Theorem 1 (Byzantine Resilience). Under the assumption of at most f < n/3 faulty nodes, JPPIV achieves interactive consistency: no correct node commits an invalid state.

Proof sketch. In classical PBFT, a faulty primary can push bad data. In JPPIV, even if P is faulty, the pull-challenge from random V_j forces cross-checking. The joint interactive phase requires 2f+1 verifiers to mutually confirm the push and pull proofs. Hence, an invalid state cannot gather the threshold of verified interactive signatures. ∎ joint push pull interactive verified

Theorem 2 (Liveness). Provided at least 2f+1 honest nodes, the protocol terminates within 3 message rounds (push, pull, joint commit).

In the early days of computational design, complex maneuvers often required inputting numbers into a command line and hitting "Enter" to see the result. It was a process of trial and error. | Scenario | Joint Push-Pull Interactive Verified |

Interactive design changed everything. In this context, "Interactive" means real-time feedback. When a designer clicks and drags on a complex surface using a Joint Push Pull tool, they see the geometry deform instantly on the screen.

This interactivity allows for "sculpting" rather than just "modeling." The designer can feel the form, nudging it millimeter by millimeter until the curve is perfect. This interactivity allows for "sculpting" rather than just

WebSockets, MQTT, or gRPC streaming support interactive push-pull. Avoid HTTP/1.1 for JPPIV—it is half-duplex. You need a full-duplex connection.
