Round 2 verification audit for C077

Model: gpt-5

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.

Source alignment: source/supp_content.tex:157-157 (Supp. Mat. S5)

Prior official verdict: not_verified with failure_reason data_unavailable.

Executable evidence: none. Sandbox rerun logs: none.

Independent audit: I checked the paper inventory and source context. This claim depends on measured/raw experimental data or device-specific calibration values, and inventory.json records no paper-provided dataset/code artifact. The correct action is not to synthesize data; the data_unavailable verdict is preserved.

Decision: Round 2 verdict is not_verified with failure_reason data_unavailable and limitations ['data_unavailable']. Notes: 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.
