S5 Type / expected artifact: empirical / empirical / paper_text Claim: For Fig. 3d the total bit-flip probability is set to p = p_{down,down} + p_{up,up}, correcting for off-resonant excitation out of |up> caused by the changing radial mode tilt.

Conclusion

Claim: for Fig.3d total bit-flip p = p_{down,down} + p_{up,up}, correcting for off-resonant |up> excitation from changing radial mode tilt. This is a measurement-correction procedure combining two MEASURED single-ion excitation probabilities; the plotted p depends on measured data, none of which is released (inventory.json). Cannot reproduce; never synthesize. Procedure is internally consistent with Supp. S5 (normally |up,up> does not repump so p/2 from |down,down| suffices, but tilt-induced |up> excitation requires adding p_{up,up}). Verdict: data_unavailable.
