The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

A key algorithmic innovation is a computationally efficient landing mechanism that replaces costly and often ill-defined projections onto Σ, ensuring feasibility without iterative Newton solves or projection failures.

C2weakest assumption

The landing mechanism works for generic nonconvex feasible sets Σ and preserves the correct diffusion dynamics without introducing bias or instability.

C3one line summary

A landing algorithm lets diffusion models sample from nonconvex constrained sets using underdamped dynamics without repeated projections or Newton solves.
