Dynamic circuits can either preserve interference-compatible histories or refine them by producing durable records. We report a replicated superconducting-hardware experiment that tests this distinction in a charge-conditioned edge-composition motif. In the graph-strict interpretation used here, a charge code is not an extra entity above the directed acyclic graph: it is a stable macro-state label whose outgoing edge-update rule is reusable. Opposite charge codes condition the same hardware graph in opposite coherent transport directions, while dynamic-neutral, zero-loop-phase, and same-loop-phase redistribution controls remain bounded under a frozen acceptance ledger. The decisive control is record/eraser orthogonality: durable path-record extraction suppresses the coherent charge-odd response, whereas eraser, measurement/reset-only, and dummy-record controls preserve it. The accepted run family includes a primary execution, a disjoint-lane same-backend replication, and a cross-backend replication, with raw histograms, circuits, manifests, figures, and reconstruction scripts archived in the accompanying data supplement. The result is an operational demonstration of a structured context discriminator: charge conditions edge composition; records resolve histories. It does not establish physical electromagnetism, Maxwell equations, Lorentz force, physical gauge invariance, Fisher/Poirier signed-Q dynamics, or a universal scalar record-rate clock law.
