complete, partial, or omitted, and provides sound verification that smoothly scales from dynamic to static checking. The prior approach to gradual verification, however, was limited to programs without recursive data structures. This paper extends gradual verification to programs that manipulate recursive, mutable data structures on the heap. We address several technical challenges, such as semantically connecting iso- and equi-recursive interpretations of abstract predicates, and supporting gradual verification of heap ownership.
