Charged 36/36 report merges, zero propagation steps and zero native calls. Elapsed 15.45 seconds.
Each original model/processing fixture is checked with all providers and with only the earlier future report present. Training rows, shared maps, domains and future endpoints are checked before known truth. These controls do not qualify complete-group fallback, the full width target, recording-scale errors or observational confidence. No integration, compiler, optimizer or aircraft read was used.
