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

this classical formulation remains highly competitive when implemented with modern insights, offering an excellent balance between simplicity, efficiency, and accuracy.

C2weakest assumption

That the classical quartic polynomial can be derived and solved in a numerically stable manner that matches or exceeds modern solvers without requiring problem-specific adjustments or additional constraints.

C3one line summary

The authors present a compact algebraic solver for the P3P problem using the classical Grunert formulation that achieves accuracy and runtime comparable to state-of-the-art methods.
