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

achieves up to a 59.7× reduction in execution time compared to standard baselines

C2weakest assumption

That the commutativity of C-Phase operations can be safely exploited in the lattice-surgery fault-tolerant setting without introducing logical errors, and that the dynamic event-driven scheduler can model spatial and routing constraints with negligible overhead.

C3one line summary

A microarchitecture-aware compiler for lattice surgery that exploits C-Phase commutativity to enable concurrent multi-target operations and dynamic event-driven scheduling, cutting execution time by up to 59.7 times versus standard baselines.
