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

transpilation acts as an implicit structural transformation of the optimization landscape, motivating compilation-aware analysis and co-design for VQCs.

C2weakest assumption

The differences in gradient statistics arise specifically from the structural changes imposed by satisfying hardware connectivity and gate-set constraints rather than from simulation artifacts or ansatz-specific choices.

C3one line summary

Hardware-aware compilation reshapes gradient statistics and trainability of variational quantum circuits in an architecture-dependent manner.
