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

These results identify basis-selective readout and channel-selective absorption as experimentally relevant signatures of engineered electric-magnetic photodetection.

C2weakest assumption

The detector response can be engineered via cavity, superconducting, or metamaterial structures so that electric and magnetic field amplitudes contribute coherently to the detection operator rather than being restricted to the electric field alone.

C3one line summary

A generalized photodetection model with coherent electric-magnetic contributions shows complete amplitude cancellation in far-field geometry, continuous basis rotation in single-photon settings, and dark monitored channels with internal absorption at critical coupling.
