Round 2 verification audit for C074

Model: gpt-5

Claim: The measured 93(1)% steady-state fidelity is consistent between datasets with and without shelving-error correction.

Source alignment: source/supp_content.tex:137-137 (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: measured 93(1)% steady-state fidelity is consistent between datasets with and without shelving-error correction (Supp. S5). This is a consistency statement between two MEASURED datasets, neither of which is released (inventory.json: no raw data). Cannot reproduce; never synthesize. The shelving correction handles off-resonant |up> excitation by the second 729 nm pulse via post-processing; reproducing the agreement would require the raw per-shot data and histogram-overlap parameters. Verdict: data_unavailable.
