Status: IN
Correctness is enforced by structural construction rather than runtime validation: immutable values and synchronized data structures prevent state corruption, while monotonic progressions (read cursors, window lifecycles) make regression unrepresentable — together eliminating entire bug classes at compile-time rather than catching them at runtime.
Both depth-2 conclusions prevent bugs structurally (immutability/sync vs. monotonic ratchets) rather than via checks, forming a unified construction-over-validation principle
